There are ways to breed Boer goats.

Boer goat, which originated in South Africa, is known as the "king of meat goats" in the world. It is a famous goat producing high quality lean meat in the world. It is an excellent breed of meat goat. It has the characteristics of large size, fast growth, strong fecundity, more lambs, high slaughtering rate, high meat yield, delicate meat quality, good palatability, rough feeding resistance, strong adaptability, strong disease resistance and stable heredity.

The age at which male and female lambs have their first estrus after birth is called proestrus, which is usually called sexual maturation. At this time, secondary sexual characteristics have appeared, which can produce mature germ cells (sperm or eggs) and have the ability to reproduce, but they are not suitable for immediate breeding. The first estrus of Boer goat female lambs is usually 6-8 months old, and the weight reaches 40% of the annual sheep. 60%. The ram has sexual behavior when it is 4 months old, such as climbing, it can excrete sperm. However, because the reproductive organs of male and female sheep are not fully mature at sexual maturity, early mating is disadvantageous to the growth and development of themselves and their offspring. Therefore, the first mating age of Boer goats is generally more than 10 months old, and the first mating age of rams is more than 12 months old.

Boer goats are non-seasonal breeding livestock and can breed lambs in estrus all the year round. Ewes mature at the age of 6 months. Due to the high level of sex hormones in autumn, autumn is the peak of sexual activity. The male sheep matured at the age of 6 months, and the ewes reached sexual maturity at the age of 6 months to 8 months, and the mating period was long. 8 ~ 12 lambs could be obtained in 2 years. Under the condition of grazing, an average of 15 ewes were bred, and over 9 months old, an average of 30 ewes were bred. The high-yielding lamb rate increased the meat yield per ewe and per unit area. The economic characters of sheep are high-quality and high-yield animal products, and high benefits are obtained through the ratio of input to output. Using Boer goats as male parents to improve local goats has obvious heterosis, and the production performance of hybrid offspring can be improved by 30% and 60%. Therefore, it can greatly increase the benefit of goats, which is of great significance for the transformation of sheep industry from quantity growth to quality improvement.

Selected ewe

Because the hybrid offspring of Boer goat are born heavy and large, it is easy to have dystocia if the ewe is too small or give birth to ewes. If it is not handled properly, it will cause fetal disability or death. Therefore, when selecting ewes, ewes weighing more than 30 kilograms should be selected, and ewes with postpartum, non-reproductive diseases and well-developed breasts should be selected to ensure the normal production of the fetus.

Screening provenance

At present, the number of purebred Boer goats is small and the price is high. In order to make high profits, some farms (households) use the high generation hybrid offspring of Boer goats as purebred Boer goats to sell or mate, so that the growth performance of hybrid offspring is poor and the characteristics of meat use are not obvious. Reliable breeding farms should be selected to buy breeding rams or semen, and only when the vitality of fresh semen is more than 0.6 and that of frozen semen is more than 0.35 can it be mated. In addition, ask the manufacturer for genealogy when buying breeder sheep or frozen semen.

Rational utilization

Boer goat has few stockpiles and high cost. After purchasing Boer goat ram, the method of artificial insemination after semen collection and dilution of original semen was used to breed with local ewe to improve the utilization rate of breeding sheep and ensure the effect of improvement. In addition, Boer goat frozen 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 satisfactory. Whether it is frozen semen or fresh semen, the operation rules should be strict and the best time for insemination should be grasped.

Scientific feeding tube

First of all, it is necessary to strengthen the feeding and management of ewes to meet the nutritional needs of fetuses in different growth periods in the mother, and to ensure adequate postpartum milk. Secondly, after delivery, the fetus should be assisted to eat enough colostrum as soon as possible, and the lambs with insufficient milk should be replenished by artificial milk. Thirdly, after 10 days of age, the lambs began to supplement grass and concentrate to strengthen gastrointestinal exercise to meet their nutritional needs. In addition to breeding sheep, the traditional way of mutton sheep production is self-breeding. As the production purposes of breeder sheep and lambs are different, breeder sheep and weaned lambs should be raised in groups or households. The feeding and management of breeder sheep is more extensive than that of lambs, the key point is to maintain the physical condition of breeding, timely mating, prevent mismatch and abortion, and give adequate nutrition during mating and pregnancy, while the focus of lamb feeding and management is to provide nutritious forage throughout the process, pay attention to cold protection, warmth and disease prevention.

Repair the sheep house

The sheep house is required to sit north and south, sunny, well-ventilated, dry and hygienic, and keep warm. The Beginning of Winter clogs the wind tunnel in front of him to ensure that the roof is not leaking rain, the four sides are airtight, and the ground is not wet. Sheep sheds that are dilapidated, leaky and ventilated should be repaired in time. In the cold winter, grass curtains or cotton door curtains should be hung at the exit and ventilation of the sheep barn to prevent the invasion of thieves.

Strict epidemic prevention

According to the epidemic situation of sheep disease in various places, we should do a good job in vaccinating sheep with "No. 5 disease", "tetanus", "sheep pox", "sheep infectious pleuropneumonia" and "three combinations and four prevention". In addition, regularly remove parasites in vivo and in vitro, and disinfect sheep houses, sports grounds, forage racks and grooves with different disinfectants.
