Livestock breed purity: Whose goal?

  1. 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. 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. 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. 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. 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
  6. 6. True-to-type Osmanabadi • Colour - Completely black - Black with brown stomach and underside of tail, brown markings from eyelids to mouth and on borders of ears - Slightly white or brown long hair on hind legs - Black ears or white spots on ears (morkani) • Horns - Backward and downward bending horns or polled
  7. 7. Non-true-to-type Osmanabadi Outward, upward horns White patches on head or other body parts
  8. 8. Non-Osmanabadi breed type • Local breeds (so-called non-descript (?)) • Osmanabadi crosses
  9. 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
