Carnitine-containing complex for the prevention of acidosis in birds

Meat poultry farming needs high-quality feed and biologically active substances necessary to meet physiological needs of the poultry. For the purposes of the experiment, the experimental group of layers of the Cobb-500 cross was fed with a carnitine-containing feed additive for 5 days. The content of total protein, calcium, phosphorus, reserve alkalinity and carotene in blood serum was studied on biochemical analyzers with subsequent mathematical data processing. After the experiment, the hens of the control group showed an increase in total protein by 42.01%, carotene - by 127.96%, a decrease in reserve alkalinity - by 10.11%, calcium - by 26.90%, and phosphorus - by 20.00%. The calcium-phosphorus ratio was 1.76. In the experimental group of hens the following results were observed: an increase in total protein - by 7.68%, carotene - by 9.80%, reserve alkalinity - by 48.20%, calcium - by 16.67%, phosphorus - by 23.57%, calcium-phosphorus ratio of 2.02. In the hens of the experimental group, on the background of the feed additive, the level of total protein is less than in the control group by 26.91%, carotene - by 56.65%; more content of total calcium - by 65.09%, inorganic phosphorus - by 44.17%, reserve alkalinity - by 59.22%. In the experimental group of hens, the content of carotenoids in the yolk of eggs is 7.30% higher than in the control group. Therefore, the use of a feed carnitine-containing additive with a highly concentrated type of feeding helps to increase the content of total calcium and inorganic phosphorus, to maintain the calcium-phosphorus ratio at an optimal physiological level; increases the level of reserve alkalinity, preventing the development of acidosis; reduces the content of total protein, prevents the development of hepatosis (protein-granular and fatty degeneration of the liver); promotes the conversion of carotenoids into the yolk of a chicken egg, preventing the accumulation of pigment in the subcutaneous fat layer.
