A study was carried out to investigate the sodium requirements of broiler chicks in the first week post-hatching using diets with two dietary electrolyte balances (DEB). During the first week, birds were given feeds with four levels of total sodium (0.12, 0.24, 0.36, and 0.48%) and two DEB (Na+ + K+ − Cl− = 160 or 240 mEq/kg). Feeds given thereafter to 42 d had common formulation. Both sodium a...

The effects of chronic dietary acid loads on shifts in bone mineral reserves and physiological concentrations of cations and anions in extracellular fluids were assessed in growing swine. Four trials were conducted with a total of 38 (8.16 +/- 0.30 kg, mean +/- SEM) Large White x Landrace x Duroc pigs randomly assigned to one of three dietary treatments. Semipurified diets, fed for 13 to 17 d, ...

Dietary electrolyte balance is calculated as the sum of Na and K minus Cl and is expressed in mEq/kg of diet. The manipulation of dietary electrolyte balance (dEB) to enhance lactation and reproductive performance in dairy cattle and laying hens is not a new concept. However, the effects of dEB on reproduction and lactation in sows have not been elucidated. Thus, our objective for the experimen...

Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at differen...

Twenty-one Lori–Bakhtiary sheep were randomly allocated into 3 groups to compare the effects of oral selenium nano particles (Se NPs) and sodium selenite (Na-Se) supplementation on serum selenium, copper, zinc, molybdenum, manganese and cobalt concentration. Groups 1 and 2 orally received Se NPs and Na-Se (1 mg/kg) for 10 consecutive days, respectively ...

DEB dehydrogenation reaction was conducted to produce divinylbenzene (DVB) and ethylvinylbenzene (EVB). The effects of temperature, catalyst weight and time factor on the performance of the dehydrogenation reactor were investigated experimentally. Temperature was varied from 550º C up to 600 º C. Temperature affect the conversion of DEB to DVB significantly. The mole fraction of DEB in the outl...

statins have antioxidant and anti-inflammatory effects that are not directly related to their cholesterol-lowering activity. this study aimed to investigate the effect of simvastatin on the extent of tissue damage in cisplatin-induced nephrotoxicity. simvastatin was orally given to rats in different doses (1, 2 and 4 mg/kg), 1 h prior to cisplatin injection (5 mg/kg, i.p.). all animals were dec...
