The present invention provides a genetic testing system that ensures complete traceability of animals and food products and involves a method of uniquely identifying animals for data collection, records management and retrieval purposes involving a novel method of genetic analysis using individual DNA fingerprinting of parentage of individual animal to effectively provide for full traceability of animals from birth to consumption.

System for tracing animal products

Disclosed herein are genetic markers for animal litter size, methods for identifying such markers, and methods of screening animals to determine those more likely to produce larger litters and preferably selecting those animals for future breeding purposes. The markers are based upon the presence or absence of certain polymorphisms in the prolactin receptor gene.

Prolactin receptor gene as a genetic marker for increased litter size in animals

Disclosed herein are genetic markers for pig litter size, methods for identifying such markers, and methods of screening pigs to determine those more likely to produce larger litters and preferably selecting those pigs for future breeding purposes based on the ESR polymorphisms. The markers are based upon the presence or absence of certain polymorphisms in the pig estrogen receptor gene. Preferably, the polymorphism is a restriction fragment length polymorphism (RFLP).
