Depending on market conditions, the cow may be bred with a "dairy bull" or a "beef bull." Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef.

2019年6月20日 · For answers, the researchers have begun breeding a small batch of new cows, cultivated in part from the preserved semen of long deceased bulls, to measure a host of characteristics—height,...

A fresh cow is a dairy term for a cow (or a first-calf heifer in few regions) who has recently given birth, or "freshened." The adjective applying to cattle in general is usually bovine . The terms bull , cow and calf are also used by extension to denote the sex or age of other large animals, including whales, hippopotamus , camels , elk and ...

Dairy cattle are those primarily raised for their milk as part of dairy farming.

2024年5月1日 · These terms apply to both beef cows where cow-calf producers are focused on raising quality beef, and dairy cattle where dairy farms are focused on milk production. This bullet list is a quick cheat-sheet, and we go into much more detail below:

These seven American dairy cow breeds each bring something unique to the table, from high milk yields to rich, creamy butterfat. Whether it’s the iconic Holstein, the golden milk of the Guernsey, or the historical Brown Swiss, dairy farmers and consumers alike benefit from the diversity of these remarkable animals.

Commercial dairy cows are divided into five major breeds: Ayrshire, Brown Swiss, Guernsey, Holstein–Friesian, and Jersey. There are many minor breeds, among them the Red Dane, the Dutch Belted, and the Devon. There are also dual-purpose breeds used to produce milk and meat, notably the Milking Shorthorn and the Red Polled.

Delta’s introduction as one of the first bulls with gender-sorted semen revolutionized the dairy sector, increasing the likelihood of female offspring. His remarkable genetic profile, including robust health features, essential production, and storage type attributes, has opened the path for further acceptance of gender-sorted semen.

The database for dairy cattle is foundational for the genetic advancement that has been accomplished over the last 70 years. DHI records, classification scores, herd health and fertility data, and genomic markers combined to represent many millions of data points to base genetic estimates on. There are now over ten million dairy animals in the ...

These tools transformed dairy cattle breeding on a monumental scale, leading to profound changes and advancements in the industry, especially for yield traits and mammary systems. With the advent of genetic research, an expansion in data for new heritable traits, and enhanced genomic evaluation procedures, the dairy cattle breeding industry ...
