Sow condition as measured by ultrasound backfat measurements indicates that at weaning the sows average between 11 and 14 mm of backfat and enter the farrowing pens with an average backfat measurement between 14 and 16 mm. These measurements together with the outstanding reproductive performance of the sows indicates that the baleage supplemented, restricted grain feeding gestation program is meeting the nutritional needs of the sows during gestation. The farm had above average production values prior to the trial and continues to excel.

Despite the opportunity for aggression and competition for access to the baleage, little to no aggressive interactions are observed. There are approximately 70 sows to a pen with one 4 foot by 5 foot bale added to each pen every 2 to 3 days (once the previous bale has been fully consumed). The consistent resource seems to eliminates the need for aggressive interactions at any particular point in time. It also appears that full feeding of the baleage creates a sense of satiety in the sows decreasing any strong drive to eat at a specific time. This lingering sense of satiety, results in sows that are content to wait for their turn to access the baleage.

The farm conducting the trial is certified organic for all field crops. Weed pressure in the organic fields is suspected to be lowering yields at harvest. Reducing weed pressure was the initial incentive for producing a forage crop for a monogastric species. The desired outcome is that after 2 to 3 years of harvesting forage that the field will experience lower weed pressure and by extension better yields when it is returned to row crop production. The results of this component of the trial will not be available for 2 to 3 more years.

It is easy to forget how much our environment impacts our outlook.

This project provided an unexpected reminder of the immeasurable but invaluable benefits of providing animals in production more comfortable and satisfying surroundings. Yes, the sows appear more content than on other farms, and Marcel reported that the barn has been even more pleasurable to work in since they started feeding baleage.
