“…leaves were in the range reported by Skerman (1982). The N content of Leucaena leucocephala and Calliandra calothyrsus was respectively lower and higher than values previously reported by Teguia et al (1999) for samples from the same farm plots. The difference may be attributed to the age of leaves.…”

The effect of fcedrngArachis glabrata, Leucaena leucocephala, Calliandra calothyrsus or Desmodium spp. leaves to commercial layer on egg production and yolk colour was compared with the effect of feeding an artificial yolk pigmentor (Carophyl ®). Percent hen-day production averaging 77.4 and 74.7%, respectively for hens fed on Desmodium spp. and Leucaena leucocephala leaves, were significantly (PO.05) higher than egg production in the control group. No significant difference was recorded among treatment groups for shell thickness. Yolk colour in groups fed forage leaves ranges between 6.76 and 9.83 and was significantly better than in control group (2.35). It was concluded that any of the studied forage leaves could be used to supply xanthophyll to commercial layers with no detrimental effect on egg production and quality.

“…The fast rate obtained in POB could probably be influenced by carbohydrate fractions readily available to the microbial population (Chumpawadee et al, 2007). The higher degradation of the insoluble fraction (b ml) in the control (19.00) than the treated bagasse, though contrary to expectations, has been previously reported (Teguin et al, 1999;Melaku et al, 2003). Melaku et al, (2003) suggested that this phenomenon could be due to the rapid rate of gas production leading to substrate exhaustion and limitation on the extent of gas production in the control.…”

Solid fermentation using celllolytic fungi: Pleurotus sajor-caju and Pleurotus florida for upgrading of sugarcane bagasse to value-added ruminant feed were investigated. The fermentation of the substrate lasted for 21 days after which the changes in the chemical and mineral composition, and the in vitro gas production were evaluated. The results obtained showed an increase in the crude protein (%) from 6.43 (control) to 9.82 for Pleurotus sajor treated substrate (PSB) and 10.05 for Pleurotus florida treated substrate (PFB). The treatment effect on crude fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) was significant. Fungal treatment decreased crude fiber (%) from 37.49 (control) to 31.67 (PFB), NDF (%) from 65.92 (control) to 53.34 (PSB), ADF (%) from 49.94 to 34.79 (PSB), and ADL (%) from 15.13 to 9.74 (PSB). Most of the major and trace minerals were higher in the untreated bagasse with the exception of phosphorus (0.15g/kg), magnesium (1.80g/kg), potassium (2.70g/kg) and zinc (21.60g/kg). The degradation of the insoluble but degradable fraction (b, ml) was higher in the control (19.00) followed by PSB (16.00). The estimated organic matter digestibility (%), short chain fatty acid (µ, mol) and metabolisable energy (MJ/Kg DM) increased from 38.77-50.06, 0.56-0.75 and 5.33-6.80 respectively. The gas volumes at 24h, 48h and 72h as affected by treatment was significant (P<0.05) with more volumes of gas produced in the treated bagasse. The result obtained in this study showed that fungal treatment of bagasse improved the nutrient contents and digestibility.

“…The chemical composition did not vary much from values published in the literature for the browse species (Teguia et al, 1999;El hassan et al, 2000). The browses had high CP content, which would indicate their high nutritive value, since the browses are intended to be used as protein supplements for low quality tropical pastures and crop by-products, which are low in protein.…”

and S. sesban. The browses were evaluated by their chemical composition including phenolics, in vitro gas production and tannin activity (tannin bioassay). All the species had high crude protein content (149-268 g/kg DM) and low NDF content (239-549 g/kg DM). The feeds had varying contents of total extractable tannins (TET) ranging from low (3-22 mg/g DM), moderate (42-58 mg/g DM) and high (77-152 mg/g DM). Calliandra calothyrsus had the highest tannin content. Significant (p<0.05) variation in gas production was recorded among the species. Sesbania micrantha had the highest (p<0.05) potential gas production while Gliricidia sepium had the highest (p<0.05) rate of gas production. Use of polyethylene glycol (PEG 6000), to assess the adverse affect of tannins, indicated that tannins in browse species with high tannin content had inhibitory effects on rumen microbial fermentation as indicated by the gas production. Estimated organic matter digestibility and metabolizable energy also increased with PEG addition. The results of this study indicate that such Kenyan browse species have the potential to be used as feed supplements for ruminant animals.
