Fertilization Rate and Number of Embryos on Day 2 after Intrauterine and Deep Intrauterine Insemination Using Frozen-Thawed Boar Semen in Multiparous Sows
The present study determines fertilization rate and number of embryos on Day 2 after intrauterine insemination (IUI) and deep intrauterine insemination (DIUI) using frozen-thawed (FT) boar semen in multiparous sows. Twelve crossbred Landrace × Yorkshire multiparous sows were included. The sows were inseminated at 24 h after oestrus detection and reinseminated every 12 h until ovulation took pla...
متن کاملConception Rate and Litter Size in Multiparous Sows after Intrauterine Insemination Using Frozen-Thawed Boar Semen in a Commercial Swine Herd in Thailand
The aim of the present study was to determine the conception rate and litter size in sows after fixed time intra-uterine insemination using frozen-thawed boar semen in a commercial swine herd in Thailand. Sixty-nine Landrace multiparous sows were randomly allocated into two groups, including control (n=36) and treatment (n=33). The control sows were inseminated with extended fresh semen (3 × 10...
متن کاملUse of frozen-thawed semen aggravates the summer-autumn infertility of artificially inseminated weaned sows in the Mediterranean region.
Improvement of farrowing rate (FR) and litter size (LS) of sows that are AI with frozen-thawed (FT) semen can hardly be reached without identification of the factors behind the high variability seen among trials. Three experiments using weaned (4-d wean-to-estrus interval) multiparous (parity 2 to 7) sows were conducted to evaluate the effect of period of the year on FR and LS of FT-inseminated...
متن کاملConception Rate, Farrowing Rate and Litter Size after Intrauterine Insemination with Cryopreserved Boar Semen in Spontaneous and Induced Ovulation Sows
Introduction The procedure for artificial insemination (AI) in pigs using cryopreserved semen involves the deposition of a high number of cryopreserved spermatozoa (5-6 x10 cells) in a large volume of diluent (80-100 ml) into the cervix. Despite inseminating with this high sperm number, low fertility levels are usually obtained (about 20-30% conception and farrowing rates and 2-3 total piglets ...
متن کاملUse of Boar Spermatozoa for Artif Icial Insemination. I. Fertil Iz Ing Capacity of Fresh and Frozen Spermatozoa in Sows on 36 Farms 1
A field trial was conducted on 36 farms in the Netherlands to compare the fertilizing capacity of fresh and frozen-thawed boar spermatozoa. Four-hundred and fifty-one sows were artificially inseminated with semen that had been frozen and thawed according to the Beltsville Method or diluted in Kiev extender and inseminated on the day of collection. Twelve boars of the Dutch Landrace and Dutch La...
