The dairy farming sector of European Agriculture is currently under considerable economic pressure so the aim of each farmer should be to produce saleable milk, at the lowest cost. One important area of concern is the expenditure on hot water for hygiene, as to be acceptable to the buyer the milk must have a low level of contaminants. Clean milk is produced from clean, healthy udders by means of equipment which is adequately and appropriately cleaned. To facilitate this hygienic milk production most dairies are eguipped with heaters to provide water at 40°C (for cleaning udders) and 80- 100°C (for plant cleaning). The practice of udder washing is a subjective process as it depends on the operator's judgement of a 'clean' udder and his view of necessity. In England and Wales there are two only accepted methods of plant cleaning, circulation cleaning and Acidified Boiling Water (A. B. W.). Prior to the. audit described it was expected that water and electricity consumption for plant cleaning would be predictable. To date there has been little information on the volume and temperature of water used on commercial dairy farms and the electricty consumed to produce this hot water. It is therefore difficult for farmers to make informed judgement on methods of reducing their electricity costs. Thirteen farms in South Devon have been monitored, to establish current practice: farmers were questioned about their water use; electricity and water consumption were metered for two years; and cleaning practices were observed. This survey has revealed that many non-standard cleaning methods are used on dairy farms, making the prediction of water and electricity consumption difficult. The management of equipment has been revealed as the most important aspect in determining the energy used. A computer model has been produced to simulate water heating in the farm dairy, which can be used to advise farmers as to the energy cost of their cleaning practices. This model has .been successfully used on several of the farms surveyed, on one farm its use resulted in energy savings in excess of 400 kWh per month.

The purpose of this study is to estimate the effect of Ontario’s Nutrient Management Act (NMA) on farm level profitability of dairy sector. NMA came into force in 2003 and sets standards for the storage and handling of nutrients for regulating farms that fit certain criteria to reduce the risk of nutrients entering surface water or groundwater, especially for farms with herd size that can produce Nutrient Units above a certain level (i.e. 300 Nutrient Units). While the Act may affect its regulated farms by incorporating additional compliance costs, it may not have the same effect on unregulated farms. Increase in the weighted-average production costs of all farms may lead to elevated milk price within a national cost of production (COP) pricing formula for dairy industry. A theoretical framework that describes the pathway by which farms’ economic performance can be affected by NMA is developed in this study. To empirically test whether NMA has effect on farm level profitability, a RE model is estimated by using the unbalanced panel data from Ontario Dairy Farm Accounting Project (ODFAP) from year 2000 to 2010. The empirical results of this study indicate that NMA may not have statistically significant effect on the profitability of regulated farms with no less than 300 Nutrient Units (NUs). A discussion is further developed to take into consideration factors that may affect this empirical results. / OMAFRA funding code: 200222
