Summary: The small-tailed cold sheep is a breed of sheep with meat and fur in China, which has the characteristics of long-term development, early maturity, strong fertility, stable performance, strong adaptability, etc., and is designated by the state as a famous breed of livestock, which is not only one of the best projects for farmers to get rid of poverty and become well-off, but also the most stable project of the government's poverty alleviation work, let's take a look at where the small-tailed cold sheep is suitable for raising it!
Small-tailed cold sheep is China's meat and fur combined use of sheep breeds, with long development and fast development, early maturation, strong fertility, stable performance genetics, strong adaptability and other breeding characteristics, by the state as a famous breed of livestock, is not only one of the best projects for farmers to get rid of poverty and get rich, but also the most stable project of the government's poverty alleviation work, let's take a look at where the small-tailed cold sheep is suitable for raising it!
Where is the small-tailed cold sheep suitable for raising?
Although the small-tailed cold sheep is a Mongolian sheep family, because it has developed the habit of "house feeding and captivity" in the southwest region of Lu for thousands of years, natural conditions such as sun, rain and cold can be regulated by the pen, and are rarely affected by regional climatic factors. It can be raised all over the country, from Heilongjiang and Inner Mongolia in the north to Guizhou and Yunnan in the south, it can grow, develop and reproduce normally, and all areas that do not violate the special living habits of Xiaowei Cold have been successfully raised.
Environmental conditions for the breeding of small-tailed cold sheep
It is produced in southern Hebei, eastern and northeastern Henan, southern Shandong and northern Anhui and northern Jiangsu, mainly distributed in Caoxian, Wenshang, Liangshan and other counties in Shandong Province and parts of northern Jiangsu, northern Anhui and Henan, with low terrain, fertile soil and mild climate. The average annual temperature is 13 to 15 °C, January is -14 to 0 °C, July is 24 to 29 °C, the annual precipitation is 500 to 900 mm, and the frost-free period is 160 to 240 days. The main production area is one of the main production areas of wheat, grains and cash crops in China, crops can be cooked twice a year or three times a year, rich in agricultural and sideline products, providing a large amount of forage feed for sheep.
Breeding management techniques for small-tailed cold sheep
1, timely castration: lambs used for fattening should generally be castrated within 1 to 3 weeks, at this time to remove stoning is conducive to improving the quality of meat to make the meat tender, reduce the taste, and make the sheep docile, easy to manage, should be easy to fatten.
2. Early weaning: The traditional weaning time of small-tailed cold sheep is mostly 3 to 4 months old. According to the test, lambs weaned at 60-day-old and 90-day-old were fattened under the same conditions to 6 months old, and the average weight and daily weight gain of the two were basically close, and the difference was not significant. This suggests that early 2-month-old weaning is feasible. Weaning and fattening at 2 months old is conducive to the early breeding of ewes, so that the breeding sheep is increased from 3 births in 2 years to 2 litters a year, thereby improving the reproduction rate, pen yield and meat production of small-tailed cold sheep.
3, regular deworming: for fattening lambs after weaning and in the autumn are dewormed once, commonly used deworming drugs are nitrochlorophenol, thiobichlorophenol, propylthioidazole, etc., each kilogram of body weight with 4 mg, 35 ~ 75 mg, 2.5 ~ 3 mg orally.
4, house feeding fine: feeding by the traditional extensive feeding method for the house feeding fine surprise fattening method, the coarse and refined feed reasonable collocation, so that lambs about half a year out of the pen, can significantly improve economic benefits. Specifically, 35% of green hay, 37% of corn straw, 5% of soybean cake, 4% of cotton cake and 14% of corn can be used to fatten weaned lambs 5 to 6 months old, with a live weight of more than 40 kg and an average daily weight increase of more than 200 grams.
5. Feeding additives
(1) Feeding sheep fattening compound feed: This additive is composed of trace elements iron, copper, manganese, zinc, selenium, rumen metabolism regulator, growth promoter and harmful microbial inhibition substances, suitable for the year of karma lamb and the elimination of old sheep fattening, feeding this additive weight gain rate and feed conversion rate increased by 23.1% and 18.7% respectively.
(2) Feeding rumen: the role is to control and improve the efficiency of rumen fermentation to improve the weight gain rate and feed conversion rate. The test proved that the daily weight gain of the small-tailed cold sheep fed rumen was about 35% higher than that of the control group, and the feed conversion rate was increased by 27%. Small-tailed han sheep add 25 to 30 mg of rumen per kilogram of diet. In practical application, the appropriate amount should be determined according to the composition of the diet, and it should be evenly mixed in the feed, and the initial amount can be lower, and then gradually increased.
(3) Feeding urea phosphate: the role is to supplement nitrogen and phosphorus in ruminants, which is a new type of non-protein nitrogen feed additive, adding about 10 grams of urea phosphate per sheep per day, and the average daily weight gain is increased by 26.7%.
(4) Feed bacitracin zinc bacteriostatic growth promoter: the effect on animals and is conducive to the digestion and absorption of nutrients in the intestine, improve the utilization rate of feed, and increase weight. Lambs are fed 10 to 20 mg per kg of mixture and mixed in the feed.
6, timely slaughter: small tail cold sheep in the early stage of growth intensity, late growth becomes slower, if the meat with lambs raised to more than 1 year old and then slaughtered, high feeding costs, fat deposits. Therefore, the rapid fattening period of lambs should be 5 to 6 months old.
