Background And Aim: are Gram-negative, aerotolerant spirochetes that colonize the large intestine of various species of domestic animals and humans. The aim of this study was to determine the presence and distribution of different species of Brachyspira presents in feces from finishing pigs in Argentina.
Materials And Methods: Fecal samples (n=1550) were collected from finishing pigs in 53 farms of the most important swine production areas of Argentina, and species were identified by bacteriological and molecular methods.
Results: The regional prevalence of spp. was at the level of 75.5% (confidence interval 95%, 62.9-87.9), and it was lower among those farms with >1001 sows. One hundred and twenty-eight isolates of were properly identified and the species found were: , , , and . and had low prevalence (1.9% and 7.5%, respectively), was isolated from 34% of the farms and was found in 39.6%.
Conclusion: The present study provides epidemiological data about herd prevalence of the different species in Argentina, showing that the prevalence figure seems to be higher than that reported in other countries.

This study aimed to evaluate the effects of dietary fat source and feeding duration on growth performance, carcass characteristics, and meat quality of finishing pigs. A total of 450 twenty-one-week-old finishing pigs with an average body weight of 113.7 ± 8 kg were housed in 90 pens assigned to one of five dietary treatments in a 2×2 + 1 factorial design.

Respiratory diseases, such as pleurisy and pneumonia, cause significant health and economic losses in pig production. This study evaluated 867 finishing pigs from a farm with a history of respiratory issues, using macroscopic lesion scoring (SPES and CVPC), histopathological analysis, qPCR diagnostics, and economic modeling. Severe pleurisy (scores 3 and 4) was observed in 42.

Choline is vital in a variety of physiological processes that influence brain development, growth, and carcass characteristics in birds and mammals. In this study, we investigated the influence of graded supplemental choline chloride on growth performance, carcass quality, and liver characteristics in grow-finish pigs. Pigs (672 barrows and 588 gilts) were obtained from a commercial nursery facility at 8 weeks of age and assigned to treatment based on body weight and sex, with 21 same-sex pigs comprising a replicate pen.

The effects of incorporating Illipe nut into the diet of pigs, in replacement of yellow maize, on their growth performance and meat quality was investigated in a 60 days feeding trial. Twenty-four male pigs were divided into two treatments and fed diets with 0% (T1) or 15% (T2) Illipe nut inclusion. Feed intake, live weight (LW) and backfat thickness (BFT) were taken and used to calculate average daily feed intake (ADFI), average daily gain (ADG), feed conversion ratio (FCR) and increase in backfat (IBF).
