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 interactlons between feed and the addltion of AP4W, age and feed, age and AP4W and age and sex on the fermentation pattem in the caecum of 84 weaned New Zealand Whlte rabblts were studied. Three complete feed mixtures with different levels of digestible energy (DE, in MJ/kg of feed) and ADF content (in g/kg dry matterDM) were tested (feed 1 had recommended DE and h1gh ADF content: 9.22 MJ and 299 g ADF; feed 11 had 11.60 MJ and 254 g ADF; feed 111 had high DE and recommended ADF content: 13.14 MJ and 187 g ADF), each with and without the addltion of 0.5 % AP4W. High-energy/recommended-ADF diet (fe~ 111) sign~·c antly (Ps:0.05) decreased the pH value (1 : 6.398 , 11 : 6.21 111 : 6.09 increaseg, the molar proportion of n-butyric acid (1 : 10.3•, 11 : 11. , 111 : 12.6 %) and decreased molar% of propionic acid (I : 7.o•, 11 : 6.2•b, 111 : 5.7b %) in th! caecum co~ents. A decreased DM content (1 : 226.1•, 11 : 212.2 , 111 : ¡>7.9 g/kfQ and an increased ammonia leve! (1: 13.3ª, 11 : 13.8 , 111 : 16.6 mmol/kg) had no negative influences on zootechnical parameters. The addition of AP4W had no influence on the parameters tested. Age at Jlaughter influe9ced the dry matter caecum content (53 days: 210.9", 67 d.: 219.9 g/kg, Ps:0.10). In older animals (67 days) differences in the proportions of VFA between female and mafe rabblts were significant (mol% of acetic acid: f!li,males 78.3ª, males 81.0b %; mol% of propionic acid: f. 7.3•, m. 5.6 %), indicating that there were sorne differences in the microbial fermentation pattem of the caecum between females and males. es_ES
dc.description.abstract [FR] Les effets sur le profil fennentaire caecal de la composition de l'aliment, de l'addition d'un probiotique Acid-Pak 4-Way (AP4W), du sexe, de /'age 8 l'abattage (53 ou 67 jours) et les lnteractions entre l'aliment et l'addition de AP4W. l'age et l'aliment, /'age et AP4W et rage et le sexe ont été étudiés sur 84 laplns Néo Zélandais Bienes sevnts 8 32 jours Trois aliments composés avec des niveaux d'énergie digestible (ED : MJ/kg) et contenu d'ADF (g/kg MS) dlfférents ont été testés (aliment I : 9.22 MJ et 299g ADF; aliment /1 : 11. 60 MJ et 254g ADF; aliment /11 : 13. 14 MJ et 187g ADF) chacun d'entre eux étant doublé par le mOme aliment additionné de O. 5 % d'AP4W. Le ntgime haute énergie & ADF faible (aliment 111) diminue significat~ement (Ps0.05) la valeurdu pH caecal (/: 6.3g9; 11: 6.21b ; 111: 6.011), augmentebla proportlon molécula/re d'acide n-bufyrique (/ : JO.;t ; /1 : 11.;t ; /11 b: 12.fl' %) et dimlnue le % d'acilde prop1omque (/ : 7.<f ; /1 : 6.;t ; /11 : 5. 7° %) dans le contenu caql. Une dimim,Jtion du contenu en matiére sache(/: 226.1•; 11: 212.Z'; 111: 207.g' glkg) et une augcnentation du taux d'ammoniaque (/ : 13.J8 ; /1 : 13.(J"b ; /11 : 16.6" mmoVkg) ont été /es conséquences regrettables de /'a/lment 111. L 'addition de AP4W n'a pa eu d'influence sur les paramétres enregistnts. L'age 8 l'abattage inf/uence la teneur en MS caeca/e (53 jours : 210.~ ; 67 jours : 219.9" rYkg; PS0.10). Chez les animaux les plus agés (67 jours) les dlfférences entre males et feme/les pour les taux d'acides gras volatU~ ont été significatives (acide scétlque: feme/le:¡ 78.J8; males 81.fl' %, aclde propionique : feme/le 7.3"; males 5.6" %) indlquant une différence dans le schéma de fennentation caecale entre males et feme/les.
