Feeding Value

The high content of lignin in cell walls is the major limiting factor in the digestion and utilisation of cereal crop residues by ruminants. The aim of this study was to evaluate the effectiveness of the white rot fungus, Pleurotus ostreatus (P. ostreatus), to degrade lignin and to enhance the rumen degradability of maize stover, rice straw, wheat straw and their mixture in equal proportion on a dry-matter (DM) basis. Four samples of each substrate were incubated aerobically in triplicate with P. ostreatus for 0 (Control), 21, 28 and 35 days under solid-state conditions (temperature, 24°C; humidity, 70 ± 5%). The changes in chemical composition, DM and nutrient losses, and rumen fermentation characteristics using in vitro DM digestibility (DMD) and the in vitro gas-production (GP) technique were measured. The results showed that incubation with P. ostreatus decreased (P < 0.001) the contents of neutral detergent fibre and lignin with a concomitant increase (P < 0.001) in the contents of ash and crude protein. The losses of nutrients differed (P < 0.001) among the straw types, with rice straw and maize stover showing the largest (P < 0.05) lignin degradation compared to wheat and mixed straws. The DMD and 72-h cumulative GP increased (P < 0.001) consistently with increasing fungal incubation period and for all substrates the highest values of DMD and GP were measured after 35 days of incubation with P. ostreatus. The lignin degradation was strongly associated with hemicellulose degradation (r = 0.71) across the various straws. Results of the present study demonstrated that incubation of low-quality crop residues with P. ostreatus under solid-state conditions upgrades their feeding value by reducing the content of lignin and increasing the content of crude protein and ruminal degradation.

An investigation of the production and utilization of crop residues for ruminant feeding in five villages within Aliero Local Government Area of Kebbi State was carried out using a structured questioner which was administered to 75 respondents. The data collected was analyzed by using simple statistical tool such as frequency distribution and percentage. The study revealed that 47.95% of the respondents were farmers with more than half (52.41%) had 5-8 members in their family. Mixed farming is common to all the respondents with cereal and legumes crops combination alongside with cattle, sheep, and goats rearing. Some crop residues such as maize stover, rice straw, etc are available all year round since they are generated both at rainy and dry season in the study area. Maize/sorghum/millet stovers and groundnut/cowpea straws plays a major part in ruminant feeding in the study area. The level of cultivation, production and utilization of crop residues as observed in this study depends on the land size, season of production and flock size amongst others. Most of the respondents (39.74%) source their crop residues from self-production and the type of crop residues are those from groundnut/cowpea straws, maize/millet/sorghum stovers and rice straws. The present study revealed the potential of crop residues not only as ruminant feeding but also as a means of livelihood among the respondents.
