A study uses ultrasound technology to advance the management of cattle farming by improving the quality of cows. Most domestic and foreign ultrasound research on cows consists of fragmented studies because of the difficulty in establishing standards for selecting quality cows using gathered information and genetic ability, and because it takes a long time to get results on genetic quality from future generations. Therefore, breeding farms in HongCheon, 434 houses and 6,543 heads of cattle, are given suggested selection and slaughter standards for their individual management. Using the results from estimating the genetic ability with ultrasound technology based on rearing capacity, the highest ranked 20% of the cows get continuous care and the lowest ranked 20% get rejected and shipped after fatting up. Based on these research results, the introduction of ultrasound technology is suggested as the way to apply a four-step classification for establishing a foundation for breeding cows. By suggesting a step by step detailed application method for producing and breeding the best cows, the goal is for the scientific society to present a method to secure income through continuous and stable breeding management.
