Multi-component legume and cereal grasses of intensively type in the first year of use in the diets of highly productive cows

Abstract

The experiments helped to determine that the use of multi-component highly productive legume and cereal pastures allows to carry out in the creation day the second cycle of pasturing and obtain in the summer grazing period a highly succulent and heavy forage. Creating legume and cereal multi-component pastures of local selection provides nutrition value of 1 kg of dry matter of pasture grass on the level of 0,93-0,97 forage units, 10,6-10,95 MJ of metabolizable energy and 121-135 g of digestible protein. Pasturing by highly productive cows with milk yield of 6,0-7,0 thousand kg of milk per lactation of pasture grass of multicomponent mixtures increased the average milk yield of natural milk by 6,8 % compared with milk yields of cows pasturing at cereal grass. Consumption by cows of multi-component mixtures of cereal and legume compared with animals pasturing at cereal pasture has led to an increase in nitrogen balance in the grazing period by 32,4 % and improved digestibility of nutrients (except for crude fat).
