“…The ruminating behavior and masticating behavior of goats decrease with intravenous IPA infusions (Asato et al, 2001). We consider that IPA may have an important role in regulating the ruminating and masticating behavior of goats.…”

“…The concentration of glucose that tended to increase during IPA infusion may be related to increases in blood acetone concentration (table 2). Acetone is metabolized to glucose in cows (Black et al, 1972), and glucose concentration increases after intravenous IPA infusion (Asato et al, 2001).…”

“…In this study, increased ruminating behavior during intraruminal IPA infusion was associated with an increased IPA and acetone in the rumen and plasma. However, intraruminal acetone infusion (Kawamura et al, 1999) and intravenous IPA infusion (Asato et al, 2001) decrease ruminating behavior. So, increased rumen acetone and plasma IPA may not be the cause of increased ruminating behavior.…”

“…A decreased food intake during butyric acid infusion may be caused by increased ketones produced by a chemostatic mechanism (Simkins et al, 1967). The masticating behavior of goats decreases during intravenous acetone (Oshiro et al, 2000) and IPA (Asato et al, 2001) infusions. Montgomery and Baumgardt (1965) supported the hypothesis that ruminants adjust voluntary food intake in relation to the physiological demand for energy if the rumen fill or the rumen load do not limit their consumption.…”

Isopropyl alcohol (IPA), produced from acetone by rumen bacterial action, was infused into the rumen of three female goats kept in a climatically controlled experimental room during feeding to investigate the mechanism and roles of IPA in ruminating behavior (number of boli and ruminating time). The ruminating behavior measured by the number of boli, ruminating time, number of remastications, and remasticating time increased (p<0.05) with intraruminal IPA infusion. The concentrations of IPA and acetone in the rumen and the plasma significantly increased (p<0.05) during intraruminal IPA infusion. These data suggest that rumination receptors sensitive to IPA and acetone may be in an area such as the rumen epithelium and the brain stem where they can respond to metabolite levels.
