ABSTRACT: The study evaluated the
growth performance and carcass quality of COBB500 broilers fed two experimental
rations incorporating feed and mango fine ED10 for a batch of 83
birds, ED20 (batch of 83 birds) in comparison with a commercial
control ration CCD (84 birds). For this purpose, 250 day-old chicks of this
breed were purchased in Korhogo and transported to Tengréla in Ivory Coast for
rearing. The results show that substituting mango provender ans and mango seed
flour for maize resulted in rations with costs per kgMS of 215.35FCFA,
2016.93FCFA and 320FCFA for the ED10, ED20 and CCD rations respectively. The production costs
per kg of chicken (FCPkgLW) of the CCD ration were significantly higher
than those of the ED10 and ED20 (p 0.05). ADGs were significantly different and
decreasing from CCD, ED20 to ED10 (p 0.05). Average weights at 42nd day for ED20 and CCD were homogeneous (p > 0.05) and
significantly higher than for ED10 (p 0.05). By day 49th the average weight of ED20 had reached and exceeded that of CCD by day 42nd. PSLW, HCW and CCW were significantly
different and decreasing from CCW, ED20 to ED10 (p 0.05). Average hot (HCY) and cooled (CCY) carcass
yields of ED20 and CCD rations were comparable (p > 0.05) and significantly higher than those of ED10 ration (p = 0.009) and 0.003). Average drumstick and neck
weights were significantly higher and lower for CCD, ED20 and ED10 (p 0.05). For all other parts of the cut, the average
weights of the CCD ration were significantly higher (p 0.05) than those of the ED20 and ED10 rations, which were homogeneous (p 0.05). The incorporation of mango provender and mango seed flour in broiler rations
offers the prospect of reduced production costs, less competition between man
and animals over cereals, and lean meat production that is more appreciated
than that of chickens fed conventional feed. As it stands, the ED20 ration can be recommended as a growth diet for broilers. It would be necessary
to determine the levels of anti-nutritional substances in mango feeds and to
assess the in vivo digestibility of mango ingredients and the diets
incorporating them.
