Researches on the Climate and Environmental Factors Influencing the Buffalo Cow breeding in North-West Romania

It was demonstrated that there is a direct correlation between the buffalo cow breeding and the size of the plastic and energy resources provided by forage and the preservation capacity of these resources. The efficiency of the metabolic transformations is optimum in a thermal neutrality environment as any stress of the thermo-regulating system is followed by increased energy consumption. The present paper approaches the correlation between climate and environmental factors and the amount and quality of buffalo cow milk. To assess the influence of climatic and environmental factors on the buffalo cow breeding, the average monthly, annual, and multi-annual values, as well as the minimum and maximum values of the temperature were analyzed during a 5 year period (2005-2009). Results showed a particularly negative influence on buffalo cow breeding due to environmental media during the breeding period and the grazing period

THE INFLUENCE OF WASHING PROCEDURE ON THE ANTIOXIDANT CAPACITY OF DAUCUS CAROTA SUBSP. SATIVUS

Carrots are in important source of antioxidants. The main compound that gives them antioxidant capacity is beta-carotene. Storage and post-harvest treatments can influence negatively the antioxidant capacity of carrots. In order to evaluate the impact of storage and washing procedure samples from Atomic Red and Royal Chantenay varieties were analyzed using Photochem instrument from AnalytikJena before washing, immediate after washing, after 15 day of storage at 8oC and after 45 day of storage at 8oC. The results are express in mg/kg equivalent TROLOX. There is a small loss of antioxidant capacity between the first day and after 15 days of storage, 3,86 % on average in the control batch respect to 9,47 % on average for the samples. Between the first day and after 45 days of storage there is a big loss of antioxidant capacity, 19,22% on average in the control batch respect to 24,86 % on average for the samples

EVALUATION OF THE IMPACT OF WASHING PROCEDURE ON THE THIABENDAZOLE CONCENTRATION IN SOLANUM TUBEROSUM

Thiabendazole (2-(1,3-thiazol-4-yl)-1H-benzoimidazole) is a fungicide used to ensure potato stability during storage. That is way it is manly found in stored potatoes. To see the impact of potato washing on Thiabendazole concentration samples from different varieties were extracted using dichlometane and analyzed by HPLC with florescent detection. The samples were analyses before and after the washing operation. The potatoes were washed using the CALIPSO Root Washing Module in which the washing procedure is done in the washing drum and on ramp witch has nozzles for additional washing. The levels of Thiabendazole found in the samples before washing were low. There was a decrease of 42 % of the Thiabendazole concentration in all samples after washing
