"The present study was conducted to study the shape of hair from genus Llama. The hair of llama was collected from animals fed in Japan and Peru. The hair of alpaca was collected from animals fed in Japan. The hair of guanaco and vicuna were supplied from the co-research member in University of National Agriculture La Molina. The hair of sheep (suffork) was collected from animals fed in our laboratory. Expansibility, number of crimps, thickness, and dimensions and form of cuticle were determined by optical and electron microscopic observation. The expansibility of hair from genus Llama was lower than that from sheep; conversely, the number of crimps in hair from genus Llama was higher than that from sheep. This suggested that the flexibility of hair from genus Llama is lower than that from sheep. The results of thickness showed that the crude hair from llama was 2-3 times higher than the other animals' usual hair. And the thickness of hair from vicuna was half the size of the other animals' usual hair. In the results of electron microscopic observation, the form of cuticle was classified into two groups, one of which showed the wide width type (llama, alpaca, guanaco and sheep) and vicuna showed the long length type. The hair of vicuna showed the lowest value of cuticle dimensions and the other animals' hair showed the nearly the same values without it being fed in Peru."
