Monitoring the effect of different calcium levels on organism of hens in the first laying period

Popis výsledku v původním jazyce

The aim of the study was to evaluate some aspects of calcium metabolism in hens in the beginning of laying period. The study was conducted on 38 hen&apos;s hybrid Lohman Brown Classic. Birds were kept in individual cages and divided to two groups of 19 hens. Hens were fed by standard feeding mixture for hens with different contain of calcium (2,1% and 3,7% - L and H, respectively) and with 0.5 percent chromium oxide added as an indigestible indicator. The experimental period lasted from 17th to 24th weeks of age. A statistically significant difference (P &lt;0.05) was also recorded in the weight of the animals. Hens with 2.1% Ca in diet had higher live weight at the end of monitored period. In the monitored blood parameters was the statistically significant different (P &lt; 0.05) between L group and H group in the ALP parameter. Egg production was monitored daily and egg quality was analyzed once per week. The statistically significant difference (P &lt;0.05) between L group and H group was recorded for eggshell weight, % shell and shell thickness.
