FIELD OF THE INVENTION [0001] The present invention relates to a feed for cattle,

The present invention relates to a feed for cattle fattening and a method for feeding cattle fat using the cattle feed, and more particularly, to a feed for cattle fattening to improve meat quality of cattle fattening and a method for feeding cattle fat using the feed.

Recently, consumer consciousness structure of beef is changing from quantitative to qualitative satisfaction.

In addition, consumption of beef has been increasing in recent years due to increased interest in health and disease related to human life.

On the other hand, beef quality (beef quality) can be judged by institutional devices such as a carcass grading system, but it is very important to meet consumers' desire for purchasing since they are directly judged by the consumer.

Since most of the high quality meat is critically influenced by the degree of marbling of the fillet by the grading system, a variety of breeding techniques are applied to distribute the fat evenly in the fillet at the production site.

In recent years, interest in functional livestock products has been increasing, and there have been a growing number of cases where bioactive substances extracted from plants, biologically active substances extracted from plants, microbial agents, and antibiotic substitutes are added to Hanwoo.

Consumers who prefer livestock products are also interested in vascular diseases, livestock products contaminated with antibiotics, cancer and obesity, and immune enhancers.

Accordingly, the present applicant has developed a feed containing a functional sulfur, which is a functional substance, in a conventional feed for cattle feed, and a method for feeding cattle feed using the same.

An object of the present invention is to provide a feed for cattle fattening which improves the breeding ability and improves meat quality of beef cattle, and a method of feeding cattle fattening using the feed.

The object is achieved by a method for producing a feed composition comprising a feed composition comprising corn, wheat, molasses, wheat bran, wheat flour, conglutinous feed, soybean meal, soybean meal, palm oil, palm oil, salt, bicarbonate, vitamin preparation, mineral preparation, limestone, , 2154 g of total digestible nutrients, 6 g of natural sulfur, and 5 to 20 g of legal sulfur are further mixed.

It is another object of the present invention to provide a method for producing a fermented soybean oil which comprises the steps of mixing corn, wheat, molasses, tapioca, wheat bran, wheat flour, conglutinous feed, soybean meal, The feed composition including soybean oil is mixed with 755 g of crude protein, 4089 g of total digestible nutrients, 13 g of natural sulfur, and 5 to 20 g of legal sulfur are further mixed.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to improve the breeding ability and improve the meat quality of beef.

Hereinafter, the feed for cattle and the method for feeding cattle using the cattle according to the present invention will be described in detail.

The feed for cattle feed according to the present invention includes crude protein, total digestible nutrients (TDN), natural sulfur, and legal sulfur.

Here, crude protein, total digestible nutrients, and natural sulfur are used in corn, rye, wheat, wheat bran, molasses, tapioca, wheat bran, wheat flour, conglutinous feed, soybean meal, .

Crude proteins are those containing pure proteins and free amino acids, amides, ammonia compounds, glycosides, etc., which are non-protein nitrogen compounds.

The total amount of plasticized nutrients refers to nutrients that can be obtained by digestion and absorption of nutrients contained in mixed feeds in cattle.

Natural sulfur refers to the naturally occurring sulfur contained in compound feed.

On the other hand, natural sulfur and legal sulfur are components of glutathione, which is a component of sulfur amino acids (methionine, cystine) containing sulfuric acid and detoxification, and promotes collagen synthesis and is known to be essential for various growth factors. In addition, it has a keratin softening action and an antibacterial action of the skin, and is effective in the treatment of dermatosis, so that it has an innate effect on acne-causing bacteria and inflammation. In particular, the sulfur compounds contained in garlic and onion extracts have been widely used as a remedy for diseases such as typhoid fever, cholera, and dysentery before modern antibiotics are emerged and inhibit the growth of pathogenic microorganisms. There is about 0.15% of sulfur in the animal body, mainly in the form of bisulfate, and the remainder is in the form of inorganic taurate and thiosulfate. Microorganisms and bacteria in the rumen can transform sulfuric acid into methionine and cystine, and sulfur can function in the body. Since the intestinal microorganisms do not exist in the unit animal, Can not be synthesized. Therefore, it is necessary to feed sulfur amino acid containing sulfur from the outside as a source. In the case of ruminant livestock, sulfur feed increases milk production, improves cellulose digestibility in the rumen, and lack of sulfur reduces feed intake, decreases fibrin digestibility, and reduces the number of microbes in the rumen.

