This experiment was conducted to investigate the effects of stocking density on laying performance, egg quality, intestinal morphology, and serum biochemical, antioxidant and immune indices of laying hens. A total of 432 healthy 30-week-old Hy-Line brown laying hens were randomly divided into three ...

Stocking density is a biotic factor affecting the production of cultivated animals in aquaculture. Herein, a rearing trial was conducted to investigate the impact of stocking density on the survival, growth performance and physical injury of Marsupenaeus japonicus juveniles in a flowing water...

Background: High stocking density (HSD) stress has detrimental effects on growth performance, intestinal barrier function, and intestinal microbiota in intensive animal production. Organic acids (OA) are widely used as feed additives for their ability to improve growth performance and intestinal...

Objective: In this study, sensory evaluation, electronic nose detection, electronic tongue detection and texture analyzer detection were used to determine the differences in egg yolk flavor between traditional caging regime and furnished caging regime, to provide basic data on the egg yolk flavor....

Penconazole (PEN) is a typical systemic triazole fungicide with cardiac toxic effects. Resveratrol (RES) is a natural polyphenolic phytochemical with antioxidation properties. This study aimed to investigate if RES could protect against PEN-induced cardiotoxicity and to determine the underlying...

In fish, aggression has significant individual differences, and different personalities exhibit distinct behavioral performances and physiological stress responses. Under intensive culture conditions, Sebastes schlegelii juveniles display severe aggression and cannibalism, causing damage to fish ...

Public concerns regarding animal welfare are changing the selection of rearing systems in laying hens. This study investigated the effects of rearing systems on eggshell quality, bone parameters and relative expression levels of genes related to bone remodeling in aged laying hens. A total of 2,952 ...

Domestication has altered a variety of traits within the Eurasian perch (Perca fluviatilis), including phenotypic, physiological and behavioral traits of Eurasian perch (Perca fluviatilis). Little is known, however, about the genetic changes between domesticated and wild Eurasian perch. In this...

The Black Muntjac (Muntiacus crinifrons) is a rare and endangered protected animal endemic to China, but studies on the behavior and enclosure selection of captive Black Muntjacs are very limited. In this study, we used transient scanning method to observe and analyze the behavior of 18 captive...

The microecological preparation is a new type of green feed additive made according to the principle of microecology. Its mechanism of action is to maintain the balance of intestinal flora, improve the intestinal barrier function, and enhance the immunity. As a substitute for feed antibiotics,...
