Welfare-oriented housing system for laying hens has started to be explored in China in recent years, while it has been developed for 30 years in America and other countries in the world and achieved much research progress. After the European Union (EU) promulgated the ban of conventional cages,...

In the hot summer, the structure of goat house and stocking density are the key factors affecting the goat house micro-climate conditions. In order to correctly evaluate the goat types and reasonable design of stocking density, this study examined the air parameters of three goat houses, which were ...

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...

The aim of this research was conducted to investigate differences of two welfare indicators of laying hens, including the feather damage and leg health, under floor housing with two different stocking densities and conventional cage system. A total of 150 ISA laying hens were randomly allocated...

Purpose: To study the effects of farrowing pen and farrowing crate on behaviors of lactating sows. Method: Min pig and Yorkshire sows with similar parity, pregnancy and body condition were assigned randomly to the farrowing pen and the farrowing crate to compare the posture state, the frequencies...

The experiment was conducted to investigate the effects of dietary protein source and stocking density on growth performance, body composition and serum biochemical parameters of grass carp (Ctenopharyngodon idellus). A two-factor orthogonal experiment (3×5) was used to evaluate the effects of...

This experiment was conducted to study the effects of stocking density on rearing environment and growth performance and serum biochemical, immune, antioxidant and stress indices of growing pigs in winter. A total of 330 healthy 21 days of age weaner Large White × Landrace (LY) growing pigs with...

Objective: On account of history environmental factors such as temperature and humidity in farrowing houses, based on the data of a farrowing house of a modern pig farm in Guangdong Province, the temperature prediction model of pig house was studied based on time series and multivariate models....

This study was to investigate the effect of stocking density on growth performance, footpad dermatitis score, and dressing percentage of meat-type tom turkeys. Eighty B.U.T. 6 male birds were purchased from a commercial hatchery at 10 days of age. They were randomly allotted into 8 pens. After 68...

This experiment was conducted to investigate the effects of dietary supplemented with alpha-lipoic acid (LA) on the serum indexes, behavior and bone development of broilers under high stocking density condition. In the experiment, a total of 1 530 Arbor Acres AA broilers at the age of 21 days with...
