      The aim of this study was to understand the benefit of diet mixing for Creole goats grazingnative forage species in the central Monte desert of Argentina and the drivers of preferencein the mixed diet. To achieve this goal, cafeteria-style experiments were conducted withthirty female Creole goats (2 years old; 44 ± 1.4 kg) and forage species that are typicallyingested by goats in this region: Two tanniniferous (Tricomaria usillo, Mimosa ephedroides)and three non-tanniniferous shrubs (Prosopis flexuosa, Capparis atamisquea, Atriplex lampa).In Experiment 1, goats were assigned to three groups (n ...

      Egea, Vanina; Allegretti, Liliana Inés; Páez Lama, Sebastián; Fucili, Mercedes; Morales, Melisa; Valli, Federico; Guevara, Juan Carlos (2016)
      En el NE de Lavalle la principal actividad productiva es la cría de cabras Criollas en sistemas pastoriles extensivos. La selección de dieta y la ingesta de forraje de las cabras varían según estado fisiológico y requerimientos nutricionales. Obtener estimaciones ajustadas del consumo, composición y digestibilidad de la dieta permitiría comprender las estrategias de pastoreo de las cabras y sus consecuencias para los recursos forrajeros de la región. Su objetivo es determinar consumo, composición botánica y digestibilidad de la dieta de cabras Criollas en diferentes estados fisiológicos ...

      The objective of this study was to determine the effect of the length of the suckling period and the dietary energy level on the duration of postpartum anestrus in Creole goats. Twenty-eight multiparous pregnant goats (bodyweight BW 39.9 ± 6.4 kg; mean ± SEM) each bearing a single fetus were used in a 2 suckling period (30 vs. 60 d) × 2 levels of energy intake (low (L) vs. high (H)) factorial design. Kids were separated from their dams 3 d after birth and then suckled twice per day until weaned at 30 or 60 d postpartum. Dams weaned at 30 d postpartum were hand milked for the next 30 d. Goats ...
