Abstract

To evaluate the reproductive performance of Markhoz does in an accelerated kid production system (three kiddings in two years) and to compare with a conventional kid production system, 90 mature does in Sanandaj Breeding Station were monitored into three groups: 1-twice mating a year with hormone (CIDR and injection of 400-IU PMSG); 2- Twice mating a year without hormone; 3- Conventional system, once a year (control group). Data on pregnancy rate, twinning or prolificacy rate, litter size, fecundity rate, born kid crop and weaned kid crop and viability rate were calculated and analysis was performed with GLM process using SAS software. The parturition rate and fecundity rate of does in the experimental (1,2) and control groups was 2, 1.77 and 1.66, and respectively 3.43, 2.7 and 2.17 during the 24 months that had a significant difference (p < 0.05). Born Kid Crop and Weaned Kid Crop and weaning rate during 24 months in treatment 1 was significantly more than the treatment 2 and control (p < 0.05). Average of Born Kid Crop and Weaned Kid Crop per doe in the experimental groups and control was 2.95, 2.62 and 1.39 kg respectively, and 10, 8.01 and 7.67 kg respectively, that the differences between three treatment were significant (p < 0.05). The Net income of the implementation of reproductive treatments and three kiddings in two years was more than control treatment.
