Six yearling Hereford X Angus steers (avg 272 kg), each with ruminal, duodenal and ileal cannulas were used in a 6 X 6 Latin-square metabolism trial to evaluate the impact of NaHCO3 and trona (a ground, nonrefined ore with chemical composition NaHCO3-Na2CO3-2H2O) on site and extent of digestion of nutrients in the digestive tract. The diets were 50:50 or 90:10 (cracked corn-based concentrate:co...

BACKGROUND Feeding polyphenol-rich plant products has been shown to increase the gain:feed ratio in growing pigs. The reason for this finding has not yet been elucidated. In order to find the reasons for an increase of the gain:feed ratio, this study investigated the effect of two polyphenol-rich dietary supplements, grape seed and grape marc meal extract (GSGME) or spent hops (SH), on gut morp...

A study was performed to: 1) compare total tract digestibility of nutrients for three annual summer forages: Mulato II (hybrid Brachiaria); “Tifleaf 3” Pearl Millet (Pennisetum glaucum); and “Hay Day” Sorghum sudan (Sorghum bicolor) and 2) determine the efficacy of two digestibility markers: titanium dioxide (TiO2) and chromic oxide (Cr2O3) used with a fecal sample collection protocol of either...

in order to investigate the effect of partial replacement of barley starch with beet pulp soluble fiber with or without roasted canola seed on apparent nutrient digestibility, dry matter intake, daily weight gain, feed conversion ratio and rumenal ph 24 arabian male lambs were used for 84 days in a completely randomized design with a 2×2 factorial arrangement. treatments had no significant effe...

Many equine nutrient requirements are based on certain assumptions about how well horses digest and absorb nutrients. Unfortunately, a great many questions remain unanswered about nutrient digestibility in horses. How well do horses utilize different sources of nutrients? What nutrients interact with one another to affect digestibility? Over the past five years, Kentucky Equine Research has con...

A practical approach to determine apparent faecal digestibility using privately owned dogs may be a useful tool in evaluating differences in nutrient digestibility between dogs with various life stages. The aim was to develop a simple method that would suit such studies using the whitening agent titanium oxide (TiO2) as an indigestible marker. Forty privately owned, healthy male and female dogs...
