RATIONALE The use of stable isotopes for dietary estimates of wildlife assumes that there are consistent differences in isotopic ratios among diet items, and that the differences in these ratios between the diet item and the animal tissues (i.e., fractionation) are predictable. However, variation in isotopic ratios and fractionation of δ13 C and δ15 N values among locations, seasons, and forage...

Silvopasture is the intentional integration of trees, forages, and livestock. Benefits this agroforestry practice include shade for livestock, nutritious forage, reduced wind speed in pastures, as well ecosystem services tree products. The literature indicate that some livestock producers are interested silvopasture, but little known about their establishment preferences if they vary by demogra...

In recent years, several secondary plant metabolites have been identified that possess antimethanogenic properties. Tannin-rich forages the potential to reduce methane emissions in ruminants while also increasing their nutrient use efficiency and promoting overall animal health. However, results highly inconclusive date, with effects on both performance nutrition being variable even within a sp...
