Effect of protein and energy intake by primiparous sows during lactation on sow and litter performance and sow serum thyroxine and urea concentrations



Effect of protein and energy intake by primiparous sows during lactation on sow and litter performance and sow serum thyroxine and urea concentrations



Journal of Animal Science 64(4): 1060-1069



The effects of protein and energy intakes by primiparous sows during a 28-day lactation on thyroxine (T4) and urea concentrations in blood serum of sows, and sow and litter performance were examined in 2 experiments (Exp.). Dietary treatments were protein intakes of 380 (LP) and 760 (HP) g crude protein daily and energy intakes of 8 (LE) and 16 (HE) Mcal metabolizable energy (ME) daily in a 2 x 2 factorial arrangement.
