Effets de rations à base de déchets de mangue sur les performances pondérales et la qualité de la carcasse de porcs Korhogo en croissance au Burkina Faso

Objectif : L’objet de l’etude a ete d’evaluer les effets de l’utilisation de rations a base de provendes de mangue sur les performances de croissance et la qualite de la carcasse de porcs en croissance (25-60kg). Methodologie et resultats : Deux regimes mangue (R1 et R2) et un temoin (R3) ont ete servis a 3 lots de 8 porcs chacun. A la fin de l’essai 2 porcs /lot ont ete abattus pour apprecier la qualite des carcasses. Le GMQ de R3 (459±62g) a ete significativement superieur a ceux de R1 (399±81g) et R2 (412±81g) (P<0,05). L’IC de R3 (1,9±0.4) a ete significativement superieur a ceux IC de R1 (2,5±05) et R2 (0,6±06) (P<0,05). Les rendements carcasses de R1 (83,4%) et R2 (77,6%) ont ete plus eleves a celui de R3 (76%). Le taux de gras de R3 (32,8%) a ete plus eleve que ceux de R1 (30,7%) et R2 (31,7%). Conclusion et application : L’etude a montre l’utilisation possible des provendes de mangue en substitution au mais. Ceci ouvre des perspectives d’accroissement de la disponibilite d’aliments pour les porcs moins competitifs entre l’homme et les animaux. Les rations qui les incorporent sont propices a la production de viande maigre tres prisee par les consommateurs. Des provendes et des formules les incorporant pourront etre proposees pour l’alimentation des porcs, l’amelioration de la productivite des elevages, de la qualite des carcasses et du revenu des eleveurs. Des etudes complementaires sur la digestibilite des provendes et de meilleures formules seront necessaires pour affiner les recommandations d’utilisation aux eleveurs.

Methodology and results : Two mango diets (R1 and R2) and a control (R3) were served to 3 batches of 8 pigs each. At the end of the trial 2 pigs / lot were slaughtered to assess the quality of the carcasses. The Daily Weight Gain (DWG) of R3 (459±62g) was significantly higher than those of R1 were (399±81g) and R2 (412±81g) (p<0.05). The R3 CI (1.9±0.4) was significantly < at R1 (2.5±0.5) and R2 (2.6± 06) (p<0.05). Carcass yields of R1 (83.4%) and R2 (77.6%) were higher than that of R3 (76%). The fat content of R3 (32.8%) was higher than those of R1 were (30%) and R2 (31.7%). Conclusion and application : The study showed the possible use of mango feed to substitute maize. This opens up prospects for increasing the availability of food and thus less competition between humans and animals. It has also shown the tendency of mango diets to produce lean meat; which is very popular to consumers. Feed and food formulas incorporating mango waste may be proposed for the feeding of pigs hence improving the productivity of livestock, the quality of carcasses and the income of farmers. Further studies on a digestibility of feed and the better diets will be needed to refine the recommendations of use to breeders.
