Methane emission factors are lacking from different livestock species in various production states fed varying diets. The objectives of the present study were to measure effects of physiological state, silage type, and supplemental NDF on DMI, DM digestibility (DMD), and methane emissions of lactating and dry dairy cows using two 4 × 4 Latin squares (5-wk periods) with four lactating (114 DIM ±...

Background and purpose: Determination of heavy metals in oils is necessary to establish quality standards on a country level. This study aimed to determine of heavy metal contents (Cr, Ni, As, Cd, Hg, Pb, Sb, Sn, Sr, Al) in 12 seed oil samples in Iran by inductively coupled plasma-optical emission spectrometry (ICP-OES). Materials and Methods: The concentrations of heavy metal were determined b...

An increasing amount of evidence supports pleiotropic metabolic roles of the cannibinoid-1 receptor (CB1R) in peripheral tissues such as adipose, liver, skeletal muscle and pancreas. To further understand the metabolic consequences of specific blockade of CB1R function in peripheral tissues, we performed a 10-week-study with an anti-sense oligonucleotide directed against the CB1R in diet-induce...

Two experiments were conducted to evaluate effects of barley grains particle size on ruminal pH and ammonia concentration of rams (experiment 1) and carcass characteristics (experiment 2) of male lambs fed high urea diet. Treatments in two experiments were (1: basal diet + whole barley grains, 2: basal diet + ground barley grains with a 5 mm screen, 3: basal diet + ground barley grains with a 3...

introduction: the mechanisms of hepatic encephalopathy are not fully understood. moreover, there is no comprehensive data concerning the effects of nitric oxide (no) system on anxiolytic-like behaviors induced by bile duct ligation (bdl). methods: male mice weighing 25-30 g were used and anxiety-like behaviors were tested using hole-board task. results: the data indicated that cholestasis incre...

Methods 123 patients with no obstructive epicardial coronary artery disease, defined by coronary computed tomographic angiogram demonstrating < 30% stenosis, underwent regadenoson CMR 1st-pass perfusion imaging, using 0.05 mmol/kg gadolinium (Gd) followed by rest perfusion imaging (also 0.05 mmol/kg Gd) performed 20 minutes later. The subjects were categorized into 4 groups: normal BMI (between...

introduction: butylated hydroxytoluene (bht 2, 6-di-tert-butyl-p-cresol) is one of the extensively used antioxidants in the food industry. it is used in low-fat foods, fish products, packaging materials, paraffin, and mineral oils. bht is also widely used in combination with other antioxidants such as bha, propyl gallate, and citric acid for the stabilization of oils and high-fat foods. on the ...

The objectives of this experiment were to determine the effects of forage type on nutrient digestibility, purine derivative excretion, nitrogen utilization, and milk production in dairy cattle consuming rations containing high levels of wet distillers grains with solubles (WDGS). Primiparous (n=8) and multiparous (n=20) Holstein cows were used in a replicated 4 x 4 Latin square. Animals were fe...
