Housing systems are among the most important non-genetic factors affecting hen production performance and intestinal microbes. With increased interest in animal welfare, cage-free laying hen housing systems have become common, providing behavioral freedom and health benefits. The present study...

Wild Alpine musk deer (Moschus chrysogaster), which are native to the Qinghai-Tibet Plateau and surrounding areas, have been kept in captivity as an effective way to conserve musk deer ex situ and sustainably utilize musk resources. From 1 November to 31 December of 2019, the behaviors of 40...

This study investigated the characteristics and performance of a positive pressure head-space ventilation with drip cooling system in a pig farrowing facility in southern China. Equations were established that estimate ventilation rates of head-space ventilation system for different air velocity...

1. High stocking densities can lead to animal stress responses and lead to changes in bird behaviour, egg production and the fertility of laying birds. The oviduct plays a crucial role during the process of laying eggs. Therefore, it is essential to know how high stocking density affects oviduct...

The effects of four different-sized cages - huge (HC), large (LC), medium (MC), and small (SC) cages - on the productive performance, serum biochemical indices, and caecal microbiota composition of Roman laying hens were investigated. At 44 weeks of age, a total of 450 hens were selected and...

Animal behavior, including agonistic behavior, is regulated by various neurotransmitters and hormones in the blood. To Identify blood-based biomarkers associated with aggression in weaned pigs after mixing, a total of 500 weaned pigs from 65 litters were selected and mixed into 51 pens with...

To investigate the correlation between lipid deposition variation and stocking density in Amur sturgeon (Acipenser schrenckii) and the possible physiological mechanism, fish were conducted in different stocking densities (LSD 5.5 kg/m³, MSD 8.0 kg/m³, and HSD 11.0 kg/m³) for 70 days and then the...

Re-location and mixing after weaning increase the risk of aggression in weaned pigs. To quantify the effects of tail docking, teeth clipping and toy enrichment on the growth performances, behaviour, lesions, and physiological indicators of weaned pigs after re-location and mixing, a total of 262...

A series of experiments were conducted to evaluate the effects of temperature, salinity, diet, and stocking density on the growth, survival, and metamorphosis of geoduck clam Panopea japonica larvae. The larvae all died at a temperature of 22°C after day 12, suggesting that the larvae of P....

The positive reinforcement training for captive animals is a general trend for zoos at home and abroad. In recent years, zoos around China have also developed trainings in succession, and had some achievements. Nanning Zoo began to carry out positive reinforcement training for a Panthera tigris...
