FEEDING OF DOMESTIC BREEDED BULLS WITH PROTEIN-RICH GRANULAR FEED PRODUCT MADE FROM "WALNUT, CLOVER, AMARANTH" PRODUCTS.

This industry provides 97% of the world's milk demand, and 50% of its meat demand. This indicator corresponds to 99% and 65% in Uzbekistan, respectively. Bulls need to be properly fed to gain high weight. Most farmers distribute the feed three times at the same time interval. From the postpartum period to 60 days, calves are fed milk, then wheat groats and quality hay are added. Such feeding promotes rapid growth and eliminates problems with the digestive system. From 60 to 90 days, feed products with a high protein content, which help to increase body mass, are the basis of the diet, preference is given. This includes vegetable crops, ground grain. From 120 days, an additional 10-15 kg of soaked green grass is given. Professor P. N. Kuleshov (1949) stated that the amount and quality of feed given to certain types of animals is also important. The development of rapid growth and fat accumulation creates a carnivorous animal. In order to produce cheap beef, calves should be intensively fed during the first 6-8 months of their life. Even now, the role of feeding in the improvement of breeds of agricultural animals of various types, in the creation of new systems and types of them, productive herds, in revealing the effectiveness of crossbreeding, has been determined in the results of scientific production studies conducted in various ecological regions. According to V. Kalashnikov, Kh. Amerkhanov (2005), N. I. Strekozov, G. P. Legoshin (2005), Yu. Kotlyarov, N. Klunduk (2005) and others, full value feeding of cattle increases their genetic potential for productivity is an important factor in the output. Similar conclusions were made by K.K. Karibaev (1999), A. Kharlamov, A. Irsultanov (2001), N.I. Ivanova (2004) also came. 57 Acumen: International Journal of Multidisciplinary Research Acumen: International Journal of Multidisciplinary Research Volume 1, Issue 2 Sh.A. Akmalkhanov (1993), U. Nosirov (1974, 2000), M. Ashirov (1994), K. Karibaev (1996), L.K. Ernst (2001), A.V. According to Cherekaev (2001), Kh. Amerkhanov (2004) and other well-known scientists, the milk yield of feed cattle is 60-70% and the meat yield is 60-62% depending on feeding, its level and total cost. It is clear from these points that feeding is the main factor in bringing out economic beneficial characteristics of cattle In the research of S.S. Ibragimov (1991), it was found that growing Bushuev and Holsteinized black-Ola calves under conditions of full-value feeding allowed them to increase their live weight by 13-14 times from birth to 18 months, and they gained 7.25-7.25 per 1 kg of live weight. He stated that he spent 7.55 kg of food There are many factors that influence the full development of the genetic potential of bulls fed to the fattening area in terms of meat production. The main and most important of these is to feed them with full value. In our experiment on Holstein bulls at the farm "Tashpolatov Bahadir Zhoraniyozovich" in Sherabod district, we obtained the following results when we fed them with granulated feed made from "Yantok, beda, amaranth" products, rich in oxygen. It should be noted that protein is one of the most important substances involved in the formation of new tissues and organs in the growing body of bulls. As the age of animals increases, the consumption of protein per living unit decreases. If the amount of protein in the diet is insufficient, the nutrients are not fully consumed, as a result, growth and development are slowed down. It has been found that when the amount of protein exceeds the norm, the appetite of animals deteriorates and growth lags behind. The reason for this is that most of the nitrogen is excreted in feces and urine. In this case, the amount of protein in the live weight increases, while fat decreases. In order to prevent such negative consequences, we paid special attention to the amount of digestible protein when feeding animals. For this, we can learn from our experience 58 Acumen: International Journal of Multidisciplinary Research Acumen: International Journal of Multidisciplinary Research Volume 1, Issue 2 Feed consumed by bulls during the experiment is kg (average per head) Table 1. № Foods and their Amount of food given to bulls (6 months). nutrition Amoun fo t o k o d g f i n F e e d u n i t k g T o t al f o o d u n i t k g A E M f at g K l e c h at k a g P r o t ei n g D r y m at t e r g C a g P g 1 Milk 4 0.30 1.2 200 148 - 132 520 4.8 5.3 2 Blue clover 3 0.21 0.63 333 24 243 120 840 14.1 0.21 3 Senej 2 0.35 0.70 296 68 254 142 900 22 2.0 4 Alfalfa hay 2 0.44 0.88 660 44 506 202 1660 34 4.4 5 "Yantok, 3 1.0 3.0 alfalfa" granulated fodder product 6 Table salt Total 6.41 1489 284 1003 596 3886 74.9 11.91 The amount of digested protein in the actual consumer product of the bull experiment was 460.6 kg, 116 grams of digested protein per 11 kg volume unit.
