Waste cooking oil (WCO) was used as a potential feedstock for biodiesel production. High levels of free fatty acids (9.85% w/w) in WCO made it an undesirable substrate for direct transesterification reaction. To solve this issue, a two-step process was implemented in this research. Firstly, esterification reaction was performed in presence of sulfuric acid as a common acid catalyst to reduce th...
The aim of this study was to examine the effect of Lactic acid bacteria based probiotic and its use schedule on Kurd male calves’ growth performance and white blood cell antimicrobial activity. The experimental period was 105 days after calves adapted to new environmental conditions. This study was carried out by 12 calves with an average body weight of 195 ± 10 kg and age of 240±10 days in a c...
In a completely randomized design, 600 commercial day old broiler chickens were used to study the possibility of replacing corn with barley. Each of 10 experimental diets in which corn was replaced with barley at levels of 0, 5, 10, 20 and 40 percent, with and without tallow, were given to 4 replicates of 15 chickens each. At 42, 49 and 56th days of age, one male and one female from each pen we...
the effect of in ovo injection of olive leaf extract as a growth promoter antibiotic was studied on hatchability, day old chick weight, growth rate, feed conversion ratio, mortality and carcass efficiency. three hundred and twenty eggs were divided into 4 groups, and injected on day 18. treatments consisted of: 1- control (no injection). 2- injection of 1 ml of distilled water in air sac (dw), ...
Polymorphonuclear cells of the peripheral blood in the chicken significantly increased their phagocytosis when cultured with sugar cane extract (SCE; 250-1,000 microg/ml) for 24 hr. Chickens orally administered SCE (500 mg/kg/day) for 3 or 6 consecutive days at 1 week of age showed significantly higher body weight and gain in body weight/day and a lower food conversion ratio within the growing ...
Introduction: Overweight and obesity are risk factors for developing many diseases such as hypertension. Furthermore, obesity indicators such as abdominal height, waist circumference and hip circumference can independently and sometimes more severely lead to blood pressure changes. The objective of this study was to evaluate the association between blood pressure changes and anthropometric in...
Background: The present study intended to determine and report patient effective dose on the basis of patients and exposure data. Materials and methods: A nationwide computed tomography (CT) survey was provided as a report of patient doses in 2015-2016. Scan details were collected for nearly 2,000 adults and children in four age groups subjected to CT examinations. From total 565 CT scanners in...
