The effect of graded levels of toasted Adenanthera pavonina
seed meal (TAPSM) on the performance, carcass and organ characteristics of
finisher broiler chickens was investigated in a five-week feeding trial with
84 (5-week old) broilers divided into four groups of 21 birds per group with
three replicates of 7 birds. Four experimental diets were formulated to
contain 0, 10, 20, and 30% toasted Adenanthera pavonina seed meal
(TAPSM), represented as T1, T2, T3, and T4, respectively. Birds were
allocated to the diets in a completely randomized design and housed in a deep
litter pen with feed and water offered ad libitum. Average daily weight gain
(70.00, 72.53, 61.78 and 55.33 g), daily feed intake (170.79, 174.00, 136.00
and 100.00 g) and feed conversion ratio (2.39, 2.39, 2.20 and 1.81) decreased
significantly (P<0.05) as the level of TAPSM increased in the diets.
Dressing percent (92.37, 90.47, 89.60 and 80.56 %), breast (26.67, 22.81,
19.46 and 15.59 %), wings (10.27, 10.11, 8.15 and 7.67 %), drumstick (13.02,
12.33, 11.25 and 9.10 %), back (14.81, 13.37, 13.14 and 11.29 %) and neck
(2.49, 2.11, 2.03 and 1.89 %) decreased significantly (P<0.05) among
treatment groups. Liver (2.08, 2.42, 2.88 and 2.94 %), heart (1.09, 1.00,
1.12 and 1.58 %), kidney (1.64, 1.67, 1.86 and 1.88 %), spleen (0.31, 0.31,
0.98 and 1.20 %) and gizzard (2.24, 2.21, 2.62 and 2.63 %) weights increased
as the level of TAPSM in the diets increased, indicating that incorporating
this novel feedstuff in finisher broiler diets at levels above 10% could
reduce growth performance and decrease productivity, it is also noted that
this feedstuff could contain some anti-nutritional elements that require more
processing techniques to get to a minimal level other than toasting as
evidenced in the increasing weight of the visceral organs such as the liver
as the level of TAPSM increased in the diet. Therefore, this unconventional
feedstuff should be used with caution in broiler finisher diets and should
not exceed a 10% level of inclusion, otherwise would impair growth
performance and carcass yield.
