Human exchange networks are instrumental in influencing gene flow among domesticates. Here, we investigated levels of within- and between-population genetic diversity in 289 animals from six indigenous sheep populations in Egypt (Barki, Farafra, Ossimi, Rahmani, Saidi, Souhagi) and 119 individual...
Presents a summary and comparison of the demographic and production characteristics of five livestock production units studied by ILCA from 1978 to 1984. Discusses herd structure, calving rates, calf mortality, cow mortality, calf growth, milk production and herd productivity.
Reports studies on the reproductive performance and its associated problems in indigenous cattle at the Ministry of Agriculture farms in central Ethiopia, at Abernossa and Gobe ranches which are cattle breeding centres of the Ministry of Agriculture. Presents constraints of reproductive performan...
Determines the reproductive performance and problems in indigenous cattle at the Ghibe valley farming populations in central Ethiopia. Discusses the constraints of reproductive performance in cattle, such as genital infections, nutrition, traditional management, prenatal losses like embryonic mor...
Examines milk production during early, middle and late phases of lactation in indigenous (Bos indicus) Arsi and Zebu cattle and their crosses with Jersey and Friesians. Analyses milk yield, lactation persistency and milk secretion coefficients.
Reviews the reproductive performance of African indigenous sheep and goats in different agro-ecological zones and under various management systems. Presents and discusses data on age at first parturition, litter size, the interval between successive parturitions annual reproductive rate, length ...
Goats and sheep are versatile domesticates that have been integrated into diverse environments and production systems. Natural and artificial selection have shaped the variation in the two species, but natural selection has played the major role among indigenous flocks. To investigate signals of ...
