1. Colostrum stage: This is the first stage of lactation, occurring immediately after calving. Colostrum is a thick, yellowish fluid that is rich in antibodies and essential nutrients to provide the newborn calf with immunity and energy.
2. Transition stage: This stage occurs in the first few days after calving, during which the cow's milk production gradually increases as she transitions from colostrum to regular milk production.
3. Peak lactation stage: This is the stage when the cow is producing the highest amount of milk, typically occurring around 4-6 weeks after calving. Milk production can vary depending on factors such as genetics, nutrition, and management practices.
4. Mid-lactation stage: This stage occurs after peak lactation and typically lasts for several months. Milk production remains relatively high during this stage, but may start to decline gradually.
5. Late lactation stage: This stage occurs towards the end of the lactation cycle, when milk production starts to decline significantly. The cow's energy requirements decrease as she prepares for drying off and calving again.
6. Dry period: This is the period between lactation cycles when the cow is not producing milk. It allows the cow's body to rest and prepare for the next lactation cycle. Proper management during the dry period is important for the cow's health and future milk production.

Stage 1: Colostrum Phase (First 48 hours)
- Production of thick, yellowish fluid rich in antibodies, nutrients, and growth factors.
- Provides passive immunity to the newborn calf against infections.
Stage 2: Transitional Phase (48 hours to 10 days)
- Gradual decrease in antibody content and increase in milk yield.
- Milk composition becomes similar to normal milk.
Stage 3: Early Lactation Phase (10 days to 2 months)
- Peak milk production.
- High levels of protein, fat, and lactose in the milk.
- Requires adequate nutrition and energy intake.
Stage 4: Mid-Lactation Phase (2 to 6 months)
- Milk production slightly decreases but remains high.
- Milk composition stabilizes.
- Focus on maintaining milk quality and feed efficiency.
Stage 5: Late Lactation Phase (6 months to dry-off)
- Milk production declines gradually.
- Fat content of the milk increases.
- Prepare the cow for dry-off by gradually reducing milk yield.
Stage 6: Dry Period (60 days before calving)
- Cessation of milk production.
- Time for the mammary gland to rest and prepare for the next lactation.
- Proper nutrition and management during the dry period are crucial for subsequent lactation performance.
- Production of thick, yellowish fluid rich in antibodies, nutrients, and growth factors.
