Efficiency of feed additive use on laying hens

Purpose. Efficiency assessment of the use of feed additive with including in the diet of poultry. Materials and Methods. The conditions of keeping poultry corresponded to the sanitary and hygienic standards adopted in the farm on the basis of which the experiment was conducted, and the requirements of industrial cultivation technology. For the poultry, the planting density, microclimate parameters and lighting mode corresponded to the requirements of the cross. Feeding and watering were carried out in accordance with the rations and norms adopted in the farms. Compound feeds intended for poultry of the experimental groups were prepared separately, in accordance with the draft instructions for the feed additive Acidopul L. Results. When weighed on day 60, the average egg weight of the experimental group 1 exceeded the control analogues by 0.38 g or 0.6%, of the experimental group 2 – by 0.50 g or 0.8%. In terms of egg productivity, laying hens of the experimental group 1 exceeded control analogues by 0.38 eggs/head or 2.9%, of the experimental group 2 – by 0.70 eggs/head or 5.4%. According to the results of a biochemical study of the blood serum of laying hens, the control and experimental groups differed in total protein content: in the experimental group 1, the excess was by 4.15 g / l, or 11.5%, in the experimental group 2 – by 2.50 g / l or 6.0%. Over the entire observation period, the safety of livestock in experimental group 1 was 2.7% higher, in experimental group 2 – 3.6%. According to the intensity of pecking, the poultry of the experimental group 1 was inferior to the control analogues by 0.9%, the experimental group 2 – by 1.8%. Conclusion. The results of the conducted studies indicate that the feed additive Acidopul L in the recommended dosage regimen of 1 liter per ton of compound feed (experimental group 1), 2 liters per ton of compound feed (experimental group 2) is able to have a beneficial effect on poultry products in the form of improved livestock safety.
