Effect of temperature-humidity index on the evolution of trade-offs between fertility and production in dairy cattle
CONCLUSIONS: Within the range of weather conditions studied, increasing temperatures are not expected to exacerbate the fertility-production trade-off. However, our results indicated that the animals with the best breeding values for production today will be the most affected by temperature increases, both in terms of fertility and production. Nonetheless, these animals should remain among the most productive ones during heat waves. For Montbeliarde, the current selection program for fertility seems to be adequate for ensuring the adaptation of fertility traits to temperature increases, without adverse effects on productio...

Molecules, Vol. 29, Pages 1552: Streptococcus thermophilus: A Source of Postbiotics Displaying Anti-Inflammatory Effects in THP 1 Macrophages
ent Miclo
In addition to traditional use in fermented dairy products, S. thermophilus also exhibits anti-inflammatory properties both in live and heat-inactivated form. Recent studies have highlighted that some hydrolysates from surface proteins of S. thermophilus could be responsible partially for overall anti-inflammatory activity of this bacterium. It was hypothesized that anti-inflammatory activity could also be attributed to peptides resulting from the digestion of intracellular proteins of S. thermophilus. Therefore, total intracellular proteins (TIP) from two phenotypically different strains, LMD-9 and CNRZ-21N,...

Genes, Vol. 15, Pages 439: Molecular Mechanisms Associated with the Development of the Metritis Complex in Dairy Cattle
ammed K. Abo-Ismail
The metritis complex (MC), a group of post-partum uterine diseases, is associated with increased treatment costs and reduced milk yield and fertility. The goal of this study was to identify genetic variants, genes, or genomic regions that modulate MC disease. A genome-wide association study was performed using a single-locus mixed linear model of 1967 genotypes (624,460 SNPs) and metritis complex records. Then, in-silico functional analyses were performed to detect biological mechanisms and pathways associated with the development of MC. The ATP8A2, COX16, AMN, and TRAF3 genes, located on chromosome...

Comparison of different organic selenium supplementations on selenium status and serum biomarkers in dairy cows
The objective of this study was to investigate the effects of two different organic selenium (Se) supplements, selenomethionine (Se-Met) and selenohomolanthionine (Se-Hlan), on the serum biochemical parameters and Se status of dairy cows. Different dietary Se supplementation treatments were set as follows: a control group (CON, adding sodium selenite at 0.3 mg Se/kg dry matter [DM]), 0.3 and 0.5 Se-Met (adding Se-Met at 0.3 and 0.5 mg Se/kg DM, respectively), as well as 0.3 and 0.5 Se-Hlan (adding Se-Hlan at 0.3 and 0.5 mg Se/kg DM, respectively). The experiment lasted 8 weeks. The serum measurements showed that both ...

Sensors, Vol. 24, Pages 2194: Research on the Vision-Based Dairy Cow Ear Tag Recognition Method

Jia Tian
With the increase in the scale of breeding at modern pastures, the management of dairy cows has become much more challenging, and individual recognition is the key to the implementation of precision farming. Based on the need for low-cost and accurate herd management and for non-stressful and non-invasive individual recognition, we propose a vision-based automatic recognition method for dairy cow ear tags. Firstly, for the detection of cow ear tags, the lightweight Small-YOLOV5s is proposed, and then a differentiable binarization network (DBNet) combined with a convolutional recurrent neural network (CRNN...

Rhein against < em > Staphylococcus xylosus < /em > by interfering with respiratory metabolism and inducing oxidative stress
In conclusion, rhein has good anti-S. xylosus effects in vitro and in vivo, by interfering with bacterial energy metabolism, inducing ROS production, and causing cell membrane and DNA damage, which may be one of the important mechanisms of its antimicrobial activity.PMID:38545378 | PMC:PMC10966458 | DOI:10.1016/j.crfs.2024.100718 (Source: Cell Research)

Method for evaluating milk production in mouse mammary gland
AbstractLactation is a characteristic physiological function of mammals and is important for nourishing infants and the dairy industry; however, the molecular mechanisms underlying the function remain to be elucidated. A technique to directly evaluate the quantity and quality of milk in mice is necessary for the study of the lactation mechanism in vivo. By measuring the changes in milk amount after different durations of milk accumulation (0 –24 h) using a ductal cannulation technique and oxytocin supplementation, we estimated the milk production rate at a single mammary gland level. In addition, collected milk was ava...

Screening for potential warning biomarkers in cows with ketosis based on host –microbiota co-metabolism analysis
ConclusionKetotic cows experienced bile acid metabolism disorders 7 days before calving, and the gut microbiota was closely related to bile acid metabolism disorders. Future studies should investigate the relationship between secondary bile acids and the development of ketosis. (Source: Frontiers in Microbiology)

The ‘Good Kiwi’ and the ‘Good Environmental Citizen’?: Dairy, national identity and complex consumption-related values in Aotearoa New Zealand
AbstractAlongside concerns for animal welfare, concerns for land, water, and climate are undermining established food identities in many parts of the world. In Aotearoa New Zealand, agrifood relations are bound tightly into national identities and the materialities of export dependence on dairying and agriculture more widely. Dairy/ing identities have been central to national development projects and the politics that underpin them for much of New Zealand’s history. They are central to an intransigent agrifood political ontology. For the last decade, however, they have been challenged by the identity politics of ethica...

Dietary Exposure and Risk Assessment of Multi-Mycotoxins (AFB1, AFM1, OTA, OTB, DON, T-2 and HT-2) in the Lebanese Food Basket Consumed by Adults: Findings from the Updated Lebanese National Consumption Survey through a Total Diet Study Approach
The objectives of the current study were to evaluate the dietary exposure of Lebanese adults to multi-mycotoxins (aflatoxin B1 (AFB1), aflatoxin M1 (AFM1), ochratoxin A (OTA), ochratoxin B (OTB), deoxynivalenol (DON), T-2 and HT-2) and to assess their associated health risks. Hence, a nationally representative sample of 449 participants aged 18-64 years old were interviewed to obtain their socio-demographic characteristics, food consumption data and exposure estimates. A food frequency questionnaire and 24 h-recall were used to collect data. The concentration of mycotoxins in all foods consumed by the participants was coll...
