Resumo: | The aim was to evaluate the centesimal composition and fatty acids profile of longissimus dorsi of wethers fed diets with increasing levels (0; 2.65; 5.33 e 8.06% in dry matter) of crude glycerin (CG). Were used 20 crossbred, castrated lambs Dorper x St. Ines, with 24 ± 2.0 kg of weight, housed in individual pens. The experimental design was completely randomized with four treatments and five replications. Diet samples were collected to fatty acids profile analyses. After 84 days of assessment and data collection, the animals were slaughtered. Longissimus dorsi samples were collected and frozen for subsequent analysis of fatty acids by gas chromatography. There was no effect of treatments on the ash content and protein, however, there was influence (P<0.05) on the lipid content and moisture. The fatty acids which had the highest percentages in meat were stearic and oleic acids respectively. These acids were not influenced (P>0.05) by increasing levels of crude glycerin in the diet. There was decreased linear effect (P<0.05) for palmitic fatty acid (16:0) and quadratic effect (P<0.05) for myristic acid (14:0) as a function of increasing glycerin levels in diet. The glycerin addition in the diets affected quadratically (P<0.05) the total polyunsaturated fatty acid (PUFA) and omega 6. There was increasing linear effect (P<0.05) for the sum of total conjugated linoleic acid (CLA) and PUFA / SFA ratio. Were not affected by increasing levels of glycerin in the diet the total saturated fatty acids (SFA), monounsaturated fatty acids, omega 3 family and 6 omega/omega 3 ratio. The inclusion of glycerin yielded changes in proximate composition and fatty acid profile of the meat, but these changes did not alter the meat quality. |

Foram utilizados 20 cordeiros mestiços Santa Inês x Dorper, machos castrados, com 24 ± 2,0 kg e alojados em baias individuais. O delineamento utilizado foi inteiramente casualizado, com quatro tratamentos e cinco repetições. Amostras das dietas ofertadas foram coletadas para avaliar a composição de ácidos graxos. Após 84 dias de avaliação e coleta de dados, os animais foram abatidos. As amostras do longissimus dorsi foram coletadas e congeladas para posteriores análises de ácidos graxos por cromatografia gasosa. Não foi observada influência dos tratamentos sobre os teores de cinzas e proteína, porém, houve influência (P<0,05) sobre os teores de lipídios e umidade. Os ácidos graxos que obtiveram maiores porcentagens na carne foram os ácidos oleico e esteárico, respectivamente. Estes ácidos não foram influenciados (P>0,05) pelos níveis crescentes de glicerina bruta na dieta. Houve efeito linear decrescente (P<0,05) para o ácido graxo saturado palmítico (16:0) e efeito quadrático (P<0,05) para o ácido graxo mirístico (14:0) em função dos níveis crescentes de glicerina na dieta. A adição de glicerina na dieta influenciou de forma quadrática (P<0,05) o total de ácido graxo poliinsaturado (AGPI) e ômega 6. Houve efeito linear crescente (P<0,05) para o somatório total do ácido linoleico conjugado (CLA) e para razão AGPI/AGS. Não foram influenciados pelos níveis crescentes de glicerina na dieta o total de ácidos graxos saturados (AGS), ácidos graxos monoinsaturados, ácidos da família ômega 3 e para razão ômega 6/ômega 3. A inclusão de glicerina proporcionou alterações na composição centesimal e perfil de ácidos graxos no longissimis dorsi, porém, essas modificações não alteraram a qualidade da carne.
