In recent years, animal cleanliness during production has gradually attracted increasing attention. Although pigs by nature tend to excrete in dark and humid corners, in the prevalent highly intensive pig production, excessive stocking density often restricts the ability of pigs to excrete at...

Excretion and lying are key behavioral factors that cause pen fouling, thereby affecting pig welfare, pathogen fecal-oral transmission, and air quality in pig housing. This study investigated the effect of space allowance and toy provision on the spatiotemporal distribution of pigs' excreting and...

Increasing space allowance and enhancing environmental enrichment are two approved solutions to improve pig welfare in modern housing systems, while limited research regarding their interactions could be found. To determine the proper stocking density for growing pigs under China's production...

Slatted flooring is an important part of the structure of pig houses and can aid in the removal of pig manure to underground ditches via gravity and locomotion. In this study, four different cast-iron slatted floor configurations with different gap widths (10, 15, and 20 mm) and slat widths (10 and ...

In large-scale sow production, real-time detection and recognition of sows is a key step towards the application of precision livestock farming techniques. In the pig house, the overlap of railings, floors, and sows usually challenge the accuracy of sow target detection. In this paper, a...

The pig industry is one of the mainstay industries of China's agriculture and rural economy. As the core component of pig farms, production performance of sows are the key factors for determining the economic benefits of pig farms. China is the largest pig breeding country in the world, and the...

Background: On October 30, 2020, piglets and sows in the farrowing house of a pig farm in Jiangxi showed clinical symptoms such as anorexia, watery diarrhea, and vomiting. Epidemiological test, clinical necropsy, and RT-PCR test were carried out on the pig farm for diagnosis. After comprehensive...

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...

There is growing public concern about the welfare of farm animals, and farm animal welfare can be considered an ethical attribute of product quality. This paper elicits consumers' willingness to pay (WTP) for animal welfare attributes in pork products using a choice experiment (CE) in China....

The aim of this study was to compare egg quality, carcass, meat characteristics, and bone properties of Taihang chickens in 2 different housing systems at various ages. A total of 168 birds were selected and randomly allocated to 2 groups at 23 wks and raised in conventional cage (CC) or flattening ...
