[Serum amylase activity in calves, lambs, goats, rabbits and chicks]

Investigated was the serum amylase activity in calves at different age, in lambs, goats, rabbits, and birds. Some species variations were established in the amylase activity, it being highest in rabbits, followed by birds, cattle, goats, and sheep. In calves after drinking colostrum the amylase activity dropped, rapidly assuming the same values as in adult cattle. It was found that in cows with chronic arthritis, endometritis, and mastitis as well as in cases of subacute cases of pneumonia in calves, as compared to normal animals, the serum amylase activity was lower.
