Abstract


An experiment was conducted wide strain cross White Leghorn layers (ILM-90) from 20 to  44 weeks of ,age to assess the effect of floor space levels on the production performance of birds raised on wire floors. Two levels of floor space viz., 470 and 700 cm2 per bird were studied. The overall mean hen-housed egg production was significantly higher (P< 0.01) with floor space of 700 cm2 per bird (60.27%) than those reared with floor space of 470 cm2/bird (51.81 %). The feed efficiency was better with a Floor space level of 470 cm2 -/bird than those provided with 700 cm2/bird floor space, but it was not statistically significant.Sexual maturity was attained earlier in flocks provided with more floor space. The mean body weight at the end of the experiment was higher in flock provided 700 cm2-/hird floor space than those provided 470 cm2 -/bird floor space. The mortality rate was numerically lass in groups provided more floor space. It was concluded that under wire floor system of rearing, laying hens required a floor space of 700 cm2/bird.
