Abstract | The objective of this study was to confirm the effect of negative energy balance (NEB) of the mothers around conceiving on the start of reproduction functions in their daughters. There were evaluated 44 Czech Fleckvieh and Holstein heifers and their mothers. Statistically there were no differences in the age of puberty onset between the heifers whose mothers were in NEB or not. But the tendency to be younger at the puberty onset had the heifers whose mothers were not in NEB. Therefore the repeated field experiment on more animals would be necessary. |
