Effects of interaction of breed by pen and cage position on hen day lay of layer breeds in the derived Southern Guinea Savannah of Nigeria.

Abstract

Egg production of Haco black, Shavers brown, Olympia black and Lohman Brown were collected from production records at Big Bam commercial poultry farm, Makurdi, from 1997 to 2004,in an experimentin which Pen location was designated as ‘ L’ and mean cage position as ‘C’,the mean hen day lay of the breeds were estimated in percentages. This were subjected to a two way Analysis of variance to determine the effect of breed by pen and cage interaction on hen-day performance.Mean hen day lay of Haco black by pen interaction was not significantly (P>0.01) different in pen L1 and L3, while that in pen L2 was low and significantly (P0.01) different while that due to pen L1 was lower and significantly (P
