A Study of the properties of fiber in the goat crossbreds derived from Qom indigenous goats and Cashmere goats of South of Khorasan

This was a study to investigate quantitative and qualitative characteristics of fiber extracted from crossbred goats derived from female hair goats indigenous of Qom and male Cashmere goats of South of Khorasan. From a total of 75 indigenous and cross goats aged 1-3, qualities such as the percentage of cashmere in fleece, percentage of hair in fleece, hair staple length, cashmere staple length, cashmere fiber length, hair fiber length, and fiber diameter was investigated. Taking into account the effect of genetic group, sex and age characteristics, the data were analyzed with SAS software. The average fleece weight of goats was 300.2 ± 19.4 grams with a minimum of 99 and maximum of 713 grs. The length of hair fiber in the male goats fleece (12.8 ± 0.7 cm) was more than female ones (10.2 ± 0.5 cm); It was 12.0 ± 0 .6, 10.3 ± 0.4 and 12.2 ± 1.1 cm in indigenous goats, first and second generation cross goats respectively. The fleece weight in crossbred goats showed 21 grams increase compared to Qom indigenous goats; the difference was not statistically significant; While the percentage of cashmere in crossbred goats was almost twice as the indigenous goats (p
