Heifers benefit from shade.
According to a study in the February Journal of Dairy Science, giving heifers in dry-lot pens access to shade in hot weather improved their growth and feed efficiency compared to cooling heifers with sprinklers only.
Here is a look at heifer performance during the study:
|Average daily gain (pounds)||2.98||2.56|
|Dry matter intake (pounds)||21.65||20.93|
