Abstract
Study on monality of Mecheri sheep was carried by analysing data of Mecheri Sheep
Research Station, Pottaneri, Tamil Nadu covering a period of 23 years. The overall mortality
rate in Mecheri sheep ranged between 3.03 and l9.95 % with the mean value of 9.8l % over
the years. The death rate was highest in 0-3 months. 3-6 months and above six years age
group and they were considered as the most critical periods with respect to mortality. The
mortality rate in summer, southwest monsoon. northeast monsoon and winter were 24.20,
29.6l, 18.34 and 27.85 %_ respectively. The death of the animal due to respiratory and
gastro-intestinal tract causes was maximum accounting for 33.48 and 33.03 % mortality in
different age group. Improving lamb management and proper care of pregnant and lactating
ewes could minimize the mortality rate in young animals and a sound culling policy for
adult ewes aged more than the six years would he of help in reducing the mortality in the
adult animals.
