2. Hide removal at slaughter. Defects on hides to be considered were an inner-side cut, a cut from inner
through outer side, and a line of vein.
3. Hide salting. Defects on hides to be considered were the rottenness of inner and outer sides.
A score level from 1 to 5 for each types of defects was used; 1=very good, 2=good, 3=fair, 4=poor, and
5 very poor. Each type of defects on every piece of hides was recorded. The ratio of hide numbers in scores 1 and
2 to those in scores 3, 4 and 5 for each type of problems was calculated as an indicators to compare the degree of
problems within the three original sources, then, the assessment of hide quality was graded into 3 as A (good), B
(fair) and C (poor) by experienced graders (Table 6).
The results showed that the degree of problems in the first lot was high in every source, the problems
due to hide removal at slaughter was highest, followed by on-farm management and hide salting. From the
traceability of problems on hides in lot 1, the requests to each operator for improvement were made. Positive
improvement of hide quality was shown in lot 2 and lot 3, but significantly higher in lot 2.

Conclusions and Recommendations
This operational research and development work had attempted to develop the quality hide clusters of
related operators in the transaction chain in order to maximize the use of hide resources for value added products
in the industrial sector. The research findings of this study supported the development of hide quality assessment
for improvement through the traceability of problems at original sources. The hide clusters consisting of the beef
producer cooperatives as the core link to farmers, slaughterhouse worker, hide collector, and tanner, showed a
promising trend for quality improvement of local hides. It was evident that the degree of problems from original
sources was lessened to some level during the period of study. The quality standard of KPS hide was formulated
for use in the future with the aim to relate quality assessment to the price of hides in the transaction chain.
