in order to investigate the effects of organic, chemical and biological fertilizers on crude protein and oil yields and fatty acids composition in black seed (nigella sativa l.), a field experiment was conducted at agricultural research station of ferdowsi university of mashhad, iran, in 2009-2010. the experiment was arranged by using a complete randomized block design based on factorial arrang...

the relationship between blood physiological attributes and carcass characteristics wasstudied in 40 randomly selected 8-month-old ram lambs of ghezel and mehraban (20 rams per breed)sheep. one day before slaughter, blood samples were obtained after a 24 hr fast. serum samples wereassayed for glucose, cholesterol, serum urea nitrogen (sun), total protein, albumin, triglycerides,creatinine, and ...

Hazelnut (Corylus avellna L.) is one of the important nut crops in world. The harvesting ofhazelnuts is done either by hand or by manual or mechanical raking of fallen nuts in Iran.Common hazel is widely cultivated for its nuts, including in commercial orchards in Europe,Turkey, and Iran. There are some genotypes of hazelnut in Iran that their growing areas arelimited to Gillan, Aredbil, Mazand...

The effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (Litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. There was no significant difference in final weight (m...

two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...

A surface plasmon resonance imaging-based Ni(2+)-iminodiacetic acid-coated gold chip system was developed to enable specific detection of a hexahistidine-tagged recombinant protein in crude extracts or in column chromatography fractions. This system is especially advantageous for high-throughput analysis of multiple proteins.

this study was carried out to determine the effects of gamma irradiation on dry matter (dm) and on crude protein (cp) degradation of rapeseed meal, using nylon bags and sds-page techniques. ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kgy were suspended in the rumen of four non-lactating holstein cows for up to 48 h. intestinal crude protein diges...

the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...
