Effects of slow release mineral-vitamin supplementation on some reproductive performance and wool characteristic in Farahani sheep and lambs skin follicles

In order to survey slow release mineral-vitamin boluses effects on reproductive performance, wool and follicle structure characteristics of Farahani sheep, 60 head ewes were divided into two control and treatment groups.
