  • "Effects of polyurethane coated urea supplement on in vitro ruminal fermentation, amomonia release dynamics and lactating performance of holstein dairy cows fed a steam-flaked con-based diet"

Xin HS, Schaefer DM, Liu QP, et al., Asian-Australasian Journal of Animal Sciences 23 (4): 491-500 Apr 2010. Three experiments were conducted to investigate the effects of polyurethane coated urea on in vitro ruminal fermentation, ammonia release dynamics and lactating performance of Holstein dairy cows fed a steam-flaked corn-based diet.

  • "Finishing steers with diets based on corn, high-tannin sorghum, or a mix of both: Feedlot performance, carcass characteristics, and beef sensory attributes"

Larrain RE, Schaefer DM, Arp SC, et al, Journal of Animal Science 87 (6): 2089-2095  Jun 2009. The objective of this work was to compare feedlot performance, carcass characteristics, and beef sensory attributes from steers finished with diets based on corn, high-tannin sorghum (HTS), and a mix of both grains. Keywords: C 14 Labeled Condensed Tannins; Bird Resistant; Growth Performance; Digestibility; Alkylphenols.

  • "Use of digital images to estimate CIE color coordinates of beef"

Larrain RE, Schaefer DM, Reed JD, et al., Food Research International 41 (4): 380-385 2008. The objective of this study was to evaluate the use of digital images (DI) to estimate CIE L*a*b*, hue angle and chroma of beef, as compared to a colorimeter (CM). Loin samples from 21 steers finished with high grain diets were displayed under retail-simulated conditions. Color readings were obtained from 63 cores covering the full spectrum of discoloration in beef.

  • "Growth performance and muscle oxidation in rats fed increasing amounts of high-tannin sorghum"

Larrain RE, Richards MP, Schaefer DM, et al., Journal of Animal Science 85 (12): 3276-3284 Dec 2007. The authors concluded that inclusion of 35% HTS in the diet increased intake and growth rate of young, fast-growing rats without changing the efficiency of gain. Feeding HTS reduced markers of protein oxidation in rat muscle after 6 d of refrigerated storage. If similar results are observed in animals such as swine or cattle, the use of HTS as animal feed should be reassessed.
