Ovulation in camelids is induced by an unidentified protein in the seminal plasma of the male termed 'ovulation-inducing factor'. This protein has been reported to be a 14-kDa protein under reducing conditions, which, when purified from seminal plasma, induces ovulation in llamas. The identification of this protein and investigation of its potential to induce ovulation in camelids may aid the d...

Llama (Lama glama) and alpaca (Vicugna pacos) are the only large domesticated animals indigenous to the Americas. Pastoralism occupies a fundamental economic, social and religious role in Andean life. Today, camelid livestock are confined to the ecozone of the puna (above 3,500 masl), while their presence on the Pacific coast during pre-Hispanic times is attested by archaeological skeletal rema...

The development of assisted reproductive technologies such as embryo transfer (ET), artificial insemination (AI) and in vitro fertilization (IVF) in South American camelids is considerably behind that of other livestock species. Poor success of the embryo transfer technique has been related to a lack of an effective superstimulatory treatment, low embryo recovery rate, and the recovery of hatch...

The Ketamine Stun is simply the addition of a small dose of ketamine to any injectable chemical restraint technique. I initially developed the Ketamine Stun technique in the early 1990's to cover my limited cat handling abilities. My first exposure to camelid patients came when I left equine practice to teach at Ohio State. The recalcitrant behavior they frequently exhibited quickly led to expe...

INTRODUCTION Anthelmintic resistance is defined as “a greater frequency of individuals within a population able to tolerate doses of a compound than in the normal population of the same species.” 1 Anthelmintic resistance of gastrointestinal (GI) nematodes, particularly Haemonchus contortus, to commonly used anthelmintics has become a significant problem in small ruminants (sheep and goats) in ...
