Genetic diversity in farm animals--a review.
Domestication of livestock species and a long history of migrations, selection and adaptation have created an enormous variety of breeds. Conservation of these genetic resources relies on demographic characterization, recording of production environments and effective data management. In addition, molecular genetic studies allow a comparison of genetic diversity within and across breeds and a r...
متن کاملMolecular Markers for Fertility in Farm Animals
A genetic marker is a gene or DNA sequence with known localization on a chromosome. It can be de-scribed as a variation that can be measured or detected by a suitable method, and can be used subsequently to detect the presence of a specific genotype. Such variations occurring at chromosomal or DNA level can serve as genetic markers. The progress in development of molecular markers suggests thei...
متن کاملDigestion and metabolism of dietary fat in farm animals.
Fat digestion and metabolism differ widely between animal species. In ruminants, dietary fats are hydrogenated in the rumen before intestinal absorption so that absorbed fatty acids (FA) are more saturated than dietary FA. In non-ruminants, intestinal FA digestibility depends on the level of saturation of dietary FA. Fat supplementation of the diet of cows decreases milk protein and has a varia...
متن کاملInduced Termination of Pregnancy in Domestic Farm Animals
Induced abortion may be desired during a normal or abnormal pregnancy. The methods of induced abortion differ between species mainly because of different sources for progesterone production during pregnancy between species and within a species according to different stages of gestation. In cows and buffaloes, pregnancy can be effectively terminated from 5 to 150 days by administration of luteol...
متن کاملGenetic Variation in Disease Resistance among Farm Animals
This background study paper reviews the results of scientific investigations involving genetic control mechanisms for resistance/tolerance in farm animals to specific viral, bacterial, parasitic and prion diseases. The paper presents the most prominent documented examples for resistance/tolerance in cows, sheep and goats, pigs and poultry. The importance of genetically heterogeneous populations...
