Introduction

Heifer growth is often compared to breed requirements to determine "normal" progress. Us designed breed-specific, printable growth Charts that may be supplied to plot heifer development by hand. The charts are based on the results of measure a big number of heifers of various breeds transparent the united States throughout 1991 and 1992. Most of the data was gathered from herds in which the average age at very first calving was slightly higher than 24 months. As a result, the heifers most likely were smaller sized for any type of given age than those found on today"s well-managed dairy farms that calve heifers at 22 to 24 month of age.

The Holstein heifer expansion charts show several percentiles that the U.S. Population, allowing a producer to compare an individual heifer to every others and also to set growth goals. Maintaining a bulk of heifers close to the 75th percentile and the entire herd in between the median and also the 95th percentile is an achievable goal.

For all various other breeds, the recommended development ranges shown are in between the average and the top 67th percentile that the population. To achieve early calving (24 month or less) and also high manufacturing potential, separation, personal, instance heifers should loss near the height of or slightly above the selection shown.
