This study was conducted to determine the effects of four different dietary fat sources on performance, fatty acids composition of abdominal fat, thigh skin, breast and thigh muscle of broiler chickens. Soybean oil (SO), poultry grease (PG), beef tallow (BT) and a mixture of soybean oil with poultry grease (SPG 1 : 1) were used as fat source. A total 395, 4-day-old broilers were randomly assign...

A factorial design was used to study the effect of changes in broiler feed on the composition and consumer acceptability of chicken meat. One week before slaughter, 1.25% dietary fish oil was removed from the feed and replaced by other fat sources (animal fat or linseed oil) or we continued with fish oil, and diets were supplemented with Zn (0, 300, or 600 mg/kg), and Se (0 or 1.2 mg/kg as sodi...

Mammographic breast density is a significant risk factor for breast cancer. The present report analyzes the association of breast density and dietary factors in 1508 women in a historical cohort study of breast cancer families in Minnesota. Diet was assessed by a semiquantitative food frequency questionnaire. Percent breast density was estimated visually by a radiologist experienced in mammogra...

the objective of the present study was to investigate the effects of dietary l-arginine on performance, meat production and its chemical composition, carcass fat deposition, intestine morphology and blood parameters of ross broiler chickens during 46 days. in this experiment, 192 day old commercial female ross broiler chicks were used with 4 dietary treatments and 4 replications in a completely...

Two trials that utilized 356 yearling steers were conducted to evaluate the effects of fat sources (3.5% of diet dry matter) in steam-flaked milo finishing diets. Fats differed in fatty acid composition and level of free fatty acids. In Trial 1, soybean oil, tallow and yellow grease were compared to a nonfat control. Feeding fat increased (P less than .05) daily gain, feed efficiency, estimated...

The practice of “fat feeding” has become common in the dairy industry in a number of countries. There are several ideas as to how dietary lipids could influence reproductive performance. Highly saturated triacylglycerols (TAG), like palm oil, can increase milk yield but may aggravate negative energy balance and consequently impair fertility when fed during the first weeks postpartum. However, p...

OBJECTIVE To assess the effect of reduction or modification of dietary fat intake on total and cardiovascular mortality and cardiovascular morbidity. DESIGN Systematic review. DATA SOURCES Cochrane Library, Medline, Embase, CAB abstracts, SIGLE, CVRCT registry, and biographies were searched; trials known to experts were included. INCLUDED STUDIES Randomised controlled trials stating inten...
