Resumo: Two experiments were conducted to evaluate the effects of inclusion of crude glycerin (CG) in the supplement (0, 70, 140, 210, and 280 g kg-1 dry matter (DM) of supplement) of Nellore cattle grazing tropical grasses during dry season. In Experiment 1, intake, digestibility, ruminal fermentation, and the rumen microbial profile were evaluated in two simultaneous 5 × 5 Latin squares, using 10 ruminally cannulated Nellore steers (408.8 ± 38.5 kg of body weight (BW)). In Experiment 2, cattle growth performance was evaluated in 50 young Nellore bulls (279.52 ± 16.3 kg of BW) distributed in a randomized complete block design. The increasing inclusion of CG did not affect intake ( P= 0.813), diet digestibility (P = 0.895), however linearly increased pH (P = 0.001), butyrate concentration (P < 0.001) and Fibrobacter succinogenes (P = 0.003) population. CG inclusion linearly decreased total ruminal volatile fatty acids (VFA) (P < 0.001), acetate concentration (P < 0.001) and quadratically affected (P = 0.009) acetate: propionate ratio. In experiment 2, the inclusion of CG quadratically affected DM intake (DMI) (P = 0.005), DM total-tract apparent digestibility (P < 0.001), linearly increased additional gain (P > 0.001), average daily gain (P > 0.001) and feed efficiency (P > 0.001). CG in the supplement of Nellore steers grazing tropical grass during dry season doesn’t affect intake and digestibility but alters ruminal fermentation, without negative effect on relative proportion of cellulolytic bacteria population. The increasing replacement of corn grain by CG in the supplement of pasture-raised growing Nellore bulls (up to 280g/kg DM) improved BW gain and consequently feed efficiency.

No experimento 1, o consumo, digestibilidade, fermentação ruminal e o perfil microbiano do rúmen foram avaliados em dois quadrados latinos 5x5 simultâneos, usando 10 novilhos Nelore canulados no rúmen (408,8 ± 38,5 kg de PC). No Experimento 2, o desempenho do crescimento do gado foi avaliado em 50 novilhos Nelore (279,52 ± 16,3 kg de PC) distribuídos em delineamento em blocos casualizados. A inclusão crescente de GB não afetou o consumo (P = 0,813), a digestibilidade da dieta (P = 0,895), mas aumentou linearmente o pH (P = 0,001), a concentração de butirato (P < 0,001) e a população de Fibrobacter succinogenes (P = 0,003). A inclusão de GB diminuiu linearmente os ácidos graxos voláteis totais (AGVs) no rúmen (P < 0,001), a concentração de acetato (P < 0,001) e afetou quadraticamente a relação acetato: propionato (p = 0,009). No experimento 2, a inclusão de GB modificou quadraticamente o consumo de matéria seca (CMS) (P = 0,005), a digestibilidade aparente total (P < 0,001), aumentou linearmente o ganho adicional (P > 0,001), o ganho médio diário (P > 0,001) e a eficiência alimentar (P > 0,001). GB no suplemento de novilhos Nelore pastejando gramíneas tropicais durante a estação seca não afeta a ingestão e digestibilidade, mas altera a fermentação ruminal, sem efeito negativo sobre a proporção relativa de bactérias celulolíticas. A crescente substituição do grão de milho por GB no suplemento touros Nelore em crescimento criados em pastagem (até 280g / kg de DM) melhorou o ganho de peso e consequentemente a eficiência alimentar.Universidade Estadual de Londrina2019-06-03T17:05:49Z2019-06-03T17:05:49Z2018-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVITO, E.
