Two trials were conducted in which male turkeys from commercial Strains A and B were fed diets calculated to contain 80, 100, or 120% of recommended levels of protein from 1 to 8 wk of age and recommended levels of protein at other ages. Feeding reduced protein diets decreased 8-wk BW of both strains. No difference in BW, however, was evident at 17 wk in either strain. Dietary protein level generally did not influence overall feed to gain ratios, feed intake, or behaviors of male turkeys from these two strains. Effects of dietary protein level on walking ability were inconclusive. The results of the present study indicate that it may be possible to reduce early dietary protein levels with savings in feed cost for male turkeys with no adverse effects on growth or feed conversion at market age.

Background: Use of health applications (apps) to support healthy lifestyles has intensified. Different app features may support effectiveness, including gamification defined as the use of game elements in a non-game situation. Whether health apps with gamification can impact behaviour change and cardiometabolic risk factors remains unknown.

The beneficial effects of water-soluble dietary fiber on liver fat and fibrosis involve the gut microbiota; however, few epidemiological studies have investigated this association. This large-scale epidemiological study aimed to determine the effect of water-soluble dietary fiber intake on liver fat and fibrosis via gut microbiota for the general population. We divided low- and high-intake groups by median daily water-soluble dietary fiber intake and matched background factors by propensity score matching for sex and age.

The neuropeptide oxytocin (OXT) and its receptor (OXTR) have been shown to play an important role in glucose metabolism, and pancreatic islets express this ligand and receptor. In the current study, OXTR expression was identified in α-, β-, and δ-cells of the pancreatic islet by RNA hybridization, and OXT protein expression was observed only in β-cells. In order to examine the contribution of islet OXT/OXTR in glycemic control and islet β-cell heath, we developed a β-cell specific OXTR knock-out (β-KO) mouse.

Estrogen deficiency during menopause plays a major role in post-menopausal osteoporosis by influencing bone, immune, and gut cell activity. In the gut, estrogen loss decreases tight junction proteins that bind epithelial cells of the intestinal barrier together.

Avian coccidiosis is one of the many disorders that seriously harm birds' digestive systems. Nowadays the light is shed on using Phytochemical/herbal medicines as alternative natural anti-coccidial chemical-free standards. Consequently, this study aimed to investigate the impact of lawsonia inermis powder (LIP), and Acacia nilotica aqueous extract (ANAE), on growth performance, serum biochemical, antioxidant status, cytokine biomarkers, total oocyst count and intestinal histopathology of broiler chickens challenged with coccidiosis.