Hereinafter, each embodiment of the feed for cattle fattening according to the present invention will be described.

The feed for cattle fattening according to the first embodiment of the present invention is a feed for corn, wheat, molasses, wheat bran, wheat flour, conglutinous feed, soybean meal, seed meal, palm oil, palm oil, salt, The feed composition including soybean oil is mixed with 448 g of crude protein, 2154 g of total digestible nutrients, and 6 g of natural sulfur, and 5 to 20 g of legal sulfur is further mixed therein.

In addition, the feed for cattle fattening according to the second embodiment of the present invention can be applied to corn, wheat, molasses, tapioca, wheat bran, wheat flour, corn gluten feed, soybean meal, The feed composition, including the preparation, mineral preparation, limestone and soybean oil, is mixed with 755 g of crude protein, 4089 g of total digestible nutrients, and 13 g of natural sulfur, and mixed at a ratio of 5 to 20 g of legal sulfur.

The feed for cattle fattening according to the third embodiment of the present invention may be applied to corn, rye, wheat, wheat bran, molasses, tapioca, wheat bran, wheat flour, conglutinous feed, soybean meal, The feed composition, including salt, bicarbonate, vitamin preparation, mineral preparation, limestone and soybean oil, is mixed with 898 g of crude protein, 5464 g of total digestible nutrients, and 15 g of natural sulfur.

The method of feeding the feed for cattle according to the present invention will be described as follows.

The feed for cattle fat according to the first embodiment of the present invention, which is mixed at a ratio of 448 g of crude protein, 2154 g of total digestible nutrients, 6 g of natural sulfur and 5 to 20 g of legal sulfur, is fed daily to the cattle for 6 months to 12 months.

In addition, the feed for cattle fattening according to the second embodiment of the present invention, which is mixed at a ratio of 755 g of crude protein, 4089 g of total digestible nutrients, 13 g of natural sulfur and 5 to 20 g of legal sulfur, is fed daily at 13 to 20 months of age .

The feed for cattle fattening according to the third embodiment of the present invention mixed at a ratio of 898 g of crude protein, 5464 g of total digestible nutrients, 15 g of natural sulfur and 5 to 20 g of legal sulfur is fed daily to the cattle .

Thus, by selectively feeding the feed according to the present invention in accordance with the aging period of the growth stages of the beef cattle, the breeding ability can be improved and the meat quality of the beef can be improved.

Hereinafter, the experimental results of the cattle fed with the feed according to the present invention and the cattle fed without feeding the feed according to the present invention will be described in order to clarify the technical point of the present invention.

Prior to the explanation, the following experimental results were obtained from the breeding period until the release of the cattle. The feed diets varied according to the growth stage depending on the growth period (from 6 months to 12 months of age), the fattening period (from 13 months to 20 months after birth) and the late stage of fattening (T1: 5g, T2: 10g, T3: 15g, T4: 20g) according to the experimental treatments.

That is, in the following experimental data, in the case of the control group, irrespective of the age of the fattening cattle, no legal sulfur was fed, that is, in the case of the cattle fattening feed.

In the experimental treatment T1, the crude protein was 448g, the total digestible nutrient was 2154g, the natural sulfur was 6g, the legal sulfur was 5g daily, and the crude protein was 755g, the total digestible nutrients were 4089g, 13 grams of natural sulfur, 5 grams of legal sulfur, and 898 grams of crude protein, 5464 grams of total digestible nutrients, 15 grams of natural sulfur, 5 grams of legal sulfur, per day from 21 months after shipment.

