Resumo: | The environmental concerns regarding emission reduction of harmful gases has lead to adaptation of novel means of production and new models. The objective of this study was to monitor the concentration of ammonia in an experimental broiler chicken shed, located in the Department of Animal Science, UFV, with 800 birds distributed in 40 boxes, each with 20 birds. The birds were fed five different diets, constituting the treatments, with four replications. T1 - Diet with high protein and minimal amino acid supplementation, T2 = diet based on the concept of optimal protein; T3 - T1 with phytase supplement; T4 - T1 with organic mineral supplement and; T5- combination of T2, T3 and T4. The Concentration of ammonia was monitored with the use of electrochemical sensor (Quest model Safecheck 100). Data were analyzed with help of SAEG computer program, developed by the University Federal of Viçosa (UFV, 2000). Regression analysis was done at 5% probability. In general, the highest concentrations of ammonia were found in the last week before slaughter, depending on the development of birds. Highest levels of ammonia were found when birds were fed T1 and the lowest when fed T2 and T5. The treatments, consisting of ideal protein (T2 and T5), which has better amino acid profile, reduced nitrogen loss, resulting in reduced production of uric acid in bed, thus reducing ammonia emission. The addition of phytase and organic minerals increased availability of protein. The recommended maximum concentration of ammonia inside the shed is 20 ppm, and in none of the treatments the concentration reached above thus limit. |

Objetivou - se com o estudo monitorar a concentração de amônia, em um galpão experimental para frangos de corte, localizado no Departamento de Zootecnia da UFV, com 800 aves distribuídas em 40 boxes, sendo 20 aves em cada boxe, submetidas a cinco diferentes rações, que constituíram os tratamentos e 4 repetições. T1 - Ração com elevado nível de proteína e suplementação mínima de aminoácidos; T2 – Ração baseada no conceito de proteína ideal; T3 - T1 com suplementação de Fitase; T4 - T1 com suplementação de minerais orgânicos e; T5 combinação dos tratamentos T2, T3 e T4. O Monitoramento da concentração de amônia nos diferentes tratamentos foi realizado com sensor eletroquímico da marca Quest, modelo Safecheck 100. As maiores concentrações de amônia foram detectadas nas últimas semanas antes do abate, em função do desenvolvimento das aves. Maiores níveis foram encontrados no T1 e menores níveis de nos T2 e T5. Os tratamentos, compostos de proteína ideal (T2 e T5), que ofereceram um melhor perfil aminoacídico, favoreceram a redução da perda de nitrogênio, o que reduziu a produção de ácido úrico na cama e, conseqüentemente, a emissão de amônia no galpão. A adição da fitase e minerais orgânicos aumentaram a disponibilidade da proteína para o organismo do animal. A concentração máxima de amônia recomendada internamente às instalações é de 20 ppm, sendo assim, em nenhum dos tratamentos observou-se níveis médios superiores aos limites permitidos para os animais.Universidade Federal de Viçosa - UFV2012-03-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/18110.13083/reveng.v20i1.199Engineering in Agriculture; Vol. 20 No. 1 (2012); 19-24Revista Engenharia na Agricultura - REVENG; v. 20 n. 1 (2012); 19-242175-68131414-398410.13083/reveng.v20i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/181/146Inoue, Keles Regina AntonyTinôco, Ilda de Fátima FerreiraCassuce, Deborah CunhaBueno, Mateus MarquesGraña, Alfredo Lorainfo:eu-repo/semantics/openAccess2023-01-19T13:00:52Zoai:ojs.periodicos.ufv.br:article/181Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:00:52Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
