Improving the Productivity of Beef Heifers in Florida

Figure 1. Illustration of proper hip height measurement.Beef replacement heifers are a necessary but costly part of every cow-calf operation. A decision needs to be made to either purchase replacement heifers or raise them on the ranch. This is a long-term decision that will affect the ranch for many years through the genetics of the replacement heifers and through equipment and management inputs. This 9-page fact sheet provides an analysis of considerations for raising replacements; factors to consider in selection; and recommendations for nutritional management.

The ability to measure performance is a key component in all beef cow operations, and measuring production efficiency is becoming increasingly important. Regardless of size, producers must be able to identify the current status of their operation in order to make adjustments toward improvement. Identifying and culling the cows within the herd that are less efficient at producing a weaned calf in the environment and management system used on the ranch can be a powerful tool to improve the herd.
