Cím:	Grazing on mountain pastures-does it affect meat quality in lambs? / T. Adnoy, A. Haug, O. Sbrheim, M.S. Thomassen, Z. Varszegi, L.O. Eik

Megjegyzések:	Meat from lambs raised on mountain pastures without any supplementary feeding or treatment is often considered to be of superior quality. Hence, the objective of this study was to compare the quality of meat from lambs grazing on unimproved mountain range (1000 m above sea level) with meat from lambs grazing on cultivated lowland pastures. The experiment was undertaken in Hardanger on the Western Coast of Norway with 150 Norwegian Crossbred Sheep (Norsk Kvitsau) randomly allocated to bLowlandQ and bMountainQ groups. Twenty lambs from each group were selected for final evaluation. Slaughtering and grading were performed at a commercial slaughterhouse. Thereafter, loin samples of M. longissimus dorsi were analyzed for sensory traits and other meat quality. For further comparisons, loin samples were also taken from lambs slaughtered at two other locations in Norway. Significant differences between the groups were found in grading, fat content and fatty acid composition, meat colour, and meat flavour. Differences in sensory traits were in general small and most likely not noticed by the consumer. Still the results suggest that meat from lambs raised in extensive systems on mountain range has certain qualities that might be used in promotion of local and regional products.

Cím:	Investigation of polymorphisms and association of the ABCG2 gene with milk production traits in sheep / M. Árnyasi, I. Komlósi, M. P. Kent, L. Czeglédi, G. Gulyás, A. Jávor

Megjegyzések:	The ATP-binding casette sub-family G member 2 (ABCG2) gene was chosen as a candidate gene influencing milk production traits in sheep based on its function and chromosomal localization. A number of fragments were sequenced, including the 3·UTR region, 16 exons, and regions within introns 4, 5 and 6, in samples collected from 11 Awassi and 2 Gyimesi Racka sheep. A single 35-base insertion/deletion, and a total of 13 single nucleotide polymorphisms (SNPs) were identified. SNP mutations found in exons (n=3) were synonymous. Two SNPs (g.703T>C, c.863+40G>A) and the insertion/deletion (c.683-80_46del) were chosen for further investigation, and an association study between these three polymorphisms and milk production traits was performed in both breeds (Awassi n=310, Gyimesi Racka n=75). The analysis revealed significant effect of two of the studied SNPs in Gyimesi Racka. Mutation g.703T>C showed significant effect on protein percentage (p<0.05) while the c.683-80_46del had a significant effect on somatic cell score (p<0.01). However, further studies are needed to evaluate these possible associations more effectively.

Cím:	Longevity analysis of the Pannon White rabbit does / János Posta, Zs. Gerencsér, Zs. Matics, G. Mészáros, I. Nagy
Dátum:	2026
ISSN:	1871-1413
Megjegyzések:	The aim of this study was to analyse the number of kindlings of Pannon White rabbit does, to get information about the risk factors affecting their reproductive performance success and to evaluate the suitability of this trait as a possible selection criterion. The pedigree information was supplied by the experimental farm of the Hungarian University of Agriculture and Life Sciences, who is responsible for the maintenance of the Pannon White rabbit breed. Total kindling number of 3371 Pannon White rabbit does born from 2000 up to 2022 were used in the analysis. Year-season and number of kits born alive were considered as fixed time dependent effects in the model and they both were significant (P < 0.001). The genetic variance was estimated to calculate the heritability for longevity. To demonstrate the extent of differences within the population, the ten best and worst bucks were compared based on the estimated risk of culling to check genetic differences. As number of kits born alive increased, the culling risk for this parameter decreased. After adjusting for the fixed effects, the estimated heritability of the total kindling number was h2 = 0.14 (s.e. 0.034). The offspring of ten best and ten worst bucks were compared, revealing convincing evidence of principle that selection on this trait has a potential to improve the longevity of the Pannon White rabbits.

Megjegyzések:	The aims of the current research were to evaluate the quality of the pedigree, generation interval, gene origin, inbreeding, and effective population size of the current Pannon White rabbit breeding population. The pedigree information was supplied by the experimental farm of the Hungarian University of Agriculture and Life Sciences, who is responsible for the maintenance of the Pannon White rabbit breed. The studbook data of the registered animals up to 2022 were analysed. The active population in 2022 was chosen as the reference population for the current study. The complete generation equivalent was 12.11 whereas the average maximum generations was 39.15 for the reference population. All animals of the breeding stock were inbred, the average Wright's inbreeding coefficient was 12.52 %. Kalinowski's decomposition of inbreeding showed that inbreeding is orig- inated mainly from the past. The proportion of rabbits having more than 30 GCI was above 30.02 % for the total population, whereas it was above 36.45 % for the reference population
