Dietary nutrient management: What goes in, must come out.,[object Object],Dr. Katharine Knowlton, Dep’t of Dairy Science, Virginia Tech,[object Object],Jimmy Huffard, Huffard Dairy Farm, Crockett VA,[object Object]
Nutrient concentration,[object Object],Specialization,[object Object],Nutrient Importation,[object Object],Nutrient Concentration,[object Object],Ground and Surface Water,[object Object]
Sources of nutrients,[object Object],Smith & Alexander, 2000,[object Object]
Soil P accumulation,[object Object],Phosphorus,[object Object],Manure N and P in imbalance,[object Object],Manure application to meet N needs = excess P,[object Object],P accumulates,[object Object],P can runoff from saturated soil, even without erosion,[object Object],Contaminates surface water,[object Object],Soil test P in Rockingham county, VA, ‘07-10,[object Object]
Does diet matter?,[object Object]
P intake and excretion,[object Object],Relationship between P intake and excretion?,[object Object],13 early-lactation cows,[object Object],Fed diets containing one of 3 levels of dietary P,[object Object],Days 7-75 of lactation,[object Object],Total collection study (milk, urine, feces),[object Object],Direct, linear relationship between P intake and excretion,[object Object],Knowlton et al., 2002,[object Object]
Why overfeed?,[object Object],Uncertainty about requirements - What’s the “bare minimum”?,[object Object],Marketing,[object Object],Link to reproduction?,[object Object],Bad habits,[object Object],Undetected variation in feed P, “problem feeds”,[object Object]
Phosphorus,[object Object],Dietary requirement,[object Object]
Survey says???,[object Object],Survey of dairy nutritionists across US,[object Object],Independent & company affiliated,[object Object],131 respondents,[object Object],Range from 1 client to 150,[object Object],From 200 cows to 95,000,[object Object]
“Energy balance is more critical to reproductive success than "over-loading" P to replace heat detection management. “,[object Object],53% say ‘yes, a priority’,[object Object],“Clients are being regulated with nutrient management plans, so it is a priority, but ration cost dictates the use of higher levels of byproduct feed that contain more P.”,[object Object],“I work close to the Bay, so I constantly monitor the P levels in my diets.”,[object Object],“P requirements are met or exceeded by natural sources in almost all cases. We do not address excesses unless nutrient management plans dictate.”,[object Object]
“Slightly high”,[object Object],“Only a tad low”,[object Object],“I feed at NRC recommendations and production, health and reproduction among the 25,000 cows I serve is excellent.”,[object Object],“I am very confident that the 0,31% P requirement was well researched. Dr. Larry Satter's group at USDA Dairy Forage center did good work looking at bone strength with 0.31 P diets in lactating first calf heifers, the class of animal with the greatest P requirements.”,[object Object],“Most of the problem is with availability data”,[object Object],“Why is Germany's bioavailability correct at 80% when the 1989 NRC used a lower figure?”,[object Object]
“(Our company) has recommended lower P levels for years and I always try to keep at the low end.”,[object Object],“The mindset of vets and educators has changed allowing us to run lower P levels.”,[object Object],“I reduced my recommendations because of manure management concerns and how feeding management can impact P levels in manure.”,[object Object],“Public perceptions of animal agriculture & CAFO's may prevent future expansion of many dairy farms. If we’re not proactive , we’ll be seen as "hiding" poor practices.”,[object Object],“I changed because of research showing we did not need to supplement as much.”,[object Object]
Precision Phosphorus Feeding for Virginia Dairy Farms,[object Object]
Components,[object Object],Feed sampling, analysis, bimonthly 3 years,[object Object],Calculate P requirements, P intake,[object Object],Incentive payments based on ( intake / req’t ),[object Object],$12 /  $6 / $3 per cow per year,[object Object],Payment capped at 400 cows,[object Object],No penalty for overfeeding,[object Object]
Did it work?,[object Object],215 herds,[object Object],Each year, more farms succeeded in reducing dietary P to receive incentive payment,[object Object],P feeding down by ~5-15%,[object Object],Next steps?,[object Object]
Survey says???,[object Object],Survey of dairy nutritionists across US,[object Object],Independent & company affiliated,[object Object],131 respondents,[object Object],Range from 1 client to 150,[object Object],From 200 cows to 95,000,[object Object]
The most challenging aspect of reducing dietary P?,[object Object],“I sample, so content is not a worry. The biggest problem is that low cost byproducts like DDG have too much P.”,[object Object],“Price is easy - the problem is trusting the P value on Soy, DD, Wheat, Brew etc.”,[object Object],“P availability????”,[object Object],“Sometimes higher P feeds, like distillers dried grains, are cost effective feeds.   Hence, overfeeding P may be more economical than keeping P at NRC 2001 levels.”,[object Object],“We need new research considering the availability of organic P.”,[object Object]
What new information do you need?,[object Object],What about new and well designed research?,[object Object],“Not all software programs are "current" and I question myself on how low is too low.”,[object Object],“I think current NRC recommendations are adequate. The biggest thing is making sure our feedstuffs have the true amounts and that they are available to the animals.”,[object Object],Need to work on true bioavailability of P in feedstuffs,[object Object],Adequate data and field experience exist. Train people. Or do a P tax like Netherlands.,[object Object]
The distillers grain challenge,[object Object]
Organic P availability?,[object Object],Endogenous phytase activity is affected by diet.,[object Object],Phytate escape from rumen,[object Object],Heat treated grains,[object Object],High rate of passage,[object Object],High organic P,[object Object],Yanke et al., 1998,[object Object]
Precision Feeding of Phosphorus for Dairy Farms- Katharine Knowlton
“If it was easy, everyone would do it.”,[object Object]
Virginia regulations,[object Object],Virginia Pollution Abatement permit,[object Object],CAFO is > 300 animal units, liquid manure storage,[object Object],P-based nutrient mgmt planning since 2007,[object Object],Storage required, no discharge to surface water,[object Object],120-150 days manure storage ,[object Object],Annual inspections of permitted facilities,[object Object]
Precision Feeding of Phosphorus for Dairy Farms- Katharine Knowlton

Farm in the family for >200 years,[object Object],Jerseys arrived in 1929,[object Object],350 milking cows, plus 360 heifers,[object Object],Milk 2X,[object Object]
Huffard dairy,[object Object],General manure & crop management,[object Object],Impact of dietary changes on manure P,[object Object],Outlook for future, concerns and opportunities,[object Object]
