Abstract

The highest sensitivity to deficiencies in feeding is shown by highly productive cows Holstein breed that has become widespread both in Russia as a whole and in the Urals region. Against the background of many advantages of the breed, there are problems with reproduction and negative energy balance after calving. An innovative approach in feeding is the enrichment of the ration of animals with the energy and carbohydrate additive “Tanrem”, nutrients of which being natural prebiotics and energy sources, are able to activate metabolic processes. The purpose of the research was to study the effect of the energy and carbohydrate additive “Tanrem” on milk productivity and milk composition of cows of Holstein breed. Scientifi c and economic experiment was carried out in LLC “Agro-Alliance” in the Chishminsky district of the Republic of Bashkortostan. For the experiment cows of Holstein breed for the third lactation were selected in the amount of 40 animals, which were provided with the same conditions of housing. In order to select the optimal dosages of the additive the animals were divided into 4 groups. Cows of the 1st control group received the main ration adopted on the farm. Cows of the experimental groups consumed a ration enriched with the energy and carbohydrate additive “Tanrem” in a daily dose, respectively: group 2 – 250, group 3 – 500 and group 4 – 750 g/head. For 305 days of lactation the superiority of cows of the 2nd, 3rd and 4th experimental groups on the control was as follows: 198,2 kg or 2,39 % (p < 0,05), 458,8 kg or 5,53 % (p < 0,001) and 408,9 kg or 4,93 % (p < 0,001), respectively. The data obtained indicate the expediency of enriching the ration of dairy cows with the energy and carbohydrate additive “Tanrem”. The economic analysis confirmed the established fact and indicated that the most effective rate of application of the tested additive is 500 g/head per day.

能量和碳水化合物添加剂“Tanrem”对荷斯坦奶牛产奶量和乳成分的影响

高产的荷斯坦奶牛品种表现出对饲料不足的最高敏感性，这种奶牛在整个俄罗斯和乌拉尔地区都很普遍。在该品种具有诸多优势的背景下，产犊后存在繁殖和负能量平衡问题。一种创新的饲养方法是用能量和碳水化合物添加剂“Tanrem”来丰富动物的日粮，其中的营养成分是天然的益生元和能量来源，能够激活代谢过程。本试验旨在研究能量和碳水化合物添加剂“Tanrem”对荷斯坦奶牛产奶量和乳成分的影响。科学和经济实验是在巴什科尔托斯坦共和国奇什明斯基区的有限责任公司“农业联盟”进行的。试验选用荷斯坦品种第三期泌乳奶牛40头，饲养条件相同。为了选择最佳的添加剂剂量，将动物分为4组。第一对照组饲喂农场主日粮。试验组奶牛日粮中分别添加能量和碳水化合物添加剂“Tanrem”，分别为:2 ~ 250 g/头、3 ~ 500 g/头和4 ~ 750 g/头。泌乳期305 d，第2、3、4试验组奶牛产奶量较对照组的优势分别为:198,2 kg和2.39% (p <0,05)， 458,8公斤或5,53 % (p <0,001)和408,9公斤或4.93% (p <分别为0001)。结果表明，在奶牛日粮中添加能量和碳水化合物添加剂“坦勒姆”是有益的。经济分析证实了既定的事实，并表明试验添加剂的最有效的应用率为每天500克/头。
