Experiences with grazing the new annual pasture legume Biserrula pelecinus L . in southern Australia production benefits and risk of photosensitisation
Biserrula pelecinus (L.) is a species of annual legume located in the Galegeae tribe of the Leguminosae family.It is endemic to the Mediterranean basin and was first commercialised as a pasture plant in Australia in 1997.It is often used in a ley farming system where it self‐regenerates from persistent seed banks after one or more cereal crops.Its key features are high seed production, high hard seed content, small seeds, deep root system and acid soil tolerance (Loi et al.2005).Biserrula has a high protein content, particularly as a dry feed and is tolerant of heavy grazing by sheep and cattle.Sheep will preferentially avoid grazing biserrula in some circumstances ( Revell and Thomas 2004 ) and it has been associated with cases of photosensitivity when it dominates the sward.We tested the hypothesis that the aversion response is a function of elevated rumen ammonia resulting from the high protein content of biserrula herbage.
