“…Cashmere is always used to make luxury knitted fabric; thus, it has great economic value. The hair of the Cashmere goat is mainly divided into two types: guard hair produced by primary hair follicles and under hairs (referred to commercially as cashmere) produced by secondary follicles [ 1 ]. The hairs are highly similar in structure and composition but have notable differences in the degree of fineness, which is determined by each follicle's size and shape.…”

A Microarray-Based Analysis Reveals that a Short Photoperiod Promotes Hair Growth in the Arbas Cashmere Goat

Many animals exhibit different behaviors in different seasons. The photoperiod can have effects on migration, breeding, fur growth, and other processes. The cyclic growth of the fur and feathers of some species of mammals and birds, respectively, is stimulated by the photoperiod as a result of hormone-dependent regulation of the nervous system. To further examine this phenomenon, we evaluated the Arbas Cashmere goat (Capra hircus), a species that is often used in this type of research. The goats were exposed to an experimentally controlled short photoperiod to study the regulation of cyclic cashmere growth. Exposure to a short photoperiod extended the anagen phase of the Cashmere goat hair follicle to increase cashmere production. Assessments of tissue sections indicated that the short photoperiod significantly induced cashmere growth. This conclusion was supported by a comparison of the differences in gene expression between the short photoperiod and natural conditions using gene chip technology. Using the gene chip data, we identified genes that showed altered expression under the short photoperiod compared to natural conditions, and these genes were found to be involved in the biological processes of hair follicle growth, structural composition of the hair follicle, and the morphogenesis of the surrounding skin appendages. Knowledge about differences in the expression of these genes as well as their functions and periodic regulation patterns increases our understanding of Cashmere goat hair follicle growth. This study also provides preliminary data that may be useful for the development of an artificial method to improve cashmere production by controlling the light cycle, which has practical significance for livestock breeding.

“…The available data on weights of fleeces produced by Angora goats indicate that they are probably capable of rates of fibre production comparable to those of sheep. The rate of cashmere fibre production has not been studied, but maximum annual yields of cashmere from goats appear to be about 1 kg and are usually below 500 g (Burns et al, 1999;Von Bergen, 1999). This low production is partly due to inefficient harvesting and a period of follicle inactivity, as well as the fact that cashmere fibres do not represent the total production of the animal.…”

There are varieties of factors which can affect wool (macro and micro elements of wool) in sheep directly or indirectly. Genetic and environmental factors are major factors influencing wool quality and quantity. There are some bacterial, viral, fungal and espically parasitic diseases which also affect the wool. Other factors are exogenous chemicals, hormones, weather and photo period. In the present study, existing knowledge on the factors affecting wool were reviewed but there are gaps to conduct research on fundamental aspects of wool growth, which could have relevance to other areas of biology.
