Determining the phosphorus release curve for Sunphase HT phytase in nursery pig diets.

A total of 280 pigs (DNA 241 × 600, initially 10.4 ± 0.24 kg) were used in a 21-d study to determine the available P () release curve for Sunphase HT phytase (Wuhan Sunhy Biology Co.

Effects of gruel feeding and oral dextrose on the survivability of pigs after weaning.

Two experiments were conducted in a 14,400 head nursery using 3,087 (experiment 1) and 988 (experiment 2) pigs to determine the effect of gruel feeding (experiment 1) and supplemental oral dextrose (experiment 2) on nursery pig survivability after weaning. Upon arrival to the nursery, for experiment 1, the smallest 10% of pigs were selected and randomly placed in pens with 61 to 108 pigs per pen. Pens of small pigs were assigned to one of two treatments in a completely randomized design.
