The study followed for a period of two years the evolution of African swine fever (ASF) in wild boars in Romania in 188 hunting funds from 41 counties. A total of 1471 positive boars were identified with African swine fever, of which 1217 were found dead and 254 were harvested positive by hunting. Several ways of disseminating the disease specific to the Romanian territory have been identified. A specific transboundary diseases crossing also was described. In parallel, the African swine fever dynamics was compared with the classical swine fever in wild boars. From the analysis of the data obtained, two models of the spread of the disease in the wild fauna were identified. Comparing the harvest of the two hunting seasons, a wave movement was observed from east to west of Romania, the number of cases remaining constant.

This paper aims to present the evolution of cattle numbers and production obtained in Neamț County during between 2010-2018. In carrying out this work, we have used statistical data provided by the Directorate for Agriculture and Rural Development, the County Animal Husbandry Office and the Association of Animal Breeders “Operator A.I.”. The analysis was carried out within two forms of property: population households and companies and private associations. The following were found: the population households registered a decrease in the number of cattle (ca. 15%) and in the average milk production (ca. 20%), while the companies and private associations had an increase in the cattle population by 44.4% and in the average milk production by 21%. With regard to meat production, the average weight for slaughter increased from 339 kg/head in 2010 to 451 kg/head in 2018, the share being 33.12%. The study found an improvement of the main indicators (cattle number and production) only in the holdings that have at least 40-50 heads compared to the holdings with 1-2 heads.

The increase of the agricultural surfaces cultivated with cereals that came to represent ~ 50% of the total areas destined to the agricultural activity, as well as the last years’ climatic changes mainly associated with the global heating which caused the increase of the temperature and humidity during the period of cereal harvest (in particular of wheat) required that monitoring of deoxynivalenol contamination would be a permanent concern in order to ensure the health of both, the human and animal population. In this study, the quantitative determination of deoxynivalenol contamination was pursued on a number of 584 samples, represented by unprocessed cereals, cereal flour, bread and bakery products, breakfast cereals and pasta. In the analysed samples, by the immuno-enzymatic technique and / or high performance chromatographic liquid, there were no registered values higher than the maximum level allowed for this parameter provided in Reg. EC no. 1881/2006 with the subsequent modifications and completions, but it was visible (even a doubling) of the deoxynivalenol contamination of the samples analysed in the year under test during which there were more abundant precipitation and increased temperatures in the wheat harvesting period. Following the study, it was found that the analysed samples correspond to the legislative requirements for the deoxynivalenol contaminant, and this parameter is permanently monitored in order to comply with the incident legislation.

This is another just part for an ample study regarding evolution of species from Cervidae family in Romania. The programme is developed in collaboration with Romanian Hunter’s Federation. The main purpose of this study is to reveal the reality, to find causes and to elaborate long term strategies in direction of biodiversity conservation, especially for wild game. In the last years the Romanian hunters indicate that the number of roe deer population decreasing, because of intensive agriculture and also because of high number of predators (bear, wolf and lynx population). We analyze the official data from national evaluation of sedentary game in Calarasi County. Hunting territories in this area are managed by National Forest Authority, county associations of hunters and other associations for conservation of biodiversity and management of hunting territories. We analyse cervidae real livestock between by counties, by sexes, and in comparison with optimal livestock (maximal number of individuals who can leave in a hunting area, without causing damage to the agricultural fields or in the forest). Considering the new agricultural technics and technologies it is relatively normal to find a numerical depreciation of wild game. But for cervidae populations, in analysed period in Calarasi County, we find a good and representative population. The differences between what can be saw in hunting territories and what is reported was analyzed. We can say that the evaluation, the official evaluation, is not perfect and we must work together to know exactly the livestocks and to develop a long term strategy for conservation of biodiversity.

It is known that the performances of the cows are influenced by the value of the mother and the value of the father for which it is important to know and group the performances so that the influence of the father can be highlighted. Therefore, the present study was conducted in order to identify the families of bulls, to study the performances of their daughters and also to determine their influence on these performances, analyzing the performances for milk production, percentage and quantity of fat and protein for cows that have completed maximum IV lactation. The biological material studied was grouped into 19 families with a total of 262 milk cows, the family with the highest milk production being given by the family with the Janther bull with an average production of 7975.80 ± 225.16 kg milk while the family with the smallest amount of milk was that of the bull Jecko Embriotransfer with an average production of 6474.20 ± 546.12 kg. The results obtained from this study indicate that the bull with the most influence on the descendants is the Janther bull, having the highest average yields on the quantity of milk, the quantity of fat in milk as well as on the quantity of proteins.

The aim of this study was the application of the latest FMEA (Failure Modes and Effects Analysis) method to improve food safety (for soup production) in food services. One of the major changes with the new FMEA method is that the Risk Priority Number (RPN) has been replaced by the Action Priority (AP) process. The working methodology consisted in the collection and processing of information based on practical experience provided by food industry and food services specialists, as well as those from the literature related to similar studies. Among the steps and activities required to apply the FMEA method is distinguished, as specificity, the calculation of AP depending on the severity (S) of consequences of manifestation of nonconformities to the consumer, on the probability of occurrence (O) of a potential hazard for food safety and on the probability of its detection (D). The AP was determined for each category of identified potential hazards (physical, chemical and biological) for all ingredients and for all stages of the technological flow. Through AP, a quantitative assessment can be made of the potential food safety problems in a system, and respectively a prioritization of implementation of preventive, corrective actions and the improve of prevention or detection controls. Based on AP, the identified potential nonconformities can be classified now in the Low priority category even if the old considered RPN value is higher than 100 (125, for the row material storage, at the level of physical hazards). On the other hand, at values lower than 100 of the RPN, the AP can be in the Medium priority category (96, for preparation of ingredients, at the level of chemical hazards), the value of S being the decisive element for classification of potential hazards and nonconformities.
