Summary

The Chato Murciano is the only surviving breed of pig of those historically farmed in the region of Murcia for their quality meat. At present, it is on the verge of extinction, having a population of only 260 reproductive animals. This paper describes the genetic studies made in the conservation and recovery programme of this breed of pig. A study of the morphological characterization of these animals was carried out first, measuring thirteen quantitative and six qualitative variables in a sample of 24 adult animals, 8 males and 16 females.

Subsequently, investigation was made of the consanguinity of the individuals and of the population as well as the future influence of inbreeding in each generation. Finally, the accuracy and precision of the heterozygote-excess method was evaluated using two data sets from the Chato Murciano pig. One data set is an original population and the other is a F3+F4+F5 generation of a line created from mating a Chato Murciano female with a Large White boar as part of an absorption programme based on backcrosses with Chato Murciano boars.

Resumen

La raza Chato Murciano es a la única raza porcina superviviente de aquellas que históricamente se criaban en la región de Murcia por la calidad de su carne. Actualmente se encuentra en vía de extinción, ya que su población consta de tan solo 260 reproductores. Este artículo describe los estudios genéticos realizados para la conservación y programa de recuperación de esta raza. En primer lugar se llevó a cabo un estudio de la caracterización morfológica de estos animales, midiendo 13 variables cuantitativas y seis cualitativas en una muestra de 24 animales adultos, 8 machos y 16 hembras.

Como consecuencia, se realizó un estudio sobre la consanguinidad de los individuos y de la población, así como sobre la influencia futura de la consanguinidad en cada generación. Por fin, la exactitud y precisión del método heterozigote-excess fue evaluada utilizando dos series de datos de la raza Chato Murciano. Una de las series de datos proviene de una población y la segunda es una generación F3+F4+F5 de una línea creada por el cruce de hembra de Chato Murciano con macho Large White como parte de un programa de absorción basado en retrocruzamientos con machos de Chato Murciano.
