“…Fermentation broke down the fibrous structures of the cowpea seed hulls cellulose, cellobiose and β glucose. Willis et al (1980) reported that some physical or chemical modification may be beneficial for improved utilization of residues with high lignin and cellulose contents. Thus, the grinding and partial digestion may improve utilization of the hulls by poultry.…”

Feeding has been reported to be responsible for the high cost observed in poultry production. The use of unconventional feedstuff for poultry production is however limited due to their fibrousness and inability of birds to possess the cellulase enzyme that can digest the fibre, nevertheless, physical treatments of these unconventional feedstuffs enhance their possibility in poultry production. The objective of this study therefore, was to evaluate the nutrient status of cowpea seed hull after being subjected to different treatment. The Cowpea seed hull that was not subjected to any form of treatment served as the control i.e. Untreated cowpea seed hull (UCH), while a portion was soaked and boiled (soaked and boiled cowpea seed hull, SBCH) and another portion soaked for 3 days, soaked cowpea seed hull (SCH). The seed hull in each treatment were analysed for their proximate composition, metabolisable energy (ME) and fibre fraction. The trial revealed a steady increase in crude protein (CP) of the test materials with the highest increase (18.43%) in crude protein recorded in SCH substrate compared to 6.73% increase in SBCH substrate. A corresponding decrease in crude fibre (CF) was recorded with 15.00% loss for SCH substrate while 6.97% loss in crude fibre was observed for SBCH substrate. Changes of 1.73% and 4.22% were recorded for nitrogen free extract (NFE) in SBCH and SCH respectively, while ME changes by 1.67% and 5.39% for SBCH and SCH substrates respectively. The effects of both physical treatments on ash and insoluble ash were not significant. Fibre analysis revealed that 7.55% (53.00% to 49.00%) and 18.87% (53.00% to 43.00%) of acid detergent fibre (ADF), 7.41% (81.00% to 75.00%) and 16.05% (81.00% to 68.00%) of neutral detergent fibre (NDF) and 2.5% (40.00% to 39.00%) and 22.5% (40.00% to 31.00%) of cellulose were loss in SBCH and SCH substrates respectively. There were no significant effects on the acid detergent lignin (ADL) and hemicellulose components of the test samples due to these physical treatments. The result revealed that the different processing methods resulted in increase in the crude protein contents with a corresponding reduction in crude fibre of the seed hull. The changes observed must have been due to fermentation that occurred during the soaking of the seedhull.

“…Berbagai perlakuan fisik dan kimia telah dilakukan sebagai usaha untuk meningkatkan nilai dan manfaat limbah pertanian terutama jerami padi. Percobaan pada domba menunjukkan, bahwa perlakuan fisik dengan penggilingan berhasil meningkatkan koefesien cerna dan produk fermentasi karbohidrat (asam lemak atsiri) dalam rumen (Willis et al, 1980). Penggilingan menyebabkan : (1) pemecahan lapisan kulit (lignin dan silikat), sehingga mikroba rumen dapat langsung mencerna selulosa; (2) memperluas permukaan partikel bahan pakan, sehingga frekuensi kontak antara enzim dengan partikel meningkat.…”

“…Hasil dari berbagai percobaan, baik secara in vitro maupun in vivo menunjukkan, bahwa perlakuan kimia dengan hidrolosis asam, basa, maupun kombinasinya berhasil meningkat koefesien cerna jerami padi (Rexen dan Thomsen, 1976;Jackson, 1977;Coombe et al, 1979;Willis et al, 1980) Hidrolisis asam umumnya dilakukan dengan H Z S0 4 dan hidrolosis basa dengan NaOH; walaupun perlakuan kimia ini berhasil meningkatkan koefesien cerna jerami padi dari 40 menjadi 70 persen, tetapi masih terdapat beberapa faktor pembatas diantaranya: (1) biaya terlalu tinggi, karena mahalnya harga H 2 SO 4 maupun NaOH;…”

The quality improvement of rice straw, rice bran and cassava waste by fermentation of fungi and yeast ABSTRACT. Biomass of agricultural residues are highly potential as ruminant feedstuff. However, it is characterized by high content of indigestible fiber and low nutritive value, due to the strong hydrogen bonds in the lignocelluloses. Biological treatment by using microbes seems to be an alternative, because of the capability, with no pollution problem. An experiment has been conducted to seek for the fungi and yeast which capable to improve the quality of rice straw, rice bran and cassava waste. The trial was done by the technique of in sacco and in vitro, in a completely randomized block design. The variables measure were : dry matter and protein digestibility, protein solubility and nutrient composition of the fermentation product. Based on the all variables measure, the current study concluded that the microbes chosen were : monoculture of T. viride for rice straw, monoculture of A. niger for rice bran and biculture of A luchuensis and S. cereviseae for cassava waste.
