What kind of sheep is suitable for breeding in the north?

Small-tailed Han sheep or Boer goat, etc. The cold weather in the north is suitable for raising sheep with strong cold resistance and adaptability. Small-tailed Han sheep is a unique high-quality mutton sheep breed in the Yellow River Basin. They have the characteristics of fast growth and cold tolerance, and are suitable for breeding in cold weather. Boer goat is known as "the king of goats in the world". They have the characteristics of large size, fast growth, tender meat, rough feeding resistance, strong adaptability and strong disease resistance, so they are also suitable for breeding in the north. ?

1. Which breed of sheep is good in the Northern Circle?

It is understood that the northern circle is more suitable for raising small-tailed Han sheep. Depending on the region, some areas are also suitable for raising Boer goats.

2. What are the key management techniques for raising small-tailed Han sheep?

1, castrate in time

Lambs used for fattening should generally be castrated within 1 ~ 3 weeks. At this time, castration is beneficial to improve the meat quality, make the meat tender, reduce the smell of mutton, and make the sheep docile, easy to manage and easy to fatten.

2. Early weaning

The traditional weaning time of small-tailed Han sheep is 3 ~ 4 months old. According to the experiment, under the same conditions, the average weight and daily gain of 60-day-old and 90-day-old weaned lambs are basically close to 6 months old, and the difference is not significant. This shows that early weaning at the age of 2 months is feasible. Weaning and fattening at the age of 2 months is beneficial for ewes to breed in advance, so that the breeding sheep can be raised from 3 births in 2 years to 2 births a year, thus improving the reproductive rate, slaughter rate and meat yield of small-tailed Han sheep.

3, regular deworming

For fattening lambs, deworming is carried out once after weaning and autumn. Commonly used anthelmintics include nitrochlorophenol, thiodichlorophenol and albendazole. 4 mg, 35-75 mg and 2.5-3 mg per kg body weight were taken orally.

4. Fine house feeding

The traditional extensive feeding method is fine assault fattening in the house, and the reasonable combination of coarse and fine feed can make lambs slaughter for about half a year, which can significantly improve economic benefits. Specifically, lambs weaned for 5-6 months were fattened with a compound feed of 35% green hay, 37% corn stalk powder, 5% bean cake, 4% cotton cake and 14% corn, with a live weight of more than 40 kg and an average daily gain of more than 200 grams.

5. Slaughter in time

The growth intensity of small tail Han sheep is high in the early stage and slow down in the later stage. If lambs are raised to 1 year old and then slaughtered, the feeding cost will be high and fat will be deposited. Therefore, it is best to fatten lambs at the age of 5 ~ 6 months.
