An experiment was conducted with male broiler chicks to study the effects of 20 and 23% of crude protein (CP) combined with 0, 50, 100, 150, 200, 250 mEq/kg of dietary electrolytic balance (DEB) on the pancreatic a-amylase activity from 1 to 21 days. A completely randomized factorial design was used. Feed and water were supplied ad libitum. At days 1, 7, 14 and 21, three birds from each treatment were sacrificed by cervical dislocation, pancreas were removed, homogeneized and […]

The effects of two levels of L-glutamic acid (L-Glu) combined with four levels of vitamin K (Vit K) were studied with the objective of evaluating the activities of a-amylase in the chyme and pancreas of chicks. Day-old male broilers were reared in eletrically heated batteries, fed with purified amino acids diets, minerals and vitamins (except Vit K) at the requirement levels, for 14 days. Feed and water were provided ad libitum. The experimental design was a factorial 2×4 with four […]
