| Abstract | ||
| This experiment was carried out at Agargof Sheep Improvement Station, which belongs to the State Board of Agricultural Research, Ministry of Agriculture, through a period from September / 2008 to April / 2009.This experiment was done to compare the differences between natural insemination and artificial insemination in the vaginal, cervical and uterine through the cervix, using the diluted semen with sperm concentration of (300,250,150×106) sperm per ejaculate, respectively. Estrus synchronization was made for all the ewes (38 ewes) using vaginal sponges impregnated with 40 mg of fluogesterone acetate for 11-12 days. The percentage of ewes showed estrus was 97.3 and the lambing percentage in ewes of natural and artificial insemination in the vaginal and intrauterine were significantly (P<0.05) higher than those ewes inseminated artificially in the cervix, in spite of the absence of significant differences in lambing percentage between the natural and artificial insemination in the vagina and uterus, but was there is a tendency for higher lambing percentages in natural insemination (37.5, 30.7, and 33.3% respectively). | ||
