an experiment was conducted to study the effects of an emulsifier (glycerol polyethylene glycol ricinoleate: gpgr) and different sources of fat on the performance of khaki campbell ducks. ducks were assigned into five groups with three replicates (10 ducks/replicate) in each group. treatments were a control diet (c1: without added oil and emulsifier), control diet added with 2% soybean oil (c2)...

background: nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. objective: the present study explores the chemical constitution and antioxidant activity of leaf extract of hyssopus officinalis l. and extract of aerial ...

introduction high-producing dairy cows require large amounts of concentrates that are rich in energy and crude protein to meet their nutrient requirements. cereal grains and oil supplements are commonly used for increasing energy density of diets fed to high-producing dairy cows. dietary grain source (barley vs. corn) and oil supplement (soybean- vs. fish oil) resulted in varied dry matter inta...

Soybeans are very versatile, both as a food product and an ingredient in many industrial products. The oil produced by soybeans is contained within many foods we eat every day. Natural soybean oil contains several essential fatty acids that our body needs to work prop‐ erly, including linoleic and linolenic acids. However, much of the soybean oil consumed in many parts of the world has been par...

Background: Previously, we showed that vegetable oil is necessary for carotenoid absorption from salad vegetables. Research is needed to better define the dose effect and its interindividual variation for carotenoids and fat-soluble vitamins.Objective: The objective was to model the dose-response relation between the amount of soybean oil in salad dressing and the absorption of 1) carotenoids, ...

BACKGROUND Distiller's dried grains with solubles (DDGS) and soybean meal were used as the substrates for the production of polyunsaturated fatty acids (PUFA) in solid-state fermentation (SSF) by Mortierella alpine. These fermented products were fed to laying hens. PUFA enrichment from chicken breasts was studied. METHODS The maximum productivity of PUFA was achieved under optimized process c...

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

This study was conducted to investigate the effects of dietary coconut oil as a medium-chain fatty acid (MCFA) source on performance, carcass composition and serum lipids in male broilers. A total of 540, one-day-old, male Arbor Acres broilers were randomly allotted to 1 of 5 treatments with each treatment being applied to 6 replicates of 18 chicks. The basal diet (i.e., R0) was based on corn a...

When and under what circumstances domestication related traits evolved in soybean (Glycine max) is not well understood. Seed size has been a focus of archaeological attention because increased soybean seed weight/size is a trait that distinguishes most modern soybeans from their ancestors; however, archaeological seed size analysis has had limited success. Modern domesticated soybean has a sign...
