| description | The relationship between levels of infection with gastrointestinal nematodes expressed in eggs per gram counts (e.p.g) and categorized as negative, light, moderate and heavy, were analyzed by multivariate analysis of simple linear correspondence and the following results were obtained: The Bergamasca´s daughters were associated with light to moderate level of infection, while in the case of the Barbados Black Belly 1 (BBN 1) daughters, it was found an association with a negative level of infection. The daughters of the Barbados Black Belly 2 (BBN 2) were associated with heavy level of infection. When analyzing each sire breed with their infection levels, it was found that: the Bergamasca sire was associated with a moderate levels of infection, while the Barbados Black Belly 1 (BBN 1) showed infections levels oscillating from light to moderate. The sire Barbados Black Belly 2 (BBN 2) showed a good correspondence with heavy levels of infection. In conclusion, knowing the e.p.g count is a phenotypic expression of resistance to parasitic gastrointestinal infection, that is genetic in nature and therefore heritable. the selection of sire Barbados Black Belly 1(BBN 1) is discussed and proposed. The sire with the highest capacity Helminth Resistant was the BBN1 |

Análisis de correspondencia Ovinos Helmintorresistente. The relationship between levels of infection with gastrointestinal nematodes expressed in eggs per gram counts (e.p.g) and categorized as negative, light, moderate and heavy, were analyzed by multivariate analysis of simple linear correspondence and the following results were obtained: The Bergamasca´s daughters were associated with light to moderate level of infection, while in the case of the Barbados Black Belly 1 (BBN 1) daughters, it was found an association with a negative level of infection. The daughters of the Barbados Black Belly 2 (BBN 2) were associated with heavy level of infection. When analyzing each sire breed with their infection levels, it was found that: the Bergamasca sire was associated with a moderate levels of infection, while the Barbados Black Belly 1 (BBN 1) showed infections levels oscillating from light to moderate. The sire Barbados Black Belly 2 (BBN 2) showed a good correspondence with heavy levels of infection. In conclusion, knowing the e.p.g count is a phenotypic expression of resistance to parasitic gastrointestinal infection, that is genetic in nature and therefore heritable. the selection of sire Barbados Black Belly 1(BBN 1) is discussed and proposed. The sire with the highest capacity Helminth Resistant was the BBN1 Mediante el análisis multivariado de correspondencia lineal simple, se evaluó laasociación entre los niveles de infección por nemátodos gastrointestinales, expresados en recuentos de huevos por gramo de heces (h.p.g.) y categorizados como Negativo, Leve, Moderado y Alto, tanto de las hijas agrupadas por padrote, como de los padrotes. El padrote de raza Bergamasca se asoció con hijas con niveles de infección leves o moderados, mientras que uno de los padrotes de la raza Barbados Barriga Negra, el BBN 1, se asoció con hijas negativas a la infección por estróngilos digestivos, y el otro (BBN 2), con niveles altos de infección de sus hijas. Al analizar cada padrote con sus respectivos niveles de infección se ve que el padrote Bergamasca se asocia con niveles moderados de infección, mientras que el Barbados Barriga Negra 1 (BBN 1) lo hizo con niveles de infección que oscilan entre leves y moderados. El padrote Barbados Barriga Negra 2 (BBN 2) mostró buena correspondencia con niveles de infección altos. Los resultados obtenidos evidencian una buena asociación entre los niveles de infección observados en los padrotes y el de cada lote de hijas separadas por cada padre. Conociendo que el recuento de h.p.g es una expresión fenotípica de resistencia frente a la infección por estróngilos digestivos, característica de índole genética y, por consiguiente heredable, concluimos que el padrote que expresó mejor capacidad helmintorresistente fue el BBN 1.
