- Intake is affected by:
- Palatability
- Time they have access to feed
- How has feed access changes over the years?
- How did we used to offer feeds?
- Concentrate feeding levels should be appropriate for each operation
Unit 9: Dairy Cattle Feeding - Steps in Ration Balancing for Lactating Dairy Cattle
- Establish needs
- Maintenance plus milk production & reproductive needs
- Determine feeds available
- Establish feeding levels
- Forage
- Appropriate for quality and production
Unit 9: Dairy Cattle Feeding - Balance
- Make sure protein & energy needs are met
- Evaluate forage : concentrate ratio
- Check protein sources and amino acid levels
- Ensure proper min/vit supplementation
- Feeding Guidelines
- Groups can be separated based on:
- Stage of lactation
- Age
- Dry period
- What groups can/should we have?
Unit 9: Dairy Cattle Feeding - Early Lactation or Post-fresh Group
- 0 – 60 or 70 DIM
- Milk production increases rapidly, peaks 6-8wks post-calving
- Avoid excessive levels of grain
- Encourage forage intake
- Keep it palatable
- High dietary protein
- Limit urea content
- Increase energy density (increase fat content)
Unit 9: Dairy Cattle Feeding - Peak Milk
- Highest DMI’s
- 60 – 140 DIM
- Maximal DMI during peak milk increases total milk production – each 1# peak milk = 300#’s milk in lactation
- Feed several times/d
- Maximize ration forage content without compromising energy, protein, and amino acids
- Mid to Late Lactation
