In the Middle Volga region, alfalfa is the most widely used bean fodder. In recent years, one more bean crop is used – Fodder galega. The main disadvantage of almost all legumes is low sugar content and poor haylage making abilities. To eliminate this drawback, the biological product “Silostan” was developed. It is used as a preservative. The aim of the work is to study the effect of alfalfa and Fodder galega haylage made using the bio-preservative “Silostan” on milk production and quality of milk of black and white Samara cows. The use of Silostan increased the dry matter content by 5.2 and 4.5, ECE – by 12.8 and 17.5%, and digestible protein – by 27.1 and 15, 5%. The digestibility of dry matter increased – by 3.85 and 4.38%, crude protein – by 5.68 and 5.42%, crude fat– by 4.26 and 5.26%, crude fiber by 3.86 and 4.07%. The use of haylage with bio-preservatives increased the yield of cows for 305 days of lactation by 14.6 and 16.5%. The MFF increased by 0.05 and 0.06%, MFP – by 0.07 and 0.09%, respectively. The technological properties of milk improved, the milk consumption per 1 kg of ripened cheese decreased by 4.9 and 11.2%.
