Background: Bovine alphaherpesvirus 1 (BoHV-1) is a serious disease with severe negative economic effects on the global cattle sector, especially in Iran.

Objective: This cross-sectional study was carried out to examine the seroprevalence and associated risk factors of BoHV-1 infection with progesterone levels and embryo death in 30-day pregnant dairy cattle at Zagros Industrial Dairy Farm in Shahrekord, Iran.

Methods: Between December 2017 to February 2018, blood samples were obtained from 60 dairy cow herds. To determine whether BoHV-1 was present, serum samples were examined using the ELISA for serum antibodies. To find progesterone (P4) in blood, the progesterone ELISA test was used.

Results: 96.7 % of sera tested positive for BoHV-1 antibodies, according to the findings. Additionally, 60.34 % of blood samples that tested positive had an experience of abortion and significantly more inseminations that resulted in pregnancy, consistent with findings from other studies conducted in Iran and other nations.

Conclusions: Since this study is the first to document the risk factor for BoHV-1 infection in Shahrekord, Iran, we could infer that the virus is extensively dispersed in this area.

Heat stress has been proven to cause negative effects on livestock leading to lower productivity and economic value. Understanding how heat stress manifests within an animal's body is the first step in devising a heat stress mitigation strategy; transcriptomic studies are one of the methods used. Here, using a systematic literature review methodology, we examine the recent decade of transcriptomics' application to the study of livestock adaptation.

Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis, an oncogenic deltaretrovirus that has emerged as a potential zoonotic infection. The BLV naturally infects cattle and causes economic losses through a slow persistent infection with various clinical symtoms following preleukosis. The main objective of this study was to determine the seroprevalence of BLV antibodies in cattle and buffaloes in the border provinces of the Eastern Anatolia region, Türkiye, using the agar gel immunodiffusion (AGID) assay and enzyme-linked immunosorbent assay (ELISA).

Influenza, a major "One Health" threat, has gained heightened attention following recent reports of highly pathogenic avian influenza in dairy cattle and cow-to-human transmission in the USA. This review explores general aspects of influenza A virus (IAV) biology, its interactions with mammalian hosts, and discusses the key considerations for developing vaccines to prevent or curtail IAV infection in the bovine mammary gland and its spread through milk.

Bovine coronavirus (BCoV), a significant cattle pathogen causing enteric and respiratory diseases, is primarily detected using reverse transcription-polymerase chain reaction. Our objective was to develop a novel detection method for BCoV by matrix-assisted laser desorption/ionization‒time-of-flight mass spectrometry (MALDI-TOF MS). Peptide mass fingerprint analysis revealed that nucleocapsid (N), membrane (M), and hemagglutinin-esterase (HE) were three main BCoV proteins.

Fatty liver impairs liver function and reduces productivity in dairy cows. Our previous in vivo findings demonstrated that branched-chain amino acids (BCAA) or branched-chain ketoacid (BCKA) improved liver function and lactation performance in dairy cows; however, the underlying mechanisms remain unclear. This study aimed to assess the impact of BCAA or BCKA supplementation on intracellular triglyceride (TG) accumulation, lipid metabolism, antioxidant response, and apoptosis in hepatocytes.
