Resumen
At San José in Morona parish, Tiwinzta canton, Morona Santiago province Charolais livestock mix breed feeding is based on the use of gramalote grass (Axonopus scoparius), and Marandu (Brachiaria Brizantha), under a grazing system using ropes in order to determine the best productive variable it was carried out this research called “application of Axonopus scoparius (gramalote), and Brachiaria Brizantha (Maradu), in two feeding systems in Charolais mix breed young bulls, grown and fattening stage”. Twenty young bulls with an average age of nine months were used distributing in four treatments: Rotational gramalote feeding system (T1), rotational marandu feeding system (T2), feeding system using ropes with Marandu (T3), and feeding system using rope with gramalote (T4), same which were statistically analyzed under a complete ramdomized block design, comparison among treatments according to Tukey (P<0,05%), and an analysis made by least significant difference for feeding and pastures factors. Concerning with the results, it was determined that the best final weight and total weight gain recorded of young Charolais bulls submitted to the feeding system using ropes with gramalote grass, with average values of 287,72 kg and 81,62 kg respectively; the best feed conversion of young Charolais bulls during the 180-day evaluation showed the feeding system using ropes with gramalote with a conversion rate of 13,31. Best indicator benefited cost showed in treated animals with the feeding system using ropes and rotational feeding system, both with gramalote grass, with results of 1,84 and 1,32 respectively. These values showed per each dollar spent when using these fattening systems in young Charolais bulls it was obtained a net profit of 0,84 and 0,32 dollars respectively. It is concluded that the best treatment was the grazing system using ropes with gramalote (T4). That is why, it is recommended continuing with this grazing system in a small amount of animals that does not require labor force
