Abstract

This study was conducted to evaluate the carcass characteristics and hepato-histopathological examination of Hyla rabbits fed graded levels of watermelon rind-wheat offal mix. In a sixteen-week trial, 45 Hyla rabbits of 5-6 months of age with an average weight of 1.84±0.01kg were allotted to five dietary treatments containing 0, 10, 20, 30 and 40% of watermelon rind-wheat offal mix levels in a completely randomized design with nine rabbits per treatment. Four rabbits were randomly selected from each treatment group and slaughtered for carcass evaluation and histopathological changes in the kidney and liver. Watermelon rind-wheat offal mix (WRWO) had no significant (P>0.05) effect on the carcass characteristics except in the live weight and bled weight of Hyla rabbits. Rabbits fed T4 had the highest live weight value (2.36kg) which was significantly higher (p<0.05) than others. Rabbits in T4 had a significantly higher (P<0.05) value (2.02kg) for bled weight than that of rabbits in T2 (1.53kg). It was concluded that watermelon rind-wheat offal mix can be included in the diets of Hyla rabbits up to 40% without adverse effect on their carcass characteristics and hepato-histopathological examination.

 

 

 

 

Cette étude a été menée afin d'évaluer les caractéristiques des carcasses et l'examen hépato-histopathologique de lapins Hyla nourris avec un mélange écorce de pastèque-abats de blé à teneurs graduées. Lors d'un essai de seize semaines, 45 lapins Hyla âgés de 5 à 6 mois, pesant en moyenne 1,84 ± 0,01 kg, ont reçu cinq traitements alimentaires contenant 0, 10, 20, 30 et 40 % de mélange écorce de pastèque-abats de blé, selon un protocole entièrement randomisé, avec neuf lapins par traitement. Quatre lapins ont été sélectionnés aléatoirement dans chaque groupe de traitement et abattus pour une évaluation de la carcasse et des modifications histopathologiques des reins et du foie. Le mélange écorce de pastèque-abats de blé (WRWO) n'a eu aucun effet significatif (p > 0,05) sur les caractéristiques de la carcasse, sauf sur le poids vif et le poids saigné des lapins Hyla. Les lapins nourris au T4 présentaient le poids vif le plus élevé (2,36 kg), significativement plus élevé (p < 0,05) que les autres. Les lapins du T4 présentaient un poids saigné significativement plus élevé (p < 0,05) (2,02 kg) que celui des lapins du T2 (1,53 kg). Il a été conclu que le mélange écorce de pastèque-abats de blé pouvait être inclus dans l'alimentation des lapins Hyla jusqu'à 40 % sans effet néfaste sur les caractéristiques de la carcasse et l'examen hépato-histopathologique.
