NIRS workshops at the Alberta Crop Industry Development Fund Ltd. in Lacombe and Lethbridge, Alberta Canada, delivered a strong message– “It has never cost more to feed a pig (or anything else), and what are the key limitations to using NIR?”
The singular answer from the audience was “training and education.” Side discussions regarding the use of in-line NIR concluded that In-line NIR technology is effective in reducing process variation and reducing sampling error which is generally much larger than instrument error. This suggests there is still more opportunity for improving grain utilization and minimizing labor. New in-line applications using the multiplexing Bruker FT-NIR were discussed at the Bruker booth.
Bruker is holding a NIR Spectroscopy technical session at the Liquid Feed Symposium, hosted by the American Feed Industry Association (booth #14), September 12-14 in Denver.
The technical session includes a variety of topics, which are sure to be of interest to a broad spectrum of people involved in the manufacture of liquid feeds, and those employed in supporting industries.
At the 2012 Poultry Science Association meeting in Athens, Georgia, and the JAM joint annual meeting in Phoenix conference rooms were at capacity—reflecting high interest for the latest feed research. Improving biological availability and use of feed nutrients was the focus of both events. Bruker Optics instruments were cited in multiple presentations and the new Tango for feed mills, and the Matrix F for inline measurement and real-time control of feed production were exhibited at both meetings.
Vast progress is being made in making NIR technology practical and accessible for feed producers. Significant commercial developments are now on the horizon. Since the mid-70’s computer and optical system technologies have steadily evolved. We are now at the point of implementing real-time solutions and commercial implementation may be in the not-to-distant future to reach a tipping point. Prolific adoption of Bruker Fourier Transform -NIR technology in the pharmaceutical and chemical industries has supported this development.
As our pets are living longer, Chondroitin sulfate (CS) as a supplement for degenerative joint disease, or osteoarthritis is a particularly hot area, available as infused chewable tablets, treats, or as a functional ingredient in pet foods formulated for senior pets.
In animals and humans, CS is naturally produced by the body as a component of cartilage and joints. With age, the amount of CS in the body decreases, and supplementation reduces inflammation, minimizes cartilage damage and provides joint lubrication. As a raw material, CS is a natural polymer typically sourced as a finely ground white powder that is produced from bovine, porcea trachea, shark or chicken cartilage.
Timing is everything! Under-mixing can lead to uneven distribution of ingredients throughout the batch, resulting in a final product that is over or under fortified. Over-mixing wastes energy, time and reduces throughput and can result in stratification or un-mixing.
Although target mix times are usually well-known for specific formulations, many factors influence the optimum time needed for an individual batch including wear of equipment, lot-to-lot variation of raw materials, or environmental conditions.
You are what you eat – and this is particularly true if you are a hog. Up to 75 percent of the fat in swine feed rations finds its way directly to a hog’s body fat. Hog producers are under considerable pressure to reduce operating costs to maintain profitability. One way to lower feed costs is to increase the incorporation of distillers grains – DDGs – in the hog’s feed rations.
Reducing feed costs in this manner is not without consequences. The fat in DDGs is significantly different than native corn oil. The free fatty acid content is considerably higher, and the level of unsaturated fats is elevated. This leads to elevated levels of unsaturated fats in the hog’s carcass fat.
See Bruker at the upcoming Poultry Science Association’s Annual Meeting in Athens, Georgia July 9-12, 2012. Hundreds are expected to attend this year’s meeting which promises to stimulate discovery, application, and dissemination of knowledge.

Premier Pet Nutrition (PPN), part of the ABF plc group, invited 2012 INTERZOO attendees to test their pet food “live” using Bruker’s Tango in their booth, in Nurnberg, Germany.
The Tango produced simultaneous results for fat, protein, moisture, fiber, ash and cook values in seconds. After the tests were completed, the Tango printed a Certificate of Analysis right at the booth.
A comparison study of various chemometric approaches, including LS-SVM, for large near-infrared spectroscopic data of feed and feed products found an RMS improvement of 10% to 24%, according to a white paper published in 2011.
This substantial improvement is quite meaningful and will soon be commercially implemented on Bruker’s FT-NIR platforms providing the very best accuracy and stability. Within the food and agriculture industries there are fantastic challenges and rich opportunities for those inclined to apply their professional skills in developing models and computational solutions.