In the experimental treatment T2, the crude protein was 448 g, the total digestible nutrient was 2154 g, the natural sulfur was 6 g, the legal sulfur was 10 g daily, and the crude protein was 755 g, the total digestible nutrients were 4089 g, 13 grams of natural sulfur, 10 grams of legal sulfur, and 898 grams of crude protein, 5464 grams of total digestible nutrients, 15 grams of natural sulfur, and 10 grams of legal sulfur are fed daily from 21 months after shipment.

In the experimental treatment group T3, crude protein (448 g), total digestible nutrients (2154 g), natural sulfur (6 g), and legal sulfur (15 g) were fed daily for 6 months to 12 months after birth and 755 g of crude protein, 4089 g of total digestible nutrients, 13g of natural sulfur, 15g of legal sulfur, and 898g of crude protein, 5464g of total digestible nutrients, 15g of natural sulfur and 15g of legal sulfur are fed daily from 21 months after shipment.

In the experimental treatment group T4, crude protein, total digestible nutrients, total digestible nutrients, total digestible nutrients, total digestible nutrients, total digestible nutrients, 13g of natural sulfur, 20g of legal sulfur, and 898g of crude protein, 5464g of total digestible nutrients, 15g of natural sulfur and 20g of legal sulfur are fed daily from 21 months after shipment.

First, Table 1 shows the results of experiments on the amount of feed and the rate of feed demand.

[Table 1]

As shown in Table 1, average daily gain (ADG) was 0.69, 0.70, 0.77, 0.80 and 0.76 kg in the control, T1, T2, T3 and T4, The results showed that the legal sulfur content was improved by 1.4 ~ 15.9%. In particular, the daily average gain (ADG) of the T3 group was significantly improved (p <0.05) compared to that of the control group, and the daily average gain (ADG) of the T2 and T4 groups was improved by 10% It looked. The dry matter intake (DMI) of the compound feed and rice straw was higher in the control (8.77 and 1.87 kg), T1 (9.26 and 2.20 kg), T2 (8.79 and 1.89 kg), T3 (9.10 and 1.93 kg) T4 (8.88 and 1.82 kg), respectively.

The feed conversion ratios of control, T1, T2, T3 and T4 were 13.12, 13.97, 11.85, 11.68 and 11.89, respectively, and T2, T3 and T4, except T1, were 9.7, 10.8, 9.4% (P <0.05), respectively.

Feeding ratios of rice straw were 2.80, 3.32, 2.55, 2.48 and 2.44 in the control, T1, T2, T3 and T4, respectively. The T2, T3 and T4 groups were improved (8.9 ~ 12.9% ), But no statistically significant difference was observed.

Feeding rate of 10 ~ 20g / day of sulfur was better than that of control. This shows that the feeding effect of both the formula and the forage is effective when the sulfur is fed, and this effect also affects the amount of gain.

In this study, the effect of legal sulfur on the weight gain, feed intake and feed conversion ratio of Hanwoo steers was improved. Therefore, it is considered that the benefit of the legal sulfur is effective on the ability to grow Korean Hanwoo steer, that is, the improvement effect on the cultivation ability by 10, 15 and 20g / There is a positive effect on the amount of feed and the rate of feed demand of Hanwoo steer when fed.

Next, Table 2 shows the results of experiments on the backfill thickness of the conductor grades.

[Table 2]

As shown in Table 2, the backfat thickness of the conductance of Hanwoo steers was 13.00, 13.01, 10.56, 12.40 and 13.8㎜ in the control, T1, T2, T3 and T4, T3, but there was no significant difference. Especially, T2 group showed the highest improvement of 18.77%.

The root lengths of the shoots were 95.26, 99.00, 101.47, 97.64 and 100.45cm 2 in the control, T1, T2, T3 and T4, respectively.

(P <0.05), respectively, in T1, T2, T3, and T4 groups compared with the control group, which were 65.14, 65.66, 67.37, 65.65 and 64.11, respectively.

Tuna, T1, T2, T3 and T4 were the highest in the T1 and T3 groups compared to the control group, which were 5.91, 6.70, 5.76, 6.36 and 5.55, respectively.

