Milk productivity of cows with the introduction of an organic concentrate based on poultry biowaste into the diet

This article reflects the results of the conducted experience related to the influence of an experimental organic concentrate based on dried bird droppings on the indicators of milk productivity of lactating cows. The research was conducted on the basis of the agricultural complex "Service Agro", located on the territory of the Republic of Tatarstan in the Arsky district. The experimental animals were cattle: 20 dairy cows of the Tatar type. To confirm the assumptions about the positive effect of the concentrate, it was proposed to divide the livestock into two equal groups: control and experimental. Paying attention to the scheme of the experiment, it can be said that both groups had the same food composition, however, the experimental group was given the considered additive of 0.5 kg / day per 1 cow. It was noted that the addition of organic concentrate in the indicated dosage does not affect the equilibrium nutrition, but, on the contrary, contributes to an increase in milk yield per day by 1.85 kg and reduces feed costs per kilogram of basic fat content: metabolic energy and crude protein in the ratio of 5.02 % and 2.57 %, respectively, due to the sufficiently high protein and mineral value of the studied feed the product.
