Effects of feed intake, weight gain and digestibility when
growing Red Sokoto goats consuming Aspergillus niger
treated and untreated shea-butter cake (SBC) were
determined. Twenty five Red Sokoto goats in a completely
randomized design model with 56 d periods consumed diet A
(control, without SBC), B (15% Aspergillus treated
SBC), C (15% untreated SBC), D (7.5% Aspergillus
treated SBC) and E (7.5% untreated SBC). Total DMI rose (P <
0.05) with Aspergillus treated diets (B and D) than
the untreated diets (C and E). The trend was similar for the
rest of the variables (CPI and EEI) except for the crude
fibre intake which did not show a specific trend. Dry matter
digestibility for the control diet (A) was the lowest than
any of the other diets while the highest dry matter
digestibility was recorded for diet D. For the untreated SBC
diets (C and E) versus Aspergillus treated diets (B
and D), crude fibre digestibility, crude protein
digestibility and ether extract digestibility were lower for
the untreated diets C and E. Liveweight gain was greatest (P
< 0.05) for the control diet (A), greater (P < 0.05) for
Aspergillus treated diets (B and D) than for the
untreated diets (C and E) and tended to be (P < 0.05) great
for 15% fungus untreated SBC than for diet E (7.5% fungus
untreated SBC). Up to 15% of complete diet for Red Sokoto
goats can be composed of Aspergillus treated SBC with
little or no reduction in feed intake, weight gain or
digestibility coefficient.
