El cruce Alentejano x Bísaro: un estudio en TREASURE

LBísara (BI) son las dos razas porcinas locales más importantes de Portugal, contando con un número de cerdas reproductoras de cerca de 6.500 (AL) y 5500 (BI) (datos de 2017, ANCPA y ANCSUB). Desde el punto de vista genético, fenotípico y de sistema usual de producción, son muy similares al cerdo Ibérico y Celta, respectivamente, de España. Así, la raza Alentejana es caracterizada por su baja prolificidad (Nunes, 1993; Charneca et al., 2012), crecimiento lento (excepto en montanera, Freitas, 1998) y tipo adipogénico (Neves et al., 1996). El cerdo Bísaro tiene mayor prolificidad (Carolino et al. 2009) y menor adiposidad, pero, aun teniendo el mismo origen genético de genotipos ahora usados en producción intensiva (ej. Large-White), no fue sometido a programas de mejora genética, lo que resulta en un cerdo cuya productividad está alejada de las razas mejoradas actuales. En la primera mitad del siglo pasado las razas de cerdos autóctonas eran predominantes en Portugal (el AL representaba cerca de 45% del efectivo porcino, Carvalho, 1964) distribuidos generalmente en el sur (AL) y en Centro/Norte (BI) del país. Sin embargo, en las regiones de coexistencia (en la región de Ribatejo, por ejemplo) los ganaderos hacían cruces entre las dos razas de forma común, para obtener productos que al parecer e r a n m u y a p r e c i a d o s . Desafortunadamente no hay información zootécnica sobre esos animales cruzados o sobre sus productos

Encuesta de datos demográficos y fenotípicos de razas locales de cerdos del proyecto TREASURE

The paper reports the results of a survey on the demographic and phenotypic characterization of 20 European local pig breeds involved in the H2020 TREASURE project including information on: demographic parameters, main morphological features, reproductive information, additional information collected at herd-level (i.e. temperament, holding, mating practices), origins and development of the breeds. Almost all the breeds (18 out of 20) possess a herd book even if the starting year is highly variable (from 1980 to 2006). Number of breeding females ranged from 24 (Moravka) to over 200,000 heads (Ibérico). Male/female ratio varied greatly with the highest values for the Italian breeds probably due to the different policy of animal recording. Almost all the breeds undergo a conservation program whereas really few are interested by other conservation techniques and for less than five breeds data related to effective number and inbreeding coefficient are easily available. Average values for teat number, litter size and weaned piglets are 12, 8 and 6 respectively with a great potential for their improvement. The depicted scenario is highly diversified and the data collected represent the starting point for the achievement of a collective trademark under the umbrella of the TREASURE project

Temperamento, instalaciones, prácticas de cubrición), orígenes y desarrollo de las razas. Casi todas las razas (18 de 20) tienen libro genealógico, aunque su fecha de inicio varía mucho (de 1980 a 2006). El número de hembras reproductoras varía de 24 (Moravka) a más de 200 mil cabezas (Ibérico). La relación macho/hembra varía mucho con los valores más altos verificados en las razas italianas muy probablemente debido a una política diferente relativamente al registro de animales. Casi todas las razas tienen programas de conservación, aunque pocas están interesadas en otras técnicas de conservación y sólo en menos que 5 razas los datos relativos a número de efectivos y de coeficiente de consanguinidad están fácilmente disponibles. Los valores medios para números de pezones, tamaño de camada y lechones destetados son de 12, 8 y 6, respectivamente con un grande potencial para mejora. El escenario descrito es altamente diversificado y esta colecta de datos representa el punto de partida para una marca colectiva debajo del parasol del proyecto TREASURE
