Study On The Hygienic Quality Of Beef Cattle’s Feeds In Main Fattening Farms In Xinjiang

The aim of the study is to get a preliminary understanding of the hygienic qualitysituation of beef cattle’s feeds in Xinjiang. The coliform, salmonella, total mould and nitritecontent were detected in feeds collected from six beef cattle fattening farms located in theprefectures of Yili and Akesu according to national standard detection methods. Results wereas follows: The range of coliform was30/100g to11000/100g in all detected feeds, amongthem the highest was3440/100g in straw feed, the lowers were less than40/100g in bran,cotexpeller, rapeseed dregs, premix feed. The range of mould was10~920000/g,and silagehas the lowest groups of mould that is less than700/g. Suspicious colonies were not detectedin the preliminary separated cultivation of salmonella; nitrite was detected in some feeds, yetits content was less than20mg/kg. This study preliminarily shows that nitrite contents arelow in feeds for beef cattle in main fattening farms in Xinjiang, and there is no microbialcontamination or other serious pollutions take place. This study offers a foundation for thehygienic evaluation in the process of production of beef cattle feed in Xinjiang.
