Considered were four dairy farms. Two were certified organic farms and two were conventional – one with intensive and one with extensive production system. Observations were conducted on 10 Holstein-Friesian (HF) cows from each farm while from conventional farm with extensive production additional 10 Polish Red (PR) cows were observed. Samples of milk and hair for determination of minerals were...

The main purpose of this paper is to trace epistemological roots of conventional and Islamic finance.

This paper presents a game theoretic analysis of production structures including several stakeholders in the Japanese animation market and its related goods markets. We construct a decision-making model of the industry including players of four kinds: an animation studio, a broadcasting company, a related products manufacturer, and consumers. Additionally, we model two production structures: th...

The prospect of biofuel production on a large scale has focused attention on energy efficiencies associated with different agricultural systems and production goals. We used 17 years of detailed data on agricultural practices and yields to calculate an energy balance for different cropping systems under both food and fuel scenarios. We compared four grain and one forage systems in the U.S. Midw...

White (Lohmann LSL) and Brown (ATAK-S) laying hens, were reared under organic and conventional cage rearing systems, and the effects of the rearing system on performance parameters, egg production, egg characteristics, and immune response were investigated. For this purpose, a total of 832 laying hens of two commercial hybrids, i.e., 416 white (Lohmann LSL) and 416 Brown (ATAK-S) layers, were u...

This article reports the first publicly available egg production costs compared across 3 hen-housing systems. We collected detailed data from 2 flock cycles from a commercial egg farm operating a conventional barn, an aviary, and an enriched colony system at the same location. The farm employed the same operational and accounting procedures for each housing system. Results provide clear evidenc...
