The Threonine Requirement of the Sow in Lactation
The threonine requirement of a high-producing sow in lactation was determined as threonine is the second limiting amino acid in most swine diets. Tissue breakdown was minimized in sows by having a threonine requirement of 37.3, 40.0 and 38.9 g total threonine/d (28.7, 30.8 and 30.0 g of digestible threonine/d) for parity 1, 2 and 3+ sows. A threonine requirement of 36.6, 39.2 and 38.2 g total threonine/d (28.2, 30.2 and 29.5 g digestible threonine/d) for parity 1, 2 and 3+ sows was found to maximize litter growth.
