| Abstract | ||
| The present research work was carried out at Maryout Research Station where sugar beet tops were available at EI-Bostan (EI.Nobariah area). The objective of this study was to indude the relatively available feed resources in the area such as sugar beet tops (hay or silage with 5% of molasses) to replace berseem hay in the fattening diets of lambs. I Twenty·seven 5-month-old male Bart<l lambs weighing 24.67 ! 2.12 kg were used. Animals were divided into three equal groups and were assigned at random to receive one of three dietary treatments. The control group (T1) was offered tHe traditional fallening diet composed of concentrate feed mixture (CFM) to covrr maintenance requirements. clover hay (CH) ad lib. Sun dried sugar beet lops hay replaced berseem hay In diet Z (TZ). while sugar beet tops silage with 5% molass~s replaced berseem hay in diet 3 (T3).The experiment lasted for 75 days. Their intake and growth were recorded biweekly. Three animals from each treatment were slaughtered at the end of the experiment for carcass evaluation. During the experimental period. the animals were able to Consume twice and triple their maintenances requirements for TDN and DCP, respectively. Results revealed that the averages of daily gains were 172. 144 and 170g or lambs fed rations in treatments T1, T2 and T3, respectively. Corresponding values for the economical efficiency for lambs were 3.57. 4.11 and 4.70, respectively. Feeding lambs on sugar beet tops as (hay or silage) caused an appreciable reduction in feeding cost for producing one kg body weight. The average cressmq percentages based on fasting body weight were 41.~6, 44.71 and 45.62 for lambs in n, T2 and T3. respectively. while the boneless meal percentages were 60.60, 62.33 and 58.64. On the basis of the results of this experiment. it could be recommended that farmers and Bedouins in Maryout and EI· Nobureih regions could use the hay or silage of sugar beet tops as a rough~ge Instead of berseem hay for feeding their lambs since they are palatable and of good feeding value and more profitable for lambs. | ||
