Effects of primary calcium source on phytase efficiency in weaned piglets.

ABSTRACT: An 18-d experiment tested the hypothesis that using calcium formate (Ca-formate) instead of limestone in piglet diets, lowers the dietary buffering capacity, reduces stomach pH, and improves phytase efficiency. At weaning (29.8 ± 1.10 d), 60 boars (body weight 8.8 ± 0.31 kg) housed in metabolism crates were allotted to a randomized complete block design with 10 experimental diets and 2 weaning rounds. Diets were formulated following a 5 × 2 factorial design with 5 dietary treatments (Trt) and 2 main Ca sources (limestone or Ca-formate). The 5 Trt included a positive control diet [PC; 0.76% Ca, 0.34% standardized total tract digestible (STTD) P] and 4 negative control diets (NC; 0.56% Ca, 0.21% STTD P) supplemented with phytase at 0, 750, 1,500, and 3,000 FYT/kg. At day 10, piglets were ind
