TL;DR: In conclusion, lying behavior is important to dairy cattle, but caution and a full understanding of the context and the character of the animals in question is needed before drawing firm conclusions about animal welfare from measures of lying time.

TL;DR: In this article, the authors argue that changes in circulating NEFA, ketones, and calcium are simply reflective of normal homeorhetic adjustments that healthy, high-producing cows use to prioritize milk synthesis or the consequence of immune activation and its sequelae.

TL;DR: Global regulatory frameworks for probiotic yogurt and prebiotic and nonprebiotic ingredients included in yogurt are reviewed and the need for convincing clinical trial outcomes that provide the dairy industry with an opportunity to market products with substantiated beneficial claims is emphasized.

TL;DR: The application of micellar casein concentrates in protein standardization could offer a window of opportunity to US cheese makers by improving yields and throughputs in manufacturing plants as mentioned in this paper.

TL;DR: The potential applications of acid whey, such as its use as a starting material in the production of fermented beverages, as growth medium for cultivation of lactic acid bacteria in replacement of commercial media, and as a substrate for the isolation of lactose and minerals, are reviewed in this article.

TL;DR: Asparagopsis taxiformis (AT) is a source of multiple halogenated compounds and, in a limited number of studies, has been shown to decrease enteric CH4 emission in vitro and in vivo as discussed by the authors.

TL;DR: This is the first study that reports novel AG and AAM inhibitory peptides from camel whey proteins, and these peptides were identified as potential inhibitors for both AAM and AG due to their high number of binding sites and highest binding probability toward the target enzymes.

TL;DR: In this paper, the effects of camel whey proteins (CWP) and their hydrolysates (CWPH) on the activities of dipeptidyl peptidase IV (DPP-IV) and the human insulin receptor (hIR) were reported.

TL;DR: In this article, the authors compare the performance of dairy and beef matings and find that dairy females exhibit greater genetic variability than beef females, which implies that "one size fits all" may not be appropriate for bull selection.

TL;DR: In this paper, the effects of sheep milk ice cream [conventional full-fat (CONV), full fat enriched with probiotic (PROB, 100 mg % wt/wt of Lacticaseibacillus casei 01), or nonfat synbiotic (SYNB, Lacticasesibacilli casei01 and inulin, 10% wt /wt)] on carcinogen-induced colonic crypt cytotoxicity and premalignant lesion development were evaluated.

TL;DR: There is a need for clear and independently accredited grass-fed standards, defining the grass- fed criteria for labeling of products as such, subsequently increasing the clarity and confidence for the consumer.

TL;DR: The targeted manipulation of the BMB permeability may be a tool to optimize the immune function of the mammary gland and increase the contribution of the specific immune system in the immune defense.

TL;DR: PDT have great potential for application in dairy calf management, enabling precise behavioral and physiological monitoring, targeted feeding programs, and identification of calves with poor health or behavioral impairments.

TL;DR: In this article, the authors evaluated the expected response of economically important traits by including CH4 traits in the breeding goal, as residual methane allows for selection of low methane emitting animals without compromising other economically important attributes.

TL;DR: In this paper, the authors used a Markov chain Monte Carlo approach to estimate the annual losses per cow within MAP-infected herds and the total regional losses due to Johne's disease.

TL;DR: In this article, the authors reviewed and discussed the recent approaches, methods used for the selection, and outcomes of the evaluation of novel probiotic strains with the main purpose of supporting future probiotic microbial assessment studies.

TL;DR: This review will address the primary microbial causes of premature dairy product spoilage and methods of controlling this spoilage to reduce loss and waste in dairy products.

TL;DR: It is indicated that CMPH can be suggested for its therapeutic benefits for hyperglycemia and hyperlipidemia, thus validating its use for better management of diabetes and associated comorbidities.

TL;DR: In this article, the authors compared the metabolic status and mitochondrial function in mammary tissues harvested by biopsy from healthy and clinically ketotic cows within 2 to 3 wk postpartum.

TL;DR: The research reflects the performance implications of mastitis, providing more information upon which the producer can make informed culling decisions and maximize both herd profitability and cow longevity.

TL;DR: The results suggest that direct selection for a residual methane production trait would result in indirect, favorable improvement in all other methane traits, and highlight the importance of expanding data sets by measuring more animals for their methane emissions and DMI, or through exploration of proxies and combining data via international collaboration.

TL;DR: In this paper, the authors developed a high-throughput gas chromatography-mass spectrometry method to determinate milk FA, and the proposed method had satisfactory linearity, sensitivity, accuracy, and precision.

TL;DR: A review of past and current research on mastitis vaccines reveals the peculiarities but also the commonalities among mammary gland infections associated with the major mastitis pathogens, such as Escherichia coli, Staphylococcus aureus, Streptococcus uberis, or Staphococcus agalactiae.

TL;DR: The study demonstrated that facilitation has a valuable role to play in participatory approaches beyond moderating discussion; facilitators encouraged knowledge mobilization within the groups and were participants in the research as well.

TL;DR: The use of antimicrobials in animal agriculture is under increasing scrutiny, but the quantity of antimicrobial usage used on large US dairy farms has not been evaluated using data from large farms and different metrics as discussed by the authors.

TL;DR: In this paper, the antihypercholesterolemic bioactive peptides derived from peptic camel whey protein hydrolysates (CWPH) were generated at different time, temperature, and enzyme concentration.

TL;DR: This article conducted a systematic review to assess the evidence and knowledge gaps in the published literature and identified the main recommendations to effectively overcome barriers, elicit appropriate behavior change, and achieve reduced antimicrobial use in dairy cattle.

TL;DR: The insights gained from these results could aid dairy producers to detect heat stress before it becomes severe, which could decrease the negative effects of heat stress, such as milk loss.

TL;DR: In this article, the use of statistical machine learning methods for trait prediction from mid-infrared spectroscopy may improve the prediction accuracy for some traits, such as curd firmness, pH, and micelle size.

TL;DR: Insight is provided into the coagulation kinetics of goat and sheep skim milk under in vitro gastric digestion conditions and the pattern of protein hydrolysis by pepsin was similar for the milk of all species, despite the differences in the proportions of different proteins.
