PROBIOTIC TRILAKTOBAKT IN FEEDING OF QUAIL
06.00.00 Agricultural sciences
Description
During experiments on quail it was found that use of Trilaktobaktis probiotic is characterized with the activation of major types of metabolism, including protein –by increase the total protein content (5.17%) and mineral – by increase serum calcium and phosphorus (2.71 and 19.5%, respectively); by decrease of cholesterol content (10.6%). Probiotic stimulates erythro and hematopoiesis in quail: increase of the number of erythrocytes by 2.93% and hemoglobin by 2.57% was marked. Preparation enhances nonspecific resistance by increasing lysozyme and serum bactericidal activity by 47.4% and 149.6%.Besides, use of Trilaktobaktin diets increases digestibility of organic substance (5.74%), raw protein (3.95%) and raw fiber (4.83%). Probiotics use in the diet of quail improves nitrogen digestion by 5.3%, calcium and phosphorus – by 1.4%. Under the influence of probiotics content of lactic acid bacteria and bifidobacteriain chyme of quail increases by 46.2%.Use of Trilaktobaktin quail breeding increases safety and live weight gain by 6.0% and 6.9%, reduces the cost of feeds to produce 1 kg of body weight by 7.4%, and carcass yield reaches 66.4%, providing 100% output of first category carcasses. Use of Trilaktobakt feed additive has a positive effect on the quality of meat products. Thus, carcass output was 57.1% and the amount of fat decreased by 14.4% (pectoral muscles) and 12.7% (leg muscles) relative to the control. At the same time protein content in the thoracic and leg muscles increased by 7.5% and 10.7%
