Our interest focused on the feed preference (i.e. if the mice choose the type of feed closest to their natural food). The proximate composition of the two granulated feeds offered to mice differed minimally; the crude fat and crude fibre content of the natural feed mixture was higher, and only this feed contained insect protein. Based on the obtained results, both wild mice species approached the natural feed mixture more frequently than the two other granulated feeds. The same tendency was observed for feed consumption where the animals mostly consumed the natural feed mixture. During the 5-day long study, the consumption of the natural feed mixture increased continuously, while the consumption of the granulated laboratory feed decreased significantly. The average feed consumption was also influenced by room temperature. Our studies can help to develop the optimized indoor keeping and breeding of small domesticated mammals.","PeriodicalId":403816,"journal":{"name":"Acta Agraria Kaposváriensis","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128242158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By Knott’s test and molecular confirmation of infected status, 11.7% prevalence could be detected in 95 domestic dogs. In risk analysis, urban residence and female sex proved to carry high risk of infection. On the other hand, age, breed, hair length showed no impact on infection status.

Three groups of weaned rabbits (5 weeks of age, n=243)) were established: AL=control group: ad libitum feeding during the whole fattening period (n=81), RF65 group: 65% of the feed consumption of AL during the first two weeks after weaning, 80% in the third, 100% in the fourth week and ad libitum afterward (n=81), RF70 group: 70% in the first two weeks, 80% in the third, 100% in the fourth week and ad libitum till slaughtering (n=81). Feed consumption was in line with the planned level during the feed restriction period. After finishing the restriction at 100%, the feed consumption increased rapidly, and it was higher between 9 and 11 weeks of age than that of the AL group (P<0.001). Daily weight gain of restricted groups was lower between 5 and 7 weeks of age (47.7 vs. 28.9 and 25.2 g/day in AL, RF70, and RF65, respectively, P<0.001). The differences in body weights were highest at seven weeks of age, and later the differences decreased (body weight at 11 weeks, AL: 2710 g, RF65: 2637 g, RF70: 2655 g, P <0.05). In the first week, the feed conversion rate was better in the AL group, while between 7 and 10 weeks of age, it was better in the restricted groups (P<0.001). Significant differences were found in mortality but independent of treatment. The feed restriction had a slight effect on carcass traits. The weight of the fore part of the carcass was higher in the AL group (P=0.053), while the liver was heavier in the restricted rabbits (84.2 vs. 80.1 g, P=0.388). The perirenal fat content was the lowest in RF65 rabbits (16.9 g) and the highest in the AL group (21.6 g, P<0.05). A stricter and then milder feed restriction after weaning and ad libitum feeding in the final fattening stages could be preferred.","PeriodicalId":403816,"journal":{"name":"Acta Agraria Kaposváriensis","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123828855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tenyészcéljuk megváltozott, a katonai hasznosítást a hobbi- és sportcélú használat váltotta fel, ami nyomot hagyott az állományokon. Az elmúlt évtizedekben a populációgenetika, különösen a pedigréelemzés, felértékelődött. A származási adatokat amennyiben lehetett egészen az alapítókig visszavezettük, így az elkészült adatbázisunk több mint 47.000 egyed adatait tartalmazta.

Cytological appearance of inflammation in mammary gland depends on the origin and the time-course of the inflammatory response. According to predominant cell type there can be suppurative, pyogranulomatous, granulomatous and lymphocytic inflammation. Prototheca spp. as facultative pathogen creates chronic inflammation in mammary gland with high SCC and reduced milk production. The aim of our study was to elaborate a practical and accurate laboratory procedure to enhance the precision of milk somatic cell differentiation, and to provide quick and easy-to-perform detection for the presence of infectious algae in mastitis cases. In 95 quarter samples SCC was determined by California Mastitis Test, cellular density estimation and somatic cell differentiation were carried out by microscopically evaluation, while presence of Prothoteca spp. was investigated with the help of specific culture medium (PIM agar). According to CMT results, SCC values showed 67.3% prevalence of mastitis, from which 6.3% was clinical and 93.7% subclinical. Comparing CMT results and estimated cellularity values indicated tight correlation. In CMT negative quarters 60% of somatic cells were neutrophil granulocytes, while in CMT positive but Prototheca spp. negative cases these cells were present in 74%. Interestingly in Prototheca spp. positive samples only 60.25% of cells were neutrophil granulocytes, while macrophages and lymphocytes were present in 17% and 18.3%, respectively. Moreover, remarkable cytological pattern was notified in some samples that were positive for Prototheca spp., and statistical analysis showed tight correlation between infectious algae and the ratio of macrophages (p=0.005). In conclusion laboratory techniques applied in our study seems to be helpful supplementary methods to reveal pathological background of mastitis as well as to monitor the progression of inflammatory