Impact of increased bean residue levels on the feed efficiency and ingestive behaviour of sheep (original) (raw)

Biological Rhythm Research, 2019

Abstract

ABSTRACT The objective of this study was to evaluate the effect of including common-bean residue in diets for feedlot sheep on feed efficiency and on ingestive behaviour of sheep. Treatments consisted of the inclusion of 0.0%, 11%, 22% and 33% of the common-bean residue (dry matter basis) in the experimental diets, which corresponded to the substitution levels of 0.0%, 33.3%, 66.7%, and 100.0% of cottonseed cake for the beanresidue. The inclusion of common bean residue did not change (P > 0.05) the NDF intake by the sheep, whose mean values were 358.37 g animal-1 day-1, 1.07% BW, and 14.81 g kg-1 BW0.75. There was a linear decreasing effect (P < 0.05) for the total chewing time, with a reduction to 94.48 min day-1 at the maximum inclusion level (33%) of bean residue in the diet, in relation to the treatment without this by-product (280.17 min day-1). A decreasing linear effect (P < 0.05) was observed for the number of ruminatedboluses per day, where it reduced by 0.66 percentage units for each 1% inclusion of the bean residue. Bean processing residue can be substituted for cottonseed cake in the concentrate fed to sheep, at levels of up to 33%.
