Abstract Background Multifetal births are the most significant economic characteristic in goats. Therefore, physiologically, exploring influence of their birth frequency on genital function and milk production is vital. The present study was carried out to monitor potential effect number type udder, yield, composition, ovarian follicles, certain blood parameters dam's Baladi goats during postpartum period. On day, fifty goat dams were separated into five equal groups based births: (G1)...

Background and Aim: Foot-and-mouth disease (FMD) is an extremely contagious viral that affects domestic wild cloven-hoofed animals. In Egypt, FMD has been enzootic since the 1950s caused great economic losses in cattle buffalos over past few years. This study aimed to detect virus (FMDV) serum raw milk samples collected from infected adjacent different localities El Menofia Governorate, Egypt. Materials Methods: Blood were apparently diseased 100 cows buffalos. Serum prepared used for...
