The sheep industry is gradually shifting from the pastoral areas to the farming areas. However, it is difficult to obtain large economic benefits from the traditional extensive management of agricultural areas. Combining the introduction of excellent varieties, the following six kinds of new technologies that are convenient for operation and control are vigorously promoted, which can greatly increase the economic benefits of raising sheep.
First, artificial insemination
The promotion of this technology can greatly increase the utilization rate of breeding sheep, reduce the number of breeding rams, and save the cost of feeding and the purchase of excellent rams. In addition, the excellent rams are expensive and are currently at more than 10,000 yuan each. If the breeding method is used, breeding of cross-infection and spreading of certain diseases will be easily caused, and the rams will lose their breeding ability. The basic ewes lose their species. Use value.
Second, lamb supplementation and early weaning
After the lamb is a few weeks old, the ewes' milk can no longer meet their nutritional needs. Therefore, the lambs must be trained early to feed on the grass and feed. Generally start from 710 days of feeding, feed 5,070 grams on 1530 days, reach 100 grams on 3060 days, and reach 200 grams on 6090 days to ensure that the lamb is fully active, fast growing, and lays the foundation for early weaning and late fattening. . Early weaning is carried out at 100 days of age, and no more than 4 months of age at the latest. This shortens the gap between lambs and increases the number of fetuses born within the ewes' useful life.
Third, forage processing after feeding sheep
Traditionally, sheep feeding forage is often not processed. For example, corn stalks are mostly fed with whole plant dry stalks. This results in low digestive utilization after feeding, which not only results in great waste of forage resources, but also slows sheep growth. The cycle is long and the slaughter rate is low. Therefore, silage, ammoniation, fermentation and Other feed preparation and processing technologies should be widely promoted to increase the economic benefits of raising sheep.
Fourth, facility breeding
In the past, farmers used sheep-flies for raising sheep in the open air. The sheep tend to grow in summer, autumn, winter, and spring. Therefore, if you want to increase the efficiency of raising sheep, you should promote facility breeding and construct a sheep house or warm house with a reasonable layout. In this way, both in summer and winter, the flock has a comfortable living environment that promotes rapid growth and weight gain. The rational construction and layout of the breeding facilities can greatly reduce the occurrence of diseases. It is more economical to spend money on the building of a sheep house than to spend money on medicines and drugs. Moreover, excessive use of drugs can lead to drug residues.
V. Integrated Disease Prevention and Control Technology
Disease is a major threat to the production of sheep. It should focus on the prevention of communicable diseases and adhere to the principle of prevention. Regular expulsion of parasites inside and outside the goat, attention to the sanitation and disinfection of the pens, often observed in the daily management of sheep spirit, diet, feces, etc. are normal, so that no illness early prevention, early detection of disease, early treatment.
VI. Economic Hybridization
By using binary broilers or ternary crossbred male rams and local ewes, fine hybrid lambs are produced, and commercial mutton sheep are produced by fattening. Hybrid goats not only grow fast, but also have high feed rewards. They also have good meat quality, tenderness, high selling prices, and good economic returns.
