1. Selecting breed sheep There are no meat sheep breeds in China. Only by introducing the inbreeding method of foreign breeds with large size, good meat production performance and domestic good breeds and local native breed sheep, we obtain hybrid sheep. For example: Boer goats cross with local goats. Hybrid sheep exhibit strong heterosis, fast growth, strong disease resistance, and high feed conversion rate. 2. Repelling parasites should be dewormed prior to sheep fattening. With the highly effective anthelmintic levamisole, 8 mg per kilogram of body weight is dissolved in warm water, and a 5% aqueous solution is formulated for intramuscular injection, which can drive out various roundworms and nematodes in the goat; use sulfur bis(dichlorophenol) per Kg body weight 80 mg, add a little flour 250 ml of water, empty gavage, can drive off the sheep liver schistosomiasis and aphids; after shearing with 1% -2% trichlorfon liquid medicine bath to eliminate ectoparasites. This avoids additional nutrient losses to the sheep and ensures fattening. 3, scientific ingredients are now two more practical feed formulations are introduced as follows: (1) 45% of corn flour, rice bran 20%, 10% of soybean cake, cottonseed cake 15%, Ma Fu 12%, 30% of bean cake, salt 1%, The percentage of fish crushed is 150g per day after weaning. With the increase of age, the daily feed can be increased to 200g, 400g at 6 months old and 500g at 7-8 months old. The above two formulas may be optional. The sheep fattening is based on green hay, sweet potato meal and corn stalk, etc. The batch materials are only fed as supplementary feed. 4. Feed additives commonly used additives are the following: (1) sheep fat fertilizer compound feed additives. It consists of trace elements, rumen metabolism regulators, and growth promoters. Applicable to the year of sheep and the elimination of rams, old and weak adult sheep fattening. The grazing sheep supplemented the concentrates and the mixture was fattened for 90 days. The average daily weight gain was 137 grams, which can significantly improve the fattening effect and economic efficiency, shorten the fattening period, and save feed. (2) Monensin sodium, also known as rumen. The role is to control and increase the efficiency of rumen fermentation, thereby increasing the rate of weight gain and feed conversion. The dosage is 25-30 mg per kg of diet. (3) Olaquindox, also known as fasting spirit, is a synthetic antibacterial agent. Promotes protein assimilation by adding 50 mg per kg of diet. (4) Urea. Its purpose is to supplement the lack of protein in the feed and feed it in the concentrate at 1.5%-2%. The number of sheep fed each day is 0.02% of the body weight of the sheep, that is, the daily amount of adult ewes is 10-15 grams, 6-8 grams of young sheep aged over 6 months, and the amount of first feeding can only be fed by 1/10 of the prescribed amount. gradually increase. It can be added to the prescribed amount after 10 days. To prevent urea poisoning, urea should not be fed alone, nor should it be dissolved in water. Do not drink water within half an hour after feeding. For diseased sheep and weak sheep with little or no feeding, in case a poisoned sheep is found, it can be rescued by filling it with 0.5% vinegar 200-500 ml or 1-2 kg yogurt. 5. Epidemic Prevention and Control The common diseases of mutton sheep production include: Lamb dysentery, symptoms of loss of appetite, diarrhea, fecal odor, lying in the ground. Prevention: 0.15-0.2 g of oxytetracycline was fed 12 hours after the birth of the sheep, and furazolidone was used as the diseased lamb and 0.01 grams per kilogram of body weight was taken orally. Enterotoxemia manifested as rapid watery diarrhea, lying on the floor, difficulty breathing, white vomiting, and head throwback. During the prevention and control period, regular injections of sheep epidemic disease, enterotoxic blood, and other triple vaccines were performed. The diseased goats were intramuscularly injected with penicillin at a dose of 80-1.2 million units. In addition, rumen hernia, pneumonia, etc. should also strengthen prevention and treatment.
The medicinal use of Astragalus membranaceus has a history of more than 2000 years. It has the functions of enhancing immune function, protecting liver, diuresis, anti-aging, anti-stress, antihypertensive and a wide range of antimicrobial activities. However, it is forbidden to use the evidence of excessive superficial pathogenic factors, stagnation of qi stagnation and dampness, stagnation of food accumulation, excessive heat and toxicity at the beginning of carbuncle or after ulcer, and excessive Yin deficiency and yang.
Fast fattening technology of Boer goats
The goats raised in rural areas weighed only 15 kg at the age of 12 months, and the sheep of the native species had a body weight of about 25 kg at the age of 12 months. The reasons for the slow growth rate are as follows: First, inbreeding, physical deterioration; second, no emphasis on deworming and consumption of large amounts of nutrients; and third, no scientific ingredients are used to meet the nutritional needs of sheep growth and development. To make mutton sheep grow fast, you must master the following technologies:
