On-farm research receives much attention from swine producers and industry professionals, and is often perceived by pork producers to be more relevant to real-world commercial pork production than controlled experiments conducted in university settings. Swine producers and industry professionals must realize that retrospective analysis can identify associations among variables of interest but p...

Animal welfare is of multi-dimensional nature, and its assessment should be based on a variety of measures. Traditionally, farm animal welfare assessment has focused on ‚inputs’ such as resources and management practices provided to the animals. Especially during the last decade, however, the use of animal-based ‚outcome’ measures has been advocated since they are considered to directly reflect...

To determine the water application efficiency in furrow irrigation more accurately, consideration of seasonal and spatial variation of infiltration properties are needed. In addition, the effectiveness of different farm management on infiltration are significant. The main objective of this research was to simulate the seasonal variation (SV) of infiltration coefficients in Kostiakov-Louise equa...

On-farm water storages (locally known as farm dams or farm ponds) are an important part of many agricultural landscapes, as they provide a reliable source of water for irrigation and stock. Although these waterbodies are artificially constructed and morphologically simple, there is increasing interest in their potential role as habitat for native flora and fauna. In this article, we present res...

must choose between higher average returns and lower risks. R management implies different things for different people, depending on their attitudes toward risk, their financial situations, and the opportunities available to them. In some cases, managing risk involves minimizing risk for a given level of expected output or revenue. In other cases, it involves keeping risk within bounds while se...

Increasing the inputs of nutrients has played a major role in increasing the supply of food to a continually growing world population. However, focusing attention on the most important nutrients, such as nitrogen (N), has in some cases led to nutrient imbalances, some excess applications especially of N, inefficient use and large losses to the environment with impacts on air and water quality, ...
