Urinary blockage is more rare in male alpacas than goats and sheep, and even rarer in female alpacas than the males. An alpaca with pink eye should be isolated to avoid spreading the disease and kept in a cool, shady location removed from sunlight. Selenium is integral to numerous enzymes and proteins, including glutathione peroxidase, which prevents oxidative injury, as well as several enzymes involved in thyroid hormone homeostasis. An afflicted alpaca may not want to walk and might not be able to nurse any young. Measurements of serum and plasma selenium concentrations reflect the selenium associated with plasma proteins, which can fluctuate relatively rapidly along with exposure patterns. These are the symptoms of low selenium (just remember, they could also indicate other deficiencies! If an alpaca is suffering from an internal parasite, it is likely a strongyle, but there are other, more dangerous parasites such as lungworms, barber pole, and coccidia. The most typical case of urinary calculi in alpacas comes when a male alpaca is fed too much grain or generally has a calcium phosphorus imbalance in their diet, sometimes from an alfalfa-rich diet. It is caused by a nutritional deficiency of selenium, Vitamin E, or both. Foot rot refers to a bacterial infection of one or more feet of an alpaca, which can come on from chronically damp or muddy walking conditions for the alpaca as well as a zinc deficiency. The bacteria can activate and contaminate soil and grass in certain weather conditions, especially wet and cool weather followed by hot and dry weather. In the event of an abscess, it should be first diagnosed by a veterinarian, and typically it should be lanced and cleaned early on (any abscess on the face or neck should be treated by a veterinarian to minimize risk of major bleeding).

(Back to top), Parelaphostrongylus Tenuis(P. tenuis) is a parasitic worm whose natural host is the white-tailed deer. It is possible (though very rare) for CL to spread to humans, so its important to maintain good biosecurity when handling alpacas suspected of having CL. Absolute confirmation ofP. tenuiscan only be made during a post-mortem examination. Thiamine (Vitamin B1): Deficiency Symptoms However, these parasites tend to cause less severe disease in llamas and alpacas than in ruminant hosts. If the alpaca tests positive for CL, the pus in their abscesses can spread the disease to other residents. People who are deficient in selenium may develop various diseases. Advanced anemia in alpacas can lead to Bottle Jaw (see below). Affected alpacas will also have a much weaker immune system. A healthy alpaca has a bright pink eyelid.
