Latent Anti-nutrients and Unintentional Breeding Consequences in Australian Sorghum bicolor Varieties

Modern feed quality sorghum grain has been bred to reduce anti-nutrients, most conspicuously condensed tannins, but its inclusion in the diets of monogastric animals can still result variable performance that is only partially understood. Sorghum contains several negative intrinsic factors, including non-tannin phenolics and polyphenols, phytate, kafirin protein, which may be responsible for these muted performances. To better understand phenolic polyphenolic metabolites have effects on nutritional parameters, chemical composition polyphenol extracts from three commercial varieties (MR-Buster, Cracka, Liberty) was determined through use an under-studied, alternative analytical approach involving Fourier-transform infrared (FT-IR) spectroscopy direct ionization mass spectrometry. Supervised analyses interrogation data contributing variation resulted identification a variety metabolites, established lignin-like complex sugars, as well high levels fatty acids could contribute underperformance monogastrics. FT-IR spectrometry both discriminate among different indicating FT-IR, rather than more sophisticated chromatographic spectrometric methods, incorporated into control applications.
