Abstract: The forelimb bone of alpaca were studied by the method of gross anatomy, the comparative study with the forelimb of camel, equine, bovine, ovine, and swine were done at the same time. The result shows that the alpaca forelimb consists of scapula, humeri, 0ssa antebrachii(radius, ulna),0ssa Carpi,0s metacarpale,0ssa digiforum mamus. The composing and structure of alpaca are same to the bone of camel and similar with the bone of bovine, ovine, and swine in some degree. The alpaca scapula, and 0s metacarpale, 0ssa digiforum mamus were similar with the scapula of bovine. The humeri, 0ssa antebrachii(radius, ulna)were similar to the bone of equine. From above depicting and comparison, we concluded that the forelimb of alpaca were same with the forelimb of camel but smaller in form, were similar with the forelimb bone of equine, bovine, and ovine, were different to the bone of swine.
