Abstract

The objective of the present study was to correlate farmers’ perception (FP), sheep preference (SP) and laboratory analysis (LA) of nutritional quality of stored grain legume fodders (GLFs). The GLFs of cowpea, groundnut and soybean were stored at 3-locations (rooftop, room and treefork) in -packaging types (polythene sacks or tied with ropes) for 120 days. FP was assessed by scoring the perceived quality of GLFs on a scale of 1 to 10 (1=bad and 0=good) based on physical appraisal by a group of farmers. SP was assessed by cafeteria feeding trial based on dry matter intake (DMI) of GLFs by a flock of 12 sheep during a 14 hr period. For LA, Organic Matter Digestibility (OMD) and Crude Protein (CP) content were assessed by Near Infra-Red Spectroscopy (NIRS). Cowpea scored higher FP (6.3) and SP (66 g DMI/14hr/sheep) than
groundnut (FP 5.5 and SP 59 g DMI/14hr/sheep) and soybean had lowest FP (2.3) and SP (39 g DMI/14hr/sheep). However, LA indicated that groundnut had higher CP content (140 g kg DM) than cowpea (115 g kg DM) and soybean (98 g kg DM). OMD, on the other hand, was higher in cowpea (686 g kg DM) than groundnut (659 g kg DM) and soybean (574 g kg DM). CP was positively orrelated with FP (r=0.35) and with SP (r=0.48). Similarly, OMD was positively correlated with FP (r=0.50) and with SP (r=0.70). Room storage had higher FP and SP than rooftop and treefork. Sack storage scored higher than tied on FP, SP and LA. The present study demonstrated that it is possible to used FP and SP to predict the nutritional quality of GLFs.
