Abstract

This research involvedthe studyof supplementationofmesquite (Prosopisjuliflora) andGuasmo(GuasumaUlmifolia) incattlefatteningdual purpose. It was held inthe Cantonprovince of LosRiosQuevedoinINIAPExperimentalStation. Production rateswere evaluated over supplementing of carob tree (Prosopisjuliflora), andguazmo(GuasumaUlmifolia) in dual-purpose cattlegrazing. Experimentalmethod was usedtakingsamplesfor testing to determineits nutritional value. Later, rationswere formulatedfor different treatments whereproduction rates, weight gain, body condition, costbenefit were found. The materials used were12 animals, scales, office supplies, computers, printers, camera and food rations. The resultsobtainedinthe variableweight gainfinal valuewere 80.16kiloswithmoremesquitepasturetreatmentand52.83kilosforgrasscontrol treatmentonly. Nosignificant differenceswere reported.
