В статье приводятся показатели, характеризующие рост и уровень мясной продуктивности бычков черно-пестрой породы при скармливании им люцернового сенажа, заготовленного с разной дозировкой биозакваски на основе пропионовокислых бактерий. Препарат вводили в процессе закладки сенажа в виде рабочего раствора в количестве 2, 4 и 6 л на 1 т консервируемой массы. Опыт проводился в условиях Республики Башкортостан. Для этого 40 10-месячных бычков разделили на 4 группы. Молодняк контрольной группы получал неконсервированный сенаж, а опытных групп — сенаж, с закваской на основе пропионовокислых бактерий в указанных выше дозах. Установлено, что молодняк опытных групп лучше рос и развивался. В 12 мес его живая масса была выше, чем в контрольной группе на 2,50—6,10 кг (0,73—1,77%); в 15 мес — на 9,34—15,14 кг (2,20—3,57%; Р<0,05); в 18 мес — на 15,51—23,31 кг (2,10—4,66%; Р<0,05—0,01). Более высокая энергия роста молодняка опытных групп при откорме на рационах, включающих консервированный сенаж, способствовала и более высоким убойным показателям. Наилучший эффект проявился у бычков, потребляющих сенаж с закваской на основе пропионовокислых бактерий в дозе 4 л рабочего раствора на 1 т зеленой массы. Данная дозировка обеспечивает увеличение массы парной туши на 12,9 кг (4,79%),The article presents the indicators characterizing the growth and level of meat productivity of bull-calves of the black-and-white breed, when they are fed alfalfa haylage, harvested with different dosages of biosakvaski based on propionic acid bacteria. The drug was administered in the process of laying haylage in the form of a working solution in the amount of 2, 4 and 6 liters per 1 ton of preserved mass. The experiment was conducted in the conditions of the Republic of Bashkortostan (Alga, collective farm, Chekmagushevsky district). For this 10-month gobies were divided into 4 groups. The young of the control group did not receive canned haylage, but the test groups received haylage, with sour based on propionic acid bacteria in the above doses. It was found that the young of the experimental groups grew and developed better. So at 12 months of age, their live weight was higher than in the control by 2.50—6.10 kg (0.73—1,77%); in 15 months — by 9,34—15,14 kg (2,20—3,57%; P<0,05); in 18 months — by 15,51—23,31 kg (2,10—4,66%; P<0,05—0,01). The higher growth energy of the young of the experimental groups during fattening on rations, including canned haylage, contributed to a higher slaughter rate. The best effect was manifested in calves consuming haylage with ferment based on propionic acid bacteria in a dose of 4 liters of working solution per 1 ton of green mass.This dosage provides an increase in the mass of steam carcass by 12,9 kg (4,79%), carcass output by 1,0%; slaughter weight — by 14,0 kg (4,95%; P<0,05); slaughter yield — by 1,2%.

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

Increasing the protein nutritional value of rations through the use of legume-grass crops, press-cakes and oil-cakes, complete provision of high-quality animal feed, balanced in protein and other components, is the leading direction of solving the protein problem in animal husbandry and remains an urgent topic for research. The purpose of the research was to study the use of hay and haylage from the mixture of Eastern galega and awnless brome in the rations of first-calf heifers instead of the same feed from the mixture of alfalfa and awnless brome. For carrying out scientific and economic experiments in LLC Kushul in the Dyurtyulinsky district in the Republic of Bashkortostan on the principle of pairs-analogs (breed, live weight, age, level of productivity) four groups of first-calf heifers of Black-and-White breed per 10 heads in each have been selected. The inclusion of 4 kg of hay and 10 kg of haylage in the rations of first-calf heifers of the mixture of Eastern galega and awnless brome has a positive effect on increasing the protein content in milk by 3,1 and 3,4 %, sugar by 0,6 and 0,9 abs.%. There was a steady increase in the milk of cows of the experimental groups: carotene, total calcium and inorganic phosphorus compared to the control group where the animals received 4 kg of hay and 10 kg of haylage of the mixture of alfalfa and awnless brome. Thus, studies have shown that the use in rations of first-calf heifers hay and haylage of mixtures of Eastern galega and awnless brome promotes not only productivity, but also improve milk quality.

This paper presents the results of studying the conversion of feed into nutrients in the carcass of bulls during the fattening of young Kalmyk breed in the conditions of Yakutia. The studies were carried out on the basis of the Soloosun agricultural production complex, Megino-Kangalassky region. The experiment was organized on Kalmyk bull-calves fed from 15 to 18 months of age. There were formed 2 groups of 25 bulls analogs: the control and the experimental one. The animals of the control group were fed according to the ration adopted on the farm. The diet of the animals from the experimental group included 200 g of Hongurin zeolite and 45 g of Kempendyai salt per animal. The main ration of animals by structure consisted of meadow hay 46%, haylage – 22% and compound feed 32% or 12.57 EFU per day. At the beginning of the experiment, the live weight of the animals was almost identical. At the end of fattening, the bulls of the experimental group in live weight exceeded the animals of the control group by 10.9 kg. Consequently, the experienced bulls had higher bioconversion rates, which was reflected in an increase in the meat productivity of animals. The analysis showed that the control group of bulls was inferior to the experimental group in terms of pulp by 11 kg., In the deposition of food protein by 1.3 kg. The calculation of the data on the conversion of protein into food protein showed that in the control group this indicator is 5%, and in the experimental group it was 6.2%. The yield of dietary protein in the control group was 40.4 g, in the experimental group – 52.8 g. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Hongurin zeolite and Kempendyai salt, had a higher ability to transfer nutrients and feed energy into meat products. The indicators of economic efficiency per 100 heads of fattening bulls of the Kalmyk breed are: profitability – 122.53%, cost price 1132 thousand rubles, profit – 1,388 thousand rubles, profit – 1.23 rubles per 1 ruble costs. The efficiency of beef production at a specialized feedlot increases by 22.53%.
