In the article, we propose a probit-based progressive shift alternative that is more realistic than the simple shift alternative for skewed non-negative data that occur in many research areas. Our motivation comes from parasitology. The progressive shift alternative is used to compare the power of six location-scale tests and seven commonly used location tests for several skewed theoretical and empirical parasite distributions. It is shown that location-scale tests are more powerful than location tests.

The aim of our study was to examine the associations of management practices and reproductive performance in Holstein cows on large commercial dairy farms. Management practices applied to cows were surveyed between 22 May and 6 November 2015 in 34 large Holstein-Friesian dairy herds in Hungary. Individual data of 23 784 cows that calved between 1 January 2014 and 31 December 2014 in the surveyed herds were gathered. Associations between the management practices and the reproductive parameters were analyzed by mixed effects models. Regarding heat abatement we found that ventilation with sprinklers was associated with the shortest breeding interval (P0.05) results to lack of heat stress protection. It was also revealed, that lack of a well-established voluntary waiting period (VWP) or a VWP shorter than 50 days was associated with less days to first service (P<0.01), shorter breeding interval (P<0.01) and calving to conception interval (P<0.05), as well as higher odds of carrying a calf by 200 days in milk (P<0.01) compared with those using a VWP of at least 50 days. Those farms that applied transrectal ultrasonography were more likely to use ventilation with sprinklers (P<0.05), hormonal synchronization (P<0.01) and to perform early pregnancy diagnosis followed by pregnancy recheck (P<0.05). The application of transrectal ultrasonography with one of the aforementioned practices was associated with reduced days to first service (P<0.05), shorter breeding interval (P<0.05) and higher odds of pregnancy at 200 days in milk (P<0.05). Our study highlights the management practices most closely related to improved reproductive performance, which are, therefore, suggested to be applied on dairy farms, considering the local circumstances of the individual farms.}, year = {2018}, eissn = {1571-732X}, pages = {2401-6}, orcid-numbers = {Abonyi-Tóth, Zsolt/0000-0002-5585-3313} } @article{MTMT:3338066, title = {Holstein-fríz tenyészüszők szaporodásbiológiai menedzsmentje és mutatói nagy létszámú hazai tehenészetekben}, url = {https://m2.mtmt.hu/api/publication/3338066}, author = {Fodor, István and Baumgartner, Walter and Monostori, Attila and Abonyi-Tóth, Zsolt and Ózsvári, László}, journal-iso = {MAGY ALLATORVOSOK}, journal = {MAGYAR ÁLLATORVOSOK LAPJA}, volume = {140}, unique-id = {3338066}, issn = {0025-004X}, year = {2018}, pages = {67-74}, orcid-numbers = {Abonyi-Tóth, Zsolt/0000-0002-5585-3313} } @article{MTMT:3322722, title = {Associations between management practices and major reproductive parameters of Holstein-Friesian replacement heifers}, url = {https://m2.mtmt.hu/api/publication/3322722}, author = {Fodor, István and Baumgartner, W and Abonyi-Tóth, Zsolt and Lang, Zsolt and Ózsvári, László}, doi = {10.1016/j.anireprosci.2017.11.015}, journal-iso = {ANIM REPROD SCI}, journal = {ANIMAL REPRODUCTION SCIENCE}, volume = {188}, unique-id = {3322722}, issn = {0378-4320}, abstract = {The aim of this study was to assess the relationship between the reproductive management practices and the performance of replacement heifers on large commercial dairy farms. The individual data of 14,763 heifers, first inseminated in 2014, were analysed from 33 Holstein-Friesian dairy herds in Hungary. The relationships between management practices and major reproductive parameters (age at first service, AFS; age at first calving, AFC; conception risk to first insemination, CR1; and pregnancy status at 20 months of age) were examined by mixed-effects models, with the herd as the random effect. The results showed that farms using oestrus detection aids experienced reduced AFS (p < 0.001) and AFC (p = 0.001). Observation of oestrus for shorter periods instead of continuously showed a tendency towards lower AFC (p = 0.057) and was associated with higher odds of pregnancy at 20 months of age (p = 0.020). Heifers on farms using sexed semen had younger AFS, but poorer CR1, compared to those using conventional semen exclusively (p < 0.05). In addition, the odds of heifers being pregnant by 20 months of age was higher on farms with more experience using sexed semen (p = 0.020). Frequent pregnancy diagnosis (i.e. more than once per week) was associated with younger AFC (p = 0.023). Our results suggest the use of certain advanced reproductive management practices for heifer reproductive management in large dairy herds (e.g. oestrus detection aids), which can improve reproductive efficiency considerably, but are currently used only to a limited extent. © 2017 Elsevier B.V.}, keywords = {Age at first calving; Reproductive management; Pregnancy diagnosis; Oestrus detection; Dairy heifer}, year = {2018}, eissn = {1873-2232}, pages = {114-122}, orcid-numbers = {Abonyi-Tóth, Zsolt/0000-0002-5585-3313} } @article{MTMT:3316345, title = {Temporal changes in floral resource availability and flower visitation in a butterfly}, url = {https://m2.mtmt.hu/api/publication/3316345}, author = {Szigeti, Viktor and Kőrösi, Ádám and Harnos, Andrea and Kis, János}, doi = {10.1007/s11829-017-9585-6}, journal-iso = {ARTHROPOD-PLANT INTE}, journal = {ARTHROPOD - PLANT INTERACTIONS}, volume = {12}, unique-id = {3316345}, issn = {1872-8855}, keywords = {LEPIDOPTERA; Foraging behaviour; resource selection; Parnassius mnemosyne; Nectar plant; Clouded Apollo}, year = {2018}, eissn = {1872-8847}, pages = {177-189}, orcid-numbers = {Kőrösi, Ádám/0000-0003-1528-1872; Kis, János/0000-0001-9354-1292} } @article{MTMT:3312188, title = {Univerzális, ivarhatározáshoz használt CHD1 markerek alkalmazhatósága különböző madárrendekben}, url = {https://m2.mtmt.hu/api/publication/3312188}, author = {Ágh, Nóra and Kovács, Szilvia and Nemesházi, Edina and Szabó, Krisztián}, journal-iso = {MAGY ALLATORVOSOK}, journal = {MAGYAR ÁLLATORVOSOK LAPJA}, volume = {140}, unique-id = {3312188}, issn = {0025-004X}, year = {2018}, pages = {47-59}, orcid-numbers = {Ágh, Nóra/0000-0001-9184-912X; Nemesházi, Edina/0000-0002-0179-1153} } @article{MTMT:3269304, title = {Bias-corrected estimation of the Rudas–Clogg– Lindsay mixture index of fit}, url = {https://m2.mtmt.hu/api/publication/3269304}, author = {Reiczigel, Jenő and Ispány, Márton and Tusnády, Gábor and Michaletzky, György and Marco, Marozzi}, doi = {10.1111/bmsp.12118}, journal-iso = {BRIT J MATH STAT PSY}, journal = {BRITISH JOURNAL OF MATHEMATICAL & STATISTICAL PSYCHOLOGY}, volume = {71}, unique-id = {3269304}, issn = {0007-1102}, abstract = {Rudas, Clogg, and Lindsay (1994, J.

It is the lowest proportion of contamination' which, if removed from the population or from the sample, makes the fit of the model perfect. The mixture index of fit has been widely used in psychometric studies. We show that the asymptotic confidence limits proposed by Rudas etal. (1994, J. R Stat Soc. Ser.
