Abstract

The present study was conducted to investigate the effects of dietary type and phosphorus (P) level on the post-ileal P digestibility and digestible P content for growing pigs. Thirty-two barrows with average body weight of (34.1±1.2) kg fitted with T-cannula were used in a randomized complete block design with a 2×2 factorial arrangement of 4 treatment, there were 8 replicates per treatment with 1 pig per replicate. The corn-soybean meal (CSBM) and wheat-soybean meal (WSBM) diets supplemented with or without inorganic were used to study the effects of dietary type and P level on the estimation of ileal and post-ileal digestibility of P for growing pigs. The results showed that pigs fed the WSBM diet had greater ileal and fecal P output than pigs fed the CSBM diet (P<0.01). Therefore, ileal digestible P, total tract digestible P, apparent ileal P digestibility and apparent total tract P digestibility were greater in the WSBM diet than that in the CSBM diet (P<0.01). Regardless of diet type, dietary inorganic P supplementation significantly increased dietary total P intake, ileal P output, ileal digestible P, total tract digestible P, apparent ileal and total tract digestibility of P (P<0.01). There were no influences of diet type and dietary P level on post-ileal digestible P and apparent post-ileal P digestibility (P>0.05). The differences between apparent ileal and total tract P digestibility were 9.69%, 6.79%, 9.36% and 10.53% for pigs fed the CSBM diet at low P level, the CSBM diet at high P level, the WSBM diet at low P level and the WSBM diet at high P level, respectively (P<0.05). In conclusion, there is a minimal amount of post-ileal digestible P for growing pigs. However, the amount of post-ileal digestible P and post-ileal P digestibility are not affected by diet type and dietary P level.
