The influence of the method of cultivation and feeding with the use of feed additives on meat productivity and the quality of quail products

The authors of the work conducted researches to study the influence of cellular and outdoor methods of keeping Texas breed quails, as well as feeding conditions with the use of a feed additive based on the biomass of the mushroom culture Cephaliophora tropica, saturated with useful trace elements and amino acids, on the parameters of preservation, growth, feed consumption, meat productivity, morphobiochemical blood data, as well as quality products of quail farming. The results of scientific and economic experiments demonstrated that, regardless of the method of poultry cultivation, the best data were obtained in groups whose diet included the feed additive under study. At the same time, the optimal condition for keeping quails to obtain the most positive results is the outdoor method. Thus, it was found that in this group of birds, the safety of quails was 94.0 %, the live weight on the 56 th day of the study was 405.81 g, which is 12.9 % higher than in the control group and 4.4 % compared to the experimental group of the same name, the conversion rate is lower by 3.7-9.3 %. It was revealed that the mushroom autolysate in the experimental groups had a positive effect on the morphological and biochemical parameters of the blood of the analyzed quails, since the stimulation of hematopoiesis was established, and protein metabolism in the body of birds was significantly enhanced. The highest rates of slaughter yield of the gutted carcass were recorded in the 2nd experimental group - 75.6 %, where quails were kept in the outdoor way using the feed additive Albit-Bio. When analyzing the quality of poultry meat, it was found that in quails of the experimental groups it was more complete, dietary and received the highest score according to the results of the tasting evaluation.
