Description

Poultry feed, method for increasing muscle and stomach weight of poultry, and method for raising poultry

The present invention relates to a feed for poultry, a method for increasing the muscle and stomach weight of poultry using the feed for poultry, and a method for raising poultry using the feed for poultry.

Chickens, which are representative examples of poultry, are divided into laying hens (eggs, layers) for laying eggs, broilers (broilers) for meat production, and Egg and chicken. Among them, the breeding stage of laying hens includes the rearing period (from 0 weeks to 18 weeks of age) when the chickens have grown to a state where they can lay eggs (egg-hens, adult chickens); After the laying hens have been raised for approximately 2 years, the use value is reduced due to the reduction in spawning rate, and each period of the spawning period until they are treated as broilers. Moreover, if the breeding period of laying hens is classified in more detail, it includes the young period (approximately 0 to 4 weeks of age), the middle period (approximately 4 to 10 weeks of age), and the large chick period ( (Approximately 10 weeks to 18 weeks).

However, in order to give full play to the chicken's spawning ability during the spawning period, it is of course important to properly control the feed or environmental factors provided to the chickens during the spawning period, but this is not sufficient. That is, the ovaries and oviducts of chickens grow from the late breeding stage to the beginning of spawning. As a result, the chicken's egg laying ability is improved. However, due to the physiological pressure caused by the growth of ovarian and oviducts, the chicken's food intake (feed intake) It may stagnate, and there may be adverse effects such as a decrease in initial egg weight or a longer period required to reach the peak of egg production. In order to prevent this, it is important to improve the feedability of chickens from the late breeding period to the peak spawning period, and to ensure that the feed intake is sufficient to meet the nutritional requirements required for continued spawning. Therefore, it is beneficial to The rearing period before the spawning period causes the digestive tract, especially the stomach, to grow and enlarge in the chicken, and increases its volume in advance.

The muscular stomach is one of the digestive organs of poultry represented by chickens, also known as the forelimb, and the glandular stomach that secretes gastric juice together constitutes the stomach of poultry. The feed mixed with gastric acid and digestive enzymes in the glandular stomach is sent to the muscular stomach, which is a bag-shaped organ that includes a thick layer of muscle. The muscular stomach shrinks and digests, and is digested and absorbed below the duodenum. In addition, coarse grains (gravel) eaten by poultry are stored in the muscle stomach, and the feed is broken and ground as the muscle stomach contracts and relaxes to promote digestion. In the state of containing coarse grains, the muscle stomach will more actively perform contraction and relaxation exercises, so that the muscle stomach will increase its weight and grow larger, which can improve digestion and increase the feed intake of poultry.

However, in the current breeding environment of the industry, only general compound feed is supplied. During this period, poultry cannot accumulate coarse grains in the muscle and stomach, and the increase in muscle and stomach weight is not sufficient. It is important to address the situation. Growing the muscle and stomach to increase the feed intake is important not only for the laying hens described above, but also for broilers, which are another main use of chickens.

Meat chicken is a general term for chickens raised for food purposes. Broiler chickens also include chickens called "native chickens", which are raised for the purpose of producing delicious or chewy meat. After hatching for a long period of about 12 to 17 weeks, they are usually called Broiler chickens refer to broiler chickens (broilers) that are raised to grow to a weight of 2.5 kg to 3.5 kg within a period of 6 to 8 weeks after hatching, and are then shipped for food purposes. For meat chickens, the edible parts involve multiple parts, not only skeletal muscles such as leg meat, shoulder meat, chicken wings, chicken breasts, chicken neck, etc., but also the heart, liver, kidneys, or the stomach (肫), etc. Internal organs can also be eaten. The broiler chickens start moulting in the pre-feeding period from about 3 weeks of age to hatching, and the growth rate is accelerated. By providing appropriate feed during this pre-feeding period, the weight and growth of the muscle and stomach are increased, and the post-feeding period (3 weeks of age) In the future, the amount of feed is increased, so that it can be expected to obtain a better performance of gaining weight, and to obtain a higher value and more muscular stomach.

According to the situation as described above, in order to avoid the physiological pressure from the self-breeding to the early spawning period of poultry, such as chickens, as a representative example, to adversely affect the egg weight or the peak period of spawning, or to obtain more meat or offal from the poultry. It is expected to develop a feed for poultry that can efficiently increase the weight of the muscle and stomach of poultry. Regarding the problems of promoting the growth of poultry muscles and stomachs and improving breeding performance, it is known to mix 0.5 to 10 parts by weight of pulverized food with 100 parts by weight of the feed before corn-cob meal preparation. The corn ear meal for poultry feed (Patent Document 1); 0.1 to 10 parts by weight of rice husks, buckwheat husks, and wheat husks are prepared from grains with respect to 100 parts by weight of the feed before preparation. Feed for shelled poultry (Patent Document 2). In addition, as a person for promoting the growth and development of the muscles and stomachs of poultry, it is known to formulate poultry feed for ceramics with alumina purity of 99% or more and hardness of at least 70 kg (patented) Reference 3).

