Abstract

Cleft lip and jaw belong to congenital craniofacial abnormalities reported in all domestic species and humans as well. This malformation can be caused by genetic or environmental factors. A lateral cleft upper lip and jaw in conjunction with campylognathia has been observed in two Vorderwald cattle ...

Abstract

The use of sexed semen in artificial insemination of animals can offer multiple benefits in breeding programmes, animal trading, reproduction, animal health, and biodiversity. A commercial application of selecting spermatozoa with X and Y bearing chromosomes in high speed flow cytometer has only...

Abstract

Modern molecular biotechnology has been implemented in conventional animal breeding by development of DNA analytical methods and establishment of genetic engineering. The sector of biotechnology has a great innovative potential and has developed a major economic importance. Associated with high...

Abstract

The most efficient way to shift the sex ratio of offspring is to select spermatozoa according to the sex chromosomes. The difference in their DNA content can be determined by flow cytometry to produce populations of either sex at high accuracy. As the method is based on single cell identification,...

Abstract

Established reproductive-biotechnological technologies such as artificial insemination (AI) and embryo transfer (ET) employing in vivo produced embryos are already valuable tools for the maintenance and improvement of the health status of livestock populations. Transmission of pathogens can be...

Abstract

This paper discusses the value of conventional and new techniques as indicators of the fertilizing ability of spermatozoa. The classical assessment of sperm motility and morphology allows a rough estimation of semen quality to be made in order to select ejaculates for use in AI. Newer techniques,...

Abstract

This discussion focuses mainly on AI, the transfer, deep freezing, micromanipulation and sexing of embryos, and gene transfer. In Germany, the adoption of new biotechnological techniques is hindered by exaggerated attention to safety aspects, which has resulted in undue legal constraints, and the...

Abstract

In 1990, the number of cows inseminated in France increased by 2.47% to 5 630 846. Beef bull semen was used for 30% of inseminations. The most popular bull breeds were Holstein, Charolais, Normande, Montbéliard, Limousin and Blond d'Aquitaine, accounting for 49.1, 14.9, 11.3, 8.0, 6.8 and 4.8%...
