RYE-ALFALFA SILAGE IN A FULLY MIXED DIET OF MILKING COWS

Nowadays there are problems associated with the decline in corn yield and perennial grasses for silage and haying as the main bulky forage of milking cows caused by recent climate fluctuations observed in years. In order to provide livestock with feed it is recommended to use winter rye silage. It gives high yields of green mass. In order to increase protein nutrition and reduce nutrient losses during silo harvesting and storage, it is proposed to silage 65% to 35% of winter rye with alfalfa using 1.5 g of biological preservative «Bonsilag alfa» per 1 ton.
It was proved that the rye-alfalfa silage had high protein nutrition with a 12.72 g crude protein content per 1 kg of dry matter; it is 4.92 g more than in the corn silage. The degree of cleavage of crude protein of rye-alfalfa silage was higher and amounted to 72.2%, and corn silage has 69.2%.
In terms of energy nutrition, the rye-alfalfa silage was not inferior to maize; the amount of exchange energy per 1 kg of dry matter was 9.41 and 9.37 MJ, respectively.
The «Bonsilag alfa» preservative promoted the normalization of fermentation processes in the maturation of rye-alfalfa silage, the accumulation of lactic acid, whose share was 68.5% of the total weight of acids after 68 weeks, its content (62.3%) in corn silage was lower.
Replacement of corn silage by rye-alfalfa one made from herbs with 70% humidity with the use of the bacterial preservative «Bonsilag alfa» in the fully mixed diet of Ukrainian black-and-white dairy breed cows allowed to increase protein by 228 g (9.7%) for crude protein and 106 g (5.7%) for digestible protein. During the 30 days of the experimental period, the average daily yield of milk fat increased by 1.68 kg or 8.2%, and by 2.13 kg or 9.4%. The fat content of milk increased by 0.04%, and the protein content by 0.01%.
