Abstract

The effect of Nigella sativa cake (NSC) (capsules after oil
extraction) on growth performance of Ossimi lambs, nutritive values
and feed conversion were studied in a feeding trial. The NSC was
included at 0, 12.5, 25 and 37.5% of the tested diets replacing
concentrate feed mixture (CFM) formulating four dietary treatments.
The control diet consisted of 75% CFM + 25% sugar cane bagasse
(SCB). Twenty four growing ossimi male lambs of 21 ± 1 kg live
body weight were distributed into four similar groups. Each group < br />was fed one of the four different dietary treatments in feeding period
which lasted 90 days.
Results of digestibility revealed that NSC improved
significantly (P≤0.05) organic matter (OM), crude protein (CP), crude
fiber (CF) and nitrogen free extract (NFE). Nutritive values followed
the same pattern. While, lambs daily gain, feed consumption and feed
conversion were not significantly affected. Economical evaluation
was in favor of NSC diets especially at 37.5% level.
