Canola meal continues to demonstrate its value for dairy producers, with on-farm trials resulting in 2 to 3.5 more litres of milk per cow per day. According to Gordon Speirs, a dairy manager at Shiloh Dairy in Wisconsin, using canola meal is a “no-brainer.” After participating in a recent on-farm trial where canola meal was fed at high inclusion rates, Speirs said, “Canola contributes to cost-efficient production. We no longer have to source and store expeller soybean meal.”
The Canola Council of Canada (CCC) conducted the on-farm trial with the help of GPS Dairy Consulting, group of independent dairy nutritionists in Wisconsin. The purpose of the trial was to determine whether producers could increase efficiency by replacing multiple high-priced protein sources, such as animal protein blends and treated soybean meal, with canola meal while maintaining milk yield.
Two Wisconsin dairies volunteered to participate in the trial. The first farm, Shiloh Dairy, milked 2,100 cows with an average of 45 kilograms of milk per cow per day. The second farm was a 700-cow dairy that also averaged 45 kilograms of milk per cow per day. The trial rations replaced animal protein and high-bypass soybean meal with canola meal and rumen-protected lysine. Cows were monitored for a total of four months: two months on the control diet and two months on the trial diet.
After the trial was complete, both dairies noted:
