Objective: Cage rearing has critical implications for the laying duck industry because it is convenient for feeding and management. However, caging stress is a type of chronic stress that induces maladaptation. Environmental stress responses have been extensively studied, but no detailed...

The effects of rearing system and stocking density on growth performance and carcass composition of broilers were investigated in this experiment. Using a 3×2 factors completely randomized design, a total of 504 seven-day-old male broilers (Ross 308) were divided into 6 groups with 6 replicates per ...

The detection of pig growth and monitoring of abnormal behaviors are key steps in pig breeding management. Using conventional methods to obtain information on growth and abnormal behavior causes stress to pigs, directly affects the number of live pigs for market, and decreases the quality of the...

Hens are raised apart from roosters in modern poultry production, a substantial change from their natural social structure. We compared productivity, injuries, behavior, physiology, microbiome and transcriptome of hens housed with (R+) or without (R-) roosters to quantify the effects of this change ...

In order to solve the problem that the complex pig house environment leads to the difficulty and low accuracy of abnormal detection of group pigs, the video of 9 adult fattening pigs were collected, and the video key frames were obtained by the frame differential method as the training set, and the ...

The yellowtail clownfish (Amphiprion clarkii) is a hermaphrodite fish, whose sex differentiation and gonad development are closely related to its social status. The kisspeptin/KissR system is regarded as a key factor mediating social stress on reproductive regulation. In order to understand the...

Heat stress of dairy cows is a non-specific physiological reaction caused by high tempera-ture environment, which can seriously affect the physiological state and embryonic development of dairy cows, and then cause huge economic losses. Therefore, how to improve the development ability of dairy cow ...

Poultry welfare has been extensively studied; however, there is a lack of rigorous scientific knowledge relating to the different aspects of welfare factors and how this may contribute to the production quantity and product quality as well as the welfare of chickens. Therefore, we conducted an...

This study was conducted to investigate the protective effects of dexmedetomidine (DEX) on renal injury caused by acute stress in rats and to explore the protective pathways of DEX on rat kidney from the perspective of oxidative stress. In this study, an acute restraint stress model was used, in...

Post-release dispersal of reintroduced animals refers to the process of successful colonization and failed settlement. To ensure the establishment and persistence of a reintroduced population, the impacts of different factors on the post-release dispersal of captive-bred animals must be assessed....
