A meta-analysis was performed to determine the influence of cereal grain type and corn grain harvesting and processing methods, dietary starch, rumen-digestible starch, and forage NDF concentrations on intake, digestion, and lactation performance by dairy cows using a data set comprising 414 treatment means from 102 peer-reviewed journal reports from 2000 to 2011. Categories for corn processing...

Energy outputs from ethanol produced using corn, switchgrass, and wood biomass were each less than the respective fossil energy inputs. The same was true for producing biodiesel using soybeans and sunflower, however, the energy cost for producing soybean biodiesel was only slightly negative compared with ethanol production. Findings in terms of energy outputs compared with the energy inputs wer...

The Response of Morphological and Physiological Traits Grain Yield Corn to Planting Method Sugarcane Residue Compost

To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

Microbial protein synthesis in the rumen would be optimized when dietary carbohydrates and proteins have synchronized rates and extent of degradation. The aim of this study was to evaluate the effect of varying ruminal degradation rate of energy and nitrogen sources on intake, nitrogen balance, microbial protein yield, and kinetics of nutrients in the rumen of growing kids. Eight Boer goats (38...

Improvement of USDA Select grade beef is essential for consumer acceptance of leaner beef. Seventy-two large- and medium-framed steer calves of mixed breeding were used in two experiments to evaluate feedlot performance, carcass composition, and beef palatability. Interactions of dietary energy level (corn concentrate or corn silage), breed type (Angus or Simmental), carcass electrical stimulat...

Corn silage is a major forage crop in Idaho, supporting its dairy industry. Corn silage produces more digestible energy per acre than other forages. Nutritionally, corn silage is palatable when ensiled properly, and high in energy because it typically contains 50% corn grain. Digestibility of starch declines as the kernel matures. Effective roller processing of corn silage ensures that most of ...

As a major part of farming sustainability, the issues of grain production and its quality improvement have been important in many countries. This paper aims to address these issues in China. Based on the data from the main production provinces and by applying the stochastic frontier analysis methodology, we find that the improvement of transportation and the use of agricultural machinery have b...
