Abstract

A study was conducted to evaluate the levels of tannins in legume grains (LG) [(soybean (Glycine max), pigeon pea (Cajanus cajan) and Cowpea (Vigna unguiculata)] their effects on trypsin activity and performance of rabbits (Oryctolagus cunniculus). The Flemish Giant (FG) breed was used in the study. Eighteen rabbits weaned at six (6) weeks of age were used out of which six (6) were assigned to ration 1(containing 31.6% soybean), six (6) to ration 2 (containing 72% cowpea) and another six (6) to ration 3 (containing 70.18% pigeon pea). The three (3) (LG) used [soybean (SB), pigeon pea (PP) and cowpea (CoP)] were roasted to reduce trypsin inhibition (TI) before feeds were compounded. The effectiveness of the roasting in reducing TI in the legume grains: SB, PP and CoP were 93%, 52.48% and 82.24% respectively. The effectiveness of roasting in reducing TI in the SB, PP and CoP differed significantly (p˂0.05). The raw legume grains (RaLG), roasted legume grains (RoLG) and the three (3) rations (1, 2 and 3) were analysed for TI level. All the three (3) RaLG differed significantly (p˂0.05) in TI (87.94% for raw SB, 72.73% for raw CoP and 69.27% for PP. Similarly, the three (3) RoLG differed significantly (p˂0.05) in TI (5.87% for roasted SB, 34.56% for roasted CP and 12.30% for roasted PP). Rations 1, 2 and 3 were found to have 1.72%, 20.40% and 8.26% TI, respectively and these values differed significantly (p˂0.05). RaLG, RoLG and the three (3) rations (1, 2 and 3) were analysed for tannin content (TC). The RaLG differed significantly (p˂0.05) in TC (0.33% for SB, 0.40% for PP and 1.13% for CoP). Similarly, RoLG differed significantly (p˂0.05) in TC (0.72% for SB, 0.78% PP and 1.79% for CoP). Rations 1, 2 and 3 were found to possess 0.13%, 0.15% and 0.57% TC respectively.
