Over the past several decades, beef cows have quietly gotten bigger. In 1975, the average beef cow weighed just over 1,000 pounds; by 2009, that number had jumped to 1,350 pounds, and today, many herds include cows tipping the scales at 1,400 pounds or more.

Choosing beef replacements is a foundational decision that affects herd productivity, profitability and long-term genetic progress. Whether you raise replacements on-farm or purchase them, understanding the economic, genetic and management implications is key to making informed decisions.

Historically, the objective of supplementation programs for grazing cattle has been to address nutrient deficiencies based on the difference between animal nutrient requirements and the nutrients provided by the forage, with emphasis on improving forage utilization and animal performance.

The use of virtual fence technology using GPS collars with the ability to provide audio and electrical cues may offer an economical management tool to strategically graze areas based on specific land and livestock management objectives.
