“…Felinski et al 1964). It is also possible that variations exist between species in the structure and composition of micelles in the intestine, and that these variations may be related to the relatively high intestinal pH, the low concentration of monoglycerides, and the high concentration of phospholipids in the intestine in sheep (Hofmann 1966;Bath and Hill 1967;Garton 1967;Lennox, Lough, and Garton 1968).…”

SummaryNormal sheep and sheep with fistulae of the bile duct or the thoracic duct were used to provide quantitative information on the movement of fatty acids into and out of the intestine. The operation used to gain access to the thoracic duct did not cause any significant alteration in the absorption of either [14C]tripalmitin injected into the rumen or [14C]palmitic acid injected into the duodenum. Normal sheep absorbed the major fatty acids oleic (92'1±1'3%), palmitic (87·3±5·0%), and stearic acids (93' 3± 1· 4%) with almost equal efficiency, and the absorption of labelled tripalmitin injected into the rumen did not alter as the intake of fatty acids increased from 12g/day (90·1±2·3%) to 44g/day (90·1±1·3%).An average of 6 g of fatty acids entered the duodenum each day in the bile, and an approximately equal amount entered from other endogenous sources. The rate of entry of fatty acids in the bile was increased by secretin and by infusion of bile into the intestine. Sheep deprived of bile absorbed 25± 1· 6% of labelled palmitic acid and slightly less of oleic and stearic acids but the transport of absorbed fatty acids in the lymph was negligible in the absence of bile.

“…Both galactose and glycerol are subsequently metabolized in the rumen to volatile fatty acids. Bath and Hill (1967) confirmed that complete hydrolysis of exogenous glyceridic lipids was effected in the rumen. Using rumen-fistulated animals, they were unable to detect mono-and diglycerides following a fat diet.…”

“…Hawke and Robertson (1964) had previously found hydrolysis intermediates (mono-and diglycerides) in the rumen after infusion of linseed oil. However, these results were explained in terms of over loading the rumen with triglyceride (Bath and Hill, 1967).…”

“…Lysolecithin then assumes the role of monoglyceride in micelle formation in the ruminant intestine (Bath and Hill, 1967;Leat and Harrison, 1969). Lennox and Garton (1968) fitted sheep with re-entrant cannulae in different parts of the small intestine to study absorption of long chain fatty acids.…”

The lipolysis and hydrogenation of lipids in the digestive tract of the sheep

Abstract: 1. The flow of digesta in the duodenum and the changes in the lipid composition of ruminal and duodenal digesta of sheep accustomed to receiving hay and oats, hay and palm oil and hay and tallow have been studied.
