This study was conducted to evaluate the effects of stocking density on productive performance, egg quality, and antioxidant capacity in laying ducks. A total of 720 20-week-old Jinding laying ducks were randomly assigned to 5 stocking densities (4, 5, 6, 7, and 8 birds/m²) with 8 replicate pens...

The effects of rearing system and stocking density on growth performance and carcass composition of broilers were investigated in this experiment. Using a 3×2 factors completely randomized design, a total of 504 seven-day-old male broilers (Ross 308) were divided into 6 groups with 6 replicates per ...

A 3×2 factorial experiment was conducted to determine the effects of rearing system and stocking density on the growth performance, intestinal morphology and fermentation status of broilers. Broilers were kept on three rearing systems: floor litter rearing (FRS), plastic net rearing (NRS) and...

The research was performed to investigate the compensatory growth in gibel carp (Carassius auratus gibelio) after the stress of stocking density; the 8-week growth trial was performed in a proper system of 12 fibreglass tanks. Four different density groups were marked as C (control group), D_1/2, D...

Leash pulling is a concern for dog owners and can be detrimental to the health and welfare of dogs. Neck-collars and back-connection harnesses are popular restraint types. Harnesses have been proposed as a better and more considerate option for canine health and welfare. Anecdotally, dogs pull more ...

The importance of lighting regimen is increasing with the industrialization of poultry production, as lighting has been intimately associated with not only the establishment of rhythm and synchronous physiology of broiler chickens, but also the secretion of hormones associated with broiler...

Taking 31 keepers in Ya'an Bifengxia Base of China Giant Panda Conservation and Research Center as samples, the current welfare status of giant pandas (Ailuropoda melanoleuca) in the base was investigated from five aspects including physiological welfare, environmental welfare, health welfare,...

As aquaculture continues to grow and intensify, there is an increasing public concern over the welfare of farmed fish. Stress and production-related pathologies and repressed growth are examples of the challenges facing aquaculture, and their impacts could be minimised by effective identification...

Suckling behavior is essential for the growth, health, and welfare of the lamb. The factors that influence the suckling-related behavior varied across breeds, and they remain unclear in Small-tailed Han lamb. This study aims to investigate the effects of ewe parity, lamb sex, and birth order on the ...

Sexual dimorphism exists widely in animals, manifesting in different forms, such as body size, color, shape, unique characteristics, behavior, and sound. Of these, body mass dimorphism is the most obvious. Studies of evolutionary and ontogenetic development and adaptation mechanisms of animals'...
