Megjegyzések:This pilot study used an alternative and economically efcient technique, the Kompetitive Allele-Specifc Polymerase Chain Reaction (KASP-PCR) to examine 48 SNPs from 11 parasite-resistance genes found on 8 chromosomes in 110 animals from fve sheep breeds reared in Hungary; Hungarian Tsigai, White Dorper, Dorper, Ile de France, and Hungarian Merino. Allele and genotype frequencies, fxation index, observed heterozygosity, expected heterozygosity, F statistic, and their relationship with the Hardy-Weinberg equilibrium (WHE) and the polymorphic information content (PIC) were determined, followed by principal component analysis (PCA). As much as 32 SNPs out of the 48 initially studied were successfully genotyped. A total of 9 SNPs, 4 SNPs in TLR5, 1 SNP in TLR8, and 4 SNPs in TLR2 genes, were polymorphic. The variable genotype and allele frequency of the TLRs gene indicated genetic variability among the studied sheep breeds, with the Hungarian Merino exhibiting the most polymorphisms, while Dorper was the population with the most SNPs departing from the HWE. According to the PIC value, the rs430457884-TLR2, rs55631273-TLR2, and rs416833129-TLR5 were found to be informative in detecting polymorphisms among individuals within the populations, whereas the rs429546187-TLR5 and rs424975389- TLR5 were found to have a signifcant infuence in clustering the population studied. This study reported a moderate level of genetic variability and that a low to moderate within-breed diversity was maintained in the studied populations.

Megjegyzések:A study on 51 SNPs belonging to 29 genes related to heat stress was carried out in 720 sheep from 17 different breeds adapted to different climates from Hungary, Bosnia and Herzegovina, Morocco and Romania, using Kompetitive Allele?Specific Polymerase Chain Reaction. Genotype frequency and the Hardy?Weinberg equilibrium were calculated, followed by a clustering using the Principal Component Analysis. We analyzed the polymorphisms in the following genes analyzed: HSPA12A, HSP90AA1, IL33, DIO2, BTNL2, CSN2, ABCG1, CSN1S1, GHR, HSPA8, STAT3, and HCRT. We emphasized on HSPA12A and HSPA8 genes as they were successfully genotyped in all studied flocks in which genotype frequency patterns were identified. Contrary to previous findings, the A allele for HSPA8 SNP was not observed in the heat tolerant breeds, being found exclusively in cold-tolerant breeds. The principal component analysis could not clearly differentiate the breeds, while plot concentration was slightly varied among the three groups, with HSP90AA1 and IL33 SNPs' loading values significantly contributing to PC1 and PC2. We confirmed previous works that the HSPA12A, HSPA8, HSP90AA1 and IL33 SNPs are potential candidate markers for thermotolerance adaptation in sheep. This research contributes to the genetic variability of SNPs for thermotolerance adaptability in sheep.

Megjegyzések:Dorper (DO) is a meat-specialized hair composite breed, intensively selected for growth rates, carcass quality,unselective grazing. The aim of the current comparative study was to evaluate the adaptability and performance ofDO breed under Hungarian and Romanian rearing conditions. DO breed was introduced into Hungary to DebrecenUniversity in 2008. Under Hungarian rearing conditions the DO breed maintained its non-seasonal reproduction andreproductive precocity, with maiden ewes being put to ram starting the age of 9 months. Lamb crops of 2 weaned peryear are common under proper management and feeding conditions. In Romania DO breed was introduced starting2007, with the heard-book and genetic improvement plan of the breed being established in 2009. Under Romanianfarming conditions the DO rams are usually used as terminal sires which are crossed with indigenous Turcana andTsigai breeds, being preferred by the farmers to sire the crossbreds because of the high growth rates and nonselectivegrazing of the crossbreds. Fertility of DO ewes and survival rates of the DO sired lambs until weaning werenot affected when compared to native Turcana breed. It was concluded that DO breed has adapted and performsextremely well under both Hungarian and Romanian rearing conditions.

