Abstract: SUMMARY: Four experiments were set up to evaluate the suitability of fermented blood meal (FBM) in pig diets. Experiment one evaluated the effect of inoculation on rate of fermentation. Previously fermented blood meal was used as the inoculant replacing quantities of fresh blood-molasses mixture at levels of l0 to 90%. The experiment had 9 treatments with three replicates each arranged in a completely randomized design. Experiment two compared growth rates supported by diets containing wet or dry FBM. The experiment was a 2 x 2 factorial using l2 pigs with equal sex distribution. Experiment three assessed the utilization of F BM by pigs in a digestibility and nitrogen balance study. Four male castrates arranged in a 4 x 4 Latin square were used in the experiment. Experiment four sought to establish the optimum inclusion level of fermented dry blood meal (FDBM). Sixteen growing pigs blocked on sex and weights were used in the experiment in a completely randomized block design. There were four treatments each with 4 replicates. In experiment one, all the treatments with inoculants had a faster rate of pH drop than the control. All the inoculated samples attained a pH of 4.2 in less than five days While the control took seven days. In experiment two using wet or dry FBM in pig rations did not affect average daily gain (ADG). or feed conversion ratio (FCR) but the diet with wet blood meal supported higher feed intake than the diet with dry blood meal. Females had a better FCR than the males. In experiment three, substituting soybean meal (SBM) on CP basis with 10% of either fermented wet bloodmeal (FWBM) or FDBM significantly reduced dry matter (DM) digestibility of the diets but did not affect nitrogen (N) digestibility. Nitrogen retention (NR) and biological value (BV) were similar for the three test diets. N digestibility for FWBM and FDBM was also similar to N digestibility in SBM (44% CP). In experiment four. the rate and efficiency of gain for pigs receiving 5% and 1 1% FDBM were similar while Fl was significantly reduced at 11% FDBM. Pigs receiving 7 and 9% FDBM ate more than the pigs receiving 5 or 11% FDBM. ADG and FCR were however similar for all the levels of substitution. Males in this experiment ate more and grew faster than the females but were similar in F CR. Key words: Fermented Blood meal. Growing pigs. pH, Nitrogen retention, Digestibility.
