Bovine cysticercosis considered to be a dangerous problem for both public health and the livestock economy. The present study aimed to determine the cysticercus bovis prevalence and their economic losses in slaughtered cattle in Menofia governorate. Visual meat inspection of 2640 cattle carcasses at different abattoirs of Menofia governorate was carried out allover one year extended from January 2015 to December 2015. The results revealed that, the prevalence of cysticercus bovis in slaughtered cattle was 6.09% and the affected organs were head (masseter and tongue), heart and whole carcass with infection rates of 3.63%, 2.42% and 0.04% respectively. Moreover, the morphological description and measurements of recovered cysticercus bovis were recorded. It was observed that, the cysticercosis cause sever economic losses, as the estimated annual financial losses of cysticercosis in slaughtered cattle was 87032 Egyptian Pound (EGP).
The objective of this study was to assess the reproductive performance and disorders of pure Holstein-Friesian (HO) and Montbeliarde (MO) crossbred cows in a commercial dairy herd under Egyptian conditions. Analysis was done for age at first calving (AFC), number of services per conception (NSPC), days open (DOPN), gestation period (GP), and calving interval (CI). The results revealed that the AFC, NSPC, DOPN, and CI of crossbred cows (MO×HO) were significantly lower than those of pure HO cows. GP was numerically shorter in HO cows than in MO × HO crossbred cows. In both breeds, the NSPC was significantly lower in the winter than it was in the summer. During the summer season, pure HO cows had the longest DOPN. However, the shortest DOPN was recorded in MO × HO crossbred cows in the winter season. A significant difference between calving seasons was found with regard to the calving interval. MO × HO crossbred cows had a higher percentage of affected cows with retained placenta, endometritis, and repeat breeding than pure HO breeds. It was concluded that MO×HO crossbred cows had higher fertility than pure HO cows. Additionally, MO×HO crossbred cows were minimally affected during different seasons under Egyptian conditions. However, pure HO cows likely performed better than MO×HO crossbred cows in terms of reproductive disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
