Resumo: |
This research aimed to evaluate the influence of Vitamin E administered by intramuscular injection (IM), on hematological, biochemical, physiological and electrocardiographic parameters of young goats at the dry period (DP), and at the rainy period (RP), in semiarid of Paraiba. For this were used, for each period, 12 crossbred males, at the age of 60 ± 12 days, and mean weight of 12 ± 2,5 kg, which were distributed into two groups (n=6), called Control Group (CG) and Treatment Group (TG).Animals of the CG had not received any kind of treatment, while the others of the TG received vitamin E (20mg/kg IW), once a week, during 112 days. During this time and for each period was realized in gaps of 14 days (M0, M1, M2,M3, M4, M5, M6, M7 and M8) blood cells analysis, biochemical dosages and evaluation of physiological and electrocardiographic parameters. The obtained data were compared by the t-test (p<0.05), and by the non-parametric Mann-Whitney test (p<0.05). At DP, for CG and TG, the statistical significance was demonstrate at 42 (M3), 98 (M7) and 56 days (M4) for red blood cells variables, with higher means for the no treated animals. There was no significant difference for the means related to white blood cells analysis. At RP it was observed that the Corpuscular Hemoglobin Mean Concentration (MCHC), at 28 days (M2), was statistically significant with the means of TG higher than the CG, while the count of Monocytes at 42 days (M3) and of Segmented Neutrophils at 56 days (M4) was significantly higher for CG. For biochemical parameters, at DP, there was not observed significant statistical variations. At RP, for CG and TG, the statistical significance was observed at 98 days (M7) for Globulins and Albumin:Globulin ratio, and at 28 days (M2) for Creatinine. At DP, for CG and TG, there was no significant difference for Body Temperature (BT) and Cardiac Frequency (CF), however at 28 days (M2) was observed statistical significance for Respiratory Frequency (RF), at 14 days (M1) for QRSms complex and at 84 days (M6) for RmV wave. At RP, for CG and TG, no statistical significance was verified for physiological parameters, however was showed significant difference for Pms wave at 70 (M5) and 98 days (M7) and for PRms gap at 84 days (M6). It was concluded that the doses, the way and the frequency ofadministration of vitamin E, purposed in this research, promote a increase for erythrocytes values, at DP; vitamin E suggests turn better the phagocytosis function of Neutrophils at RP; it exercises no influence on serum biochemistry at DP, however is efficient to maintain the normal concentration of Globulins and Albumin:Globulin ratio at RP; it can be used in young goats to improve the immunologic answers; it exercises no influence on physiological parameters, being these influenced by the environmental temperatures; vitamin E does not present effects on cardiac electrophysiology of young goats in semiarid. |
