The objective of the study was to determine the influence of glutamine (GLN) and BCCA (leucine, isoleucine and valine) on hematological, biochemical and immunological parameters of post-weaning canines. In the first stage of the study, the food to be administered as a basis during the experiment was analyzed, determining that this and other foods analyzed met the nutritional requirements of the puppies. Thus, this food served to feed 31 mix puppies from four litters of 20-25 days of age, randomly in each litter a control group was established (without supplement) and 3 treatments supplemented with amino acids on the base food: T1 (GLN 0.5 g/kg/day/PO), T2 (BCCAs, 0.25 g/kg/day/PO) and T3 (GLN 0.5 g/kg+BCCA 0.25 g/kg/day/PO), were kept for 90 days in a controlled environment under equal conditions, individually fed twice a day, samples were taken at 30, 100 and 120 days of age. At 30 days, the means and ranges of the hematological and biochemical parameters were similar. At 120 days, differences were determined in the hematological parameters (p0.05), however, the average number of leukocytes (10.33 10*9/ L) and the average number of neutrophils (7.17 10*9/L) of treatment two were higher than the average of the control group and of the treatments one and tree. Blood biochemistry parameters did not show differences (p>0.05). The levels of total immunoglobulins G, M, A, at 30 days of age presented levels lower than the ranges reported for canines without showing significant differences (p>0.05) between the treatments under study at 100 and 120 days of age, as well as the concentrations of specific immunoglobulins for canine distemper (IgGDC, IgMDC), however, the animals supplemented with BCCA showed the highest averages of immunoglobulins after supplementation. IgE showed decreasing levels from 30 to 120 days of age, showing a good level of adaptation of the animals to food and supplements. In conclusion, supplementation with glutamine and BCCA at the doses used in this study were not significantly influential in a greater activity of the immune system in the weaning stage, but supplementation with BCCA seems to favor certain cell groups and function. immunity of canines at this stage.
