    (2024-02) Garcés Garcés, Jorge Luis; Avilés Esquivel, Diana Fernanda
    This research evaluated the effect of shrub diets on the behavior and productive indices of fattening female guinea pigs (Cavia porcellus), using the following treatments: T1: alfalfa (M. sativa), T2: chilca (B. latifolia), T3: dill (A. graveolens) and a completely randomized block experimental design was used, which were established according to four weight ranges: B1: 750 -800, B2: 801 - 850, B3: 851 - 900, B4: 901 -950; in each block were administered the 3 treatments mentioned above thus obtaining four replicates per treatment, 72 female guinea pigs and 12 male guinea pigs were acquired and then distributed in each block, placing 6 females and 1 male per pool, the male remained with the females during the first 15 days of the research with the intention of evaluating the sexual behavior of the aminals. The behavior was evaluated by means of a filmic record during the 75 days of the research and the days and hours when there was more activity were selected for the elaboration of an ethogram recording each one of the animal's behaviors; while, for the variables of the productive indexes, records of weight, food offered, rejected and number of dead animals were filled in. The results for feed consumption were as follows: T1: 1922.39 g, T2: 1877.62 g, T3: 1803.16 g; weight gain reported T1: 376.38 g, T2: 303.33 g, T3: 262.38 g; and feed conversion was T1: 5.24, T2: 6.43, T3: 6.89; in addition, a mortality of T1: 4.16%, T2: 8.33% and T3: 8.33% was reported as a result of poor management of the animals. Despite this, it was not possible to demonstrate significant differences between treatments for both behavioral variables and productive indexes, thus concluding that non-conventional bush diets work adequately as a feeding alternative for female guinea pigs in the fattening stage.