The meat color was highest in control group, T2, T3, T4, and T4 groups, 4.57, 4.80, 4.94, 4.48 and 4.73, respectively. 3.09, 3.00, 3.18, 2.84 and 3.27, respectively, which were higher in T2 and T4 than in the control.

On the other hand, the occurrence rate of meat grade was highest in the T2 group with 82, 90, 94, 80 and 72% in the A, B grades in the control, T1, T2, T3 and T4 groups, In T1, T2, T3 and T4, the rates of 1 ++, 1 +, and 1,2 grades were 57, 90, 44, 72 and 45%, respectively.

As a result of evaluating the results, it was found that the backfat thickness was reduced by feeding 10g / day and 15g / day of legal sulfur in carcass evaluation, and the cross - sectional area of abdominal muscle was increased when 5 ~ 20g / day of sulfur was fed . In addition, the effect of feeding 5g / day and 15g / day of legal sulfur showed that the intramuscular fat was increased, and the occurrence rate of carcass grade was improved by feeding 5 ~ 15g / day of legal sulfur.

[Table 3] shows the results of the experiment on the kneading ingredients of the fillet.

[Table 3]

As shown in Table 3, the crude protein contents of the control, T1, T2, T3 and T4 were 53.83, 50.93, 51.48, 52.03 and 56.80%, respectively, (P <0.05). The crude fat content of the control group was lower than that of the control group (46.91, 46.46, 48.09, 47.18, and 39.28%) in T1, T2, T3 and T4 groups.

The content of fiber was higher in the T1, T2, T3 and T3 groups than in the control group (p <0.05), and the T1, T2, T3 and T4 groups were 6.43, 13.06, 10.82, 10.92 and 6.40% (P <0.05). In the control group, T1, T2, T3 and T4 were 5.02, 2.94, 4.89, 4.41 and 5.76%, respectively.

The increase of crude fat content when 10 ~ 15g / day / head of legal sulfur was fed to Hanwoo steer increased the intramuscular fat content.

Next, Table 4 shows the results of experiments on the surface carcasses of the fillets.

[Table 4]

Meat color is a sensitive and changeable part of the specification management. The meat coloring does not reflect the nutrients, flavor and functional properties of meat but is actually an important quality factor that determines the taste and the desire of the consumer, and determines the color that directly affects the evaluation of the carcass grade.

As shown in Table 4, the lightness was 44.29, 45.60, 45.41, 44.54 and 44.56 in the control, T1, T2, T3 and T4, respectively, Respectively. This is probably due to the fact that the intramuscular fat content of the treatments was higher than that of the control as shown in the conductor results.

Redness, which is the most important determinant of meat coloring, was 12.63, 12.87, 12.59, 12.83 and 13.28 in the control, T1, T2, T3 and T4 groups, respectively. In the T1, T3 and T4 groups Yellowness was 5.41, 5.92, 6.14, 5.65 and 6.50 in the control, T1, T2, T3 and T4, respectively, which was higher in the treatments than in the control.

On the other hand, chroma, which is an index indicating the intensity of red color, was 13.84, 14.13, 14.03, 13.96 and 14.81 in the control, T1, T2, T3 and T4 Results. It is considered that the color of the hue angle is higher than that of the control by feeding the legal sulfur, and the taste of the consumer will be increased. 23.10, 24.48, 25.76, 23.57 and 26.13, respectively, which were higher than those of the control group.

These results suggest that redness and chroma, which are known to be the most important determinants of meat coloring, are improved, resulting in improved meat color.

[Table 5] and [Table 6] show the result of measuring TBARS (thiobarbituric acid reactive substance) and volatile basic nitrogen (VBN) to test the sourness of the loin.

