Beef Cattle Science

 

 Beef Cattle

Over half of the 64,000 farms in Kansas raise cattle, with over 5.7 million head marketed annually. In 2003, cash receipts for all Kansas commodities was slightly over 9 billion dollars. Of this, approximately 62% of the total cash receipts in Kansas came from cattle and calves. 

Nationally, Kansas ranks first in the number of cattle processed (approximately 8.2 million or about 23% of the U.S. total), second in fed cattle marketing (approximately 5.4 million or about 22% of the U.S. total), and seventh in beef cows (approximately 1.5 million or about 5% of the U.S. total).

Additionally, Kansas producers graze or background about 2.5 to 3.0 million stockers annually. Without question, beef production is the economic workhorse of Kansas agriculture.

Bio Brief

John Jaeger began working at K-State Research and Extension's Agricultural Research Center in Hays on January 1, 2006. He had previously worked at the center from 1986-1994 as a research assistant and cow-calf herdsman.

Jaeger earned bachelor's, master's and doctoral degrees from Oregon State University. His expertise is in reproductive physiology.

From 1994 to 2000, he worked as a research assistant and ranch manager at OSU's Eastern Oregon Agricultural Research Center in Union, OR.

He is particularly interested in cow-calf production systems that will result in value-added beef carcasses. Early weaning of calves may be a low-cost sustainable system that will reduce cow maintenance costs as well as improving cow performance and carcass quality of offspring.
