THE EFFECT OF FEED QUALITY ON THE PRODUCTIVITY OF THE DAIRY HERD

Abstract

The production of high-quality milk depends primarily on the feed being fed, which must be hygienically impeccable, technologically properly preserved and at the same time meet the physiological requirements of animals. To determine the suitability of herbal crops for silage, it is necessary to know the chemical, physical and biological properties of these plants. A large amount of crude protein in herbage always indicates a high buffering capacity. Therefore, grasses and especially legumes, as a rule, are more difficult to ferment into silage than corn. With a higher concentration of sugar in the silage mass (over 3 %), the yield of lactic acid increases to 50–70 %, while its actual amount is 3–4 times higher than the required level, which is the reason for obtaining «peroxidized» silage, therefore, only those plants with a sugar-buffer ratio of 1,7–4,0 and a sugar concentration in the natural mass of the order of 1,5–3,0 are considered to be easily siloed crops.
