Efectos de la suplementación de metionina, treonina y triptófano sobre el rendimiento productivo y la calidad de canal de los cerdos en crecimiento bajo condiciones comerciales de producción

Abstract: El objetivo de este experimento fue determinar si la suplementación de metionina, treonina y triptófano en la dieta de cerdos en crecimiento y engorde criados en condiciones comerciales mejora su rendimiento productivo (consumo de alimento, ganancia de peso, conversión alimenticia, calidad de canal) y si esta estrategia es viable económicamente. El experimento se desarrolló simultáneamente en dos granjas comerciales, con cerdos alimentados durante las etapas de inicio, desarrollo y engorde con una dieta contro… Show more

“…Baseline model predictions for farrowing rate (88%), farrowing interval (146 d), and litters per farrowed sow/yr (2.50), were similar to best-case values observed for PRRS-free real farm (88.7%, 146 d and 2.46; respectively), while other parameters, such as the number of piglets weaned per sow/yr (23.2), replacement rate (30%) and nonproductive days (47 d) were similar to mean values observed in real farms (23.1, 35.8% and 42.3, respectively) (supplementary data, section: Farm data). These performance parameters are also within the range of parameters reported previously for local pig farms (Salazar-Villanea and Dorado-Montenegro, 2018;Vargas-Céspedes et al, 2018).…”

“…In a second step, calculated outputs for biological variables in the baseline scenario were compared, when available, against real data from PRRS negative farms (supplementary material, section: Farm-data). Further comparison of results from baseline scenario was also performed against values reported in previous local studies (Salazar-Villanea and Dorado-Montenegro, 2018;Vargas-Céspedes et al, 2018). Calculated economic performance was compared to real data supplied by a local consulting firm (Arango-Trujillo, 2020) considering aspects such as distribution of costs and revenues, revenues/cost ratio and production cost per kg of carcass weight.…”
