摘要
本文介绍了饲用带状带、海草尿素(MTM)和尿素在Tsygay种公羊饲用中的研究结果,以及东弗里西亚公羊在Tsygay种母羊饲用中的效果。这项工作的实验部分是在敖德萨地区的农业地层进行的。在主饲粮中,以适量带状带状蛋白、含氮饲料产品MTM和尿素替代一定量的可消化蛋白质和矿物质。ⅰ组饲粮中带状疱疹25 g,ⅱ组饲粮中MTM 50 g,ⅲ组饲粮中尿素10 g,对照组不含任何杂质。50 g MTM含有25 g带状疱疹和10 g尿素。肉毛产量(活重、绝对活重增重)研究羊毛剪切(物理重、洗涤纤维、羊毛长度)按普遍接受的方法进行。为了确定东弗里西亚公羊对赤盖母羊的使用效果,通过试验研究了杂交母羊的产奶量和新生羔羊的生长强度。以东弗里西亚公羊和赤改母羊杂交羔羊为试验材料,研究了年龄方面的活重生长强度、屠宰品质和肉的氨基酸组成。采用哺乳期、断奶后和整个哺乳期的泌乳量来研究杂交公羊的产奶量。根据普遍接受的方法研究了肉类和乳制品的产量。根据V. P. Kovalenko et al.(2010),采用变分统计方法对数字材料进行处理。由此可见,在饲粮中平衡饲粮中的蛋白质、矿物质和维生素,可使10月龄山羊的活重提高2.9 ~ 7.2%,剪毛体重提高52.8 ~ 55.5%,水洗纤维提高51.1 ~ 53.5%。利用东弗里西亚品种的公羊与齐盖品种的母羊杂交,有助于生产具有良好经济和实用性状的杂交动物。杂交公羊宰前每公斤肉浆产出率比赤改公羊高5.2%,屠宰率提高5.11%。杂交母羊产奶量高,有利于羔羊的生长发育。从出生到1岁的生长期,当地幼羊的活重比纯种Tsygayskii羊高16.9%,牦牛高22.7%,平均日增重比纯种Tsygayskii羊高18.1%和24.6%。
Ways to increase the productivity of sheep of the Tsygay breed in the conditions of southern Ukraine
The article presents the results of the research on feeding zoster, sea grass-urea (MTM) and urea in feeding Tsygay breed rams, as well as the effectiveness of using East Friesian rams on Tsygay breed ewes. The experimental part of the work was carried out in the agricultural formations of the Odesa region.
In the main diet, a certain amount of digestible protein and mineral substances was replaced by an appropriate amount of zoster, nitrogen-containing feed product MTM and urea. The diet of the I experimental group contained 25 g of zoster, the II experimental group – 50 g of MTM, the III experimental group – 10 g of urea, the control group did not contain any impurities. 50 g of MTM contained 25 g of zoster and 10 g of urea. Research on meat and wool productivity (live weight, absolute live weight gain; wool shear in physical weight and washed fiber, wool length) was carried out according to generally accepted methods.
In order to determine the effectiveness of the use of East Friesian rams on Tsigai ewes, an experiment was conducted to study the milk yield of crossbred ewes and the intensity of growth of newborn lambs. In cross-breed lambs obtained from rams of the East Friesian breed and ewes of the Tsigai breed, the intensity of growth of live weight in the age aspect, slaughter qualities and amino acid composition of the meat were studied. The milk yield of crossbred dams was studied by the amount of milk obtained during the suckling period, during the period after the lambs were weaned, and during the entire lactation period. Meat and dairy productivity were studied according to generally accepted methods.
The digital material was processed by the method of variational statistics according to V. P. Kovalenko et al. (2010). It was established that balancing the diet in terms of protein, minerals and vitamins due to feeding zoster, MTM and urea ensures an increase in live weight of 10-month-old goats by 2.9–7.2%, wool shearing in physical weight by 52.8–55.5 %, in washed fiber by 51.1–53.5 %. The use of rams of the East Friesian breed on ewes of the Tsigai breed contributes to the production of cross-breed animals with well-developed economic and useful traits. In cross-breed rams, compared to Tsigai rams, the pulp yield per 1 kg of pre-slaughter mass is 5.2 % higher, and the slaughter yield is 5.11 %.
The high milk yield of cross-bred mothers contributed to better growth and development of lambs. During the period of growth from birth to yearling, the local young outnumbered the purebred Tsygayskii in terms of live weight: lambs by 16.9 %, yaks by 22.7 %, and by average daily growth by 18.1 % and 24.6 %, respectively.
