Cím:Heat Stress: Can Animals be Stressed but still be Healthy? / Putri Kusuma Astuti, Roland Fajardo, George Wanjala, Nelly Kichamu, Husein Ohran, Bouabid Badaoui, Zoltán Bagi, Szilvia Kusza

Megjegyzések:In this era of rapid climate change, heat stress has emerged as a major problem for sheep farming. The quantity and quality of sheep production, as well as the welfare, are all shown to be negatively impacted by heat stress. Reduced cellular immune function in sheep exposed to high temperatures increases susceptibility to various diseases,although the underlying mechanisms are unclear. The imbalance between oxidants and antioxidants, known as oxidative stress, negatively impacts animal health due to heat stress-induced impairments in immune responses, increased production of reactive oxygen species, and/or a lack of antioxidants. Heat stress in livestock has negative effects on both the cell-mediated and humoral immune responses. However, the negative effects of heat stress on immune response in sheep can vary by breed. This review discusses how heat stress affects sheep's immunity. An overview of some molecular markers related to immunity, such as interleukin (ILs), Toll-like receptors (TLRs), and also the heat stress protein (HSPs) in sheep, is also discussed. Finally, recent researchon the effects of antioxidant supplementation and other promising nutritional strategies for reducing heat stress and improving animal health is presented.

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: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:Examination of fertility indicators of European brown hares (Lepus europaeus) in Eastern Hungary / Farkas Péter, Kusza Szilvia, Balogh Péter, Majzinger István
Dátum:2020
ISSN:1018-7081 2309-8694
Megjegyzések:A decreasing tendency in the populations of the European brown hare can be observed in the whole of Europe from the mid-1960s to the present day. Among the reasons for declining populations fertility indicators of females are also mentioned. The aim of our study was to determine the reproductive parameters of the species in eastern Hungary. During the years 2015-2016, we studied two hundred animals (121?, 79?). Altogether, 121 uteri (81 adult and 40 juvenile) and 79 testicles were examined. The number of placental scars showed us the number of offspring in reproductive periods. The age of hares was estimated based on the weight of dried eye lens. The number of placental scars in the general linear model was significantly affected by hunting areas, the age of animals, the interaction of the former two, and also by body weight and kidney fat indices. The age of hares, the hunting year, the effect of the interaction of the former two, and body weight seriously contributed to the weight of the testicles. Based on the number of placental scars, 70.37% of adult and 62.50% of juvenile females were proved to be capable of reproduction. One can conclude from the above that although fertility indicators may play an important role in the decreasing trend in the numbers of Hungarian brown hare populations, they are definitely not the main causes.

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:Reproduction Efficiency and Health Traits in Dorper, White Dorper, and Tsigai Sheep Breeds under Temperate European Conditions / Gavojdian Dinu, Budai Csilla, Cziszter Ludovic Toma, Csizmár Nikolett, Jávor András, Kusza Szilvia
Dátum:2015

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:Study of LGB gene polymorphisms of small ruminants reared in Eastern Europe / Kusza Szilvia, Daniela Elena Ilie, Maria Sauer, Nagy Krisztina, Traian Stefan Atanasiu, Dinu Gavojdian
Dátum:2018
ISSN:1212-1819
Megjegyzések:The objectives of the current research were: (i) to determine the allele and genotype frequencies of the LGB gene in the sheep and goat breeds reared in Eastern Europe; (ii) to implement a comparative study in order to evaluate the milk production potential and efficiency of the main sheep and goat dairy breeds reared in Romania; (iii) to test the genetic basis and feasibility of introducing the molecular-marker assisted selection for this trait into future breeding schemes designed for small ruminants. Totally 731 purebred unrelated sheep (Turcana: 111, Racka: 98, Tsigai: 79, Karakul of Botosani: 60, Transylvanian Merino: 77) and goats (Carpatina: 82, Banat's White: 73, Saanen: 74, French Alpine: 77) were sampled and genotyped for the earlier detected alleles. The frequencies of A (0.44?0.53) and B (0.42?0.51) alleles of LGB gene were generally equal, while the C allele incidence was significantly lower for all sheep breeds studied. A relatively low or missing incidence of the C allele and no BC genotype were detected in the studied sheep breeds. All studied sheep breeds were in Hardy?Weinberg equilibrium. Gene homozygosity was lower than gene heterozygosity, with the effective allele numbers ranging from 2.00 (Transylvanian Merino) to 2.23 (Tsigai). Two alleles (A and B) and two genotypes (AA and AB) were detected in the four goat breeds studied. Allele A was the most frequent allele found in all breeds (0.57?0.68), while AB genotype had the highest frequency. Gene homozygosity was higher than gene heterozygosity, while the effective allele numbers varied between 1.76 (Banat's White) and 1.96 (Carpatina). The frequency of alleles and genotypes was similar to that reported in other Eastern sheep and goat breeds, however polymorphism has not been studied yet among these breeds in such a high number in Romania. An association study between single nucleotide polymorphisms and milk production traits should follow.
