Chelate complexes of microelements in mixed fodder for quails
The results of research on the introduction of trace elements of chelate complexes (cobalt, zinc, iron, manganese, copper) with green tea tea and L-asparaginates into the Japanese quail’s diet are introduced with a 10 and 20 fold decrease in their input rate. It is established that such diets contribute to the acceleration of bird growth, increase safety and productivity. The use of green tea and L-asparaginate gallocatechins with a decrease in the input of trace elements (by 10 and 20 times) when preparing mixed fodders did not adversely affect the macro-microelement and amino acid composition of quail meat. At the same time, the protein quality index of meat was higher in chickens-quails of II and III experimental groups relative to the I control group by 15.61% and 12.43%, respectively. The increase in egg laying on the laying hen during the egg-laying period was observed in the II and III-experimental groups by 4.12-5.34%, with the weight of one egg 11.70-11.75 g, the yield of egg mass at 5.02-5.79 % in comparison with 1 - control group. The intensity of oviposition was 72% in the 1-control group, 75% in the experimental group, and 76% in the experimental group. The best hatchery qualities were the eggs of layers of experimental groups. The yield of hatching eggs in the first control group was 80.00%, in the second test group - 83.52%, in the experimental group - 85.39. The withdrawal of chickens in the II and III experimental groups was from the fertilized eggs - 93.24-93.33%, thereby exceeding the control by -5.19-5.28%, respectively. Decrease in the level of input of chelating complexes of trace elements with green tea tea cachets in 10 and L-asparagines 20 times in the mixed feed did not adversely affect the development of embryos during the incubation period
