Poultry genetic resource conservation using primordial germ cells
The majority of poultry genetic resources are maintained in situ in living populations. However, in situ conservation of poultry genetic resources always carries the risk of loss owing to pathogen outbreaks, genetic problems, breeding cessation, or natural disasters. Cryobanking of germplasm in birds has been limited to the use of semen, preventing conservation of the W chromosome and mitochond...
متن کاملPoultry Genetic Resources and Conservation Biology
Recent generations of poultry students and poultry specialists generally seem to lack awareness of the vast genetic diversity which has accumulated in the domestic birds. This diversity has tended to become segregated within the realms of special purpose and special group such as industrial breeders and producers. There are many variants and variation in relation to species, body systems, and p...
متن کاملApplied reproductive technologies and genetic resource banking for amphibian conservation.
As amphibian populations continue to decline, both government and non-government organisations are establishing captive assurance colonies to secure populations deemed at risk of extinction if left in the wild. For the most part, little is known about the nutritional ecology, reproductive biology or husbandry needs of the animals placed into captive breeding programs. Because of this lack of kn...
متن کاملAnimal genetic resources conservation in the Netherlands and Europe: poultry perspective.
Increased global use of highly productive breeds of farm animals has been coupled to loss of genetic diversity in most species. In European countries, various governmental, non-governmental, and private organizations try to preserve genetic diversity of livestock in situ (e.g., by stimulating the use of indigenous, rare breeds by farmers; in nature reserves; or in noncommercial farms). In the c...
متن کاملThe role of antioxidants in reproduction and fertility of poultry
For the majority of organisms on Earth, life without oxygen is impossible. Animals, plants and many microorganisms rely on oxygen for the efficient production of energy. However, the high oxygen concentration in the atmosphere is potentially toxic for living organisms. Recently free radical research has generated valuable information for further understanding not only detrimental, but also bene...
