Description
Technical Field
The invention belongs to the field of animal production in animal husbandry, and particularly relates to a method for feeding mutton sheep in the early stage and feed.
Background
In the last 2 months of gestation, the fetus grows rapidly, 85% of the birth weight of the lambs is completed in the period, the nutrition in the gestation period needs to meet the growth and development of the placenta, the fetus and the mammary gland, the nutrition in the pregnant ewes directly influences the birth weight of the lambs, and the birth weight influences the weaning weight and the slaughtering time. If the nutrition is insufficient in the later stage of pregnancy, the vitality of the newborn lambs is weak, and the survival rate of the lambs is low. The problem to be solved in the mutton sheep production is how to reasonably utilize the physiological characteristics of ewes and lambs to improve the production efficiency by depending on the efficient utilization of the ewes bred by large-scale efficient breeding and the efficient feed return rate of the mutton sheep.
In order to realize the industrialized and intensive production of mutton sheep, the ewe is objectively required to be rapidly bred, and the ewe can produce two or three yields in one year or two or three years on the basis of multiple fetuses, so that the lamb is required to be weaned early. In addition, due to the reasons of one birth and more birth, the poor condition of ewes and the like, the survival, growth, development and health of the lambs are directly influenced. The determination of the weaning age is a key link of the early weaning technology of the lambs, the lambs are weaned too early, the stress response is obvious, the disease resistance is reduced, and the growth and development are hindered; the ewes are poor in fat and feelings after being weaned late, the estrus is delayed, and the utilization rate is reduced. The creep feed can stimulate the rapid development of lamb rumen by using the creep feed in due time, thereby ensuring that the lamb can digest and absorb nutrient substances in the feed well before and after weaning. The weaning day age is determined according to the feed intake of the solid feed for the lambs, so that the lambs can adapt to the solid feed earlier through feeding of creep feed to achieve the purpose of early weaning.
At present, the technology for breeding the mutton sheep in a large scale is still not mature enough, and especially for breeding the lamb, the defects of low survival rate, slow growth, uneven quality and the like still exist. Therefore, it is necessary to invent a method for breeding mutton sheep in the early stage.

After pregnancy, the placenta usually completes 95% of the final weight in the first 90 days of pregnancy, while the fetus only obtains 15% of the final weight, and the ewe's breast begins to develop in 90 days of pregnancy and develops rapidly after 120 days. Therefore, the nutrition of the ewes after 100 days of gestation is a powerful guarantee for solving the birth weight, the larger the birth weight of the lamb, the lower the diarrhea rate, and the higher the survival rate. The method can meet the nutritional requirements of ewes in the lactation period, ensure sufficient milk supply to the lambs, improve the survival rate and weaning weight of the lambs and reduce the diarrhea incidence of the lambs. The milk stage can improve the immunity of ewes, thereby achieving a good source and powerfully ensuring the survival rate of lambs.
The main nutrients of the lambs in the creep stage are from breast milk and supplementary materials. At this stage, the lamb digestive organs have great growth and development plasticity, and the lamb rumen generally has a certain function when growing to 2 weeks, and is mainly the result of food ingestion. The ewes are supplemented with the milk feed in the milk stage, so that the nutrition of the nursing ewes is ensured, the milk yield is improved, and meanwhile, the lambs are fed with the starter food as early as possible through the early stage teaching groove, so that the early stage weaning is realized. The utilization rate of the non-dairy protein source of lambs before 3 weeks is low, so the adopted raw materials are processed raw materials and can be passively digested and absorbed. The section 1 creep feed provided by the invention adopts a raw material which is strong in feeding attraction and good in palatability and is easy to digest and absorb by lambs, and whey protein powder and lactose are added as energy supply substances, so that the creep feed adapts to the digestive tract environment of the lambs just away from milk, the feeding attraction effect on the lambs is improved, and the creep feed is easy.
the method comprises the following steps of using 2 sections of creep feed when the lambs are 35 ~ 75 days old, recommending the feeding amount to be 150 ~ 400g/d (specifically determining the feeding amount according to variety of ewes, roughage quality and local feeding habits), gradually reducing the lactation amount 4 weeks after the ewes are born, and beginning to become a main nutrient source for lamb weight increase along with the gradual improvement of lamb rumen development and function, wherein the lamb weight increase at the stage is rapid, plant raw materials in the 2 sections of creep feed are fermented to generate butyric acid and propionic acid to promote rumen nipple growth and complete rumen development, the weaning of the lambs is generally carried out when the weight reaches about 20kg (2 months old), the standard of weaning is determined by lamb feeding capacity, feeding amount and physical weaning condition instead of being carried out by lamb in month old, the feeding capacity is poor, the feeding amount is low, the physical quality of the lambs is weak, the lamb weaning can be delayed, the lamb 60 days old is recommended to be fed with the anaerobic strain, the lamb growth rate can be improved after the gastrointestinal development condition is fully considered, the lamb digestion rate is improved, the lamb growth rate of the lamb 6 ~ 8 weeks, the lamb is improved, and the piglet growth rate is improved, the piglet growth rate is increased, the growth.
The nursing material of the invention ensures the full nutrition of the weaned lamb and fully excavates the growth potential. Feeding in the nursing stage can promote the better development of rumen, and prepare for later fattening.
The early-stage nutrition three-stage feeding method for the mutton sheep solves the problems of small birth weight, small weaning weight, difficult creep, slow conservation growth speed, low survival rate and the like of the lamb, can improve the immunity of the ewe by regulating and controlling the ewe feed, strongly ensures the survival rate of the lamb, innovatively provides the lamb two-stage creep and adds the lamb conservation stage, promotes the complete rumen development, facilitates the lamb to enter high-precision feed for fattening, shortens the transition period time, reduces the death rate of the feeding period, and shortens the slaughtering time.
