Inclusion of LFO in the diet did not affect milk yield or the protein and fat contents of raw and UHT milks; however, it improved the FA composition of the milk fat by increasing the concentrations of health-enhancing polyunsaturated FA and beneficially decreasing the n-6/n-3 FA ratio without adversely affecting the sensory properties of the final product (UHT milkTétel Korlátozottan hozzáférhető A brojlercsirke takarmánykeverékek valinkiegészítésének tapasztalataiTossenberger, János; Tóth, Tamás; Gyurcsó, Gábor; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető A tehéntej zsírsavösszetételének javítása takarmányozás útjánTóth, Tamás; Mwau Mwangi, Paul Joseph; Andrássyné Baksa, Gabriella; Bázár, György; PhD hallgató; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető A közeli infravörös spektroszkópia mint korrelatív gyorsvizsgálati módszer gyakorlati értékeléseTóth, Tamás; Bázár, György; Romvári, Róbert; egyetemi oktató, kutatóTétel Szabadon hozzáférhető Effect of ambient temperature and restricted feeding on the production of rabbit does and their kitsSzendrő, Zsolt; Papp, Zoltán; Kustos, Károly; egyetemi oktató, kutatóThirty-six lactating New Zealand White rabbit does were divided into 6 groups according to ambient temperature and feed intake. The does were kept at 20 °C during pregnancy and at kindling, then they were put into climatic chambers at temperatures of 5, 15, 23 or 30 °C. One part of the does were fed ad libitum (5A, 15A, 23A and 30A), two other groups were housed at 15 °C, but they received the same amount of pellet as the does' intake at 23 °C or 30 °C (15/23R and 15/30R). The litter sizes were equalized to seven. The weight of does, milk production, feed intake and water intake were recorded daily. Heat stress reduced milk yield (148, 152, 150 and 106 g/day), feed intake (287, 279, 260 and 179 g/day) and water intake (497, 512, 526 and 428 g/day), but increased the water/feed ratio (1.73, 1.84, 2.02 and 2.39) in the groups of 5A, 15A, 23A and 30A, respectively. Body weight of does decreased at 23 °C and 30 °C by 5.6% and 8.5%, respectively, compared to 15 °C. Comparing the groups of rabbits kept at 23 °C and 30 °C fed ad libitum (23A and 30A) and the data obtained for groups of 15/23R and 15/30R it was observed that the milk yield decreased by 8.0% and 2.5%, water intake increased by 8.6 and 13.3%, and the feed/water ratio was higher by 0.18 and 0.18, respectively. The effect of heat stress was less significant on kits than on does. It can be concluded that the high ambient temperature mainly affected the milk production through the reduction of feed intake.Tétel Korlátozottan hozzáférhető AZ IVÓVÍZ-TEMPERÁLÁS HATÁSÁNAK VIZSGÁLATA MELEGBEN TARTOTT NÖVENDÉKNYULAK TERMELÉSÉRETerhes, Katalin; Gerencsér, Zsolt; Szendrő, Zsolt; Nagy, István; Radnai, István; Kasza, Rozália; Matics, Zsolt; PhD hallgató; egyetemi oktató, kutatóTétel Szabadon hozzáférhető AZ ELTÉRŐ KÖRNYEZETI HŐMÉRSÉKLET HATÁSÁNAK VIZSGÁLATA ALACSONY ÉS MAGAS TESTZSÍRTARTALOMRA SZELEKTÁLT NÖVENDÉKNYULAKONTerhes, Katalin; Gerencsér, Zsolt; Nagy, István; Radnai, István; Kasza, Rozália; Dalle Zotte, Antonella; Cullere, M; Matics, Zsolt; egyetemi oktató, kutatóThe aim of the study was to investigate the effect of divergent selection for total body fat content on the production performance and carcass traits of growing rabbits at different ambient temperature. The experiment was conducted at Kaposvár University with Pannon Ka growing rabbits. Weaned rabbits (n= 60 Lean and 60 Fat rabbits/room) were housed in two identical rooms where the temperature was controlled with air conditioner. In the control room the average ambient temperature was 20°C and in the other room it was 28°C. The rabbits were born in these rooms, and were housed from weaning (5 wk) to slaughtering (13 wk) in wire-mesh cages (2 rabbits/cage) and fed ad libitum with commercial pellet. Body weight and feed consumption was measured fortnightly and the individual weight gain and feed conversion ratio were calculated. At the end of the experiment rabbits were slaughtered. The temperature significantly influenced the production performance and carcass traits. On higher temperature feed intake, weight gain and body weight decreased but the feed conversion ratio improved. The Lean rabbits were heavier and their chilled carcass was greater than Fat rabbits on higher temperature. On control temperature Fat rabbits consumed more feed and their feed conversion ratio deteriorated. The perirenal and scapular fat were lower on higher temperature in both genotype, but Fat rabbits had significantly more fat than Lean rabbits. The higher temperature had negative effect on the production but Lean rabbits had better results in some traits than Fat rabbits.Tétel Korlátozottan hozzáférhető A születési súly szerepe a nyulaknál (1. rész)Szendrő, Zsolt; Szendrő, Katalin; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető Eltérő környezeti hőmérséklet hatásának vizsgálata alacsony ill. magas testzsírtartalomra szelektált anyanyulakonTerhes, Katalin; Kasza, Rozália; Donkó, Tamás; Szendrő, Zsolt; Radnai, István; Gerencsér, Zsolt; Hatvani, Ferenc; Matics, Zsolt; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető AZ IVÓVÍZ-TEMPERÁLÁS HATÁSÁNAK VIZSGÁLATA MELEGBEN TARTOTT ANYANYULAK TERMELÉSÉRETerhes, Katalin; Gerencsér, Zsolt; Szendrő, Zsolt; Nagy, István; Radnai, István; Kasza, Rozália; Matics, Zsolt; PhD hallgató; egyetemi oktató, kutatóTétel Szabadon hozzáférhető A review of biochemical and nutritional properties of Stevia rebaudiana Bertoni (Natural Sweetener)Ismail, Tariq; Ponya, Zsolt; PhD