The Eating and Rumination Behaviour in Sheep Fed the Silages Made from the Fibrous Residues of Broad Bean (Vicia faba L.) and Lucerne (Medicago sativa L.) with Timothy (Phleum pratense L.) Hay

The Eating and Rumination Behaviour in Sheep Fed the Diet of Silage Made from Fibrous Residue Left after the Extraction of Ladino Clover (Trifolium repense L. var. giganteum) Leaf Protein with Timothy (Phleum pratense L.) Hay

“…As described in the previous report12), the volume (not weight) and/or bulk of feed ingested could also function as an another stimulus to raise rumination after eating, and then the difference in the lag time between silage feeding and hay feeding should be partially due to a difference in the bulk of feed in both experiments, even if the feeding level as weight of dry matter eaten (% of body weight of animal) is almost the same. From the results obtained in this study and the previous experiments6, 8,13), it can be concluded that a stimulus to the mechanoreceptor on the rumen wall is a more important factor in the initiation after eating, as compared with that of the chemo-receptor.…”

The effect of ruminal infusion of acetic, propionic and butyric acids on eating, rumination behaviour and feed utilization in sheep fed on ureasupplemented roughage

“…Particle size reduction through re-mastication of the feed improves rumen microbial and fermentation activities (Welch and Smith, 1969). Rumination behaviour is closely related to the amount of feed ingested (Gordon, 1965; and is influenced by changes in physical properties and/or chemical composition of feed ingested (Gordon, 1958;Fujihara, 1980;Fujihara and Nakao, 1990a;Mawuenyegah et al, 1997). Rumination is initiated by the presence of ruminal ingesta by chemical and/or physical stimuli to receptors in the rumen wall (Fujihara et al, 1989).…”
