Abstract :

Reproductive disorders, one of the important factors causing economic loss in the bovines (cattle and buffaloes) of organized dairy farms. In the present study relationship of reproductive disorders with mineral and hormone status in bovines of organized dairy farms was done. Paired sera samples (128, 195, 109 and 138) at one month interval were collected from bovines of organized farms in Dharwad, Bijapur in Karnataka and Pondicherry, Chennai in Tamilnadu. Serum was screened for Brucella and Infectious bovine rhinotracheitis (IBR) antibodies and analyzed for mineral and hormone profiles. The reproductive problems observed were 49 (8.5%), 167 (29.3%), 16 (2.8%) and 7 (1.2%) of abortion, repeat breeding, metritis and anoestrus respectively. Out of 570, 254 (44.6%) and 158 (27.7%) were positive for Brucella and IBR antibodies respectively. Serum copper, zinc, calcium, magnesium, phosphorus were 1.35 ppm, 1.40 ppm, 9.01 mg%, 1.64 mg%, 3.42 mg% and 1.24 ppm, 1.02 ppm, 9.70 mg%, 1.65 mg%, 3.09 mg% in apparently healthy and reproductive problem bovines respectively. The serum zinc and phosphorus levels showed significant decrease in animals with reproductive problems. Serum estradiol and progesterone concentration were 3.50 pg/ml, 2.94 IU/ml and 2.18 pg/ml, 2.46 IU/ml in apparently healthy and reproductive problem animals respectively. Significant decrease in levels of estradiol and progesterone concentrations in bovines with reproductive disorders was observed. There was association between reproductive disorders with minerals and hormone status in bovines of organized dairy farms. Thus, minerals and hormone status evaluation may aid in early detection of bovines with reproductive disorders.
