Cím:Anti-Müllerian hormone levels in relation to ovarian structures, season and age in Lipizzaner broodmares / Eszter Angyal, Boglárka Vincze, Bence Somoskői, Viktória Sós-Koroknai, Péter Balogh, Gabriella Novotniné Dankó, Sándor Cseh, Gabriella Kútvölgyi

Megjegyzések:The anti-Müllerian hormone (AMH) is a granulosa cell-derived hormone that has been associated with female fertility and reflects the population of growing follicles. This study aimed to evaluate the average concentration of AMH in Lipizzaner mares, as well as to determine the relationship between AMH concentration and follicle number and size. We also investigated the relationship between the age of mares and their AMH levels. The possible effect of seasonality of AMH levels was also assessed. Twenty-three mares between 6 and 24 years of age were included in the experiment. Mares were divided into two groups: Group 1 included mares aged 6 - 15 years (n = 11), while Group 2 included individuals older than 15 years of age (n = 12). Venous blood was collected and ovarian activity was monitored parallelly by transrectal ultrasonography. Serum AMH concentrations varied widely between the two different groups. AMH concentrations were significantly lower in old mares than in younger animals. A positive relationship was detected between AMH concentration and the number of medium-sized follicles (P = 0.022), large follicles (P = 0.016) and the total follicle count (P = 0.026). No seasonal effect was detected.

Cím:Effect of single-nucleotide polymorphisms on specific reproduction parameters in Hungarian Large White sows / Balogh Eszter Erika, Gábor György, Bodó Szilárd, Rózsa László, Rátky József, Zsolnai Attila, Anton István
Dátum:2019
ISSN:0236-6290 1588-2705
Megjegyzések:The aim of this study was to reveal the effect of single-nucleotide polymorphisms (SNPs) on the total number of piglets born (TNB), the litter weight born alive (LWA), the number of piglets born dead (NBD), the average litter weight on the 21st day (M21D) and the interval between litters (IBL). Genotypes were determined on a high-density Illumina Porcine SNP 60K BeadChip. Data screening and data identification were performed by a multi-locus mixed-model. Statistical analyses were carried out to find associations between individual genotypes of 290 Hungarian Large White sows and the investigated reproduction parameters. According to the analysis outcome, three SNPs were identified to be associated with TNB. These loci are located on chromosomes 1, 6 and 13 (?log10P =6.0, 7.86 and 6.22, the frequencies of their minor alleles, MAF, were 0.298, 0.299 and 0.364, respectively). Two loci showed considerable association (?log10P = 10.35 and 10.46) with LWA on chromosomes 5 and X, the MAF were 0.425 and 0.446, respectively. Seven loci were found to be associated with NBD. These loci are located on chromosomes 5, 6, 13, 14, 15, 16 and 18 (?log10P = 10.95, 5.43, 8.29, 6.72, 6.81, 5.90, and 5.15, respectively). One locus showed association (?log10P = 5.62) with M21D on chromosome 1 (the MAF was 0.461). Another locus was found to be associated with IBL on chromosome 8 (?log10P = 7.56; the MAF was 0.438). The above-mentioned loci provide a straightforward possibility to assist selection by molecular tools and, consequently, to improve the competitiveness of the Hungarian Large White (HLW) breed.

Cím:Assessment of the microbiological status of two Hungarian ostrich farms / Dóra Lili Brassó, Renáta Knop, Zsófia Várszegi, Péter Bársony, István Komlósi, Árpád Bacsadi, Andrea Bistyák
Dátum:2023

Megjegyzések:The aim of this study was to estimate the occurrence of bacterial infection and contamination in two ostrich-producing farms. Compared to other poultry species, the hatchability of ostrich eggs is especially low. In a quest to identify factors that may affect hatchability, we collected faecal samples from adult birds, as well as eggs with dead-in-shell embryos, dead chicks and swab samples from the surface of the eggs and from the environment. The samples were screened for the presence of bacteria by routine bacteriological culture methods. The most prevalent bacteria, detected in the samples, were Escherichia coli, Bacillus spp. and coliform bacteria, whereas Pseudomonas spp. were less frequently found. The intensity and species compositon of the bacterial contamination was comparable in the two farms. Our results revealed that the bacteria, present in the environment, may likely be transmitted to the surface of the eggs. If they are able to penetrate the shell then the embryos and chicks become infected easily. These findings draw the attention to the special importance of enforcing efficient decontamination and disinfection measures to keep the environment and egg surface free from germs. Besides the appropriate egg treatment procedure, the incubation and hatching technology should also be kept under control.

Cím:The impact of retrieval method and breed on the motility and kinematic parameters of fresh and post-thaw ram epididymal spermatozoa / Malam Abulbashar Mujitaba, Gabriella Kútvölgyi, Viktória Johanna Debnár, Alexandra Tokár, János Posta, Szilárd Bodó, Nóra Vass

Megjegyzések:This study was conducted to develop ideal post-mortem gamete retrieval and conservation methods to establish a Hungarian ex-situ in vitro gene bank. Pairs of testes from German Mutton Merino (n 5 7) and Hungarian Black Racka (n 5 7) rams were collected at a slaughterhouse, transported to the laboratory and stored overnight (4 5 8C) before processing. Post-mortem ram epididymal spermatozoa (REPS) were obtained from the cauda epididymidis by slice or incision methods. Fresh samples were extended to 200 3 106/mL cell concentration, filled into mini straws and equilibrated at 5 8C for 2 h. Freezing was performed manually in a Styrofoam box. The fresh and post-thaw total motility, progressive motility and kinematic parameters of REPS were assessed using the CASA technique. The collection method did not significantly affect the fresh and post-thaw motility and kinematic parameters. Merino had higher (P < 0.05) testicular weight. Racka had significantly better fresh and post-thaw linear movement but had statistically the same (P > 0.05) cryotolerance as Merino. In conclusion, both collection methods were found suitable for REPS retrieval. The REPS from Racka exhibited better linear movement values than those from the Merino breed. The cryotolerance of REPS of both breeds was comparable.

Cím:Possible effect of artificial insemination and multiple ovulation embryo transfer on the health and survival of Holstein-Friesian calves / Eszter Tóth, József Rátky, János Posta, Renáta Knop
Dátum:2025
ISSN:0236-6290 1588-2705
Megjegyzések:Reproductive technologies like artificial insemination (AI) and multiple-ovulation embryo transfer (MOET) are extensively used in cattle breeding, but their effects on the health and growth of calves remain unclear. This study evaluated the effects of AI and MOET on morbidity, survival and weaning weight in Holstein-Friesian heifer calves. A total of 366 calves (AI: n 5 314; MOET: n 5 52) were followed for 91 days from birth. Morbidity was classified based on the incidence and severity of diarrhoeal and respiratory disease. Weaning weights were contrasted with disease incidence. Statistical analyses included chi-square tests for categorical data and ANOVA for continuous data (P < 0.05). Survival and overall morbidity rates were not influenced greatly by reproductive technology. The prevalence of diarrhoeal disease was similar for MOET and AI groups (P > 0.05), but respiratory disease was greater and more severe in MOET calves (P < 0.05). Morbidity negatively impacted weaning weight in AI calves (P < 0.05) but had no significant impact on MOET calves. Season and colostrum quality significantly influenced survival, with greater survival rates noted for autumn-born calves and calves that received high-quality colostrum (>25% IgG) (P < 0.05). While reproductive technology had little effect on survival, MOET calves showed a heightened susceptibility to respiratory illnesses, highlighting the importance of targeted health management.
