Abstract
The results of the experiment on the use of fractionated protein-vitamin wheat bran flour (pure and mixed with enzyme preparation produced under Feedbest® trade mark) with particle size 140 microns in the ration of growing quails are presented. The experiment lasting 60 days was conducted according to the generally accepted methodology on quails of the Japanese breed. For the experiment, three similar groups of 80 birds each (one control and two experimental) were formed at one day of age. All groups received a basic diet prepared taking into account the age and physiological characteristics of quails. In the diet of young animals of the 1st and 2nd experimental groups a part of wheat (7%) mixed fodder was replaced by wheat protein-vitamin flour (particle size 140 microns). The quails of the 2nd experimental group were fed protein-vitamin meal with the enzyme preparation Feedbest® P5000 GT designed to increase the bioavailability of phosphorus, mineral elements and amino acids from components of feed for poultry and pigs. The birds were kept in a cage battery under the required microclimate conditions. The effect of feeding experimental additives on the safety of chickens, the intensity of their growth, meat productivity, chemical and amino acid composition of meat (minced meat), hematological parameters was studied. Introduction of protein-vitamin wheat bran meal pure and enzyme preparation Feedbest® P5000 GT into quail mixed fodder increased bird survival by 3.01 %, average daily gain of live weight by 3.09 and 3.44% with almost equal feed expenses per unit production. The fat, calcium and phosphorus content in the meat of poultry fed with wheat bran flour containing phytase increased by 1.17, 1.13 and 1.17 times, respectively. The concentration of calcium and phosphorus in the meat of quail that received flour without enzyme preparation was 1.2 and 1.1 times lower than that of their counterparts that consumed flour with phytase. Biochemical blood parameters of all the experimental chickens remained within the physiological norm.
