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

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 ...

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...

Abstract

Relationships between light exposure, milk yield, and reproductive traits in Norwegian Red cattle were studied using data from 1538 farms in southern Norway during the darkest part of the year (November 1 to February 28). Production level was expressed as milk yield at first artificial insemination ...

Abstract

East Friesian (EF) dairy sheep were introduced by insemination with semen from 4 rams from Sweden into 2 crossbred research flocks (Dala sheep with varying proportions of Finnish Landrace) of the Agricultural University of Norway in 1985 to improve milk yield and maternal ability. The 2 research...

Abstract

In 1996, in Norway, the number of 1st inseminations of cows decreased by 4166 (1%) compared with the previous year. Around 96% of cows were inseminated, mainly with semen from Norwegian Red, Swedish Red-and-White, Finnish Ayrshire and Swedish Lowland [Swedish Friesian] bulls. There was a decrease...

Abstract

In Norway, in 1995, there were 27 567 herds of Norwegian Red cattle, representing a decrease of 1.5% compared with the previous year. Of 420 430 cows inseminated, 96.4% were inseminated with semen from NR bulls, and semen from beef, Telemark, Blacksided Trondheim and Jersey bulls was used to...
