Problems solved by technology

At present, the production of mutton sheep in large-scale sheep farms mainly uses hormone methods to prevent and treat reproductive disorders in ewes. The hormones used mainly include follicle-stimulating hormone, luteinizing hormone, serum gonadotropin of pregnant horses, human chorionic gonadotropin, progesterone and prostaglandins. And its analogues, etc., the effect of hormone therapy is better, but the application cost of this method is high, the operation is troublesome, time-consuming and labor-intensive, and it is not easy to popularize and apply in production

Abstract

The invention relates to a compound premix for improving reproductive performance of mutton sheep and a preparation method thereof. Organic carriers are added to beta-carotene, vitamin E, vitamin A, vitamin D, calcium, phosphorus, iron, copper and trace elements such as manganese, zinc, selenium, potassium and cobalt and evenly mixed, and the mutton sheep compound premix which is balanced in nutrition is made. The compound premix is mainly used for young ewes, ewes mating for the first time and not reproducing, multiparity ewes and ewes out of heat after birth, and the adding proportion is 4-6% of concentrate supplements. Results of feeding trial show that the compound premix enables the average first matching age of the young ewes to be 11.4d earlier than that in a control group; when the compound premix is used for feeding the multiparity ewes, the average interval between parturition and mating is shortened by 4.2d in comparison with the control group, and the average lambing percentage is improved by 10% in comparison with the control group. The compound premix is simple in producing processing process, wide in raw material sources, economic and efficient, can be directly added to daily ration of the ewes in the feeding process, is convenient to operate, and facilitates large-area popularization and application in massive sheep yards and scattered raising households.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed for herbivorous mutton sheep and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, herbivores mainly cattle and sheep have developed rapidly. As a grain-saving animal husbandry, the mutton sheep industry has developed in a large-scale and standardized direction. Problems such as the decline in the number of lambs are largely due to reproductive problems. The reproductive problem is mainly manifested in the fact that the ewes do not estrus after giving birth, so that most ewes cannot be mated in time after giving birth, and the time between postpartum and mating conception is prolonged, that is to say, the ewes are empty or infertile. This phenomenon not only increases Feeding management and breeding costs of ewes, and reduce the number of lambs in sheep farms, directly affect the economic bene...
