The article discusses the efficiency of keeping laying hens in organic farming.
The use of prophylactic drugs based on probiotic microorganisms Lactobacillus
plantarum and postbiotic "Bacteriosan" - the development of employees of the Department
of animal hygiene and sanitaon. prof. A. K. Skorokhodko.
The research was conducted in a certified organic farm. In one of the premises of the
organic farm, experienced chickens were kept, they were fed organic food, and a probiotic
drug based on the Lactobacillus plantarum strain was added to the water in a dosage of
1 g / l daily, for 7 days, with a week break throughout life. In another room, experienced
chickens were also kept, they were fed organic food, and a solution of postbiotic "Bacteriosan"
was added to the water (100 ml of 40 % lacc acid + 0.05 g of bacteriocin nisin +895
ml of H2O), at a dose of 1 ml / l daily. The third room contained chickens of the control
group (K), which received organic food without additives, no preventive drugs were used.
The following parameters were studied in laying hens: live weight, egg laying intensity,
weight of the egg and its components (protein and yolk), shell thickness.
Analysis and interpretation of the experimental data obtained prove the positive
effect of both these drugs, compared with the control. There was an increase in the live
weight of laying hens and the intensity of egg laying, the latier in the first experimental
group (probiotic) was 75.09 %, and in the second (postbiotic) - 76.50 %, against 70.30 %
- in the control group. Similar changes were found in relation to the weight of eggs and
the weight of their components (yolk and protein), as well as the thickness and weight
of the shell compared to the control group of birds. Probiotic Lactobaillus plantarum
and postbiotic "Bacteriosan" are recommended for use by laying hens for their content
and production in organic poultry farming.