reactions.","PeriodicalId":403816,"journal":{"name":"Acta Agraria Kaposváriensis","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131582678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The examined trait was the duration time until the animals approached the experimenter’s hand. The available time was fixed in 300 seconds. There were monitored 80 mice belonging to two different species of the Mus genus in equal proportion. Besides, male and female and young and adult animals have also represented the evaluated groups in equal proportions. The data of the examined trait was analyzed with Generalized Linear Models, Kaplan-Meier survival curves, and with Cox Proportional hazard model. The applied statistical procedure provided completely discordant results. According to the GLM results none of the examined factors (species, sex, and age) had significant effects on the examined variable. On the contrary, all factors proved to be significant using a procedure based on the survival analysis. Kaplan-Meier survival curves indicated a higher proportion of individuals successfully approaching the experimenter’s hand in all of the compared groups representing different species sexes and ages, respectively. The estimated Cox regression coefficients were significant indicating the significant effects of the species, sex, and age on the investigated trait. Based on the estimated Hazard ratios the probability that in the next time unit a successful approach of the experimenter’s hand would occur is three times more likely for one species than the other, twice as much for males and the juveniles than for the females and for the adults. Based on the present study it could be concluded that the successful approach of the experimenter’s hand by the mice is clearly “time to event data” thus it is suitable to be analyzed with survival analysis procedures. It could be concluded that applying conventional GLM was not adequate because due to the lack of the successful approach and approach times the censored data should not be used and thus the sample size would largely be reduced.","PeriodicalId":403816,"journal":{"name":"Acta Agraria Kaposváriensis","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133642093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Továbbá elemeztük, hogy van-e kapcsolat a marhahús zsírtartalma és zsírsav profilja között, azaz gyakorol-e bármiféle hatást a zsírsavösszetételre a hús zsírtartalmának csökkenése vagy növekedése. A húsmintákat egy helyi húsüzem boltjából szereztük be öt héten keresztül. A zsírsavösszetétel- és konjugáltlinolsav-tartalom vizsgálatot átészterezést követően lángionizációs detektorral ellátott gázkromatográffal végeztük el. A vizsgált tápanyagkomponensek esetében megállapítható volt, hogy a szarvasmarha húsrészek között – az egyszeresen telítetlen zsírsavak összege (MUFA) és az arachidonsav kivételével – nem tudtunk szignifikáns különbséget kimutatni, konjugált linolsav tartalmuk sem különbözött jelentősen egymástól. Az eltérő húsrészekből származó mérési adatokat összevontan elemezve úgy találtuk, hogy minél több zsír volt a marhahúsban, annál egészségtelenebb volt a zsírsavösszetétele, mivel arányaiban annál több telített zsírsavat (SFA) (r=0.663, P=0.001) és annál kevesebb többszörösen telítetlen zsírsavat (PUFA) tartalmazott (r=-0.621, P=0.004). Tehát elmondható, hogy a fokozott zsírbeépülés nemcsak a nagyobb zsír- és a kisebb színhús-tartalom miatt lehet káros a húsminőségre, hanem a zsírsav-profil előnytelen megváltozása miatt is. Ugyanis minél jelentősebb az elzsírosodás mértéke, annál kedvezőtlenebbé válik a zsírsavprofil, mivel növekszik a telített zsírsavak aránya a telítetlenekhez képest. Ez a tendencia már kis mintaszámú vizsgálatunkban is szignifikánsnak mutatkozott.","PeriodicalId":403816,"journal":{"name":"Acta Agraria Kaposváriensis","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126085597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each model has its specific mathematical foundations to describe physical processes in nature. Therefore, each model has its various characteristics: setting up the model, input data requirements, model calibration and verification, and output results. Water balance is still playing an important role in the effective management and use of water resources for agriculture. Based on the results of the hydrological parameter’s calculation, the water balance of the study basin can be calculated by the user or by the separated module of each model. Each hydrological models have its advantages and disadvantages. However, it is impossible to simulate hydrological processes and water balance completely accurately in nature. Still, simulation results can give us a view of the changing trend of hydrological components and the water balance. Model developers are gradually completing the shortcomings and improving the efficiency and accuracy so that the model can simulate reality with the highest accuracy. This paper sets out to review the fifteen hydrological models currently widely used in the world. Within the frame of the present study, some models are only briefly introduced; the rest are considered in more detail, from more aspects, from specific examples so that readers can decide for themselves which model is suitable for their study area and simulation needs, especially in the identity of the complex and unpredictable impacts of climate change on the agricultural sector.","PeriodicalId":403816,"journal":{"name":"Acta Agraria Kaposváriensis","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127386404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
