Morphological features of the udder of sows

On a livestock of pigs of different breeds for definition of possibilities of the forecast of dairy efficiency variability of morphological signs of separate shares of an udder is studied. Authentic distinctions in development of parametres (length, width, depth) separate shares of an udder of sows of a different genotype, age and constitution type that will allow to correct selection parametres at early age are established and to raise efficiency of selection of pigs on dairy efficiency.
