1 The selection of elite male parents should choose varieties with large individuals, fast growing speed, wide recipes, high feed (grass) rewards, good meat performance and meat quality, high slaughter rate, and strong adaptability. Saanen goats are often used as the first male or Boer goats for the first and second male parent in production. The number of local mothers, high reproduction rate, resistance to roughage, and strong adaptability must be selected for breeding, purification and rejuvenation. 2 To determine the hybridization pattern goat hybrids are binary hybridization, three-way hybridization and progressive hybridization. If farmers are breeding local goats, Saanen goats or Boer sheep rams can be introduced for binary crossbreeding. The hybrid rams are all fattened. The hybrid ewes can be fattened and can also be used as seedlings to crossbreed with Boer goats. Among them, the cross between the Sabine binary ewes and the Bol rams is called a three-way cross, and all the crossbreds are fattened; the cross between the bougainvillea binary ewes and the polo rams is called the advanced binary crossbreeding, and the Posabbon The ternary crossbred ewes are then hybridized with the Bol rams and called triad hybrids. From the perspective of hybridization, three-way hybrids are superior to binary ones, and triad hybrids are superior to three-way hybrids. 3 Grasping the moderate scale The scale of meat goat farming depends on many factors such as the investment ability, market price, forage area, feeding and management conditions, and the proportion of male and female farmers. Practice has shown that the minimum size of rearing hens should not be less than 20, and the appropriate size should be 40-50. For specialized large households specializing in fattening lambs, it is advisable to control the breeding scale from 100 to 150. 4 Reasonable group rearing Due to the different production purposes of breeding sheep, pregnant ewes and lambs, there are different requirements for forage quality and feeding and management conditions. Polyculture tends to cause lack of nutrients for lambs, prolonging the period of fattening, and thus increasing the cost of rearing; The rams mess with each other, affect their utilization, and even lead to the overall degradation of the sheep. Therefore, farmers should rationally group herds according to their purpose, requirements and age structure. 5 The construction of high-bed sheep collar slatted floor sheepfold has the advantages of drying, ventilation, and easy removal of feces, which can greatly reduce the occurrence of goat diseases. The height of the slatted floor from the floor is 30 to 50 cm. The wooden plates and bamboo sheets can be used for the plates. The distance between them is about 3 cm. In winter, a wooden sheep bed should be placed on the slatted floor for the sheep to lie down. At the same time, it is necessary to teach goats to excrete feces at regular intervals to keep the sheep bed clean and dry. 6 Planting high-quality pastures to provide nutritious and well-tolerated high-quality forage grasses is the key to the high-quality and highly-efficient breeding of goats. Farmers can choose according to their own circumstances, such as the autumn pasture varieties of winter animal husbandry -70 rye, ryegrass, etc., can be mixed at the same time a small number of legume forage. Sowing methods should be used for sowing or sowing, winter grazing - 70 rye can be used mechanical sowing, ryegrass seed is small, generally artificial sowing. Spring sow grass species such as Pennisetum or Sudan grass. Seeding methods can be used live or nursery transplanting, and seedling transplanting is better than live, nursery in late March to early April, transplanting in early May. Practice shows that planting 1 mu of pasture can meet the demand of 8 to 10 sheep. 7 Lamb fattening The purpose of fattening lambs is to increase daily weight gain and feed utilization. Feed minerals and concentrates on the premise of ensuring sufficient green feed or hay. Farmers can purchase goat mineral bricks and hung them in a circle for sheep to feed freely. Concentrates can be prepared using corn, soybean cake and other raw materials. A feed formula is recommended here for reference: corn 55%, wheat bran 25%, rice bran 4%, rapeseed cake 8% and bean cake 8%. 8 Appropriate body suitable for slaughter goat meat slaughter is based on comprehensive evaluations such as daily gain, feed utilization, slaughter rate and other performance indicators and market demand. The slaughter weight was too low, the goat's growth potential was not fully utilized, and the amount of meat produced was also low. The slaughter weight was too high. Although the amount of meat produced increased, the feed utilization rate decreased. The peak period of hybrid sheep growth was later than that of local sheep, and its appropriate slaughter weight should be larger than that of local sheep. 9 Regular immunizations should be carried out regularly in and out of the sheep-raising houses and regularly disinfected with bleaching powder and 100-total poison. In the spring and autumn seasons, the animals were repelled with broad-spectrum anthelmintic drugs such as disometamin, levodozole, and trichlorfon, and three pairs of seedlings or five pairs of seedlings and goat pox were selected according to the epidemic situation of the local herd. , Vaccine against inactivated foot-and-mouth disease, and infectious pleuropneumoniae vaccine are regularly or irregularly vaccinated.
