The experiment aimed to evaluate the effect of phytase enzyme in rations for swine at the finishing phase without the use of mineral-vitamin supplement and with reduced levels of inorganic phosphorus on performance and carcass characteristics, ashes and mineral percentage in the bones and economic viability. Twenty-four hybrid females with starter weight of 66 ± 1.4 kg and final weight of 106 ± 1.8 kg were housed for 38 days in 24 stalls and allotted in a completely randomized experimental design with six treatments and four replications of two animals each. The following treatments were used: T1 –basalfeed; T2 – basal feed without micromineral-vitamin supplement; T3 – basal feed with phytase and without micromineral-vitamin supplement; T4 – basalfeed with phytase, without micromineral-vitamin supplement and without 1/3 of inorganic phosphorus; T5 – basal feed with phytase, without micromineral-vitamin supplement ans without 2/3 of inorganic phosphorus; and T6 – basal feed with phytase, without micromineral vitamin supplement and without inorganic phosphorus supplementation. The withdrawal of the micromineral-vitamin supplemet, the reduction of inorganic phosphorus level and the addition of phytase enzyme did not affect (P>0.05) the carcass characteristics, but they reduced (P<0.05) feed intake and weight gain, and showed worse feed conversion. Likewise, reduction of inorganic phosphorus levels and phytase addition did not improve economic efficiency when compared to basal feed. |
