Functional development of epithelial tissue of the reticulo-rumen in calves

Absorption and metabolism of longchain fatty acids by bovine rumen mucosa

“…The relative rates of substrate disappearance from the rumen of the M calf, versus that of the MHG calf, follow the same pattern as reported by Sutton (1962), in trials to study the absorption of acetic acid from the rumen of animals on similar diets. The decline in the concentration of oleic acid with time Sutton (1962). This might indicate that oleic acid is absorbed to some degree from the rumen of the 8-wk-old milk-fed calf.…”

“…Saliva entering the rumen affects the pH of the contents therein, and may also create problems in obtaining representative samples of rumen contents by failing to mix well with the test solution. Sutton (1962) noted that some animals were able to swallow saliva past the esophageal balloon and into the rumen as early as 16 weeks of age.…”

“…A rubber cannula, identical to that used by Sutton (1962) was then placed in the fistula immediately upon completion of the surgery.…”

“…However, the fate of the long-chain fatty acids in the rumen has received somewhat less attention. The absorption and metabolism of VFA have been reviewed thoroughly by Sutton (1962), and Hodson (1965) has recently reviewed the role of VFA in the ketogenic activity of the rumen mucosa. Therefore, these topics will be given only brief coverage here.…”

“…The Incubation procedures closely resembled those used previously in this laboratory by Sutton (1962) and by Hodson (1965).…”
