8/13/2023 0 Comments Hay round bale feederIf it had been first cutting hay stored outside there would doubtless have been much more sorting and refusal, leading to much higher waste. Consequently, cows were less able to sort through the hay to select preferred parts, and all hay was kept in excellent condition. First, the hay was second cutting, and it was stored in a barn. Results of hay waste and intake are in table 1.Īll values for hay waste were relatively low, and the authors identified some reasons. Within the space used, it contained 19 feeding spaces. It had bars set at 50 degrees every 16 inches. Trailer Feeder was 20 feet long by 7 feet wide, but hay was placed in only 12 feet of length. ![]() Vertical bars were spaced about 8 inches on all sides of the cradle, thus cows could not put their heads inside the feeder. Cradle Feeder was 12 feet long by 6 feet wide.An interior cone of bars kept the bale in the center of the feeder. Bottom and top sections were solid, with open feed access in the middle 2 feet of height. Cone Feeder was same diameter and feeder space bars as ring feeder.Solid material made up the first 2 feet of height. Round bale ring feeder, which was 7.5 feet in diameter with 18 feeder spaces separated with bars at a 70 degree angle 14 inches apart.Behavior observations included entrance to the feeder and movements that resulted in cows being displaced from the feeder.Hay intake was calculated from hay disappearance minus hay waste. Measurements of hay fed and hay wasted were taken during two 7-day periods.Hay was put into feeders when cows would likely run out the next day.Feeder space allowed was 15 inches of linear distance per head.Feeders were placed on concrete pads to facilitate collecting wasted hay. Pregnant beef cows averaging 1350 pounds were assigned to groups of 20 cows each that were housed in outside pens.Second-cutting hay was baled in 4 foot by 5 foot twine-wrapped bales which were stored in barns within 24 hours of baling and removed at feeding time.Specifics of their experimental methods were: ![]() Dan Buskirk and associates at Michigan State University evaluated 4 round bale feeder designs for the amount of hay that was wasted and differences in cow behavior.
