Megjegyzések:The adverse effects of climate change on sheep farming have become more noticeable in recent decades. Extensive efforts have been made to untangle the complex relationship between heat tolerance, animal health, and productivity, also to identify a resilient and economically suitable breed for selection that can be resilient to future climate change conditions. Using quantitative real-time polymerase chain reaction (qRT-PCR), we observed the seasonal variations in the expression of several important genes related to heat stress and immunity (HSP70, IL10, TLR2, TLR4, and TLR8) in three of the most widely kept sheep breeds in Hungary: The indigenous Tsigai, Hungarian Merino, and White Dorper. We found that the seasonal stressor affected the relative gene expression of all genes in this study. Notably, The Hungarian indigenous Tsigai was the most robust breed adapted to the Hungarian continental (hot summer, cold winter) environment, with excellent thermotolerance and immunity. Furthermore, despite suffering from heat stress in the summer, Hungarian Merino maintained their robust immune system well throughout the year.

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.

Cím:Coping with climate change; is white sheep more favorable than black? = Szembenézni az éghajlatváltozással; kedvezőbb a fehér bárány a feketénél? : a review = irodalmi áttekintés / Putri Kusuma Astuti, George Wanjala, Zoltán Bagi, Szilvia Kusza
Dátum:2022
ISSN:0230-1814
Megjegyzések:Climate change and its impact on livestock production are a point of discussion nowadays. The impact of climate change, heat stress mainly, is negatively correlated to livestock production. In sheep, heat stress causes disruptions in the biological and physiological activities inside the body, resulting in hormonal imbalance, lower body growth and production, and reproduction impairment. Furthermore, the stress caused by the thermal condition does not promote animal welfare in the sheep population. Genetic factors determine coat color, and numerous genes have been identified as associated with it, including TRYP, MC1R, MLANA, OCA2, and others. Numerous studies indicate that light coat colors promote adaptation to hot environments owing to their ability to reflect sunlight more effectively than dark coat colors. Regardless, other research found no difference in adaption to a hot environment between light and dark coat colors. In the present work, authors summarized the effect of light and dark coat colors. Az éghajlatváltozás és annak az állattenyésztésre gyakorolt hatása manapság vita tárgyát képezi. A klímaváltozás hatása, elsősorban a hőstressz negatívan hat az állattenyésztésre. A juhokban a hőstressz megzavarja a szervezeten belüli biológiai és élettani tevékenységeket, ami hormonális egyensúlyhiányt, kisebb testnövekedést és termelést, valamint szaporodási zavarokat okoz. Továbbá a termikus állapot okozta stressz hátrányosan hat az állatjólétre is. Genetikai tényezők határozzák meg a gyapjú színét, és számos gént azonosítottak, amelyek kapcsolatba hozhatóak annak kialakulásával, köztük a TRYP, MC1R, MLANA, OCA2 stb. A gyapjúszín kialakulása a bőr epidermiszében található melanociták által termelt kétféle pigmenttől függ. Számos tanulmány kimutatta, hogy a világos szőrszínek elősegítik a meleg környezethez való alkalmazkodást, mivel hatékonyabban verik vissza a napfényt, mint a sötét színek. Ettől függetlenül más kutatások nem találtak különbséget a forró környezethez való alkalmazkodásban a világos és a sötét szőrzet színei között. Sajnos jelenleg nem ismert, hogy a sötét és világos gyapjú miben tér el hőszabályozási mechanizmusaiban a hőstressz hatására. A szerzők jelen tanulmányukban összegezni kívánták a világos és sötét gyapjú hatását.

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:Understanding the responses of animals to seasonal heat stress on the genomic level has led to the identification of genes implicated in thermal stress reaction mechanisms. In this study, the relative gene expression of Interleukin-10 (IL-10), an anti-inflammatory cytokine and biomarker for heat stress-mediated immune modulation, was observed during the summer and winter seasons in continental and tropical sheep breeds, namely, Hungarian Indigenous Tsigai and White Dorper, employing quantitative real-time polymerase chain reaction (qRT-PCR). Temperature-humidity indices (THI) were calculated to assess heat stress levels. The results indicate that IL-10 CT-values were significantly higher during the summer, when heat stress prevails, in both sheep breeds compared to winter. While the White Dorper exhibited a higher numerical value for the summer relative gene expression ratio (16.2) compared to the Hungarian Indigenous Tsigai (12.3), no significant differences in CT values were observed between breeds or among sexes. These findings suggest the immune-adaptive characteristics of the two sheep breeds during seasonal heat stress. The variation of IL-10 gene expression levels between the two breeds can be attributed to their geographical origins; the White Dorper emerging from arid subtropical South Africa and the Hungarian Indigenous Tsigai Sheep thriving in the seasonally harsh Carpathian climate for centuries.

