Abstract
This study was carried out in Central Tanzania and aimed at evaluating the effect of Baobab
seed cake (BSC) on growth performance and carcass quality of pigs. Twenty-four (24) weaners
of both sexes were involved in the study which lasted for 84 days. Four diets were formulated
with BSC replacing sunflower seed cake at four levels of 0, 7, 14 and 21% and allotted to four
dietary treatments T1, T2, T3 and T4 respectively, in a completely randomized design. Results
showed that the four levels of replacement had no significant effect on body weight gains although
T2 outperformed the others in terms of weight gain with 23.19kg whereby T1 (20.54kg) and T3
(20.21kg) had almost similar weights and T4 had the lowest weight gain (15.52kg). The cost of
production, carcass weights, and dressing percentages varied significantly (P≤ 0.05) whereby costs
of production (in Tshs) were 151,643.28, 162,965.52, 150,820.03 and 117,646.74 for T1, T2, T3
and T4 respectively. Carcass weight and dressing percentages were 23kg, 20.5kg, 18.50kg, 9.50kgs
and 55.4, 53.9, 51.4 and 48.7% for T1, T2, T3 and T4 respectively. Histopathology analyses of the
carcasses indicated that there were no any detrimental changes resulting from an inclusion of BSC
in pig diets thus the pork was fit for human consumption.
