(agricultural Wealth net) what is the efficient feeding method of Boer crossbred mutton sheep? Boer crossbred sheep produced with Boer goat as male parent have the characteristics of fast growth rate, high slaughtering rate and delicate meat quality. Since hybrid sheep grow and develop faster than local sheep, especially in the six to nine months after birth, their body weight can be doubled as that of local sheep, so they have a relatively high demand for nutrition and cannot be treated in the same way as local sheep. Appropriate supplementary feeding should be carried out on the basis of local sheep diets. The amount of supplementary feeding generally depends on the demand for nutrition for weight gain and the resources of green feed in different seasons. In general, crossbred sheep born in spring may not be fed properly except for fattening before and after weaning and before listing in places with more forage resources. However, hybrid sheep born in autumn and winter generally need supplementary feeding, otherwise the early growth and development will be affected and the heterosis will not be obvious. Supplementary feeding is generally supplemented with mixed concentrate at 0.5% or 1% of the body weight of hybrid sheep. Feeding and management measures should be put in place for Boer crossbred sheep as a high-quality mutton sheep breed, and the feeding and management measures of "improved breed + good method" must be used. Only by adopting scientific feeding and management methods can obvious feeding benefits be achieved. The following points should be paid attention to in the feeding and management of Boer hybrid mutton sheep: the prevention and control of epidemic disease is particularly important for raising Boer hybrid mutton sheep. The epidemic prevention method of "one sheep with two needles and three combined with four vaccines" has a better effect. The sheep after castration in time is gentle, easy to manage, easy to fattening, and can reduce the taste and improve the quality of mutton. Lambs are usually castrated about two months after birth, and late castration affects growth and weight gain. Regular deworming parasites can seriously affect the growth rate of hybrid mutton sheep, so the deworming work of hybrid mutton sheep is very important. In general, trematodes and nematodes are repelled in spring and autumn, tapeworms every two months, and external parasites in spring, autumn and winter. In order to reduce the workload of deworming, avermectins can be used to remove parasites both in vivo and in vitro. The short-term fattening technique can effectively improve the growth rate and mutton quality of Boer hybrid mutton sheep and increase the economic benefit. The effect of short-term fattening technology of hybrid sheep before going on the market is particularly prominent. Generally, a month before going out of the fence, under normal grazing conditions, hybrid sheep about 6 months old are supplemented with 150 grams of corn, 100 grams of wheat bran, 50 grams of soybean meal and 3 grams of bone meal every day. After about a month of fattening, they can gain 6 kg to 8 kg. Raising and popularizing commodity hybrid lambs in the same year is of great significance to reduce the need for forage in winter and spring, avoid "death in winter and thin spring" and improve the commodity rate. The crossbreeding utilization of Boer sheep provides more favorable conditions for lambs to be listed in that year, because the early growth rate of hybrid sheep is particularly fast, and the body weight can reach 25 kg to 30 kg at the age of 6 months. Even hybrid sheep born in autumn can grow to about 20 kilograms at the age of 4 months as long as they strengthen nutrition and reasonable supplementary feeding, when it is the cold winter month and around the Spring Festival, it is the peak consumption season of mutton sheep, and the prices of mutton sheep and mutton are high. In addition, a reasonable arrangement of mating time is also an effective measure to ensure that the lambs are listed on the market that year and achieve high returns. Proper use of additives Boer crossbred mutton sheep has higher nutritional requirements, the normal diet can not provide comprehensive feed nutrition, so it is necessary to use some additives properly. There are many kinds of additives, and their main functions are to supplement nutrients, promote growth, prevent diseases, maintain good health and so on. The commonly used additives of mutton sheep are mineral additives, rare earth feed additives and deworming health additives. Proper use of additives can not only promote the growth of muscle and fur, but also promote the development of bones. At present, what is widely used in the market is to make licking bricks, which only need to be hung in the sheep shed for sheep to lick freely. However, the use of hormone additives prohibited by the state is strictly prohibited.
