What is Cow-Calf Operations? 0 Cow-Calf Operation is a method of raising beef cattle in which a permanent herd of cows is kept by a farmer or rancher to produce calves for later sale. How does it work? 0 The producers role is to produce a calf to be used in the beef market. They can only produce one calf every 12 months. 0 A cow carries a calf for 9 months before it gives birth. Then she nurses it for another 6 months before it is weaned and sold. We can rebreed a cow 3 months after she has given birth that way she is carrying her next calf while she is nursing one. Different types of Cow-Calf Operations 0 Commercial Operations-Generally involves cross-bred cows that are bred to produce calves that are mainly for beef production. 0 Seedstock Operations- Where producers raise a favorite breed (sometimes more than one) and breed cows to get calves that are grown and sold to other producers for replacement stock. Advantages/Disadvantages 0 Forages: 0 Forages are the man food source for all cow-calf operators. 0 Less labor requirements: 0 Most all of the labor required is for maintenance of the ranch. 0 Low death loss: 0 Insures good profits and cattle just don’t lose their offspring. 0 Don’t convert grass as good as feed: 0 Cattle don’t convert grass to body weight as quickly as they do with feed. 0 High cost to start an operations: 0 It cost more to get started with cattle than any other species. EPD Basics 0 EPD stands for Expected Progeny Difference. 0 EPD’s predict the performance of future offspring from an individual animal. 0 Each EPD is an estimate of the individual’s genetic merit for producing future progeny. 0 A bull with “superior” EPDs does not guarantee you superior calves. What EPD’s are Not 0 Predict average differences between sires- not actual performance. 0 EPD’s do not predict uniformity or variation in calf crop. 0 Not an absolute guarantee. 0 Not static. 0 Breed Average EPD for any trait is not necessarily. 0 Not Directly comparable across breeds. Challenges with EPD’s 0 Balanced trait selection 0 Which traits? 0 Proper weighting 0 Economic value of each EPD 0 Relative to a unit change 0 Relative to its importance in selection Facts about Cow/Calf Operations 0 Based on the U.S. Census of Agriculture, less than 3 percent of all cow-calf producers obtained all of their income from farming. 0 Producers on operations with 50 beef cows devoted an average of 28.9 percent of their work time to the operation compared with 47.3 percent for operations with 50 to 99 beef cows. 0 Small-scale cow-calf operations. 0 There is over 200 by products that come from a cow. Facts about Cow-Calf Operations Continued 0 Cow-Calf Operator- conception to weaning = 15 months. 0 Backgrounder- raises the weaned calves until they are ready to go to the feedlot. This process takes about 4-6 months. 0 Feedlot- fattens the cattle until they are at slaughter weight (1400-1600 lbs.) which takes 5-6 months. 0 Total time that is required to get the beef to the consumer: 0 First thought of the next calf crop to the table- just over 2 years. 0 From the birth to the table- right at 16-17 months.
