12. Veterinary ecology Society s increasing concern for the environment is influencing livestock production. Modern legislation makes it easier to take action against farmers who either consciously or accidentally damage the environment with dangerous chemicals or wastes of animal origin. Farmers are also responsible for any harm their livestock may do to other people or their property. Larger feeding operations have raised the problem of an increased concentration of animal wastes treatment and may be a frequent cause undesirable odours. Disposal of the waste in a manner that is not harmful to the environment or objectionable to the others living in the area may be problematic and farmers are obliged to handle animal wastes within laws and regulations to protect the environment. Animal manure should be handled so that odours, dust, flies, rodents and other nuisances are eliminated or reduced. The manure must not be allowed to be dumped into streams, rivers, lakes or reservoirs as it could result into health and safety hazard to humans and animals. A big effort is to prevent surface and ground water, too. Water pollution is a major issue regarding the best way to dispose of animal wastes. Waste water is contaminated by various pollutants as faecal bacteria, suspended solids, phosphorus, ammonia or biochemical oxygen demand. The last is a measure of the amount of oxygen-demanding organic matter in the water which if to high can decrease the level of oxygen vital to fish and other organism living in the water. Algae problems in water may be caused by contamination with phosphorus and ammonia contained in animal waste. These materials provide nutrients supporting excessive growth of this water organism. Finally, bacteria from the intestinal tracts of humans and animals present in waste water can transmit diseases to humans and animals. Selecting a system of manure handling is dependent on many factors, primarily on the animal species that is being raised. The ration fed to the animals as well as the type of housing and management also affects the characteristics of the manure produced. Climate as amount of rainfall, evaporation, the common direction of wind and temperature also play an important role. Animal manure can be collected and handled as a solid or as a liquid. Housing that uses a solid system may have concrete or slotted floors or solid floors with gutters. The others often have solid concrete or slotted floors that can be flushed with water. Liquid systems use pits, lagoons or storage basins for storing and handling manure. As a valuable fertilizer, most animal manure is eventually spread on the land. All solid handling systems work in this way and liquid system (except for lagoons) also involve moving the manure to a field to dispose of it. Conversely, animal manure can be the cause of undesired gases and odours which is caused by anaerobic bacteria breaking down the organic part. Such gases can be dangerous to people as well as animals and they should be controlled properly. Generally, they can be reduced by mixing air with the manure or using chemical and bacteria culture odour-control products such as masking agents, counteractants, deodorants or digestive deodorants. Disposal of dead animals should be made within a given period of time after death and in such a way that no hazard of spreading disease is created. Some of the common approved methods include a licence disposal plant, burying, disposal pits, burning or composting. The best place to dispose of fallen stock* is a rendering or disposal plant. Burning large animals seems problematic and smaller animals as baby pigs, or chicks are the only animals that are practical to burn. Commercial incinerators should be used. Burying animals requires the use of excavation equipment to dig a large enough pit. Carcasses should be placed in the proper depth below the surface and then covered with earth sufficiently. *fallen stock means animals which have been killed by euthanasia with or without definite diagnosis or have died (including stillborn and unborn animals) on a farm or any premise or during transport, but have not been slaughtered for human consumption
Water sampling and analysis Look at the Decision-making network for selection of method of analysis issued by the World Health Organization (http://www.who.int/water_sanitation_health/dwq/2edvol3d.pdf) and answer the following questions. 1. How should we transport the sample to laboratory if the sample is turbid? 2. What is the next step if the sample may not contain faecal bacteria but the analysis is required? 3. What is the limit of free chlorine to consider in a sample? 4. The abbreviation MPN stands for: minimal probability of nitrate or most probable number? 5. The abbreviation MF stands for or maximum filtration or membrane-filtration? 6. Explain the last box: on-site testing using MF in portable kits.
