Livestock breed purity: Whose goal?

  1. Livestock breed purity: Whose goal? Chanda Nimbkar Nimbkar Agricultural Research Institute Phaltan, Maharashtra, India and Board member International Livestock Research Institute Public talk Arbaminch University, 11 April 2019
  2. Presentation to stimulate thinking • Does a livestock population have to be defined as a ‘breed’ to carry out its genetic improvement? • ‘Restrictive’ vs. ‘Inclusive’ uses of the ‘breed’ concept • What are the goals of the livestock keeper vs those of the scientists?
  3. Definition of a ‘Breed’ • Dictionary: A stock of animals within a species, having a distinctive appearance and typically having been developed by deliberate selection • Woolliams and Toro, 2007: ‘A breed is a breed if enough people say it is’. • FAO, 2007: ‘A breed is either a sub-specific group of domestic livestock with identifiable external characteristics that enable it to be separated by visual appraisal from other groups within the same species’.
  4. Flexible/Inclusive definition of a ‘Breed’ • A group for which geographical and/or cultural separation from phenotypically similar groups has led to acceptance of its separate identity. (FAO, 2007) • Excessive emphasis on finer points of phenotypic features is likely to leave large numbers of animals outside the purview of development projects, leading to a loss of genetic diversity.
  5. Latest tally: 34 registered goat breeds Total goats: 135 million Excellent adaptability (in their agro-climatic regions) and production potential but NEED effective, systematic breeding programs BUT 70% of the goats do not Belong to any of these breeds. They are ‘not described’ yet

  9. ‘desi’ or so-called non-descript animals (breed types) just as adapted and productive as ‘recognized’ breeds Breed type of does Number of does LSM ± s.e. True-to-type Osmanabadi (TT) 92 79.9 ± 4.7 Non true-to-type Osmanabadi (NTT) 169 87.1 ± 4.1 Non-Osmanabadi (NO) 186 87.4 ± 3.8 Least Squares Means of 100-day milk yield of does in three villages measured using the weigh-suckle-weigh method True to Type Non-True to Type Non-Osmanabadi
