This study was designed to determine the effect of physical form and urea treatment of rice straw on rumen fermentation, microbial protein synthesis and nutrient digestibility. Four rumen-fistulated d...
The aim of this study was to determine the effect of different physical forms and urea treatment of rice straw on feed intake, rumen fermentation, and milk production. Four, multiparous Holstein cross...
Two experiments were conducted to determine an optimum Lys:calorie ratio (g of total dietary Lys/Mcal of DE) for growing barrows and gilts in cool and hot seasons in a commercial environment. In Exp. ...
Four, ruminally fistulated crossbred (Brahman×native) beef cattle with initial body weight of 420±15 kg were randomly assigned according to a 4×4 Latin square design. The dietary treatments were mulbe...
To evaluate the effects of replacing concentrate with urea molasses treated fermented wheat straw (FWS) ensiled with cattle manure (CM) on ruminal characteristics, in situ digestion kinetics and nitro...
Dissolved nitrogen (N) as urea ([NH2 ]2CO), nitrate (NO{ 3 ), and ammonium (NHz 4 ) was added to naturally phosphorus (P)-rich lake water (up to 175 mg P L21 ) to test the hypotheses that pollu...
Urea is the most abundant nitrogen (N) fertilizer used on agricultural soils, yet its effects on adjacent aquatic ecosystems are largely unknown. Here 21-d, 3000-liter mesocosm experiments were conduc...
Some pyridazine derivatives carrying urea, thiourea, and sulfonamide groups were synthesized and evaluated for their antimicrobial activity against gram-positive and gram-negative bacteria, and fungi ...
A quantitative method for the determination of urea in serum was studied. An ion chromatograph (IC) with a conductivity detector was used in this method, where the chromatograph was modified by placin...
Nickel limitation and zinc toxicity in a urea-grown diatom     Nickel limitation  zinc toxicity  urea-grown diatom       font style='font-size:12px;'> 2014/4/21
When growing on urea as a nitrogen source, diatoms must accumulate nickel (Ni), a cofactor in the urease enzyme, which hydrolyzes urea. The uptake of Ni at low ambient concentrations is particularly c...
The objective of this study was to determine the optimum ratio of methionine to methionine plus cystine for growing pigs. A nitrogen balance trial was conducted using a total of 21 barrows (Large Whit...
