In connection with the problem of the well-known stability of statolith starch, some enzymes of starch metabolism have been investigated qualitatively in the root cap cells of Zea mays L. No activity of granule-bound UDPG- and ADPG-transglucosylase (EC 2.4.1.21) could be found. In the soluble enzyme
Feeding manufactured liquid diets to early-weaned pigs improves growth performance and reduces days to market weight compared with pigs receiving pelleted dry feed. Few alternative dietary ingredients are utilized in manufactured liquid diets other than byproducts of the dairy industry, especially
We tested the effect of dietary fat on the lipid composition and hydrolase activity of jejunal brush border membranes in piglets. Eighteen 5-wk-old piglets were divided into three groups and for 4 wk fed either an unsaturated low fat diet (3.2% corn oil), an unsaturated high fat diet (17.2% corn
EtOH (70%) extracts from the leaves of Eugenia uniflora were separated into six fractions with different polarity and molecular size, i.e. NP-1-NP-6. In an oral glucose tolerance test, NP-1 and 4 inhibited the increase in plasma glucose level. However, in an intraperitoneal glucose tolerance test,
For 1 wk, 3-mo-old male rats were fed a low-starch (5 cal%), high-fat (73 cal%, corn oil) diet followed by a high-glucose-polymer (70 cal%), low-fat (7 cal%, corn oil) or a middle-glucose-polymer (40 cal%), middle-fat (37 cal%, corn oil) diet. Other animals were fed similar diets but with starch or
An experiment was done to determine maltase, sucrase, isomaltase, and trehalase activities in mucosa of different segments of small intestines of young turkeys as influenced by age and diet. Two-day-old poults were fed diets containing no added fat [44.6% starch, 2.2% ether extract by weight (HC)],
BACKGROUND
Long-term feeding of fish oil (n-3) and corn oil (n-6) markedly enhances levels of lipid peroxidation within isolated rat enterocytes. The effect is 10-fold greater at the villus tip than in the crypt region, correlating with the distribution of deleterious oxidative systems (glutathione
