The most famous era of sheep breeding in Czech Republic is from the 2nd half of the 18th century to the 2nd half of the 19th century. In that time about 2.5 mil. animals were bred. The amount of sheep was reduced from 2.2 mil. in 1837 to 84,000 in 2000. Actually, 15 sheep breeds with 1,452 breeding rams are reared in our country. There are about 40 ewes for 1 breeding ram. The number of sheep in animal recording is increasing gradually, from 8,934 ewes in 1995 to 11,760 ewes in 1999. From 1995 to 1999 the conception rate improved by 5.7 %, the fertility increased by 2.9 % and the average daily gain in the age of 100 days increased by 29 g. The animal recording was performed by 9 authorized organisations in 1999. The dressing percentage, carcass composition and other parameters are evaluated in the frame of the breeding program.
