Changes in the physiological status of agricultural animals and poultry under the influence of biologically active additives

The article presents and describes the results of using biologically active additives in the diets of farm animals and poultry. During the experiments, a positive effect of introducing a protein vitamin-mineral concentrate (PVMC) and a premix based on the Sarepta feed concentrate obtained from vegetable raw materials into the diets of calves, young chickens, and broiler chickens was discovered. The use of the developed premix allowed increasing the content of erythrocytes in the blood of calves by 0.35 %, of hemoglobin-by 3.28 %, of protein-by 1.77 %, of calcium-by 2.22 %, and of phosphorus-by 1.68 %. It should be noted that the average daily live weight gain of the unweaned calves increased by 3.36 %; the live weight at the end of the experiment with the unweaned calves in the experimental group was higher by 2.24 % than that in the reference group. During the second experiment with young laying hens, positive results have also been obtained. With the introduction of the premix based on the feed concentrate obtained from the Sarepta vegetable raw material, the content of erythrocytes in the blood of the young hens increased by 1.3 %, of total protein-by 6.34 %, of glucose-by 4.93 %, and of calcium and phosphorus-by 12.5 %. It should be noted that the average daily live weight gain of the young chickens in the experimental group was higher than that in the reference group by 6.93 %, and the total live weight gain-by 7.0 %. During the third experiment with broiler chickens, the following positive results have been obtained. The use of the PVMC based on the Sarepta concentrate developed by the authors resulted in the increase in erythrocytes in the blood of broiler chickens by 8.67 %, total protein-by 1.75 %, calcium-by 5.82 %, and phosphorus-by 7.74 %. With that, the average daily live weight gain of the broiler chickens in the experimental group was higher than that in the reference group by 10.27 %, and the total live weight gain was higher by 10.37 %. Based on the performed research, it is possible to recommend introducing the premix and the PVMC based on the Sarepta concentrate as filler into the diets of farm animals and poultry with the aim of intensifying the metabolic processes in their organism, as confirmed by the provided data about productivity and proven in hematological studies.