[Table 5]

[Table 6]

First, as shown in Table 5, 0.35, 0.37, 0.35, 0.26, and 0.22 mg (ppm) were observed in the control, T1, T2, T3 and T4 groups at 0 day of the lipid peroxidation (TBARS) T3 and T4 were lower in the control, T1, T2, T3, and T4 than in the control, and 0.41, 0.30, 0.38, 0.36 and 0.33 mgMA / kg in the control, T1, Compared to the control group. In the control group, 0.52, 0.27, 0.43, 0.37 and 0.43 mgMA / kg were observed in the control, T1, T2, T3 and T4 groups, respectively. , T3 and T4 were 0.72, 0.26, 0.53, 0.43 and 0.51 mg MA / kg, respectively. Especially, T1 and T4 groups were significantly lower than control group (p <0.05). On the other hand, all treatments except T1 were increased gradually with the passage of storage period. In the present experiment, the sulfur content of the treated soy sauce was lower than that of the control soy sauce.

As shown in Table 6, the amounts of volatile basic nitrogen (VBN) were 17.09, 18.95, 16.87, 17.89 and 17.82 mg% in the control, T1, T2, T3 and T4 groups at the 0th day, T3 and T4. The contents of the control were lower in the T2 group than in the control group, but the contents of control, T1, T2, T3 and T4 were 18.29, 21.19, 17.32, 18.40 and 18.69㎎% . T2, T3 and T4 groups were lower in the control, T1, T2, T3 and T4 groups than in the control group at the 6th day and 19.78, 20.52, 18.41, 19.26 and 19.61㎎% , T3 and T4 were 21.64, 26.40, 20.17, 20.85 and 20.34㎎%, respectively, and T2, T3 and T4 were lower than those of the control. On the other hand, the content of volatile basic nitrogen (VBN) increased with storage period in all treatments. This means that during storage, muscle proteins are degraded into amino acids and various inorganic nitrogen species, which increases the volatile basic nitrogen (VBN) by the increase of amino acids and peptides due to the hydrolysis of proteins, It is also thought that it is affected by the formation of ammonia (ammonia) and the increase of nucleotides due to the decomposition of adenosine monophosphate (AMP).

In this experiment, the changes of volatile basic nitrogen (VBN) contents of T2, T3 and T4 groups fed 10, 15 and 20 g / day of volatile sulfur were decreased as the storage period was increased, It is considered that it is effective for the storage stability of roasted sirloin.

[Table 7] shows the results of an experiment on the minerals content of the fillet.

[Table 7]

As shown in Table 7, iron (Fe) content of Hanwoo steers according to the legal sulfur content was 82.01, 83.52, 93.04, 96.87 and 97.88 ppm in the control, T1, T2, T3 and T4, The results showed that the T1, T2, T3 and T4 spheres improved to 1.84, 13.45, 18.12 and 19.35%, respectively. The higher the sulfur content, the higher the iron (Fe) content was.

The contents of sulfur (S) in the control, T1, T2, T3 and T4 groups were 184.64, 251.55, 280.64, 297.70 and 318.93 ppm, respectively, which were 36.24 and 51.99 , 61.23, and 72.73%, respectively, especially in T3 and T4 groups (p <0.05).

The Zn contents of the control, T1, T2, T3 and T4 were 107.55, 120.38, 117.77, 122.53 and 146.77ppm, respectively. The concentrations of T1, T2, T3 and T4 were 11.93, 9.50, 13.93 and 36.47% (P <0.05), especially in the T4 group (p <0.05).

The contents of calcium (Ca) in control, T1, T2, T3 and T4 were 177.70, 267.38, 171.95, 211.97 and 178.42 ppm, respectively, which were higher than those of control by 50.47, 19.29 and 0.41% in T1, T3 and T4, respectively , Especially in T1 and T3 groups (p <0.05).

As can be seen from the above experimental results, the higher content of iron, sulfur and zinc was found with the increase of the legal sulfur content, which is effective to increase the content of iron, sulfur and zinc by feeding legal sulfur to Hanwoo steer . In addition, it is effective to increase calcium (Ca) content by feeding legal sulfur of 5g / day and 15g / day.

[Table 8] shows the results of experiments on heavy metal content in the fillet.

[Table 8]

As shown in Table 8, the mercury (Hg) content of Hanwoo steer according to the legal sulfur content was not detected in all treatments. The contents of As, As, T1, T2, T3 and T4 were 1.39, 0.56, 0.81, 0.59 and 0.53 ppm, respectively, (P <0.05), respectively.

