Resumo: | The health of birds can be harmed by ammonia in high concentrations, affecting the respiratory system, compromising the performance of the birds, as well as the entire production system. The use of zeolite in the feeding of laying hens can reduce the emission of ammonia present in the excreta of birds into the environment through the adsorption process. The objective of this study was to evaluate the effects of supplementing zeolite (Clinoptilolite) levels in the feeding of laying hens in the laying phase at 54 weeks of age. The treatments were a control diet free of zeolite and five diets including increasing levels of zeolite (0.7, 1.4, 2.1, 2.8 and 3.5%). A randomized block design was used a total of 240 laying hens of the Isa Brown lineage were used, with eight replicates of five birds per plot, fed the experimental diets for four periods of 28 days. Evaluations of productive performance, egg quality, ammonia and excreta pH, organ weight (liver, pancreas, heart, intestine, proventriculus and gizzard) and measurement of in-testine and cecum length, hematology, serum biochemistry were carried out. The results were submitted to ANOVA and Dunnett's test and regression analysis at 5% probability. There was no significant effect of clinoptilolite levels on production. On the other hand, for the ammonia and pH variables, a linear plateau effect was observed through. Ammoniacal N and excreta pH differed from the control diet for all clinoptilolite levels, in which ammonia volatilization and excreta pH reduced by 46.9% and 4.6% when consuming the diets with 0.93% and 1.19% clinoptilolite, respectively. The reduction in excreta pH is justified by the protonation of ammonia (NH3) into ammonium ions (NH4+). There was a statis-tical difference for the absolute weight of the organs, it was verified through the test of means, higher liver weights in the inclusion levels with 2.1 and 2.8% of clinoptilolite, a relative increase of 24.6 and 15. 9%, respectively. In relation to the length of the intestine, it was greater for treatments 1.4; 2.1 and 2.8% clinoptilolite. Hematological and serum biochemical values did not differ between treatments. Thus, it was observed that the inclusion of clinoptilolite can be used to feed commercial laying birds up to 0.93% inclusion without affecting production performance and egg quality. |

A utilização da zeólita na alimentação de galinhas poedeiras pode reduzir a emissão de amônia presente nas excretas das aves para o ambiente, mediante ao processo de adsorção. Objetivou-se avaliar os efeitos da suple-mentação de níveis de zeólita (Clinoptilolita) na alimentação de galinhas poedeiras na fase de postura com 54 semanas de idade. Os tratamentos foram dieta controle isenta de zeólita e cinco dietas com inclusão de níveis crescentes de zeólita (0.7, 1.4, 2.1, 2.8 e 3.5%). Utilizou-se o delineamento em blocos casualizados, sendo utilizadas 240 aves poedeiras da linhagem Isa Brown, com oito repetições de cinco aves por parcela, alimentadas com as dietas experimentais durante quatro períodos de 28 dias. Foram realizadas avaliações de desempenho produtivo, qualidade de ovos, volatilização da amônia e valor de pH das excretas, peso dos órgãos (fígado, pâncreas, coração, intestino, proventrículo e moela) e medição do comprimento do intestino e cecos, hematologia e bioquímica sérica. Os resultados foram submetidos a ANOVA e ao teste de Dunnett e análise de regressão a 5% de probabilidade. Não houve efeito signi-ficativo dos níveis de zeólita na produção. Por outro lado, para as variáveis amônia e pH observou-se efeito linear platô. Os teores de N amoniacal das excretas diferiram em relação a dieta controle para todos os níveis de zeólita, enquanto que para o pH houve menores valores nos níveis de 0,7 e 1,4% de inclusão de zeólita, sendo que a volatilização da amônia e o valor de pH das excretas redu-ziram em 46,9% e 4,6%, ao consumirem as dietas com 0,93% e 1,19% de zeólita, respectivamente. Houve diferença estatística para o peso absoluto dos órgãos através do teste de médias, em que maiores pesos de fígado foram encontrados nos níveis de inclusão com 2,1 e 2,8% de zeólita, com um aumento relativo de 24,6 e 15,9 %, respectivamente. Com relação ao comprimento do intestino, foi maior para os tratamentos 1,4; 2,1 e 2,8% de zeólita. Valores hematológicos e bioquímica sérica não diferiram entre os tratamentos. Dessa forma, observou-se que a inclusão da zeólita pode ser utilizada na alimentação de aves de postura comerciais até 0,93% de inclusão sem afetar o desempenho produtivo e na qualidade dos ovos.Submitted by Mario BC (mario@bc.ufrpe.br) on 2023-06-22T12:26:15Z No. of bitstreams: 1 Rita Brito Vieira.pdf: 916190 bytes, checksum: 749539c7ececafb7643898d3733636dc (MD5)Made available in DSpace on 2023-06-22T12:26:15Z (GMT).
