ABSTRACT
This study was conducted to
evaluate the effect of raw Jackfruit seed meal (JSM) partially replacing
soybean in broiler chickens diet. A total number of 150 broiler chickens were
used for the experiment which lasted for 49 days (7 weeks). The experiment was
carried out at the Poultry Unit of the Teaching and Research Farm of Michael
Okpara University of Agriculture, Umudike. The experimental birds were divided
into four treatment groups denoted as T1, T2, T3and T4 containing 0%, 10%, 20%
and 30% JSM respectively. Each treatment group was replicated thrice and each
replicate contained at least 12 birds arranged in a Completely Randomized
Design (CRD). Data were collected on proximate composition of experimental
diet, growth performance (initial weight, final weight, daily feed intake,
daily weight gain, Feed Conversion Ratio), carcass characteristics and internal
organ proportions. All data collected- were analyzed statistically using SPSS
Software Package. The dry matter and the ash increased as the level of the JSM
increased in the diet. The CP and ash content of the JSM diets T2, T3and T4are
higher (P<0.05) than that of the Control diet in the starter phase. Crude protein was similarly highest (P><0.05) in T1, T2and T3(19.6%, 19.1% and 18.40%) but declined significantly (P><0.05) in T4 (15.0%). The result of growth performance shows that the 10% and 20% JSM diets compared with the Control diet in final weight and DFI, whereas, the 30% JSM depressed final weight (980.95g/bird) and DFI (82.84g/bird). Daily weight gain and FCR were not affected significantly (P>0.05).
The inclusion of JSM significantly (P<0.05) affected the live weight, de-feathered weight, dressed percent, thigh, drumstick, back and breast but did not significantly (P>0.05)
affect the dressed weight and wings. The reduction in live weight, de-feathered
weight, thigh and drumstick at the 30% JSM may be connected with
anti-nutritional factors. A numerical assessment of the dressed weight shows
that the Control diet performed better than the JSM containing diets and that
T3(20% J SM) which recorded 91 6.66g performed very close to the Control diet
which recorded 1008.33g. The internal organs showed significant differences in
small intestine and large intestine lengths. The small intestine length was
highest in T3 (205.33cm) and may be connected with efficient absorption. Large
intestine length decreased at 30% JSM (17.83cm) compared to 28.66cm, 28.00cm
and 3 1.00cm respectively in T1, T2and T3 and the reduction may be connected
with anti-nutritional factors. In conclusion, T3containing 20% JSM recorded the
highest final weight, higher live weight, de-feathered weight and dressed
weight compared to the 30% and 10% JSM level and highest small intestine length
which enhanced higher absorption rate. The 30% level depressed performance in
terms of lowest final weight, lowest live weight, drumstick, thigh weight and
shorter small intestine length. The 20% of JSM is thus recommended as the best
level to replace soybean in broiler chickens diet.
