The optimal size of dairy farms in romania

, : The optimal size of dairy farms in romania. Taurine 6: 231-264

Data concerning the production in the main part of the state owned dairy farms in Romania allowed an analysis of the influence of the medium number of foddered cows on the milk production, calvings, manure, the number of reformed cows, the cost of production and the cost of milk. Subzones were considered in relation to the arable area of the farm, within the framework of the main cattle breeding zones: 81-100%, 61-80%, 41-60%, 21-40% and 0-20%. The animals production and reproduction capacity decrease when the cow-farms enlarge as does the quantity of manure. There is an increase in the optimal size of the farm when the arable land area increases. The farm optimal size increases with 6.5 cows when the arable land increases with 1%. The optimal sizes of the farms in the subzones whose weight of arable land are 0-20%, 21-40%, 41-60%, 61-80% and 81-100% is 156, 287, 418, 548 and 679 cows, respectively. The minimal milk cost for the farm optimal size increases when the arable land percentage decreases.
