Crude glycerin, the main by-product of biodiesel production, can replace dietary energy
sources, such as corn. The objective of this study was to evaluate the inclusion of up to 30%
of crude glycerin in dry matter (DM) of the total diets, and its effects on meat quality parameters
of feedlot Nellore bulls. Thirty animals (227.7 ± 23.8 kg body weight; 18 months old)
were housed in individual pens and fed 5 experimental diets, containing 0, 7.5, 15, 22.5 or
30% crude glycerin (DM basis). After 103 d (21 d adaptation) animals were slaughtered and
the Longissimus muscle was collected. The characteristics assessed were chemical composition,
fatty acid profile, cholesterol, shear force, pH, color, water-holding capacity, cooking
loss and sensory properties. The increasing inclusion of crude glycerin in the diets did
not affect the chemical composition of the Longissimus muscle (P > 0.10). A quadratic effect
was observed when levels of crude glycerin were increased, on the concentration of pentadecanoic,
palmitoleic and eicosenoic fatty acids in meat (P < 0.05), and on the activity of the
delta-9 desaturase 16 and delta-9 desaturase 18 enzymes (P < 0.05). The addition of crude
glycerin increased the gamma linolenic fatty acid concentration (P < 0.01), and altered the
monounsaturated fatty acids in Longissimus muscle of animals (Pquad. < 0.05). Crude glycerin
decreased cholesterol content in meat (P < 0.05), and promoted higher flavor score and
greasy intensity perception of the meat (P < 0.01). The inclusion of up to 30% crude glycerin
in Nellore cattle bulls`diets (DM basis) improves meat cholesterol and sensory attributes,
such as flavor, without affecting significantly the physical traits, the main fatty acid concentrations
and the chemical composition. MenosCrude glycerin, the main by-product of biodiesel production, can replace dietary energy
