Resveratrol is a natural polyphenolic compound that may have multiple influences on human health, including antiaging, anti-inflammatory, anti-neoplastic, antioxidant, insulin-sensitizing, cardioprotective and vasodilating activities. Growing evidence also suggests a potential positive effect of resveratrol on female fertility. The aim of the present study was to collate and appraise the scientific literature on the relationship between resveratrol and female fertility.

This study aimed to evaluate the effects of commercial vaccines on the control of porcine circovirus type 2 (PCV2), (Mhp), and (. ) and their potential side effects on welfare, behavior, acute inflammation biomarkers (C-reactive protein and haptoglobin), and the performance of piglets during the nursery phase.

- The study investigated how yeast cell wall prebiotics and probiotics affect gut health, immune response, and growth in weaned piglets as alternatives to antibiotic growth promoters.
- Results showed that the feed conversion ratio (FCR) was significantly better in piglets on the yeast treatments compared to those receiving antibiotics, with the best performers being those on the yeast cell wall diet alone.
- The introduction of probiotics appeared to enhance levels of certain immune markers, while also altering gut microbiota composition, particularly increasing the presence of beneficial Lactobacillus species in the probiotic groups.
Article Synopsis
- * Three piglets, aged 20-35 days old, were examined post-mortem after showing signs of neurological disease, leading to the identification of significant damage in the grey matter of their spinal cords and brainstems.
- * This marks the first documented case of PAstV3 in piglets with neurological disorders in Brazil, emphasizing the need for continued monitoring of health issues that could affect pig farming efficiency and animal welfare.
Objective: The objective of this study was to evaluate the use of condensed tannin from black acacia (Acacia mearnsii) as a substitute additive for zinc oxide and growth-promoting antibiotics on the performance, digestibility, and intestinal health of piglets in the nursery phase.
Methods: A total of 200 PIC piglets that were 22 days old and weighed 6.0±0.
