Abstract


The role of Phosphorus, Copper, Zinc, Manganese and Cobalt in reproductive function was evaluated on the basis of serum values of these elements in fertile, anoestrous and repeat breeder cows. Serum samples drawn from 17 cows each of the above 3 groups were used for estimation of inorganic phosphate, Copper, Zinc, Manganese and Cobalt. The levels of serum .inorganic phosphorus was 7.526 + 0.5304 mg % in fertile cows, 6.082 + 0.3337 mg % in anoestrous cows and 6.345 ± 0.4474 mg% in repeat breeder cows. The level was significantly lower (P<0.05) in anoestrous cows. The serum copper in fertile cows was of 0.73+0.0511 ppm which was significantly higher than in anoestrous (0.509 ± 0.0591 ppm) and repeat breeder cows (0.542 ± 0.0415 ppm). The serum Zinc,manganese and Cobalt in fertile, cows were 1.337 ± 0.1555 ppm, 0.0553 0.0095 ppm and 0.0702 ~ 0.0100 ppm respectively. The corresponding values for anoestrous cows were 1.028 ± 0.0984; 0.0339 ± 0.0052 ppm turd 0.0641 0.0052 ppm and in repeat breeder cows 1.017 + 0.0654 ppm, 0.0429 0.0033 ppm and 0.0795 ± 0.0111 ppm. There was no significant differcnce in these values between groups.
