How to improve the Survival rate of small tail Han Lamb

Small tail Han sheep in China's breeding area is relatively large, but also a sheep industry is more popular species. However, although the breeding area of small-tailed Han sheep is large, lambs often die when breeding small-tailed Han sheep, resulting in a relatively low survival rate of lambs. So how can we improve the survival rate of the lamb? The following small series will briefly introduce you, let's take a look together!

1. Female sheep management

The first estrus period of small tail cold sheep is relatively early, usually ewes in half a year when they can start estrus breeding. Among them, in spring and autumn for the estrus exuberant period, estrus should be timely breeding. The cycle is usually about 2-3 weeks, with an average of 18 days. If the first mating is unsuccessful, repeat mating is required. During pregnancy, management should be strengthened to provide about 3 kg of high-quality fresh grass every day, and corn, bran and other refined feeds should be properly supplemented. When grazing, pregnant sheep should be avoided from collision, and pregnant sheep should not be frightened to run, resulting in abortion.

2. Lamb Care

For newborn lambs, the mucus on the body should be removed in time, and the heat preservation should be done well when the temperature is low. And let the lamb eat colostrum as soon as possible, because colostrum is rich in nutrients, can enhance the lamb's immunity. If the ewes have too many litters and are not producing enough milk, do a good job of artificial feeding. After the lamb is born, it is necessary to strengthen the sanitation work in the house, and let the lamb eat and drink freely. Let lambs adapt to feed as soon as possible, promote rumen development.

3. Lambs weaned

To wean the lambs early, it is necessary to train the lambs 'feeding ability artificially. When lambs are half month old, some fresh grass should be fed properly to promote the formation of digestive tract function of lambs, so that lambs gradually transition to autonomous feeding direction. And in order to advance the lamb eating time, corn and bean flour and other foods can be mixed together to cook porridge for feeding in the early stage. Or you can fry the concentrate and put it in a basin and let the lambs lick themselves. Under normal circumstances, lambs can eat normally at about one month old.

4. Disease prevention

Lamb's own immunity is still relatively poor, prone to various diseases. Such as iron deficiency, selenium deficiency diarrhea and diarrhea. We have to use drugs appropriately according to the knowledge of professionals. A proper injection of lamb dysentery vaccine one month and half a month before delivery can effectively enhance lamb immunity. Within 10 hours after birth, lambs should be properly fed oxytetracycline once a day for about three times, which can effectively prevent dysentery. For sheep diseases, the principle of early detection and early treatment should be adopted, and corresponding measures should be taken in time after discovery.

The above is a simple introduction to how to improve the survival rate of small tail Han sheep lamb. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
