Researches Regarding the Reproduction Outline and Indices in a Beef Herd in the South of Romania

AbstractWorldwide, having as aim the more and more cost effective animal rearing, specialized breeds are used by practising and experimenting modern methods of animal breeding and reproduction. Planning the adequate reproduction activity to each farm purpose in view leads to some high technological indices.The aim of the present paper is the one of assessing the best methods of reproduction planning activity in a beef herd. There were analyzed the reproduction indices in a Charolais livestock, allotted to three categories of females: primiparous 36 females, 29 secundiparous females and 15 multiparous, a total of eighty-two reproduction stock. The study was conducted during three years and the reproduction indices were the following: length of pregnancy, service-period, calving interval, fertility rate, and sex ratio of the offspring. The animals come from import, from a total livestock nucleus of 21 heifers and a bull, the farm livestock increasing gradually to 96 heads. The females were used maximum five calving, and then culled. The age of females’ introduction to reproduction is 22-24 months, the first calving being achieved at 2,5 years, maximum 3 years. There were used the grouped calving system and individual calving system along the year.Following the three years study, even the reproduction indices did not differ significantly, by the grouped calving system obtained in early spring with the aid of synchronized heats, the early calves used better the grazing season offering increasing amounts of meat with less costs

Study Regarding Age-Related Morphometric Features of Buffalo Sperm

AbstractSemen production quality from reproduction males depends upon different factors such as:age, breed, collection method, environmental conditions. The present research was conducted to establish the influence of age upon the quantitative and qualitative indices of the native buffalo semen. There were analyzed 20 native buffalo males, from different age categories. At every semen collecting there were recorded the following morphologic and morphometric sperm indices: sperm volume, sperm concentration (x 106spz/ml), total number of sperm cells/ejaculate(x109), head length, head width, tail length, head area and shape factor.The influence of the age was made along two years, studying the dynamics of the sperm indices through the computer image analysis. Descripted statistics were performed on the recorded data to determine normality. Statistical analysis was performed as per standard statistical methods.The results revealed the fact that the best performances were recorded in bulls older than three years old. The study clearly demonstrates that there is a variation in reproductive parameters in the bovine bulls, which could be studied at the molecular level to unveil any genomic markers associated with low fertility and/or infertility. The males may be utilized to obtain semen by subjecting the young ones to training at an early age, thereby decreasing the initial age of semen donation

ROMANIAN RED BIOTECHNOLOGY - BLENDING TRADITION WITH STATE OF THE ART IN THE EUROPEAN AND INTERNATIONAL FRAMEWORK

The biotechnology field has grown rapidly in recent years. Much attention is given to the potential of the biotechnology industry, from drugs and medical devices to environmental products which have the potential to generate tremendous opportunities for society, by improving the quality of health care and producing a cleaner environment. Redbiotechnology, or medical biotechnology, is one of the branches of the biotechnology and utilizes the organism to improve health, both in the pharmaceutical and medical sectors, mainly bringing all the biotechnology applications to medicine. Romanian potential was recognized by important biotech companies as an attractive destination for biotechnology research development. Currently running large programs for research, development, and innovation, regulated within a national implementation strategy, and with an attractive higher education offer, Romania is contributing to biotech advances and has great potential for development of biological pharmaceutical products. It also represents a valuable and promising partner for future international collaborations as biotechnology continues to evolve and will remain a major field of innovation and development in many areas of the world

Current state and prospects of biotechnology in Central and Eastern European countries. Part II: new and preaccession EU countries(CRO, RO, B&H, SRB)

Innovation holds the potential for economic prosperity. Biotechnology (BT) has proved to be a viable vehicle for the development and utilization of technologies, which has brought not only advances to society, but also career opportunities to nation-states that have enabling conditions. In this review, we assess the current state of BT-related activities within selected new and preaccession EU countries (NPA) of CEE region namely Croatia, Romania, Bosnia and Herzegovina and Serbia, examining educational programs, research activity, enterprises, and the financing systems. The field of BT covers a broad area of activities, including medical, food and agriculture, aquaculture or marine, environmental, biofuels, bioinformatics, and many others. Under the European Commission (EC), member-states are to set their Research and Innovation Strategies for Smart Specialization (RIS3), to identify priorities or strengths in order to develop knowledge intensive economies. As the four countries highlighted in this review are in the early stages of implementing RIS3 or have not yet fully formulated, it presents an opportunity to learn from the successes and failures of those that have already received major structural funds from the EC. A critical point will be the ability of the public and private sectors' actors to align, in the implementation of RIS3 as new investment instruments emerge, and to concentrate efforts on a few select target goals, rather than distribute funding widely without respect to a long-term vision
