The research undertaken in order to determine the optimal dose and efficacy of the use of additives "Primix-Alfasorb" and "Primix-Bionorm-K", was conducted on broiler chickens of the meat hybrid COBB-500, in the laboratory of the Department of General Animal Husbandry of the State Agrarian University of Moldova, in the period from 11.18.2011 to 30.12.2011. To conduct the experiment on the basis of analogies, five groups of clinically healthy one day-old chickens of the Cobb 500 hybrid, 21 head each, were formed. The first group served as the control group, and received the basic diet; in the fodder for the second and the third groups, the experimental ones, the enterosorbent "Primix-Alfasorb" was added – 0.2 and 0.4 kg/t respectively; in the fodder for the fourth group the probiotic preparation "Primix-Bionorm-K” in quantities of 0.2 kg/t was added, and the fifth group received both probiotic and the adsorbent in quantities of 0.2 kg/t. In the trial the average live weight of the broiler chickens, which received the supplement "Primix-Alfasorb" in quantities of 0.2 and 0.4 kg per 1 t in EG1 and EG2, amounted to 1995.62 g and 2060.10 g respectively, with an average daily gain of 46.37 and 47.89 g, which was higher than in the control group by 2.20 and 5.55%. The supplementation of the fodder for the broiler chickens with the additive "Primix-Bionorm-K" at the level of 0.2 kg/t, increased the live weight of the broiler chickens in the EG3 by 10.40% (P . 0.01), the average daily gain by 10.62%, while the cost of the fodder per 1 kg of gain decreased by 7,94% compared with the control group. When both "Primix-Alfasorb" and "Primix-Bionorm-K" were added, the broiler chickens’ live weight in the EG4 in the scientific and economic trial, was of 1967.95 g, which was higher than the same index in the control group by 0.70 %. It was determined, that the optimal rate of enterosorbent "Primix-Alfasorb" input in the diets for broiler chickens was of 0.2 kg/t, and of the "Primix-Bionorm-K" of 0.2 kg/t.

Written by Eugenia SOVAREL, Paula POSAN

Generally, cardiovascular adaptations that occur in increase transport capacity and oxygen consumption in muscle during exercise in the horse are: increase of cardiac output (CO) by increasing heart rate (HR) and less systolic ejection volume (SV), redistribution of blood flow from inactive to the active territories, associated with increased venous return through muscle and respiratory pumps, increase the capacity of blood oxygen transporting with improved extraction and its retention in the muscles. A standard way of sport horses to respond to physical exercise is to increase cardiac output, possibly by increasing the HR and SV. The present paper analyzes the heart rate evolution and dynamic at 15 sport horses, during 3 periods of training. Assessment of heart rate was effectively executed indirectly (via stethoscope). Appreciated immediately after exercise heart rate increased in all 3 months of training proportional to speed, reaching a maximum of 81,86±1,14 cardiac movements / minute in the third month, at a speed of 550 m / minute and decreased at 10 minutes after effort, in all 3 months of training, reaching a minimum of 53,40±0,74 cardiac beats / minute in the third month at speed of 350 m / minute. Statistically the differences were insignificant in most cases were traced.

Written by Lumturi PAPA, Kristaq KUME, Fehmi XHEMO

The estimation of archaism index was used to study the local differentiation of seven Albanian local sheep populations. The estimation of archaism index was carried out using the morph-metric data of several features: whither height, tail length, ears length, horns and wattles presence, coat color, frontal-nasal profile. The cluster analyses was carried out using the Euclidian’s distances between populations in the plan of two first principal components. The cluster analyzes showed the existence of four distinguish sheep groups: first group -Ruda, Bardhoke, Baca, second group – Shkodrane, third group - Lara of Polisi, Syska of Mati, and fourth group -Recka. Based on the geographic distances between the regions where are bred the animals of these local sheep breeds and their geographic isolation can be concluded that the presence of local differentiation of Albanian local sheep populations is caused by the isolation in distance. These results show that in currant sheep population of Albania it is possible to find direct descendants of animals that have populated the Balkan regions in the form of three migratory successive waves. Currant results could be consider as preliminary one because of limited number of features included in the study and the complicity of this topic. They can serve as a bases for in-depth studies on local differentiation hypotheses of Albanian local sheep population.

