Article Synopsis
- Dairy cattle breeds face recurrent recessive genetic defects that are often undetected due to conventional observation techniques missing various conditions, particularly those without clear symptoms.
- A new data mining framework has been developed to identify these hidden recessive defects in livestock by analyzing genomic data and comparing homozygote numbers in cattle with diverse life histories.
- This research uncovered 33 new genetic loci linked to increased juvenile mortality, offering insights into the genetic causes of inbreeding depression, which can enhance animal welfare and reduce industry losses.
Mastitis is a major issue for the dairy industry. Despite multiple attempts, the efficacy of available mastitis vaccines is limited and this has been attributed to their incapacity to trigger robust cell-mediated immunity. Yeasts have recently been identified as promising antigen vectors capable of inducing T-cell responses, surpassing the antibody-biased mechanisms elicited by conventional adjuvanted vaccines.

- - The study assessed the feasibility and safety of a new cancer treatment method called whole-body hyperthermia pressurized intraperitoneal aerosol chemotherapy (WBH-PIPAC) in patients with peritoneal surface malignancies.
- - Researchers reviewed data from 28 patients who underwent one cycle of traditional PIPAC before receiving multiple WBH-PIPAC treatments, finding no significant side effects from the hyperthermia process.
- - Results showed that while there were minor postoperative complications in some patients, the overall safety and effectiveness of WBH-PIPAC were similar to that of conventional PIPAC treatments.
The environmental impact of dairy production can be reduced in several ways, including increasing feed efficiency and reducing methane (CH) emissions. There is no consensus on their relationship. This study aimed at estimating the correlations between residual feed intake (RFI) and CH emissions expressed in g/d methane production (MeP), g/kg of fat- and protein-corrected milk methane intensity (MeI), or g/kg of DM intake methane yield (MeY) throughout lactation.

In the present study, we used dairy cows with different scores of susceptibility to mastitis with the aim to explore the relationships between microbiota composition and different factors in various body sites throughout lactation as well as the intra- and inter-animal microbial sharing.
Results: Microbiotas from the mouth, nose, vagina and milk of 45 lactating dairy cows were characterized by metataxonomics at four time points during the first lactation, from 1-week pre-partum to 7 months post-partum.
