Follicular size predicts success in artificial insemination with frozen-thawed sperm in donkeys
In asses, semen collection, cryopreservation, and artificial insemination (AI) with frozen-thawed semen have been scarcely described and success rate, particularly following AI, is reportedly low. In the absence of reliable protocols, assisted reproductive technologies cannot support the conservation efforts aimed at endangered wild ass species and domestic donkey breeds. Two experiments were c...
متن کاملEffect of time and depth of insemination on fertility of Bharat Merino sheep inseminated trans-cervical with frozen-thawed semen
BACKGROUND Artificial insemination (AI) can serve as a powerful tool to the sheep owners for making rapid genetic progress of their flock. The AI in sheep is mostly performed using fresh semen with two reasons i) lambing rate following trans-cervical AI with frozen semen is limited by the inability of frozen-thawed sperm to transit the cervix and ii) the need of circumventing the cervical barri...
متن کاملEffect of sperm diluent and dose on the pregnancy rate in dromedary camels after artificial insemination with fresh and liquid-stored semen
Considerable scope exists for the use of AI in camel breeding programmes but the technology is not fully developed. The fertility of both fresh and liquid-stored (24 h; 4°C) dromedary camel semen diluted in either Green Buffer (GB) or INRA-96 (INRA) was assessed. Different insemination doses were investigated: 150 and 300 x 10 motile sperm for fresh sperm, and 150, 300 and 600 x 10 motile sperm...
متن کاملLaparoscopic Insemination of Sheep in Republic of Serbia
This paper describes a procedure of laparoscopic insemination (LAI) performed in 42 Ile de France ewes with deep-frozen rams’ semen. Frozen semen doses was imported from France, originating from two rams (A and B), and used intermittently in three LAI cycles on different females. The ewes were examined ultrasonographically for pregnancy, two months following insemination and data of lambing wer...
متن کاملArtificial insemination of frozen epididymal sperm in beagle dogs.
Freeze-storage of epididymal sperm is an important technique for the preservation of gametes in animals, including those becoming extinct. We froze canine sperm recovered from the cauda epididymis and investigated the fertility. The qualities of sperm from the cauda epididymis before freezing were: mean sperm motility, 89.4 +/- 1.6 (SE) %; sperm viability, 89.1 +/- 1.1%; and these were signific...
