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 total of 129 herds ( = 12,364 sows) were included in the study.

Surgical treatment of a colon neoplasm of the splenic flexure: a multicentric study of short-term outcomes.

Aim: The optimal surgical treatment of splenic flexure neoplasm is still not well defined. Extended right hemicolectomy (ERH) and left colic resection (LCR) have been proposed but conclusive evidence concerning postoperative morbidity and oncological results is lacking. The aim of this study was to analyse the short-term outcomes after surgery for splenic flexure cancer with regard to surgical procedure and surgeon's specialty.

Toxicity assessment of 2,4-D and MCPA herbicides in primary culture of fish hepatic cells.

In this study, we used primary cultures of fish hepatic cells as a tool for evaluating the effects of environmental contamination. Primary hepatic cell cultures derived from the subtropical fish Metynnis roosevelti were exposed to different concentrations (0.275, 2.

First report of Porcine teschovirus (PTV), Porcine sapelovirus (PSV) and Enterovirus G (EV-G) in pig herds of Brazil.

Porcine teschovirus (PTV), Porcine sapelovirus (PSV) and Enterovirus G (EV-G) have been associated with enteric, respiratory, reproductive and neurological disorders. Although Brazil is the world's fourth largest producer and exporter of pork, no information on the occurrence of PTV, PSV and EV-G infections is available for Brazilian pig herds. This study aimed to investigate the occurrence of Porcine enteric picornavirus infections in pig farms located in three distinct geographical regions of Brazil.

Growth of suckling piglets in litters standardized by weight.

This study examined the relationship between birth weight and growth performance when suckling piglets were reared in litters standardized by birth weight. Forty-four gilts (Landrace × Large White) due to farrow during the same week were selected. Piglets born to those gilts were individually weighed at birth and cross-fostered to obtain litters with 11 piglets and standardized birth weight (CV, lower than 5%).