The content of chromium (Cr) in the control, T1, T2, T3 and T4 were 1.53, 0.93, 1.38, 1.14 and 0.96ppm, respectively. T4, T2, T3 and T4 groups were lower than those of the control group at 4.06, 4.13, 4.29, 4.07 and 3.67ppm, respectively.

The Zn contents of the control, T1, T2, T3 and T4 were 5.16, 4.72, 5.51, 6.62 and 5.53 ppm, respectively, which were higher in the T3 group than the control group (p <0.05).

The contents of molybdenum (Mo) in the control, T1, T2, T3 and T4 were 0.32, 0.15, 0.19, 0.21 and 0.19 ppm, respectively. (P <0.05). In the control, T1, T2, T3 and T4 were 3.55, 3.55, 3.91, 3.58 and 2.96ppm, respectively.

In this experiment, the heavy metal content was lower than that of the control, and it is effective to reduce the heavy metal content by feeding legal sulfur to Hanwoo steer.

Table 9 shows the results of experiments on fatty acid composition of sirloin.

Table 9

As shown in Table 9, myristic acid in the fatty acid composition of the Hanwoo steers was 4.20, 3.35, 4.10, 3.80 and 3.10 in the control, T1, T2, T3 and T4 groups, %, Which was lower than that of the control group, and significantly lower than that of the control group (p <0.05).

In palmitic acid, the control, T1, T2, T3 and T4 were 29.70, 26.00, 27.25, 27.70 and 25.05%, respectively, which were lower than those of the control. , T2 and T4 (p <0.05), respectively.

Palmitoleic acid and stearic acid showed no statistically significant difference in the treatments.

The oleic acid, which is known to be a determinant of the taste of meat, was 46.40, 51.25, 48.95, 49.35 and 52.90% in the control, T1, T2, T3 and T4 (P <0.05). There was a statistically significant difference in the T1, T3 and T4 groups compared to the control group.

2.90, 2.90, 2.95, 2.65 and 2.45% in the control, T1, T2, T3 and T4 groups, respectively, compared with the control group. Inolenic acid was higher in the T2 group and lower in the T3 and T4 groups But no statistically significant difference was observed.

Linolenic acid showed higher tendency in the control group than in the control group, but it was 0.30, 0.50, 0.40, 0.35 and 0.45% in T1, T2, T3 and T4 groups, respectively, but statistically significant difference was not recognized .

The content of saturated fatty acid was 44.44, 40.49, 41.47, 42.07 and 38.06% in the control, T1, T2, T3 and T4 groups, respectively, (P <0.05), respectively.

Unsaturated fatty acid contents were 55.57, 59.52, 58.53, 57.93, and 61.94% in the control, T1, T2, T3 and T4 groups, respectively. (P <0.05), respectively.

On the other hand, mono-unsaturated fatty acid showed a statistically significant difference (p <0.05) in T1 and T4 groups compared to the control group, and that of polyunsaturated fatty acid was statistically significant It was not acknowledged.

From the above results, it was shown that saturated sulfuric acid content decreased and unsaturated fatty acid was increased by feeding legal sulfur, and oleic acid was higher in the case of the sulfur treatment than the control. Oleic acid is a monounsaturated fatty acid, which has a beneficial effect on geriatric diseases such as arteriosclerosis, because it causes a decrease in blood neutral fats and cholesterol when consumed in large amounts. In addition, when the content of oleic acid is high in relation to the taste of food, the taste of food is improved. Therefore, it is expected that 5 ~ 20g / day of legal sulfur is fed to Hanwoo steer to improve the taste and quality of Hanwoo beef.

[Table 10] shows the results of experiments on the amino acid content of the sirloin.

