Two finishing trials and a metabolism trial were conducted to evaluate the effect of forage source and particle size in dry-rolled corn finishing diets. In Exp. 1, 224 crossbred yearling steers (BW = 342+/-11 kg) were used in a randomized complete block design consisting of seven treatments. Treatments were an all-concentrate diet or diets containing equal NDF levels provided by alfalfa hay or ...

a three-year field experiment (2004-2007) was conducted on a silty clay loam soil at tajarak research station of hamedan to determine proper grain drill for wheat in hamedan dryland areas. in this study, three grain drills including: hamedani barzegar; sahalan kesht; and kesht gostar with wheat seed broadcasting and disking were used. the experiment was a randomized complete block design with f...

In this study, a fixed-site field experiment was conducted to study the influence of different combinations of tillage and straw incorporation management on carbon storage in different-sized soil aggregates and on crop yield after three years of rice-wheat rotation. Compared to conventional tillage, the percentages of >2 mm macroaggregates and water-stable macroaggregates in rice-wheat double-c...

The objective of this study was to evaluate properties of experimental particleboard panels manufactured from wheat straw that had been pretreated with acetic anhydride, soapy solution, hot water, or steam. Wheat straw particles were mixed with commercially manufactured wood particles at a ratio of 60%. Control straw particleboards with non-treated straw and wood particles were also produced. T...

13 The purpose of the study was to investigate the influence of torrefaction on the grindability of wheat straw. 14 Straw samples were torrefied at temperatures between 200 ̊C to 300 ̊C and with residence times between 0.5 to 15 3 hours. Spectroscopic information obtained from ATR-FTIR indicated that below 200 ̊C there was no obvious 16 structural change of the wheat straw. At 200-250 ̊C hemice...

The thermogravimetric characteristics of wheat straw EMAL (Enzymatic Acidolysis Lignin) were analyzed. The effect of the heating rates on the thermogravimetric characteristics of wheat straw and the wheat straw influence on pyrolysis were investigated. The influence of various heating rates on wheat straw was significant, the pyrolysis rate of wheat straw EMAL increased at temperatures between ...

introduction feed shortage is the most important characteristic of iranian animal industry. increased costs of livestock production have caused the iranian producers to reduce feed costs mainly by inclusion low quality crop residues into ruminants diets. it is estimated that around 20 million tons wheat straw produced in iran every year. both the digestibility and crude protein content of wheat...

Perennial herbaceous crops can become the main basis for renewable energy production in agricultural ecosystems in future. To determine the plant species that are the most suitable for biomass production, their biological peculiarities and productivity, biochemical composition and thermophysical properties, social and ecological impact must be investigated thoroughly. The local varieties of per...

Organic matter plays a key role in availability and transformation of soil Zn (zinc), which greatly controls Zn concentrations in cereal grains and human Zn nutrition level. Accordingly, soils homogenized with the wheat straw (0, 12 g straw kg-1) and Zn fertilizer (0, 7 mg Zn kg-1) were buried and incubated in the field over 210 days to explore the response of soil Zn availability and the agein...

The potential of urea molasses liquid diet (UMLD) with two levels of roughage as survival feed (Phase-I) and its impact on the performance during revival period (Phase-II) was studied on eight growing buffalo calves (209 kg mean body weight; 1 year age) divided into two equal groups in a completely randomised design. In the ®rst phase, the calves of both the groups were offered 3 kg UMLD (molas...