Under certain conditions Aspergillus, Penicillium can produce and release secondary metabolites in feed type: Ochratoxin A (OTA). Ochratoxin A (OTA) has been shown to be highly nephrotoxic compounds, hepatotoxic and teratogenic. Ochratoxin affect animal health and can be found in animal products (meat, eggs, milk) presenting a potential risk to human health. Strategies to control OTA in feed and food requires early identification and removal of contaminated products in the food chain.Toxicity of mycotoxins depends on their source and dose, duration of exposure and composition. This paper aims to address this type OTA mycotoxins in feedingstuffs and possible risk you may present it on animals and man.

Table eggs represent one of the most valuable sources of proteins for the human diet. Therefore, their quality is a very important aspect for food safety and for public health. During a period of 6 months, samples of table eggs were collected as it follows: 20 samples of each category of exploitation systems for laying hens (organic, free-range, aviary and cage production). Duplicates of the following examinations were performed: Roche index (10 samples/week); total content of proteins, lipids, water and ash (two samples/week); CFU/eggshell as well as presence of Salmonella in the contents using three different selective agar media (8 samples/week). From the total number of 480 samples of each category, results showed the following: for the Roche index, organic eggs were evaluated at 10-11, for free-range and aviary ones, values reached 13 and for cage production systems, 8-9. The content of proteins (%) was higher for free-range eggs (12.48). The content in lipids showed high values for cage production eggs (11 %), but with close values for the other categories, reaching the minimum to 10.7 % in aviary eggs. As for the water content, the highest value was observed for free-range eggs, and for ash the lowest value was observed for cage production eggs, while the highest for organic eggs. Microbiological quality of table eggs revealed a significant bacterial load for the eggshell, of up to 5.06 log CFU/eggshell for free-range eggs, and 5.04 log CFU/eggshell for organic ones. Industrial systems revealed a lower bacterial load, of up to 4.83 log CFU/eggshell for aviary-obtained eggs and 4.67 log CFU/eggshell for cage production eggs. The number of samples in which Salmonella presence was detected was at it follows: 33 % of the organic table eggs samples, 28 % for the free-range table eggs, 25 % for the aviary-obtained table eggs and 14 % for the cage production ones. From the consumer point of view, eggs obtained in free-range and aviary systems could be the most appreciated ones. Chemically, results are very close from a category to the other, while the microbiological quality may differ, as a wide range of factors contribute to a certain bacterial load on the eggshell as well as for the presence of Salmonella.

Higher education plays an essential role in society, creating new knowledge, transferring it to students and fostering innovation. Mass access to higher education and the spectacular expansion of research are two concepts that become increasingly competitive and developed heavily in the recent years. If initially, the former enhanced the resources for the latter in the modern era of scientific discovery, the postmodernism brought equilibrium between the two concepts, in the production of knowledge time. Nowadays, there´s a strong consensus around the idea that there´s a new paradigm which forces people and organizations to reposition themselves. This new paradigm has evolved around concepts such as learning organizations and knowledge-based organizations, designations that emphasize teamwork, decentralization, organizational learning and knowledge. The proposed survey in this paper is the outcome of an European project whose main purpose was to help school leaders to improve ICT usage in teaching and learning, by better managing the information and knowledge available in their organizations. This expertize is now used at university level.

Amongst the many severely endangered species range the sturgeons. The diminishing stocks are considered to have been the result of several factors such as energetically hydro technical work, hydro technical work to improve conditions of navigation, excessive fishing, poaching and the increasing pollution. Typical migratory, the Black Sea sturgeons reproduce in rivers flowing here and hence the Danube. Deepening knowledge of migration and breeding conditions in this stage are a must. During the 2011 autumn migration there were monitored 50 copies of sturgeons from 4 species. Initial results showed that some marked specimens haven’t remained on the Lower Danube to winter but returned to the mouth of the sea, using the Old Danube route between km 197 and km 186.
