Simple Summary: The application of chelated trace minerals (CTM) in livestock nutrition is an expanding research area with a focus on the health and quality of animal products. The aim of the current study was to conduct a scientometric analysis of the last three decades on CTM application in animal nutrition to point out main sources, most prolific countries, and current and emerging topics. This investigation is descriptive in terms of type and practical in purpose. The findings showed that the words zinc, copper, performance, pig, cattle, metabolism, and bioavailability were prominent words reflecting the hotspots in the chelate field during the investigated time period. The frequencies of the terms health, muscle, bovine, trace elements, and dietary supplements indicate that they are emerging topics in CTM as research has begun to focus on these areas. The purpose of this study was to look at research trends in the application of CTM in animal nutrition in order to identify current and emerging challenges, as well as to examine the intellectual structure of the subject. The intellectual structure of CTM was examined using keyword and reference analysis. The research community includes all research and review articles published in journals indexed in the Web of Science database during the years 1990–2022. The results showed that the terms zinc, co-occurring 331 times, performance (324 times), and copper 216 (times) were the main and hotspots of research in the field of chelate. The data suggest that the most important keywords during the study period were zinc, copper, pig, bovine, metabolism, and bioavailability. The terms health, muscle, beef, trace elements, and dietary supplements represent emerging topics in CTM, as research began to focus on these areas during the years 2017–2022. The country with the greatest number of published articles was the United States of America. This bibliometric analysis showed that countries are focusing on the effects of CTM on the health and musculature of cattle through dietary supplementation with trace elements. According to the identified hot and emerging topics, this research can serve as a roadmap for a global comprehensive scientific plan and policy. [ABSTRACT FROM AUTHOR]

Simple Summary: The field of animal welfare science studies the well-being of animals, including an animal's physical and emotional state. Previous studies have investigated veterinary students' perceptions of animal welfare, although few studies have focused on animal science students' perceptions of the topic. The aim of this study was to determine if animal science students' perceptions of animal welfare differed across a multitude of animal categories, including agricultural animals, cats and dogs, horses and other equids, research animals, and wildlife. Results indicate that most survey respondents agreed that animal welfare was important for all animal categories. In qualitative analyses of the open-ended survey questions, basic needs and human interaction were identified by respondents as key welfare components for all animal categories; however, the frequency with which identified welfare themes was mentioned differed by category. Results also highlighted perception differences within different agricultural animal species; fewer respondents agreed that poultry and swine are raised with an appropriate level of welfare compared to dairy and beef cattle. Understanding animal science students' perceptions of animal welfare may lead to a greater understanding of how they will assess and manage animal welfare issues as part of their future careers in the agricultural and animal-related sectors. Animal welfare is an increasingly important topic across multiple academic disciplines; however, few studies have investigated student perceptions of animal welfare outside of veterinary medicine. The objective of the study was to evaluate animal science students' perceptions of animal welfare to determine if perceptions differ across animal categories. An online survey was distributed to animal science programs at institutions across the United States. Quantitative and qualitative analyses were performed on 624 responses. Almost all respondents agreed welfare was important for all animal categories (≥97%). The survey asked respondents to rate the level of importance of 12 welfare parameters and there was evidence that the level of importance differed by animal category (p < 0.0001), e.g., fewer respondents indicated having positive interactions with humans was important for agricultural animals. In a subset of questions about agricultural animals, fewer respondents agreed that swine (325, 52.1%) and poultry (268, 43.0%) are raised with an appropriate level of welfare compared to dairy (425, 68.1%) and beef cattle (421, 67.5%). Four free-response questions asked respondents to report their general perceptions of welfare. Thematic analysis identified multiple themes, such as basic needs and human interaction, with most responses (75%) including two or more themes. [ABSTRACT FROM AUTHOR]
