OBJECTIVES The three objectives of this study were to determine the positive predictive value (PPV) of oestrus diagnosis (heat detection accuracy) by dairy farmers, calculate the diagnostic sensitivity and specificity of the P4 Rapid milk progesterone assay for detecting a corpus luteum and evaluate the economics of using a cow-side milk progesterone assay designed to aid oestrus diagnosis. M...

Th e aim of the research was the comparison of economic feasibility of most common conventional and organic farm production in Slovenia. Th e methodology of an integrated deterministic technologic-economic simulation system KARSIM 1.0 (DSM) application for cost analysis and decision-making support on farms is described in this article. Th e direct simulation model result is an individual conven...

7 About 2% of English-language literature on plantations deals with mixed-species 8 plantations, but only a tiny proportion (<0.1%) of industrial plantations are 9 polycultures. Small landholders are more innovative, with 12% of Australia’s farm 10 forestry plantations under mixed-species plantings, and 80% of Queensland’s farm 11 forestry as polycultures. We examine reasons for this discrepanc...

The Agricultural Market Transition Act (AMTA) title of the 1996 FAIR Act is a novel departure in farm policy. Its fixed payments, no acreage set-asides, and avoidance of CCC commodity stockpiles provide a possible means of transition to a market-based agriculture that would not require governmental intervention to prop up the agricultural economy. Some now argue that the FAIR Act has failed, on...

Children comprise a significant portion of the agricultural workforce and are exposed to many workplace hazards, including farm machinery, pesticides, poor field sanitation, unsafe transportation, and fatigue from doing physically demanding work for long periods. Migrant farmworker children face the additional hazard of substandard or nonexistent housing in the fields. Children account for a di...

As part of the so called accompanying-measures of the CAP reform Council Regulation (EEC) 2078/92 was established in 1992. The goals of this regulation are to reduce farm output and/or to reduce environmentally detrimental side effects of farm production and/or to support farm income. This paper demonstrates how to use equilibrium-displacement models to analyse market effects of programmes that...

Long-term accumulation of soil phosphorus (P) is becoming a concern on some watersheds heavily populated with animal feeding facilities, including dairy farms. Management changes in crop production and feeding may help reduce the accumulation of excess P, but farm profitability must be maintained or improved to assure adoption of such changes. Whole-farm simulation was used to evaluate the long...

This study presents an econometric examination of the joint decisions of farmers on the adoption of a microcomputer and (or) purchased computers services. The characteristics of a farmer-schooling, age, off-farm work-are shown to be important variables for explaining the odds of adopting purchased computers services only, a microcomputer only, and both computer technologies. Adoption of compute...
