dc.description.abstract [EN] Effects of feed composition, addition of the probiotic Acid-Pak 4-Way (AP4W), sex, age at slaughtering (53 or 67 d.) and interactions between feed and AP4W, age and feed, age and AP4W and age and sex on gastrointestinal (GI) tract weight and dressing percentage of 84 weaned New Zealand White rabbits were studied. Three complete feed mixtures with different levels of digestible energy (DE, MJ/kg of feed) and ADF content (g/kg of dry matter-DM) were tested (feed 1 had recommended DE and high ADF content: 9.22 MJ DE and 299 g ADF; feed 11 had 11.60 MJ DE and 254 g ADF; feed 111 had high energy and recommended ADF content: 13.14 MJ DE and 187 g ADF), each with and without the addition of 0.5 % AP4W. High-energy/recommended-ADF diet (feed 111) increased carcass weight (1 : 970ª ; 11: 976ª ; 111 : 1005bg; P:S:OJ>5), improved dressing percentage (1 : 50.2ª, 11 : 50.6ª , 111 : 52.0 %, P:S:0.05), decreased GI weight (1 : 411.1ab, 11 : 420.2ª, 111 : 391.3b g, P~.05) and decreased caecum weight (1 151.3ª, 11 148.8ª, 111 133. 7 g, P:S:0.05). The proportions of small intestine and caecum (of total GI weight) differed between feed 1 and 111 (% of small int.: 20.2 vs. 22.3; % of caecum: 36.9 vs. 34.0, P:S:0.05). The effect of AP4W was observed only in the decreased proportion of stomach and increased proportion of caecum (% of stomach: 28.0 vs. 29.9, % of caecum: 36.2 vs. 34.8 %, (P:S: 0.05). Sex significantly (P:S:0.05) influenced caecum weight (females: 151.1, males 138.2 g), % of caecum (f. 36.6, m. 34.4 %) and % of small intestine (f. 20.7, m. 21.7 %). Older rabbits had (P:S:0.05) better dressing percentage (52.0 vs. 49.9 %), higher carcass weight (1007 vs. 961 g), lower GI tract (392.7 vs. 422.4 g) and small intestine weight (80.0 vs. 9~.1 g), higher weight and % of large intestine (63.0 vs. 54.8 g, 14.9 vs. 13.8 %). es_ES
dc.description.abstract [FR] Avec 84 lapins Néo Zélandais Bienes sevrés a 32 jours, ont été étudiés les effets, sur le poids du tractus gastrointestinal et le rendement a l'abattage, de la composition de l'aliment, de l'addition d'un probiotique Acid-Pak 4-Way (AP4W). du sexe, de /'~ge a l'abattage (53 ou 67 jours) et les interactions entre l'aliment et l'addition de AP4W. /'~ge et l'aliment, /'~ge et AP4W et /'~ge et le sexe. Trois aliments complets a niveaux d'énergie digestible (ED, MJ/kg) et contenu en ADF (glkg MS) différents ont été testés (aliment I : 9.22 MJ ED et 299g ADF; aliment /1 : 11.6 MJ ED et 254g ADF; aliment 111: 13.14MJ ED et 187g ADF), chacun d'entre eux étant doublé par le m~me aliment additionné de 0.5% d'AP4W. L'aliment 111 haute énergie & taux d'ADF leflus bas augmente le poids de carcasse (I : 97a8 ; 11: 97ft ; /1 : 1005'g ; PS0.05), améliore de rendement a l'abattage (1 : 50.~ ; /1 : 50.ft ; /11 : 52.d' (j. PS0.05), diminue le R.Oids du tractus r¡astrointestinal (1 : 411.1ª, 11: 420.°2", 111 : 391.3" q¡, PS0.05) et d1cninue le poids du caecum (1 : 151.J8 ; 11 : 148.ir ; /11 : 133.7" g, PS0.05). Les proporlions de l'intestin grOle et du caecum différent avec les aliments I et /11 (% d'intestin grOle : 20.2 vs 22.3 ; % de caecum : 36.9 vs 34.0, Ps0.05). On observe un effet d'AP4W entra1nant la diminution de la proporlion de l'estomac et l'augmentation de la proportion du aaecum (% de /'estomac : 28.0 vs 29.9 ; % du caecum: 36.2 vs 34.8, Ps0.05). Le sexe influence significativement (Ps0.05) le poids du caecum (feme/le : 151.1; males : 138.2 g) le pourcentage du caecum (f. : 36.6; m. : 34.4 %) et le pourcentage d'intestin grOle (f. : 20.7; m. : 21.7 %). Les lapins les plus ~gés ont un meilleur rendement a l'abattage (Ps0.05) (52.2 vs 49.9 %), des carcasses plus lourdes (1007 vs 961 g) une diminution du poids tractus gastrointestinal (392. 7 vs 422.4 g) et de l'intestin grOle ( 80. O vs 92. 1 g) et un gros intestin plus lourd et proporlionnel/ement plus important (63.0 vs 54.8 g, 14.9 vs 13.8 %).
