Performance of Soybean Meal from Different Orgins
An experiment was conducted in Korea to study the effects
of source of the soybean meal on gestation and lactation performance.
One hundred and twenty crossbred multiparous sows were assigned to three
dietary treatments and fed a corn-soybean diet containing soybean meal
from the U.S., Brazil or India as the major protein source. Diets were
formulated to meet the nutritional requirements and fed during gestation,
lactation, and from weaning to estrus according to physiological status.
The average daily gain, average daily feed intake or gain per feed intake
did not differ during the gestation period. During the lactation phase,
average daily feed intake, backfat change, and the number of days between
weaning and estrus were not different for the three treatments. The
numbers of pigs born alive and total litters weight for the sows fed
the U.S. soybean meal was significantly greater than those fed the Brazilian
meal. The performance of the sows fed the Indian sourced soybean meal
was intermediate. The sows fed the U.S. soybean meal had greater weight
loss that probably reflected litter size and greater demand on the sows.
Litter weaning weights of the U.S., Brazilian and Indian soybean meal
treatments were 56.1, 52,9 and 54.4 kg, respectively. These results
support the high quality of U.S. soybean meal.
