Item Evaluación de dietas arbustivas sobre el comportamiento productivo y etológico en gazapos (Cavia porcellus) desde el nacimiento hasta recría I(2024-02) Velasteguí Zurita, Enrique Ronaldo; Avilés Esquivel, Diana FernandaThe purpose of this research was to evaluate the productive and behavioral parameters in gazapos fed with bush diets, with an inclusion of 40% alfalfa (Medicago sativa), 40% chilca (Baccharis latifolia) and 40% dill (Anethum graveolens), thus forming T1, T2 and T3. Using a completely randomized block design and discrete focal sampling. Two stages were evaluated: lactation and weaning, with a duration of 15 days respectively, completing the study in 30 days. In the first stage (lactation), there was statistical significance in weaning weight, with the best treatment being T1 (263.51 g), over T3 (254.13 g) and T2 (231.25 g); no significant difference was found in the variable birth weight or weight gain at weaning. In the second stage (weaning), T1 (359.71 g) showed high statistical significance in weight at the end of rearing, over T3 (346.82 g) and T2 (330.47 g). Regarding feed conversion, T2 (3.42 g/g) stood out over TI (3.58 g/g) and T3 (3.68 g/g), weight gain at this stage was also better in T2 (99.22 g), over T1 (96.2 g) and T3 (92.68 g), finally, lower mortality was reported in T3 (0.7%). It was concluded that T1 showed better productive results over T2 and T3. The behavioral parameters that showed statistical significance in the lactation stage were: feeding and rest, in both cases, due to the influence of the mothers, through colostrum consumption and concentrate consumption. For the weaning stage, the three treatments behaved in a similar way, so that no significant statistical differences were reported among them.
