Abstract The artificial insemination (AI) technique is an essential tool in goat breeding programs, since it increases the efficiency of sire genetic evaluation and the extension of genetic improvements; at the same time, it enables control of parturition dates with a view to meeting market demands. The objective of this study was to determine the fecundity rate according to the mode of semen preservation before artificial insemination. The percentage of kidding was influenced by the duration of storage: 3 h = 88%; 14 h =821%.

Abstract For livestock holdings, the breeding sector is the most important and the level of breeding technical indicators is the path to profit or loss. It can be said that in animal husbandry, this is the sector with the highest degree of technicality and that is why there were made efforts in research to create modern techniques that allow the man to control all these phenomena and the level of indicators to not depend only on the capabilities of the bull, boar, ram and rooster, etc. The aim of this paper is to provide a view upon the use of breeding biotechnologies in Romanian livestock. Based on the data of National Agency for Improvement and Reproduction in Animal Husbandry were analyzed the dynamics of artificial insemination, in species of livestock contained in Official Control of Production (COP). The dynamics of embryo transfer in cattle, in Romania, in the period 2000-2012 is based on data reported by the Romanian Association of Embryo Transfer (A.R.E.T.) to the European Association of Embryo Transfer (A.E.T.E.). Although until 1990 agricultural research and the system of state enterprises favored the application of these biotechnologies, after 1990, the highly divided property in agriculture and the lack of organization of farmers in associative forms resulted in the restricted use of these modern techniques. Regarding the use A.I., in the analyzed period, the total number of A.I. decreased by 55%, due to the changes that have occurred since 1990, with the restructuring that occurred in livestock (reducing the number of large farms and the continue decline of the number of females) and in the national network of breeding and selection of animals. In Romania, due to high costs, embryo transfer is not a method currently used and accessible to ordinary farmers, being used mostly to obtain the bulls used in artificial insemination network or the cows as steers mothers.

Abstract People are increasingly concerned in the quality of food they consume in order to increase their health and live a life devoid of illnesses. As proven, food in a huge contributor to human body as it is fuel that makes the human machine function appropriately. Nowadays, there are a lot of chemicals used in raising crops, vegetables, fruits and there is a fierce chasing for food devoid of chemicals. The present article focuses on the impact of the food we ingest has on the health and wellbeing of people.

Abstract In the context of rising food requirements regarding quality and food safety, it is necessary to obtain high quality of animal productions. In this respect, one of the most important factors which participate in the formation of animal production quality is the quality of feed administered in animal feeding. For this reason, in the present workpaper we intend to study applied technology to improve the quality of red clover for obtaining high forage and quality production in a sustainable agricultural system. The objectives of this workpaper is to develop solutions for integrating culture of red clover in a sustainable agriculture system, respectively, exploiting of local resources fertilizer, reducing inputs in culture system of fodder in Plain Targoviste, exploiting the potential of improve soil fertility by growing the fodder.

Abstract In this work were evaluated the correlations between different forms of carbon dioxide naturally existing in fountain waters and the pH. Water samples were taken from five wells equally placed on the surface of Picior de Munte area in Dambovita county and were collected in each of the four seasons (spring, summer, autumn and winter). They were evaluated two forms of carbon dioxide (one was the aggressive CO2 and the other was that sequestered in bicarbonates molecules). It was used titration method based on the principle of conversion calcium carbonate in to bicarbonate form. The results showed that both forms of carbon dioxide naturally founding in underground water are related to the pH, and also are varying from a season to the other. For example, both forms of carbon dioxide significantly were influenced by pH in summer and in spring also, the proof being the values of regression index wich was 0.583 and respectively 0.679. That is showing a moderate to strong influence depending on the season. In autumn and winter, the influence of pH on carbon forms analyzed was lowest one, the regression index value being 0.309 and 0.260. Also, the influence of carbon dioxide forms on the water pH level varied also from a season to another. Thus, carbon dioxide from bicarbonates strongly influenced the water pH in spring and autumn seasons, so the regression index value was 0.783 and respectively 0.548. But in winter and summer the influence ranged from moderate to weak (R2 = 0.413 and 0.316). The aggressive carbon dioxide significantly influenced water pH in the summer season, the fact is proved by the value of regression index which was high, 0.857. In the others seasons the influence of aggressive carbon dioxide was insignificant.
在这项工作中，评估了喷泉水中自然存在的不同形式的二氧化碳与ph之间的相关性。水样取自Dambovita县Picior de Munte地区表面均匀放置的五个井，并在四季(春、夏、秋、冬)中采集。他们评估了两种形式的二氧化碳(一种是侵略性的二氧化碳，另一种是封存在碳酸氢盐分子中的二氧化碳)。采用了基于碳酸钙转化为碳酸氢盐形式原理的滴定法。结果表明，在地下水中自然形成的两种形式的二氧化碳都与pH值有关，并且随季节而变化。例如，在夏季和春季，两种形式的二氧化碳都受到pH的显著影响，回归指数分别为0.583和0.679。根据季节的不同，这种影响从中等到强烈。在秋季和冬季，pH对碳形态的影响最小，回归指数值分别为0.309和0.260。此外，二氧化碳形态对水pH值的影响也因季节而异。由此可见，春季和秋季碳酸氢盐二氧化碳对水体pH的影响较大，回归指数值分别为0.783和0.548。而冬季和夏季的影响从中度到轻度(R2 = 0.413和0.316)。夏季侵蚀性二氧化碳对水体pH有显著影响，回归指数较高，为0.857。在其他季节，侵略性二氧化碳的影响微不足道。

Abstract Rye is an important cereal because it is a very good alternative for wheat in harsh conditions of culture (less productive agricultural land, dry area). This cereal could be used as row material in food industry processing and for animal feed. From this point of view, this project was aimed to identifying the culture area of rye in Southern Hilly Area of Romania and assess yield in terms of quality. The activity was held during 4 years of study, period which we found that the rye was grown only in some years of study and not all counties of the region. Considering the potential and importance of this cereal, required that making some studies of the crop rye quality in different regions of Romania.

Abstract The production of milk, the quantity of fat respectively constitute the main criterion of assessment of dairy cows in the mountain area and downhill. The average performance in the succession of eight lactations per total lactation is 3420.67 kg, and per normal lactation is 3209.20 kg milk. The limits vary between 1506 kg of milk and 8835 kg milk recorded for lactation and 1506 kg of milk and 7322 kg milk for normal lactation. The study of statistical parameters of index of the total duration of lactation allows us to affirm that the cows from the herd studied have the genetic potential to increase lactation beyond the limits of normal lactation of 305 per days. Milk production per day is higher with + 0.45 kg per total lactation than normal lactation. Extension of lactation and breast resting shortening represents loss of milk production in both current lactation and the next lactation. To estimate the effect of localities was used the analysis of variance within samples. Raw data tables have been processed to create tables of variances between herds of the 6 localities and within the herd in each locality. The influence of the locality on the milk production is null. The output production of milk cows has as enablers: daily output and duration of lactation on her. The raise of the productive cows milk level in the mountain area and hence income breeders is achievable through the integration and expansion of biotechnology.

Abstract In the southwestern part of Romania, in the Oraviţa Depression, which is included in the Banat historical region, there is a low altitude air circulation in the cold season. Under certain conditions of atmospheric pressure, it generates a catabatic wind (Coşava), with strong increases in speed at blast. The wind speed, which often exceeds 10 m / s, causes sometimes-massive damage to property.
