The effect of weaning age on performance and nutrient digestibility of broiler rabbits
|Vědecké publikace impaktované
The effect of weaning age on growth, feed consumption, digestibility of nutrients, carcass yield, mortality and parasite incidence was studied in a balance experiment. Most results of performance were not significantly affected by weaning age. Higher digestibility of nutrients was recorded in the collection period from 56 to 63 days of age. In the collection period from 42 to 49 days, the digestibility of nutrients was higher in rabbits weaned at 25 days of age in comparison with the other groups. No differences between groups in the digestibility of nutrients were observed in the second period. The age of weaning did not influence carcass characteristics. There was no significant effect of weaning age on mortality. The incidence of Eimeria ssp. was the highest after weaning in rabbits at the age of 35 days.
