Vlivy působící na morfologické změny vemene u valašek
KUČERA, Josef
The morphological structure of the udder ofsheep is important due to the possible complications of lamb breeding and the use of machine milking. Bad teats position, short teats are problematic in lambing period and milking machin. Lambs can´t findt too big and horizontal teats.

The main objectives of this bachelor thesis are collecting and rating of cured meat sheep´s udder traits. Measurement on 107 sheep shows data which are focused on udder depth, udder width , teat lenght, teat position, udder attachment and udder cleft. Thereafter was assessed influence of litter chronological order on these values. Udder depth average is on level 8.2 centimetres. Udder width average is on level 9.1 centimetres. And teat length is in average 2.5 centimetres. All of these dimensions are growing up to the 4th littler. Since the 5th littler are measured traits in lower level. For the 6th and next litters are the explored values as same as the fifth´s litters. Point value of teat position was done on 2,93 points. It means that this value (2,93) is in suitable interval from 2 to 3, which is the best for lambs. Lambs can find teats without problems. Point value of teat position increases from the first litter (2,70) to the fifth litter (3,23) and then it continues on the same level. Udder attachment oscillates about 2,1 points (average) and there are no changes with chronological order of litter. Udder cleft is fixed on average value 3,84 points.
