Guangxi Yulin is located in South China, and the high-quality Sanhuang chicken breeding industry is developed, with an annual output of 2.5 billion. According to the growth characteristics of high quality yellow chicken, the temperature in the chicken chick stage (21d) should be maintained at 32~35Â°C and the humidity is 70%~80%. The average annual temperature in Yulin is as high as 20~25Â°C, but the average temperature in January is It is 13 Â° C and the lowest temperature is below 10 Â° C. In the winter and spring seasons, in addition to the addition of two stoves per house, farmers generally do not take effective measures to prevent cold and warming. Farmers pay insufficient attention to the insulation of chicks, resulting in low survival rate of chickens. The production performance of many broiler breeding companies in winter and spring is quite different from that in autumn. The greater the difference in broiler age, the more difficult it is for settlers to settle and the cost increases. According to statistics, the increased breeding cost of breeding companies from January to May each year exceeds 2 yuan / feather. In the Yulin area, asbestos and chicken houses are generally used, and insulation facilities such as thermal insulation frames or plastic films are installed in the house. These measures can ensure short-term temperature is not difficult, but it is difficult to ensure suitable temperature and humidity during the whole breeding process of the chicks. It is not uncommon to burn down whole chickens and chicken houses due to improper insulation. Magnesite insulation material is a cement-based composite material with foam and foam. It has a unique hardening mechanism, good adhesion, heat insulation and good mechanical strength. Qian continued, Song Tianming. The effect of insulated chicken houses on the performance of laying hens. Livestock and poultry breeding, 2010 (5): 50-51. (Continued from page 103) (CK), treatment 2, treatment 3 The average incidence of pigs in different breeding models were 23.33%, 23.33%, 10%, respectively. The difference between treatment 1 (CK) and treatment 2 was not significant, and the difference between treatment 1 (CK), treatment 2 and treatment 3 was extremely significant, indicating that the economic high-bed micro-ecological fermentation bed breeding model can effectively reduce the incidence of pigs. Comparing the economic benefits of the three different farming modes, the difference between the processing 3 and the processing 1 and the processing 2 was significant, indicating that the economical high-bed micro-ecological fermentation bed culture is better than the traditional cement floor and traditional fermentation bed. Comparing the construction cost, breeding benefit and breeding environment results, the economical high-bed micro-ecological fermentation bed pig raising method can not only solve the shortcomings of cement ground pigs and traditional fermentation bed pigs, but also achieve the effect of ecological pig raising. Develop a low-carbon, zero-emission, sustainable development model.
