Abstract: The purpose of this study was to understand the spring changes of the environment of intensive mutton sheep sheds in Xinjiang and the correlation between the environmental changes and lamb health.Environmental indices including the illumination,temperature,humidity,noise,concentrations of CO2,NH3,CH4,PM10 and TSP were measured consecutively for 15 days in two typical sheep farms which were located in Wensu county (WS) in Southern Xinjiang and Mulei county (ML) in Northern Xinjiang.24 h changes of the above indices were measured in 5 consecutive days,then which were compared between the two sheep farms.At the same time,the clinical observation of lamb health and disease was carried out in two sheep farms.The results showed that the average noise in ML sheep farm was extremely higher than that in WS (P<0.01).The average concentration of NH3,CO2,TSP and PM10 in WS sheep farm was extremely higher than that in ML (P<0.01);24 h change of the above parameters showed that the temperature in the two farms about 15,24 h in one day was over the limit of NY/T 388-1999,respectively.The main diseases of lambs in the spring were diarrhea,pneumonia and paralysis,and the cough rate of the lambs in WS was higher than that in ML (P<0.05).The paralytic rate of lambs in ML farm was higher than that in WS (P<0.05).In conclusion,the environmental indices in two sheep farms were not exceeded to the limit of NY/T 388-1999 except the temperature.The results showed that the environment of two sheep farms in spring was more suitable for the growth and development of sheep.However,the temperature of the sheep house needed to be controlled to ensure the welfare and health of the animals.The lambs in two sheep farms were in good health in spring,but it was necessary to strengthen the feeding management of newborn and weak lambs in colostrums and supplementary feeding of fattening lambs in ML sheep farm.This study laid a certain foundation for the environment standard of meat sheep farm in Xinjiang,which also provided a scientific basis for the feeding management,animal health and welfare and the improvement of production level for Xinjiang sheep farms.
