the aim of this study was to determine effects of different fatty acid profiles on rumen digestion coefficients, some of rumen metabolism parameters and rumen microbial populations. different oils were used as source of fatty acids such as, oleic, linoleic, linolenic, dha and epa. palmitic acid supplemented from a commercial product (bergafat t-300) containing high palmitic acid percentage. res...
Effect of sesame oil feeding on performance, plasma lipids and ruminal fermentation of growing lambs
Background: In recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. OBJECTIVES: This study was conducted to determine the effect of increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing Chal lambs. METHODS: Eighteen male ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...

nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Two experiments were conducted to determine the effects of several essential oil active compounds on rumen microbial fermentation. In the first experiment, 4 doses (5, 50, 500, and 5,000 mg/L) of 5 essential oil compounds were evaluated using in vitro 24-h batch culture of rumen fluid with a 60:40 forage:concentrate diet (18% crude protein; 30% neutral detergent fiber). Treatments were control ...
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...
