Think about this?
1. Which breed produced the most total pounds of milk? Why do think this is
so?
2. Why would butterfat be important to milk?
3. What breed produced the lowest total pounds of butterfat?
4. What would you think the most popular breed of Dairy cattle would be
judging from this data? Why?
5. What is the definition of milk production? Why would a cow be lactating?
