EFFECT OF ORGANIC ZINC SUPPLEMENTATION ON SOME BIOCHEMICAL AND HEMATOLOGICAL PARAMETERS OF LOCAL GOATS DURING PREGNANCY AND LACTATION
Abstract
The objective of this study was to investigate the effect of organic Zinc (Zn) supplementation on some biochemical parameters of local goats in late pregnancy and lactation stage. The experiment was undertaken at a private goat's field in Akre district/ Dohuk governorate. A total of 24 pregnant local goats at week 6 of pregnancy were allocated by parity into 3 treatments (groups) for Zinc supplement (0.35 and 70 mg Zn) during (4) periods (0, 15, 30 day and after parturition). The results showed that the treatment (35 mg Zn) surpassed significantly (p<0.05) the other treatments for glucose, Alanine Aminotransferase (ALT), Lymphocyte Percentage (LYM% ), Red Blood Cell Count (RBC) and Packed Cell Volume (PCV) values. However, the period (After-Parturition) significantly affected (p<0.01) urea, AST, WBC and RBC surpassing the other physiological stages. Most correlation coefficients between the studied parameters were significant (p<0.01). The highest positive coefficient was between RBC and PCV (0.871), while the highest negative coefficient was between RBC and MCV (-0.378). In conclusion, the Zinc treatment revealed that its importance in different periods is to maximize some parameters for improving the physiological status of goats.
