1. The purpose of this study was to determine the metabolisable energy of high-protein distiller's dried grains with solubles (HP-DDGS) for meat quail (; Experiment I) and evaluate the effects of dietary levels of HP-DDGS on animal performance, carcase characteristics, meat quality, and organ weights (Experiment II).2. In Experiment 1, 96 meat quail were distributed in a completely randomised design with two treatments (reference or test diet) and six replicates of eight birds. The experimental period consisted of 5 d adaptation, followed by 5 d total excreta collection. The experimental diets consisted of a reference (control) and a test diet formulated with 800 g/kg reference diet and 200 g/kg HP-DDGS.3. In Experiment 2, 612 meat quail were distributed in a completely randomised design fed one of six dietary levels of HP-DDGS (0, 85, 170, 255, 340, or 425 g/kg) as a replacement for soybean meal. At 42 d of age, birds were slaughtered and evaluated for carcase yield, organ weights, and meat quality.4. Apparent metabolisable energy values corrected for nitrogen retention of HP-DDGS were 12.5 and 12.3 MJ/kg for males and females, respectively.5. In the starter phase (1-21 d of age), increasing dietary HP-DDGS levels had a quadratic effect on body weight (BW) (P = 0.020) and body weight gain (BWG) (P = 0.019). The maximum BW and BWG values were estimated to be achieved with 296.0 and 296.2 g/kg dietary HP-DDGS, respectively. Overall (1-42 d of age), increasing dietary HP-DDGS levels in replacement of soybean meal did not affect animal performance, carcase yield, meat quality or organ weight in meat quail.6. It was concluded that dietary HP-DDGS can fully replace soybean meal in meat quail diets without affecting growth performance, carcase yield, meat quality or organ weight.

The breeding and exploitation of chickens at the backyard or commercial family level is an activity of great economic relevance for families in Ecuador. In addition to providing protein of high biological value for food security, it revalues local food resources that could provide productive benefits. With this objective, a study has been conducted in order to explore the effect of C.

The utilization of exogenous fiber-degrading enzymes in commercial swine diets is a strategy to increase the nutrient and energy density of poorly digestible ingredients. In a prior set of studies, dietary multienzyme blend (MEblend) supplementation increased the apparent total tract digestibility (ATTD) of nutrients, non-starch polysaccharides, and energy in complete high-fibrous gestation diets by 6% when fed to gestating sows. The current study aimed to determine the effects of MEblend (containing xylanase, β-glucanase, cellulase, amylase, protease, pectinase, and invertase activities) supplementation on ATTD of energy and nutrients of individual feedstuffs commonly used in gestating sow diets across major pork-producing regions worldwide, which differ in their fibrous components.

Objective: To investigate the effects of light fasting diet therapy, including flaxseed powder supplementation, on lipid metabolism and sex hormone levels in patients with polycystic ovary syndrome (PCOS) combined with infertility.
Methods: A total of 104 PCOS patients with combined infertility were divided into the control group ( = 52) and intervention group ( = 52) using a random number table method. Over a two-month study period, the control group received light fasting diet therapy with rice flour as a placebo, while the intervention group received light fasting diet therapy supplemented with flaxseed powder.
Globally, many species are threatened by population decline because of anthropogenic changes leading to population fragmentation, genetic isolation and inbreeding depression. Genetic rescue, the controlled introduction of genetic variation, is a method used to relieve such effects in small populations. However, without understanding how the characteristics of rescuers impact rescue attempts interventions run the risk of being sub-optimal, or even counterproductive.

Background: Attention-Deficit Hyperactivity Disorder (ADHD) is a complex disease that negatively impacts the social and academic/occupational activities of children and is more common in boys than in girls.
Methods: This case-control study aimed to assess the association between some environmental risk factors and ADHD among children in Alexandria, Egypt. It was carried out at the outpatient clinics of El Shatby Pediatric University Hospital in Alexandria, Egypt, with 252 children (126 cases and 126 controls).
