The influence of Zinc and Manganese chelates (pantothenates) on some chicken broiler metabolism indicators

Keywords: broiler chickens, pantothenic acid, glycine, Zinc, Manganese, protein metabolism


The article presents the results of the use of the vitamin-amino acid chelates (pantothenates) of Zinc and Manganese in order to study their effect on some indicators of avian metabolism. The studies were started on 14-day Cobb 500 broiler chickens in the poultry farm of the Bila Tserkva National Agrarian University Training and Production Center. For this purpose, 3 groups poultry were formed: two experimental ones (Zinc and Manganese chelates were fed to the main diet with water) and a control group (50 heads each). During the experiment (14, 21, 28 days), weighed chickens followed by blood sampling for biochemical study. In the group where the chelates were drunk at a dose of 0.2 ml/l of water over the next 14 days, there was a tendency to increase the absolute weight gain in broiler chickens to 943.0 ± 25.94 g (770–1073), compared with the control – 883.2 ± 24.64 g (740–1140). The bird, which was given chelates at a dose of 0,1 ml/l of water for 14 days, increased the content of total protein in the serum by 10.3% compared to the beginning of the study, and was 30.9 ± 0.71 g/l (P < 0.001). In the second group (chelate dose of 0.2 ml/l water), this indicator increased by 11.2% and amounted to 30.2 ± 0.82 g/l (P < 0.01). At the end of the experiment (28 days of cultivation), the albumin content in the blood of the birds of the first and second experimental groups was 18.6 ± 0.36 and 18.7 ± 0.37 g/l (P < 0.001 before the first selection). Manganese concentration in broiler chickens of the second experimental group on the 28th day was 3.6 ± 0.28 μmol/l and was higher than the control (2.7 ± 0.25 μmol/l; P < 0.01). At doses of 0,1 ml/l of water (1st experimental group), there was a tendency to increase the amount of this trace element in serum to 3.2 ± 0.16 μmol/l (1.4–4,0). After 14 days of chelating, Zinc content in the serum of chickens of the first experimental group increased by 20% and amounted to 27.9 ± 0.60 μmol/l, in its second – concentration increased by 25.8% (28.3 ± 0.76 μmol/l; P < 0.001) compared to the start of the experiment. Therefore, the use of the vitamin-amino acid chelates of Zinc and Manganese for 14 days at a dose of 0,1 and 0.2 ml/l of water contributed to the increase in weight gain, increase of total protein, Manganese and Zinc in the serum of broiler chickens.
