Forty-five extension packages in seven categories were developed, tested and disseminated in various target areas. Data on 492 crop-dairy farms were collected through a survey as a part of FSDP activities to assess the impact of these interventions. Each farmer was interviewed twice, once during 1993 to 1997 (before implementation) and another during 1998 to 2001 (after implementation). Data included only farmers who kept cropping land plus buffalo and / or dairy cattle in five different governorates, Damietta (DAM), Kafr El-Sheikh (KEI), Menoufeia (MEN), Daqahleia (DAQ) and Gharbeia (GHA). Two districts were sampled within each governorate, one had farmers collaborating with FSDP who got at least one package (Cd and the other non-collaborating farmers (did not receive any package (control group)). Cattle were of three genotypes, native, exotic and cross between them. Response indicators considered were daily milk yield UR - http://nile.enal.sci.eg/EALE/2007/EJAP/4407/2/121.pdf ER -
