Ruminants serve a valuable role in sustainable agricultural systems, specifically in the conversion of renewable resources from grasslands, pasture, and other by-products into high-quality human food. Recognizing forage and grasses are grown on 25% of arable land, suitable agronomic practices for management of grazing livestock are necessary for the economic sustainability of the livestock enterprise, whereas at the same time, minimizing water and soil erosion. Demographics of undergraduate animal science students have changed over the last several years with more students from urban backgrounds and with interests other than traditional animal agriculture. Thus, continued emphasis on education programs supporting grazing livestock industries becomes that much more important. In addition, newer technologies to measure production on range and pastureland have emerged, thereby increasing opportunities for further training and education. Based on an email assessment of 10 land grant institutions, typically one MS student/yr and one PhD student/3 to 4 yr graduates with an advanced degree in forage agronomy. Overall budget reductions which impact operational costs, internal funding for research projects and graduate student stipends, force universities to focus in areas with the best chance of monetary return. Challenges with funding faculty positions outside of a department's emphasis area typically result in the question "Should forage agronomy students be trained in Departments of Animal Science or Agronomy/Plant/Soils Sciences?" It could be argued that either department is the best fit. Forage agronomy requires training in the basics of plant and soil science, but the application of those sciences within a Department of Animal Science relates more to animal science/production than to traditional crop production such as cereal grains. Animal science departments must communicate the meaningful context of forage agronomy in an active learning environment developing students' ability to critically think and solve problems. Those providing technical expertise to livestock producers can no longer make recommendations based solely on production efficiency and profitability. Instead, best management practices must include the impact of grazing livestock on the environment and environmental sustainability. Cooperative agreements between departments should be discussed to adequately support student development in this critical subject matter.

Sericulture waste poses significant challenges to industrial and environmental safety. Black soldier fly larvae (BSFL) offer a promising solution for organic waste management by converting it into insect protein. This study aimed to develop a microbial fermented method for utilizing sericulture waste to feed BSFL and explore the underlying mechanisms.

The glucocorticoid receptor (GR) is present in almost every vertebrate cell and is utilized in many biological processes. Despite an abundance of mammalian data, the structural conservation of the receptor and cross-species susceptibility, particularly for aquatic species, has not been well defined. Efforts to reduce, refine, and/or replace animal testing have increased, driving the impetus to advance development of new approach methodologies (NAMs).

Lumpy skin disease (LSD) is an emerging, highly contagious transboundary disease of bovines caused by the Lumpy skin disease virus (LSDV), responsible for substantial economic losses to the dairy, meat, and leather industries in Pakistan as well as various countries around the world. Epidemiological information on LSD is scarce in Punjab, Pakistan. Therefore, a molecular epidemiological study was conducted in two agro-ecologically diverse districts (Bhakkar and Jhang) of Punjab, Pakistan.

Nucleus pulposus cell (NPC) senescence contributes to intervertebral disc degeneration (IVDD). However, the underlying molecular mechanisms are not fully understood. In this study, it is demonstrated that angiotensin-converting enzyme 2 (ACE2) counteracted the aging of NPCs and IVDD at the cellular and physiological levels.

Placental malaria is characterized by the massive accumulation and sequestration of infected erythrocytes in the placental intervillous blood spaces, causing severe birth outcomes. The variant surface antigen VAR2CSA is associated with Plasmodium falciparum sequestration in the placenta via its capacity to adhere to chondroitin sulfate A. We have previously shown that the extracellular region of VAR2CSA is phosphorylated on several residues and that the phosphorylation enhances the adhesive properties of CSA-binding infected erythrocytes.
