Resumo: | This study was conducted to evaluate the nutrients intake and the productive performance ofdairy cows and steers fed diets containing glycerol. The animals were distributed in a completely randomized design with factorial arrangement 4 glycerol levels (0, 6, 12 and 24%) x2sexes (steers and cows) and three replications. The consumption of dry matter (DM) crude protein (CP) and non-fiber carbohydrates (NFC) were not affected by inclusion of glycerol in the diets of cows and steers.However, there was a linear decrease in the consumption of neutral detergent fiber (NDF) (g/kg BW) for cows, but it did not affect the consumption of NDF and ethereal extract (EE) for steers when expressed in kg/day, but showed a quadratic response to NDF intake expressed as%BW and a linear decrease for the consumption of EE expressed in g/kgBW0.75 and %BW. The cows showed a higher intake of DM, CP, NDF, NFC, expressed in kg/day, than the steers, when the diets included 6 and 12% glycerol and higher intakes of DM, NDF and NFC, expressed in g/kg/BW0.75, when diet included 6% glycerol. The daily weight gain was not affected by the inclusion of glycerol. We concluded that glycerol can be included up to 24% of total DM of diets ofdairy steers and cows without compromising animal performance.KEYWORDS: biodiesel byproducts; crude glycerin; nutritional value. |

Os animais foram distribuídos em um delineamento experimental inteiramente casualizado, com arranjo fatorial de 4x2 (0, 6, 12 e 24% de glicerol x sexos – vacas e novilhos) e três repetições. Foi observado que os consumos de matéria seca (MS), proteína bruta(PB) e carboidratos não fibrosos (CNF)não foram afetados pela inclusão do glicerol às dietas de vacas e novilhos. Houve diminuição linear no consumo de fibra em detergente neutro (FDN) (g/kg de PC) para as vacas; no entanto, os consumos de FDN e extrato etéreo (EE) dos novilhos não foram afetados quando expressos em kg/dia, mas apresentaram comportamento quadrático para o consumo de FDN expresso em %PC e diminuição linear para o consumo deEE expressos em g/kgPC0,75 e %PC. As vacas apresentaram maior consumo de MS, PB, FDN, CNF expressos em kg/dia que os novilhos, quando se incluiu 6 e 12% de glicerol às dietas, e maior consumo de MS, FDN e CNF expressos em g/kg/PC0,75, quando se incluiu 6% glicerol às dietas. O ganho de peso diário não foi afetado pela inclusão do glicerol. Conclui-se que o glicerol pode ser incluído em até 24% da MS total das dietas de novilhos e vacas de aptidão leiteira sem comprometer o desempenho dos animais.
