Khloud M. Algothmi, Zeinab M. H. Mahasneh, Sameh A. Abdelnour, Qahtan A. W. Khalaf, Ahmed E. Noreldin, Rasha A. Barkat, Norhan E. Khalifa, Asmaa F. Khafaga, Guillermo Tellez-Isaias, Abdulmohsen H. Alqhtani, Ayman A. Swelum, Mohamed E. Abd El-Hack

Summary: Heat stress is a crucial factor affecting the poultry industry, and it can induce mitochondrial dysfunction in broilers. Studies have shown that heat stress can disrupt mitochondrial function by causing redox imbalance, increasing uncoupling protein, promoting lipid and protein oxidation, and oxidative stress. To combat the negative effects of heat stress, enriching broiler diets with mitochondria enhancers can boost mitochondrial functionality.

Detection and identification of foot-and-mouth disease O/ME-SA/Ind-2001 virus lineage, Indonesia, 2022

Edy Budi Susila, Rosmalina Sari Dewi Daulay, Dewi Noor Hidayati, Sapto Rini Budi Prasetyowati, Ernes Wriningati, Ernes Andesfha, Sri Handayani Irianingsih, I. Nyoman Dibia, Yuni Faisal, Arif Supriyadi, Yuni Yupiana, Muhammad Muharram Hidayat, Nuryani Zainuddin, Hendra Wibawa

Summary: This study reports the detection and identification of serotype O foot-and-mouth disease viruses in Indonesia. These viruses belong to the ME-SA/Ind-2001e lineage and have 95.3% nucleotide sequence similarity to Ind-2001e viruses from other Asian countries. The illegal trade of live animals from Southeast Asia may be a possible route for the introduction of foot-and-mouth disease in Indonesia, but further investigation is needed.

Seroprevalence of brucellosis in dairy animals and their owners in selected sites, central highlands of Ethiopia

Temesgen Kassa, Beksisa Urge, Gezahegn Mamo

Summary: A cross-sectional study was conducted to determine the seroprevalence and identify risk factors of brucellosis in dairy cows and owners. The results showed an overall seroprevalence of 0.61% for bovine brucellosis and 1.21% for human brucellosis. Risk factors such as late stage of abortion, retained fetal membrane, market-based stock replacement, and presence of parturition pen were significantly associated with seropositivity in dairy cattle. For human brucellosis, risk factors included human housing, contact with aborted fetus, and drinking raw milk from infected cows.

Daniel Prois Flores, Dirleise Pianesso, Eduardo Kelm Battisti, Suziane Ghedini Martinelli, Isadora Liberalesso de Freitas, Joao Raduenz Neto, Leila Picolli da Silva, Rafael Aldrighi Tavares, Rafael Lazzari

Summary: A feeding trial was conducted to assess the effects of dietary L-threonine supplementation on the growth and body composition of fingerlings Rhamdia quelen. The results showed that different levels of threonine had an impact on the analyzed variables. Fish fed with lower levels of threonine had lower growth and body deposition of nutrients, as well as higher hepatosomatic index scores and changes in plasmatic metabolite concentrations. The ideal level of threonine in the diet was determined through regression analysis.

Identifying key DNA methylation sites and their cis-methylation quantitative loci for intramuscular fatty acid traits using genome and methylome data in Yorkshire pigs

Qi Shen, Kai Wang, Shujie Wang, Zhenjian Zhao, Xiang Ji, Dong Chen, Yang Yu, Shengdi Cui, Junge Wang, Ziyang Chen, Yiren Gu, Guoqing Tang

Summary: In this study, DNA methylation in muscle tissue samples from 140 Yorkshire pigs was analyzed using RRBS. Associations between DNA methylation and fatty acid traits were found, with some associations specifically identified by EWAS. GWAS was performed to identify meQTLs using significantly methylated CpGs from EWAS, revealing the predominance of trans-meQTLs and a cis-meQTL on SSC12. A crucial CpG site and its cis-meQTL on SSC12, located near the FASN gene, were reported. These findings contribute to the understanding of the molecular mechanisms underlying fatty acid traits in pigs.
