Resumo: | Voluntary consumption (VolC) and ingestive behaviour (IB) of lambs fed diets containing different percentages (0.0; 7.5; 15.0 and 22.5%) of babassu mesocarp bran (I-BMB) were evaluated. The trial was at the Federal University of Tocantins, Campus de Araguaína-TO. Twenty lambs were evaluated using a completely randomized design, and five replications were performed. VolC data was obtained by measuring total volumes of both food supplied and food remaining after feeding. IB was evaluated throughout two, non-consecutive 24-h periods, with observations were recorded every five minutes that described the following behavioural variables: resting (REST), rumination (RUM), intake (INT) and chewing (CHEW). The particle size was also measured using a Penn State particle separator. All VolC parameters (dry matter intake, DMI; crude protein intake, CPI; neutral detergent fibre intake, NDFI; and acid detergent fibre intake, ADFI) increased linearly with I-BMB intake. I-BMB consumption did not interfere with water intake, nor did it affect I-BMB did not affect the duration of DMI, NDFI and ADFI. However, linear increases of rumination and chewing activities associated with DMI, NDFI and ADFI were observed as I-BMB levels increased. In summary, effects of inclusion I-BMB in diets of lambs included increased voluntary consumption, and reduced rumination and chewing, but not ingestion, efficiency. When economically favorable, these data suggest that inclusion of up to 22.5% I-BMB within balanced diets should be applied. |

O local do ensaio foi a ovinocaprinocultura da Universidade Federal do Tocantins, Campus de Araguaína-TO. Foram utilizadas 20 borregas distribuídas em delineamento inteiramente casualisado, com cinco repetições. O CVol foi realizado pela mensuração do total de alimento fornecido e das sobras. Já o CI foi avaliado em dois períodos de 24 horas em dias não consecutivos, com observações de cinco em cinco minutos sendo as variáveis comportamentais: ócio (O), ruminação (R), ingestão (I) e mastigação (M). Mensurou-se também o tamanho de partícula com separador de partículas modelo Penn State. Foi observado aumento linear crescente com a I-FMB para todos os parâmetros de CVol estudados (consumo de matéria seca - CMS, consumo de proteína bruta - CPB, consumo de fibra em detergente neutro - CFND e consumo de fibra em detergente ácido - CFDA) em todas as unidades (g dia-1 animal-1, % do peso vivo (PV), g kg-0,75). A I-FMB não interferiu na ingestão de água de borregas. A I-FMB não afetou o tempo em ingestão por CMS, CFDN e CFDA. No entanto, a I-FMB aumentou linearmente as atividades ruminação e mastigação em função do CMS, CFDN e CFDA. A I-FMB na dieta de borregas aumenta o consumo voluntário de ovinos e influência de forma negativa na eficiência de ruminação e mastigação, sem prejudicar eficiência de ingestão. Quando economicamente favorável recomenda-se a inclusão de até 22,5 % de FMB em dietas balanceadas.UEL2020-08-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3846510.5433/1679-0359.2020v41n5supl1p2335Semina: Ciências Agrárias; Vol. 41 No. 5supl1 (2020); 2335-2348Semina: Ciências Agrárias; v. 41 n. 5supl1 (2020); 2335-23481679-03591676-546Xreponame:Semina.
