Forty-eight heifers of two genotypes, Boran (Bos indicus) and Holstein×Boran, were allocated to three feeding levels equivalent to 1.0, 1.2 and 1.4 times calculated metabolisable energy requirements for maintenance (MEm). The experiment started at the onset of reproductive activity, when the Bora...

This study examined the effect of lablab hay supplementation of crossbred cows fed forages from cereal+forage legume intercropping (maize–lablab (ML) stover or oats–vetch (OV) hay) basal diets on feed intake, apparent digestibility, milk yield and milk composition of crossbred cows. Forty eight m...

Thirty-six crossbred cows were used in a 2 X 2 factorial arrangement in a randomized block design to evaluate forages from two cropping systems (1 and 2) and feeding levels (ad libitum, (Level1)) or 80 percent of ad libitum (Level 2) on milk yield, live weight, and reproductive performance. Crops...

Efficient input supply and service delivery may call for a hub approach where all the necessary inputs and services are supplied in a coordinated manner, either by a single supplier or by several and separate entities in a given geographical location accessible to beneficiaries. Based on experien...

Data on reproductive performance of Zebu and Friesian X Zebu crossbred cows reared under small-scale dairy farms were analysed and the effects of genotype, parity, body condition score (BCS), season, and year of calving were examined for a total of 246 calvings. Uterine involution was completed e...

Gonadal and extragonadal sperm reserves were determined in testicular and epididymal tissues obtained from 14 small highland Abyssinian Zebu (SHAZ) and from 15 Borana bulls slaughtered at the Debre Zeit abattoir. Bulls were mature and over six years of age. Body weight and scrotal circumference w...
