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:
- The trial ration was comparable in price or less expensive;
- Their yield weight of milk, fat and protein increased including a daily milk increase of nearly 2 litres per cow on farm one and 3.5 litres per cow on farm two; and
- The additional canola meal allowed them to streamline sourcing protein ingredients.
These findings are important for dairy operations looking to lower feed costs while maintaining production. “The trial demonstrated that cows will readily accept 3.5 to 4 kilograms of canola meal,” stated dairy nutritionist Dr. Essi Evans of Technical Advisory Services, Inc. “It provided cows with a well-balanced diet and allowed higher-priced proteins to be removed.”
“Although the field trials were small, we are encouraged by the positive results, and will continue to research the uses of canola meal for dairy animals,” says Brittany Dyck, canola meal manager with the CCC
The United States is the largest export market for canola and canola products. In 2017, exports to the U.S. were worth $3.7 billion – including 574 thousand tonnes of seed, 1.9 million tonnes of oil and 3.4 million tonnes of meal.
