First, excellent varieties. The Swiss Saint Bernard is selected as the father and the local dog is the female parent for crossbreeding. After the comparison test, there are five advantages compared to the local dog breed: one is a weight gain of 25%; the second is a high birth rate, with 8 to 12 litters per litter, 2 litters per year, an increase of 20%, and 3 low feed consumption, a decrease of 15 %; Fourth, there are many incomes, which is 100-150 yuan more than the local dogs. The fifth is fast-food slaughter, and the fattening after weaning reaches 30 kg to 35 kg in 4 months. Second, the appropriate kennel. Take a squat pile limit breeding method. The kennels are kept warm in winter and cool in summer. Each occupies an area of ​​1.4 square meters, and a squat pile is placed 1.5 meters apart. The height of the columns is 60 centimeters. Each of the kennels has a pile and the columns are arranged in double rows. The bottom of the ditch is 18 centimeters wide and 12 to 13 centimeters deep. The sides of the ditch are plastered with cement and are inclined at 30 degrees. The dog collar is made of nylon rope and the reins are 2 meters long. A movable food device is also provided for easy cleaning, and 1 set for each dog. Third, a reasonable feed mix. Take fed compound feed plus anesthetic. The formula for diets is: corn 30%, soybean meal 10%, wheat bran 10%, turtle powder 7%, bone meal 2%, salt 1%. Another 0.03% added Datura, mixed in the feed. Get up to sleep and reduce howling. Fourth, scientific feeding methods. The dog's feed must be cooked. The steamed bean head accounts for 60% of the diet and the remaining 40% is porridge. Adhere to the "three set": First, regular, fed 4 times a day, starting from 7:00; the second is quantitative, fed 0.4 kg to 0.5 kg a day; 3 is a fixed water, sufficient water, winter drinking warm water (15 ~ 25 °C ) Let the dogs drink freely. V. Strict prevention and control of disease and disease. To achieve "two early": First, disease-free early treatment. Daily excrement of urine, regular disinfection in the spring and summer, do not feed rotten spoilage feed, insist on not fattening fattening, playing "five joint vaccine" (rabies, parvovirus, hepatitis, canine distemper, dog paraflu), in dog fattening 60 The following days of injection 3 times, 90 days of injection 2 times; Second, early treatment of disease. In addition to rabies, common diseases of meat dogs need to be repelled. Once a quarter, levamisole is used at a dose of 10 mg per kilogram of body weight. If the dog is found to have delirium, use realgar 10 grams, sulfur 70 grams, 100 milliliters of soybean oil, boil, rub the affected area. The dog's dynamics are often observed, with particular attention to enteritis, once treatment is found.
