Abstract EN

The farming of dairy cattle is one of the pillars of the animal production sector projects in Egypt, where the value of the contribution of dairy production amounted to about 29,3% of the total animal production value in 2013, but the inability of distribute the highest productive types on the suitable production provinces leads to decrease the dairy production, where self-sufficiency in milk and milk products was estimated ratio of about 90% in 2013, so the aim of the study was analyze the differences between the types productivity of dairy cows in different governorates during the period (2011-2014), to optimize the quantities produced from milk cow, the study depends on the descriptive and quantitative analysis, tables and arithmetic mean, analysis of variance , and post hoc test (Duncan) to arrange different types of dairy cows, according to the productivity of the head, on the different provinces, as well as the use of linear numerical programming model for the redistribution of each type of dairy cows to the governorates of the initial Supreme ranked productive and determined in accordance with Duncan Test, The study found the following results : significant differences confirmed statistically in the productivity of dairy cows between different species, as well as between the various provinces, and there are significant effect statistically significant overlap between the species and the provinces, where dairy foreign cows ranked in the first with an average of about 3,4 tons / head, mixture cows of milk in the second place with an average of about 1,93 tons / head, and finally local milk cow's ranked the last with average of about 0,95 tons / head, according Duncan test results came in first place, according to the productivity of the head of foreign milk cows 16 governorate are Nubaria region and the provinces of Menoufia, Ismailia, Cairo, Elsharqia and Damietta and Qalyubia, Beheira, Sohag, Alexandria and Elgharbia , Qena and Assiut, Suez and Giza and Dakahlia, also there were 12 governorate ranked in the first according to the productivity of the head of mixture milk cows sush as Alexandria and Dakahlia and Elbehera, Qalubia and Elsharqia Giza, Damietta, Fayoum, Assiut and Menoufia and Elgharbia, Cairo , All the governorates except Minya and Luxor, Sohag and Qena ranked in the first according to the productivity local milk cow, as demonstrated by the proposed optimal distribution results that the percentage of the number of foreign dairy cows Reached to the maximum in Nubaria area with 63,6% from the total number of foreign milk cows Egypt, the proportion of the proposed numbers of mixture dairy cows reached its maximum in the Elsharqia governorate by 24,27% from the total number of mixture dairy cows, and the local milk cows proposed rate reached its maximum in Fayoum by 27,51% from the total number of local dairy cows, the expected production quantities after the re-distribution of cow milk on the first ranked provinces reached about 404,215,1 tons, with an increase in production amounted by 23,055,87 tons, so the study is recommended that, the important of re distribute the different types of dairy cows to first ranked provinces in order to achieve an increase in the quantities of milk,
