THE SUPPLY OF PECTIN IN BOVINES AND ITS EFFECT ON BLOOD CHOLESTEROL AND FAT EXCRETION

Abstract

Objective: Evaluating the effect of pectin supplement in the diet on the concentration of blood cholesterol and the excretion of total fat in feces of bovines.

Design / methodology / approach: Four Holstein calves were used with cannulas in the rumen and duodenum, and low (0.004%), medium (0.02%) and high (0.01%) pectin doses were infused by duodenal route.

Results: The blood cholesterol concentration decreased 15.6, 18 and 27% when the pectin doses were increased. Total fat excretion was higher with all doses of pectin (0.3 (control) vs. 1.9, 1.3, 1.7, P <0.0001).

Study limitations / implications: There is interest in evaluating the supply of pectin in bovines, with the purpose of reducing the concentration of circulating cholesterol and improving the quality of lactic and meat products intended for consumers.

Findings / Conclusions: The pectin dosages decreased the blood cholesterol and the absorption of total fat in feces.
