The Influence Of Diets Containing Phenols And Condensed Tannins On Protein Picture, Clinical Profile And Rumen Characteristics In Omani Sheep, Osman Mahgoub, Isam T.Kadim, Hamza A. Babiker, Mohammed N. Al-Kindi

Sultan Qaboos University Journal For Science

A study was carried out to investigate the effects of feeding low quality non-conventional feeds (NCF) containing phenols and condensed tannins on health and performance characteristics in Omani sheep. Twelve Omani sheep were fed one of two base roughages, urea-treated palm frond (UTPF) or Rhodesgrass hay, (RGH) plus a commercial concentrate for 63 days. Haematological, serum biochemical and urine analyses were used to assess sheep health. Serum protein fractions were measured using electrophoresis. Urea-treated palm frond contained higher levels of polyphenols and condensed tannins and fiber than Rhodesgrass hay or concentrate feed. Animals fed UTPF had lower feed intake (P<0.05) and lower body gain (P<0.001) than those fed RGH. Rumen liquor of UTPF-fed animals had higher pH, ammonia-nitrogen and butyric fatty acid but lower acetic fatty acid (P<0.05). Animals fed UTPF had higher neutrophil (P<0.05) but lower lymphocyte (P<0.05) and monocyte (P<0.001) counts by the end of the trial than those fed RGH. There were no effects of diet on serum albumin or globulin fraction levels or albumin:globulin ratio. There were no major effects on urine analysis but there was a trend by control animals to have higher protein and specific gravity than treated ones. This study indicated that feeding low quality non-conventional feeds containing polyphenols or tannins would reduce body gain and may produce some effects on clinical parameters. Although tannins are known to influence protein digestion and absorption in ruminants, it did not significantly affect the serum protein picture in sheep.

Metabolic And Microbial Crossroads: Sodium-Glucose Cotransporter-2 Inhibitors And Urinary Tract Infections In (Asian) Diabetes Care, Rob E. Carpenter Apr 2025

Metabolic And Microbial Crossroads: Sodium-Glucose Cotransporter-2 Inhibitors And Urinary Tract Infections In (Asian) Diabetes Care, Rob E. Carpenter

Human Resource Development Faculty Publications and Presentations

The global rise of type 2 diabetes, particularly in Asian populations, has led to widespread adoption of sodium-glucose cotransporter-2 (SGLT2) inhibitors for glycemic control. While effective, these agents elevate the risk of urinary tract infections (UTIs) by inducing glycosuria, which creates a nutrient-rich environment that favors uropathogen growth. Asian individuals may be disproportionately vulnerable to SGLT2 inhibitor–associated UTIs due to a confluence of factors, including lower body mass index, increased visceral adiposity, congenital urinary tract anomalies, and genetic polymorphisms that impair uroepithelial integrity and immunity. This review integrates emerging evidence on the molecular, anatomical, and immunometabolic mechanisms that underlie infection …

Covid-19 Persists: A Case Report, Benjamin Warren, Eugene Villa, Jhazmin Griffith

Advocate GME

Introduction: Coronavirus-19-Disease (COVID-19) gripped the world starting in 2019. New vaccines, regulations, and mandates have been implemented, and the virus itself continues to be studied. A fearful comorbidity that often leads to mortality is the hypercoagulable state COVID-19 induces. According to the American Society of Hematology, patients with COVID-19 are at increased risk of thrombotic complications, despite the in-hospital use of standard- or escalated-dose thromboprophylaxis [1]. While critical illness is known to cause a hypercoagulable state due to immobilization, mechanical ventilation, central venous access devices, and nutritional deficiencies, COVID-19 appears to cause a hypercoagulable state through mechanisms unique to SARS-CoV-2 …

Intra-Seasonal Shifts In Summer Elk Diet Composition, Ava E. Window Apr 2025

Intra-Seasonal Shifts In Summer Elk Diet Composition, Ava E. Window

University of Montana Conference on Undergraduate Research (UMCUR)

Elk (Cervus canadensis) require adequate forage to fulfill their seasonal nutritional requirements. Elk undergo their highest nutritional demands during summer to support critical life functions such as late gestation, lactation, and juvenile growth. During this period, variations in plant phenology significantly influence the quality and quantity of forage on the landscape. Recent literature has concentrated on late summer due to it's limiting nature. Yet, growing evidence suggests that both early and late summer forage often fail to meet the nutritional demands of lactating and reproducing female elk. Further, there is limited knowledge surrounding the intra-seasonal dynamics of elk …

Cervid Breakage Patterns In Western Montana, Tanner D. Liermann Apr 2025

Cervid Breakage Patterns In Western Montana, Tanner D. Liermann

University of Montana Conference on Undergraduate Research (UMCUR)

Sexual weapons are expected to withstand intense combat as weapon failure can directly impact an individual's reproductive success. Most weapons are permanent and a broken weapon costs that animal for the rest of its life. However, a few species regrow their weapons. The consequences of structural failure are lower in these animals, and they may invest less in their production as a result—leading to increased rates of breakage in the wild. Cervids (true deer) regenerate antlers each year, yet their rates of weapon failure remain unclear. In our study, we recorded breakage rates, antler point symmetry, harvest location, and age …
