Supplementations of Maintenance Level Concentrate on Productive and Reproductive Performance of Local Arsi Dairy Cows On Farm in West Arsi Zone, Ethiopia
Journal Title: Global Journal of Animal Scientific Research - Year 2015, Vol 3, Issue 1
Abstract
On farm feeding trial was conducted in wanchitu and dibayu site within Gambeltu PA of west Arsi zone of Oromiya region, using 16 dairy cows possessed by the local farmers of second parity to demonstrate the effect of supplementing concentrate at the rate of 2kg/day/cow on the productive and reproductive performance local dairy cows. Data collected was analysed using GLM procedure of SAS. Data on heart girth, body length wither height, reproductive efficiency and body weight was collected. The result of body weight derived from the heart girth indicated and confirmed by weighing scale indicated that there was no significance difference in initial and final weight of both supplemented and un supplemented cow. But there is a significant difference in change in body weight with the un supplemented group showing weight loss at the rate (-0.152095 kg/day) and the supplemented group showing weight gain at (0.016190 kg/day). More over the supplemented group showed 62.5% more efficiency in reproduction in terms of coming to heat than the unsupplemented cows. Supplementation of dry local cow in dry season resulted in year round reproduction. In turn increases the rate at which on farm F1 production through Artificial insemination.
