A TOTAL of 28 crossbred wethers were used in two experiments to determine the digestibilty of hydrogenated tallow-, saturated fatty acidsand soybean oil-supplemented diets. Digestibility values for individual fats were determined by subtracting from total dietary lipid and fecal output the dietary and fecal lipids measured with basal diets. In the first experiment addition of 3% flaked, hydroge...

two hundred eighty days old male broiler chicks(ross strain) were randomly distributed into seven groups with four replicates (10 birds in each replicate) and were fed diets supplemented with different dietary fat sources.the results indicated that the different dietary treatments did not affect weight gain, feed intake and feed conversion ratio at 21 d (p>0.05). however, addition of dietary fa...

Thirty multiparous Holstein cows (29.8 ± 4.01days in milk; 671.6 ± 31.47 kg of body weight) were used in a completely randomized design to compare nutritional value of four fat sources including tallow, raw soybeans, extruded soybeans and roasted soybeans for 8 weeks. Experimental diets were a control containing 27.4 % alfalfa silage, 22.5% corn silage, and 50.1% concentrate, and four diets wit...

this experiment was conducted to evaluate the effects of turmeric powder (trp), tomato pomace (tp), fat sources (canola oil, soybean oil and tallow) on immune system and jejunum morphometric parameters of heat stressed broiler chickens. five hundred four one-d-old ross broiler were randomly distributed to 36 experimental units and 12 dietary treatments (3 replicates with 12 birds in each). the ...

An experiment was conducted to determine the effect of supplementing diets fed to growing pigs with fat sources differing in their composition of fatty acids on the apparent total tract digestibility (ATTD) of minerals. A diet based on corn, potato protein isolate, and 7% sucrose was formulated. Five additional diets that were similar to the previous diet with the exception that sucrose was rep...

The effects of dietary fats , consisting of different fatty acids, on body fat accumulation and uncoupling protein (UCP) in interscapular brown adipose tissue were studied in rats. Metabolisable energy in experimental diets based on safflower oil, soybean oil or beef tallow was measured strictly (experiment 1). Male Wistar rats were then meal-fed an isoenergetic diet for 8 weeks (experiment 2)....

An experiment was conducted to determine the interaction between fat source and xylanase supplementation on the performance, utilisation of energy and fat, and caecal microbiota counts in broiler starters fed wheat-based diets. The experimental design was 2×2 factorial arrangement of treatments, which included two fat sources (60 g/kg soybean oil or tallow) and two levels of enzyme supplementat...
