A new combination of a prebiotic and postbiotic mitigates immunosenescence in vaccinated healthy senior dogs.

Introduction: Elderly dogs often suffer from chronic diseases, in part attributed to immunosenescence, characterized by reduced blood CD4+ T cells (helper T cells) and elevation in the CD8+ T cells subset (cytotoxic T cells). Studies conducted in adult dogs suggested that supplementing short chain fructo-oligosaccharides (scFOS) or postbiotics derived from yeasts may positively influence the immune response. The aim of the current study was to investigate whether dietary supplementation with a combination of scFOS with a new yeast postbiotic (Profeed ADVANCED called scFOS+) could have a positive influence on the immune status of senior dogs subjected to an immune challenge (Lyme disease vaccination).

Survey of Belgian owners' perspectives on quality of life and difficulties during a weight-loss programme in obese cats.

Objectives: The aims of this study were to determine owners' perception of their cats' quality of life (QoL), and whether there is a correlation with weight-loss variables, as well as to identify the main difficulties owners encounter during controlled weight loss in their obese cats.

Methods: The study was carried out as an e-questionnaire survey addressed to owners of cats starting a weight-loss programme. The e-questionnaire was provided at a single time point after the conclusion of the study (24 weeks).

Evaluation of equine rectal inoculum as representative of the microbial activities within the horse hindgut using a fully automated in vitro gas production technique system.

The in vitro gas production technique (IVGPT) has been a valuable tool in ruminant nutrition research for decades and has more recently been used in horse nutrition studies to investigate fermentation activities of the equine hindgut though primarily using feces as inoculum. This study was conducted to evaluate the use of equine rectal content in the IVGPT system as a viable inoculum that can be considered representative of the activities throughout the equine hindgut. Additionally, the study was conducted to measure the effects on fermentation kinetics and end-product production using inoculum from horses fed supplemental levels of coated sodium butyrate in an IVGPT system.

High intake of sugars and starch, low number of meals and low roughage intake are associated with Equine Gastric Ulcer Syndrome in a Belgian cohort.

Equine gastric ulcer syndrome (EGUS) is a pathological condition affecting the glandular and squamous regions of the stomach. It is characterized by non-specific clinical signs, behavioural changes or can also be found without any overt clinical manifestations. Nutritional factors such as intermittent feeding, high sugars and starch intake, large amounts of straw as forage and prolonged time without access to forage have all been associated with an increased risk of equine squamous gastric disease (ESGD).

Effect of environmental factors and changes in the body condition score on the onset of the breeding season in mares.

Several methods have been proposed to advance the onset of the breeding season in horses. Most of them are based on the exposure to an artificial lighting period combined with hormonal treatments. Mares exposed to an artificial photoperiod are most often housed indoors where the ambient temperature is often higher than the outside temperature.

Fermentable soluble fibres spare amino acids in healthy dogs fed a low-protein diet.

Background: Research in cats has shown that increased fermentation-derived propionic acid and its metabolites can be used as alternative substrates for gluconeogenesis, thus sparing amino acids for other purposes. This amino acid sparing effect could be of particular interest in patients with kidney or liver disease, where this could reduce the kidneys'/liver's burden of N-waste removal. Since dogs are known to have a different metabolism than the obligatory carnivorous cat, the main objective of this study was to assess the possibility of altering amino acid metabolism through intestinal fermentation in healthy dogs.
