Experimental substantiation of the effect of chelated compounds of trace elements on the chemical composition of quail meat

Abstract

The positive effect of chelate compounds of trace elements on the chemical composition of quail meat is justified. The experience used quails of the Japanese breed, egg-meat direction in the amount of 280 heads. Inclusion of chelate compounds of iron and zinc in the diet of quails provides positive correction of physical and chemical indices of meat raw materials. The greatest effect was noted when Bioferron 0,2 ml/kg was introduced into the diet: in 37-day quails, the level of raw protein in meat exceeded the control values by 1,33% (at p≤0,01), the level of raw ash - by 0,41%; in 98-day quails, the level of raw meat protein increased by 1,08%, and relative to the control group - by 1,92% (at p≤0,001), the level of raw meat ash increased by 2,85%, and relative to the control group - by 1,54% (at p≤0,01). In samples of meat raw materials of quail, which received Biocinc, 0,2 ml/kg was noted as the most effective dose: the level of raw protein in meat in 37-day quail exceeded the control by 0,78%, the level of raw ash - by 0,27%; in 98-day quails, the level of raw meat protein increased by 0,85%, and relative to the control group - by 1,14% (at p≤0,01), the level of raw ash increased by 3,45%, and relative to the control group – by 2,00% (at p≤0,01). The highest level of quail in meat raw materials among the elements was in iron, zinc and manganese. The largest amount of digested manganese in the muscles of 37-day quail was noted in a sample of the 5th experimental group (Biocinc 0,2 ml/kg) – 324,69% (p≤0,001) more than the control. In 98-day quails, the highest level of manganese accumulation was also noted in the sample of the 5th experimental group (Biocinc 0,2 mL/kg) – 306,25% (p≤0,001) more than the control one. In 37-day quails, the highest concentration of iron in meat raw materials (60,59±0,66 mg/kg at p≤0,001) was detected when Bioferron was included in the diet at a dose of 0,3 mL/kg, which is 156,63% more than the control. 98-day - 63,32±1,23 mg/kg (p≤0,001), which is 213,93% more than the control. The highest level of zinc was observed in the groups of 37-day quail, the diet of which included Biocinc at doses of 0,2 and 0,3 ml/kg, it was 43,30±0,95 and 44,49±1,41 mg/kg at p≤0,001, which is more than in the control group by 113,41 and 119,27%, respectively.
