EFFECT OF REARING TYPE ON PHYSIOLOGICAL RESPONSE OF LOCAL GOATS IN THE SULAYMANIYAH REGION

Abstract

This study was conducted in two different areas in the Sulaymaniyah Governorate / Kurdistan Region of Iraq, in spring 2021. Thirty-six adult local goats (18 does + 18 bucks) and different colors of goats (black, brown and white), aged 1.5-2 years by using two types of rearing, OG: Open grazing (for this system Qaiwan area was used, Mountainous logic), the animal in the group open grazing deepening on natural grazing for all days. IS: Intensive system (for this system Arbat area was used, not a mountain logic), the animal in the group intensive system depending on traditional feeding regime. The purpose of this study was to see how different husbandries affected some blood and hormone parameters. Moreover, blackbuck goat’s, (WBCs), L%, MCHC, and MCV were significant differences (p<0.05) for OG, and MO%, N%, N/L, Hb and HCT for IS, brown goat’s, L% and MO% for OG, and (WBCs), N/L and MCHC for IS, white goat’s, (WBCs), L%, Hb and HCT for IS and MCHC for OG. Black doe goat’s, N%, E%, B%, N/L, RBC, Hb, and MCV were significant differences (p<0.05) for OG, and (WBCs), L%, MO%, MCHC and MCH for IS, brown goat’s, N%, E%, N/L and MCV for OG, and L%, RBC, MCHC and MCH for IS, white goat’s, (WBCs), L%, N%, Hb and MCHC for OG and N/L and RBC for IS, whereas other parameters were not significant. Cholesterol level in both sexes of (black and white) and brown doe goats were significant differences (p<0.05) for IS, brown buck goats was not significant. The total protein level in both sexes of black goats and brown doe goats were significantly different (p<0.05) for IS, while brown buck and white doe for OG. Glucose concentration was significantly different (p<0.05) in both sexes of three-color in OG, except brown doe, was for IS. Cortisol levels, in both sexes, were significant differences (p<0.05), (black and white buck) and (brown and white doe) goats for IS, whereas brown buck and white doe for OG. Adrenocorticotropic (ACTH) levels in buck goats were not significant, while white and brown doe were significant differences (p<0.05) for OG, black doe for IS.
