Creosote bush (Larrea tridentata) biomass as fodder for sheep

The aim of this work was to determine the effect of integrated diets with creosote bush (Larrea tridentata) biomass added as fodder for sheep on feed intake, weight gain, pH, rumen protozoa and concentration of Eimeria spp. oocysts in feces. The entire creosote bush plant was incorporated as fod...

description The aim of this work was to determine the effect of integrated diets with creosote bush (Larrea tridentata) biomass added as fodder for sheep on feed intake, weight gain, pH, rumen protozoa and concentration of Eimeria spp. oocysts in feces. The entire creosote bush plant was incorporated as fodder at 0 (control), 5 and 10 % (dry basis) in integrated diets, replacing sorghum straw. Diets were randomly assigned to 21 Rambouillet sheep (22.1 ± 1.7 kg live weight). The trial lasted 60 days. The sheep fed with 5 and 10 % creosote bush had lower (P<0.04) intake than the control. Weight gain, feed efficiency and rumen pH had values with non-significant differences. The number of rumen protozoa and oocysts in feces decreased (P<0.02) as the percentage of creosote bush in the diet increased. Therefore, the results indicate that it is feasible to use up to 10 % creosote bush biomass in sheep diets.

La identificación del efecto de dietas integrales con la adición de biomasa del arbusto de gobernadora (Larrea tridentata) como forraje para borregos sobre el consumo de alimento, ganancia de peso, pH, protozoarios ruminales y, concentración de ooquistes de Eimeria spp. en heces, fue el objetivo de este trabajo. Se incorporó como forraje la planta completa de gobernadora en 0 (testigo), 5 y 10 % (base seca) en dietas integrales en sustitución de paja de sorgo. Las dietas fueron asignadas aleatoriamente a 21 borregos Rambouillet (22.1 ± 1.7 kg de peso vivo). El ensayo tuvo una duración de 60 días. Los borregos alimentados con 5 y 10 % de gobernadora tuvieron menor (P<0.04) consumo que el testigo. Ganancia de peso, eficiencia alimentaria y pH ruminal tienen valores con diferencias no significativas. El recuento de protozoarios ruminales y de ooquistes en heces fueron disminuidos (P<0.02) conforme se incrementó el porcentaje de gobernadora en la dieta. Por lo tanto, los resultados indican que es factible utilizar hasta el 10 % de biomasa de gobernadora en las dietas para borregos.
