| Abstract | ||||
| Twelve crossbred Friesian cows were used in double 6 × 6 Latin square design, each period lasting 28 days. They were fed according to their body weight (550±10.50 kg in average) and previous milk yield (10 – 12 kg/day average) on tomato haulms in fresh form (FTH), hay (HTH), hay treated with fungus, (Trichoderma reesei, HTH+F) or tomato haulm silage (STH) or tomato haulm silage with bacteria (Sill-All®) (STH+B) or tomato haulm silage with dried yeast (STH+B+Y) in addition to concentrate feed mixture (CFM). While three other females sheep fitted with permanent rumen fistula were used for rumen fermentation and in situ studies. Sheep were offered silage adlibitum plus 750 (g/head/d) CFM for fermentation trials, while cows were fed 8 kg / head / day of CFM in addition to dry yeast (DY) ( 5 g / head for sheep and 10 g / head for cow) with feeding TH silage with bacteria. Animals fed treated TH with fungi or silage without bacteria had higher NH3-N concentration, while those fed on STH+B or STH+B+Y had higher TVFA's. Higher MP was recorded with HTH+F or STH+B+Y. Soluble, insoluble fraction and DE of DM, OM, and CP were higher for animals fed HTH+F or STH+B+Y. All of these were reflected on the more milk and 4% FCM yield, while concentrations of residue of pesticides were dramatically decreased. Picture of blood showed an increase in glucose, cholesterol. Globulin, urea, creatinin, AST and ALT with untreated TH, while all these parameters decreased following fungus treatment or ensilage TH with bacteria and DY. Based on that, it is recommended to treat TH with fungi or incited it especially with B+DY. Were more effective in animal performance. | ||||