Cím:Livestock breeding for welfare, adaptation and sustainability : an overview of the novel traits and breeding concerns in sheep, dairy, beef and poultry / George Wanjala ; Putri Kusuma Astuti ; Bagi Zoltán ; Strausz Péter ; Kusza Szilvia
Dátum:2023
ISSN:0230-1814
Megjegyzések:The principal goal of an animal breeder is to produce the next generation of progeny that has superior performance than the average of the parent population. Previously, genetic selection for traits to be improved emphasized functional traits of economic value. However, little attention was given to sustainability principles or breeding for sustainability (environmental sustainability, animal welfare, and consumer preferences). Thus, the current concerns on principles of sustainability have necessitated breeders to incorporate novel traits into the breeding program. Most of these novel traits have low heritability, and in some cases, they correlate with traits that compromise with the principle of breeding for sustainability. Therefore, using breeding techniques provides an opportunity for enhanced genetic gain in traits of interest as well as difficult to measure traits.This literature review provides an overview of sustainable animal breeding, strategies, and the current concerns by discussing market trends of livestock products, new considerations and traits for sustainable animal breeding or novel traits, new techniques in animal breeding, and genetic diversity in domestic animals focusing on selected animals including sheep, dairy, beef, and chicken breeding. Understanding animal breeding trends, the potential market structure for animal products, new technologies in animal breeding, and consumer concerns help in developing a sustainable farm animal breeding program to meet an ever-increasing food security demand.

Cím:Assessing the genomics structure of Dorper and White Dorper Variants, and Dorper Populations in South Africa and Hungary / George Wanjala, Putri Kusuma Astuti, Zoltán Bagi, Nelly Kichamu, Péter Strausz, Szilvia Kusza
Dátum:2023
ISSN:2079-7737
Megjegyzések:Simple Summary: The Dorper sheep breed was created to thrive in harsh environments in South Africa. Two breed variants were developed in the selection process. The breed gained popularity and was exported to several regions of the world where it is reported to be doing better than the purported locally adapted sheep breeds. To enhance the performance of other native sheep breeds, Dorper is widely utilized in crossbreeding with native breeds. There has not been any research done to examine the genomic status of Dorper in South Africa and Dorper in other places outside of South Africa. The genomic architecture of white Dorper and Dorper from South Africa and Hungary are compared in this study. White Dorper, Dorper, and Dorpers from South Africa and Hungary all have significantly distinct genomes. Different environmental factors and variations in coat color could be the cause of the genetic variations. Abstract: Dorper sheep was developed for meat production in arid and semi-arid regions under extensive production systems in South Africa. Two variants with distinct head and neck colors were bred during their development process. White Dorper have a white coat while Dorper have a black head and neck. Both variants have grown in popularity around the world. Therefore, understanding the genomic architecture between South African Dorpers and Dorper populations adapted to other climatic regions, as well as genomic differences between Dorper and White Dorper variants is vital for their molecular management. Using the ovine 50K SNP chip, this study compared the genetic architecture of Dorper variants between populations from South Africa and Hungary. The Dorper populations in both countries had high genetic diversity levels, although Dorper in Hungary showed high levels of inbreeding. White Dorpers from both countries were genetically closely related, while Dorpers were distantly related according to principal component analysis and neighbor-joining tree. Additionally, whereas all groups displayed unique selection signatures for local adaptation, Dorpers from Hungary had a similar linkage disequilibrium decay. Environmental differences and color may have influenced the genetic differentiation between the Dorpers. For their molecular management and prospective genomic selection, it is crucial to understand the Dorper sheep`s genomic architecture, and the results of this study can be interpreted as a step in this direction.

Cím:A review on the potential effects of environmental and economic factors on sheep genetic diversity : consequences of climate change / George Wanjala, Putri Kusuma Astuti, Zoltán Bagi, Nelly Kichamu, Péter Strausz, Szilvia Kusza
Dátum:2023
ISSN:1319-562X 2213-7106
Megjegyzések:Climate change has a significant effect on the productivity of livestock including milk, meat, and reproduction. This could be attributed to the internal diversion of energy resources towards adaptive mechanisms. Among the climate change variables, thermal stress seems to be the major limiting factor in animal agriculture. A better understanding of the effects of climate change-influenced ecological factors on the genetic diversity of livestock species is warranted. Sheep is an ideal livestock species to be used in investigating environmental adaptation due to its wide range of agroecological habitats, genetic and phenotypic variability. There is a heavy reliance on sheep genetic diversity for future animal protein security, but the implications of climate change on their genetic diversity receive less attention. Here, the potential environmental factors influencing natural selection in sheep populations are presented. We argue that prolonged exposure to these factors plays a major role in influencing the development of adaptation traits in indigenous sheep breeds, consequently leading to the alteration of genetic diversity at specific loci. The factors discussed include hot temperatures (heat stress), insufficient water, low quantity and quality of forage, and prevalence of parasites, pests, and diseases. In addition, genetic diversity, some signatures of selection for adaptation and economic angles of selection are also briefly discussed. A better understanding of environmental factors influencing the genetic diversity of sheep populations will inform breeding and management programs and may offer an opportunity for greater production efficiency with low input costs.
