Two experiments were conducted with fifty-four 9-week
old Bovan Nera pullets (24 in experiment 1 and 30 in experiment 2) to
determine the effect of processing on the nutrient utilization of pigeonpea
seed meal (PSM) and PSM-based diets by pullets. The seeds were processed
either as boiled, toasted, soaked or raw (unprocessed). In experiment
2, raw or processed PSM were each included as 10% of a maize-soybean
diet. Parameters considered were DM, CP, CF and ether extract utilization
of the PSM and that of PSM-based diets. Results showed that in experiment
1, processing significantly increased (P<0.05) CP retention of the pullets
while boiled and raw PSM had significantly higher (P<0.05) CF utilization
than toasted and soaked. In experiment 2, boiled PSM diet significantly
improved (P<0.05) CP retention of the pullets, while soaked PSM diet
significantly reduced both CP retention and CF utilization of the pullets.
It was concluded that processing of pigeonpea seeds for use in pullet
diets would improve CP retention and other nutrient utilization especially
boiling and toasting.
