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.

Megjegyzések:	Shunt fostering, also known as fall-behind management, is a unique piglet management strategy in commercial pig farming. We investigated the effects of shunt fostering on sow backfat thickness and piglet weaning. Seventeen sows were prospectively used for shunt fostering. Backfat thickness was measured at farrowing, early weaning (EW), and final weaning (FW). The results showed that the mean parity of sows utilized for shunt fostering was 3.4 ? 0.7. At farrowing, EW and FW, the mean backfat was 14.52 mm ? 2.7, 11.65 mm ? 2.23, and 10.06 mm ? 2.14, respectively. Backfat thickness differed (p<0.05) from farrowing to weaning; however, there was no difference (p>0.05) in backfat changes during weaning times. Sows used in shunt fostering lost 13.7% of their backfat within that period and 33.5% during the entire lactation period. There was a difference (p < 0.05) in the number of weaned piglets during EW (13.18) and FW (12.41). Spearman's correlation established a positive but non-significant relationship between backfat thickness at farrowing and number of live born (?=0.336, p>0.05). In conclusion, shunt fostering is meant to increase piglet survival, and these findings underscore the importance of focusing on aspects of management that could improve the efficiency of shunt fostering.
