| Abstract |
The solid-slale fermentation (SSF) technique was applied on peanut hulls (PNH) and sugar cane bagasse (SCB) with T. viride fungal to improve their nutritive value as feedstuffs for ruminants. Contents of OM and CF were decreased after treatment, while contents of CP. EE and ash increased after treatment than those of untrealed one. Total nitrogen (TN) and non-protein nitrogen (NPN) were increased after treatment for both PNH and SCB than before treatment. while true protein nitrogen (TPN) was decreased with fungal treatment of crop residue than untreated one. Insoluble protein in sodium (lSP) chloride was decreased after fungal treatment of PNH. while increased with treated SCB than untreated one. Insoluble and soluble protein in pepsin after treatment of SCB was higher than that PNH.
Four digestion trials were conducted to determine nutrients digestibility and nutritive value of tested rations. The 1st and 2nd groups received untreated peanut hulls and sugar cane bagasse, while 3rd and the 4th groups received treated peanut hulls and sugar cane bagasse. respectively.
Fungal treatment reduced feed intake of peanut hulls and sugar cane bagasse than before treatment by 43.20 and 35.30%. respectively. The digestibilities of CP, CF and EE were significantly (P<0.0I) increased with rations containing untreated SCB than PNH, while NFE was lower significantly (P<0.01). On the other hand, the digestibilities of CP and gross energy were reduced significantly (P<0.0 I) with feed treated SCB than treated PNH. The value of DCP % was decreased significantly (P<0.01) with feeding treated SCB than PNH. while the nutritive ratio of treated SCB was increased. Treated peanut hulls and sugar cane bagasse lowered nitrogen balance than untreated rations. Feeding either treated peanut hulls or sugar cane bagasse increased significantly (P<0.01) pH values and concentration of NH3-N in the rumen liquor compared with untreated rations.
Blood serum TP and glucose were comparable for treated and untreated PNH, while the lowest values were recorded for group fed treated SCB. Globulin concentration in blood serum was significantly (P<0.01) increased with untreated compared with treated SCB, while the corresponding values did not differ between treated or untreated PNH.
Urea nitrogen in blood serum was higher (P<0.01) with treated PNH, while no significant difference was found between treated or untreated SCB. The price of TDN unit was higher by 7 1.43 and 90% for treated PNH and SCB respectively.
In conclusion. using the SSF technique as a microbial treatment for SCB or PNH was not proven economic. The research work in this area may need more studies to obtain reliable results
