Effect of Feeding Non-Conventional Energy on Productive Performance of Rahmani Lambs.

Abstract

This study was conducted to assay the using of non-conventional energy sources on chemical composition, digestibility coefficients, cell wall constituents, nutritive value and productive performance of growing Rahmani lambs. Twelve Rahmani lambs with average body weight 22.60±0.20 kg and 4 months old were used in this study for 120 days. Lambs were distributed into two similar groups (6 lambs each) and randomly assigned to two experimental rations. The two respective rations composed of R 1 (control) contained 60% concentrate feed mixture (CFM)+40% rice straws(RS). While, R 2 consisted of 55% CFM + 40% RS + 5% corn steep liquor (CSL).The digestibility and nutritive values of experimental rations were determined using six adult Rahmani rams. Rumen liquor and blood samples were collected at the end of collection period. The results showed that nutrient digestibility and feeding values were higher (P<0.05) for rations R 2. The highest values of TDN and DCP were observed R 2. Digestibility of cell wall constituents (NDF, ADF, cellulose and hemicellulose) were improved by treatment. Blood constituents were generally normal in all experimental groups. Growth performance e.g. total body weight gain and average daily gain was improved in R 2. The same trend was observed for feed conversion and economic efficiency and the best values were recoded with R 2. It could be concluded that addition of CSL to ration of growing Rahmani lambs could improve their productive performance and economic feed efficiency.

Effect of Moringaoleiferalam Leaves Supplementation on Rumen Fermentation, Digestibility, Free Radicals and Productive Performance of Growing Lambs

“…This positive achievement in FCR by R3and R2 could be attributed to the significant effect of incorporation of dried Moringa leaves in rations fed to animals of those groups on their rumen activities, nutrients digestibility and growth performance. Mahmoud (2013) reported that rations contained Moringa oleifera stems achieved higher feed efficiency than control rations with highly significant different and concluded that Moringa oleifera stems are suitable for feeding sheep and can be used to replace a part of clover hay or concentrate feed mixture without any adverse effect on the performance of Rahmani lambs. Worku (2016) reported that Moringa leaves totally replacing cottonseed cake in growing lambs fed on low-quality hay increased hay intake, diet DM digestibility and daily weight gain.…”

“…However, stalks as the main by-product for moringa crop has not utilized in animal feeding although it represents 30% of plant (Dechasa et al, 2006). Few studies have been conducted on utilization of moringa stalks in fattening lambs (Mahmoud, 2013).…”
