Summary thermoneutral zones of pigs
Web30 Oct 2024 · Summary In summary, heat stress compromises a variety of production parameters in the swine industry including growth, carcass composition, and … WebFortunately, pigs are highly adaptable and will perform well within a range of temperatures. This range is called the thermoneutral zone. The thermoneutral zone (TNZ) is the range of ambient temperatures at pig level within which a pig can maintain normal body temperature (102.2 ºF) through control of sensible heat loss (Figure 1).
