Supplementary feeding feed for tibetan sheep ewe in pregnancy and preparation method and supplementary feeding method thereof

Abstract

The invention is feed suitable for supplementary feeding of tibetan sheep ewe in pregnancy in alpine pastoral areas of tibetan plateau and a preparation method thereof, and is characterized in that corn, highland barley, table salt, a composite premix, and a rape cake are scientifically blended according to the nutritional requirement characteristics of tibetan sheep in pregnancy, and are processed into particle feed which is suitable for feeding and transportation and is used for correct supplementary feeding of tibetan sheep ewe in pregnancy. According to the invention, a supplementary feeding formula which is determined to be suitable for local agricultural and sideline product resource conditions and the nutritional requirement characteristics of tibetan sheep is adopted; by supplementary feeding of ewe in late pregnancy, the nutritional requirements of a fetus for rapid growth are met, and thus the survival rate of lambs is effectively increased. Meanwhile, an important local agricultural and sideline product of a rape cake is made full use of to reduce production cost, and particles are prepared which can overcome practical difficulties of far transportation distances and dispersed feeding sites, and are suitable for popularization and application in alpine pastoral areas of tibetan plateau.

Description

technical field [0001] The invention belongs to the technology of producing livestock feed with plant materials, more specifically, it is a kind of feedstuff with agricultural and sideline products in the alpine pastoral area of ​​the Qinghai-Tibet Plateau as the main raw material, and the formula is designed according to the nutritional requirements of Tibetan sheep and ewes during pregnancy, and processed into formula pellet feed Techniques for supplementary feeding. Background technique [0002] Tibetan sheep form a self-contained system in the alpine grassland animal husbandry production system on the Qinghai-Tibet Plateau, accounting for about 65%-70% of the animal breed structure, and are the main body of the animal husbandry economy. The harsh alpine living environment, coupled with the seasonal imbalance of natural pasture nutrition, causes the nutritional imbalance of Tibetan sheep under natural grazing conditions. state. Carcass nutrition goes through a vicious c...

Problems solved by technology

[0003] In particular, due to the high altitude of the Qinghai-Tibet Plateau, harsh climate, and long cold season, the nutritional level of pastures has been low for nearly 7-8 months, which seriously affects the healthy development of pregnant ewes and fetuses. The birth rate of lambs is low, and the weaning survival rate of lambs is low. The incidence of nutritional diseases is high, and the growth rate is relatively slow, which leads to the failure of the lambs to be slaughtered in the same year, and the extension of the feeding time increases the pressure on the grassland (He Changfang, Su Liping, Han Zengxiang, 2008)
