Pregnancy Timeline & Milestones
Week 1-3: Early Development
Fertilization occurs and embryo implants. No visible signs of pregnancy. Continue normal feeding routine.

Week 7-10: Fetal Growth
Rapid fetal development. Pregnancy may be confirmed via ultrasound. Increase nutrition gradually.
Week 11-15: Mid-Pregnancy
Visible abdominal enlargement. Udder development begins. Maintain quality hay and fresh water.
Week 16-20: Late Development
Significant weight gain. Kids are rapidly growing. Begin increasing grain portions and protein.
Week 21-22: Pre-Kidding
Udder fills, ligaments soften. Prepare kidding area. Monitor closely for signs of labor.
