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: First, inbreeding, physical deterioration; Second, do not pay attention to deworming, consume a lot of nutrition; Third, there is no scientific ingredients, can not meet the nutritional needs of sheep growth and development. In order to make mutton grow fast, we must master the following technologies: 1. Select species sheep There are no meat sheep species in China. Only the introduction of large-scale foreign breeds with good meat-producing performance, domestic good breeds and local native-breed sheep adopt artificial insemination. Method to obtain a hybrid product mutton 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. Two more practical feed formulas are described below for scientific ingredients: (1) 45% corn flour, 20% rice bran, 10% soybean cake, 15% cottonseed cake, 12% Maifu, 30% soybean cake, 1% salt, 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.

Streptococcus is a genus of LAB, which is gram-positive and globe-shaped, classical strain is Streptococcus Thermophilus, which is broadly used in the yogurt starter culture.
Streptococcus thermophilus strain primarily use in DVS yogurt starter culture, and package from 200u-1000u, relatively to make 1 ton to 5 ton yogurt.
