Valoración de la eficiencia reproductiva de cobayos mediante tres cruces entre la línea Perú, Inti y Andina, en la Granja Experimental Laguacoto II

The evaluation of the reproductive efficiency of guinea pigs through three crosses between the Peru, Inti and Andina lines in the Laguacoto II experimental farm, whose objectives were; determine the productive differences and estimate the heterosis in the crossing of the three lines of guinea pigs. For this investigation, a completely randomized block design (DBCA) with 9 treatments and 3 repetitions was used, with a total of 189 experimental units. The crosses were Peru x Peru, Peru x Inti, Peru x Andean, Inti x Inti, Inti x Peru, Inti x Andean, Andean x Andean, Andean x Peru and Andean x Inti, in the analysis of variance most of the variables gave highly significant statistical significance (**). In the results obtained from the crossing of the three lines of guinea pigs, the Peru x Peru line had an average weight and length at birth of 201.46 grams and 16.96 cm, its excellent weight gain and rapid growth make it superior to the other lines of guinea pigs, achieving superior results in most of the variables evaluated. The Inti line obtained similar results when crossing it with the Peru line, better weights and average lengths of 193.35 grams and 16 cm were obtained, but not when crossing with the Andean line, giving us lower results. The Andean line was characterized by its high prolificity, giving us averages of 3.71 pups per calving, leaving the Inti and Peru lines behind.
