摘要
本研究对安达地区散养户和养殖小区不同季节原料乳的乳成分、微生物指标及抗生素残留检出率进行检测,结果表明不同季节和不同养殖方式对原料乳的乳成分、微生物指标及抗生素残留检出率有显著影响。具体表现为:冬季原料乳成分显著高于其他季节,夏季原料乳的细菌总数等微生物指标明显高于其他季节;养殖小区原料乳的理化指标高于散养户,细菌总数等微生物指标和抗生素残留检出率均低于散养户。
In this paper, milk composition and microbiological changes of raw milk were detected in different seasons from backyard farmers and farming communities in Anda area, and the data was statistically analysed using SPSS 17.0 software. The results showed that the different seasons and different farming methods had a significant effect on milk composition and microorganisms of raw milk. Specifically as follows： raw milk composition in winter was significantly higher than that in other 3 seasons, the total number of bacteria and other microbial indicators of raw milk in summer was significantly higher than that in other 3 seasons, physicochemical indexes of raw milk from farming communities was higher than that of raw milk from backyard farmers, and the total number of bacteria and other microbial indicators and antibiotic residues detection rate were lower than those in raw milk from backyard farmers.
