1. A method for controlling sub-acute ruminal acidosis (SARA) in a dairy cow, the method comprising:
placing a pH sensor in a rumen of the dairy cow;
obtaining pH data of the rumen utilizing the pH sensor;
receiving the pH data by one or more processors;
calculating, utilizing the one or more processors, a first average of the pH data and a second average of the pH data, the first average associated with a first period of time and the second average associated with a second period of time;
generating, utilizing the one or more processors, a plurality of pH classes based on a plurality of predefined pH ranges, each of the plurality of pH classes corresponding to a respective predefined pH range of the plurality of predefined pH ranges;
generating, utilizing the one or more processors, a plurality of sodium bicarbonate classes based on a plurality of predefined sodium bicarbonate mass ranges, each of the plurality of sodium bicarbonate classes corresponding to a respective predefined sodium bicarbonate mass range of the plurality of predefined sodium bicarbonate mass ranges;
designing, utilizing the one or more processors, a fuzzy control system based on a set of rules, each rule of the set of rules comprising mapping a pair of pH classes to a respective sodium bicarbonate class of the plurality of sodium bicarbonate classes, the pair of pH classes comprising a first pH class of the plurality of pH classes and a second pH class of the plurality of pH classes, the first pH class associated with the first average and the second pH class associated with the second average, wherein the fuzzy control system comprises a first input, a second input, and an output;
determining an amount of sodium bicarbonate to add to a water supply of the dairy cow utilizing the fuzzy control system based on the first average and the second average, the determining the amount of sodium bicarbonate comprises:
loading the first average to the first input of the fuzzy control system;
loading the second average to the second input of the fuzzy control system; and
determining the amount of sodium bicarbonate by obtaining the output of the fuzzy control system; and
compensating SARA in the dairy cow by feeding the amount of sodium bicarbonate to the dairy cow.
