Abstract

To make timing of artificial insemination (AI) relative to ovulation less critical, methods for prolonging shelf life of spermatozoa in vivo after AI have been attempted to be developed. Encapsulation of sperm cells is a documented technology, and recently, a technology in which sperm cells are...

Abstract

Introduction: Routine surveillance samples disclosed seropositivity to influenza A virus (IAV) in a Norwegian turkey breeder flock. Simultaneous reports of influenza-like symptoms in farm workers and a laboratory confirmed influenza A(H1N1)pdm09 (H1N1pdm09) infection in one person led to the...

Abstract

Background: A genome wide association study for litter size in Norwegian White Sheep (NWS) was conducted using the recently developed ovine 50K SNP chip from Illumina. After genotyping 378 progeny tested artificial insemination (AI) rams, a GWAS analysis was performed on estimated breeding values...

Abstract

The main goal for a boar stud is to produce semen without a health risk for the recipient (safe semen), semen with a high fertilising potential (good semen) and for a low cost (cheap semen). These three goals may often be contradictory, as health precautions and extensive quality control implies...

Abstract

The effect of vaginal and cervical deposition of liquid semen stored at room temperature on the fertility of goats was tested in a field trial in which 217 Norwegian Dairy goats aged between 6 months and 7.5 years from 14 farms were inseminated after natural oestrous. Cervical insemination with...

Abstract

The Norwegian Pig Breeders' Association is the only Norwegian swine genetic company, focusing on transfer of genetic material through semen, owned by the Norwegian pig producers. Norsvin was established in 1958, and has ever since focused on improving the genetic material through scientific based...

Abstract

Extension of storage time of living animal spermatozoa is of great scientific and economical interest for the breeding industry in Norway. The extension of storage time will leave room to maneuver due to the time limit of artificial insemination of the animals. The aim of this study was to...

Abstract

In beef cattle production use of artificial insemination (AI) is generally low, and sires in natural mating are often used in only one or a few herds. Lack of connectedness among herds may occur, causing bias, low precision of genetic parameters and reduced accuracy of predicted breeding values. In ...

Minimum requirements for use of artificial insemination in beef cattle populations with small herds in Norway, 2007, pp viii + 103 pp.
Abstract

Artificial insemination (AI) in sheep is currently limited by the poor fertility obtained following non-surgical intracervical insemination of frozen-thawed semen. An exception to this general finding is the non-return rate of around 58% reported for large scale on-farm AI in Norway. The objective...
