Resumo
One experiment was conducted using 288 Isa
Babcock laying hens, to study the effects of beak trimming
(not trimming, light and severe). The hens were distributed in
an at random experimental design, in factorial arrangement
3x3 ( first x second beak trimming ). The first one was done at
nine days of age and the second at twelve weeks of age. Feed
intake, body weight, egg production and feed conversion in
four periods of twenty eight days each was evaluated.
According to the results, the birds at severe beak trimming
showed less feed intake and worst egg production (P<0.05).
