    Efecto de leguminosas arbóreas sobre la preferencia de consumo en ovinos (Ovis aries)
    (2018) Chimborazo Azogue, Wilmer Hernán; Rivera Guerra, Verónica
    The aim of this investigation was to determine the intake preference of arboreal legumes in eight male sheep with average weight of 61,16 ± 3,3 kg. The following treatments were evaluated: Acacia melanoxylon (AM1), Acacia mearnssi (AM2), Acacia hayesii (AH), Senna muliglandulosa (SM), Caesalpina espinosa (CE), Genista monspessulana (GM). The voluntary intake preference was determined, through a cafeteria test. In situ ruminal degradability of MS and MO, though the technique that employs the nylon bag in the rumen Ørskov, Hovell, & Mould (1980). In vitro digestibility and gas production. The intake preference in the first phase showed significant differences (P<0.0001) among the legumes, with the highest intake the AM1, GM and AH. In the second phase, the highest (P<0.0001) intake was observed in the AM2 (32,0 gMS/day, 14,9 gMS/kgPV0,75 y 311,6 gMO/day, 14,9 gMO/kg PV0,75). Regarding the ruminal degradability of the MS in fraction A, the SM plant presented a higher percentage (56,3%), followed by CE with 48,4%, but statistically all the plants differ significantly (P<0.0001). Fraction B, the species with the highest (P<0.0001) degradation was AM2 (47,2%), followed by GM with 41,6% respectively. In Fraction c the data also differed significantly (P<0.0001). Something similar happened in the effective degradability. With respect to MO, in Fraction A with greater (P<0.0001) degradability was obtained in SM (54,6%), preceded by CE with 47,5% respectively. Highest (P<0.0001) digestibility was shown in GM, while higher gas production in AM1 and CE. It can be concluded that tree legumes such as AM1, AH and GM are a good alternative to incorporate in the sheep diets, since it has excellent voluntary intake and high protein level, which helps the digestive process.
