Breeding of genetic resource Bohemian Red cattle at the University Agricultural Enterprise, SBU in České Budějovice
ŤOUPALOVÁ, Michaela
At the turn of the 19th century a Czech red cattle, the breed, which was in our conditions bred a long time ago, was crossbreeding with a simen{\crq}s bull. Czech red cattle were gradually decreasing until now, when it is at the critical limit. At the 1991, in Department of Genetics, Breeding and Nutrition, at Faculty of Agriculture, University of South Bohemia, has begun regeneration of this rare, for our conditions original, breed. The Process of Bulls absorptive breeding of Czech red cattle has begun. Czech red cattle have by now more then 162 pcs. There are kept 43 head of cattle in the case of breeding under warranty ČZU Prague. JČU in Č.Budějovice has got 119 individuals under its guarantee, of which 60 is kept on the school farm Haklovy Dvory. At research was analyses data about growth and development of calves breeding without market production of milk and Data of cow milk efficiency breeding for milk production at stable manner. The highest milk yield was achieved at 173 days lactation. The Total quantity was 1 469 kg of milk. The highest average content of milk fat was 3,80 %, and content of milk protein was 3,52 %. Index of growth and development was calculated on age 120 {--} 210 days. Average weight of 4 cows at the age of 120 days was 114kg. The highest increase of weight was noticed at a bull {--} calf and was 934 g. Average weights of 2 pcs. on unified age 210 days was 221kg. The highest growth was achieved at a heifer with its 1 038g. Meanwhile analysis of genetic structure of population has begun and on the basis of results was characterized number of locusts and microsatellites at given population. Genotyping of locusts for DGAT, GH, b {--} LG, PRL, IGF BP3, PIT1, BLAD, LEP, DUMPS, b {--} CN, kappa casein, beta casein und ALFA S1 casein was performed in the set of 272 animals. Frequency was observed in microsatellites RM 012, BOVCASK 35, BOVIRP, BTO BCAM, BOVPAI, BOVSEMRN, SRC 97, IGF BP3, CSS 004, IDVG A - 9, BM 6117, BM 148, BM 4621,BM 6438, BM 2113, BM 1824, BPA, BMS1658, INRA 107, INRA 23, ETH 3, ETH 225, ETH 10, TGLA 122, TGLA 126 and TGLA 227.
