Abstract
This experiment was carried out to show a reform measures by grouping for problems by the survey of TMR plants. Twenty total mixed ration (TMR) plants (10 cooperation and 10 private plants) were surveyed, of which 13 plants, 65% of total TMR plants, committed TMR formulae to a outside nutrition specialist (TMR formulator). With respect to consulting fee for TMR formulae, $500{\sim}900$ thousands Won was paid monthly. On the basis of dry matter 1kg, the prices of TMR products were $325.6{\sim}347.0$Won, whereas those of wet TMR products $365.7{\sim}375.0$Won, which was appeared to be factors to increase management cost. And also, because the TMR plants did not provide TDN (total digestible nutrient) value on their products, nutritional balance feeding for cows could not be managed in farms. It was calculated, based on ADF (acid detergent fiber) value, that TDN value in dry type TMR was 63.0% and 73.2% fur private and cooperation TMR plants, respectively and that the corresponding figure in wet type TMR was 64.9% and 67.2%. According to TMR plant employee's opinion, a prier items to enlarge TMR utilization were TMR education, TMR advertisement, and improvement of ability to make TMR formula. Therefore, for the purpose of further development of TMR, special education of persons related to TMR should be supported.
