Abstract: ULEP, LETTY JUNE LAURICO. University of the Philippines at Los Banoss, April, 1982. The Procduction Processing and Evaluation of the Nutritive Value of the Earthworm (Perionvx excavatus) as Feed for Broilers. Major Professor: Dr. Perla L. Lopez A study was conducted to determine the chemical composition of the earthworm Perionyx excavatus and evaluate its nutritional value for broilers. Earthworm meal contained approximately 60% crude protein, 0.56% calcium, 0.82% phosphorus, 2.65% lysine, 0.57% methionine and 1.74% cysteine, on dry matter basis. Metabolizable energy is 3905 kcal/kg and metabolizable crude protein is 43%. Cattle manure as substrate was good for earthworm multiplication while swine manure and water hyacinth leaf pulp were better for growing the young earthworms Production of earthworm in combinations of rice straw, rice bran and sawdust was better than other mixtures. The weight of earthworms was doubled in 31 days. Earthworm meal preparation by air dehydration and blanching followed by sun drying gave the highest percentage recovery. Feed consumption of broilers fed the three levels of earthworm meal diets was comparable to the 10% and 5% inclusion of MBM and FM, but significantly lower (P‹ .01) compared to the feed consumption of broilers fed the SBOM diet, 3% MBM and FM and the commercial ration. Body weight of birds from the three levels of EWM, 10 and 5% FM, the SBOM diet and commercial ration were comparable. Feed conversion efficiency of birds on 5% EWM was not different from 1 0% EWM and FM and 3% EWM. The incorporation of the earthworm meal at any level in the diet of broilers was favorable in all measures than fish meal, meat and bone meal and soybean oil meal except for the slightly lower body weight at 8 weeks than the commercial diet which was statistically insignificant. Earthworm meal can be recommended to be incorporated in the diets of broilers if mass production can be made economical

A study was conducted to determine the chemical composition of the earthworm Perionyx excavatus and evaluate its nutritional value for broilers.
Earthworm meal contained approximately 60% crude protein, 0.56% calcium, 0.82% phosphorus, 2.65% lysine, 0.57% methionine and 1.74% cysteine, on dry matter basis. Metabolizable energy is 3905 kcal/kg and metabolizable crude protein is 43%.
Cattle manure as substrate was good for earthworm multiplication while swine manure and water hyacinth leaf pulp were better for growing the young earthworms
Production of earthworm in combinations of rice straw, rice bran and sawdust was better than other mixtures. The weight of earthworms was doubled in 31 days.
Earthworm meal preparation by air dehydration and blanching followed by sun drying gave the highest percentage recovery.
Feed consumption of broilers fed the three levels of earthworm meal diets was comparable to the 10% and 5% inclusion of MBM and FM, but significantly lower (P‹ .01) compared to the feed consumption of broilers fed the SBOM diet, 3% MBM and FM and the commercial ration. Body weight of birds from the three levels of EWM, 10 and 5% FM, the SBOM diet and commercial ration were comparable. Feed conversion efficiency of birds on 5% EWM was not different from 1 0% EWM and FM and 3% EWM.
The incorporation of the earthworm meal at any level in the diet of broilers was favorable in all measures than fish meal, meat and bone meal and soybean oil meal except for the slightly lower body weight at 8 weeks than the commercial diet which was statistically insignificant. Earthworm meal can be recommended to be incorporated in the diets of broilers if mass production can be made economical
