sixty eight holstein cows, 38 primiparous and 30 multiparous, were employed in a randomized complete block design to evaluate the effects of 2 diets of varied rumine fermentable carbohydrate sources (corn grain (cg) and wheat grain (wg)) on blood metabolites and hormones during periparturint period. primiparous and multiparous cows were blocked by parity. the cows were fed diets as total mixed ...

Perchlorate (ClO4 (-)), an oxidizing agent, is a ubiquitous environmental pollutant. Several studies have investigated its thyroid hormone disrupting properties. Its associations with other biological measures are largely unknown. This study, combining 2005-2008 National Health and Nutrition Examination Surveys, investigated associations between urinary perchlorate and biomarkers of iron homeos...

effect of different irrigation regimes and nitrogen fertilizer on percentage of grain fatty acids, yield, water and nitrogen use efficiency of pumpkin was studies as split plot based on complete randomized block design with three replications in growing season of 2013. irrigation treatments (320, 420, 600 and 900 mm ha-1) were se as main plots and nitrogen fertilizer (0, 130, 260, 390 and 520 k...

In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 kg N.ha-1 each) for Yazd location )0, 43.5, ...

introduction ensiling is less dependent to weather condition and farmers are trying to ensile forages for preserving them for livestock feeding. ensiling legumes because of their buffering capacity and high moisture content are difficult. also, ensiling alfalfa will lose up to %85 of its nitrogen content as non-protein nitrogen. adding some additives like carbohydrate sources will improve alfal...

a trial study was set to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on accumulation and translocation of wheat stem reserves, at the agricultural faculty of shahid chamran university of ahvaz during 2011-2012. the experimental design was split plot at randomized completed block design arrangement. the main plot were differen...

High blood urea nitrogen (BUN) concentration is linked to low fertility in cows and ewes; however, this relationship has not been reported mares. The study characterized the between BUN follicular fluid (FUN) during follicle growth (Experiment 1) impact of from embryo donors on pregnancy outcome recipient mares 2). In experiment one, samples were collected diestrus with growing follicles estrus...
