ABSTRACT

To assessed the reproductive problems and their association with reproductive failure in dairy Cattle two questionnaires were designed for this study, the first one for individual cows with infertility problem (207cow) and second one for the randomly selected farms (93farms), in Khartoum North (Bahri North and East Nile localities), Khartoum State, Sudan. The study revealed that the major reproductive Problems were repeat breeding 132(63.8%), retained placenta 47(22.7%), reproductive infection which includes (pyometra, metritis, viginitis and anoestrus) 18(8.7%) and abortion 10(4.8%). The risk factors such as breed, age, parity and mating system, were assessed and their associations with reproductive problems were evaluated in this study. There was association between age of cows and repeat breeding problem, increase in cows’ age followed by increase in the repeat breeding problem, there was association between the presence of Mineral block (any source of mineral and vitamins) in farms and cows with repeat breeding problem, the repeat breeding was higher in the farms that not using any source of minerals and vitamins. There was association between origin of cows and the reproductive infection, the reproductive infection in cows purchased from other farms was higher than in cows that born in the farm, and the relative risk of reproductive infection in cows purchased from other farms to be with reproductive infection was almost two time to that for cows born in farm.
