| Abstract |
| The aim of the study was to determine development of secondary follicles, Secondary to Primary follicles ratio (S/P) in the skin of Raeini kids from birth to 105 days. Skin biopsies were taken from the left midside of each kid at birth and continued at 2- week intervals till 15 weeks.For follicular development study, was used a total of 34 Raeini male and female kids. The trial was conducted in Baft breeding station. The results obtained from Raeini kids showed that female kids had the overall mean higher S/P ratios than those of males in all 3.5 months of follicles sampling after birth (12.39 vs. 11.77). Follicles ratio continued to increase up to a maximum of two months and 45 days of age in male and female kids (12.98 vs. 13.88) respectively anddecreased thereafter in female kids up to 75 days and like male kids increased to 90 days. Development of the secondary follicles population continued until two months of age and reached 87%then, the increased rates was slowed down by three months and finally, ceased.The age which secondary follicles were able to produce most fibres, viz, reached the maximum maturity (98%), occurred at 90 days of age.Although, follicles count showed that to be most rapid during the first month of kid’s life. In Raeini kid’s 60% of secondary follicles were capable of producing cashmere fibre at one month. It was therefore concluded that the first month of Raeini cashmere kids’ life isa critical period to develop secondary follicles. |
