Abstract
A total of 96 crossbred barrows and gilts (initial BW of 9.12 kg; age 4 wk) were used
in a 28-d experiment to compare growth performance and nutrient digestibility for
pearl millet-soybean meal and corn-soybean meal diets. Dietary treatments were arranged
in a 2 × 3 factorial of corn-soybean meal control, 50 and 100% pearl millet grain
replacement for corn. The diets were formulated on an equal calorie and nitrogen basis.
Final body weight was unaffected (P>0.05) by dietary treatment. Body weight gain during the 28-d experiment also was
unaffected (P>0.05) by dietary treatment. Increasing the level of pearl millet in the diet had
no effect (P>0.05) on feed intake or gain:feed ratio. During the 28-d experiment, male pigs consumed
more (P<0.04) feed than females; however, female pigs had higher (P<0.04) gain:feed ratio than males. Dry matter, nitrogen, and ash digestibility were
unaffected (P<0.05) by treatment. The addition of increasing levels of pearl millet tended to decrease
(P<0.10) ether extract digestibility but DE digestibility was not affected (P<0.05). Results from this study demonstrated that pearl millet-soybean meal diets,
balanced on isocaloric and isonitrogenous basis, can be used as a satisfactory replacement
for corn-soybean meal diets for nursery pigs.
