  • Genetic markers for pig litter size
    Patent number: 5550024
    Abstract: 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).
    Type: Grant
    Filed: September 26, 1994
    Date of Patent: August 27, 1996
    Assignees: Biotechnology Research & Development Corporation, Iowa State University Research Foundation, Inc.
    Inventors: Max F. Rothschild, Christopher K. Tuggle, Carol D. Jacobson, David A. Vaske, Alan J. Mileham, Graham S. Plastow
  • Method for determining genetic marker for increased pig litter size
    Patent number: 5374526
    Abstract: 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. 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). A 3.7 kilobase fragment and a 4.3 kilobase fragment obtained by digesting pig genomic DNA with the restriction endonuclease Pvu II and detecting the fragments with a probe comprising a detectably labeled human estrogen receptor gene are associated with increased litter size.
