Selecting replacement heifers using production records, herd goals, and available resources can ensure the correct females are staying in the herd.

As the seasons come and go, the production cycle of the beef herd also changes. Cows calve, calves grow, and replacement heifers are selected. Selecting replacement heifers using production records, herd goals, and available resources can ensure the correct females are staying in the production system.

Just as purchasing a new herd bull can directly impact genetic improvement, selecting replacement heifers that match your production goals and available resources can impact the bottom line. Production records are one tool in the selection process. Maintaining herd records on cow productivity could include; calving date, birth weights, weaning weights, calving assistance, calf survivability, cow BCS, cow characteristics, calving intervals, and temperament. Heifers born from dams needing assistance with calving and nursing because of teat or udder defects or poor temperaments should not be retained. Knowing 50% of a replacement heifer’s genetics come from the dam, analyzing the dam’s collective data before you head out to . . .

T.K. Cheung Lecture in Animal Science: "Using science to assess and improve the welfare of dairy cattle"

Dan Weary is a Professor at the University of British Columbia. Dan did his BSc and MSc at McGill and Doctorate at Oxford before co-founding UBC’s Animal Welfare Program where he now co-directs this active research group. His research focuses on understanding the perspectives of animals and applying these insights to develop methods of assessing animal welfare and improving the lives of animals. His work has helped drive changes in practices (including the adoption of higher milk rations for calves and pain management for disbudding) and housing methods (including the adoption of social housing for pre-weaned calves). He also studies cow comfort and lameness, social interactions among cows, and interactions between cows, human handlers and technologies like automated millking systems that are increasingly used on farms. His presentation will outline key questions in cattle welfare, highlight recent UBC research addressing them, and showcase innovative methods for improving the lives of cattle and their caretakers.
