The study evaluated the influence of dietary levels of vegetable oil on the
performance, health status, and body linear measurements of Arbor Acre Plus
broilers. Three dietary treatments containing 0%, 1% and 2% vegetable oil inclusion
was designated as D1, D2 and D3, respectively in the basal diet. The experiment was
then mapped out using completely randomised design (CRD) with 4 replications of
10 birds per replicate. Results showed that the total weight, the weight gain and the
total feed intake in diets 3 and 2 (2197.48g/bird and 2149.29g/bird, 2155.71g/bird and
2108.00g/bird and 3041.98g/bird and 3141.98g/bird respectively) showed no
significant (P>0.05) differences but were significantly (P<0.05) different from diet one
(1) which recorded values of 2015.87g/bird, 1973.43g/bird and 3349.62g/bird. Live
weights recorded no significant (P>0.05) differences between D3 (2.13kg) and 2
(2.09kg), but were both statistically higher than D1 (2kg). The head in D3 (27.87g/kg
BW) was significantly (P<0.05) influenced when compared to the value in D2
(24.39g/kg BW), with the lowest value being recorded in D1 (23.97g/kg BW). Also,
white blood cell, red blood cell and creatinine recorded in D3 showed significant
(P<0.05) higher value in comparison to other dietary treatments with values of 5.80
x109/l, 1.88 x 106/l and 25.47Mmol/L, respectively. In terms of body linear
measurements, body weight, thigh length, body length, and height at withers were
significantly (P<0.05) different with D3 recording (P<0.05) higher values of 2.20kg,
15.82cm, 25.00cm and 27.39cm, respectively, compared to the other dietary
treatments. The average price realised, average price gain and net profit per bird
were recorded in D3, with values of N3672, N1614, and N40.36, respectively, which
were economically higher when compared to the other diets evaluated in the study.
D3 (9.20%) showed a significant (P>0.05) better % cost reduction compared to other
dietary treatments. It was therefore concluded that the inclusion of vegetable oil at
2% in D3 significantly influenced the performance, health, and body linear measurements of the broiler chickens without any detrimental effect.
