Olive Oil Cake as Animal Feed C. Use of Olive Oil Cake Supplemented with Soybean Seeds in the Rations of Growing Barbary Lambs

Abstract

Olive Oil Cake (OOC) was used to replace part of the commercial concentrate (14% CP) of Barbary lambs on a dry matter basis al the rates: commercial concentrate without OOC (control). 15%, 25% and 40%. Supplemental soybean seeds were added to make the rations isonitrogenous at 16% CP. Each ration was fed to one group of lambs for the entire experimental period and oat hay was fed as roughage. Lambs performance and ration digestibility were determined.

Differences in daily weight gain between groups were not significant except that the group fed the highest OOC level showed a significantly lower rate of gain when compared with the control group. The digestibility of CP and CF of the ration that contained the highest level of OOC was reduced.

It is concluded that the high fat and fiber contents of rations for growing lambs depressed digestibility and therefore growth rate. However. OOC successfully replaced 25% of the commercial concentrate for growing lambs, when it was supplemented with soybean seeds.
