The Israel Johne's disease control program (IJDCP) is operating since 2003.

The program is voluntary and consist a herd management program and a whole herd testing by milk and/or serum Elisa and faecal culture of the seropositive or doubtful cows.

In the last 4 years 224 dairy herds were tested (42000 cows) for at least once.

The results of first testing indicate that half of the herds are lightly infected or not at all (0 to 2% seroprevalence). Some of these herds suffer sporadic clinical cases and had some positive cultures. 18% of the herds from the other half are considered heavily infected with 5% or higher seropositive cows, higher incidence of clinical cases and faecal culture positives.

Of the above mentioned herds 121 were tested twice or more in one year intervals. Most Herds with low (0-2%) prevalence in the first test maintained their status on the second test. Herds with medium (2-5%) prevalence didn't show marked improvement in the 2^nd test. A few High (5%<) prevalent Herds showed some improvement which thought to be technical due to selection of positive cows, but the true picture was seen in the third (or higher) testing.

Herds, which used a proper maternity pen, showed reduction from average of 4.6% in the first two tests to 3.4% positive seroprevalence in the 3^rd test while herds, which didn't do so increased their prevalence to 6.3%.

On national level there is some improvement concerning herd seroprevalece. There are 13% heavily (5%<) infected herds in comparison to 19% at start point.

These Heavily infected herds produced an average of 11423 L of milk in 2005 with 3.57% fat and 3.12% protein which is not different from the country average on the same year.
