Abstract
A computerized system for recording and calculating egg production, titled EGGSPERT, was developed to decrease the amount of time required for manual calculation of hen-day production. For 4 wk of production, hard-shelled (HS), soft-shelled (SS), shell-less (SL), SS + SL, and total hen-day egg productions were recorded and calculated both by hand and by the EGGSPERT system for 900 hens divided into 60 experimental units. Both methods of egg production analysis produced similar results with respect to HS, SS, SS + SL, and total hen-day production. However, analysis of SL egg production revealed a small, although significant (P < .05) increase of computerized recording when compared with the manual method of recording and calculating egg production (1.39 vs 1.31%, SEM = .03). A major advantage of the EGGSPERT system was a 6.4 h/wk decrease in time and labor required to total and calculate hen-day egg production when compared with the manual method of calculation. In conclusion, the EGGSPERT system was found to be a very reliable, accurate, and timesaving method for recording and calculating egg production.
