Embodiment 1

[0022] Brief introduction to the basic situation of the farm: about 200 Nanjiang yellow sheep are raised annually, 7 rams are used for breeding, and 4 long-term laborers are employed. They are raised in semi-captive breeding. Under normal circumstances, they are grazing for an average of 5-7 hours a day and plant pasture land. 0.3hm 2 Plant ryegrass in winter, sweet sorghum in summer, and sweet sorghum silage from July to September. The ewes are mainly fed with corn and bran, and they are fed directly. The pellet feed formula for lambs is 50% corn and 15% wheat bran. %, 30% bean cake, 1% salt, 2% fishmeal, 2% trace element additives, processed into a pellet feed with a diameter of 4.5mm and a length of 10mm. %, phosphorus 0.26%, the dry matter, crude protein, calcium, and phosphorus content of each feed raw material are based on the measured values, and the lambs are supplemented with commercial milk when the normal milk is insufficient.

[0023] The specific operation is as...

Abstract

The invention belongs to the technical field of animal husbandry, and particularly relates to a method for enhancing birth efficiency of lambs during lactation through standardized feeding management of the ewe and the lambs. The method comprises the following steps: promoting the ewes enter the oestrus period at the same time, and intensively mating; manually separating the ewes and the lambs after the ewes give birth to lambs, weaning the ewes, promoting the ewes enter the oestrus period again, and finishing the lactation of the ewes; and manually feeding the lambs with colostrum, feeding the lambs with common milk after the lambs defecate, then gradually exchanging the common milk with fine feed or granulated feed to feed the lambs, and finally feeding the lambs with weeds after 3 to 4months to make the lambs enter the fattening period. Aiming at the problem of low birth rate of sheep cultivating industry, the invention provides an integral lactation lamb birth technology integrating the ewe matting, the lamb birth, the colostrum (common milk) distribution, the ewe weaning and the lamb feeding planning. The method provided by the invention enhances the birth capability of the lamb, shortens the breeding cycle of the ewes, and scientifically solves the actual problems of the large-scale sheep birth at the same time, thereby having a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and more specifically relates to a method for improving the production efficiency of lactating lambs through standardized feeding management of ewes and lambs. Background technique [0002] With the development of economy and society, the improvement of people's living standards, and the change of dietary structure, the proportion of mutton in the meat market consumption is getting heavier and heavier. The demand for high-quality mutton continues to show a growing momentum, prompting the mutton sheep industry to gradually scale. , The direction of intensive development. Compared with other major meat-using livestock and poultry, sheep have a longer reproductive cycle and are in seasonal oestrus. The number of lambs is mainly single or double lambs. The annual meat supply of breeding ewes is low, which restricts large-scale sheep raising one of the important factors. Although the promot...
