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:	Sow and piglet behaviour during lactation: A review focusing on selected behaviour manifested by foster sows and their fostered piglets / Joab Malanda Osotsi, Yogi Sidik Prasojo, Putri Kusuma Astuti, Mequanint Gashew, Peter Balogh, Jozsef Ratky, Gabriella Novotni-Danko

Megjegyzések:	Foster (F) sows are used to nurse piglets from other sows. Nurse (N) sows are used to nurse other piglets after weaning their own piglets during lactation. Sows nursing non-biological piglets can reject or attack unfamiliar piglets. Similarly, N/F sows could fail to recognize the adopted piglets, which may result in delayed or denied suckling. Behaviours such as rejection, aggression, and failure to suckle pose both physical and nutritional challenges to the fostered piglets. Therefore, after collating the literature, this review was able to establish the following: nurse or foster sows showed antagonistic behaviour towards adopted piglets through aggression and discrimination. Similarly, N/F sows terminated nursing bouts more frequently than non-N/non-F sows. Most N/F piglets upon encountering N/F sows showed wandering squealing syndrome with escape attempts. Nurse/foster piglets exhibited more post-teat massage behaviour, a sign of ♭begging for more milk.' Resident piglets frequently attacked fostered piglets through fighting. Management of large litters in pig production entails the use of N/F sows, and the knowledge in this review could help in improving N/F sow production systems, especially on lactational behaviour. Explanations of possible interventions that are likely to reduce negative behaviours among foster sows and their piglets has been given.
