Viewed : 56 - Downloaded : 50 This experiment has been carried out to study the effect of the various level of feeding on the growth rate, live, weight, survival rate, reproductive efficiency, fleece weight, fleece shedding and the some properties of mohair in Angoras.

260 of male and 275 of female kids have been used for this experiment on the Çifteler State Farm in 1968. Each sex groups were divided into three ration groups. The animals were differently fed from weaning to 1.5 years old. But all males are sold at 1 year old. First group, which is called normal ration, Second group, which is called medium level ration, Third group, which is called low lovel ration pasture during summer.

The differences between first and other groups for live weight of 6 months, 1 year and 1.5 years were statistically significant in the both sexes. The were no clear significant between medium and low level ration groups in the same traits. The normal level ration group has more survival rate than medium and low level groups and also differences between of these froups were statistically significant in the 6 months and 1 year old animals. The survival rates of weaning have been seen high ratios in all groups because of kid loses were out of the experiment till this time.

The fibre diameter staple length and tensile strength have increased with normal level ration, but elasticity has decreased. The percentage of medullated and kempy fibre are not influenced by feeding.

Normal level ration has positively effected on the conception and parturition rates. The differences between first and other groups were statistically significant for the above characteristics. There were no any significant differences between medium and low level ration groups. It is suggested that has to be study in order to increase yearling`s fertility as well as life time fertility in Angoras.

The normal level ration group has shown earlier fleece shedding than medium and low level ration groups. Keywords :