[Problems to be Solved by the Invention] However, although the inventions of Patent Document 1 and Patent Document 2 have the effect of improving the dressing, the muscle and stomach enlargement effect of poultry is not sufficient. In addition, in the invention of Patent Document 3, the contents of the muscle and stomach are used instead of coarse particles (gravel). Therefore, after sintering and coarsely pulverizing alumina powder having a purity of 99% or more, it is necessary to appropriately adjust the poultry cycle. The particle size is added to the feed, and there is a concern that the operation becomes complicated.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a muscle and stomach weight of poultry that can be efficiently raised in the rearing period and the pre-breeding period, and that the feed intake and feed intake of the poultry in the early-spawning and pre-feeding period can be increased. Amount of feed for poultry, a method for increasing the muscle and stomach weight of poultry, and a method for raising poultry. [Means for solving problems]

The present inventors have conducted diligent research in order to solve the above-mentioned problems, and as a result, have found that if a feed containing a specific cellulosic raw material is supplied to an egg-laying poultry or a pre-breeding meat poultry during the rearing period, it can be efficiently increased The weight of the muscle and stomach can increase the feed intake and feed intake of spawning poultry in the early spawning period and meat poultry in the late rearing period.

Moreover, the invention of this application is characterized by the following points. A feed for poultry, wherein the fiber raw material is prepared in an amount of 0.1 to 5 parts by mass relative to 100 parts by mass of the feed before the fiber raw material is prepared. 2. A feed for poultry, wherein the fibrous raw material is selected from the group consisting of buckwheat husks, rice husks, oats, sunflower seeds, pine nut husks, palm kernel husks, hay cubes, mixed hay pellets, walnut shells, Jujube group. 3. A feed for poultry, in which a fibrous raw material is prepared in such a way as to exert an effect of increasing the weight of the muscle and stomach of poultry. 4.

A method for raising poultry, which comprises feeding the poultry feed. [Effect of the invention]

According to the present invention, by providing a feed containing a specific cellulosic material to a spawning poultry or a pre-breeding meat poultry, the muscle and stomach weight can be efficiently increased, and as a result, the spawning in the early spawning period can be achieved. Feed intake and feed intake of poultry for eggs or meat are increased.

The fibrous raw materials prepared in the feed of the present invention can be selected from buckwheat husks, rice husks, oats, sunflower seeds, pine husks, palm kernel husks, hay blocks, mixed hay kernels, walnut husks, and jujube kernels. These cellulosic raw materials can also be used in combination with two or more kinds in the feed.

(Explanation of fibrous raw materials) Buckwheat hull: A shell remaining after removing the endosperm portion from the harvested buckwheat seeds. Rice husk: The rind remaining after the rice is removed from the rice. Oats: The seeds of the annual plant oats of the genus Poaceae. Sunflower seed: The seed of an annual plant in the family Asteraceae. Pine nut shell: A shell that remains after the endosperm portion has been removed from the seeds of the Pinaceae pine plant. Palm kernel shell: The outer skin of the seed of the coco palm oil palm. Hay block: Dry grass, such as alfalfa hay, which is used as feed for dairy cows, chopped, compressed, and shaped into a rectangular parallelepiped shape with a side of 2 cm to 5 cm. Mixed hay kernels: Dry and pulverize various forages such as alfalfa hay, which are used as feed for dairy cattle, and shape them into cylindrical particles with a diameter of about 6 mm. Walnut hull: The outer skin after the internal seeds (kernels) have been removed from the stone fruit of the walnut family Juglans. Jujube: Seeds of the small tree of the genus Rhamnuaceae. Jujube can be crushed to use only the shell, or the whole crushed product including the shell can be used directly.

Daily, general adult chicken feed (CP17%, ME2850 kcal / kg) is 57 days from 119 days to 175 days, and the water supply is continuous. Moreover, the particle size of the palm kernel shell is 1.0 mm to 4.0 mm.

For each test chicken, the muscle and stomach weight (g / head), muscle and stomach weight ratio (%), weight gain (g / head), feed requirement rate, spawning rate, and egg weight (g) were obtained. The test results are shown in [Schedule 9], [Schedule 10], and [Schedule 11]. As shown below, compared to the control area, the muscle and stomach weight and developmental performance of the chickens in the test area were confirmed. Excellent. By supplying palm kernel shells to the young and old chicks (42-119 days old) of laying hens (Julia species), their respective muscle and stomach weights were confirmed to have increased. In addition, by supplying palm kernel hulls to the middle and young chicks, the developmental performance at the rearing stage, that is, the growth rate and the feed requirement rate can be improved. Furthermore, it was confirmed that by supplying palm kernel shells (fibrous raw materials), the weight of the muscle and stomach was increased, thereby increasing the food intake at the early stage of spawning, and improving the spawning rate and egg weight. Based on the results of the above tests, the effectiveness of the feed of the present invention was confirmed.

