Boer goats are one of the finest breeds of meat goats in the world, and their hybrid offspring also show significant heterosis. In actual production, we have achieved significant results by combining the characteristics of the physiological development of goats with the use of concentrates and rapid fattening, according to the characteristics of the first generation of Boer goat hybrid lambs and the high growth rate. But in the fattening process should pay attention to the following questions: 1, the early feeding of hybrid lambs, a major birthstone, early growth and rapid development, the majority of local ewe lactation capacity can not meet their growth and development needs. In the production practice, we have adopted 7 to 10 days of age to start feeding (according to the lamb growth standard with the full price plus 15% milk, the material is mixed into a semi-wet material with a humidity of about 60%). When feeding, a special supplementary column should be set up, which can be quantified regularly, 4 to 5 times a day, and about 50% of each feed is fed. As the age increases, the amount of feed increases gradually and the spare time allows the lamb to move freely. At this stage, we must pay attention to prevent lamb diarrhea, the main measure is regular disinfection, ewes about 1 month before birth immunization four injection vaccine. If the lamb suffers from dysentery, even if it is cured, it will sometimes be repeated, directly affecting growth, and some may even form a "stiff sheep." 2. Early weaning lambs are generally weaned at 3 to 4 months of age. In order to improve the lamb's commodity productivity and shorten the breeding cycle of ewes, we use two months of weaning, the specific approach is: the two-month-old lamb, the ewes pulled out of the breeding circle to leave the lamb once weaning, at this time to pay special attention Shelter environment, keep quiet, according to the weather, pay attention to the temperature of the house, daily management should be kept unchanged, provide clean drinking water twice a day, to prepare for intensive fattening. 3, do a good job "two go" and pest control epidemic prevention "two to go" that is, go horn and male lamb cast. The dehorning is usually performed about one week after birth. The common method is to apply butter to the two corners of the lamb, scald with a soldering iron, and bleed to the corner base. Rams should be castrated 10 to 15 days after weaning. About half a month after weaning, we should also do a good job of epidemic prevention and deworming work. In order to prepare for rapid fattening, the epidemic prevention is mainly four-folded sheep seedlings, each with 1 ml of intramuscular injection. 4. Reasonable grouping, so-called rational grouping of fattening is divided into 10 small clusters of fattening according to sex, weight and body size. During the fattening process, a sufficient amount of clean drinking water should be provided. The complete finisher feed should be added with about 30% high-quality hay or full-finishing feed (500-700g/day) and then fed with high-quality hay to allow free extraction. Eat and feed three times a day. At this stage, observe the feed intake and condition of each sheep, and find that the problem is solved in time.
