Physiological parameters of blood and intensity of growth processes of chickens under the influence of a complex of amino acids

Abstract

The purpose of the study is to examine the morphofunctional indicators of blood and the dynamics of weight-growth indices of chickens when using the Ergamin amino acid complex. Two groups of day-old roosters of the Highsex-Brown cross were formed: a control group and an experimental group. The birds in the control group received a balanced main diet. For the chickens in the experimental group, the Ergamin amino acid complex was added to the main diet at a dose of 10 g/l for the first ten days of life. Blood samples were collected on the first, third, fifth, seventh, and ninth days after the feed additive was discontinued. The chicks were weighed and their body length was measured every two days until they reached 25 days of age. The results were used to calculate weight and growth indices, including absolute body weight gain, relative body weight gain, specific body weight growth rate, and body mass index. The analysis of hematological blood parameters indicates that the feed additive does not have a negative effect on the physiological state of the chicks when administered at a dose of 10 g/L during the first ten days of life. There is no inhibitory effect on the respiratory function of the blood, and there is a slight increase in the levels of hemoglobin and red blood cells in the blood. The studied white blood cell parameters indicate that the amino acid complex does not have a negative impact on the immune system of the chicks. The use of the feed additive does not lead to intoxication or inflammation in the experimental group of animals. By the end of the experiment, the weight of the chickens that received Ergamin was higher than the control values, on average, by 2.8%.
