The retention of protein, fat and energy of Palatinit was measured in a trial with carcass analyses and compared with that of sucrose. Therefore 39 male rats weighing about 200 g were divided in three groups. In order to get basic values, 4 animals of each group were slaughtered. The other 3 X 9 animals were fed 56 days in one group the basal diet, in two other groups the same diet plus sucrose and Palatinit, respectively. The retention of dry matter, protein, fat and energy was calculated with carcass analyses. The results show that the supplement of Palatinit gave higher values of retention compared with the basal diet, but there was no change in the body composition. Compared with this, the supplement of sucrose brought not only higher values of retention, but also a changed carcass composition compared with the basal diet and the supplement of Palatinit, too; thereby the fat content was significantly higher, and the protein content was lower. The retention of energy was reduced by 33% with the supplement of Palatinit, compared with the isocaloric supplement of sucrose.

Quercetin Supplementation Reduces Oxidative Stress in the Testes of Wistar Rats Fed a High-Fat Diet.
Am J Reprod Immunol

Problem: A high-fat diet (HFD) predisposes animals to glucose intolerance, dyslipidemia and testicular oxidative stress, and impairs sperm production in rats. Quercetin is a flavonoid with antioxidant, anti-inflammatory, and lipolytic actions and is a potential supplement to combat the oxidative stress caused by HFD and its harmful effects on reproduction. This study evaluated the effects of quercetin supplementation at doses of 10 and 20 mg/day on reproductive parameters and testicular oxidative stress in Wistar rats fed a diet rich in pork fat and fructose.

The aim of this experiment was to investigate the effects of intravenous infusion of lipopolysaccharide (LPS) and feeding different ratios of lysine (Lys) and methionine (Met) on feed intake, apparent digestibility, rumen fermentation and microorganisms in young Holstein bulls. Five seven-month-old Holstein bulls with similar body weights (279 ± 42 kg) were selected and subjected to a 5 × 5 Latin square experiment. The control group (CON) was fed with basal diet and the ratio of Lys to Met in the diet was adjusted to 3.

Post-streptococcal autoimmune neuropsychiatric disorders (PANDAS) are a group of pathological condition characterized by sudden-onset obsessive-compulsive and tic disorders following beta-hemolytic Streptococcus group A (GAS) infection, hypothesized to be caused by autoimmune mechanisms targeting the basal ganglia. Scant literature is available regarding the microbiota composition in children with PANDAS, however few studies support the hypothesis that streptococcal infections may alter gut microbiota composition in these patients, leading to chronic inflammation that may impact the brain function and behavior. Notable changes include reduced microbial diversity and shifts in bacterial populations, which affect metabolic functions crucial for neuroinflammation.

Zymdetox Z-2000 is a novel zearalenone (ZEN) lactonase produced by Bacillus subtilis that can biodegrade ZEN to hydrolyzed ZEN and decarboxylated hydrolyzed ZEN with much lower estrogenic activity. This study aims to evaluate the efficacy of Zymdetox Z-2000 in mitigating the adverse effects of ZEN on the growth performance and reproductive health of gilts. A total of 80 crossbred Landrace × Yorkshire gilts (9.
