Comparative Efficiency of Various Disinfectants Used in the Cattle Farm

Abstract

The investigations were aimed to establish the comparative efficiency of four disinfectants (Aquadez, Ecocide S, Virocide and Na OH) used for the disinfection of cattle farm of State Agrarian University of Moldova. According to the classical methodology, the disinfectants have been used in concentrations which were recommended by the producers. Following this, lavages were collected from different supports and equipment of the cattle farm before sparing of the disinfectants and one hour after the contact of the disinfectants with the substrates. In this context samples were taken from places as the feeding space for animals and the rest area, cows’ milking rooms and the milk collection rooms. Afterwards, the samples have been inseminated in laboratory conditions for establishing the afterwards disinfecting effect on the farm. As a result, the microbiological investigation demonstrated that concentrations which were recommended by the producers and double concentrations of disinfectants don’t have satisfactory 100% of the anti-microbial and antifungal effect. For all disinfected places with the mentioned disinfectants colonies of microorganisms grew on nutrient media, especially bacterial forms as Streptococcus, Staphylococcus and microscopic fungal. Following comparisons, Ecocide S 3% and Na OH 3% had a higher efficiency than Aquadez 3%. The after application effect of Aquadez 3% established the presence of Salmonella, E. coli colonies grown on nutrient media as well as, Streptococcus and microscopic fungal.

Eco-Efficiency and Vulnerability of Agro-Ecosystems to Environmental Threats

Abstract

Eco-efficiency is based on environmental, social and economic principles, focusing not only on the use of fewer natural resources (raw materials) and energy but also on the cost-effective use of new technologies (eco-innovation) for the same volume of production and generation of low waste (efficient production). Agro-ecosystems globally, once with the development of the pesticide industry (plant protection products) and under the influence of aggressive marketing, have been based on the large-scale application of big amounts (perhaps too high) of pesticides. Many of the pesticides used in agriculture have a high persistence and degrade very slowly, which leads to the soil, water and even air pollution, with negative effects on plants, animals and, implicitly, humans. If these are used in short term and at low concentrations, pesticides can have beneficial effects (crop protection and their conservation and prevention of vector-borne disease) but in large quantities and applied over a long period of time can be toxic to humans and with a negative impact on the environment and ecosystems (degrading essential ecosystem services).

The Fertilizer Systems Efficiency in a Short-Term Crop Rotation in the Western Forest Steppe of Ukraine

Abstract

The results of energy estimation of a crop rotation link in the western part of Forest Steppe of Ukraine are presented. It is established that all proposed fertilizer systems are effective in terms of energy storage. It is proved that the use of mineral fertilizers in combination with organic fertilizers increases Kee indices by a factor of 1.2.
