Abstract
Discarded banana is a valuable feed ingredient
for poultry feed formulations.However,
due to the presence of resistant starches, inclusion of more than 10% banana
meal in poultry rations reduces the growth performance.The objective of this study was to determine whether higher levels of
banana meal could be included in broiler diets if raw banana is cooked before
being processed into meal.Discarded
banana (Cavendish) collected at harvesting was processed into two types of
banana meals. Cooked banana meal was prepared by cooking banana at 100oC
for 15 minutes and subsequent drying. Uncooked banana meal was prepared by
drying at 800C for three days.
Giving a 2 x 4 factorial arrangement, 144 broiler chicks in 48 cages received
one of the eight experimental diets containing either cooked or uncooked banana
meal at 0, 10, 20 or 30% ad libitum
from day 21-42.Birds fed cooked banana
meal were significantly heavier on day 28 and 35.Live weight on day 42, weight gain, feed intake or feed conversion
efficiency were not affected either by the type or level of banana meal and
their interaction.Cooked banana meal
increased the weights of the crop and liver significantly.Weight of the small intestine, proventriculus, gizzard abdominal fat pad
and the fat free tibia ash contents were not affected by the dietary treatments.It was concluded that uncooked banana meal produced using peeled raw
banana can be included up to 30% in nutritionally balanced broiler finisher
diets without any adverse effects on performance.
