Avoid planting fescue in your pasture. Although some breeders claim to have their herds on pastures of fescue with no problems, others report fescue is the cause of reproductive problems such as abortions and premature births. Fescue is also said to elevate the body temperature in llamas/alpacas. The problem stems from a fungus on the fescue called endophyte. Further info on Fescue Toxicity.
