| Abstract | ||||
| Twenty-four Ossimi male lambs (initial BW 22 kg) were used to study the effect of increasing level of screening whole cottonseed (SWCS) on performance, digestibility, rumen fermentation and intake of OM, CP, NDF, ADF, hemicellulose, cellulose, lignin and ether extract. Animals were fed four diets containing either 0, 8, 16 or 24% SWCS. The SWCS replaced corn and soybean meal to maintain calculated TON and CP concentration at 65 and 14%, respectively. Animals were given ad libitum access to feed and water. Results indicated that DMI, ADG decreased (P>O.05) lineary with increasing SWCS level. Diet containing 8% SWCS level had showen better feed efficiency (gain/feed) compared to those either contained 16 or 24 % SWCS levels or nil WCS (control). However, the difference was not statistically significant. Apparent digestibility coefficients of OM, OM, and CP decreased with increasing SWCS level, but without significant effect. Diets containing 16 and 24% SWCS level had higher (P>O.05) increase EE digestibility. While higher (P>O.05) increase in NDF, ADF, ADL, hemicellulose and cellulose digestibility were observed with 16% SWCS level. Diets containing 0 and 16% level of SWCS showed more NI, NO and NR. Calculated MP synthesis was not affected by SWCS level. It was concluded that incorporation up to 24% SWCS level in the diets was accepted; however, 16% SWCS level could be suggested as a safety level for local lamb diets. | ||||
