Key findings included:
- The treatment group receiving the DDG supplementation in the strip-grazed system maintained their body-condition score of 5.7 even with three ice events that impacted feed availability for 12 of the 49 days. During this same period, the BCS of the control cows decreased from a beginning score of 5.7 to 5.4.
- The DDG-supplemented system provided an economic advantage of $18.82 per head over the continuous-grazed control group. This difference compares the DDG and hay supplementation costs of the treatment group to the control group’s actual hay and estimated DDG cost to increase the control cows’ BCS by 0.3 points.
- Non-fenced corn fields can be successfully grazed by utilizing electric fences. Through this effort, cow-calf producers can more efficiently utilize their feed resources, reduce winter stored-feed costs and maintain cow body condition through a variety of weather conditions.
