Possibilities to Combat MMA Syndrome in Sows
Keywords:
average daily gain, breastfeeding sows, estrum, MMA syndrome, pigletsAbstract
Sows treated with medicine 3 days before parturition and 4 days post farrowing with medicine premixes containing dimetridazol 1% delivered piglets with higher hybrid vigour that, during the sucking period, yielded higher growth gains; their death and morbidity rates were also lower compared to the control lot that was not fed medicine fodder. In sows treated with medicines we noted 11.0% MMA syndrome; during the 1 and the 2ⁿ heat cycles, 95.8% of the sows treated with medicine were in estrum and had to be mounted, compared to only 81.0% of the control lot: the sows in this last lot had 32.0% MMA syndrome, resulting in a high sterility rate.
