Efficiency of different standards use in dairy cows feeding
Abstract
The results of research on the efficiency of the dairy cows feeding standardsin the U.S., NRC (2001), British, FIM (2004), Russian (2003) and the new Ukrainian (2009) in single farm conditions. Estimating yields of milkone should note that during the 300 days of the study group I cows gave 5242.8 kg of milk, group II - by 7.4 % more, group III - by 11.4 % and IV - by 14.8 %. It is appropriate to continue the thorough study of the efficiency of different standards using different types of feeding including pastures.
