This paper describes the optimization of a complex dairy farm simulation model using two quite different methods of optimization, the Genetic algorithm (GA) and the Lipschitz Branch-and-Bound (LBB) algorithm. These techniques have been used to improve an agricultural system model developed by Dexcel Limited, New Zealand, which describes a detailed representation of pastoral dairying scenarios a...

Understanding interactions between animals and humans is critical in preventing outbreaks of zoonotic disease. This is particularly important for avian influenza. Food animal production has been transformed since the 1918 influenza pandemic. Poultry and swine production have changed from small-scale methods to industrial-scale operations. There is substantial evidence of pathogen movement betwe...

The critics contend that today’s industrial agriculture is too dependent on fossil fuel, and too eager to ply consumers with cheap but nutritionally bankrupt calories. Among the critics, locavor...

The present work was carried out to study the mycobiota of cocoa beans from farm to chocolate. Four hundred and ninety-four samples were analyzed at various stages of cocoa processing: (i) primary stage at the farm (fermentation, drying, and storage), (ii) secondary stage at processing (testa, nibs, liquor, butter, cake and powder) and (iii) the final chocolate product (dark, milk, white and po...

Mastitis in bovine is an important disease in milk herds that cause economical losses due to decrease of milk production and treatment costs. Somatic cell count (SCC) is one of traditional test in mastitis diagnosis. The aim of current study was to evaluate the accuracy of udder check (on-farm) in comparison to SCC in industrial livestock. Current study was conducted in a 100 bovine livestock, ...
