Veterinary-hygienic estimation of quality of quails eggs when using the food additive “PRINAROVSKAYA”

The aim of our research was to study changes in egg productivity (quality and number of eggs) of quail when including in their ration supplements of fodder of fish (DKR) “Prinarovskaya”, which is a dry, loose, uniform mass made from by-products of processing fish and fish products, as well as products of flour milling (wheat bran). It is obtained by grinding, cavitation heating and drying the resulting mixture. The resulting additive contains the following amino acids: alanine, arginine, aspartic acid, valine, his-tine, glycine, glutamic acid, isoleucine, leucine, lysine, methionine, serine, tyrosine, threonine, phenylalanine, cystine, as well as vitamins - B4, D3, E, and minerals: calcium - selenium, phosphorus and others. The experiment was carried out on quails of the Manchu breed at the age of 5-22 weeks. Prinarovskaya DKR was introduced into the ration per 100 g of the main diet (RR): 8 g of DKR into the experimental group, and only RR was fed to the quail of the control group - PK 1-1 compound feed. A veterinary and hygienic assessment of the quality of eggs from Quails Manchurian breed was carried out when feeding them with the main ration of the feed additive based on fish flour and wheat bran “Prinarovskaya”. In the course of the experiment, the following indicators were taken into account: the beginning of oviposition, the number of laid eggs, egg massometry, egg mass is an indicator of their nutritional qualities. In the existing GOST 31655-2012 “eggs turkeys, caesares, quails, ostrichs” eggs, as well as the requirements for quails hatching eggs, only the minimum weight of food and hatching eggs (10 g), below which it is not recommended to sell and incubate eggs [1]. We also took into account the following indicators that testify to the quality of eggs: large and small diameter of eggs, egg shape index, egg biochemical composition (amino acids: lysine, methionine, tryptophan; vitamins: A, B1, B2; minerals: calcium, selenium, phosphorus ; mass fraction of protein, mass fraction of fat, energy value of eggs) for quail of different groups. The study indicates the positive effect of the feed additive "Prinarovskaya" on the egg production of laying hens, morphological and chemical composition of eggs.
