Abstract:

Crossed adoptions based on female potential are recommended in commercial production. This are made in the first 24 hours postpartum because it is at this moment that the imprinting occurs, it is the process by which certain stimuli are associated to produce different behaviors. In order to decrease or eliminate the recognition of the strange piglet, prior to introducing it into the new litter, different strategies are carried out. Early experiences may have long-term effects on future behavior. These experiences are influenced by mother-litter interaction. The aim of this work was to determin

Abstract:

Against the backdrop of precision livestock farming, sow behavior analysis holds significant theoretical and practical value. Traditional production methods face challenges such as low production efficiency, high labor intensity, and increased disease prevention risks. With the rapid advancement of optoelectronic technology and deep learning, more technologies are being integrated into smart agriculture. Intelligent large-scale pig farming has become an effective means to improve sow quality and productivity, with behavior recognition technology playing a crucial role in intelligent pig farmin

Abstract:

Understanding how piglets move around sows during posture changes is crucial for their safety and healthy growth. Automated monitoring can reduce farm labor and help prevent accidents like piglet crushing. Current methods (called Joint Detection-and-Tracking-based, abbreviated as JDT-based) struggle with problems like misidentifying piglets or losing track of them due to crowding, occlusion, and shape changes. To solve this, we developed MSHMTracker, a smarter tracking system that introduces a motion-status hierarchical architecture to significantly improve tracking performance by adapting to

Abstract Sows exhibit changes in behavior as they approach estrus that could aid in identifying the optimum time for insemination. The objective was to monitor changes in posture of sows from weaning to the first day that sows exhibited standing reflex. A cross-sectional survey was carried out using 99 multi-parous sows (in 7 groups) that were monitored over an 11–d period following weaning. At weaning, sows were moved from a farrowing to a breeding facility and were housed in individual stalls. Sows were checked daily for standing reflex from d 4 to 8 post-weaning; 97 sows exhibited standing

Sows’ maternal behavior is important for improving piglet survival and growth; thus, breeding for good mothering sows is necessary for pig production. However, there is little research on the genetic mechanism of maternal behavior. In this study, a comparative analysis of piglets’ growth traits between good and bad maternal behavior groups and a genome-wide association study (GWAS) was performed to elucidate the impact of sows’ maternal behavior on piglet growth and identify candidate genes and markers of sow’s maternal behaviors.

Abstract Domesticated sows are highly motivated to perform nesting behavior prior to farrowing. However, due to the potential for clogging slurry systems, large amounts of nesting material are not practical to use in most production systems. Therefore, the study objective was to assess an alternative nesting material provided prior to farrowing on sow welfare and reproductive outcomes. We hypothesized that the provision of jute nesting material would decrease sow stress and improve reproductive outcomes.

The adoption of temporary sow confinement could improve animal welfare during farrowing for both the sow and the piglets.

Abstract:

The weaning of pigs in most commercial pork production systems is an abrupt event performed at a fairly young age, i.e., mostly between 2.5 and 5 weeks of age. This practice induces a stress response, and its impact on behavior, performance and the gastrointestinal tract has been well described. Historically, there has been a focus on pre- and post-weaning nutritional strategies and post-weaning housing conditions and medication to improve production and reduce mortality after weaning.

Abstract:

Abstract In modern swine production, most of the sows are housed in a cage system in the farrowing unit. Although this system is intended to reduce preweaning mortality, the welfare of the sow might be compromised as it greatly restricts their natural behavior. Free farrowing systems allow sows to move around in the farrowing pen, which might stimulate their nesting behavior, shorten the farrowing duration and improve locomotion score, therefore, optimizing the longevity of the sows. However, the risk of increased preweaning mortality in free farrowing systems is greater compared with cage sys

Abstract:

The present study aimed to investigate the effect of milk liquid and powder supplements on piglets’ performance, drinking behavior, and sow back-fat thickness change during the lactation period. There were 4 experimental groups (n = 24), and in the control group (n = 6), the piglets were suckled from the sow. For the supplemental groups (n = 18), milk powder (MP), milk liquid by feeding trough (MLFT), and milk liquid feeding by the bucket (MLFB). There were significant differences in average daily weight gain between day 14 and weaning age for the MP and MLFT (p < 0.05) but not in MLFB (p &

Abstract:

Abstract Increasing sow mortality continues to challenge pig producers in the U.S. Sow mortality is an animal well-being, economic and sustainability concern. The majority of sow death loss occurs during late gestation and lactation. Unborn piglets are not able to survive when a sow dies in late gestation. During lactation, sow death (depending on stage of lactation) reduces the availability of colostrum, milk and number of functional teats available to a batch of piglets. Hence sow mortality impedes reproductive throughput. The author characterized sow mortality and evaluated nutritional inte

Effects of distillers’ dried grains with solubles on behavior of sows kept in a group-housed system with electronic sow feeders or individual stalls. Can. J. Anim. Sci. 93: 57–66. A study was conducted to investigate the effects of diets that contained distillers’ dried grains with solubles (DDGS) on stereotypic behaviors of gestating sows housed in stalls and aggression in a group-housed system. Sows were fed corn–soybean-based control (CON) or treatment (DDGS) diets starting from thei

Abstract:

Abstract Our objective was to determine the effects of fiber supplementation during gestation on sow and piglet performance. A total of 200 PIC Camborough P1+ sows were used. At breeding, sows were balanced by body weight (BW) within parity and randomly allotted to 1 of 2 dietary treatments, which consisted of 1) Control; corn-soybean meal gestation diet; and 2) Fiber; inclusion of soybean hulls in the formulation at a level to yield a dietary crude-fiber content 6%. Females were housed in individual stalls throughout the entire gestation. At d 90 of gestation, serum glucose, fecal dry matter,
