Ruminal Epithelium

The objectives of this study were to determine the effect of an increase in diet fermentability on 1) the rate and extent to which short-chain fatty acid (SCFA) absorption pathways adapt relative to changes in Na+transport, 2) the epithelial surface area (SA), and 3) the barrier function of the bovine ruminal epithelium. Twenty-five Holstein steer calves were assigned to either the control diet (CON; 91.5% hay and 8.5% supplement) or a moderately fermentable diet (50% hay; 41.5% barley grain (G), and 8.5% supplement) fed for 3 (G3), 7 (G7), 14 (G14), or 21 days (G21). All calves were fed at 2.25% body weight at 0800. Calves were killed (at 1000), and ruminal tissue was collected to determine the rate and pathway of SCFA transport, Na+transport and barrier function in Ussing chambers. Tissue was also collected for SA measurement and gene expression. Mean reticular pH decreased from 6.90 for CON to 6.59 for G7 and then increased (quadratic P < 0.001). While effective SA of the ruminal epithelium was not affected ( P > 0.10) by dietary treatment, the net Na+flux increased by 125% within 7 days (quadratic P = 0.016). Total acetate and butyrate flux increased from CON to G21, where passive diffusion was the primary SCFA absorption pathway affected. Increased mannitol flux, tissue conductance, and tendencies for increased expression of IL-1β and TLR2 indicated reduced rumen epithelium barrier function. This study indicates that an increase in diet fermentability acutely increases Na+and SCFA absorption in the absence of increased SA, but reduces barrier function.

This study examined the lipid content and short chain fatty acid composition of fleece samples collected from Cashmere goat (Capra hircus laniger) bucks at various times throughout the year. Fleece samples from does and gonadectomised goats were also analysed at one time during the breeding season for comparison. Lipid was extracted with chloroform/methanol azeotrope, saponified, and analysed for short chain fatty acids (C2-Clo) by gas chromatography and gas chromatography/mass spectrometry. Bucks had increased amounts of lipid and ethyl-branched fatty acids in fleece samples shorn from March to September, compared with fleece samples shorn in November and January. The increases in the amounts of lipid and ethyl-branched fatty acids corresponded with the breeding season and the period when the buck odour was increased. This supports the assumption that ethyl-branched fatty acids may be a pheromone in goats.
