Resumo: The aim was to evaluate the economic viability of increasing levels of crude glycerin (CG) in diets for finishing lambs. The trial was carried out at Southwest State University of Bahia, Itapetinga-BA. Twenty five crossbred, Santa Inês x Dorper, with 24 ± 2,0 kg, were housed in individual pens. The experimental design was completely randomized with five treatments and five replications. Treatments consisted of increasing levels of dietary CG (0, 2.65, 5.33, 8.06 and 10.84%) and the roughage used was the Tifton 85 hay. Diets were formulated to meet the nutritional requeriments, aiming a gain of 200 g day-1. The analysis was based on use of economic indicators Net Present Value (NPV) and Internal Rate of Return (IRR). The animals dry matter intake decreased linearly (P<0.05) as the glycerin levels increased in the diet. However, there was no effect (P>0.05) on performance and meat production results. None of the treatments showed economic viability.

O experimento foi desenvolvido na Universidade Estadual do Sudoeste da Bahia, Itapetinga-BA. Foram utilizados 25 cordeiros mestiços Santa Inês x Dorper, machos castrados, com 24 ± 2,0 kg, alojados em baias individuais. O delineamento utilizado foi inteiramente casualizado, com cinco tratamentos e cinco repetições. Os tratamentos consistiram de níveis crescentes da GB na dieta (0; 2,65; 5,33; 8,06 e 10,84%) e o volumoso utilizado foi o feno de Tifton 85. As dietas foram calculadas para atender às exigências nutricionais, visando um ganho de 200 g/dia. A análise foi realizada a partir da utilização dos indicadores econômicos como o Valor Presente Líquido (VPL) e Taxa Interna de Retorno (TIR). O consumo de matéria seca dos animais diminuiu linearmente (P<0,05) com o aumento dos níveis de glicerina na dieta, porém, não foi observada influência (P>0,05) para o desempenho e, consequentemente, para a produção de carne. Nenhum dos tratamentos apresentou viabilidade econômica. UEL2015-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1550010.5433/1679-0359.2015v36n1p443Semina: Ciências Agrárias; Vol. 36 No. 1 (2015); 443-452Semina: Ciências Agrárias; v. 36 n. 1 (2015); 443-4521679-03591676-546Xreponame:Semina.