Cím:Effects of temperament on production and reproductive performances in Simmental dual-purpose cows / Cziszter Ludovic Toma, Gavojdian Dinu, Neamt Radu, Neciu Florin, Kusza Szilvia, Ilie Daniela-Elena
Dátum:2016
ISSN:1558-7878
Megjegyzések:The aim of the current research was to evaluate the effects that temperament has on production and reproduction performances in Simmental dual-purpose cattle breed. Behavioral reactivity of cows significantly influenced (P <= 0.05) the body weight, milk yield, fat yield, protein yield, protein content, and the calving interval of the cows included in the study-head, having more substantial effects (P <= 0.001) on the milking speed and the number of steps per day, with calmer cows outperforming the nervous counterparts. However, temperament did not influence (P > 0.05) traits such as days open, number of inseminations per gestation, fat percentage, somatic cell count, body condition score, cleanliness of udder and cleanliness of hindquarter. Significant negative phenotypic correlations were found between temperament and cows body weight (-0.19), milk yield (-0.19), fat yield (-0.14), protein yield (-0.18), and milking speed (-0.18). Current results suggest that selection for calm temperaments will translate into increased milk, fat, and protein yields in Simmental cattle, as well as shorter the calving interval and improved milk ejection.

Cím:Implications of Genotype by Environment Interactions in Dairy Sheep Welfare / Dinu Gavojdian, Szilvia Kusza, András Jávor
Dátum:2014
ISSN:1841-9364 2344-4576
Megjegyzések:Small ruminants are the most extensively farmed livestock species in Europe, as a result being extremely exposed to natural hazards which leads to strong interactions between genotype and environment. Aim of the current review was to outline and discuss the main welfare issues and economic implications with regards to the genotype by environment interactions in dairy sheep. Researches concerning the additive genetic effect on milk yield, shown that this accounts only for 10%, while the milk production is 90% influenced by environmental factors, highlighting the major role that management and nutrition play in the dairy production of sheep. Nowadays, dairy sheep breeds (e.g. Eastern Friesian and Lacaune), are being introduced and reared in various countries under an extremely wide range of rearing conditions, without adequate knowledge on their acclimatization to the new specific conditions. It was concluded that a welfare assessment protocol for dairy sheep does not exist up today, moreover, there is a serious lack of data concerning the genetic and environmental factors affecting the welfare status of dairy sheep at farm level under different production systems.

Cím:Effects of behavioral reactivity on production and reproduction traits in Dorper sheep breed / Gavojdian Dinu, Cziszter Ludovic Toma, Budai Csilla, Kusza Szilvia
Dátum:2015
ISSN:1558-7878
Megjegyzések:The aim of the current research was to evaluate the effects of behavioral reactivity on production and reproduction performance in Dorper sheep, a meat breed. Temperament of animals was subjectively evaluated using a 5-point scoring system at weighing, during which sheep spent 30 seconds on the scale. The heritability of temperament was low (0.10 +- 0.03). Estimated phenotypic (rp) and genetic (rg) correlations between temperament and litter size in ewes were negative and negligible (P > 0.05) at -0.06 +- 0.18 and -0.08 +- 0.09, respectively. Significant genetic correlations were found between lamb temperament and preweaning growth rate (rg = -0.44 +- 0.07, P <= 0.05) and postweaning growth till the age of 120 days (rg = -0.52 +- 0.08, P <= 0.05). Significant genetic correlations were found between lamb temperament and growth rates during their first 3 months of age. As a result, selection for calm temperaments should translate to increased growth rates of lambs. Negative correlations between temperament and production traits, both in ewes and lambs, suggested that selection against animals that are highly reactive to improve welfare and ease of handling would not have detrimental impacts on productivity.

Megjegyzések:The objective of the current pilot study was to evaluate the reproductive performance and health indicators in Dorper, White Dorper, and Tsigai breed ewes managed semi-intensively under European temperate conditions. A total of 544 ewe-year units were observed, with ewes (ranging from 1.5 to 8 years of age) managed under identical rearing conditions for a period of two consecutive production cycles (2012 through 2013 and 2013 through 2014). In general, significant (p?0.001) genotype-related disparities were found in occurrence rates for all health parameters taken into study. Clinical mastitis incidence was significantly lower (p?0.05) in Dorper (9.4%) and White Dorper (10.8%) breeds compared to that of Tsigai ewes (17.4%). Significant differences (p?0.05) for lameness were found between Dorper and Tsigai breeds, with occurrence rates of 8.0% and 2.9%, respectively. Incidence for pneumonia and abortion was not influenced (p>0.05) by the ewes' genotype. Litter size was significantly lower (p?0.05) in White Dorper breed than for Dorper and Tsigai ewes, of 1.21, 1.40, and 1.45, respectively. Conception rates and lambs survival were not affected (p>0.05) by genotype. Results suggest that South African Dorper and White Dorper sheep breeds have adapted well to the specific rearing conditions.

