Technical Field

The invention belongs to the technical field of animal husbandry feeding, and particularly relates to a feeding method for improving the survival rate of southern lambs.

Background

According to the national strategic requirements, the livestock industry in China is in urgent need of transformation and upgrading, wherein the structure occupation ratio of the mutton sheep industry is increased year by year, and the sheep raising scale and the standardization degree are gradually improved. However, the whole sheep raising industry in China is still in the primary stage of intensive breeding at present, and the problems of low severe specialization degree, extremely low informatization degree, backward breeding technology, high breeding cost and the like are faced, wherein the key link for limiting the healthy and rapid development of the sheep raising industry is that the survival rate of lambs is low, and the southern goats have invisibly increased survival pressure of the lambs due to severe climatic environments such as high temperature and high humidity in summer, low cold and humidity in winter, large temperature change in spring and the like; in the traditional lamb feeding management, a pregnant ewe is delivered in a centralized feeding hurdle, after the ewe is delivered, the death phenomenon of part of newborn lambs is frequent due to treading, squeezing or frightening of the delivered ewe by other ewes, so that the lambs have to go through the first ghost gate in the traditional feeding management mode, and the survival rate of the lambs in a plurality of farms is lower than 30%. Secondly, due to climate reasons such as high temperature and high humidity in summer, low cold and humidity in winter and the like in south, and the sanitary environment problems of farms, insufficient secretion of colostrum of ewes caused by problems such as postpartum weakness of ewes, intractable mastitis, delayed secretion of physiological colostrum and the like in the breeding process, the newborn lamb colostrum is insufficient in feed intake and delayed in intake time, so that a good immune epidemic prevention system cannot be established for the newborn lamb body, the later-stage lamb survival rate and the growth performance are influenced, and the healthy development of the goat industry is greatly limited.

When the lamb is born, the intestinal function is immature, the immune system is incomplete, and the nutrient substance requirement of the lamb completely depends on the nutrient components and immune factors of breast milk. The breast milk is rich in key nutrients and immune globulin required by newborn lambs, and helps the newborn to establish a complete immune system and gastrointestinal functions. The lamb cultivation method aims to avoid the problems that the lamb growth and development are limited, the gastrointestinal tract function and development are insufficient, the immunity is low, the disease symptoms are multiple and the like due to insufficient or lack of breast milk secretion caused by the physique of the ewe. Based on the problem that the survival rate of the lambs is low due to the problems, the search for a full-value nutrient for breast milk substitutes becomes the key for improving the survival rate of the lambs.

Besides the nutrition requirement and the sufficient intake of immune protein, another important factor influencing the survival rate of the lambs is the feeding management of the lambs, at present, the goat breeding industry is mostly in a rough stocking and half-barn breeding mode, and many factors such as temperature, humidity, ventilation, illumination, waste cleaning frequency, feeding management mode, environmental noise index and the like in the environment of a breeding farm, so that the influence on the living environment of the lambs, particularly the influence on the lambs by waste gas is large, serious lambs diseases such as eye dermatitis, aphtha, dysentery, diarrhea and the like are easily caused, the stress resistance of the lambs is reduced, but the mortality rate of the lambs in the lactation period and the weaning period is high, and the large-scale and intensive development of the lambs in the whole breeding industry is influenced.

The lamb early feeding and early weaning are realized by inducing the early goats to feed refined feed and coarse feed, so that a solid foundation is laid for normal feeding. The ewe can enter the next breeding cycle quickly, and meanwhile, the early feeding and weaning can contribute to gastrointestinal development, the improvement of the immunity of the organism and the capability of resisting environmental change, and the method is an important technology for improving the growth development and the growth performance of the lamb. The early weaning of the lambs can promote the ewes to estrus in advance, shorten the breeding cycle and improve the survival rate of the lambs and weak lambs, the early weaning of the lambs can enable the lambs to eat the vegetable feed in advance, and the supplementary feeding of the milk replacer can enable the lambs to obtain more sufficient nutrition, thereby being beneficial to the development of the digestive system and the internal organs of the lambs. Three factors of breast milk breaking time, formula and starter nutrition level and formula breaking time become important components of early weaning technology. Early weaning techniques were concluded under experimental conditions and no determination of weaning time was made. The optimal weaning time and the optimal milk replacer time have important influences on the growth of the lambs, the development of digestive tracts, the feeding cost and the like. The time to break breast milk and formula and starter are more studied, but the optimal time to break milk is not clear. Formula can promote the development of lamb digestive tract, especially rumen, so the formula breaking time is different from the weaning in traditional breeding. At present, the feeding cost of the formula is considered to be higher in production, the formula breaking time is earlier, and the growth and development of lambs are seriously influenced. The early weaning of the lambs is beneficial to the recovery of the body condition of the postpartum ewes as soon as possible, and the condition reaches 1 year 2 birth or 2 years 3 birth. Is beneficial to improving the survival rate of one fetus and multiple lambs and improving the breeding benefit. The early weaned lambs can eat the solid feed earlier, so that the development of a digestive system is promoted, and the early weaned lambs are favorable for timely marketing and fattening and large-scale production and operation. Factors influencing the success of early weaning are many, and the factors which play a decisive role are the age of the early weaning day, the substitute of goat milk, the nursing of lambs, the physiological characteristics of the lambs and the like. The early weaning day age is a key link for the success of the early weaning technology of the lambs and is a problem which must be faced by large-scale sheep raising.

According to the traditional lamb feeding management mode, the pregnancy of a pregnant ewe is not tracked, the ewe is delivered in a centralized feeding hurdle, after the ewe is delivered, the death phenomenon of part of newborn lambs is frequent due to the fact that the ewes are stepped on, extruded or frightened by the ewe during delivery and the like, and therefore the lambs need to be subjected to the first ghost gate closing in the traditional feeding management mode. Secondly, due to climatic reasons such as high temperature and high humidity in summer, low cold and humidity in winter and the like in south and the sanitary environment problems of a breeding farm, the mastitis of the ewes is high, the ewes are fed coarsely to ensure that the nutrition intake of the ewes is insufficient, the lactation of the ewes in the lactation period is insufficient, the breeding strange image with high rate of double lambs or triple lambs and extremely low survival rate in the goat industry in south is caused, the average survival rate of the lambs in the goat breeding industry in south at present is less than 30%, the problems of diarrhea, keratoconjunctivitis and the like are prominent, the growth performance of the lambs is greatly influenced by the breast milk of the ewes, the growth performance such as average daily gain, weaning weight and the like is low, and the healthy development of the goat.
