Strategies for Auditing Rations and Reducing Milk FlowApril 22, 2020Jessica Gard
Ration Audit Strategies to Reduce Costs
1. Does the additive affect health/ reproduction?
- Yes → Leave in ration.
2. Does the additive or nutrient affect milk volume or component concentrations?
- Yes, protein yield → Leave in the ration.
– Protein remains valuable in most federal orders and for most processors (excluding some parts of the Mid-Atlantic
– Cost effective options: Animal proteins including feather meal and RP Met
- Yes, butterfat yield → Remove from the ration.
– Additive can be re-added when fat values return and response is rapid (i.e. MHA, Palm Fat)
Strategies in Combination to Reduce Production Yet Maintain Protein Yield
1. Increase Culling
- If the market exists for the animals, cull to immediately lower production.
- Focus on cows with high SCC and those requiring 3+ breeding services to achieve pregnancy.
2. Dry off early/alter milking frequency
- Dry off cows that are 200+ days carried calf (DCC) to immediately reduce the herd’s milk volume.
- Another alternative is to switch from 3X to 2X milking.
– It is vital to start with fresh cows <21 DIM and late lactation cows >150 DIM to avoid unnecessary discomfort and
health complications during peak production.
– Utilizing this strategy will cause the longest delay in returning to normal production levels.
3. Evaluate the ration
- Increasing forage uNDF30 and decreasing starch will naturally reduce milk yield.
– This strategy involves increased forage feeding which may require additional inventory/ purchase.
– As an example, increase forage uNDF30 to 6 lb/ head or greater, decrease starch to 20% of ration DM.
- Non-forage fiber sources can be used, however, in post peak cows it will be necessary to reduce non forage fiber to reduce
4. Feed milk to cows and calves
- Over base milk can effectively be fed to cows, heifers, and calves.
- For calf feeding, pasteurization is required.
- For heifers and cows, please review the following guidelines: Feeding Unpasteurized Milk to the Dairy Herd
5. Use milk as fertilizer
- Considering milk is high in P, N, K and other nutrients, it can be recycled and used as crop fertilizer.
- For environmental safety and farm viability, please review the following guidelines: Provisional Guidance: Using SurplusMilk as Fertilizer Due to the COVID-19 Emergency
