PRODUCTIVE QUALITIES OF BLACK-SPOTTED COWS FED RATIONS SUPPLEMENTED WITH ENSILAGED ALFALFA HAYLAGE
The article presents data on the milk yields of cows for the period of 100 and 120 days of lactation, consuming alfalfa haylage, preserved with different dosages of the Biotroph preparation. The experiment was carried out with full-aged Black-Spotted cows, under the conditions of the Republic of Bashkortostan. The Biotroph preparation was used in the doses of 2, 4 and 6 liters per 1 ton of alfalfa mass. It has been established that feeding cows with the use of haylage, treated with the preservative Biotroph preparation of different concentrations, contributed to certain improvement of the animals’ productive qualities. The intergroup analysis of the values of the mass fraction of fat showed that, starting from the second month and until the end of the experiment, there were observed leading positions of cows, consuming preserved haylage. A similar pattern was manifested in the protein content. The highest level of productive qualities was demonstrated by cows consuming haylage treated with the Biotroph preservative, its working solution concentration being 4 liters per 1 ton of preserved green mass.
