Background: The aim is to compare the effectiveness of 3% of natural preparations mixtures based on kaolin associated with garlic, ginger and/or their mixture on the performance, the cutting yield, carcass and bone qualities of broiler.
Methods: 192 one-day-old Cobb 500 chicks were assigned to 04 groups of 48 four-replicate chicks (C: without addition; Kgar: 3% kaolin-garlic; Kgin: 3% kaolin-ginger and Kgg: 3% kaolin-garlic-ginger).
Result: Results showed that the mixtures significantly improve body weight and feed efficiency at 42 days, with nonetheless a more marked effect for the Kgar group (BW: +4.5%; FCR: -5.5%). In addition, still in favor of the Kgar group, the same tendency was recorded for the yield of chicken ready-to-cook (+3.2%; P=0.02) accompanied by enhanced breast and thighs yields. In terms of quality, the mixtures significantly impacted the meat conservation criteria by reducing water-holding capacity by almost 50% and less abdominal fat deposition. Finally, although not significant, the indicators of bone quality measured (ash content and seedor index) appear better in chickens receiving mixtures. The results of this study show the interest of adding a mixture of kaolin and condiments in improving broiler performance, meat quality and bone characteristics.
RESUMELes ressources génétiques caprines (Capra hircus L.) d'Algérie n'ont pas fait l'objet d'une attention particulière comparativement au reste des populations de l'espèce du Bassin méditerranéen. En témoigne la méconnaissance de leur degré d'appartenance à l'une des trois catégories de la classification évolutive des animaux de ferme qui comprend espèce sauvage, population primaire - initialement population traditionnelle - et race standardisée. Des données relatives à la variabilité génétique de douze loci à effets visibles sont considérées pour caractériser les populations caprines des Monts Dahra et Aurès. Ces travaux se basent sur l'emploi de deux indices récemment introduits: l'indice de primarité loci en ségrégation (IPs) et l'indice de primarité allèles au locus Agouti (IPa). Les résultats obtenus plaident en faveur de l'appartenance de ces populations à la catégorie de population primaire.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
