- Abstract
Research was conducted in the aspect of preservation the gene pool of aboriginal Lebedyn cattle in the Sumy region of Ukraine, which belongs to the brown breeds of the world. Cows of the Lebedyn breed are characterized by good indicators of milk productivity. Milk yield for 305 days of the first, third and highest lactation, respectively, amounted to 4,446, 5,281 and 5,292 kg of milk with a fat content of 3.82-3.87% and protein of 3.33-3.35%. The presence of lactose in the milk of Lebedyn cows ranged from 4.68-4.73%, and dry matter - 12.61-12.72%. A negative correlation was established between the amount of milk and the content of fat (r=-0.014...-0.367) and protein (r=-0.051...-0.212) depending on the estimated lactation. A fairly close and reliable positive correlation between protein and fat content was established (r=0.326...0.651), which allows effective indirect selection between these traits.
