Using wheat as an energy source for beef cattle

07.11.2014

Wheat, along with corn and barley, is one of the three major feed grains used in North America. Most of the feed-class wheat is fed to poultry and swine. Beef producers are reluctant to use large quantities of wheat in diets of feedlot cattle because wheat ferments considerably more rapidly in the rumen than corn or barley and increases the risk of ruminal acidosis, which can compromise the health, wellbeing, and productivity of cattle.

In a study published in the November 2014 issue of the Journal of Animal Science (“Impact of hard vs. soft wheat and monensin level on rumen acidosis in feedlot heifers”) researchers in Canada conducted a metabolism trial using fistulated beef heifers to determine whether different types of wheat grain could be fed as an alternative energy source.


Dr. WenZhu Yang, a research scientist at the Agriculture and Agri-Food Canada—Lethbridge Research Centre, and colleagues determined whether soft wheat versus hard wheat might ferment at different rates and, therefore, have different values for feeding beef cattle. They also evaluated the effect of feeding more monensin (an ionophore used to improve feed efficiency and prevent or control coccidiosis) than the current practice, Yang indicated.

“The evaluation of these dietary factors was investigated by measuring ruminal pH and rumen fermentation, microbial protein synthesis in the rumen, and the site and extent of nutrient digestion by finishing beef heifers,” Yang said.

The researchers found that wheat can be fed at more than 50 percent of dietary dry matter without adversely impacting the feeding value of the wheat grain, Yang said. Beef producers need to pay attention to grain processing to ensure that ruminal starch digestion is not too fast, Yang said, which could result in subclinical ruminal acidosis or adversely impact animal health and growth performance.

The researchers also found that increasing monensin supplementation decreased feed consumption and increased propionate in the ruminal fermentation pattern, Yang said. Greater monensin feeding suggests a potential for improving feed efficiency.

“However, other factors such as proper feed adaptation, bunk management, and increasing the level of silage in the diet may also be effective management strategies,” Yang said.

Yang said he and his colleagues plan to further their research by determining the optimum processing of wheat grain. They are also developing near-infrared spectroscopy calibrations that will take composition and digestion rate into account.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
