Resumo: | The production and use of biodiesel in Brazil provide the development of a sustainable energetic source regarding environmental, economical and social aspects. Biodiesel production generates residues such as glycerin, and sustainable measures to reuse these wastes need to be developed in order to protect the environment. Research about the addition of glycerin in animal feeding have been conducted and are feasible due to the possibility of reducing the diet costs because of the great product supply on the market. This work aimed at evaluating the metabolic and physiologic parameters of cats receiving glycerin in their diets. The experiment was conducted in a cattery at the Animal Science Department from the Federal University of Lavras. A total of 30 adults cats, males and females of mixed breed weighting 3.52 ± 0.67 kg, were distributed in a completely randomized design with five treatments (control and substitution of 4, 8, 12 and 16% of glycerin), during 15 days. The animals received 300 mL of water daily in order to determine water consumption. Statistical analyses were conducted using the SISVAR computational program and averages of the treatments were compared by Dunnet test. According to the results, there was no significant difference (P>0.05) for the following coefficients: apparent digestibility of dry matter, mineral materials, crude protein, ether extract and apparent metabolizable energy in the dry matter of diets. There was a significant increase (P<0.05) of the apparent digestibility of dry matter in the diet with 12% of substitution of glycerin. Serum concentrations of glucose, total cholesterol, HDL, LDL, VLDL, AST and ALT and creatinine levels were not affected by the inclusion of glycerin (P> 0.05). However, there was a significant reduction of the urea blood concentration (P<0.05). The urinal density and pH values did not change significantly (P>0.05). The substitution of 12% of glycerin presented, in general, the best results of the variables herein studied. However, substitutions up to 16% did not affect the evaluated parameters. The glycerin used in this work presents methanol levels higher than the safety levels set by MAPA. Nevertheless, there were no metabolic or physiologic alterations in cats during the glycerin administration. |

A produção do biodiesel gera resíduos, como a glicerina, e medidas sustentáveis de reutilização destes coprodutos precisam ser desenvolvidas para preservação do meio ambiente. Pesquisas sobre a adição de glicerina na alimentação animal foram impulsionadas pela possibilidade de reduzir os custos da dieta em razão da grande oferta do produto no mercado mundial Objetivou-se avaliar parâmetros metabólicos e fisiológicos de gatos recebendo dieta com glicerina. O experimento foi realizado no gatil do Departamento de Zootecnia da Universidade Federal de Lavras, utilizando 30 gatos adultos, machos e fêmeas, sem raça definida, com peso de 3,52 ± 0,67Kg, distribuídos em um delineamento inteiramente casualizado com cinco tratamentos (controle e substituição de 4, 8, 12 e 16% de glicerina) durante 15 dias. Os animais receberam 300 ml de água por dia a fim de determinar o consumo hídrico. As análises estatísticas foram realizadas, por meio do programa computacional SISVAR, em que as médias dos tratamentos foram comparadas pelo teste de Dunnet. Não houve diferença significativa (P>0,05) para os coeficientes de digestibilidade aparente da matéria seca, matéria mineral, proteína bruta, extrato etéreo e energia metabolizável aparente na matéria seca das dietas. Ocorreu um aumento significativo (P<0,05) da energia digestível aparente na matéria seca na dieta com 12% de substituição de glicerina. As concentrações séricas de glicose, colesterol total, HDL, LDL, VLDL, AST e ALT e creatinina não foram influenciadas pelo nível de inclusão de glicerina (P>0,05), porém houve redução significativa das concentrações sanguíneas de ureia (P<0,05). Os valores da densidade e o pH urinário não apresentaram mudanças significativas (P>0,05). A substituição de 12% de glicerina apresentou, no geral, melhores resultados das variáveis analisadas. No entanto, a substituição de até 16% de glicerina não resultou em prejuízos nos parâmetros avaliados. A glicerina utilizada continha níveis de metanol muito acima dos valores de segurança estabelecidos pelo MAPA e, mesmo assim, não causou alterações metabólicas e fisiológicas nos gatos durante o tempo de administração da glicerina.Universidade Federal de LavrasPrograma de Pós-Graduação em ZootecniaUFLAbrasilDepartamento de ZootecniaSaad, Flávia Maria de Oliveira BorgesFraga, Antônio CarlosLara, Leonardo BoscoliLacerda, Roberta Freitas2016-04-13T20:33:29Z2016-04-13T20:33:29Z2016-04-132016-02-26info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfLACERDA, R.
