Technical methods of raising black goats

Management of pregnant black goats: Black goats should pay attention to these contents in seasonal pregnancy, and farmers must be clear that seasonal changes have obvious influence on the reproductive ability of black goats.

1, from March to May, ewes were kept for a whole winter, with good fatness and normal estrus. It is easy to get pregnant.

From June to August, the weather is hot and the temperature is high. Some ewes often have abnormal phenomena in estrus, such as wigs. The pregnancy rate is not high in this season, and the probability of embryo death is relatively high.

3.9- 10 month, ewes in this season have normal estrus and are easy to get pregnant. It is cold in winter in the northern region, and ewes often have irregular estrus cycles. The wig situation, especially ewes who often drink cold water, will cause reproductive obstacles. At this time, we should pay attention to the living environment of ewes, keep the shed warm and get enough light, and the ewes introduced from other places should pay more attention to the influence of changes on themselves.

Fattening technology of black goat and shelf sheep: choose a tall black goat to fatten, and thoroughly deworm it before entering the fattening circle. There are many drugs that can drive away black goats, such as levamisole and trichlorfon. Afmiddin et al. Generally speaking, deworming should be carried out in black goats on an empty stomach, so as to achieve better results.

When levamisole is used to repel insects, the oral dose is 8 mg per kilogram of body weight. After three days of deworming, sheep should strengthen their stomachs. The commonly used stomach tonic is artificial salt.

Silage feeding method: Silage corn and fresh grass is one of the good ways to fatten mutton sheep. The digestibility of high-quality silage fresh grass is high, and the digestibility of dry matter can reach 70%. Feeding silage corn to mutton sheep can also obtain better daily gain effect.

With the increase of concentrate in diet, the intake of silage corn decreased. Although the daily weight gain increased, the daily concentrate consumption also increased significantly. For mutton sheep that only eat silage corn, it is very beneficial to add a small amount of urea to the diet. When feeding silage corn, it is required to eat less first and then more, and then gain weight after lambs get used to it. At the same time, 2- 10g sodium bisulfate was added to reduce the harm of organic acids.

Ammoniated straw fattening method: ammoniated crop straw can improve the nutritional value of straw, improve the palatability and digestibility of feed, let black goats eat freely, and supplement appropriate concentrate to achieve the purpose of weight gain for mutton sheep. However, because this is a feeding mode with low concentrate and high coarse feed, the fattening time is relatively long, which is not suitable for the large-scale feeding mode with fast turnover and early slaughter.