Table 10

As shown in Table 10, arginine in the amino acid composition of Hanwoo steers according to the legal sulfur content was 7.08, 7.06, 6.15, 6.45, And 6.02%, respectively. In the T1, T2, T3 and T4 groups fed with the legal sulfur,

In histidine, the control, T1, T2, T3 and T4 were 3.68, 3.45, 3.80, 3.47 and 3.52%, respectively, which were higher in the T2 group than in the control group and lower in the T1, T3 and T4 groups No statistically significant difference was recognized.

In the methionine and phenylalanine groups, T1, T2, T3 and T4 were 1.85, 2.46, 2.37, 2.20 and 1.85% respectively and 4.15, 4.50, 4.74, 4.39 and 4.18% , T2, T3, and T4, respectively. Especially, T1 was the highest among treatments.

In threonine, T1, T2, T3, and T4 were 5.22, 5.64, 4.92, 4.99, and 5.75%, respectively, in the control and T1 and T4 groups, respectively. , T2, T3 and T4 were 5.27, 4.58, 3.79, 3.92 and 5.99%, respectively (p <0.05) in the T2, T3 and T4 groups and higher in the T4 group than the control group It looked.

On the other hand, the non-essential amino acids alanine, aspartic acid, cystine, glutamic acid, glycine, proline, T1, T2, T3, and T4 were 6.65, 6.36, 6.29, 6.27, and 6.56%, respectively, in the control, alanine among the serine and tyrosine groups , But no statistically significant difference was observed. The aspartic acid contents of control, T1, T2, T3 and T4 were 9.62, 10.00, 11.43, 9.86 and 9.69%, respectively. (P <0.05). In contrast, the control, T1, T2, T3 and T4 were 0.82, 1.00, 1.13, 1.02 and 1.05% in cystine, respectively. In contrast, glutamic acid showed a tendency to lower in the treatment groups compared to the control group in the control, and the T1, T2, T3 and T4 groups were 16.63, 14.47, 14.80, 14.40 and 16.54%, respectively. Glycine, T1, T2, T3, and T4 were 4.18, 4.97, 4.79, 4.40, and 4.20%, respectively, in the treatment group, while the control, T1, T2, T3 and T4 groups in the proline were 4.25 and 4.69 , 4.14, 3.73 and 4.02%, respectively, which was higher in T1 than in the control. In serine, T1, T2, T3, and T4 were 4.16, 4.15, 4.67, 4.46, and 4.50%, respectively, which were higher in T2, T3, and T4 than in the control. Tyrosine The control, T1, T2, T3 and T4 were 3.28, 3.45, 3.69, 3.51 and 3.97%, respectively. The total essential amino acid contents of the control, T1, T2, T3 and T4 were 51.06, 51.76, 49.95, 53.17 and 50.30%, respectively. The non - essential amino acid contents of control, T1, T2, T3 and T4 were 48.94, 48.24, 50.05, 46.83 and 49.70%, respectively, which were lower in T1, T3 and T4 than control.

From the above results, it was found that the essential amino acid content was increased and the non - essential amino acid was decreased by feeding 15g / day of legal sulfur to the Hanwoo steer. Methionine and cystine contents of sulfur containg amino acid were higher than those of the control. The content of aspartic acid was higher in all treatments fed statutory sulfur (P <0.05). In this experiment, it is considered that the legal sulfur content will affect the sulfur - containing amino acid composition of the Hanwoo steers.

As can be seen from the above various experimental results, according to the present invention, it is possible to improve the growing ability (the amount of building intake, the average daily gain amount, the feed efficiency and the digestion absorption rate) by feeding the legal sulfur, (Iron), sulfur (S), zinc (Zn) and calcium (Ca) content in the conductor is increased to prevent anemia and improve shelf life, as well as remarkably improve the cross-sectional area and intramuscular fatigue (marbling score) , Functional beef which is capable of enhancing the immune function and enhancing the skeleton can be obtained as well as meat quality of the beef can be improved. The reduction of the heavy metal content of the conductor is advantageous in securing the hygienic and safety of the conductor, and increases the essential amino acid content of the conductor. The sulfur containg amino acids methionine and cystine, By improving the content, it becomes possible to provide flavor (flavor) unique to beef.
