The aim of this study was to evaluate the effect of spray dry blood plasma (SDBP) supplementation for newborn piglets on performance, seric biochemical variables, total antioxidant levels, and nitric oxide. Thus, 20 newborn piglets, with lower body wheith (1.179 ± 0.276 kg) were distributed in an experimental design with five randomized blocks (females were considered block), with two treatments and ten repetitions. The treatment consisted to provide 10 g of SDBP (group T), previously diluted at 1:4 (blood plasma/water) administered for the first hour post-birth of the piglets, and a control group (group C; without blood plasma administration). The performance of newborn piglets was evaluated at days 1, 8, 15, 22, and 28 after birth, and the seric biochemical variables (cholesterol, triglycerides, gamma-glutamyl transferase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and urea), total antioxidant levels by ferric reducing ability of plasma (FRAP) method, and nitrite/nitrate (NOx) levels were evaluated at days 5, 15, and 22 post-birth of the piglets. No difference was observed in treatments (groups C and T) for weight gain, as well as for the most biochemical variables, except GGT and NOx (P < 0.05). There was a significant effect (P < 0.05) on age for ALT, AST, and FRAP, i.e., these variables increase in serum. Triglyceride levels have a tendency for reduction (P = 0.07) according to the age. GGT activity and NOx levels were lower (P < 0.05) in group T, as well as the AST levels that showed a tendency for reduction in this group compared to group C. Therefore, supplementation with 10 g for SDBP did not interfere in the weight gain, but altered the GGT activity and NOx levels in the serum of newborn piglets with low weight.KeywordsPerformanceSeric biochemicalFRAPGGTNOx
