How To Make Meal From A Non-Food Oilseed Into A Food?

A Few Challenges To Feeding Carinata Meal

Glucosinolates Are Goitrogenic

• Depressed thyroid function

– T3 – T4

• Erucic acid

– myocardial lipidosis – fatty heart

Intake Of Brassica-based Meals Are Regulated

• AAFCO & FDA limits intake of brassica meals to ruminants

– Previously marketed in US as ‘Mustard Meal’ (IFN 5-12-149)

• 10% DM in diets of nonlactating ruminants
• 0% DM in nonruminant and lactating cattle diets

– Brassica carinata meal has been recommended by FDA for definition in 2017 AAFCO by IDC

• T71.35

Intake Of Brassica-based Meals Are Regulated

• Proposed definition of Brassica carinata meal.
• T71.35 Brassica carinata meal, solvent extracted is the meal obtained after the

removal of most of the oil by solvent extraction of Brassica carinata seeds. The meal shall contain less than 2% erucic acid and less than 30 micromoles of total glucosinolates per gram. It is a source of protein for beef cattle in an amount not to exceed 10% of the total diet. The maximum sulfur content must be guaranteed.

• Predominate concern related to erucic acid intake in humans

– Myocardial lipidosis

Beef Feeding Trials At SDSU

• Why are cattle fed protein meals?

– After puberty performance in cattle is limited by energy – Ruminal fermentation can be limited by N to support optimal microbial growth

• Protein meals are often fed to optimize ruminal fermentation

– to yield more energy from fermentation

Beef Feeding Trials At SDSU

• In Vitro

– estimate nutrients that are ruminally available

• Cow performance and digestion

– determine value to cow-calf producers as a protein supplement

• Feeding behavior in finishing cattle

– evaluate value of carinata meal to finishing cattle

In Vitro Experiments

• Modified Tilley and Terry procedure to estimate potential nutrient

digestion from several oilseed meals produced from different manufacturing methods

– Incubation of feed in ruminal fluid & then acid-pepsin solution – Method is correlated to amount of nutrient disappearance from forage

Rate Of Nutrient Disappearance From Brassicas

• Ruminal fermentation is dynamic

– Ruminally available N = a + b × (1- e-kd × t) – Ruminal release and degradation of Gls could be related to amount of time feed remains in rumen for fermentation

What Did We Learn?

• Estimates of total-tract digestion indicate that Carinata meal may

be extensively digested

• Carinata meal appears to be a good source of ruminally

available nitrogen

• Carinata meal in our study contained detectable amounts of

goitrogenic glucosinolates but amounts decreased with increased amounts of time

Effect Of Solvent- Or Mechanically-extracted Brassica Carinata Meal On Performance Of Cows

• What are effects of extraction method on value of carinata meal

to cows?

• Does value of carinata meal differ when cattle are fed forage-

based diets with different particle size?

Methods

• 56 non-pregnant cows were blocked by BW
• Fed either long-stem or chopped corn-stalk residues
• 2 cows within each pen randomly assigned to receive:

– Cold-pressed carinata meal – Solvent-extracted carinata meal – Canola meal (positive control)

• 1 cow within each pen was randomly assigned to receive no

supplemental protein (negative control)

Observations

• Differences in response to supplemental protein and particle size
• No protein source × particle size of corn stalk residues

– Apparently, greater forage length does not provide added benefit to supplementing cattle with carinata meal

• As expected corn stalk residues did not supply adequate protein

to optimize cow performance

• The positive control ameliorated limits in protein
• Solvent extracted carinata meal enhanced cow performance

similar to the positive control

• Apparently cattle will voluntarily consume only modest amounts
• f ME-carinata when fed as the entire meal
