“…Abortion in females surviving nitrate–nitrite poisoning incidents is common in cattle 6 and the cause is believed to be fetal hypoxia as a consequence of maternal methaemoglobinaemia 10 . The timing of the abortion in this case suggests that one or more of the oaten hay bales fed before 12 August (the day of the deaths) caused non‐lethal nitrate–nitrite poisoning in the alpaca flock.…”

Nitrate-nitrite poisoning killed four adult alpacas and induced the abortion of a full-term fetus after access to oaten hay (Avena sativa) containing 3.2% KNO(3) equivalent in dry matter. Necropsy findings were cyanosis, dark-coloured blood, and pulmonary congestion and oedema. Aqueous humour from two adults contained 25 mg NO(3)/L and that from the fetus contained 10 mg NO(3)/L. Cyanide poisoning possibly killed two adult wether alpacas that ate a garden-cultivated variety of Osteospermum ecklonis (South African daisy, bietou) with a cyanide potential of 6800 mg HCN/kg dry matter.
