Loose house systems are being positively promoted in modern swine industry. While gestation crates have gradually been replaced by gestation pens, most farrowing and lactation sows are still restricted in crates. This study aimed to investigate the effects of different pregnancy environments and...

In recent years, duck production has been changed from conventional free range and open water outdoors to confinement in birdhouses. And the concept of animal welfare in high stocking density begins to be accepted in China. The search of the relationship between growth performance and flock...

Environmental conditions strongly affect experimental animals. As a model organism, zebrafish has become important in life science studies. However, the potential effect of living environment on their behavior and physiology is often overlooked. This work aimed to determine whether tank size...

This study investigated the proteomic characteristics of colostrum for sows housed under different conditions. Among 12 gilts, four were housed in a gestation-crate and farrowing-crate combined housing system (CC) as controls, four were housed in a gestation-pen and farrowing-pen combined housing...

The test used the polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis (DGGE) methods to explore the effects of different stocking density on the microbial flora of duodenum for caged Hy-line Gray laying hens. A total of 1 150 eleven-week-old Hy-line Gray laying hens were...

To study the effect of different stocking densities on the growth of largemouth bass (Micropterus salmoides) cultured in containers in a land-based recirculating aquaculture system (C-RAS), 13,500 fish with initial average body mass of 137.3 ± 5.46 g were selected and stocked at 1000 fish/container ...

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...

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...

Environment can affect sows behavioral pattern by creating their physiology and psychology imbalances, and postpartum behavioral pattern of sows is related closely with piglet mortality. However, few studies have focused on effects of pregnancy and lactation environments on Postures of primiparous...

The Integrated Multi-Trophic Aquaculture (IMTA) of sea cucumbers and sea urchins has high commercial values. The consumption of sea urchin feces by sea cucumbers is important but largely unknown. The present study aims to evaluate and subsequently improve the fecal consumption in sea cucumbers. Sea ...