hallgató; egyetemi oktató, kutatóStevia as a bio-sweetener having no calories, and proved as not toxic for Human health, it is used in large quantity in industries and daily consumptions. About 300 times sweeter than sucrose. Stevia extracts, beside medicinal properties, contain a high level of sweetening compounds, known as steviol glycosides. This review is an effort to explore the possibilities of using stevia in commercial products, as well as to know the nutritional and biochemical contents present in stevia leaves, and use of stevia leaves as a basic constituent for many products for consumption.Tétel Korlátozottan hozzáférhető A születési súly szerepe a nyulaknál (2. rész)Szendrő, Zsolt; Szendrő, Katalin; egyetemi oktató, kutatóTétel Szabadon hozzáférhető Efficacy of H-Traps is Affected báy Exposure to SunshineOtártics, Máté Zsolt; Altbäcker, Vilmos; Solymosi, Kristóf; Mátics, Róbert; Romvári, Róbert; Farkas, Sándor; egyetemi oktató, kutatóated the impact of the factors affecting the efficacy of H-traps. Catching data of 15 H-traps were analyzed. The traps were deployed at an outdoor equestrian paddock (Sántos, Somogy county) from May to July 2018. In twelve weeks, the traps collected 10,556 horsefly specimens, dominated by Tabanus autumnalis and Haematopota italica. In the first experiment we found that the distribution of caught individuals was inhomogeneous among the samples. According to the amount of caught individuals, trap efficacy showed spatial and temporal inhomogeneity. In the second experiment, after the rearrangement of traps, we found that traps placed in open, sunny places in the centerline area caught significantly more horseflies than those in shady border regions. It can be concluded that the positioning of H-traps in sunny areas significantly enhances their tabanid-catching efficacy.Tétel Szabadon hozzáférhető The influence of the North Atlantic Oscillation on the potential distribution areas of Bursaphelencus xylophilus in Europe based on climatological reanalysis dataSomfalvi-Tóth, Katalin; Keszthelyi, Sándor; egyetemi oktató, kutatóPine wood nematode (Bursaphelenchus xylophilus) (Aphelenchida: Parasitaphelencidae) is one of the most harmful agents in coniferous forests. The most important vectors of pine wood nematode are considered to be some Monochamus species (Col.: Cerambycidae), which had been forest insects with secondary importance before the appearance of B. xy- lophilus. However, the continuous spreading of the nematode has changed this status and necessitated detailed biological and climatological investigation of the main European vec- tor, Monochamus galloprovincialis. The potential distribution area of M. galloprovincialis involves those areas where the risk of the appearance of pine wood nematode B. xylophilus is significant. The main objective of our analysis was to obtain information about the influencing effects of North Atlantic Oscillation (NAO) on the potential European range of B. xylophilus and its vector species M. galloprovincialis based on the connection between the mean temperature of July in Europe, the distribution of day-degrees of the vector and the NAO index. Our assessment was based on fundamental biological constants of the nematode and the cerambycid pest as well as the ECMWF ERA5 Global Atmospheric Reanalysis dataset. Our hypothesis was built on the fact that the monthly mean temperature had to exceed 20°C in the interest of an efficient expansion of the nematode. In addition, the threshold temperature of the vector involved in the calculations was 12.17°C, while the accumulated day-degree (DD) had to exceed the annual and biennial 370.57°DD for univoltine and semivoltine development, respectively. Our finding that a connection could be found between a mean temperature in July above 20°C and NAO as well as between the accumulated day-degrees and NAO can be the basis for further investigations for a reliable method to forecast the expansion of pine wood nematode and its vector species in a given year.Tétel Szabadon hozzáférhető Oxidative stress level and dehydrin gene expression pattern differentiate two contrasting cucumber F1 hybrids under high fertigation treatmentOszlányi, Réka; Mirmazloum, Iman; Pónya, Zsolt; Szegő, Anita; Bat-Erdene, Oyuntogtokh; Papp, István; PhD hallgató; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető Tojóhibridek értékmérőinek változása nyújtott termelési időszakban, a tartás módjától függőenSütő, Zoltán; Budai, Z; Almási, A; Milisits, Gábor; Ujváriné, J; Garamvölgyi, E; Horn, Péter; PhD hallgató; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető Anyanyulak elhullása és selejtezéseSzendrő, Zsolt; Barna, Judit; egyetemi oktató, kutatóTétel Korlátozottan hozzáférhető Challenges and adaptive strategies in pig breeding from the aspect of heat stress and heat toleranceNagy, István; Kövér, György; Gerencsér, Zsolt; Szász, Gabriella; egyetemi oktató, kutatóAuthors summarized the results of the last three decades’ relevant literature examining the temperature effects on the various growth, reproductive and carcass traits in pigs. The ideal period of temperature measurement and the different methodologies characterizing temperature effects were summarized. The aspects of genotype environment interaction for the measured traits under hot and temperate conditions were also presented. Finally the possibilities of direct genetic selection for heat tolerance and its possible selection criteria traits were also discussed.Tétel Korlátozottan hozzáférhető Rovarliszt a baromfitakarmányban II. részSzendrő, Katalin; Gyenis, József; egyetemi oktató, kutató