Test Example 5 The effect confirmation test of supplying palm kernel shells using another type of laying hens in the middle and old brooding periods (43 to 119 days) was obtained by laying hens (Julia species). The supply of palm kernel hulls during the growing period improved the performance of the breeding stage and the performance of the early spawning, and evaluated the performance of another chicken breed (Boris brown). 128 broiler hens and large broilers using Boris brown (control zone: 8 / zone × 6 repeated, palm kernel shell 1%: 8 / zone × 6 repeated, palm kernel shell 0.5%: 8 / Zone × 4 repeated), for the three zones of the control zone, palm kernel shell 1%, palm kernel shell 0.5%, the feed prepared as described in [Annex Table 12] is continuously supplied. The method for preparing the palm kernel shell is the same as in Test Example 4. Regarding the supply period, middle-aged feed (CP17%, ME2800 kcal / kg) is 28 days from 43 days to 70 days old, and large-aged feed (CP14%, ME2750 kcal / kg) is 50 days from 70 days to 119 days old Daily, general adult chicken feed (CP17%, ME2850 kcal / kg) is 57 days from 119 days to 175 days, and the water supply is continuous. Moreover, the particle size of the palm kernel shell is 1.0 mm to 4.0 mm.

For each test chicken, the weight gain (g / head), feed requirement rate, spawning rate, and egg weight (g) were obtained. The test results are shown in [Attached Table 13] and [Attached Table 14], and as shown below, it was confirmed that the chickens in the test area were superior in weight gain, development performance, and the like compared to the control area. By supplying palm kernel shells to the middle and large chicks of the laying hens (Boris brown species), the developmental performance at the rearing stage, that is, the increase in body weight and feed requirements, can be improved. In addition, it was confirmed that by supplying palm kernel shells (fibrous raw materials), the weight of the muscle and stomach was increased, thereby increasing the food intake in the early spawning period, and improving the spawning rate and egg weight. Furthermore, it was confirmed that as the weight of the muscle and stomach increased due to the supply of palm kernel shells in the rearing period, feed intake at the early stage of spawning, spawning rate, and egg weight were not improved in relation to the breed of chicken. Based on the results of the above tests, the effectiveness of the feed of the present invention was confirmed. In addition, the muscle and stomach increasing effect of the palm kernel shell can be confirmed in Test Example 1 to Test Example 4, so no anatomical examination was performed.

Test Example 6 Confirmation of the Effect of Supplying Palm Kernel Shells Using Broiler Chickens in the Early Breeding Period (7 to 17 Days of Age) 240 Chunky Breeders (Males) (Control Area: 40 / Area × 3 Repeat, Palm Kernel shell 1%: 40 pieces / zone × 3 repeated), for the control zone and palm kernel shell 1%, the two zones are continuously supplied with the feed prepared as described in [Annex Table 15]. Furthermore, regarding the adjustment of palm kernel hulls, palm kernel hulls were used as the fibrous raw material and screened, (1) the size of 1.0 mm to 2.47 mm was selected, and (2) the Nara-type free crusher (5 mm (Mesh, 2,500 revolutions) pulverize coarse particles with a particle size of 2.47 mm or more, use a sieve to separate the particles with a particle size of 1.0 mm to 2.47 mm, (3) mix and stir (1) + (2), and use the internal proportions 1.00% by mass was formulated into a basic feed, and pellet crumble processing was performed on it to prepare a pre-feeder for chicken. The volume specific gravity (g / L) of the palm kernel shell used was 684.60 ± 1.65. Regarding the supply period, the control area: pre-crushed feed (CP23%, ME3100 kcal / kg), palm kernel shell 1% area: pre-crushed feed (CP23%, ME3100 kcal / kg) was set to 7 days to 17 days. On the 11th, the supply of water was continuous. Moreover, the particle size of the palm kernel shell is 1.0 mm to 2.47 mm. For the following periods other than the above, the control area and the palm kernel 1% area were supplied with the same feed. 0 days to 7 days: universal feeding of broken feed (CP25%, ME3000 kcal / kg) 17 days to 28 days of age: universal late meal feed (CP19%, ME3280 kcal / kg) 28 days to 38 days of age: General Processing Powder & Pellet Feed (CP18%, ME3300 kcal / kg)

For each test chicken, the muscle weight (g / head), muscle weight ratio (%), weight gain (g / head), and feed requirement rate were determined. The test results are shown in [Attached Table 16] and [Attached Table 17]. As shown below, it was confirmed that the chickens in the test area had superior muscle and stomach weights, developmental performance, and the like as compared to the control area. By supplying palm kernel shells to broiler chickens (male broilers) at the early stage (7 to 17 days of age), it was confirmed that the weight of the muscle and stomach increased, and the effect was maintained until shipment. In addition, it was confirmed that the supply of palm kernel hulls in the early stage of breeding can improve the shipping performance, that is, the increase in body weight and feed requirements. Furthermore, it was confirmed that the supply of palm kernel shells (fibrous raw materials) increases the weight of the muscle and stomach, thereby improving development throughout the fattening period. In addition, it is thought that by increasing the weight of the stomach and muscles in the early stage of feeding, the availability of nutrients is improved. Based on the results of the above tests, the effectiveness of the feed of the present invention was confirmed.
