(Press-News.org) URBANA, Ill. - Distillers dried grains with solubles, or DDGS, are increasingly common in swine diets in the United States. In recent years, different types of DDGS have come on the market.
"Ethanol plants use different procedures to produce DDGS, which results in different end products," said Hans H. Stein, a professor of animal sciences at University of Illinois.
"To produce conventional DDGS, the corn is cooked to gelatinize starch prior to fermentation. However, uncooked DDGS can also be used if specific enzymes are used to pre-digest the starch prior to fermentation. Some ethanol plants also use a different fractionation technology to produce DDGS with more protein than conventional DDGS."
Stein's team tested diets containing 30 percent conventional DDGS (DDGS-CV), high-protein distillers dried grains (HP-DDG), or uncooked DDGS (DDGS-BPX), and compared them with a corn-soybean meal basal diet. They conducted one experiment using growing pigs and another experiment using finishing pigs to determine if the stage of growth of pigs affected their utilization of the different ingredients.
Results indicated that pigs fed DDGS-CV, HP-DDG, or DDGS-BPX had no differences in average daily gain, average daily feed intake, and gain to feed ratio compared with pigs fed the basal diet. This was true for both growing and finishing pigs.
With a few exceptions, there was no difference in retention of energy, protein, or lipids between pigs fed the test ingredients. Growing pigs fed the basal diet retained more protein than pigs fed DDGS-CV or HP-DDG. Finishing pigs fed DDGS-BPX had greater lipid gain than pigs fed DDGS-CV. Net energy in DDGS-CV was greater than in HP-DDG or DDGS-BPX if fed to finishing pigs, but that was not the case if fed to growing pigs.
"Results from this study indicate that whereas there are some differences in retention of energy and nutrients among the different sources of DDGS, these differences are not of such a magnitude that they affect growth performance," said Stein. "Conventional, high-protein, or uncooked DDGS can be included at up to 30 percent in growing and finishing pig diets without a negative effect on performance."
The study, "Effects of co-products from the corn-ethanol industry on body composition, retention of protein, lipids and energy, and on the net energy of diets fed to growing or finishing pigs," was published in a recent edition of the Journal of the Science of Food and Agriculture. It was co-authored by Nestor Gutierrez, Dong Yong Kil, Yanhong Liu, and James Pettigrew.

WINSTON-SALEM, N.C. - March 20, 2015 - Medicine obviously can't do much good if it sits on a pharmacy shelf. Yet more than one-quarter of the acne patients surveyed by Wake Forest Baptist Medical Center researchers didn't get medications prescribed by their dermatologists.
Among the 143 acne patients who participated in the study, 27 percent failed to obtain all of their medications, including both prescription drugs and over-the-counter products. Those who were prescribed two medications had the highest rate of primary non-adherence - not getting a medication or not using ...
Philadelphia, PA, March 20, 2015 - A new study provides the first evidence that the mediator complex subunit 15 (MED15) may play a crucial role in the pathophysiology of head and neck squamous cell carcinoma (HNSCC). MED15 overexpression was found to be associated with higher mortality rates in HNSCC patients with cancer recurrence, particularly in oral cavity/oropharyngeal tumors, according to the study published in The American Journal of Pathology. MED15 overexpression was also associated with heavy alcohol consumption, which is an HNSCC risk factor.
HNSCC is the sixth ...
Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light. The new approach doubles the 1 bit per photon that is possible with current systems that rely on light polarization and could help increase the efficiency of quantum cryptography systems.
Quantum cryptography promises more secure communications. ...
FORT LAUDERDALE-DAVIE, Fla. - Tigers - they are some of nature's most beautiful, deadly and endangered species. In fact, living tigers are severely endangered in fragmented geographic areas across Asia - some reports show their numbers as low as 3,000 wild individuals. While there are efforts to help protect these magnificent creatures, more was needed in terms of research into the genetics of tigers.
Nova Southeastern University researcher Stephen O'Brien was part of a team of research scientists from China, the United Kingdom, Israel, Russia and Qatar that looked at ...
A new study in Marketing Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS), finds that most firms do not use the skimming or penetration strategies that deliberately overprice or underprice new products.
Skimming or Penetration? Strategic Dynamic Pricing for New Products appears in the Articles in Advance Section of Marketing Science. The research was conducted by Martin Spann, Ludwig-Maximilians-University Munich; Marc Fischer, University of Cologne and University of Technology, Sydney; and Gerard J. Tellis, Marshall School ...
Measuring the concentration of leukemia cells in patient bone marrow during the first 46 days of chemotherapy should help boost survival of young leukemia patients by better matching patients with the right intensity of chemotherapy. St. Jude Children's Research Hospital investigators led the research, which appears in the March 20 edition of the journal Lancet Oncology.
The findings stem from a study of 498 children and adolescents with acute lymphoblastic leukemia (ALL) enrolled in a St. Jude-led protocol between 2000 and 2007. The clinical trial was the first to use ...
MANHATTAN, Kansas -- Kansas State University scientists have released findings of a complex, two-year study of the genomic diversity of wheat that creates an important foundation for future improvements in wheat around the world.
Their work has produced the first haplotype map of wheat that provides detailed description of genetic differences in a worldwide sample of wheat lines. In genetics, a haplotype map is a powerful tool for transferring sequence-level variation to multiple gene mapping projects.
"All of these new, genomic-based strategies of breeding promise ...
EAST LANSING, Mich. - Recycling plastic works; additives to biodegrade plastic do not.
A new study from Michigan State University shows that several additives that claim to break down polyethylene (i.e., plastic bags) and polyethylene terephthalate (i.e., soda bottles) simply don't work in common disposal situations such as landfills or composting.
"Making improper or unsubstantiated claims can produce consumer backlash, fill the environment with unwanted polymer debris and expose companies to legal penalties," said Susan Selke, co-author of the study and MSU packaging ...

A plant scientist from The Australian National University (ANU) has called for the United Nations to guarantee free and open access to plant DNA sequences to enable scientists to continue work to sustainably intensify world food production.
Dr Norman Warthmann, a plant geneticist at the ANU Research School of Biology, has lodged a submission with the UN, which is currently considering issues to include in its 2015 Global Sustainable Development Report.
Food security depends on an acceleration in plant breeding, which could be threatened by private companies restricting ...
