The use of biostimulants for "resuscitation" of quail embryos

Abstract

Today, quail farming is one of the most intensively developing branches of agriculture, which is associated with the possibility of producing this subsector of dietary products: meat and eggs. In this regard, increasing the growth rate of quail breeding through the use of new science-intensive and environmentally friendly methods becomes an urgent task. At the same time, as you know, the success of production largely depends on the work of the hatchery. The developed method of stimulating the embryonic development of quails is an effective and interesting direction in this matter. The use of biostimulants at the early stage of ontogenesis, in embryogenesis, contributed to a decrease in the amount of incubation waste and an improvement in metabolism. Thus, the preincubation treatment of Japanese quail eggs with a composition consisting of colamine, succinic acid, serine and vitamin B6 made it possible to increase the viability of embryos, as well as optimize metabolic processes in the body and increase the level of nonspecific resistance. In particular, the hatching of quails in the experimental batch exceeded the control by 15.19% (p <0.001), and the hatchability of eggs - by 10.48% (p <0.001), the mass of the yolk sac with residual yolk in the experiment was significantly lower by 2 times. Also, the content of total protein in the blood serum of quails of the experimental group increased by 18% (p <0.05), albumin - by 5.5% of the activity of а-amylase by 6.9% (p <0.05), glucose - by 3.4%, there was a decrease in LDH activity by 1.3 times and a decrease in lactate content - by 5.1% relative to the control, while BaSk increased by 3.8% (p <0.05), lyso-zyme - by 6, 4% (p <0.05).
