In Experiment 1, the impact of using diets sufficient in P on the performance of weaned piglet growth with or without a super dose of phytase was investigated. One hundred and twelve piglets were randomized into four treatments with 7 replicates (4 piglets·cage<SUP>-1</SUP>). Bodyweight (BW), daily gain (ADG), daily intake (ADFI) and feed conversion ratios (FCR) were measured over three weeks. Treatments included a positive control (PC) with a Ca : P ratio of 0.80 : 0.50%. and the negative control (NC) had a Ca : P ratio of 0.60 : 0.50%. The PC plus phytase was denoted as PC+, and the NC with the phytase diet was designated as NC+. The PC diet was formulated to meet or exceed the NRC (2012) standards for pigs weighing 7 - 25 kgs. Better results were obtained with the PC diet (p > 0.1) compared to the NC diet. The super dose of phytase in the PC+ diet significantly improved the overall FCR (p < 0.1). For Experiment 2, the impact of different calcium (Ca)/phosphorous (P) ratios with or without supplementation of vitamin D₃ was determined. Ninety-six piglets were randomized into four treatments with 6 replicates (4 piglets·cage<SUP>-1</SUP>). The PC, NC1 and NC2 diets had ratios of 0.80 : 0.50, 0.80 : 0.45, and 0.60 : 0.45%, respectively. The fourth diet (PCV) was the PC diet fortified with vitamin D₃. Improved results were observed with the PC diet (p > 0.1) compared to the NC diets. Supplementing dietary 25-OH-D₃ in the PCV diet led to numerically higher ADG and ADFI scores with lower FCR values at the early nursery stage (p = 0.0044), but the vitamin supplement did not significantly influence the growth.
