A comparative study on the effect of quantitative feed restriction in males and females of broiler chickens, rabbits and nutrias. I. Performance and carcass composition

The aim of the study was to compare effects feed restriction on growth performance and carcass composition chicken, rabbit nutria males females. Feed applied at a rate 70% ad libitum from 14 21 days age in chickens, 42 49 rabbits, 12 15 weeks nutrias. Animals were fed prior following restriction. Carcass evaluated common slaughter ages, i.e., 31 70 eight months results showed stronger restriction, sex, their interaction broiler chickens than rabbits In increased sex differences final body weight, which associated with (P = 0.009). as fixed factor significantly affected conversion it no effect negligible all selected species. With respect significant observed daily weight gain, dressing out percentage breast percentage, loin nutrias perirenal fat percentage. Results indicated that interactions might be short realimentation period.
