Wiil is considered as one of the mest important el.ement inhu.m.a.n diflt, since it conta:i.nsthe essential f’::od nutriemtsneeded by children, adults and older people 0 It is genera1.~-,~rcomposed of body building proteins, bone bUlldll~ calcuim)health promoting vitamil,s and mineral saltS, and energy producingsugar 84d fats.Fr$ID the economoc point of view, milk production contributesconsidera; bly to the animal pr~ductj-~n i~c0me ~d consequentlYto the ~ricul tural. income. ; ~ Egypt, the level of ~ilk prnd~ction haS been raisedI during Ithe last 2 decades, but it is still lower than in thedevelo~ci d countriesl In spite of the achieved increase in theyearly Ii amourrt of milk produc tion;>e:rol>pitc e-m sumption is lowand betOW the standard. Statistical studie~ showed that thisestimafie decreased from 48.62 Kg in 1968 45.4 Kg in 1978 andis exprcted to be reduced to 43.6 Kg iL 1990 and to 42.5 KZin 20qIO~ This decrease in milk percapita consumption is mainly! due ti’ the rapid increase in the EgYl!tion human population.All t ese observations called for giving much efforts toincre se milk productivity of different ~_ivestock specieswhichi contribute to mt.Lk pron.ucti.on -i 1’1 tl-J..is country specially Due’ to the fact that 90 % of the local dairy cattle areovmed b,y; farmers, .the extension orgailization tried its bestfor raising the effeciency of milk production by encouragingfarmers to use Friesian bulls in crossbreeding their oows,toartificially insiminate them using Friesian Semen and to plantNapier Grass for feeding their dairy cattle in pummer.In~pite of the efforts made by the extension organizationin impr~ving the productivity of local dairy cattle, it isstill Ln ferior than that of european catt:le in the develppedcoUntries.
