Growth Performance of Broilers fed Moringa oleifera Supplemented Feed and Challenged with a very virulent Infectious Bursal Disease Virus

Abstract

A study was conducted to assess the growth performance of broiler chickens fed Moringa oleifera leaf (MOL) feed supplement
and challenged with a very virulent infectious bursal disease virus (vvIBDV). Two hundred and forty day-old Ross 308 hybrid
broiler chicks were randomly assigned into groups A, B, C and D of 60 chicks each and were raised in deep litter housing.
Broiler starter (BS) and broiler finisher (BF) mash were formulated each with 5% MOL included as part of the feed ingredient
for broilers in groups A and B while BS and BF for broilers in groups C and D were formulated without MOL. Broiler chickens
in groups A, B and C were challenged at 35 days of age with 0.05 ml of a live vvIBDV, while those in group D served as
control. Daily feed intake (DFI), feed conversion ratio (FCR) and average body weight gain (ABWG) was used to assess the
growth performance. At 42 and 49 days of age, significant difference was observed in the feed intake of broilers in groups A,
B and C when compared with group D (p = 0.0001). At 49 days of age, broilers in group A and D significantly (p = 0.0001)
added more weight than those in groups B and C respectively. Broilers in group B had a significantly (p = 0.0006) lower FCR
than those in group A, C and D at 28, 35 and 42 days of age. Despite the challenge with vvIBDV, MOL inclusion in the diet of
broiler chickens resulted in reduced DFI, good FCR, increased ABWG and final body weight and carcass weight.
