If you buy Boer Goats, a generation of Boer goats use the original species, 2 litters per year or 3 litters per year, 2-3 lambs per litter, and the lambs produced are purebred 2 generations, raised from March to April. Only Boer goats are priced at around RMB 500. Three Boer goats are priced at RMB 1,500. If calculated by two nests, they are RMB 3,000. Then one generation of Boer goats is removed and the forage is removed. The net profit for labor expenses is no less than 2,000— 2,500 yuan, if the investment is big, the benefits of purchasing the second-generation and third-generation will be even more impressive.
Boer goat is recognized as an excellent meat species in the world, with large individuals, rapid growth in the initial stage, wide adaptability, good reproductive performance, and high meat yield. (For details, please refer to the introduction of Boer goats' production performance.) . Since the original species of the Boer goats were introduced from abroad and the relative prices were relatively expensive, the prices of original species and pure breeds introduced and returned for breeding were relatively high. Therefore, for farmers' friends, the initial investment in the use of the following modes of moderately small-scale operations, adopting the idea of ​​building rolling construction alongside production, and gradually building a small-scale sheep farm around the radiation. Feeding 1-2 adult Boer rams If you buy Boer goats, a generation of Boer goats use their original species, 2 litters per year or 3 litters per year, 2-3 lambs per litter, and the lambs produced are purebreds. For 2 generations, from March to April, a Boer goat sells for around 500 yuan, 3 goats sell for 1500 yuan, and 2 nests cost 3,000 yuan. Then raises a generation of Boer goats and removes fodder. The net profit of artificial expenditure is no less than RMB 2000-2,500. If the investment is big, the benefits of buying the second-generation and third-generation generations are even more impressive.
(1) Establish a ram breeding station. Breeding adult male rams to breed ewes for neighboring farmers Breeding lambs for the sheep is a hybrid sheep of the Boer sheep. Farmers can also obtain more income than raising ordinary goats. Under normal circumstances, an adult ram can be planted 2-3 times a day, for example, once every 4 days, an average of 24 days can be used in a month, and an average of 60 times a month can be naturally bred. At present, Boer ram breeding fees are 100 yuan in some areas, Shandong is generally 40 yuan/time, such as an average of 30 yuan, at least 1,800 yuan a month, deducted four months of high temperature weather in a year, a year-round Adult male rams gained nearly 15,000 yuan. When the investment was made that year, it was recovered and the net ram was grown and used again in the coming year.
(2) Establish an artificial insemination service station. Artificial insemination technology is the use of appropriate equipment to collect semen of the species of sire, after quality inspection, dilution and preservation, the qualified semen in the female genital tract in the timely use of the device to replace the male and female animals directly mating and pregnant. Under normal circumstances, an adult male ram can collect 1 time a day, and if it takes a break every 4 days, 24 times a month on average. A spermatorrhea can normally be used to prepare fresh and refined 15-20 sticks. At present, the use of fresh essence for artificial insemination package matching pregnancy (normal use of fresh essence matching need to be equipped with 2 times) charges 10 yuan / first time, an adult ram can make a profit of 100 a day RMB 2,400 per month, deducting 4 months of high-temperature weather in one year, and earning 19,200 yuan a year. In the year when the investment was recovered, and the appropriate surplus and net were obtained as an adult ram, the ram would continue to use it in the coming year.
(3) Combination of breeding services and hybrid sheep production. Feeding breeding rams in the same manner as described in 1 or 2 above, breeding local ewes and breeding them with porcine rams for hybrid sheep production (this method is particularly suitable for the majority of sheep-raising households or sheep-raising households); Native female goats, calculated on an annual output of 2 tires, averaged 4-6 lambs, local goats weighed 26.3 kg for 12 months, 5 lambs weighed 131.5 kg, slaughtered 32.7%, and received 43 kg of mutton to 12 yuan Calculated per kilogram, total income is 516 yuan. For example, in the crossbreeding of Boer goats, in the same five lambs, each weighing 64.9 kilograms for 12 months, five lambs weighed 324.5 kilograms, the slaughter rate was 46.8%, and 151.87 kilograms of mutton were obtained, which was calculated at 12 yuan per kilogram. Total income 1822 yuan. In the case of raising a single ewes each year, the use of Boer goats can lead to an income of 1,306 yuan. Increase economic efficiency by 2.35 times. For example, 10 ewes per household can earn more than 13,060 yuan per year. In farming in the countryside, there is almost no cost for forage, condiment, and human consumption. Through the above analysis, raising a head of a sheep is better than planting 10 acres of land. Everyone has the opportunity. Whoever invests early will benefit early and never miss an opportunity.

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.
