Abstract EN
This study was conducted at Fedio dairy station of the General Establishment for cattle (Ministry of Agriculture).
2296 productive records collected of 1037 from Holstein cows during the period 1989 to 2009 were used to determine thelength of dry period and study the factors affecting this productive parameter of Holstein cattle in Fedio dairy station.
The Data were exposed to GLM, Analysis of variance was used to determine the effect of calving year, calving season,parity and interactions in the drying period, and Duncan test was used to compare means by SPSS 17 program.
The overall mean was 103.35 ± 1.82 days and affected significantly (P< 0.001 ) by calving year, but there was nosignificant effect for calving season, parity، and interactions on the length of dry period.
It was suggested that better management and husbandry system as well as applying more efficient administration practices may reduce the length of dry period and increase economic efficiency of dairy cattle at Fedio station.
