Feed additive for Korean native cattle and method of breeding native cattle using the same}

The present invention relates to a feed additive for Korean cattle for improvement of meat quantity/meat quality and short-term fattening, and a method for fattening Korean cattle castrate using the same.

As the perception of castration and extension of the fattening period, which are typical breeding management techniques for improving the quality of Korean beef, has become common, these breeding techniques are being practiced in castrated Korean beef farms.

Currently, through the improvement of Korean beef, the shipment weight has increased significantly compared to the past, and the intramuscular fat has also improved a lot. In general, in 2011, the appearance rate of grade 1 or higher was 78.3%, the carcase weight was 381.6 kg, the back fat thickness was 12.5 mm, and the loin cross-sectional area was 84.7 cm ² . , the thickness of the back fat increased to 13.8 mm and the cross-sectional area of the loin to 95.0 cm ² (APGS, 2019). For this reason, the average age of shipment for most castrations in Korea is 30.5 months in 2019.

Recently, feed additives such as probiotics, vitamins, and enzyme buffers are being used to further increase the shipment weight and intramuscular fat, but their availability is low and the shipment weight or intramuscular fat content tends to be low due to early shipment when the feed cost rises and the meat price falls. represents

Therefore, it is necessary to change the feed feeding system for each growth stage to increase the shipping weight and shorten the shipping age, so that it is necessary to build a feed feeding system according to each growth stage along with the feeding of meat quantity/meat quality improvement additives that can reach 700-750 kg in a short time. there is

The present invention relates to a feed additive for Korean cattle, comprising lysine, methionine, protected fat, sugar, yeast culture, vitamin C, corn dipping, protein skin and soybean meal.

The feed composition is preferably lysine 3-4% by weight, methionine 3-4% by weight, protective fat 10-20% by weight, sugar 10-20% by weight, yeast culture 10-20% by weight, vitamin C 1-3 It is characterized in that it contains 10 to 20% by weight of corn distillate, 10 to 20% by weight of protein skin, and 10 to 20% by weight of soybean meal.

The feed additive has the effect of increasing the intramuscular fat and the sirloin cross-sectional area for improvement of meat quantity or meat quality and short-term fattening, and is characterized in that it reduces the thickness of back fat.

The present invention also relates to a method for fattening Korean cattle, preferably castrated Korean cattle, using the feed additive.

The fattening method is, first, as a feed for the growing season, a feed having a total amount of digestible nutrients (TDN) of 69.5 to 71% by weight and a crude protein content (CP) of 13 to 14.5% by weight, as a feed before fattening, a total amount of digestible nutrients (TDN) of 69.5 to 71% by weight, crude protein content (CP) of 13 to 14.5% by weight, and total digestible nutrients (TDN) of 70 to 72% by weight and crude protein content (CP) of 12 to 14% by weight % of feed, pre-finishing feed, post-finishing feed, with total digestible nutrients (TDN) of 72 to 74 wt% and crude protein content (CP) of 11 to 13 wt%, total digestible nutrients ( TDN) of 72~74% by weight and crude protein content (CP) of 11~13% by weight are prepared.

Then, at the age of 6 to 9 months of age, the feed for the growing stage is supplied, at the age of 10 to 16 months, the feed and the pre-finishing feed are mixed and supplied in the same weight, and at the age of 17 to 22 months, the pre-finishing feed is supplied, and at the age of 23 to 27 months. It is characterized in that the feed additive is supplied from the age of 10 months of the growing season to the age of 27 months before shipment while supplying the feed for the late fattening period. In the present invention, such a feed supply period is referred to as the early growing season, the late growing season, the fattening period, and the fattening period.

Korean cattle raised up to 27 months are shipped for slaughter, and it is appropriate to maintain a weight of 720 to 750 kg at the time of shipment.

The feed additive is preferably supplied at 40-50 g/day.

In the fattening method, hay or rice straw may be supplied together with the feed as roughage, and it is preferable to additionally supply a mineral block containing salt, calcium, phosphorus, and vitamins.

In the conventional castration method, the feed for the growing and non-bringing period is replaced at the beginning of 14 months, and the intermediate mixed feed stage is not distinguished. In addition, in such a fattening method, the period of shipment after finishing the feed supply in the late fattening period is 31.5 months, which serves to reduce the appropriate shipment time through the use of the feed additive and the fattening method of the present invention.

The present invention relates to a feed additive for Korean cattle comprising lysine, methionine, protected fat, sugar, yeast culture, vitamin C, corn lees, protein skin and soybean meal, wherein the feed additive is used before and after the growing season, before and after the fattening period and fattening It provides a cattle method with high quality meat while shortening the total period of breeding and finishing seasons by additionally supplying during late feed supply.

Example 1. Confirmation of weight gain until the pre-fading period

In order to determine the addition amount of each raw material including amino acids (lysine, methionine), 4 Korean beef cattle were disclosed for each group, and the total and daily weight gain from 6 months of age to 16 months of age was compared.

For this, each feed additive was supplied to the experimental group, and only the yeast fermented product was supplied to the control group among the feed additives. Feed additives were fed 50g per day during the test period.

When confirming the results of Table 3, in particular, the content of the limiting amino acids lysine and methionine was found to significantly increase the weight gain when at least 3% by weight in the feed additive, 3% by weight and 5% by weight did not differ significantly. Therefore, it was determined that the limiting amino acid in the feed additive may be added in an amount of 3 wt% or more and less than 5 wt%.

Example 2. Confirmation of weight gain within the entire fattening period

In addition, each new experimental group was established to reconfirm the weight gain and feed requirement of the geese during 6 to 27 months for the entire fattening period. At this time, as for the fattening period, the non-experimental group was bred according to the existing fattening period [growth period (6-12 months old), pre-fading period (13-22 months old), late fattening period (23-27 months old)], starting with the control group, each feed additive According to the method of the present invention, the treatment group is divided into the first half of the growing season (6-9 months old), the second half of the growing phase (10-16 months old), the pre-finishing phase (17-22 months old), and the late fattening period (23-27 months old), From the second half, 50g/day was added to each feed and fed. For the feed for each period, the standard feed used for grading livestock products was used, and for the feed at the end of the growing season, a mixture of the feed for the growing stage and the feed for the pre-finishing period was used at the same weight. Feed was fed twice a day at 09:00 am and 16:00 pm, and water and rinkal block were vegan. In the case of the control group, only yeast fermented products were fed 50 g per day as live cells, and each individual feed additive was fed by top dressing at 50 g/day when feeding in the morning.

For the study of growth performance, the weight of the test shaft was measured using an electronic scale for measuring cattle weight at 10:00 before feeding in the morning once a month. The results are shown in Table 4 below.
