The purpose of goat farming is to sell fattening goats. The advantages and disadvantages of fattening goats depend on the length of time, the fat rate and the slaughter rate. Therefore, it is necessary to scientifically raise the fattening in the goat breeding, compress the breeding time, increase the slaughter rate, and increase the breeding efficiency. 1 Lamb fattening 1.1 Well-fat feeding and early supplementation of goats should be carried out by lambs. According to the characteristics of rumen function development of lambs, lambs can be fed around 10 days of age with high quality green hay, good palatability, oil cake, or The pellet feed made from formulated feeds induces lambs to learn to eat in the trough and start feeding early to promote the development of the gastrointestinal tract and increase the digestive capacity of the lambs. At the age of 20 days, the rumen begins to have a functional activity. The lamb can feed a certain amount of solid feed and can gradually increase the feed. 1.2 Implementation of early weaning As the lamb grows up, its energy, protein, etc. increase; the quality of the ewes' milk is reduced, which does not meet the growth needs of the lamb. Therefore, early feeding, weaning as soon as possible, so that the lamb to eat high-quality hay and nutritionally comprehensive quality feed. Weaning at 6 weeks of age ensures that the lambs eat and feed to meet their growth needs. 1.3 Restricted lactation Restrictive nursing was conducted 2 weeks before weaning of the lamb, gradually increasing the amount of hay and concentrate feed. Hay uses high-quality leguminous and grass hay; concentrates use jade, wheat and soybean cakes, and the protein content is more than 16%. Every day, the lambs and the ewes are separated from each other, restrictively breastfeeding, and the lambs are given as much as possible to eat hay and concentrate feeds to prevent early weaning from affecting the growth rate of the lambs. 1.4 Disinfection and Immunization at Weaning Before the lambs are weaned and fattened, they must clean and disinfect the environment and feeding management equipment in the finishing houses. A sheep shuttle enterotoxemia vaccine was injected when the lamb was weaned. 1.5 After the weaning, males and females feeding the general male and female lambs have certain differences in growth, and there are also differences in the demand for energy proteins. In general, the protein requirement of female lambs is about 2% lower than that of male lambs. With sexual maturity, such as the male lamb does not castrate, the latter will affect the group because of a good fight. At this time must be grouped feeding, respectively, with the feed, to ensure the nutritional needs of the lamb, and maintain the same growth. 1.6 After castration, the male lambs are castrated at about 20 days after supplementation, so that they are not affected by the subsequent growth and can grow rapidly. If there is no castrated male lamb, it will affect the growth and fattening due to sexual maturity during the late period of fattening. 2 Fattening sheep ration science equipment 2.1 Fattening sheep's nutrients The goat fattening effect mainly depends on its feed intake. According to the nutritional requirements of goats, a reasonable diet should be provided to provide enough nutritious feed for sheep to feed freely. It has been proved by practice that the whole grain material has better fattening effect than the crushed grain material, and the compound feed has a better fattening effect than the single grain feed, mainly because the feed conversion rate is high and the gastro-intestinal disease is less. The following feed recipes can be referenced: 83% whole corn, 15% soybean cake, 1.4% limestone powder, 0.5% salt, and 0.1% vitamins and trace elements. Among them, the added amount of vitamins and trace elements was calculated per kilogram of feed: vitamins A, D, E were 5 000 mg, 1 000 mg, 200 mg, cobalt sulfate 5 mg, and potassium iodate 1 mg. 18% peanut cake can also be used instead of bean cake, and the proportion of corn is adjusted to 80%. 2.2 Timely adjustment of dietary protein content Crude protein and energy intake are most important for the growth and development of goats. Sufficient high-energy and protein feed should be provided to maximize the sheep's maximum production potential. Different fattening stages have different protein requirements, and the protein content of the diet should be adjusted according to the rate of weight gain. The 16% protein diet was generally used from the weaning period of 6 weeks to 90 days, and to 14% of protein diets after the 90 days of slaughter. If the fattening weight reaches 40 kg, the protein can be reduced to below 12%. 2.3 Timely supplement of calcium In diets for fattening sheep, vitamins and trace elements are indispensable. The content of phosphorus in the concentrate is relatively abundant, so pay attention to calcium in order to balance the calcium and phosphorus and avoid the generation of urinary stones. 3 Phase-out of adult sheep fattening 3.1. Repelling and immunizing For the fattening of obsolete post-residue sheep, deworming and immunization are required. A thorough deworming of the parasites in vivo and in vitro and in the blood source should be carried out. After one week of deworming, the body of the sheep is recovered and then immunized. 3.2 Gastrointestinal supplementation After eliminating the insecticides of the displaced old sheep, it is necessary to intensify the administration of Jianwei Xiaoshi drugs to promote appetite, increase the intake of feed, and make up the feed. The fattening is based on providing energy feeds to ensure that sheep can only quickly increase fat. It is generally required that roughage account for 30% to 60% of the diet and increase the amount of corn in the mixed concentrate. When straw crops and agricultural and sideline products are fed, they must be shortened or made into grass powder to improve digestibility and feed conversion efficiency. There must also be a certain amount of carrots and other juicy feeds in the diet. 4 timely slaughter By using the optimal growing period for lambs for fattening, goats must be slaughtered for a certain period of time before they can be fed for a long time. Because the goat's growth rate begins to decline after sexual maturation, and both feed utilization and conversion are reduced. Lamb fattening until the late growth slows, will increase the breeding cost, reduce the breeding efficiency. Generally large varieties are slaughtered at 45-55 kg; medium-sized varieties are 30-40 kg, and small varieties are suitable for slaughter of 20-30 kg.
