viABSTRACTA York-landrace pig producing process investigation in fattening stage was carriedout in the Pig Producing Unit of Escuela Superior Politecnica de Chimborazo,located in the city of Riobamba, Chimborazo Province. Different electrolyticbalances in diet were evaluated. Therefore, a random design was used during the120 treatment days. It was determined that pigs treated with 170 mEq/KgMs gotthe best final weight and weight gain producing parameters with an average of54.52% and 33.88 kg at the end of fattening stage. Besides, they got the bestnutrition conversion with an average of 2.81. It was also determined that pigstreated with 170 mEq/KgMs got the best producing profit with a final weight of89.95Kg and weight gain of 35.43kg. They also got the best nutrition conversionwith an average of 4.56, a carcass yield was gotten with an average of 91.12%and a benefit-cost index of 1.22USD at the end of fattening stage. It isrecommended to use an electrolytic balance of 170 M Eq/KgMs due to a quadraticfunction was the best 170mEq/KgMs treatment by reviewing the data gotten fromtreatments with 120, 170 and 220 mEq/KgMs. The electrolytic balance levels of120 and 220 mEq/KgMs decreased the producing parameters. Investigations withother levels must be carried out to determine the best toxic level.
