Sows experiencing more severe white line lesions and heel overgrowth and erosion had poorer farrowing performance, regardless of parity order, in Brazilian commercial herds Open
Background Claw lesions are a major contributor to lameness, significantly affecting sow welfare, yet the relationship between farrowing performance and lesion severity is underexplored. This study used a multivariate approach to examine t…
Claw lesion status in Brazilian commercial sow herds from 2013 to 2023 Open
Introduction Claw lesions significantly contribute to lameness, greatly affecting sow welfare. This study investigated different factors that would impact the severity of claw lesions in the sows of Brazilian commercial herds. Methods A to…
Deep learning pose detection model for sow locomotion Open
Lameness affects animal mobility, causing pain and discomfort. Lameness in early stages often goes undetected due to a lack of observation, precision, and reliability. Automated and non-invasive systems offer precision and detection ease a…

202 Source matters: long-term effects of nursery sanitary condition and dietary Zinc source and level on growth performance, diarrhea incidence, and carcass metrics of pigs Open
There is growing evidence that requirements for particular nutrients increase when pigs are kept under low sanitary conditions (LSC). It may be hypothesized that dietary zinc (Zn) source can exert influence on immune status, which may infl…

PSI-16 Too Late to Catch up? Parity Order and Baseline Overall Claw Quality Impact on the Responsiveness of Sows to Mineral-Amino Acid-Complex Supplementation: A Case Study Open
Poor claw quality can predispose sows to lameness, which may be counteracted by mineral-amino acid-complex (ZPM) supplementation. The objective was to investigate the effects of parity order (PO) and baseline overall claw quality (BCW) on …

Prevalence and severity of claw lesions in sows in intensive systems in Brazil Open
Swines raised in intensive systems are highly susceptible to claw lesions. Moderate to severe lesions trigger an inflammatory response, causing pain and impairing reproductive and economic performance. Foot lesions in sows can cause consid…

Supplementation of two sources of selenium at different levels in diet of boars and this effect on the seminal quality Open
The spermatic membrane is rich in polyunsaturated fatty acids, which makes it sensitive to the action of reative species of oxygen, which can damage the seminal quality of the scraps. The purpose of this study was to evaluate the effect of…

Effect of the organic minerals zinc, manganese, and copper on growth performance and the locomotor system of finishing pigs Open
Supplementation with complexed minerals influences the growth performance and the integrity of the locomotor system of animals. The aim of this study was to determine the effect of a complex supplementation of organic minerals (metal-amino…
