Nutrition and fertility in dairy cows

Nutrition affects the conditions supporting reproductive performance, particularly around transition and early lactation. Excessive condition loss before or after calving can be associated with poorer pregnancy outcomes. (Penn State Extension)

More than one nutrient

After calving, increasing energy demand combined with restricted intake can create negative energy balance and fat mobilisation. Health and housing problems may deepen the drop in intake. (Penn State Extension)

A nutrition and fertility review considers energy, protein and minerals in relation to requirements and the complete diet. More supplementation should not automatically be assumed to improve results. (MSD Veterinary Manual)

Condition records describe a process

Regular BCS records should be assessed alongside lactation stage and earlier observations. Excessive or inadequate condition and rapid changes can accompany health and production problems. (Penn State Extension)

Appropriate condition is not established in the final few days before calving: it requires management throughout lactation. Penn State emphasises maintaining condition during the dry period rather than trying to make abrupt corrections during transition. (Penn State Extension)

Plan a joint review

• Current feed analyses, the ration and actual dry-matter intake. (University of Minnesota Extension)
• Individual BCS and changes before and after calving. (Penn State Extension)
• Reproductive and health records for the herd veterinarian to compare with feeding information.

Do not interpret every failed insemination as evidence of a mineral shortage. Ask your veterinarian and nutrition adviser to assess herd data before introducing another programme change.

Read about ration balancing and ketosis. Explore liquid supplements as part of the feeding offer and contact AquaBlend for selection advice.
