Rev. mex. de cienc. pecuarias [online]. 2021, vol.12, n.1, pp.151-162.  Epub 20-Set-2021. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v12i1.5455.

This study aimed to evaluate the effect of feeding rabbits with silkworm pupae and mealworm larvae meals on their performance indicators. Ninety (90) rabbits were divided into three groups. Control group (C) was fed with 10% soybean meal (SBM), SPM group received the diet including 5 % SBM and 4 % of silkworm pupae meal, and MLM group received the diet including 5 % SBM and 4 % of mealworm larvae meal. The body weight of rabbits and average daily gains were determined. Feed conversion ratio (FCR) was calculated. At the end of fattening period, the animals were euthanized, skinned and eviscerated to determine their carcasses characteristic. Hind leg and loin muscles were collected for analyses of the chemical composition. At the end of fattening period, rabbits from groups SPM and MLM were heavier than C rabbits (2,606.5 and 2,584.8 vs 2,404.0 g), which also improved their overall carcass characteristic while FCR was similar between groups. However, feeding rabbits with the addition of insect's meals increased the amount of ether extract in their muscles. Based on the results obtained, it may be concluded that SBM may be partially replaced by silkworm pupae and mealworm larvae meals in rabbit diets.
