Abstract: The objectives of this study were to explore the effect of different dietary NFC/NDF ratios on ruminal and blood endotoxin and histamine concentrations,3 Guanzhong dairy goats with permanent ruminal cannulae were divided into 4 groups and each time lasted for 10 d according to self-contrast design experiment. The goats were fed diets with different NFC/NDF ratios,which the ratios were 1.02(Ⅰ group),1.24(Ⅱ group),1.63(Ⅲ group)and 2.58(Ⅳ group),respectively. The results showed that with dietary NFC/NDF ratios increased,ruminal endotoxin and histamine increased. Resulting in blood endotoxin and histamine increasing. When NFC/NDF ratio was 2.58,concentrations of histamine and endoxin in blood and rumen increased significantly with the development of SARA,indicating that increased release of histamine and endotoxin in blood and rumen played an important role in the development of SARA.

Key words: NFC/NDF ratio; endotoxin; histamine; subacute ruminal acidosis
