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:
| Shade | Sprinklers | |
| Average daily gain (pounds) | 2.98 | 2.56 |
| Dry matter intake (pounds) | 21.65 | 20.93 |
| Feed: gain | 7.42 | 8.52 |
