EFFECT OF GRAIN MOLASSES ON DIGESTIBILITY OF NUTRIENTS IN FEEDs for DAIRY COWS OF DIFFERENT GENOTYPES
The paper presents results of the study on the effect of grain molasses on nutrient digestibility of forages fed to milk cows of different genotypes. Positive influence of the grain molasses on nutrient digestibility was revealed. Coefficients of protein digestibility in cows of I-experimental group (Austrian Simmentals) were higher by 10.33% than in the control group (purebred Simmentals) and by 8.57% higher than in the II-experimental group (Simmental-Holstein hybrids). Thus, the introduction of molasses has intensified metabolism in cows during milking period and improved the use of mineral nutrients.
