Essential advice for improving cow comfort and nutrition:

1. Cows should be kept in open conditions for free air flow and raised freely, meaning implementing a tether-free cow rearing system.

2. Cows should be bathed at least twice a day.

3. TMR (Total Mixed Ration) feeding system should always be maintained to keep rumen pH at proper levels.

4. Provide cows with 24-hour unrestricted access to drinking water.

5. Calculate nutritional requirements based on energy and protein needs.

6. Provide cows with dry feed by mixing grains and green grass/hay together.

7. Consider green grass as the primary feed for cows and feed it after chopping into small pieces.

8. Avoid feeding cooked rice to milking cows and heifers.

9. Maintain daily records of all expenses and milk production.
