Resumo: | 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 –­­ basal feed; T2 – basal feed without micromineral-vitamin supplement; T3 – basal feed with phytase and without micromineral-vitamin supplement; T4 – basal feed 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.KEYWORDS: Enzyme, finishing phase, pig, ration, weight gain. |

Utilizaram-se 24 fêmeas suínas, híbridas com peso médio inicial de 66 ± 1,4 kg e peso final médio de 106 ± 1,8 kg. Foi utilizado o delineamento experimental inteiramente ao acaso com seis tratamentos e quatro repetições, sendo dois animais por unidade experimental. Os tratamentos utilizados foram: T1 –­ ração basal, T2 – ração basal sem suplemento micromineral-vitamínico, T3 – ração basal sem suplemento micromineral-vitamínico com fitase, T4 – ração basal sem suplemento micromineral-vitamínico e sem 1/3 de fósforo inorgânico com fitase, T5 – ração basal sem suplemento micromineral-vitamínico, sem 2/3 do fósforo inorgânico com fitase, T6 – ração basal sem suplemento micromineral-vitamínico, sem fósforo inorgânico e com fitase. A retirada do suplemento micromineral-vitamínico, a redução dos níveis de fósforo inorgânico e a adição de fitase não influenciaram (P>0,05) as características de carcaça, mas reduziram (P<0,05) o consumo e o ganho de peso com pior conversão alimentar. Da mesma forma, a redução de fósforo e a adição de fitase, nas condições deste experimento, não apresentaram viabilidade econômica comparado às rações basais.PALAVRAS-CHAVES: Conversão alimentar, enzima, ganho de peso, terminação.Universidade Federal de Goiás2010-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/453410.5216/cab.v11i4.4534Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 11 No. 4 (2010); 775 - 783Ciência Animal Brasileira / Brazilian Animal Science; v. 11 n. 4 (2010); 775 - 7831809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/4534/8351https://revistas.ufg.br/vet/article/view/4534/8718Oliveira, Ana Paula Azara deNunes, Romão da CunhaRoner, Márcia Nunes BandeiraStringhini, José HenriqueRufino, Luciana MouraFarias, Leonardo Attainfo:eu-repo/semantics/openAccess2010-12-21T13:36:26Zoai:ojs.revistas.ufg.br:article/4534Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:16.065123Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
