The small-tailed cold sheep has always been known as the "national treasure sheep", which has the advantages of large size, high reproductive rate, fast growth rate, etc., but many sheep farmers cannot raise the small-tailed cold sheep well, such as the poor quality of the small-tailed cold sheep population, poor breeding management conditions, poor lamb weaning survival rate, etc., which in turn makes the sheep farm benefit and output low. Today Xiaobian introduces you to the 5 points of efficient breeding of small tailed cold sheep, hoping to help the majority of sheep farmers and friends.
1. Selected populations
Although the small-tailed cold sheep is an excellent breed, there are also large differences between individuals, and sheep farmers need to continuously select the population. A good small-tailed cold sheep must meet the following requirements, 6-month-old male lambs need to reach more than 100 pounds, female lambs need to reach more than 80 pounds, adult rams should weigh more than 260 pounds, adult ewes should weigh more than 160 pounds, and the fertile ewe should be able to meet the requirements of 3 births in 2 years and at least 2 lambs per birth. Of course, for sheep farmers to select the population is a long process, but only when there is a high-quality population can produce a large number of lambs of good quality, in order to obtain higher efficiency output, so sheep farmers need to constantly select the population to improve the quality and efficiency of the population.
2. Supporting hybridization
Although the small-tailed cold sheep are relatively excellent in terms of body shape, reproductive performance, growth rate, etc., there is still a big gap compared with specialized meat sheep (such as Dubo sheep, Suffolk sheep, etc.) in terms of feed conversion rate and slaughtered meat rate, so in order to obtain higher efficiency output, a supporting hybrid system should be used to produce commercial sheep. Sheep farmers generally use the binary hybridization model, that is, the use of small-tailed cold sheep as the mother, Dubo sheep or Suffolk sheep as the father of the direct hybridization, which can not only ensure a good reproductive rate, but also improve the feed conversion rate and slaughter meat rate of offspring commercial sheep. In order to further improve the efficiency of output, you can select a more fertile generation of hybrid mother lambs as the mother, and then use the Dubo sheep or Suffolk sheep as the parent for progressive hybridization or ternary hybridization, so that the production performance of the produced commercial sheep will be further improved.
3. High-precision breeding
Small-tailed sheep are large, have a high reproductive rate and a fast growth rate, so they have higher nutritional requirements, and if they only use a single grass with low nutritional value for feeding, it is easy to make it malnourished, which in turn affects its reproduction rate, growth rate and even health. Small-tailed cold sheep should adopt a high-precision feeding method, grazing ewes feed at least 0.3 kg of concentrate per day, house-fed ewes feed at least 0.5 kg of concentrate per day on the basis of ensuring adequate supply of coarse forage, and fattening lambs should not feed less than 1% of their body weight per day. The concentrate needs to be scientifically and reasonably matched to achieve a comprehensive and balanced nutrition, with reference to the combination scheme corn 58%, soybean meal 24%, wheat bran 12%, premix 4%, calcium carbonate 1.2%, salt 0.8%.
4. Fine management
The small-tailed cold sheep also needs refined management, including breeding environment, breeding and breeding, epidemic prevention and deworming, etc. The small-tailed sheep are not very suitable for complete livestock and captivity, and it is best to graze regularly when conditions permit, and build a larger sports field for their free activities if conditions do not permit. The manure in the sheep house and the sports field is cleaned in time and disinfected regularly, and the sheep house is ventilated and cooled in summer, and the cold insulation measures are taken in winter. Do a good job of breeding records, do a good job of nursing the ewe during pregnancy, and do a good job of prenatal and postnatal care of ewes. Formulate scientific and effective epidemic prevention and deworming plans, and strictly follow the plan to prevent and deworm sheep.
5. Raise dairy sheep
Small tail cold sheep produce more lambs, the number of individual ewe fetal lambs can reach 3 to 4 or even more, and the small tail cold sheep under normal circumstances only enough milk production is only enough for 2 to 3 lambs to eat, once the lambs can not eat enough milk will affect the normal growth and body resistance, so it is best to raise some dairy goats in the case of raising small tail cold sheep, generally speaking, 5 to 8 small tail cold sheep supporting the breeding of 1 dairy goat. Lambs eat some colostrum after birth, and then let the dairy goats act as nanny sheep to breastfeed the lambs, and a dairy goat at the peak of lactation can bring 4 to 6 lambs. If there is no supporting breeding of dairy goats, when the ewe produces too much milk, it is necessary to carry out artificial breastfeeding, and when artificially breastfeeding the lamb, it must be timed, quantitative, temperature-fixing and qualitative, so as to avoid diarrhea caused by the discomfort of the lamb.
