At present, the sheep-raising industry is quietly gradually developing from sheep-raising in the pastoral areas to the agricultural areas. However, it is difficult for the traditional farming areas to rely on the extensive management of natural sheep to obtain maximum economic benefits. Therefore, with the rapid and large-scale development of the sheep farming industry in the agricultural area, combined with the introduction of fine varieties, the following six kinds of practical techniques that are convenient for operation and control are vigorously promoted, which can greatly increase the economic benefits of raising sheep. Promotion of artificial insemination technology 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. Promotion of economic hybrid use of high-quality meat rams and local ewes to carry out binary or ternary crossbreeding, production of superior hybrid lambs, fattening production of commercial mutton sheep. 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. Promotion of lamb supplementation and early weaning Lambs to several weeks of age, the ewes milk can not meet their nutritional needs, so early training lambs to eat and feed, supplement feeding. Generally start from 7 to 10 days of age, 15 to 30 days of age to feed 50 to 70 grams, 30 to 60 days to reach 100 grams, 60 to 90 days to reach 200 grams, to ensure that the lamb live full and fast growth , laying 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. Promote forage processing and modulation Feeding sheep Traditional sheep feeding Forage grass is often not processed by any processing. For example, corn stalks are mostly fed with whole plant dry stalks. This results in low digestion and utilization after feeding, which not only results in great forage resources. Waste, and the sheep grow slowly, long feeding cycle, slaughter rate is low, it should be widely promote silage, ammoniation, fermentation and other feed modulation processing technology to improve the economic benefits of sheep. Promotion of facilities for breeding In the past, farmers used sheep to raise sheep in the open air for raising sheep. 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 build a sheep house or warm house with a reasonable layout. In this way, the sheep has a comfortable living environment in both summer and winter, promoting its rapid growth and weight gain. And 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. The promotion of comprehensive disease prevention and control technologies is a major threat to the production of sheep. It should focus on the prevention of vaccination against infectious diseases, adhere to the principle of prevention, and regularly remove the parasites inside and outside the sheep, and pay attention to the sanitation and disinfection of the pens. Management often observes whether the sheep's spirit, diet, and feces are normal, so that no illness can be prevented early, and the disease can be found early and treated early.
Insect pheromones are compounds used by insects to represent various information such as aggregation, foraging, mating, and alerting. They are the chemical molecular language of insect communication. At present, the basic control measures for pests in agricultural production mainly rely on chemical pesticides, but the long-term uncontrolled use of chemical pesticides has brought many side effects. The first is the emergence of pest resistance, which causes the use of drugs and drug concentrations to increase, the cost increases year by year, and the prevention and control of increasingly difficult; the second is to disrupt the ecological balance, while controlling a large number of natural enemies were killed, causing the pupae of secondary pests; Third, it pollutes the environment. A large amount of pesticides remain in crops, soils, rivers, lakes, and seas, and they are enriched in the human body through the form of food chain, causing another harm to humanity. Therefore, relevant research departments in many countries are currently working hard to explore and study new approaches and technologies for pest control. These studies include: the development of new, efficient, environmentally friendly, low-toxic, low-residue chemical pesticides; natural enemy insects and microorganisms The use of pesticides; insect sterilization technology and the application of insect hormones; among them, the research on the use of insect hormones, especially insect sex pheromones for pest control, is receiving increasing attention and attention.
Research on insect pheromone has been developing rapidly. Since the first insect pheromone Bombykol, has been isolated and identified, more than 2,000 insect pheromones and their analogs have been identified and synthesized worldwide, of which more than 100 insect pheromone To achieve commercial production, the production and research of Lepidoptera sex pheromones is the most extensive and comprehensive.

Six new technologies to improve the efficiency of raising sheep
Pheromone is a collective name for compounds that play a role in chemical communication between organisms, and which is the chemical molecular language of insect communication. Including sex pheromone, collection pheromone, alert pheromone, tracking pheromone, altruin, altruin, synergistic pheromone, evacuation pheromone. Pheromones are chemical substances that interact with each other and can affect each other's behavior, habits, and even development and physiological activities. Pheromone is produced by the glands in the body and is directly discharged to the outside. The pheromone is transmitted to other individuals by means of air, water and other conductive media. Pheromones are found in lower animals and higher mammals. Because the pheromone is transmitted by the external environment, it is also called pheromone. Chemical substances that interact between different species are called interspecies pheromones or heteropheres.
