In this assay, edible cattle tissues from local markets of Ardabil, a Province of Iran, were examined for residues of tetracycline antibiotics (tetracycline, oxytetracycline and chlortetracycline). In total, 110 samples of triceps, gluteal muscle, diaphragm, kidney and liver were randomly obtained from the local markets of the city of Ardabil. Solid-phase extraction (SPE) and high-performance l...

Assumptions about the importance of mothers’ time for children’s healthy development permeate policy debates over child care, maternal employment, and family leave. Studies consistently show that mothers’ time in particular activities with children relate positively to indicators of child well-being, but results are more mixed regarding associations between child outcomes and the sheer amount o...

ABSTRACT- Crop residue is applied to amend soil properties and increase crop yield. In this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. The experiment was conducted at the Experimental Farm of College of Agriculture, Shiraz University, located at Badjgah, Shiraz, Iran in 2007-2008...

Five studies were conducted to determine nutrient digestibility and performance of lambs and steers fed thermochemically treated crop residues and distillers dried grains with solubles (DDGS) as a corn replacement pellet (CRP; 75% residue:25% DDGS, DM basis). Fifteen Hampshire, Suffolk, or Dorset wethers (BW 33.3 +/- 5.0 kg) were utilized to evaluate nutrient digestibility of the unprocessed na...

Phosphorus (P) unavailability and lack of organic matter in calcareous soils semiarid climates are the major reasons for low crop productivity. This field experiment was conducted at Agronomy Research Farm The University Agriculture Peshawar, during summer 2015 to investigate impact plant residues (PR) (faba bean, garlic paper mulberry residues) phosphorous sources [(60 120kg ha-1) from single ...

Development and application of modem technology for upgrading straw in Europe during the 1970's has stimulated intense interest in developing countries. Since 1980, twenty four international workshops have been held in Africa and Asia to consider research and development on crop residues as feed, with emphasis on improving their intake and digestibility in ruminants by treatment with ammonia ge...

This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States for bioenergy production. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included ...

THE EXISTING US Renewable Fuel Standard (RFS) makes commercial-scale cellulosic ethanol a priority, calling for 16 billion gallons of cellulosic biofuel production by 2022, sourced from grasses, trees, agricultural residues, and municipal waste. The US Department of Energy “US Billion-Ton Update” study (Downing et al. 2011) suggests that to meet the mandates in the RFS, approximately 66 million...
