The influence of phytobiotics on the productivity and reproductive system of repair young laying hens
The aim of the work was to study the effect of a phytobiotic feed additive on the live weight, growth and slaughter performance of repair young laying hens. For the experiment, 4 analogue groups of chickens of the “Dominant” egg breed, 150 heads each, were selected. Experimental groups of repair you...

| description | The aim of the work was to study the effect of a phytobiotic feed additive on the live weight, growth and slaughter performance of repair young laying hens. For the experiment, 4 analogue groups of chickens of the “Dominant” egg breed, 150 heads each, were selected. Experimental groups of repair young animals consumed the investigated phytobiotic supplement in different doses in addition to the main diet. The experiment for repair young laying hens lasted 105 days. It was established that the use of a phytobiotic additive in the feeding of repair young laying hens increases the live weight of birds in the 2nd group by 9.4 % (Р < 0.05), the 3rd by 9.9 % (Р < 0.05) and the 4th by 10.5 % (Р < 0.05), against the control group. With the additional consumption of the feed additive, the absolute increase in live weight of chickens in the 2nd group increases by 10.5 % (Р < 0.05), the 3rd by 11.1 % (Р < 0.05) and the 4th by 11.9 % (Р < 0.05), compared to the control value. It was found that the use of a phytobiotic additive in poultry feed increases the length of the keel in the 2nd group by 4.0 % (Р < 0.05), the 3rd by 7.1 % (Р < 0.05), compared to control peers. In addition, under the action of the phytobiotic, the pelvic width in young laying hens increases in the 2nd group by 19.5 % (Р < 0.05), the 3rd by 24.4 % (Р < 0.01) and the 4th and by 21.9 % (Р < 0.01), relative to the control group. With the additional use of the feed additive in the 3rd group of birds, the breast depth increases by 12.6 % (Р < 0.01), compared to the control group. It was established that the consumption of a phytobiotic supplement in repair young laying hens increases the weight of the carcass of the carcass in the 3rd group by 6.8 % (Р < 0.05) and in the 4th by 5.9 % (Р < 0.01), the weight of the heart in the 2nd group by 20.7 % (Р < 0.05) and the weight of the lungs in the 4th by 42.4 % (Р < 0.001), relative to the control value. Under the action of the phytobiotic, in the 4th group of birds, the weight of the left ovary increases by 4.4 % (Р < 0.05), and the weight of the protein part of the oviduct in the 3rd group increases by 85.7 % (Р < 0.05) and 4th by 78.5 % (Р < 0.05), compared to the reference indicator. |
