The purpose of this study was to calculate costs of milk production, gross production value, gross margin, absolute profit, and relative profit of dairy cattle farms located in the provinces of east Mediterranean region of Turkey. Primary data were collected from 148 dairy cattle farms designated using the Neyman Stratified Sampling method through surveys. Dairy farms were classified into four groups according to the number of cows. The data belong to the 2012 production season. A single product budget analysis […]

An Outdoor Pig Production System (SISCAL), at the Experimental Station Agronomic Institute of Paraná State was used with the objective to determine the establishment and production costs of this system in the Southwestern region of Paraná. The SISCAL area was dimensioned to a 14 sows and one boar herd, which was divided in paddocks to separate the animals per physiological stage (reproduction, gestation and nursery). The establishment cost was based on the labor, material used for the system installation and […]
