Abstract
Twenty-seven Barki lambs, averaged 24.66kg body weight and aged 6 months were used to study the effect of feeding sugar beet tops on their growth performance, digestibilities, carcass characteristics and some blood constituents. Animals were divided equally into three groups, each of nine lambs and each animal was provided with a concentrate mixture at level of 40% of its nutritional requirements. In addition, the three groups were randomly allotted to be fed ad lib. on one of three experimental rations, berseem hay (ration A); sugar beet tops silage (ration B) and dried sugar beet tops (ration C).
The results obtained revealed that digestibilities of all nutrients were significantly (P<0.05) higher for ration (B) than those for rations (A) and (C) except the digestibilities of dry matter and crude protein which did not differ significantly between rations (B) and (A). Also the nutritive values of rations (A) and (B) were significantly (p>0.05) higher than those of ration (C). Voluntary intake (as TDN or DCP) from the experimental rations were significantly higher for rations (A) and (B) than from ration (C). These results were reflected on the body weights of animals, where lambs fed rations (A) and (B) gained more weights than those fed ration (C). Consequently, feed efficiency of these rations improved in the same trend. Feeding growing lambs on dried or ensiled sugar beet tops resulted in palpable decreasing in feeding cost for producing one kg body weight. Nitrogen intake, digested and retained N by lambs fed rations (A) and (B) were significantly all higher than those of ration (C). Carcass characteristics of lambs were not affected by feeding dried or ensiled sugar beet tops. On the other hand, feeding growing lambs on ration containing dried sugar beet tops (ration B) resulted in a significant increases in serum total protein, albumin, globulin and creatinin in comparison with those of lambs fed on rations (A) and (C).
Results of this study countenance using dried or ensiled sugar beet tops for feeding growing lambs.
