Effect of Bio-Calcium feed supplement on quail growth and development

Abstract

The topical issue of poultry mineral nutrition is discussed. The research targets were 120 dual-purpose Japanese quails. The diets of the quail trial groups included the feed supplement Bio-Calcium in the form of a calcium chelate compound. At the age of 37 days, there was a tendency of body weight superiority in quails of the 2nd trial group (Bio-Calcium 1.0 mL kg) - by 261.60%. By the age of 98 days, the superiority of the body weight of quail of the 2nd trial group remained. When studying blood serum biochemical composition, increasing level of total protein in quails of the trial groups was revealed. At the age of 37 days, the excess was 2.45%, and at 98 days - 2.47%. Creatinine level in the blood serum of quails of the trial groups on the 37th day decreased by 1.88% and 4.09%; on the 98th day - by 4.08% and 4.68%. The AST level in 37-day-old quails under the influence of Bio-Calcium at a dose of 0.5 mL kg decreased compared to the control by 4.54%; at a dose of 1.0 mL kg - by 8.20%. In blood serum of 98-day-old quails, the AST level of the trial groups was lower by 4.22% and 6.85%, respectively. The ALT level in 37-day-old quails was higher than in the control by 3.01% and 18.38%; in 98-day-old quails - higher by 0.32% and 9.74%. Calcium concentration in 37-day-old quails of the 1st trial group was by 122.81% higher than that in the control group; in the 2nd trial group - by 136.84%; in 98-day-old quails - by 120.56% and 147.78% higher. Calcium to phosphorus ratio remained in the optimal range - from 1.5 to 3.0 in quails of all trial groups. Iron content in the blood serum in 37-day-old quails was by 168.33% and 194.82% more than in quails in the control group; in 98-day-old quails - by 115.98% and 136.07%. Magnesium concentration increased in 37- and 98-day-old quails of the 2nd trial group by 27.73% and 49.62% compared to the control.
