Vaccine sero-monitoring and sero-surveillance of Peste des petits ruminants in small ruminants in West Gojjam zone, Amhara region, Ethiopia.
Front Vet Sci
December 2024
Department of Health Biotechnology, Bio and Emerging Institute Technology, Addis Ababa, Ethiopia.
Background: Peste des petits ruminants (PPR) is an acute or subacute, highly contagious, and economically important, transboundary disease of small ruminants caused by Peste des petits ruminants virus (PPRV).
Objectives: The objective of this study was to determine the seroconversion rate in PPR vaccinated flock of sheep (Sekela district) and the seroprevalence of PPRV in unvaccinated flocks of sheep and goats (Yilmanadensa district).
Methods: A cross-sectional study was conducted from January to March 2022 in two selected districts of West Gojjam zone, Ethiopia.

Article Synopsis
- Disorders of acid-base balance in the rumen of dairy cows can notably influence their health and performance, particularly in relation to subacute ruminal acidosis (SARA) and the production of inflammatory compounds like lipopolysaccharides (LPS).
- This study compared 40 Holstein dairy cows based on their rumen pH levels two to four hours after feeding, categorizing them into low pH (LPH) and high pH (HPH) groups, to analyze the relationship between pH, microbiomes, and inflammatory responses.
- The findings indicated that cows in the LPH group exhibited higher concentrations of various fatty acids and inflammatory markers, along with significant changes in microbial populations, which suggests that lower rum
Quantitative Analysis of Deer Bone Hydroethanolic Extract Using Label-Free Proteomics: Investigating Its Safety and Promoting Effect on Mouse Embryonic Osteoblastic Progenitor Cell Proliferation.

College of Chinese Medicinal Material, Jilin Agricultural University, Changchun 130118, China.
Article Synopsis
- Deer bone is a nutritious resource rich in proteins and amino acids that may help strengthen bones and provide antioxidants, but its utilization and safety as a health food remain underexplored.
- The researchers developed a hydrogen ethanol extraction method for deer bone and used advanced analytical techniques (like LC-MS/MS and GC-MS) to study its components, identifying numerous proteins, amino acids, fatty acids, and inorganic elements.
- Safety evaluations showed that the deer bone hydroethanolic extract (DBHE) is non-toxic and may enhance the growth of bone-forming cells, suggesting its potential for treating conditions like osteoporosis and arthritis.
Site Matters: Differences in Gene Expression Profiles Along the Bovine Rumen Papilla During Subacute Rumen Acidosis.
Int J Mol Sci

Centre for Animal Nutrition and Animal Welfare Sciences, University of Veterinary Medicine Vienna, Veterinärplatz 1, 1210 Vienna, Austria.
Subacute rumen acidosis (SARA) is a significant concern in dairy cattle fed grain-rich diets. To elucidate the underlying pathophysiological mechanisms, ruminal papilla biopsies are often used. This study aimed to assess how the sampling site along the ruminal papilla influences gene expression profiles in rumen epithelium during SARA.

This study aimed to explore the effects of sodium butyrate on liver metabolism in goats subjected to a high-concentrate diet. We randomly assigned twelve Saanen-lactating goats into two groups, one of which received a high-concentrate diet (concentrate: forage = 60:40, control group), while the other received the same basal diet supplemented with sodium butyrate (SB) (10 g/kg basal diet, SB group). Compared with the control diet, the SB diet considerably increased the milk fat percentage and content ( < 0.
