Question

For developing replacement heifer:

1. What should we know about key weight percentages and timing?

2. What should we know about low post-weaning gains?

3. What should we know about high post-weaning gains?

Answer 1

When developing replacement heifers, it is important to monitor key weight percentages and timing. Low post-weaning gains can impact reproductive performance, while high post-weaning gains may interfere with reproductive development.

Step-by-step explanation:

Key Weight Percentages and Timing:

When developing replacement heifers, it is important to monitor their weight percentages at key stages of growth. For example, it is recommended that replacement heifers reach 55 to 65% of their mature weight by the time they are bred. This ensures that they have reached sufficient size and maturity to handle the demands of pregnancy and calving.

Low Post-Weaning Gains:

Low post-weaning gains in replacement heifers can have negative effects on their reproductive performance. It is important to provide adequate nutrition during this stage to support growth and development. Low gains may indicate insufficient feeding or health issues that should be addressed.

High Post-Weaning Gains:

High post-weaning gains in replacement heifers can also be problematic. Rapid weight gain can lead to excessive fat deposition and may interfere with proper reproductive development. Moderation in weight gain is important to ensure balanced growth and future fertility.
