Polysaccharides derived from Fisch possess diverse activities, making them a potential prebiotic candidates for enhancing lamb health. This study investigated the immunomodulatory effects of Fisch polysaccharides from Aksu (AK) and Shanshan (SS) regions on sheep lambs. The results showed that sheep lambs in the SS group exhibited significantly increased ( < 0.05) average daily gain, levels of growth hormone (GH), insulin (INS), IgA and IgM, and cytokines IL-4, IL-10, IL-17, TNF-α and IFN-γ compared to those in the control check (CK) group. Moreover, the SS treatment significantly increased the diversity and abundance of beneficial bacteria, while concurrently diminishing the prevalence of harmful bacteria. Additionally, it modulated various metabolic pathways, promoted lamb growth, improved immunity, reduced the risk of gastrointestinal disease and improved the composition of gastrointestinal microbiota. In summary, our findings highlight the potential of SS treatment in enhancing gastrointestinal health of sheep lambs by improving intestinal function, immunity, and gut microbiome. Consequently, these results suggest that Fisch polysaccharides derived from Shanshan regions holds promising potential as a valuable intervention for optimizing growth performance in sheep lambs.

Introduction: We previously demonstrated efficacy of an 8-antigen recombinant subunit vaccine against a single species homologous challenge in lambs and in lambing ewes in pen trials. We subsequently demonstrated efficacy of a simplified, 2-antigen, version of this vaccine in lambs in pen trials. Here, we test both vaccines in lambing ewes in a field setting.

Background: Implant fixation is often the cornerstone of musculoskeletal surgical procedures performed to provide bony fixation and/or fusion. The aim of this study was to evaluate how different design features and manufacturing methods influence implant osseointegration and mechanical properties associated with fixation in a standardized model in cancellous bone of adult sheep.
Methods: We evaluated the performance of three titanium alloy implants: (A) iFuse-TORQ implant; (B) Fenestrated Sacroiliac Device; and (C) Standard Cancellous Bone Screw in the cancellous bone of the distal femur and proximal tibia in 8 sheep.

Tibetan sheep play a vital role in the livelihoods of herders and are an important part of the ecosystem of the Tibetan Plateau. In order to study the characteristics of the gut microorganisms of Tibetan sheep at high altitude, this study employed macrogenomic techniques to analyse the diversity and differences in the gut flora of Tibetan sheep in different regions of high altitude and high cold. The results demonstrated that at the phylum level, the dominant phylum in the ileo-cecum segment of Tibetan sheep in Qilian, Henan and Gonghe counties was identical, namely , and .

Introduction: The increase of antimicrobial resistance (AMR) in zoonotic pathogens poses a substantial threat to both animal production and human health. Although large-scale animal farms are acknowledged as major reservoirs for AMR, there is a notable knowledge gap concerning AMR in small-scale farms. This study seeks to address this gap by collecting and analyzing 137 fecal samples from goat and sheep farms in Tennessee and Georgia.

The aim of this study was to examine the antioxidant and immunomodulatory activities of ethanol extracts from (EESC) and (EEPC). Reflux extraction was carried out using 96% ethanol on the collected plant specimens to produce EESC and EEPC.