Cím:Comparative study on fitness traits and reproductive efficiency in Turcana and Tsigai ewes / Gavojdian Dinu, Sauer Maria, Patras Irina, Kusza Szilvia
Dátum:2016
ISSN:2285-5750 2393-2260
Megjegyzések:Aim of the current comparative study was to evaluate health, reproductive rates and fitness indicators in Tsigai and Turcana sheep breeds reared under semi-intensive production system conditions. The project herd is consisted of 203 Tsigai (Szombor ecotype) and 226 Turcana (Sibiu ecotype) breeding ewes. The Tsigai ewes were more affected (p?0.01) by clinical mastitis compared to Turcana ewes, with an incidence of 10.8?0.21% and 3.11?1.16%, respectively. The Tsigai ewes produced significantly higher litters (p?0.001) compared to Turcana breed, 1.45?0.04% compared to 1.17?0.02%. Lambs weaning rates were not influenced by the genotype (p>0.05). This comparative study was the first attempt to provide information on the reproductive efficiency and health traits in Tsigai and Turcana breeds under temperate climate conditions found in Eastern Europe. For the selected specialized Sombor Tsigai ecotype it would be advisable to include fitness traits into the breeding selection schemes in order to improve animal welfare and overall productivity.

Cím:Effects of using indigenous heritage sheep breeds in organic and low-input production systems on production efficiency and animal welfare in Romania / Gavojdian Dinu, Padeanu Ioan, Sauer Maria, Dragomir Neculai, Ilisiu Elena, Kusza Szilvia, Rahmann Gerold
Dátum:2016
ISSN:0458-6859
Megjegyzések:Romania ranks third in the EU28 in terms of sheep numbers (9.8 millions), having a self-sufficiency for sheep meat of 150 % and therefore exports are important at national level. Objectives of the current research trials were: i) to evaluate the potential of the Turcana breed to produce organic lamb meat under highland pasture-based conditions; ii) to evaluate the overall resistance of the breed and fitness indicators, in comparison with two native breeds, reared under lowinput conditions; iii) to study the genetic base using molecular assisted selection in order to produce hypoallergenic milk and derived milk products. The conventional pasture from the current project had a potential of production of 189 kg/ha for Turcana purebreds, and of 236 kg/ha for F1German Blackheaded x Turcana (GBxTA) crossbreed lambs. While for the organic pasture, it was estimated a production potential of 191 kg of meat per hectar while rearing Turcana purebred lambs, and of 240 kg/ha for the F1GBxTA dualbreeds. In the current preliminary study, the genetic polymorphism of ovine ?-casein gene in the Romanian Zackel breed was highlighted, using TaqMan assay. ?-casein in sheep is strongly correlated to economically important milk quantitative traits, being a first step in introducing genomic selection for the production of organic hypoallergenic sheep milk and derived products.

Megjegyzések:Mastitis is the most common production disease in the dairy sector worldwide, its incidence being associated with both cows` exposure to bacteria and the cows` genetic make-up for resistance to pathogens. The objective of our study was to analyse 89 missense SNPs belonging to six genes (CXCR2, CXCL8, TLR4, BRCA1, LTF, BOLA-DRB3), which were found to be associated with genetic resistance or susceptibility to mastitis. A total of 298 cattle (250 Romanian Spotted and 48 Romanian Brown) were genotyped by Kompetitive Allele Specific PCR (KASP) and a chi-squared test was used for genetic association studies with clinical mastitis. A total of 35 SNPs (39.3%) among the selected 89 SNPs were successfully genotyped, of which 31 markers were monomorphic. The polymorphic markers were found in two genes: TLR4 (rs460053411) and BOLA-DRB3 (rs42309897, rs208816121, rs110124025). The polymorphic SNPs with MAF > 5% and call rates > 95% were used for the association study. The results showed that rs110124025 in the BOLA-DRB3 gene was significantly associated with mastitis prevalence (p ? 0.05) in both investigated breeds. Current results show that the SNP rs110124025 in the BOLA-DRB3 gene can be used as a candidate genetic marker in selection for mastitis resistance in Romanian dairy cattle.

