Abstract

Both salinomycin and virginiamycin as feed additives in
ruminants diet were nutritionally evaluated through digestibility
and feeding trials. Eighteen growing Ossimi lambs, averaging 11.6
± 0.31 kg in live body weight were assigned on three diets. The
diets were (D1) control, (D2) control + 12 ppm salinomycin, and
(D3) control + 36 ppm virginiamycin. The control ration consisted
of 75% concentrate feed mixture (CFM) + 25% rice straw (RS).
Significant differences (P <0.05) for the final body weight gain
between control diet (D1) and other two diets were recorded.
Insignificant differences were observed between the control diet
(D1) and the other two diets containing salinomycin (D2) or
virginiamycin (D3) in total dry matter intake (TDMI) or average
dry matter intake, g/day (ADMI, g / day), while the digested crude
protein (DCP) values recorded for D2 and D3 were significantly
higher (P < 0.05) then those for D1. Insignificant differences were
observed in OM, CF, NFE and EE digestibility coefficients
between treatments, but the crude protein digestibility (CPD),
values were significantly different (P <0.05) for D2 and D3
compared to the D1. Insignificant differences for TDN and SV were
recorded. Concerning the economical evaluation, D2 or D3 were
very similar and recorded clear advantage comparing to the D1.
