66.0, fat 21.8% and cyanide 23.4 mg/kg DM). The diets were supplemented with dried whole fresh water fish to contain 19 % crude protein (Nx6.25). Growth and feed conversion were studied over a 6 week period Digestibility was measured by the acid insoluble ash inert marker method when the average weight of the pigs reached 20 kg.
There was no effect of the level of rubber seed meal on feed intake, growth rate and feed conversion. Crude fat digestibility was high and increased linearly with increasing levels of rubber seed meal in the diet. Apparent digestibility of dry matter, organic matter, NDF and crude protein was not influenced by the level of ground rubber seeds in the diet..
Key words: Pigs, growth, conversion, digestibility, rubber seed meal
