奶山羊实验性过食黄豆的血液学研究

20只装置永久性瘤胃瘘管的假定健康奶山羊进行了过食黄豆对其血液理化性质影响的研究。结果表明,一次给予40、00、80g/kgwt黄豆,分别可导致发病,明显临床症状和死亡;过食黄豆是一个由酸中毒转入以氨中毒为主的代谢性碱中毒的全过程,血氨浓度与黄豆的给予量呈正相关;血液pH值先下降(7.13±0.22,P<0.01)而后上升(7.86±0.25,P<0.01),血浆CO_2CP先降低(12.03±2.73mmol/L,P<0.05)而后升高(22.76±0.76mmol/L,P<0.01),血乳酸先升高(2.07±0.22,P<0.01)后降低(1.23±0.05mmol/L,P<0.01);血氨、血pH值及血浆CO_2CP的升高,是过食黄豆在血液理化性质方面的特征。

STUDY ON THE HEMATOLOGY OF EXPERIMENTAL SOYBEAN ENGORGEMENT IN DAIRY GOATS

Twenty supposed healthy dairy goats with permanent fistulae were used in a study on the influence of soybeam engorgement upon the physiological and biochemical properties of blood, the results are as follows: Animals given at a time 40g/kgwt of soybean were ill, those given 60g/kgwt were seriously ill those given 80g/kgwt died. Soybean engorgement was a process, starting with acidosis and followed by matabo-lic alkalosis with the ammonia playing the chief role in the latter. There was a positive corrlation between the ammonia concentration in the blood and the amount of soybean given. The pH value in the blood decreased first ( 7.13 0.22, p<0.01 ) but increased later ( 7.86 0.25, p< 0.01), blood plasma CO2CP droped first ( 12.03 2.73mmol/L, p<0.05 ) and rose later ( 22.76 0.76mmol/L, p<0.01 ) , the concentration of lactic acid in blood rose first ( 2.07 0.22mmol/L, p<0.01 ) and droped later ( 1.23 0.05mmol/L, p<0.01). The increase of the blood ammonia,the blood pH value, and the blood plasma CO2CP were the features of the physiology and biochemistry under soybean engorgement.
