1 Trends in Feed and Manure Phosphorus John Peters Soil Science Department UW-Madison
2 Acknowledgments Laboratory manure and TMR data provided by: Dairyland Laboratories, Inc. Rock River Laboratory, Inc. Digester/separator data provided by Gordondale Farms, Nelsonville, WI Dairy dietary P information provided by Mark Powell, USDA-ARS
3 Phosphorus story More than half of Wisconsin dairy farmers feed more P than cows need According to National Research Council recommendations Source: Powell et al., 2002 survey of 93 farms.
4 How much P is being fed? NRC 1989 What dairy producers fed (1999) Beginning Signs of P Deficiency NRC 2001 What dairy producers feed (today) Dietary Phosphorus (% DM)
5 Potential annual phosphorus inputs and outputs from a 100 cow Wisconsin dairy farm P inputs P outputs (lb) (lb) Protein supplement 1219 Milk 1806 Dicalcium phosphate 1627 Cull cows/calves 300 Grain 0 Surplus Feed 0 Forage 0 Manure 0 Fertilizer 1181 Runoff 201 TOTALS 4027 TOTALS 2307 Farm P balance = +1,720 lb P
6 Phosphorus (P) story
7 Average soil P levels of Wisconsin cropland fields over time
8 Why is P overfed? Myth that increasing P improves reproductive performance Little research on the absolute minimum P content required to support moderate to high levels of milk production Aggressive marketing of P supplements Cheap and available protein feed sources that are high in P content
9 Debunking the myth: Milk production is not harmed by lower P diets Summary of 8 studies Milk Production (lbs/day) Studies Low dietary P High dietary P
10 National Research Council (NRC) feed-p recommendations Milk Production Dietary P Level (lbs/day) (%) Adapted from Nutrient Requirements for Dairy Cattle, Seventh Revised Edition, National Academy Press Washington, D.C., January 2001
11 New Assessment Tool: TMR Sample

19 Dietary P conclusions Performance (reproductive efficiency and milk production) is not adversely affected by reducing P to NRC recommendations Recent TMR tests indicate a trend toward reduced P levels in dairy rations

21 Effect of P intake on P in manure Fecal P, lb/cow/year % P in diet Increasing P content from 0.35% to 0.55% of diet dry matter increases P output from 42 to 78 lbs/cow/year!
22 Effect of P intake on form of P in manure Dietary P intake, % soluble P insoluble P A high P diet produces manure that is more likely to cause environmental problems.
23 Land required for recycling fecal P from one cow fed various dietary P levels Acres % 0.38% 0.48% 0.55% Dietary P level Alfalfa, corn, soybean rotation with 27 lb P/a removal

33 Summary An integrated approach to improving P nutrient management on dairy farms seems to be having an impact. TMR samples tested in Wisconsin show a trend toward decreased total P levels, bringing them more in line with NRC guidelines It appears that a trend toward reduced dairy dietary feed P levels is being reflected in average manure P levels as well.
