Avocado/Soybean Unsaponifiables (ASU)
- Extract of the oils
- Inhibits inflammation
- Complements effects of glucosamine and chondroitin. (1+1+1= >3)
- Adding ASU decreases the amount of chondroitin needed - less $p.2 -

So what’s it do?
- ASU supports cartilage matrix production and helps protect against cartilage damage
- Safety demonstrated
- Dasuquin efficacy may be similar to NSAIDs in dogs (for joint problems)p.3 -

ASU - Canine Cruciate Model
- Surgical Model of Cr Dx
- 16 cross bred (20-25 kg)
- 8 placebo
- 8 Tx 10 mg/kg Daily
- Transect the cruciate
- 8 wks - examine joints
- Gross/Histological
- Fewer osteophytes
- Thicker cartilage
- More normal chondrocyte morphology

DISCUSSION/CONCLUSION:
We demonstrated that the combination of ASU, Glu, and CS profoundly pressed pro-inflammatory gene expression in chondrocytes, fibroblasts and monocyte/macrophages. The combination treatment was effective in reducing the expression of chemokines, cytokines, and mediators of the arachidonic and nitric oxide pathways (COX-2 and iNOS). Our results reinforce the potential clinical utility of the combination of ASU, Glu, and CS in the management of inflammatory disorders, providing an alternative option to patients who fail to respond to the single agents alone.

Fish oil intake in the 4 studies
- If a 20 kg dog ate 250 g a day
- Rousch, JAVMA, 2009 - 84-110 mg/kg
- Morneau, JAPAN, 2010 - 101 mg/kg
- Fritsch, JVIM, 2010 - 3 diets - 100-375 mg/kg
- Hielm-Bjorkman - 110 mg/kg
- How much is too much?
- NRC - suggests around 375mg/kg
- Possible clotting abnormalities
- Immune Suppression?
- Vitamin E supplementation?p.26 -

Math!
- 100lb dog (50kg)
- DJD - 80-120mg/kg/DAY Omega-3
- 50 x 100 = 5000
- Equals =
- 3 pumps of Welactin 2x day NOTE BID
- 3 cups of Hill’s J/D twice a day
- Up to 25 Omega-3 capsules twice a day!
- If they have what they are supposed to havep.27 -
