The aim of the present study was to evaluate blood copper (Cu), zinc (Zn), Iron (Fe) and Manganese (Mn) status of healthy goats (209) managed under semi intensive system in the three different agro-climatic zones of Punjab. For this purpose, two hundred nine blood and hair samples of various breeds of goats were taken. The samples were analyzed for trace minerals by using atomic absorption spectrophotometer (AAS) and the prevalence was recorded. Plasma Cu, Zn and Mn concentrations were significantly (P≤0.05) different among the three zones. The mean plasma Cu (0.57 ± 0.65 mg/l) concentration was lowest in sub-mountainous zone, whereas Zn (1.73 ± 0.12 mg/l) and Fe (4.83 ± 0.31mg/l) were lowest in central zone and Mn (0.81 ± 0.07 mg/l) was lowest in south-western zone. Hair concentration of Mn was significantly (P≤0.05) different among the zones, but Cu, Zn and Fe had non-significant differences. Subclinical deficiency of copper (73%) was the most prevalent trace mineral deficiency in goats followed by zinc and iron deficiencies. From the present study, it was clear that lower production and poor performance of goats in Punjab may be attributed to the trace mineral deficiency. Hence, regular supplementation of trace minerals is highly recommended.
