Premixes and protein vitamin-mineral concentrates in livestock and poultry breeding: Technological properties

It is known that today in the field of feeding animals and poultry, the use of dietary supplements, or premixes, is relevant. However, it should be noted that the premix quality mainly depends on the filler. Due to the above, the authors have performed comprehensive studies of the possibility to use fodder concentrate and the Sarepta vegetable raw material as a filler in the composition of premixes for cattle and poultry diets. In studying the nutritional value and the technological properties, the new filler was favorably different from the one traditionally used (sunflower meal). In the course of the research of using premixes and protein vitamin-mineral concentrates with the new filler in the composition of the fodder for agricultural animals and poultry, the following positive results were obtained: during the main period of experiment, milk yield of the dairy cows increased by 7.40 %; milk quality also improved, the value of byproducts from a single animal amounted to 4,928 rubles; the live weight of the dairy calves increased by the age of six months by 1.7 %, which amounted to 7,560 rubles of additional growth; during the period of experiment, egg productivity of the laying hens increased by up to 1.73 %, and the economic effect was 1,142.73 rubles; the live weight of the broiler chickens increased by 10.2 %, the slaughter yield of carcasses increased by 1.9 %, with that, the additional profit per animal was about 55.51 rubles. Based on the comprehensive research, one can recommend introducing the premix with the Sarepta concentrate to the diets of cattle and poultry to increase their productivity, improving product quality and economic efficiency of the livestock breeding industry and poultry production.