Megjegyzések:The Eastern European Grey cattle are regarded as the direct descendants of the aurochs(Bos taurus primigenius). Nowadays in Romania, less than 100 Grey animals are being reared and included in the national gene reserve. We examined the genetic diversity among Romanian Grey, Brown, Spotted and Black and White cattle breeds, with a particular focuson Romanian Grey through the use of (i) 11 bovine specific microsatellite markers on 83 animals and (ii) 638 bp length of mitochondrial DNA (mtDNA) D-loop region sequence data from a total of 81 animals. Both microsatellite and mtDNA analysis revealed a high level of genetic variation in the studied breeds. In Romanian Grey a total of 100 alleles were found,the mean number of observed alleles per locus was 9.091; the average observed heterozygosity was 0.940; the Wright's fixation index (FIS) was negative (-0.189) and indicates that there is no inbreeding and no selection pressure. MtDNA analysis revealed 52 haplotypes with 67 variable sites among the Romanian cattle breeds without any insertion or deletion.Haplotype diversity was 0.980?0.007 and ranged from 0.883?0.056 (Brown) to 0.990?0.028 (Spotted and Black and White). The highest genetic variability of the mtDNA was recorded in the Grey breed, where 18 haplotypes were identified. The most frequent mtDNAD-loop region belonged to T3 haplogroup (80.247%), which was found across all studied breeds, while T2 haplotypes (16.049%) was only found in Grey, Spotted and Black and White genotypes. The T1 haplotypes (3.704%) were found in the Grey and Spotted. The current results contribute to the general knowledge on genetic diversity found in Eastern European cattle breeds and could prove a valuable tool for the conservation efforts of animal genetic resources (FAnGR).

Cím:Genetic characterization of indigenous goat breeds in Romania and Hungary with a special focus on genetic resistance to mastitis and gastrointestinal parasitism based on 40 SNPs / Daniela Elena Ilie, Kusza Szilvia, Maria Sauer, Dinu Gavojdian
Dátum:2018
ISSN:1932-6203
Megjegyzések:Goat breeding has become an important sector in Eastern Europe, with Romania and Hungary being among the major producer countries. Given the limited number of research done up-to-date concerning genetic studies of indigenous goat breeds reared in Romania and Hungary, the current preliminary study aimed to analyze the variability of genes related to mastitis and gastrointestinal parasitism by using Kompetitive Allele Specific PCR (KASP?). We studied 52 single nucleotide polymorphisms (SNPs) belonging to 19 genes in indigenous breeds from both countries, namely Banat's White (n = 36), Carpatina (n = 35) from Romania and Hungarian Milking (n = 79) and identified 16 polymorphic SNPs among 10 genes (PTX3, IL6, CLEC4E, IL8, IL1RN, IL15RA, TNFSF13, SOCS3, TNF and TLR3) in 150 animals. Furthermore, the diversity of the studied breeds was investigated. The PIC values ranged from 0.042 to 0.691. The mean values of observed and expected heterozygosity were 0.235 and 0.246 respectively. The highest observed heterozygosity was obtained for IL15RA g.10343904C>T in Banat's White (0.464), IL15RA g.10354813C>T in Carpatina (0.577) and SOCS3 g.52626440T>G in Hungarian Milking (0.588). Pairwise FST values between the Romanian breeds and Romanian and Hungarian breeds were small (0.009 and 0.015), indicating the close relationship among the studied goat populations. From all the polymorphic SNPs identified, the Hungarian Milking breed showed the highest proportion of polymorphisms (100%), whereas the Carpatina breed had the lowest percentage (87.5%). The highest value of MAF was obtained for SOCS3 g.52626440T>G (0.46), IL15RA g.10343904C>T (0.47), IL15RA g.10344025C>T (0.45), and IL15RA g.10354813C>T (0.42). The 16 polymorphic SNPs identified in a panel of 150 unrelated individuals belonging to three Romanian and Hungarian indigenous goat breeds could be used in future genomic based breeding schemes as markers for genetic resistance to mastitis and gastrointestinal parasitism in goat breeds found in Eastern and Central Europe.
