Consumo e digestibilidade da matéria seca de fenos de braquiária decumbens e amendoim forrageiro em ovinos estimados por meio de n-alcanos

Abstract: RESUMO -O experimento foi realizado com os objetivos de avaliar a técnica de n-alcanos para estimar o consumo e a digestibilidade da MS em ovinos e definir a estratégia de coleta de fezes e os alcanos internos a serem utilizados no cálculos.Vinte ovinos foram distribuídos em delineamento inteiramente casualizado e alimentados com dietas formuladas com diferentes proporções de amendoim forrageiro (Arachis pintoi Koprov & Gregory cv. Amarillo) e braquiária decumbens [Urochloa decumbens (Stapf), Webster] (0, 15, … Show more

“…Regarding apparent digestibility, Fukumoto et al [ 11 ] concluded that only one daily faecal sample collection between 9 h and 13 h is needed to estimate the digestibility of nutrients in sheep fed ad libitum. The use of internal markers, such as the acid-insoluble ash (AIA) technique, to determine the digestibility of nutrients from faecal samples collected during the day has been uniformly accepted [ 12 ], assuming that AIA is a natural component of feeds that is expected to flow with the digesta through the gastrointestinal tract of the animal.…”

“…The supply of an external indicator to the animal, i.e. a non-diet substance, represents an important source of variation in results (FUKUMOTO et al, 2007) due to possible losses of the indicator at the time of its administration or due to the stress caused to the animal due to the management of supplying it by esophageal route. Chromic oxide (Cr 2 O 3 ) have been the most used external indicator in studies of consumption and digestibility (MOURA et al, 2013) to estimate fecal production.…”
