Hoop Structures for Other Livestock

Hoop Barns for Sheep

More housing examples:

Hoop barns work well for lambing and feeding out market lambs. They are flexible so pens for lambing during cold weather can be provided and the layout can be changed later to provide feed bunks for market lambs. Table 1 (below) gives design data for sheep.

Sheep tend to thrive in cool but dry environments which hoop barns provide when they are well ventilated. Sidewall curtains and end wall openings help to promote good ventilation, thereby keeping the humidity and ammonia to minimum levels.


Figure 1. End wall openings and sidewall curtains can be utilized to help provide good ventilation and reduce levels of ammonia and humidity, which is important for animal comfort and health.

Figure 2. The interior of sheep barns can be changed depending on your production needs.

Figure 3. Be sure to maintain a suitably cool, dry environment for sheep.
