introduction
beef production in thailand is mostly regarded as supporting income for small farmers whereas crop production was considered to be a routine activity. from 1981 to 1987 the number of beef cattle increased 18.3 per year but this dropped rapidly to 2 since 1993 .problems associated with the sudden decline in beef population were due to the drop of the live animal value from the average price of 500,000 baht to only 50,000 baht for the good-looking tndu-brazil bull.
