Boer goat crossbreeding
Boer goats breed non-seasonally and can breed estrus and breed lambs all year round. Ewes mature at 6 months of age, and due to the high levels of sex hormones in the fall, autumn is the peak period of sexual activity. The ram is mature at 6 months of age and the ewes reach sexual maturity from 6 months to 8 months of age, and the breeding period is long, and 8 to 12 lambs can be obtained in 2 years. In the case of grazing, 15 ewes are averagely bred; 30 ewes can be averaged over 9 months of age. The high lambing rate increases the yield per sheep and unit area. The economic traits of sheep are embodied in high-quality, high-yield livestock products, and they are highly profitable through the input-output ratio. The use of a Boer goat as a parent to improve local goats has obvious advantages in hybridization; the production performance of hybrid offspring can be increased by 30% to 60%. Therefore, the efficiency of goats can be greatly increased, which is of great significance for the transformation of the sheep industry from quantitative growth to quality improvement. Featured Ewe Because the birth weight and individual size of the crossbreeds of Boer goats are very high, if the ewes are too small or the ewes are born, it is easy to have dystocia. Once improperly handled, it will cause fetal disability or death. Therefore, when selecting ewes, the weight of the ewes should be more than 30 kilograms, and it is a ewes that have passed the production, have no reproductive disease, and have good breast development, so that the normal production of the fetus can be guaranteed. Screening source At present, purebred Boer goats are small in number and high in price. Some farms (households) use high-margin profits, and high-generation hybrids of Boer goats serve as purebred Boer goats for sale or breeding, resulting in poor growth performance of hybrid offspring. Meat characteristics are not obvious. Should choose reliable breeding farms to buy rams or semen, and require fresh essence vitality above 0.6, frozen essence vitality above 0.35 before mating. In addition, when purchasing sheep or frozen sperm, ask the manufacturer for a pedigree. Reasonable use The Boer goats have a small population and high cost. After purchasing the Boer goats, the sperm is diluted and then artificially inseminated. After breeding, the local ewe is mated with the local ewe so as to improve the utilization rate of the breeding sheep and ensure the improvement effect. In addition, Boer goat semen can be used to improve local goats. Although this method is easy to operate and is not limited by time and place, the conception rate is generally about 50%, and the effect is not good. Whether it is to adopt frozen semen breeding or breeding of fresh semen, strict operating procedures should be followed to grasp the best timing of insemination. Scientific feeding tube First of all, we must strengthen the feeding and management of ewe, to meet the nutritional needs of the fetus in the mother's different growth period, to ensure adequate postpartum milk. Second, the fetus should assist the fetus to eat colostrum as soon as possible after receiving contaminated food. Once again, the lamb began to replenish grass and concentrates after 10 days of age to strengthen gastrointestinal training and meet nutritional needs. In addition to the breeding and production of sheep, the traditional way of producing sheep is self-cultivation. Due to the different production purposes of breeding sheep and lambs, breeding sheep and weaning lambs should be reared in groups or separately. The breeding and management of the flock is more extensive than that of the lambs. The focus is to maintain the body condition, provide timely breeding, prevent missed allocation and miscarriage, and provide sufficient nutrition during the breeding period and gestation period; and the focus of the lamb feeding and management is to provide nutritious food throughout the process. Forage feed, pay attention to keeping warm and prevent disease. Repair sheep homes The sheds are required to face south to the south, have ample sunshine, air circulation, dry hygiene, and good thermal performance. They block the wind tunnel before the winter starts, ensuring that the roof is not leaking, all sides are not permeable, and the ground is not humid. For shabby, leaking, and ventilated sheep houses, repairs must be made in a timely manner. Into the winter, but also in the sheephouse outlet and vent hanging straw or cotton curtains to prevent the invasion of thieves. Strict prevention According to the prevalence of sheep disease in various places, the sheep will be well-prepared for vaccination with "No. 5 disease," "Tetanus," "Sheep pox," "Sheep Contagious Pleuropneumoniae," and "Triple Four Preventions." In addition, goats are regularly exterminated from both internal and external parasites, and sheep sheds, playgrounds, forage racks, and feeding troughs are disinfected with different disinfectants.
