RIULS

Repository of Iasi University of Life Sciences, ROMANIA

Welcome to RIULS!

The mission of the University’s institutional repository is to manage, preserve and disseminate, in open access, the academic and institutional output of the university’s academic community. It also aims to promote values and personalities belonging to Romanian agricultural science, by storing digitized versions of rare books and manuscripts from its collections.

The repository is part of the international movement known as open science, which promotes free access to scientific literature. This translates into maximized impact of the work carried out by researchers, contribution to improving access to knowledge, increased visibility of the institution through the works of its authors and improvement of its search engine ranking.

All documents deposited in the repository receive a unique and persistent identifier called a Handle, thus guaranteeing perpetual access to scientific output through permanent links.

RIULS Repository of Iași University of Life Sciences is indexed in Duraspace, OpenDOAR,CORE,Google Scholar,BASE (Bielefeld Academic Search Engine) and ROAR (Registry of Open Access Repositories), global Directories of Open Access Repositories.

Research regarding reproductive performance recorded for landrace x Yorkshire crossbreed sows used for bacon production
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Arsinte, R.P.; Al.-A. Casapu1; Nistor, Cătălin-Emilian; Nacu, Gherasim; Hoha, Gabriel; Păsărin, Benone
The aim of this study is to present the reproduction performance recorded at Landrace x Yorkshire cross bred sows exploited for bacon production in an elite unit in Denmark. We have investigated several reproductive parameters: fecundity (depending on season), index of using sows for reproduction, prolificacy, number of piglets farrowed dead and the survival percentage to weaning. The obtained results were: average fecundity is between 91.66 and 92.22%; the average index of use for reproduction is between 2.35 and 2.37; the average number of piglets farrowed alive is between 14.35 and 14.37. The results are a consequence of valuable genetic material, as well as of the technology applied in the unit. The results are situated within the data presented in the specialty literature for these parameters.

Genetic Diversity and Phylogenetic Analysis of the Endangered Transylvanian Pinzgau Cattle: A Key Resource for Biodiversity Conservation and the Sustainability of Livestock Production
(MDPI, 2024-12-06) Davidescu, Mădălina-Alexandra; Pânzaru, Claudia; Mădescu, Bianca-Maria; Radu-Rusu, Răzvan-Mihail; Doliș, Marius-Gheorghe; Simeanu, Cristina; Usturoi, Alexandru; Ciobanu, Andrei; Creangă, Șteofil
Animal biodiversity is essential for maintaining the functionality of local food systems and ensuring sustainable livelihoods. Starting in 2000, the Food and Agriculture Organization of the United Nations (F.A.O.) has drawn attention to the decline in cattle populations, including the Transylvanian Pinzgau breed from Romania. Renowned for its hardiness, adaptability, and enhanced resistance to diseases and climate change, the Transylvanian Pinzgau is regarded as an important genetic asset for advancing livestock production. As a result, tracking genetic diversity has become a key focus in breeding programs, particularly for small, endangered local populations that play a vital role in regional agro-ecological systems. This research paper sought to assess the genetic diversity of a group of 24 head of cattle from the Transylvania region by analyzing two mtDNA markers, cytochrome b and D-loop sequences, both widely recognized for their relevance and importance in the analysis of genetic diversity of cattle and phylogenetic studies. The findings, derived through statistical analysis of nucleotide sequences using specialized software, indicated that the analyzed cattle are part of the ancestral T haplogroup, with a direct lineage tracing back to Bos taurus. This information can aid in developing crossbreeding programs focused on conserving essential genetic resources, improving other cattle breeds, and protecting biodiversity.

Results regarding the study of reproductionindexes at brown breed cow population from Vrancea county
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Avram, P.; Nistor, Cătălin-Emilian; Gîlcă, Ioan
On a population of 1520 Brown cows, from 15 farms located in Vrancea County were evaluated the main reproductive indicators on the basis of data from official control in farms. Were evaluated the following indicators: rank of lactation, age at first calving (AFC), service period (SP), dry period (DP), calving interval (CI)and number of artificial inseminations for one gestation (IA). From analysis of mean values could be observed that average age at first calving was of approximately 33 month ranking between 29 and 35 month, the analysed population having precocity under the standard of Brown breed. Number of inseminations for one gestation was 2.09, at the farms level being recorded a poor management of frozen seminal material. Reproduction indicators had means values which prove that reproduction function was poor technically managed.

The role of antioxidants in boar semen preservation
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Cibotaru, Elena; Darie, G.; Pirlog, Alisa; Plesca, Doina
tract The aim of the research was to test the biologically active substance obtained by the Institute of Microbiology of the Scienсe Academy from Moldova. It was introduced in the basic medium as an additional component for boar semen dilution. The obtained experimental data showed that the introduction of 7% of the biologically active substance in the basic medium had positive results in the preservation of the semen material quality at 16-18° C. After 96 hours of conservation at 16-18° C the sperm motility of the spermatozoa was 54,3%.

Research on the influence of slow-growing technology on meat production at the chicken broiler
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Usturoi, Marius-Giorgi; Raţu, Roxana-Nicoleta; Usturoi, Alexandru; Gavrilescu Irimia, Carmen
In the last period, the poultry meat from other breeding systems than the industrial ones is increasingly being sought, which is why poultry farmers have used new hybrids and / or breeding technologies to meet this desire. For these reasons, we aimed to evaluate the quantitative production of meat in three hen hybrids (Ross-308, Hubbard and HB Color), reared according to the principles of slow growth and with slaughter at different ages (56, 63 and 81 days). After slaughtering, slaughter yields of 68.60-71.76% were obtained for the Ross-308 hybrid, 66.29 68.66% at Hubbard and 62.32-62.65% at HB Color. The cumulative weight of the two main components of the carcass (chest+thigs and drumstick) was 70.08-71.47% for the Ross-308 carcasses, higher by 1.60-3.23% compared to the situation from the Hubbard hybrid and by 6.92 9.21% than in HB Color. In contrast, the HB Color hybrid registered a high participation rate for wings (13.75-15.89%) and back (22.07-22.37%). In conclusion, it can be stated that the Hubbard hybrid provides good results in meat production (especially with slaughter at the age of 63 days) and which, in conjunction with other elements (productive performance, meat quality, etc.) recommends it for exploitation under slow growing conditions.
