Comparative efficiency of succulent and concentrated rations for Simmental cows
The article shows the results of the research on a comparative study of succulent and concentrated feed. Any type of feeding should include a variety of feeds in the rations, this ensures the usefulness of feeding and helps to increase the milk productivity of cows. The object of research was dairy cattle, which were tested three diets. As a result of the studies conducted on three groups of Simmental cows, it was found that the productive abilities of cows in the experimental groups can be seen by the amount of milk produced per 100 kg of live weight per lactation, milk produced in group 1-st is 726 kg, 2-nd is 768 and 3-rd - 680 kg. The change in diet structure influenced the milk production of cows, so the cows of group II, from the second month of lactation fed high cottages of succulent and green feeds (average 52% nutritional experience for the diet) with 127 g of digestible protein per diet I. units, gave the highest annual milk yield - 4997 kg, having consumed 0,83 feed per 1 kg of milk. When transferring the obtained milk to 4% fat, the results of experimental feeding, in the experimental groups had differences, the animals of group 1 were superior to cows of the second group by 6.5 kg, and the third group by 666.8 kg. More than half of the total nutritional value of the annual rations of cows of group II was represented by succulent and green feeds, whereas in the rations of cows of groups III and I, concentrated feed prevailed. Introduction to the diet of large quantities of juicy and green feed reduced the consumption of concentrates. Cows of group II spent 170 g each, group I 266 g each and group III 304 g per 1 kg of milk. The juicy type of feeding dairy cows of the Simmentals breed was more effective in all the indicators studied.
