Researches on Physico-Chemical and Microbiological Characteristics of Sheep and Cow Milk from Cristian Farm, Romania

Abstract

This study was conducted over a period of three month in the Cristian farm, Sibiu. For the physical, chemical and microbiological analyzes were taken a number of 15 samples per month. From physico-chemical point of view the content evolution of fat, not fat solid substance, density, protein, freezing point, temperature, lactose, conductivity, pH, water addition was followed. Samples were analyzed using the milk analyzer Ekomilk Total of the Research Centre in Biotechnology and Microbiology of the "Lucian Blaga" University. The microbiological contamination of milk was done by determining the total number of bacteria and coliform bacteria. From microbiological point of view it was observed that these conditions are largely met, but a more rigorous control on the cleanliness of utensils and of the staff is required.

The Influence of Microbiological Quality of Water Resources in Dairy Goat Farms

“…(Heathwaite et al, 2005b) (Pickett et al, 2001) The main sources of water pollution are defined as "any discernable, confined and discrete conveyance, including but not limited to, any pipe, ditch, channel...not including agricultural storm water and return flow from irrigated agriculture" (Edwards et al, 2008). Indeed, water quality plays for the farmers an important role in animal performance, nutrition and health (Davies-Colley et al, 2004) In recent years, efforts to improve water quality were focused on these sources (Steyaert et al, 2007) (Lengyel, 2012), because livestock need access to large quantity of clean water every day (Popa et al, 2014) It is necessary to ascertain if the activity of small farmers can compete favorably in the production of goat milk in good hygienic conditions, monitoring and analyzing the water samples taken from farmer's environment. (Monaghan et al, 2004) Without microbiological analysis of water, it would not be possible to determine the status and safety of drinking milk (Smith, 1993), which is so essential to establish the need and adequacy of treatment, and to safeguard human health (Devendra, 1982) This study will serve as an educational tool for the farmers, to change their breeding technology, looking forward to improve their dairy production.…”
