INFLUENCE OF POTASSIUM IODIDE ON GROWTH, DEVELOPMENT AND MEAT QUALITIES OF DUCKS OF THE CROSS "MEDEO"
The studies were carried out on ducks of the Medeo cross in the Urals where Ducklings were kept under brooders for up to 10 days with subsequent transfers to aviaries.The effect of adding potassium iodide (0.05-0.15 mg / kg) to the main diet of ducklings was experimentally studied. It was found that the addition of the preparation improves the growth, development and preservation capacity of growing birds.The live weight in the experimental groups reached 27222834 grams by the age of 49 days, which is 2-88-10.29% higher than in the control group. The preparation improves the preservation capacity of growing birds up to 94.66%, versus 17.74% in the control group.The best indicators of growth, development and meat quality were obtained by adding the preparation to the main diet at a dose of 0.1 mg / kg. Potassium iodide increases the pre-slaughter weight, in comparison with the control group, by 2.87-7.1% and the ratio of meet to bones. Chemical analysis of meat of ducklings at 49 days of age showed that potassium iodide has a positive effect on the mass protein fraction in meat (0.22-0.66%), compared with the control group. The caloric content of 100 g of meat in the 2nd experimental group is higher by 11.36 kcal. The positive effect of the drug on the development of the internal organs of young ducklings was also established.
