| Abstract: | In order to obtain the basic information of the environmental situation for beef cattle production in Yili area,the environmental indices detected from a typical collective beef cattle farm were evaluated.CO2,NH3 and CH4,luminosity,temperature,humidity and noise,PM10 and TSP of the beef cattle cowshed were measured for consecutive 10 days in the spring.The results showed that in the spring,the daylight time was about 10 h from 08:00 to 18:00,and the average value of luminosity,temperature,humidity and noise were 105.61 Lux,16.30 ℃,49.56% and 64.59 dB,respectively;The average value of CH4,CO2 and NH3 concentrations were 0.09,880.91 and 0.51 mg/m3,respectively;The average value of PM10 and TSP concentrations were 0.030 and 0.010 mg/m3,respectively.By zooming in the day and hour fluctuation of above measured environmental indices it was found that the average temperature in this cowshed was over the maximum limit of national standard from 11:00 to 24:00 lasting for about 13 hours.It was concluded that the general environment in this area was suitable for beef cattle production except the temperature in this cowshed needs to be improved for providing better welfare for beef cattle. |
