Abstract
Twenty one growing Salady lambs with an average live body weight of 25.8 kg and about 6 months old were used to study the effect of partial substitution of corn grains by dried sugar beet pulp on their growth performance. Dried beet pulp was integrated into tambs' rations at levels of 50% and 75% of com grains on OM basis. Lambs received one of the following experimental diets: 1) concentrate mixture 1 (CM 1) + berseem hay (BH). 2) CM 2 + BH. and 3) CM 3'" SH. Concentrate mixture was red at 60% of OM required while 8H ad. Lib in all treatments. Three digestibility trials using three lambs of each group were carried out to determine nutrients digestibility and nutritive values of the experimental rations. Data obtained showed that dried sugar beel pulp (DSSP) was higher in CF coruent tnan corn grains (19.88 vs. 4.59%) and ash content (4.16 vs. 1.95%). While NFE and CP content of corn grains were higher than that of DSBP (79.36 and 9.51 vs. 64.43 and 9.37% respectively). Apart from CP and EE digeslibililies. the highest nutrients digestibIlity was recorded with lambs red ration 2 followed by those fed rations 1 and 3. Crude protein digestibility of ration 1 was the highest compared by those of rations 2 and 3. However, the differences among rations were not Significant (P>0.05). The TON ot ration 3 was SIgnificantly (P<0.05) lower than ration 2. There is no significant difference among experimental ration regarding OCP%. OMI by lambs fed control ration was similar to those fed ration 2 (1120 vs. 1127 gJ day respectively), While It was slightly higher than that intake by lambs fed ration 3 (1120 vs. 1087 g/day). Average daily gain was 153.57, 160.71 and 164.23 gJ day for lambs fed rations 1,2 and 3, respectively. The results showed that integration of DSBP into lambs' rations at 50 or 75% of corn grain improved feed conversion expressed as kg OM, TON or OCP per kg gain. Feeding costs were 4.92, 4.49 and 4.15 LEI kg gain for lambs fed rations 1. 2 and 3, respectively.
From the data obtaIned here it can be concluded that dried sugar beet pulp can be used as a good source of energy for growing lambs. It can be also used successfully as a substitution of corn grains at replacement rates of 50 or 75% of com grains dry mailer
