Performance, Organ Weight Dynamics and Economics of Production of Laying Hens Fed Increasing Levels of Moringa oleifera Leaf Meal.

Abstract

Twelve weeks feeding trial was carried out to investigate the effect of increasing levels of Moringa oleifera leaf meal (MOLM) on the performance, organ weight characteristics and economics of production of laying hens. 160 Harco layers at 5-6 weeks of laying life were divided into 4 groups of 40 layers each and each group replicated four times comprising of 10 birds each. Four diets were formulated such that Diet 1 contained no MOLM, while Diets 2, 3, and 4 contained MOLM at 5.0%, 7.5%, and 10%, respectively. Each group was randomly assigned to one of the four diets in a completely randomized design. Result showed that layers on diet 1 (0%) and 3 (7.5%) had significantly higher (P<0.05) body weight change. Also, birds on diets 3 (7.5%) and 4 (10%) recorded higher (P<0.05) daily feed intake. The control group had significantly (P<0.05) least Hen Day Production and superior feed conversion ratio. There were no significant differences (P>0.05) in the weights of the internal organs except a significant reduction of abdominal fat observed in Diet2 (5.0%). The control group recorded the highest cost of feed per kg egg. Diet 4 (10%) recorded the best cost per kg feed (N/kg) N124.00 and the best cost of feed per kg of eggs; N271.56. These decreased with increased level of MOLM inclusion thereby reducing the total cost of production. In conclusion, Moringa oleifera leaf meal could be included into layers diets up to 10% level without any deleterious effects.
