Determining the threonine requirement of the high-producing lactating sow
Posted in: Nutrition, Pork Insight Articles by admin on July 6, 2017
To minimize sow body tissue breakdown, the threonine requirement was found to be 37, 40 and 39 g total threonine/d (29, 31 and 30 g Dthr/d) for parity 1, 2 and 3+ sows, respectively. To maximize litter growth, the threonine requirement was found to be 37, 39 and 38 g Tthr/d (28, 30 and 30 g Dthr/d) for parity 1, 2 and 3+
sows, respectively. The maintenance requirement for threonine in the sow is 41 mg Tthr/kg BW^0.75 (Pettigrew, 1993). The threonine requirement for litter growth in this study was 14.3 g Tthrlkg litter growth. Using these requirements for maintenance and litter growth, pork producers can calculate the threonine requirement of lactating sows on their farms.
