Summary: Organic milk generally had higher levels of major nutrients compared to conventional milk, but lower levels of trace elements. Seasonal variations were observed in all mineral concentrations. Dietary factors, such as intake of different types of feed, played a significant role in the differences in milk mineral concentrations between organic and conventional production systems.

Summary: This study investigated the effect of seaweed supplementation in dairy cow diets on milk yield, basic composition, and mineral concentrations. The results showed minimal changes or concentrations in milk for Se, Cu, and As, which cannot be associated with any effects on consumer nutrition. Care should be taken when I-rich seaweed is fed to cows to avoid excessive animal I supply and milk I concentrations.

Summary: The study focused on developing a mechanistic model for dairy cows to analyze the yield gap in dairy production systems and evaluating the model performance. The newly adapted LiGAPS-Dairy model showed acceptable performance when applied to Holstein-Friesian cows under Dutch conditions, suggesting potential for further evaluation in other production systems, countries, and breeds for exploring options to increase resource use efficiency in dairy production.

Summary: Even minor iodine deficiency can have negative effects on thyroid health, while excess iodine intake can lead to thyroid disorders. Seaweed is a source of iodine that is gaining popularity as a food in Western countries. In addition to its role in thyroid health, gaseous iodine released from seaweeds plays a significant role in influencing coastal climate through cloud formation.

Summary: This study aimed to evaluate the effects of replacing inorganic trace minerals (STM) with organic trace minerals (OTM) on ovarian dynamics, estrous behavior, preimplantation conceptus development, and reproductive performance in dairy cows. The results showed that replacing STM with OTM resulted in modest improvements in ovarian cyclicity and conceptus development, but did not affect conception risk and pregnancy rate.

Summary: This study investigates dairy workers' attitudes towards euthanasia of dairy cattle and their association with demographic characteristics. The results show that some workers feel uncomfortable with euthanasia, while others feel confident and comfortable. White workers and caretakers with previous euthanasia experience are more likely to have positive attitudes towards euthanasia, while respondents who work on farms with 501-1000 cows are more likely to have negative attitudes towards euthanasia.

Summary: This study aimed to describe the management practices and perceptions of diseases in organic dairy cattle farmers in California. The results showed that farmers were concerned about mastitis in cows, pinkeye in heifers, and digestive problems in calves. Despite vaccinating against Bovine Viral Diarrhea and Escherichia coli mastitis, farmers still reported frequent impacts of these diseases on their animals. Additionally, over half of the farmers did not consider gastrointestinal parasites or biting flies as a problem, and they did not observe signs of lice and mites.

Summary: This study presents an approach for integrated sustainability assessment through whole-farm modelling to identify factors and mechanisms for improving economic profitability, social well-being, and environmental impacts of dairy production systems. It aims to create an evaluation framework for quantitative analysis of sustainability indicators and test this method. Overall, the models integrated at least 40% of proposed indicators, with higher scores obtained for the environmental pillar, followed by economic and social pillars. The evaluation framework was found to be an effective tool for potential users to choose among whole-farm models depending on their needs, and pathways for further model development towards more detailed sustainability assessment were identified.

Summary: This work reviews research on antibiotic residues and evaluates their use in livestock production, excretion in animal products, and environmental contamination worldwide. The main antibiotics used in animal production are sulfonamides, tetracyclines, quinolones, penicillin, and cephalosporins. Despite increasing regulations, antibiotics are still widely used and misused in many countries, posing a global contamination issue that requires improved control and reduction measures.

Summary: The objective of this study was to determine the trace element composition and the toxic metal residues in Galician cow's milk cheese produced in different systems (artisan, industrial, and organic). The results showed that the toxic elements were present at low concentrations, similar to those reported for other unpolluted geographical areas. The essential elements were also within the normal range in cheeses. There were no statistically significant differences between smoked and unsmoked cheeses for any of the elements. Chemometric analyses revealed that the industrial cheeses produced in Galicia using the milk from intensive dairy farms were different, in terms of elemental content, from artisan and organic cheeses, in which the elemental contents were similar.

Summary: This study analyzed the fatty acid composition of cow's milk in relation to the type of ration, parity, lactation phase, and season. The composition of milk fatty acids varies significantly based on these factors. The study highlights the importance of understanding the factors that affect the variation in fatty acid profile, as it is associated with animal health, organoleptic properties of milk, and even methane production.

Summary: This study investigated the levels of toxic and essential elements in raw milk produced in the State of Pernambuco, Brazil. The results showed that a high percentage of the samples had Pb levels above the tolerance limit established by Brazilian legislation, and the proximity of the farms to major roads is the main cause. Therefore, consuming milk produced under these conditions can be considered a risk to public health.

Summary: The study investigated the feasibility of using macroalgae as feed for rabbits and conducted research on the chemical composition, digestibility, and antimicrobial activity of different types of macroalgae. The results showed that macroalgae have the potential to be a prebiotic, which may have positive effects on the gut health of rabbits. However, further validation is required in practical applications.

Summary: Appropriate trace mineral supplementation, particularly zinc, is crucial for enhancing the metabolic status of growing animals. This study analyzed the effects of zinc supplementation on growth parameters in small ruminants through meta-analysis, finding that zinc supplementation led to increased dry-matter intake, average daily gain, and improved feed efficiency. Various factors such as species, breed, production level, zinc source, and dosage influenced the level of response in growth performance.
