Abstract: Design of light steel structure modular mutton sheep breeding, fattening, summer as early as 6 average temperature 1.3 ℃ higher than the same period the environment temperature and humidity is 9.5% higher than the same period the environment; The afternoon 14 when the average temperature of 1.6 ℃ lower than the environment; Humidity is 8.3% higher than the environment,with the total strain of corn silage total mixed diet(TMR) fattening Luxi black mutton sheep, average daily gain amounting to more than 237 g to test three groups diet formula best practical and economical effect. Winter under the condition of the conventional heat preservation measures,the cage average temperature 5.29 ℃, 0.73 ℃ higher than the average temperature of outside environment and inner minimum temperature of 7.83 ℃, 1.42 ℃ higher than that of outer environment lowest temperature, cage drinking water. Use medium nutrition level grain fattening Luxi black mutton sheep, test period, the average daily gain of 272 g, material weight ratio of 6.60:1, after deducting feed all income only 104.27 yuan, economic benefit is obvious. Test results show that combined light steel structure(fattening) bred cage not only less investment, simple structure, convenient disassembly, assembly good ventilation, the air quality in the cage is superior to the state of NY/T388《livestock and poultry field environment quality standard》, but also convenient for drinking water, feed, clean sanitation, suitable for agricultural mode of production of mutton sheep fattening small and large groups, for no or less of farmland development high quality mutton sheep production, has the reference significance.
