The study was conducted to evaluate the reproduction efficiency of zebu and crossbred cows measured by the inter-estrus and inter-service intervals using data from Bako Agricultural Research Center. The overall mean inter-estrus and inter-service intervals were 44.3 t 0.85 and 49.1 t 1.24 days, r...

Boran is an endangered breed of cattle indigenous to Ethiopia and the relatively poor understanding of its reproductive physiology has impeded efforts to maximize reproductive performance of the breed. This study characterized ovarian follicular dynamics in 9 purebred Boran and 8 Boran×Holstein (...

Traditionally, most smallholder farmers in Goma and elsewhere in Ethiopia engage in sheep and
goat fattening to generate sufficient income to meet household requirements and other social
obligations. A rapid assessment with IPMS project partners in Goma found that traditional sheep
fattening is c...

Insufficient feed supply is a major limiting factor for milk production in the tropics. The
aim of this study was to assess the effects of feeding level on live-weight and performance
of Zebu (Boran) and crossbred (Boran

This study was conducted at Ginchi watershed in Oromia Regional State, Ethiopia to evaluate the
physical, chemical and microbiological quality of livestock drinking waters during dry, short rain and wet
seasons. Purposive sampling technique was used to obtain samples. Data were collected and anal...

Twenty-seven Boran and 37 Boran x Friesian bulls, weaned at six months of age, were allocated to either receive supplementary diet (16 percent crude protein and 10.8 MJ/kg DM energy) during the dry season or to serve as unsupplemented controls until 21 months of age. Body weight measurements were...
