Vitamin and mineral supplementation improves erythrocytic recovery and productive performance of infected by gastrointestinal parasites

ABSTRACT The objective of the present study was to evaluate the effect of a vitamin and mineral complex, associated with the application of an efficient anthelmintic, in parasitized lambs, with characteristic signs of gastrointestinal nematode infection, on hematological clinical parameters of clinical improvementand weight gain. 60 lambs Australian Merino breed, with 8 and 9 months of age, were segregated in four groups: control (no supplemetation); formula 1 (Iron Dextran, Organic Phosphorus, Cyanocobalamin and Vitamin k); formula 2 (Iron Dextran, Organic Phosphorus and Cyanocobalamin); and formula 3 (Vitamin k). Hematocrit, prothrombin time, total plasma proteins, color of the conjunctiva and weight gain were analyzed. The results were submitted to analysis of variance (ANOVA) through the repeated measures test. There was no statistical difference between treatments for the variables of hematocrit (P = 0.564), prothrombin time (P = 0.911) and plasma proteins (P = 0.6), for the conjunctiva color variable there was a difference (P = 0.052 ), with greater results for the groups supplemented with Vitamin K, Butafosfan, Cyanocobalamin and Iron (groups F1 and F3), as well as those same groups reached higher body weight at D35 (P = 0.023). It can be concluded that the administration of vitamin and mineral complex, associated with efficient anthelmintic, promoted a better performance in parasitized lambs.
