金黄色葡萄球菌诱导型乳腺炎对中国荷斯坦奶牛乳中脂肪酸组成的影响
Effects of Staphylococcus aureus-Induced Mastitis on Milk Fatty Acid Composition of Chinese Holstein Cows
摘要
Abstract
The aim of this study was to explore the effects of Staphylococcus aureus ( S.aureus)-induced mas-titis on milk fatty acid composition and their absolute content of Chinese Holstein cows.The bacterial suspen-sion of S.aureus was administered into the udder to establish a S.aureus-induced mastitis model in experimen-tal group, and PBS was administered in control group.Fatty acid absolute contents in milk were determined by gas chromatography.The results showed as follows:thirty four fatty acids were detected in milk, and fatty acid synthesis at breast area was directly affected by S.aureus-induction.The fatty acids were divided into six cate-gories by degree of saturation and carbon chain length, and compared with 24 h before infection, the absolute contents of short chain fatty acids ( sc-FA) , medium chain fatty acid ( mc-FA) and saturated fatty acid ( SFA) at 11 h after infection in experimental group were significantly lower ( P<0.05); control group had the same changing tendency, but there were no significant differences ( P>0.05) except sc-FA.At 23 h after infection, the absolute content of all six categories of fatty acids in experimental group lower than those in control group. The results indicate that the dynamics of fatty acids had the same trend.These results demonstrated that S.au-reus-induced mastitis can affect the synthesis of cow fatty acids and lowered the absolute content of each com-ponent.关键词
