It was found that the average of bibliographic references per article was 33.5. In addition, its distribution among introduction, Materials and Methods and discussion was 33.5. 20.5 and 46.0 % of the total, respectively, without significant effect (P&gt;0.10) of six years (2006/2011 and 2012/2017) in any case. This same comparison showed that the average publication date of the referred documents was 1996 and 1998 without effect of six years (P&gt; 0.10). In the publication chronology of the bibliographic references, there was not treatment effect (P&gt; 0.10), with an accumulated of 1.7, 5.6, 17.6, 35.0, 66.1 and 93.9 % of the total mentioned with an age of 1, 2, 4, 8 , 16 and 32 years old, apparently forming a temporary cycle. The polynomial link between age and accumulated percent was highly significant (R2, 0.999, P &lt;0.001). Eight years in referred publications could be a possible index that would qualify the bibliographic support of scientific articles, at least those similar to the bias selected in this research. Undoubtedly, more research is required to support this suggestion.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Se llevó a cabo un examen del status quo de las referencias bibliográficas en 12 artículos científicos seleccionados al azar y publicados en inglés en revistas de alto impacto, correspondientes al período comprendido entre 2006 y 2017. Los artículos versaban sobre la temática de usar recursos fibrosos en la crianza de cerdos. Se halló que el promedio de referencias bibliográficas por artículo fue de 33.5. Además, su distribución entre introducción, Materiales y Métodos, y discusión fue de 33.5. 20.5 y 46.0 % del total, respectivamente, sin efecto significativo (P&gt;0.10) de sexenio (2006/2011 y 2012/2017) en ningún caso. Esta misma comparación indicó que la fecha promedio de publicación de los documentos referidos fue 1996 y 1998 sin efecto de sexenio (P&gt;0.10). En la cronología de publicación de las referencias bibliográficas no se halló efecto de tratamiento (P&gt;0.10), con acumulado de 1.7, 5.6, 17.6, 35.0, 66.1 y 93.9 % del total citado, con edad de 1, 2, 4, 8, 16 y 32 años, formando aparentemente un ciclo temporal. La vinculación polinomial entre la edad y el por ciento acumulado fue altamente significativa (R2, 0.999; P&lt;0.001). Ocho años de edad en publicaciones referidas pudiera ser un posible índice que calificaría el respaldo bibliográfico de los artículos científicos, al menos los similares al sesgo seleccionado en esta investigación. Indudablemente, se requiere de más investigaciones para avalar esta sugerencia.]]></p></abstract>
