Ten tips for rapid fattening of mutton sheep

The rapid fattening of mutton sheep can make the lambs out of the fence for 2 months, the body weight reaches 1520kg, and the survival rate is more than 98%. In the management technology, we must grasp the following tips.

1. Select improved varieties. That is, to select the best hybrid combination of sheep and make full use of the heterosis to increase yield. For example, the meat goat cultivated by using Boer goat as male parent and local white goat as female parent has the characteristics of large size, stable genetic performance, high reproductive performance, strong disease resistance, high meat production rate, white wool, good luster, good elasticity and so on.

2. Build an enclosure. The construction of the mutton sheep enclosure should be warm in winter and cool in summer, and should be built in a place with high and dry terrain, good drainage and ventilation, clean and sanitary, with a half-slope type sitting in the north Chaoyang, with a general rear wall of 1.8 meters and a front eaves of 2.2 meters, and an external sports ground to create a good living environment for fattening sheep.

3. Raising ewes. Ewes should graze on high-quality pastures or mountain pastures, or feed them to high-quality forage grass. At the same time, each ewe was fed 0.4 kg to 0.7 kg mixed concentrate every day. The composition of mixed concentrate feed: corn 60%, wheat bran 8%, cottonseed cake 16%, soybean meal 12%, salt 1%, calcium hydrogen phosphate 3%.

4. Choose lambs for fattening. The lambs with large size, good development, strong feeding ability and disease-free were selected from the lamb flock to form the fattening group after weaning. It is best to choose male lambs because they grow fast and do not reach sexual maturity at this time.

5. Supplementary feeding of lambs. Cereal feed can be used with appropriate amount of soybean cake (meal), or mixed concentrate feed can be used, such as 45% corn, 22% wheat bran, 30% soybean meal, 1% salt and 2% fish meal. The amount of concentrate feed of lambs increased with the increase of age. At the age of 20-30 days, the feeding amount of each lamb was 50-70 grams, 100-150 grams at 1-2 months old, and 200 grams at 2-3 months old, twice a day.

6. cut off the tail at the right time. Lamb tail amputation can accelerate the growth of mutton sheep, improve meat quality and reduce the taste of meat. The tail of lambs can be cut off at 2-21 days old, but the most suitable age is 2-7 days old. It is best to break the tail in the morning on a sunny day. Methods: the tail of ① glue was broken. The elastic rubber tendons were placed between the second and third caudal vertebrae of the lambs, so that the lower part of the tail could not get nutrition and atrophied, and it fell off spontaneously after 10 days. ② cut the tail with a sharp knife. First tie the tail root with a string to cut off the blood flow, then cut it off 4cm away from the tail with a sharp knife and wrap it with gauze. In the afternoon, the tie can be untied and cured after 5 to 7 days.

7. Castration to promote growth. Castration of male lambs is generally carried out at the same time as tail amputation, and glue bar method and operation method can be used. The commonly used gluing method is to squeeze the testicles of 7-day-old lambs into the scrotum and tightly entangle the spermatic cord with glued tendons in the scrotum. After 20-30 days, the scrotum and plug pills will dry up and fall off naturally.

8. Disinfect in time. In the feeding and management of mutton sheep, there should always be adequate and clean drinking water supply, the house is well ventilated, the ground is dry, bedding grass is laid, and the feed is not polluted. Frequently clean and disinfect the sheepfold, sheepshed, material trough and sink; put the mat grass, forage grass and utensils for lambing in the sun frequently; boil and disinfect the overalls and medical instruments frequently.

9. Prevention of diseases. According to the epidemic characteristics of local sheep disease, adhere to the feeding principle of "prevention is more important than treatment", and carry out drug prevention and immunization to sheep in a planned way to prevent the occurrence of infectious and parasitic diseases.

10. Choose the right time for the hurdles. When the fattening sheep is full and strong, the fattening sheep can be fattened in time according to the market situation, which can not only shorten the fattening period of mutton sheep, but also improve the economic benefits of sheep farmers.
