The present study was planned to determine serum micro-mineral status (copper, iron, zinc, selenium) in cyclic and anoestrus buffaloes during March to June, 2008. Serum micro-mineral contents were determined by atomic absorption spectrophotometer. Mean serum concentrations of copper, iron, zinc and selenium in cyclic buffaloes were 70.59 µg/dl, 370 µg/dl, 181.4 µg/dl and 0.10 µg/ml, respectly. The corresponding values for anoestrus animals were 62.23 µg/dl, 358.13 µg/dl, 164.07 µg/dl and 0.07 µg/ml. Compared with cyclic buffaloes, there were significantly lower serum copper, iron, zinc and selenium levels in anoestrus buffaloes (P<0.05). It was concluded that deficiencies of copper, iron, zinc and selenium either singly or in combination, could be responsible for anoestrus condition in Nili-Ravi buffaloes. Thus, by improving the nutritional status, fertility can be improved in buffaloes.
