We propose an optimal system for determining the shipping schedule for pigs using a predictive model using machine learning based on big data. This system receives photographic and weight measurement information for each pig from a camera and a weighing machine installed in a pig pen for raising ...

The purpose of this experiment was to preliminarily compare the digestibility of fiber feed ingredients between Chuanzang black pigs and Duroc×Landrace×Yorkshire (DLY) pigs. Thirty-two Chuanzang black pigs with the body weight of (80.34±3.68) kg and 32 DLY pigs with the body weight of (80.48±2.75)...

Studying gene flow between different livestock breeds will benefit the discovery of genes related to production traits and provide insight into human historical breeding. Chinese pigs have played an indispensable role in the breeding of Western commercial pigs. However, the differences in the...

The purpose of the experiment was to explore the fiber types and energy metabolism characteristics of the longissimus dorsi muscle of Jinfen White pigs. In this study, the longissimus dorsi muscle of 6 month old Jinfen White pigs and Large White pigs was collected, and the diameter and density of...

The protein contents in diets for grower-finisher pigs reflect directly on the pig industry, also allowing to verify the responses of modern genotypes according to the protein feeding regimen. Therefore, this study was conducted to assess low- and high-protein diets and 2 genetic lines on growth...

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...

The cyclical fluctuation in the price of live pigs has caused the phenomenon of "low pig prices affect the interests of enterprises, and high pig prices affect the interests of people", which has had a series of impacts on the development of the live pig industry chain. Based on the data of live ...

The common method of stunning pigs using high concentration carbon dioxide prior to slaughter poses an animal welfare issue, as the gas is aversive. Proof of concept for using nitrogen gas encapsulated in high-expansion foam as an alternative non-aversive method for stunning pigs has recently been...

To investigate the distribution, sequence structure, genetic variation and expression characteristics of porcine endogenous retrovirus (PERV) in different pig breeds, this study selected three common pig breeds, namely the large white, Rongchang and Wuzhishan miniature pigs, as the study materials, ...

Cryptosporidium spp. are significant opportunistic pathogens causing diarrhoea in humans and animals. Pigs are one of the most important potential hosts for Cryptosporidium. We evaluated the prevalence of Cryptosporidium in pigs globally using published information and a random-effects model. In...
