CASSAVA AS NEW ANIMAL FEED IN EGYPT 3 - PELLETED COMPLETE CASSAVA FEED FOR GROWING RABBITS

[EN] Forty New Zealand White rabbits (20 males and 20 females) aged 5 weeks, of 735g in average weight, were divided into two groups on basis of weight and sex. A pelleted complete rabbit feed containing 45 % cassava products (CCF diet) as 30 % root meal + 15 % leaf meal, was formulated to be fed in comparison with a commercial feed (AF diet ; Atmida Cº) during the 15 weeks of experiment, divided in 3 stages of 5 weeks. 1 % urea was added to the CCF diet in arder to increase the N-content. The results indicated that CP digestibility and N-balance of CCF were significantly (P<0.05) lower than that in AF diet in the first 5 weeks after weaning (1st stage). But the CP digestibility and N-balance were not significantly different between two Qroups fed CCF and AF diets at 15 weeks after weaning (3rá stage). The CF digestibility was not significantly affected by type of feed and it was improved by advance in age of rabbits fed CCF or AF diets. In contrast N-balance was decreased with advancing of age of two groups of growing rabbits. No significant effect of sex was observed on digestibility or N-balance. The feed intake was significantly (P<0.01) lower with CCF diet than that with AF diet in 1 st and 2nd stages. Daily body gain was significantly (P<0.01) lower with rabbits fed CCF than those fed AF diets in 1 st stage but it was nearly similar between two groups at 2nd and 3rd stages. Feed conversion (feed/gain) was more efficient with rabbits fed AF than those fed CCF diets at 1 st stage but opposite trend was observed in 2nd and 3rd stages of growth. Slaughter and carcass traits showed no significant differences between the two groups fed CCF and AF diets. There were no significant differences in feed intake, feed conversion and daily body gain between male and female rabbits. Conclusively, it could be appear that cassava products (roots and leaves) can be used satisfactorily as the partial substitute for traditional energy and protein supplements to formulating pelleted diet for growing rabbits.[FR] Quarante lapins Néo-zélandais Blancs (20 males et 20 feme/les) agés de 5 semaines, pesant en moyenne 735g ont été divisés en deux groupes compte tenu de leur sexe et de leur poids. lis ont rer;u au cours des 15 semaines d'expérience, soit un aliment granulé complet (CCF) contenant 45 % de manioc (30 % de farine de racines et 15 % de farine de feuilles) soit un aliment complet (Atmida CJe) du commerce (AF). 1 % d'urée a été ajouté au régime CCF afin d'augmenter la teneur en azote. Les résultats indiquent que la digestibilité des PB et le bilan azoté du régime CCF etaient significativement plus bas que ceux du régime AF dans les 5 premiares semaines apres le sevrage (1 ere période). Mais la digestibilité des PB et le bilan azoté n'étaient pas significativement différents entre les deux groupes (CCF et AF) 15 semaines apres le sevrage (3eme période). La digestibilité de la cellulose brute n'était pas affectée par le régime, par contre, elle s'est améliorée avec l'age. A l'inverse, le bilan azoté s'est dégradé avec l'age, au sein des deux lots. Aucun effet de sexe n'a été observé pour la digestibilité ou le bilan azoté. La consommation était significativement plus basse (P<0.01) avec le régime CCF qu'avec le régime AF au cours des 1 ere et 2eme périodes. Le gain de poids journalier était significativement plus bas avec l'aliment CCF qu'avec l'aliment AF au cours de la premiare période mais il était presque identique dans les deux groupes au cours des 2eme et 3eme périodes. L'efficacité alimentaire était supérieure avec l'aliment AF comparé a l'aliment CCF pendant la premiare période, mais une tendance contraire a été observée durant la 2eme et 3eme périodes de croissance. Les caractéristiques d'abattage et de carcasse ne présentaient pas de différences significatives entre les deux groupes. 11 n'y avait pas de différences significatives entre males et feme/les concernant la consommation, /'indice de consommation et le gain de poids journalier. En conclusion il apparait que le manioc (feuilles et racines) peut etre utilisé de maniere satisfaisante comme substitut partiel des composants traditionnels énergétiques et azotés dans des formules d'aliments granulés pour lapins en croissance.Abd El-Baki, S.; Nowar, M.; Bassuny, S.; Hassona, E.; Soliman, E.

Digestibilidade aparente dos nutrientes de dietas simplificadas baseadas em forragens para coelhos em crescimento Apparent digestibility of nutrients of simplified diets based on forages for growing rabbits

Avaliaram-se os efeitos de dietas simplificadas à base de forragens sobre a digestibilidade aparente dos nutrientes em coelhos Nova Zelândia branco. As dietas experimentais foram: referência (REF), feno de alfafa (FAL), feno das folhas de rami (FRA), feno das folhas de amoreira (FAM) e feno do terço superior da rama da mandioca (FMA). A digestibilidade das dietas foi influenciada pelo tipo de alimento estudado; a FMA apresentou coeficientes de digestibilidade inferiores às demais dietas para todos os princípios nutritivos analisados. Para a dieta FAM, os coeficientes de digestibilidade aparente dos princípios nutritivos foram maiores (P<0,05) que os coeficientes das outras dietas estudadas. Os animais que ingeriram a dieta FAM apresentaram distúrbios digestivos e baixos consumos, com efeito negativo sobre os resultados. Os coeficientes de digestibilidade aparente das demais dietas estudadas foram semelhantes (P>0,05). Os valores estimados de energia digestível (kcal ED/kg MS) e proteína digestível (%PD/MS) foram, respectivamente, para o feno de alfafa: 2285,27 e 16,04; feno das folhas de rami: 1857,88 e 16,37; feno das folhas de amoreira: 2838,48 e 15,12 e feno do terço superior da mandioca: 2155,55 e 10,57.<br>The effect of simplified diets based on forages on the apparent digestibility in white New Zealand rabbits was evaluated. The treatments were based on the following diets: reference (REF), hay of alfalfa (FAL), hay of rami leaves (FRA), hay of mulberry leaves (FAM) and hay of upper to 1/3 aereal part of cassava (FMA). The type of food affected the digestibility of the diets. The FMA diet showed low coefficients of digestibility in comparison to the other diets for all the analyzed nutrients. For the FAM diet the coefficients of apparent digestibility of the nutrients had higher values (P<0.05) than the coefficients of the other studied diets. The animals that ingested FAM diet showed digestive disorders and low consumption, with negative effect on the results. The coefficients of apparent digestibility of the remaining diets were similar (P>0.05). The estimated values of digestible energy (kcal DE/kg DM) and digestible protein (%DP/DM) were, respectively, 2285.27 and 16.04 for alfalfa hay, 1857.88 and 16.37 for hay of rami leaves, 2838.48 and 15.12 for hay of mulberry leaves and 2155.55 and 10.57 for hay of upper to 1/3 aereal part of cassava

Body mass index and complications following major gastrointestinal surgery: A prospective, international cohort study and meta-analysis

Aim Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major postoperative complications in an international cohort and to present a metaanalysis of all available prospective data. Methods This prospective, multicentre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma or formation of stoma. The primary end-point was 30-day major complications (Clavien–Dindo Grades III–V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis was used to analyse pooled results. Results This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese vs normal weight patients (13.0% vs 16.2%, respectively), but this did not reach statistical significance (P = 0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. Individual patient meta-analysis demonstrated that obese patients undergoing surgery formalignancy were at increased risk of major complications (OR 2.10, 95% CI 1.49–2.96, P < 0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46–0.75, P < 0.001) compared to normal weight patients. Conclusions In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease
