Beef steers (n = 11,877) from 7 studies were fed zilpaterol hydrochloride (ZH) for 0 or 20 to 40 d before slaughter to determine the effects of ZH on subprimal weight and yield. Carcasses were selected based on mean HCW of treatment groups for fabrication into boneless, closely trimmed, or denuded subprimals, lean, fat, and bone. Data from the 7 trials were pooled for statistical analysis. Feed...
background and objectives: evaluation of the grain yield and yield components and also morphological traits can help to identify strategies for selection of resistant cultivars and increased crop yield production under heat stress condition. to this end, in experiment to evaluate of grain yield and yield components on 42 rice lines tolerant to heat stress from international rice research instit...
The present study was conducted to evaluate the influence of gibberellic acid (25, 50, 100, and 200 ppm) applied on saffron corms previously harvested during different periods (March, June, before planting) growth quantitative qualitative yield (Crocus sativus L.). carried out in field 2016-2017 2017-2018 seasons experimental station Faculty Sciences Oujda (Morocco). measured parameters corresp...
in the country, reducing water resources and increasing water losses in the various methods of surface irrigation, has increased attention, super drip irrigation method, especially drip tape irrigation. one of the techniques are used in cultivation of early sweet corn, the use of plastic mulch. using this technique, the reserve temperature conditions for plant growth and early maturity, resulti...
This study was carried out to compare agro-morphological traits and nutritive value of 25 tall fescue (Festuca arundinacea) ecotypes grown in Tehran, Iran. The experiments were carried out in a split plot design during 2016-2018 growing seasons. The results showed that there was a significant genetic variation in existing germplasm. The highest heritability was related to dry forage yi...
A Comparative Report on the Percentage Yield of Volatile Oil from Citrus Fruits by Hydrodistillation
In order to investigate yield, yield components and quality traits of P. ovata and P. psyllium under water stress and plant density, two experiments were conducted at the Agriculture Research Field, University of Tehran, Karaj, in April 2005 and 2006. Two Factorial experiments based on randomized complete block design with three replications were used. The treatments were three levels of water ...
Previous studies have demonstrated that the p.Lys232Ala substitution in the acylCoA: diacylglycerol acyltransferase (DGAT1) gene and the p.Phe279Tyr mutation in the growth hormone receptor (GHR) gene are the causative quantitative trait loci underlying milk yield and composition on BTA14 and BTA20 respectively. To examine their applications in the genetic improvement of Chinese dairy cattle pro...
