1 Managing Nutrients through Precision Feed Management Paul Cerosaletti Cornell University Cooperative Extension of Delaware County

2 New York State The Delaware County Precision Feed Management Program: – Where are we?

3 Why is P Increasing? MASS BALANCE: MASS BALANCE: INPUTS to basin = 171,300+ kg/yr NET P ACCUMULATION = 106,300+ kg/yr in basin (soils) OR ~ 5 kg P/ha agr. land/yr OUTPUTS from basin in kg/yr = 65,000 kg/yr

4 The Dairy Farm Mass Nutrient Balance Feed Fertilizer Bedding Animals Imported Nutrients Exported Nutrients Crops Milk Animals Manure LeachingRun off Nutrient Losses to water Farm Boundary Nutrients remaining on farm

5 Feed Management Recognized Council for Agricultural Science and Technology (CAST) – Issue Paper 21, 2002 Council for Agricultural Science and Technology (CAST) – Issue Paper 21, 2002 Animal diet modification to decrease the potential for nitrogen and phosphorus pollution Animal diet modification to decrease the potential for nitrogen and phosphorus pollution USDA-NRCS 592 Nutrient Management Planning Standard USDA-NRCS 592 Nutrient Management Planning Standard Identifies Feed Management as part of a comprehensive nutrient management plan Identifies Feed Management as part of a comprehensive nutrient management plan

6 The Delaware County Precision Feed Management Program What are we? What are we? A program where county based Extension specialists and University faculty work with dairy farmers and their feed advisors to improve farm economic viability and reduce nutrient imports, accumulations, and manure nutrient excretions on dairy farms through feed management.

7 The Delaware County Precision Feed Management Program: What do we do? Research & Development Farm Precision Feed Planning Education Integration

8 Research & Development Farm PFM Planning Education Integration Farm PFM plan development PFM plan implementation Documenting Impacts Farmer education Feed Industry training Field research Model Application/Development

9 Precision Feed Management: The Process Precision Diet Formulation & Delivery Implementation of High Forage Diets Improved Homegrown Forage Production - Reduced Purchased Feed Nutrient Imports - Reduced Manure Nutrient Excretions - Reduced Nutrient Accumulations - Improved Farm Profitability - Reduced Purchased Feed Nutrient Imports - Reduced Manure Nutrient Excretions - Reduced Nutrient Accumulations - Improved Farm Profitability Reduced Nutrient Overfeeding Improved Nutrient Utilization

10 Precision Feed Management Planning What it Entails

11 PFM Planning What it entails What it entails Forage Management Planning Forage Management Planning Feeding Management Planning Feeding Management Planning Diet modeling and monitoring Diet modeling and monitoring Farm Precision Feed Planning

12 PFM Planning PFM Team meets with Farmer and Feed Consultant PFM Team meets with Farmer and Feed Consultant Set goals Set goals Evaluate Corn, Hay and Pasture systems Evaluate Corn, Hay and Pasture systems Assess weak links Assess weak links Develop Annual farm forage plan (strategies/tactics) Develop Annual farm forage plan (strategies/tactics) Provide technical assistance Provide technical assistance Forage Management Planning

15 Precision Feed Management: Feeding Management Planning and Implementation Diet Modeling and Monitoring

16 If you cant measure it, and monitor it, you cant manage it.

17 Dietary Monitoring and Modeling Data Collected Data Collected Feed Composition and intake (inc. refusals) Feed Composition and intake (inc. refusals) Environmental conditions (temp, humidity) Environmental conditions (temp, humidity) Animal Production (milk, fat, prot., body condition, bodyweight) Animal Production (milk, fat, prot., body condition, bodyweight) Purchased feed costs Purchased feed costs

18 Dietary Monitoring and Modeling Rations Modeled Rations Modeled Using Cornell Net Carbohydrate and Protein System (CNCPS) model Using Cornell Net Carbohydrate and Protein System (CNCPS) model Ration metrics generated Ration metrics generated

19 Dietary Monitoring and Modeling: Ration Metrics P density P density P intake P intake P excretions P excretions CP density CP density N excretion N excretion NFC density NFC density Ration Forage content, % of ration DM Forage NDF intake, % of BW Purchased grain costs Several measures

20 Dietary Monitoring and Modeling: Ration Metrics Benchmarks: P intake P intake +/- 5 grams/d of requirement +/- 5 grams/d of requirement Rumen Nitrogen Balance Rumen Nitrogen Balance <100 grams/day <100 grams/day Forage, % of total ration DM Forage, % of total ration DM > 60% > 60% Forage NDF intake, % of BW Forage NDF intake, % of BW > 1.0% > 1.0% Purchased Feed costs - ? Developing benchmarks Purchased Feed costs - ? Developing benchmarks

25 Precision Feed Management Impact

26 PFM Impact to date: - Quantified 20% of herds meet ration goals already 20% of herds meet ration goals already Reduced feed P Imports and manure P excretions avg. of 6.5 kg/cow/yr (25% & 30% respectively) Reduced feed P Imports and manure P excretions avg. of 6.5 kg/cow/yr (25% & 30% respectively) Reduced manure Nitrogen excretions an avg. of 23.4 kg/cow/yr Reduced manure Nitrogen excretions an avg. of 23.4 kg/cow/yr Reduced P accumulation avg. of 40% Reduced P accumulation avg. of 40% Cut feed costs (as high as $128/cow/yr) Cut feed costs (as high as $128/cow/yr) Increase milk production (as much as 3000 lbs per cow/yr) Increase milk production (as much as 3000 lbs per cow/yr)

27 Other Areas of PFM Impact: Not yet quantified: Not yet quantified: Animal health (economic and pathogens) Animal health (economic and pathogens) Lactating cows Lactating cows Transition cows (calf health) Transition cows (calf health) Heifers Heifers Soil Erosion Soil Erosion Crop rotations Crop rotations Crop species Crop species Crop systems Crop systems

28 Other Areas of PFM Impact Adoption of advanced ration software (CNCPS/CPM Dairy) by 50% local feed industry for their everyday ration work. Adoption of advanced ration software (CNCPS/CPM Dairy) by 50% local feed industry for their everyday ration work.
