The main component of the body: the water, alongside with many function which it has,represents a constituent in the diet of animal. There are many and various factors that influence the daily water requirements of animals: some dependent on animal: and others dependent on the environment. Water quality administered to livestock must meet the requirements for potability prerequisite to maintaining the health, externalization full productive potential and sustaining breeding. Knowing the importance of water quality consists in the negative action which can exert on the body to exceeding certain thresholds translated through: reducing water consumption simultaneously with the decrease milk production, decreased feed conversion rate and average daily gain, degradation of health status by reducing the local resistance, decrease overall body resistance, metabolic, digestive, skeletal disorders and impaired reproduction sphere translated through:decreasing fertility, abortions; elements interfering with the absorption of other essential water body, producing chronic or acute poisoning. The water composition plays essential role depending on which is supplemented or not as the case the quantity of the macro and trace minerals from feedingstuff according to the synergism or antagonism action between the minerals present.
The study was performed in 63 wells which belong to the decentralized system from 5 counties from Romania: AB-7 wells, BZ-6 wells, CJ-33 wells, MS-1wells, SJ-6 wells taking into account chemical parameters: nitrites (SR ISO 6777:1996)
Aim of this study was to assess the chemical status of water by point of view of the indicators parameters coming from the decentralized system of water supply (wells) and which supply with water the dairy cows farms. Study was performed in 63 wells from the same number of farms from 5 counties located in: S-E, N-W and central of Romania at the request of farmers. It has been studied the parameters that indicate the status of water acidification: pH (SR ISO 10523:1997
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
