Title: Canola as a feed for dairy cows


1
Canola as a feed for dairy cows
2
Canola defined
  • The official definition of canola is a rape plant
    of an imporved variety having seeds that are low
    in erucic acid and are the source of canola oil

3
Word origin of canola
  • The word origin of canola is
  • CAN Canada
  • O Oil
  • LA Low Acid

4
Facts about Canola
  • Canola is Canadas major oilseed crop
  • Canola averages 0.6 erucic acid
  • Considered a very healthy oil that may improve
    health by lowering blood cholesterol levels and
    regulating blood flow
  • Good source of vitamin E

5
Canola as a feed additive
  • Feeding dairy cows is the highest cost on a farm,
    the use of high quality forages and corn silage
    control these costs. If a poor growing season
    occurs levels of protein and energy will decrease
    in our harvested feeds, lowering feed intakes and
    milk production. In this case farmers must
    purchase feed additives to raise protein and
    energy levels.

6
Canola as a feed additive
  • Canola is grown for its oil, the meal, a
    byproduct remaining after the oil is pressed from
    the seed, is used as a protein supplement.
  • The nutritional value of canola meal compares
    favorably to soybean meal, being just slightly
    lower in protein and energy but higher in fiber.

7
Canola as a feed additive
  • Research has demonstrated its value as a very
    satisfactory protein and mineral source for all
    classes of dairy animals.
  • Canola meal protein is degraded relatively fast
    in the rumen.
  • Canola meal is much safer to feed than rapeseed
    meal.

8
Canola meal-vs-Soybean meal
  • Canola meal Soybean meal
  • 40 crude protein - 49.9 crude protein
  • 3.0 fat - 1.5 fat
  • .79 NEl - .89 NEl
  • 36 NDF - 15 NDF
  • The added fiber will promote a healthy rumen and
    the levels of crude protein are adequate for a
    healthy dairy cow supplement.

Canola Meal
  • Canola meal has an excellent amino acid profile
    and is rich in vitamins and essential minerals
  • Canola meal is one of the most widely used
    protein sources in animal feeds.

11
Research study done in Alaska
  • The study done was called Use of Canola in dairy
    cattle diets from the Agriculture and Forestry
    Experimentation Station by
  • Kirsten Randall
  • Stephen M. Dofing
  • Donald J. Brainard

12
Research Study
  • The study was done over 3 years, 20 cows were
    housed in 5 groups of 4 cows each.
  • Cows began the trial in their 3rd week post
    partum and continued through their 15th week.
  • Diets contained 0,2,4,6 pounds of canola/cow/day,
    which equals to 0,4,8, and 12 total canola in
    the diet.

13
Results of the tests showed
  • Results of the tests showed more milk production
    in the diets that contained canola as a feed
    additive over the non canola test group.
  • The group fed no canola averaged 91.6lbs of
    milk-vs-103.2lbs. for the group fed 2 lbs. of
    canola.
  • Researchers recommended feeding canola at a rate
    of 3-4lbs/cow/day or 6-8 of the total diet on a
    dry matter basis.

14
Price of Canloa-vs-Soybean meal
  • Canola Meal
  • 159.00/ton
  • On a 100 cow farm at the recommended rate of 2-3
    pounds/cow this would be 0.24/cow/day.
  • Soybean Meal
  • 190.00/ton
  • 100 cow farm at 2-3 pounds would be 0.28/cow/day

15
Conclusion
  • Overall the benefits of using canola will help
    our dairy cows by increasing protein, fat, and
    fiber levels.
  • Contrary to what is said canola is safe for cows
    and has low levels of erucic acid.
  • The biggest advantage is that it is palatable and
    highly digestible.
