Title: Recovery of ova and their re-insertion into the hen's oviduct through a fistula. Author: Pancer Z, Snapir N, Robinzon B, Friedman A, Eyalgiladi H. Journal: Br Poult Sci; 1989 Dec; 30(4):953-7. PubMed ID: 2627669. Abstract: 1. The first loop of the domestic hen's magnum was fistulated. A cannula mounted with a collecting tube served to trap the passing ova about 2.5 h following ovulation. 2. Nine out of 10 fistulated hens resumed ovulation about 2 to 5 weeks following surgery. A total of 63 magnal ova were collected. 3. Five of the magnal ova were successfully returned to the oviduct through the fistula and resulted in 5 normal soft-shelled eggs. The success of ova reimplantation was affected by prolapse of the posterior part of the oviduct and the timing of ova return.[Abstract] [Full Text] [Related] [New Search]
