The percentage meal recovery and zoochemistry of chicken and pig by-products in comparison to microbials, soybean meal, fish and skin milk meals for ruminatia rations revealed that the chicken and pig by-products have comparable crude protein with equivalent convertional feed materials. Where the crude protein of chicken and pig blood stands at 93.69%, the energy levels of the by-products are similar with those of the convertional feeds. Hence the total carbohydrates were low among the chicken and pig by-products, it appears to cause no disturbance to total digestability. The fats of the by-products are high with the exception of those of the chicken and pi g blood (below 1.5%). Mineral composition of these by-products are similar to equivalent convertional feedstuffs. These by-products appear to be adequate in all the essential amino acids which is the index of the crude protein composition.
