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.

A.; Lele, S. F.; Morariu, F.; Sîrbu, B. A.-M.; Sîrbu, C. B.; Peț, I. B.; Popa, N. F.; Peț, I.Ambrosia artemisiifolia L. is an invasive weed species with major negative agronomic, economic and health impacts, reducing crop yield through intense competition for resources and producing highly allergenic pollen with harmful effects on human health. Alfalfa (Medicago sativa L.) is most vulnerable in the first developmental periods, when biomass accumulation is slow and seedlings cannot effectively compete for resources, leading to significant loss in stand density and productivity. The presence of A. artemisiifolia in M. sativa forage pastures is problematic, as it has no nutritional value and may even be harmful to livestock. The aim of this study is to evaluate the efficacy and selectivity of halauxifen-methyl and imazamox, applied individually and in combination with biostimulants, in a M. sativa forage field infested with A. artemisiifolia population. While halauxifen methyl is not currently registered for use on this crop and no official data exists regarding its application with biostimulants, imazamox is approved and is the comparative standard for this trial. This study seeks to highlight the potential of halauxifen-methyl as a treatment for alfalfa, as well as the role of biostimulants in reducing herbicide-induced stress and enhancing M. sativa tolerance to herbicides during its early developmental stages. The mixture of halauxifen-methyl and biostimulants provided the highest control levels, ranging from 70 to 95% during the trial period. Control of A. artemisiifolia reached 90 - 95% at 28 days after application, compared to 85- 90% without a biostimulant. Alfalfa injury symptoms in the variant treated with halauxifen-methyl and biostimulants were transient, consisting mainly of slight to moderate chlorosis, with the plants fully recovering by the third assessment, at 42 days after the application. This study confirms that the post-emergence application of halauxifen-methyl at 1 L/ha combined with biostimulants, provided excellent control of A. artemisiifolia. These results demonstrate that the combination of herbicides and biostimulants offer a promising option for an efficient and sustainable chemical control.listelement.badge.dso-type Item , listelement.badge.access-status Open Access , Territorial organization and reproductive performance of public mount stallions in north-eastern Romania(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Prisacaru, M. C.The public mounting system plays a key role in horse breeding programs by ensuring controlled reproduction and genetic improvement at regional level. This study aimed to analyze the territorial distribution and reproductive performance of public mount stallions in North-Eastern Romania, based on official breeding records collected over multiple years. Data were analyzed for six counties (Neamț, Iași, Bacău, Botoșani, Suceava and Vaslui), considering breed structure and main reproductive indicators, including the number of mares covered, gestation rate, fertility and natality. The results highlight marked differences among counties in both stallion distribution and reproductive efficiency. In several counties, Romanian Semigreu stallions represented the dominant breed, while other improved breeds contributed locally to breeding activity. Overall reproductive performance was variable, with higher efficiency recorded in counties with a more stable stallion structure and higher mare utilization rates. The findings underline the importance of territorial management and breed allocation in optimizing the outcomes of public mounting systems.listelement.badge.dso-type Item , listelement.badge.access-status Open Access , Role of rustic pig breeding in rural development and evaluation of the morphological characteristics and productivity of certain indigenous breeds(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Kui, D.; Creangă, ȘteofilBelonging to the natural environment for the sustainable use of animal resources in the environmental conditions of our country, but also in the context of climate change, requires prospects for the growth of these breeds in the current picture of consumer demand for high-quality meat and of breeders for disease resistance and reasonable maintenance costs. The present research aims to highlight the genetic diversity and morpho-productive characteristics of some native pig breeds, their importance in the country's sustainable economy, and their reintroduction into traditional breeding systems. The first part of this presentation will describe the primitive pig breeds of Asia and Europe, their origin, and their contribution to the formation of new breeds. Classification and description of Romanian breeds and populations by geographical area, presentation of the origin of each breed and population, growth prospects, and their role in Romania's sustainable economy. The role of genetic conservation and its usefulness in improving, in particular, organic resistance and the organoleptic and preservation qualities of meat for the production of traditional Romanian food products. The estimation of production costs, taking into account the hardiness of native pig breeds (use of pastures, pigsties, food scraps). The research is based on morphological analysis in the field of local pig populations, followed by the collection of biological samples (blood) to establish genetic identity and diversity using molecular genetics laboratory methods (PCR – polymerase chain reaction) to demonstrate the spatial and temporal sustainability of individuals.listelement.badge.dso-type Item , listelement.badge.access-status Open Access , Research on using the PG 600 in gilts(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2026) Nacu, Gherasim; Ciornei, Ștefan; Donosă, Raluca-Elena; Ivancia, Mihaela; Nechifor, F.Hormonotherapy is frequently used in swine to induce fertile oestrus in both sows and gilts. The research was conducted over a year on a total of 953 Camborough sows, at least 210 days old at the beginning of the observations, divided into two groups: a control group (642 sows) and an experimental group (311 sows). In the control group were monitored the dynamics of oestrus for 27 days after transfer to the pre-breeding barn, the fertility, and the prolificacy. The appearance of oestrus was analysed in the experimental group for 21 days after transfer. 106 gilts that did not show oestrus during this period were treated with a 5 ml dose of PG 600, administered intramuscularly behind the ear. The oestrus dynamic was analysed for 6 days, along with fertility and prolificacy. After gonadotropin administration, 75.47% of the swine came into heat, compared to 38.73% in the control group. The best response to treatment was in spring (81.81%) and winter (82.60%), and the largest difference between the groups was recorded in summer (45.62%). The average fecundity rate of the gilts in the experimental group was 82.50%, being 1.22% lower compared to those in the control group. The average litter size was 10.32±0.11 piglets/litter in the control group and larger in the experimental group (10.83±0.12 piglets/litter). The results obtained demonstrated the effectiveness of gonadotropin treatment for optimising reproduction in gilts, particularly in those with seasonal anoestrus, oestrus synchronisation, and increased prolificacy.
