According to local conditions, good varieties are selected, and the improved and improved sheep breeds are large in size, fast in growth, high in reproduction rate, strong in adaptability, good in meat quality and high in efficiency. At present, there are mainly Boer goats, Sharon goats and Huanghuai goats. At present, most of the goats raised by farmers are mainly local varieties, with small individuals, slow growth and low rate of slaughter, so the benefits are not high. In order to reverse this situation, the Boer goats and the Sharon goats should be introduced for hybridization improvement. For example, Boer goats are crossed with native goats and weigh nearly 10 kilograms at 6 months of age compared to local sheep, which can significantly improve efficiency.
Reforming traditional feeding habits
1. Remixing grazing into a single group of grazing. For the lambs, according to the physiological characteristics and living characteristics, the single group is grazing nearby, and the extensive management is carefully managed to strengthen the early cultivation, so that the lambs can eat milk well, wean early, graze early, feed early, and accelerate their growth and development.
2. Change the extensive feeding management to fine feeding management. First of all, we must grasp the season grazing, the autumn weather is cool, and the nutritional value of the herbaceous seed is high. It is the golden season of grazing. At this time, we should graze as much as possible to let the sheep eat more grass. The winter climate is cold, try to graze as little as possible, and let the sheep exercise properly. You can, add high-quality hay and concentrate; the spring weather is cold and changeable, let the sheep run less and eat more; the summer weather is hot, the mosquitoes and flies are more, and the two heads are grazing as much as possible in the morning and evening. Secondly, make full use of the green concentrate produced by the farmer to supplement the feed.
Regular deworming and medicated bath sheep are highly susceptible to infection of parasites in and out of the body during the feeding process, resulting in slow growth of sheep, low resistance, and serious death. Therefore, sheep farmers should be carried out annually according to the prevalence of parasites. Deworming and medicated bath. Usually the first deworming is carried out in the spring, and the nematodes such as levamisole or worms are used, and the chlorpheniramine is used once every 5 to 7 days, and once again in the autumn. The medicated bath is carried out once a year in spring and autumn. The weather is warm and the temperature is 35 °C. It takes 0.5 to 2% of trichlorfon and sulfur for 1 to 2 minutes.
