| Popis: | A cross-sectional survey, an assessment of recorded data and measurements of different traits were conducted to determine the reproductive and early growth performances of Horro cattle and their F1 Jersey crosses of the study area. The mean(SD) total farmland, cropland and grazing land holdings of individual smallholder householders were 3.6±3.16, 2.86±2.51 and 0.81±0.89 respectively, while the mean(SD) livestock species holding were 17±11.66, 2.9±3.98,2.9 ±4.83, 1.8±1.66 and 9.3±8.97 for cattle, sheep, goats, equine and poultry respectively. Anestrous, repeat breeder, endo-metritis and dystocia were the main reproductive health problems which were found to occurs with the proportion of 21.1%, 19.7%, 5.6% and 1.4%, while the remaining 52% attribute to non pregnancy in cows due to voluntary waiting period, postpartum period and lack of AI service. The overall mean age at first service across both production sites(on station and on farm) was 48.85 months for local Horro and 33.25 months for Horro-Jersey F1 Crosses, where as the mean (SD) NSPC for Horro and Horro-Jersey crossbred heifers was found 2.1±1.09 and 1.7±0.94 respectively. Breed of animals had high significance effect at (P < 0.001) on AFS and AFC. The mean birth weight of Horro and Horro-Jersey crossbred calves was 17.5±2.25 and 18.2±2.03 kg respectively. Calf birth weight was significantly (P |
