The second is to build a house with double-film mulch, and pile up and position the material. The double-film covered kennel has good thermal insulation in winter, and the temperature is suitable, which can be adjusted according to the temperature and humidity required for the growth and development of meat dogs, thus avoiding the phenomenon that the temperature changes greatly in spring and autumn in traditional high-density captivity and meat dogs are prone to diseases. Compared with the conventional pen house, the double-film pen house can increase the slaughter rate of meat dogs by 15%, the growth rate and feed utilization rate by 7.5% ~ 19.0%, more commercial dogs are slaughtered every year, and the income is increased by 20% ~ 35%. The kennel should be built in a place far away from residential areas, with high and dry terrain and sunny lee. The high terrain is conducive to keeping the house dry and hygienic; Sunlight can make full use of solar energy for heating. The kennel should face south, 30-50 meters long and 4.5 meters wide, and a 3-meter-wide cover should be made at the back and upper part of the pen house. The eaves height before the cover is 1.8 ~ 2.2m, and the eaves height after the cover is1.5 ~1.9m.. In front of the kennel1.5m, two layers of arch supports (steel pipes and bamboo pieces) are installed, and the support spacing is 20 cm. There are three rows of east-west wedge-shaped piles in the shed, with the row spacing of 1.2 ~ 1.5m and the pile spacing of 0.6 ~ 0.8m Each meat dog is tied to the piles with a chain of 0.4 ~ 0.55m long. Pay attention to the free rotation of the bolted joint to avoid accidental casualties of meat dogs.
Thirdly, the meat dogs were fed with different proportions of feed to prepare anesthetic pellet feed. According to the growth and development law of meat dogs, the low-energy and high-protein feed formula was adopted in the early stage of growth, and the high-energy and low-protein feed formula was adopted in the later stage, so as to improve the nutritional level required by meat dogs at different growth stages, promote the rapid development of meat dogs, save feed costs and improve economic benefits. The reference values are as follows: the total feed energy of meat dogs should be 15 ~ 16 MJ/kg, the crude protein content in the early stage is 2 1% ~ 23%, and in the later stage it is 16% ~ 19%. The feed is mixed with narcotic drugs (Datura, weeds, Buddleja, etc.). ) and made into pellet feed. After eating anesthetic feed, meat dogs reduce energy consumption and are conducive to growth.
Fourth, comprehensively prevent diseases. Large-scale breeding of meat dogs requires comprehensive prevention in houses, utensils and dogs. Pens should be kept clean, feces should be removed at any time, and disinfected thoroughly every 7 days; The disinfectant is 10% ~ 20% bleaching powder solution or 0.3% ~ 0.5% peracetic acid solution. Dogs should always clean their utensils and pots, and dogs should be vaccinated regularly. Measles vaccine was injected at the age of 4 weeks, each dog was injected with 1ml, five vaccines were injected at the age of 8-9 weeks, and five vaccines were injected at the age of 12 weeks, and the drugs were used to repel insects every 50 days. The dosage of levamisole or albendazole is 65438 05 mg per kg body weight. Timely isolation and treatment of sick dogs.
