Email this article Effect of Management and Supplementation on Reproductive Performance of Hammari Ewes under Range Conditions in North Kordofan State, Sudan
Abstract
The study was conducted in ElNuhoud locality, West Kordofan State with the objective of studying the effects of pattern of husbandry and Supplementation with concentrate on Desert ewes’ fertility, lambs birth weight and their growth rates. The study used 80 Hammari Desert ewes that were randomly divided into four equal groups (each with 20 ewes) weighing . The first group (A) was left to graze on natural pasture from 6 pm to 7: am, stayed under shade from 8: am to 5: pm and watered once every 3 days. The second group (B) was managed as treatment A but watered daily. The third group (C) was kept on natural grazing from 6: pm to 7: am, stayed under shade from 8: am to 5: pm, drank daily and offered concentrates at the rate of 0.5 – 1.0 kg/ewe/day. The ewes in the fourth treatment group (D) was left on the natural grazing from 6-a m to 12:00 (mid-day), stayed under shade for three hours, allowed to graze till midnight and watered once every five days representing control. The results showed that all treatments improved the performance of ewes and lambs with the best performance for group that was offered concentrate supplement (group C). The supplementation of lambs after weaning did not improve their growth rate, so it was concluded that supplementation of lambs is not needed, when the pasture is plentiful and of good quality.
