mixer wagon, ration quality control
Alternative methods of sequencing ration ingredients into a mixer wagon were evaluated using a 13.53% roughage finishing diet. Batches A and B evaluated the addition of grass hay to a triple auger mixer either last or first, respectively. Batches C and D examined adding liquid supplement to a reel type mixer either immediately after the addition of corn or first, respectively. Three samples were obtained from each batch after 2, 4, 6 and 8 minutes. The coefficient of variation among acid detergent fiber levels at each time period for each batch was used as the criterion for determining adequacy of mix. Both batches A and B appeared adequately mixed after 6 minutes, indicating that ground grass hay could be added to a finishing diet either first or last when using a triple auger mixer. Batch C appeared adequately mixed after 4 minutes. Coefficients of variation for all mixing times were larger for batch D as compared to batch C at all mixing times, indicating that adding liquid supplement to the batch first may result in a poorer ration mix than adding liquid supplement immediately after corn.
