Abstract

The present study was conducted to evaluate silage quality, concentration of
pesticides residues, degradability and feeding value of silage containing cotton stalks
(CS) and 1‘t cut of berseem (B) treated with or without inoculants of lactic acid
bacteria, (LAB) and supplemented with or without dried yeast (DY). The silages were:
1- (CS + B) silage; 2- (CS + B) silage plus BY; 3- (CS + B) silage treated with LAB
and 4- (CS + B) silage treated with LAB plus DY.
Silage treated with LAB leads to good quality silage. Concentration of
pesticides residue in all silages were less than the limits of quantification (0.05 mg!
kg).
Diet containing silage treated with LAB and supplemented with DY had
higher (P: 0.05) nutrients digestibility coefficients, feeding values, nitrogen utilization,
effective degradability (96) of DM and OM. So, silage treated with LAB and
supplemented with DY could be recommended for ruminants feeding during summer
season.
