Abstract: | Digestibility and feeding trials for 10 and 90 days were conducted using 25 yearling Farta rams with a mean body weight (BW)
of 16.8 ± 0.17 kg (mean ± SD) to study the effects of supplementation with sole or mixtures of noug seed meal (NSM) and wheat
bran (WB) on feed intake, digestibility and BW change in Farta sheep fed hay. The experimental design was a randomized complete
block design. The sheep were arranged in five blocks based on initial BW, and the five treatments were assigned randomly to
each animal in a block. The five treatments comprised of ad libitum hay (control, T1) and ad libitum hay plus daily supplementation of 300 g dry matter (DM) sole WB (T2), 2WB:1NSM (T3), 1WB:2NSM (T4) and sole NSM (T5). Supplementation
increased total DM (P < 0.01) and crude protein (CP) (P < 0.001) intake and promoted daily BW gain (P < 0.001). Non- supplemented
sheep consumed more (P < 0.01) hay DM compared to the supplemented treatments, except T2. Among supplemented sheep, T5 had
higher (P < 0.001) CP intake than the other treatments. Supplementation improved (P < 0.001) the digestibility of CP. Lack
of statistical differences in daily BW gain between the different supplements used in this study suggests that sheep producers
can use the different feed supplements considered in this study depending on their availability in the order of T4, T5, T3
and T2, respectively. |
