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.

Comparative Analysis of Growth Performance, Morphological Development, and Physiological Condition in Three Romanian Cyprinus carpio Varieties and Koi: Implications for Aquaculture
(MDPI, 2024-11-12) Șerban, Dana-Andreea; Barbacariu, Cristian-Alin; Burducea, Marian; Ivancia, Mihaela; Creangă, Șteofil
This study investigates the influence of internal factors on growth dynamics in four Cyprinus carpio varieties, three Romanian strains (Frăsinet, Ineu, and Podu Iloaiei) and the Koi variety. Fish were measured for total length, maximum height, and weight at four ontogenic stages, namely 7 days post-hatch, 3 months (0+), 18 months old (1+), and 36 months (2+). Weight Gain (WG), Specific Growth Rate (SGR), Relative Growth Rate (RGR), Fulton’s condition factor, and the profile index were calculated and analyzed. Results revealed significant intervariety differences in growth performance and physiological condition across life stages. At the 2+ stage, Podu Iloaiei exhibited the highest WG (849.73 ± 4.09 g), while Koi showed the lowest (403.99 ± 14.21 g). Koi demonstrated a unique growth pattern, with the highest SGR (0.18 ± 0.00% day−1) and RGR (0.98 ± 0.05 g day−1) at the 2+ stage. Fulton’s condition factor varied markedly, with Frăsinet showing the highest value at 7 days post-hatch (149.57 ± 17.485) and Koi the lowest at the 1+ stage (0.63 ± 0.011). The profile index decreased with age in all varieties, with Podu Iloaiei showing the most dramatic change from 4.22 ± 0.149 at 7 days to 2.18 ± 0.004 at 2+. These findings highlight the complex interplay between genetic and developmental factors in carp varieties, offering new insights for tailored breeding programs and aquaculture practices.

The Influence of Season and Age on Specific Semen Traits and Reproductive Behavior in Carpatina Breed Bucks
(MDPI, 2024-11-20) Pascal, Constantin; Pânzaru, Claudia; Radu-Rusu, Răzvan-Mihail; Maciuc, Vasile; Florea, Alexandru Marian; Nechifor, Ionică
This study explores how age and seasonal changes impact semen characteristics and reproductive behavior in Carpatina breed bucks. Males were divided into three age groups: young (14–23 months; L14), adult (3–4 years; L34), and older (5–6 years; L56). Scrotal biometry was determined using a measuring tape, and testicular volume was evaluated by fully submerging the testes in a water-filled container and measuring the displaced water. Semen analysis was conducted on samples collected each season, with volume, color, and acidity being assessed. The evaluation of specific semen characteristics (motility, sperm concentration, normal spermatozoa) was conducted using a Computer-Assisted Semen Analysis (CASA) system, and testosterone levels were measured in blood samples collected at the start of each season. Behavior and sexual reflexes were evaluated based on mating desire and the bucks’ reaction to the presence of females. Key findings indicate that testicular volume varies significantly with both age and season, with the most pronounced differences between younger bucks and the older groups, especially during autumn. Semen quality parameters such as ejaculate volume, sperm concentration, and motility also showed seasonal fluctuations, with younger bucks having lower sperm concentrations. Testosterone levels were observed to increase with age, peaking in autumn. Behavioral observations revealed that younger bucks exhibited less intense sexual activity, although this improved during autumn. Additionally, a significant correlation was identified between body weight and testicular volume in adult bucks (R = 0.942, p-value = 0.016 for L34; R = 0.797, p-value = 0.022 for L56), suggesting that age plays a crucial role in reproductive potential. Our findings highlight that, while bucks are capable of year-round reproduction, autumn provides optimal conditions for semen quality and reproductive performance. This research has valuable implications for optimizing breeding programs, contributing to genetic advancement, and improving management strategies in goat farming, especially within temperate continental climates.

Equine Milk and Meat: Nutritious and Sustainable Alternatives for Global Food Security and Environmental Sustainability—A Review
(MDPI, 2024-12-13) Pânzaru, Claudia; Doliș, Marius-Gheorghe; Radu-Rusu, Răzvan-Mihail; Pascal, Constantin; Maciuc, Vasile; Davidescu, Mădălina-Alexandra
Global hunger and malnutrition continue to pose significant challenges, entailing innovative and environmentally responsible practices to improve food security. Equine products offer a valuable opportunity to diversify diets and combat nutritional deficiencies. Equine milk, rich in bioavailable nutrients, essential fatty acids, and hypoallergenic properties, serves as an excellent dietary supplement; this aspect could be applied particularly in regions where conventional dairy is inaccessible or unsuitable due to allergies, lactose intolerance, or other health conditions. Similarly, equine meat, known for its high-quality protein content, low fat content, and essential micronutrients like iron and zinc, provides an affordable and sustainable protein source for food-insecure populations. The ability of equines to thrive on marginal lands, coupled with their lower environmental impact compared to traditional livestock (such as ruminants), underscores their potential within sustainable agricultural systems. This review examines the role of equine products in addressing global hunger, highlighting their nutritional benefits, environmental advantages, and the necessity for further research to tackle challenges related to versatility, cultural acceptance, and policy integration.
