Widespread Challenges in Heifer Vitamin
1. Overconditioning
Excessive vitality consumption might end up in:
- Fat deposition all by means of the mammary gland
- Decreased future milk manufacturing potential
- Calving difficulties
To cease overconditioning:
- Monitor physique state of affairs scores usually
- Modify vitality density of the meals routine as wished
- Current adequate put collectively decisions
2. Underfeeding
Insufficient meals routine can result in:
- Delayed puberty
