Description: | |
In recent years has recorded high number problematically conceptioned dairy heifers and dairy cows with reproduction, production and metabolic disorders. This phenomenon influences all effectivity of dairy breeds breeding in the Czech Republic. Good reproduction ability is important presumption for prosperity of cattle breeding. Presented project is directed to evaluation of relationship of growth indicators during rearing of dairy heifers to development of their reproductive system, also to following dairy performance at first lactation, on evalution selected parameters (diameter, linear type traits, breeding value) on health, reproduction ability, longevity of dairy cattle in CR. Next on evalution of count of occurence of reproduction, production and metabolic disoreders of dairy cows on next lactation too. Aim will be reduction of the disorders in heifers and cows of dairy breeds, lower culling of the animals, elevation of exploitation productive potential and reduction of costs to rearing of heifers of these breeds. By virtue of obtained results will be suggested methodology for optimal rearing of Holstein and Czech Spotted Cattle heifers. |
