In recent decades, goose production has become more specialized and widespread, and rearing geese in plastic wire-floor pens is common in China. This type of rearing pattern is more productive than other rearing patterns since it allows for more birds per square meter. However, it brings some...

This study investigated the effects of indoor stocking density on performance, egg quality, and welfare status of a native chicken, Beijing You Chicken (BYC), during 22 to 38 wk. A total of 1,040 19-wk-old BYC pullets were randomly allocated to 4 groups (2 replicates each) and reared in 8...

Leech Poecilobdella manillensis with body weight of over 1.5 g were reared in net cages of each 35.0 cm × 14.5 cm × 11.5 cm with moist soil bottom at a depth of 6.0 cm and effects of stocking density, feed formulation and feeding frequency on survival and growth in the leech were investigated by a...

This experiment was conducted to evaluate the effects of stocking density on the growth performance, feather growth, intestinal development, and serum parameters of geese. In total, 336 healthy, 28-day-old, male Yangzhou goslings were randomly allotted to 30 plastic wire-floor pens according to 5 ...

The growth and survival of pearl oyster postlarvae (Pinctada martensii) were studied under laboratory conditions. A face-centered central composite experimental design was used with 3 factors, temperature (18-34°C), algal ration (5-100 cells μL^-1) and stocking density (0.2-3.0 in.. mL^-1). Pearl...

The study aimed to investigate the effects of lighting pattern and photoperiod on range use, feather cover and gait score of native laying hens. Six hundred and thirty 19-wks-old Beijing You Chicken (BYC) pullets were randomly allocated to 6 groups with 105 birds each, 3 replicates per group,...

Hens are raised apart from roosters in modern poultry production, a substantial change from their natural social structure. We compared productivity, injuries, behavior, physiology, microbiome and transcriptome of hens housed with (R+) or without (R-) roosters to quantify the effects of this change ...

The heat stress response of broilers will adversely affect the large-scale and welfare of the breeding of broilers. In order to detect the heat stress state of broilers in time, make reasonable adjustments, and reduce losses, this paper proposed an improved Cascade R-CNN (Region-based Convolutional ...

RNA/DNA ratio (RDR) has been reported to be a feasible biochemical indicator for measuring the growth of numerous aquatic animal species. Nevertheless, its applicability has not been investigated to date in the pearl oyster Pinctada fucata (Gould, 1850). A laboratory experiment was undertaken to...

Context: Broilers are prone to immunological stress when subjected to unsuitable environmental conditions (such as virus attack, nutrient deficiency and high stocking density), lowering immunity and resulting in inflammatory bowel diseases. The herb-feed additive Artemisia argyi has been applied in ...
