The increasing demand for natural alternatives to chemical preservatives and antibiotics has intensified interest in probiotic microorganisms with intrinsic antimicrobial properties. Lactiplantibacillus plantarum, a well-characterised species within the family Lactobacillaceae, is widely recognised for its broad‑spectrum antibacterial activity and its long history of safe use in fermented foods. This review provides a comprehensive synthesis of recent advances in the antimicrobial functionality of L. plantarum, covering its taxonomic classification, genomic features, and the diverse array of antimicrobial metabolites...

Testicular blood flow and haemodynamics play a critical role in maintaining spermatogenesis and thermoregulation in bulls. The assessment of the testicular blood flow provides detailed insights into the reproductive function in male animals. This study aimed to characterise the testicular perfusion pattern using pulse wave Doppler ultrasonography in the Shweta Kapila breed of indigenous cattle reared in their native habitat on the Indian west coast. Healthy Shweta Kapila bulls (n = 8) maintained under semi-intensive systems were examined. A digital Pulse Wave Doppler ultrasound system equipped with a linear array probe was used to assess...

This study aimed to investigate the effects of drinking water temperature on growth performance and gastrointestinal microbiota in growing calves. Forty-five weaned male calves were randomly divided into three treatment groups (n = 15 per group). The groups were provided with drinking water at different temperatures: 5–10 °C (FC), 20–25 °C (FM), or 35–40 °C (FW). The experiment lasted for 30 days, during which all calves were housed in individual hutches. Body weight and jugular blood samples were collected on days 0, 15, and 30; body measurements were taken on days 0 and 30. On day 30, rumen fluid and faecal...

Effects of dietary inclusion of condensed tannins from Schinopsis lorentzii and age on the physicochemical properties, and the content of minerals and amino acids content of meat in Eimeria-challenged broilersOriginal Paper

The aim of the study was to evaluate the dietary effect of condensed tannins (CT) from red quebracho (Schinopsis lorentzii) and broiler age on the physicochemical properties, mineral composition, and amino acid content in the meat of broilers challenged with Eimeria spp. Broilers were randomly assigned to four dietary groups: CT1 and CT2 received 10 and 20 g CT/kg, respectively; the control (C) group received a basal diet; and the R group received a basal diet with a coccidiostat. Meat quality indicators were assessed at 35 and 42 days of age. Supplementation with the higher CT level (2%) reduced carcass weight, particularly at...
