BFNMP$

BFNMP$• Step 1: Animal Management– 5000 head feedlot– 100 head per pen– Cattle:• 750 to 1300 lb• 23 lb DMI• 144 days on feed

– Diet• Vary N and P content

BFNMP$

• Step 2: Manure Management– Equipment• 4 yd loader• 20 ton truck mounted spreader• 2 hrs per pen• $3.00/gallon fuel• $12.00/hour labor

BFNMP$

• Step 2: Manure Management– Open lot– Stockpiled for >100 days– Immediate incorporation– Vary N volatilization

BFNMP$• Step 3: Crop Management– 80 acre fields– 50% in crops and available to feedlot

– Corn-soybean rotation• Corn yield 157 bu/acre• Soybean yield 42 bu/acre

BFNMP$

• Step 3: Crop Management– Fertilizer Prices• $0.55/lb N ($0.25/lb urea)• $0.67/lb P ($0.30/lb P2O5)

• $0.53/lb K ($0.32/lb K2O)

– Vary application rate N or P based

Impact of Diet

• Grain based, traditional diet– 13.3% CP– 0.3% P• Vasconcelos and Galyean, 2007

• 40% Distillers Grains diet– 18.7% CP– 0.5% P• Vander Pol et al., 2006

Impact of N volatilization

• Summer– 70% N volatilization

• Winter– 50% N volatilization

• Intensive manure management– 20% N volatilization– ongoing research

Conclusions

• Impact of Diet– 40% Distillers Grains diet increased manure value

by $8.17/head– Increased revenue by $6.92/head

• Impact of Application Rate– Apply on a 4 year P rate

• Impact of N volatilization– Difference between 70% and 20% N Volatilization

is $61,784
