Item	PC	NC	NC + 1,500	NC + 3,000	SEM	P-Value
Jugular blood Insulin3, µg/L	0.042	0.038	0.047	0.049	0.005	0.41
Fasting jugular blood glucose3, mg/dL	97.4	95.2	94.5	95.3	3.28	0.93
Fed jugular blood glucose, mg/dL	175.4	251.0	215.3	207.2	18.74	0.07
Portal vein blood glucose, mg/dL	488.5	477.2	491.9	473.8	7.49	0.27

¹PC, positive control diet with adequate Ca and P; NC, negative control diet with inadequate Ca and P; NC⁺1,500, NC containing 1,500 FTU/kg phytase; NC⁺3,000, NC containing 3,000 FTU/kg phytase.

²Data are means of eight observations per treatment.

³Insulin values were based on one pig per pen, and glucose data represent the average of two pigs per pen.
