Abstract Iniguez-Covarrubias, G., Franco-Gomez, Ma, de J. and Andrade- Maldonado, Gpe. del R. 1994. Biodegradation of swine waste by house fly larvae and evaluation of their protein quality in rats. J. Appl. Anim. Res., 6: 65–74. Swine waste was converted into a high-protein product by upgrading with housefly larvae. Fresh manure was seeded with housefly eggs. The eggs were allowed to hatch and the larvae to tunnel and aerate the manure. This process deodorized the manure by the 6th or 7th day. The larvae migrated out of the manure to a dry box. The larvae were dried, ground and used in rat feeding tests for the evaluation of the protein quality in terms of protein efficiency ratio (PER), the in vitro digestibility value of larvae meal protein was also determined. The larvae meal contained 52.5% C.P. of 90.6% digestibility with very high (29.1) percent of ether extract. It supported growth in rats as good as casein with PER 3.3 as against 3.1 for casein. If found economically viable on large scale, the pr...
