Functional foods are foods enriched with single ingredients, which influence 1 or more functions of the consumer in a favorable way, exceeding the effects of normal adequate nutrition. Consumers can expect health benefits from these products. The production of functional poultry meat is a promising future perspective, although the market share of such products will be small. The objective of th...

Excessive intake of trans-fatty acids increases the risk of cardiovascular disease. Much attention is drawn to the consumption of trans-fatty acids worldwide, and regulations for trans-fatty acids are instituted in several countries. Precise and convenient methods for determination of trans-fatty acid level are required, but there is no standard method using capillary Gas Chromatography in Japa...

A 111-d finishing study evaluated animal growth and carcass characteristics using 138 steers (366 kg) in a randomized complete block design with a 2 x 3 factorial arrangement of treatments. The dietary treatments consisted of no supplemental fat or 3.5% tallow or soybean oil soapstock (SS) fed with .6% and .9% dietary Ca. Fat increased DMI (P less than .05) but interacted with Ca level (P less ...

The aim of this study was to evaluate the organogelation potential tallow fat (TF) and partially hydrolyzed (HTF) against saturated monoglyceride (MG) a + diglyceride mixture (MDG) as organogelators. TF itself created oleogel at 30% addition level, while HTF, MG MDG oleogels were prepared 10% levels. Fatty acid composition data showed that HTF (HTFO) quite similar those oleogels. Solid content,...

The effects of beef tallow and cocoa butter, two fats with a high stearic acid content (C18:0), on serum lipid and lipoprotein concentrations were compared with the effects of butter fat and olive oil in 10 middle-aged men. Liquid-formula diets containing 40% of the calories from the test fat were fed in random order for 3 wk each, with lipoprotein concentrations measured on the last five days....

The objective of this study was to determine if the length of chop of processed corn silage influences the impact of supplemental fat on rumen fermentation and performance of dairy cows. We hypothesized that increasing forage particle length may alleviate the interference of fat on rumen fermentation. Sixteen Holstein cows averaging 120 d in milk were used in a replicated 4 x 4 Latin square des...

Feed represents over 65 percent of the cost for poultry production. Fast-growing and high-producing poultry are fed high calorie and high protein maize-soybean-based diets. Considering the high demand for maize and other oil crops for biofuel production, finding alternative sources of energy could reduce production costs. Camelina sativa is an oilseed crop of the Brassica family that is emergin...

Thirty-six castrated male growing pigs were used to study the effect of dietary beef tallow (BT) versus sunflower oil (SO) on meat quality and fatty acid composition of various tissues. The diets used contained either 5% (w/w) of the variable fat source. The fat type had no significant effect on carcass traits (carcass weight, back-fat thickness, fat-lean ratio) and meat quality (colour, pH(1),...

Seventy-two pregnant ewes were al lot ted to three ration t reatment groups: 1) Control: corn silage and alfalfa pellets; 2) Tallow: corn silage, alfalfa pellets and protected tallow; 3) Polyunsaturated (P/S): corn silage and protected soybean and sunflower seeds. Diet influenced plasma glucose and linoleic acid content of esterified, but not of non-esterified, fat ty acids in ewe plasma. Propo...

Thirty-six castrated male growing pigs were used to study the eVect of dietary beef tallow (BT) versus sunXower oil (SO) on meat quality and fatty acid composition of various tissues. The diets used contained either 5% (w/w) of the variable fat source. The fat type had no signiWcant eVect on carcass traits (carcass weight, back-fat thickness, fat-lean ratio) and meat quality (colour, pH1, pHU, ...
