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.

Comparison of reproductive performance in two old breed pigs breeds in Romania and Bulgaria
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Hoha, Gabriel; Palova, Nadezhda; Casapu, A. Al.; R.P. Arsinte, R. P.; Costăchescu, Elena; Păsărin, Benone
Reproduction characteristics of the two old breed pigs, Mangalita from Romania and East Balkan from Bulgaria were monitored over a three-year period (2015-2018). The reproduction characteristics: age and the weight at the first insemination; age at farrowing; duration of gestation; duration of lactation and prolificity from 20 sows of 2 litters were analyzed and compared. The results recorded for each parameters was: 530.42 vs 450.25 days for age at the first insemination; 112.52 vs. 90.45 kg for weight at the first insemination; 645.1 vs 563.7 days for age at farrowing; 114.7 vs 113.4 days for duration of pregnancy; 52.6 vs 59.2 days for duration of lactation; 5.62 vs 4.95 piglets at first birth; 6.28 vs 6.15 piglets at second birth. The obtained results confirm the data from the literature mentioning that the two breeds are tardiv. We also notice that the Mangalita breed is more tardiv than the East Balkan breed but has a higher weight at first insemination and a higher prolificity.

Contributions regarding improvement of productive performances at Kabir poultry breed
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Jitariuc, Ştefania-Elida; Raţu, Roxana-Nicoleta; Druc, Paula-Viorela; Roşca, C. D.; Usturoi, Marius-Giorgi
Poultry meat is considered an important food for human nourishment, due to its sensorial qualities and also to protein content with high nutritive values and with a reduced input in calories. Consumption of natural products started to be one of the main aims of population, fact for which also the Romanian farmers started to implement poultry rearing in traditional system in open air. In the current paper we aimed to study the growing performances of Kabir poultry breed, through analysis of morph-productive indicators. Regarding weight the first differences with statistical significance were observed in day 28 when mean values were 543.9±8.52 g for chickens from batch Lexp-1 and 620.0±12.39g for chickens from batch Lexp-2 (p˃0.001). Referring at fodder consumption, the highest values were highlighted during period in which was administrated GROWING type fodder (period 14 – 35 days) those ones being 1508.23 g/head at batch Lexp-1 and 1597.13 g/head at batch Lexp-2. The obtained data resulted from the current study highlighted the fact that Kabir poultry breed present a good outturn regarding growing, being also more resistant.

Milk fatty acid composition as a response to dietary n-3 fatty acids in Holstein dairy cows
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Vlaicu, P.A.; Panaite, Tatiana-Dumitra; Turcu, Raluca-Paula; Voicu, I.; Ropotă, Mariana; Olteanu, Margareta; Stănel, I.
Flax meal is known for its high content of alpha-linolenic acid, widely used as a source of fatty acid n-3 in animal feed. In this regard, a study on dairy cows was carried out to assess the influence of the use of flax meal on milk fatty acids. 15 dairy cows, Holstein breed (50 ± 23 days in lactation), with an average weight of 580 ± 37 kg, were divided into 3 experimental groups (C, E1, E2). Cows, were fed 2 times/day, and received a basic concentrate mix (corn, soybean meal, sunflower meal and wheat bran) and roughage (alfalfa hay and maize silo). Group C received the basic concentrate, while groups E1 and E2 received different formulations of concentrate by substituting sunflower meal (12%) for both groups (E1, E2). Besides, in the E2 group concentrate the wheat bran was substituted with barley rootlets (17.30%). Milk samples were collected in the morning and evening for a period of five consecutive days, on which the determinations of fatty acids were made using the chromatographic gas method. The use of flax meal in cows feeds resulted significant increase (P <0.05) in milk cows a of n-3 fatty acids at the end of the experiment for both groups fed flax meal, in the morning 0.53% and 0.54% in the evening (E1) 0.49% in the morning and 0.53% in the evening (E2) versus the C group (0.23%), representing a good source of omega 3. Such data indicated that the fatty acid addition was favourable to the fatty alpha-linolenic acid in milk.

Applying thermal treatments to chicken hatching eggs during storage and the effects on hatchability
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Bogdan, R.
Eggs incubation delay leads to lower hatching performance and weaker chick. The study was performed on ROSS 308 breeder eggs and followed the fertility and the impact of storage time on hatchability (A series), with decrease of hatchability with increase of storage time, from 80.77% (7 days) to 62.96% (21 days). The research in series A was based on results obtained from 936 eggs, spread over storage times (7, 14, 21 days) at 16°C, RH% 75%. Series B, followed the impact of thermal treatments applied to eggs during storage (7, 14, 21 days), on hatchability. Thermal treatment required egg exposure to 37.5°C for 120, 180 and 240 min. Three types of thermal treatments were applied, once for 7 days egg storage, 3 times for 14 days, 5 times for 21 days. Each thermal period x treatment combination was performed on 234 eggs, resulting a total of 6,318 eggs. Combinations for 7 days storage did not bring statistically significant improvements, combination of 2 x 180 min. is recommended for 14 days storage and for 21 days storage the combinations of 4 x 180 min. and 4 x 120 min.

The reproductive capacity of sows according to the fat layer thickness and genetic type of parental forms
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Rotaru, I.; Gaina, Efimia
The paper presents new results based on the study of reproductive capacities of hybrid sows according to the thickness of fat layer, parental forms genotype and the rank of farrowing. The growth speed of piglets that came out from using different paternal forms proved various values on a 21 days period. On sows that had a fat layer thickness up to 21 mm, the reproductive value was higher, regardless of farrowing rank, the prolificacy being stable and piglet’s growth index was superior to those who had fat thickness greater than 23 mm.
