Milk Production Background Information One trait a dairy farmer desires in their cows is high milk production (milk yield). Holstein cows (image below) are nown for producing high yields of milk-making them the most popular dairy breed. Through selective breeding, lairy farmers select their top-producing cows who produce high amounts of milk each year. High producing ows will pass on their milk production traits to future generations. Diamond D Dairy is located in Petaluma, CA. Diamond D is looking to increase their herd's milk production with he next generation of calves. They measure their cows' milk production by the pound, per lactation period. A actation period typically lasts 305 days. Diamond D has six remaining cows left to choose from.

**Milk Production Background Information**

One trait a dairy farmer desires in their cows is high milk production (milk yield). Holstein cows (image below) are known for producing high yields of milk—making them the most popular dairy breed. Through selective breeding, dairy farmers select their top-producing cows who produce high amounts of milk each year. High producing cows will pass on their milk production traits to future generations.

**Butterfat Content Background Information**

Besides measuring how many pounds of milk a cow produces, dairy producers also measure the protein and butterfat content of their herd’s milk supply. Jersey cows (image below) are known for high butterfat content in their milk. Dairy farmers use selective breeding to select cows who produce high amounts of butterfat. This helps improve the butterfat content in the herd’s milk supply. High butterfat content in milk is a desirable trait because it helps produce quality cheese. Cheese processing companies often purchase milk from dairies that is high in butterfat.
