Grass species represent a major source of food, feed, and fiber crops and potential feedstocks for biofuel production. Most of the biomass is contributed by cell walls that are distinct in composition from all other flowering plants. Identifying cell wall-related genes and their functions underpins a fundamental understanding of growth and development in these species. Toward this goal, we are ...
Although the c. 10,000 species in the Poaceae places it as the fifth largest flowering plant family, a number of biological features raise it to a unique position. The family has contributed crop species that provide about 80% of the annual global food (FAOSTAT 1999). In fact, four of the top crops that feed the world are cereal crops: wheat, rice, corn, and barley. This economic significance i...
Low live weight gain of cattle in the wet season of tropical areas was identified as a major limitation to achieving annual growth rates from tropical pasture systems sufficient to meet new market specifications of young animals of high carcass weight. Both protein and energy are limiting nutrients for growth. Net transfer of feed protein to the intestines is often not complete, and losses occu...
Citation: Klotz JL and Smith DL (2015) Recent investigations of ergot alkaloids incorporated into plant and/or animal systems. Front. Chem. 3:23. Ergot alkaloids have been associated with endophyte-infected grasses (e.g., the Epichloë, Bacon et al., 1977 and Balansia, Porter et al., 1979 spp.) with examples including tall fescue and fescue toxico-sis in the United States (Yates et al., 1985) as...
Studies across 5 yr involving 938 British-breed crossbred cattle (372 heifers, 566 steers) were used to evaluate the effects of grazing alternate summer and fall forages on slaughter breakeven cost of various beef production systems. Grazed summer forage combinations included 1) continuous brome, 2)brome and warm-season grasses, 3) brome and alfalfa or sudangrass, 4) brome and a monoculture of ...
