Multiparameter growth-performance monitoring of Holstein dairy heifers fed on moderate- or high-energy feeding plans from birth to puberty.

Today, dairy cattle farmers are seeking to optimize expenditure and productivity throughout the lives of their animals by focusing on efficiency at all levels. One strategy for bringing forward the start of a dairy cow's profitability phase is to advance the onset of puberty and reduce the animal's age at their first calving. Thus, one objective of this study was to feed two groups of Holstein dairy heifers the same diet but in different quantities, with the aim of generating a growth differential of at least 200 g/day between the two groups.

Saccharomyces cerevisiae as a platform for vaccination against bovine mastitis.

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.

Figure of eight suture technique in aortic valve replacement decreases prosthesis-patient mismatch.

Background: While the pledget suture technique has been the standard for surgical aortic. valve replacement (AVR), discussion continues regarding the possibility of the nonpledget suture technique to produce superior structural and hemodynamic parameters. This study aims to assess the effectiveness of the figure-of-eight suture technique in AVR, as determined by the incidence of prosthesis-patient mismatch (PPM).

Effect of long-term cannabidiol on learning and anxiety in a female Alzheimer's disease mouse model.

Cannabidiol is a promising potential therapeutic for neurodegenerative diseases, including Alzheimer's disease (AD). Our laboratory has shown that oral CBD treatment prevents cognitive impairment in a male genetic mouse model of AD, the hemizygous () mouse. However, as sex differences are evident in clinical populations and in AD mouse models, we tested the preventive potential of CBD therapy in female mice.

Chronic dietary exposure to a glyphosate-based herbicide results in total or partial reversibility of plasma oxidative stress, cecal microbiota abundance and short-chain fatty acid composition in broiler hens.

Glyphosate-based herbicides (GBHs) are massively used in agriculture. However, few studies have investigated the effects of glyphosate-based herbicides on avian species although they are largely exposed via their food. Here, we investigated the potential reversibility of the effects of chronic dietary exposure to glyphosate-based herbicides in broiler hens.
