Summary: Increasing milking frequency can boost milk yield, but different milking intervals did not significantly affect milk component yields. By using uneven milking intervals, labor efficiency can be improved while still optimizing milk production in early-lactation cows.

Summary: This research investigates the compensation mechanism of iodine deficiency and excess in the mammary gland during lactation. The study found that milk iodine concentration is positively correlated with iodine intake, and the regulation of glycosylation and degradation of NIS by DPAGT1 and VCP in the mammary gland plays a role in regulating milk iodine level. However, the mammary gland has limited ability to compensate for iodine deficiency and excess.

Summary: In this study, RNA-seq was used to analyze the mammary gland transcriptomes of high-yielding and low-yielding yaks during lactation. The results showed that 144 differential genes were identified, which were involved in various biological processes such as carbohydrate metabolism. This study provides new insights into the molecular mechanism of yak mammary gland tissue and potential strategies for improving milk production in yaks.

Summary: This study conducted transcriptome sequencing of goat-mammary-gland tissue at different developmental stages to reveal the expression characteristics and molecular functions of circRNAs during mammary involution. A total of 11,756 circRNAs were identified, with 2528 circRNAs expressed in all three stages. Gene ontology analysis showed functional diversity of circRNAs' source genes. Furthermore, differentially expressed circRNAs and circRNA-miRNA-mRNA ceRNA regulatory networks were identified, providing insights into the regulatory role of circRNAs in mammary cell involution and remodeling.

Summary: This study evaluated the transcriptome of mammary tissue in four yaks throughout the lactation cycle. The analysis identified over 6000 differentially expressed genes, with a large number of genes showing differential expression at the onset and end of lactation. The functions affected by transcriptomic adaptation to lactation in yak mammary tissue were similar to those observed in dairy cows, including induction of lipid metabolism, amino acid metabolism, and glycan biosynthesis, as well as suppression of the cell cycle and immune response.

Summary: Obesity is a modern pandemic that negatively impacts women's reproductive health. Women with obesity experience changes in their mammary glands which affect their ability to exclusively breastfeed. The hormone prolactin, which is responsible for lactation, has reduced activity in the mammary glands of obese lactating rodents, contributing to impaired lactation. Treatment with prolactin has shown to improve milk production in women with inadequate lactation. This review focuses on the effects of diet-induced obesity on lactating mammary glands and how obesity impairs the lactogenic action of prolactin. While the impact of obesity on lactation has been studied in both humans and rodents, most of the research has been conducted on rodents.

Summary: This experiment investigated the responses of late lactation dairy cows to a heat challenge when offered wheat-grain or corn-grain. Results showed that feeding corn grain during a heat challenge reduced some of the negative impacts of heat stress, enabling the cows to consume more forage compared with supplementing with wheat grain. The differences in ruminal fermentation of cereal grains can affect thermoregulation during heat stress.

Summary: The study showed that feeding frequencies did not affect the performance of male feedlot lambs, but feeding three or four times a day promoted higher digestibility of certain nutrients. The recommended feeding frequency for male feedlot lambs is once a day, as it does not compromise performance or meat quality.

Summary: The mammary gland undergoes significant anatomical and physiological changes from embryogenesis through various stages, with epigenetic mechanisms playing a crucial role in these processes. Research has shown the importance of epigenetic marks in milk component biosynthesis and highlights the involvement of DNA methylation, histone modifications, polycomb protein activity, and non-coding RNA functions in regulating gene expression in the mammary gland.

Summary: Enhanced post-ruminal supply of methionine can affect mammary metabolism and immune response. Heat stress and rumen-protected methionine have been found to influence abundance and phosphorylation of signaling proteins in mammary gland. However, rumen-protected methionine supplementation does not attenuate the inflammatory response induced by lipopolysaccharide in vitro.

Summary: Seasonal weight loss is a major issue in small ruminant production in drought-prone regions. This study aimed to evaluate the effect of seasonal weight loss on fatty acid profile in three different ovine breeds: Merino, Dorper, and Damara. Results showed variations in fatty acid mobilization from adipose tissue, with Dorper and Damara breeds exhibiting unique variations related to muscular tissue maintenance and hepatic adaptations respectively. Generally, Dorper and Damara breeds performed better under nutritional restriction.

Summary: This study aimed to investigate the effect of different dry-off strategies on blood metabolites, hormones, and minerals. It was found that reducing feeding level and milking frequency can decrease glucose and insulin concentrations while increasing free fatty acid concentrations in dairy cows. The injection of dopamine agonist cabergoline can reduce prolactin concentration and cause abnormal changes in plasma metabolites, hormones, and minerals.

Summary: This paper presents a bibliographic mapping analysis of publications in the journal Tropical Animal Health and Production (TAHP) using data from Scopus. The analysis provides valuable insights for self-evaluation, scope assessment, and future direction of the journal. The findings indicate improvements in metrics such as Article Influence, Percentage of papers in Open Access, Immediacy Index, and Journal Impact Factor. However, further enhancements are still needed. The journal plays a crucial role in advancing knowledge of animal health and production in tropical and sub-tropical regions.

Summary: This study evaluates the effects of seaweed diets on piglets' hematologic and serologic profiles, hepatic lipids, and minerals. The results show that seaweed supplementation can increase white blood cells and lymphocytes, boost IgG levels, stabilize glycemic homeostasis, and reduce serum lipids and cortisol levels. It also improves the composition of fatty acids in the liver. However, it has no significant effect on hepatic pigments. Seaweed diets have positive effects on piglets' growth and health.

Summary: Seaweeds, such as Laminaria digitata, are a sustainable alternative to conventional feedstuffs for weaned piglet diets, improving their health and mitigating environmental impacts. This study evaluated the impact of 10% L. digitata feed inclusion and carbohydrate-active enzymes (CAZymes) on piglet blood cells, serum metabolites, liver lipid profiles and mineral content. The results showed that L. digitata inclusion improved piglet immune response and cardiovascular health.

Summary: This study aimed to evaluate the influence of different production ecosystems (native pastures, cultivated pastures, and confinement) and seasons (dry and rainy) on the mineral content of buffalo liver in the Eastern Amazon. The results showed that the different ecosystems and seasons significantly affected the mineral content of buffalo liver, including sodium, potassium, calcium, and magnesium. Therefore, buffalo liver is a good source of minerals and the ecosystem in which the animals are raised has an impact on its content.

Summary: This study investigates the response of Majorera and Palmera dairy goat breeds to seasonal weight loss using different Omics tools. Unrestricted goats show higher protein synthesis and milk production, while restricted goats may adapt to nutritional limitations by fatty acid synthesis and energy utilization. Differential expression of certain genes may serve as potential biomarkers for SWL susceptibility.

Summary: This study aimed to characterize the colostrum quality in different goat breeds and found that there are differences in fat, total solids, lactose, and protein percentages among breeds. It was also found that IgG is the parameter that best differentiates local breeds from cosmopolitan ones. The differences in colostrum quality could be influenced by farming systems and genetic characteristics.
