Effect of a liquid extract of Moringa oleifera on body weight gain and overall body weight of weaning pigs

Weaning piglets were continuously delivered a fermented extract of Moringa oleifera at a dilution of 1/250 in the drinking water beginning at 21 or 28 days of age. Weekly body weight and weight gain were measured for 5 consecutive weeks in the fermented extract treated and the control group. There was no significant difference between those groups (P<0.05), except the body weight gain in the period 21-28 days...
