Univ. of Georgia researchers analyzed data from the Georgia Heifer Evaluation and Reproductive Development Program (HERD). The data involved 839 pregnant replacement heifers that were sold over a 6-year period (2000-2005). The objective was to determine factors that affect sale price. Heifers begin the program at approximately 12 mos. of age, and the breeding period begins at about 14.5 mos. of age. Heifers are bred by AI for 30 days, followed by natural service for 35 days, and evaluated for pregnancy by AI 6 weeks following the end of the AI period. Heifers are sold approximately 4.5 mos. following the start of AI.

Average annual sale price ranged from $936 to $1280. Heifers pregnant by AI sold for an average of $1052 while those bred by natural service brought $123 less at $929. Registered and commercial heifers sold for the same average price ($1030). Buyers paid more for heifers that had a greater avg. daily gain, higher frame score, and were more docile. Buyers also tended to pay more if they had purchased heifers in a previous sale (Rossi et al. 2006. Southern Section ASAS. Abstract 127).

It would be important to match mature cow size and milk production to the feed resources that are available on your operation. A mis-match will result in greater feed costs or open females.
