Studies on the relationships between trace elements and some blood components and fertility in Egyptian buffaloes

ABSTRACT

The present investigation carried out on a total number of 50 buffalo- cows, 25 repeat breeder and 25 with smooth inactive ovaries. Fifteen normal fertile buffalos were used as control. The mean values of serum copper, zinc, iron calcium, inorganic phosphorus, magnesium and total protein in normal fertile and infertile buffalos were tabulated. The obtained results showed a highly significant decrease in both serum copper and inorganic phosphorus in buffalos with ovarian inactivity as well as in repeat-breeder buffalo-cows
