Improved farrowing rate using intrauterine insemination in sows

Conception 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 ...

A Comparison of Intrauterine and Cervical Artificial Insemination Catheters on Farrowing Rate and Litter Size in Artificially Mated Sows

Effects of intrauterine and cervical artificial-insemination catheters on farrowing rate and litter size

Materials and methods: Three hundred eighty-nine sows were allotted into two experimental groups by parity, body condition score, and breed-of-sire influence. Sow matings were performed using a disposable foam-tipped intrauterine catheter (IU, n = 193) or a cervical catheter (IC, n = 196). Total number of piglets born per litter was recorded, and farrowing rates were calculated after all sows h...

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...
