Inseminação artificial em jumentas nordestinas no Semiárido Paraibano.

Abstract

The objective of this research was to evaluate and compare the use of donkey semen using the thinner the milk powder (Kenney, 1975), cold temperature of 5 ° C in asses subjected to two treatments for ovulation induction. The samples were from two donkeys. The semen parameters were evaluated in a conventional way, 10 donkeys were used, divided into two groups, both inseminated using skimmed milk powder (Kenney, 1975). Groupl: using human chorionic gonadotropin (HCG) 1500 IU and group 2 : using 2500 IU of HCG. Pregnancy diagnosis was performed by ultrasonography using Chison device brand, model D-600 Vet with transrectal linear transducer and frequency of 5MHz, 16 days after the date of insemination, and if so, repeated at 45 days post insemination for the diagnosis of eventual embryonic death. The use of 2500 IU provided a pregnancy rate of 50% compared to 0% in the use of 1500 IU. Recommending the use of 2500 IU in the induction of ovulation in northeastern asses.
