Resting behaviour of broilers in three different rearing systems
Zupan Šemrov, Manja, etologinja ...
The highest number of broilers is reared in the intensive fattening system on the floor with litter. Besides the intensive systems some sustainable rearing ways are also brought forward (ecoloogical, ...biologic-dynamic, organic, etc.). The aim of this study was to establish the possible differences in resting behaviour of broilers in three rearing systemcs: intensive on the floor, free range, and organic system. The results showed great varieties between intensive and and less intensive systems. In the intensive system on the floor animals rested statistically highly significantly more than in other two systems. Hovewer no differences in the behaviour of broilers in the stall were noticed, if compared to broilers in free range and those in the organic system. Comparison of the outdoor area showed that broilers rested statistically significantly more in the organic system. The reasons for different resting behaviour could be in leg weakness, body weight, group size, health problems, age, housing system, etc. Our research did not confirm our hypothesis that the older broilers rest more.
