With the objective of assessing the development of organs of the digestive tract and the enzymatic profile α-amylase, lipase and trypsin, an experiment lasting 21 days was carried out using one-day-old male Avian Farm broiler chicks, reared in heated batteries and fed ad libitum with water and purified diets containing all L-essential amino acids, glutamic acid (nonspecific nitrogen source), minerals and vitamins. A randomized complete design was used with four replications of ten birds. At one, seven, 14 e 21 […]
