Extract

The weight of secondary fibre (including fibre ˂18µ diameter (cashmere)) produced by goats differs greatly between genotypes. The reasons for such differences are unknown but may include differences in rate of growth, duration of the period of growth, the number of secondary hair follicles and fibre diameter.

Studies of the effect of dietary protein level on secondary fibre production have so far indicated that there is little potential for nutritional manipulation of fibre yield. However, these studies have been confined to breeds which have relatively low yields of fibre.
