A feeding trial was conducted to evaluate the effects of diets contaminated with deoxynivalenol (DON on the performance of broilers and on the electro-physiological parameters of the gut. The control group was fed the starter and finisher diets without addition of DON. Another group of broilers was fed the starter and finisher diets with 10 mg/kg DON,(More)
Seventy-two 26-wk-old Single Comb White Leghorn laying hens were randomly assigned to 36 cages (2 per cage) in a 3-orthogonal 4 x 4 latin square, with the fourth row suppressed, to assess the effect of feeding refined seal blubber oil (SBO, containing 22.2% omega-3 fatty acids) on the fatty acid composition and position in the egg yolk lipids. The(More)
The level of free fatty acids in intact tissues has been found to be low but is known to rise in proportion to the extent of autolysis. Therefore, the high levels of free fatty acid reported in the cardiac lipids of rats fed rapeseed oil were reinvestigated using two different procedures for homogenization. Quick freezing and pulverization at dry ice(More)
Mastitis is not only a major cause of economic losses to the dairy industry but also a major problem in ensuring the quality and safety of the milk, associated with high somatic cell counts and residues of antibiotics used for treatment. One innovative approach to protection against mastitis is to stimulate the animal's natural defense mechanisms.(More)
A total of 384 Single Comb White Leghorn cockerels of the Hyline strain were fed either a basal (control) diet containing no added oil or a diet supplemented with 20% by weight of soybean oil, rapeseed oil from cultivars Tower, Candle, a mixture of Echo and Arlo high erucic acid rapeseed (HEAR), or R-500. Levels of erucic acid (22:1) in the rapeseed diets(More)
A total of 2000 commercial chickens (1000 males and 1000 females) were used in an exploratory experiment designed to estimate the effect of two daily feed denial treatments (8 and 12 hr) extended from either 8 to 21 days or 15 to 28 days of age. Mortality was unaffected by these treatments. Body weight at 28 days was reduced, and feed conversion was(More)
Studies were carried out on Sprague-Dawley (SD) and Chester Beatty (CB) rats to determine whether the difference in incidence of myocardial lesions can be related to dietary factors and parameters known to be affected in SD rats fed rapeseed oils. The two strains of young, male rats were fed diets which contained 20% by weight of either corn, LEAR (low(More)
Sterol esters were transesterified within 1 hr using either acid or base catalysts. Acid-catalyzed methanolysis of sterol esters with HCl, H2SO4, or BF3 leads to the formation of two artifacts derived from the sterol portion of the molecule; they were identified as dehydrated and methoxylated derivatives of sterols. These two artifacts were not produced(More)
A total of 4,800 broiler chickens of one commercial genotype were used to study the interrelated effects of two lighting treatments (green fluorescent vs. incandescent), three weekly rates of ambient temperature decline (4.5, 3.5, 2.0 C), and starter/finisher diets with four levels of dietary energy (3,100/3,300; 3,000/3,200; 2,900/3,100; and 2,800/3,000(More)
