The relationships between nutrition and udder inflammation/infection were studied in the dairy cow using an ecopathological approach. The study ('enquête écopathologique Bretagne') was performed over 4 yr in French herds with high-lactating cows. A long distribution time of Italian ryegrass silage and a low quantity of dietary cereal-based concentrates in the first 2 months of lactation was linked with low milk leukocyte counts, probably due to a high dietary energetic level or to a polyunsaturated fatty acid imbalance and a subsequent decrease in the synthesis of leukotriene LTB4. In the late gestation period, a long distribution time of fresh English rye-grass, which induced high uraemia and a larger distribution of vitamins A, D and E, was related to lower frequencies of major pathogens in the milk.
采用生态病理学方法研究了奶牛营养与乳房炎症/感染之间的关系。这项名为“布列塔尼生态病理学调查”的研究在法国高产奶牛群中进行了4年。在泌乳的前两个月，意大利黑麦草青贮饲料的长期供应时间和低量的谷物类浓缩日粮与低乳白细胞计数有关，这可能是由于高日粮能量水平或多不饱和脂肪酸失衡以及随后白三烯LTB4合成减少所致。在妊娠后期，新鲜英国黑麦草的长期供应时间导致高尿素血症以及维生素A、D和E的分布增加，这与牛奶中主要病原体的较低发生率有关。
