The physiological consequences of overstocking require more investigation, and no research has explored whether dietary supplements could mitigate the anticipated negative physiological effects. OmniGen AF (OG, Phibro Animal Health Corporation, Teaneck, NJ, USA) is a nutritional supplement that has ...

Introduction: To prepare laying hens for life in cage-free aviaries, they must be reared in aviaries that accustom them to the challenges of navigating a complex three-dimensional structure. Rearing aviaries vary in design and contain a brooding compartment in which chicks are confined during the...

Concern about the welfare of broilers kept under intensive management systems is raised mainly in industrialized countries. Most welfare problems are related to early growth. Fast growing broilers were susceptible to sudden death syndrome (SDS), Ascites and leg problems. Using slow growing breeds...

Improving the housing of pregnant sows by giving them more space and access to deep straw had positive effects on their welfare, influenced their maternal behavior and improved the survival of their offspring. The present study aimed at determining whether these effects were actually due to...

The present study was to explore the influence of stocking density on the growth, blood biochemistry, and antioxidant capacity indicators of Chinese perch (Siniperca chuatsi) cultured in the bank (60 cm× 60 cm×40 cm) based recirculating systems for 40d. Fish (average weight 175.76±15.85 g) were...

Scientific research into fish wellness is critical, and the concerns about crowding-related stress due to increased stocking density are inevitable. Taking this into consideration, the study defines the physiological signature of Ompok bimaculatus (Butter catfish) in a biofloc system when subjected ...

Golden pompano (Trachinotus ovatus) is one of the most important cultured marine fish in Southeast Asia. Stocking density affects the growth performance and welfare of fish in aquaculture. A 70-day rearing experiment was performed to evaluate the effect of different stocking densities on the growth ...

With the keeping of lactating sows in loose housing systems, ensuring work safety for stockpersons is gaining importance. Aim of the present study was to develop tests characterising the behaviour of lactating sows in farrowing environments with more freedom to move. The behaviour towards humans in ...

Osteoporosis and bone fractures are a severe problem for the welfare of laying hens, with genetics and environment, such as housing system, each making substantial contributions to bone strength. In this work, we performed genetic analyses of bone strength, bone mineral density, and bone...

This study was conducted to compare the production performance and stress response of chickens kept in the conventional cages and floor pens. 491 female White Leghorns were used in this study, and their production characteristics and stress response indicators were analyzed from 34 to 43 weeks of...
