and in invasive wild boars () and hunting dogs from Brazil.

The wild boar, an impactful invasive species in Brazil, is subject to population control activities, which often include the use of hunting dogs. Hunters commonly consume wild boar meat, which is also used to feed their dogs, posing a risk of infection for humans and both and for dogs. The study aimed to investigate the prevalence of infection in wild boars (n = 127) and hunting dogs (n = 73) from São Paulo, Rio Grande do Sul, and Paraná states.

Impact of combined management strategies of monensin and virginiamycin in high energy diets on ruminal fermentation and nutrients utilization.

Feed additives such as monensin (MON) and virginiamycin (VM) are commonly utilized in feedlot diets to enhance rumen fermentation. Nevertheless, the precise effects of combining MON and VM during specific feedlot periods and the advantages of this combination remain unclear. This study was designed to investigate the effects of withdrawal of MON when associated with VM during the adaptation and finishing periods on ruminal metabolism, feeding behavior, and nutrient digestibility in Nellore cattle.

Assessment of transplacental transmission of Neospora caninum and Toxoplasma gondii in Neotropical deer: An estimative based on serology.

Transplacental transmission of Neospora caninum and Toxoplasma gondii is well known in some domestic species and despite both parasites having been proved to infect deer fetuses during gestation, the congenital transmission rate in South-American deer species is still unknown. This study aimed to estimate the congenital transmission rate of neosporosis and toxoplasmosis in captive deer populations from Brazil, through serological techniques (IFAT and ELISA). Serum samples from 82 deer were tested by both techniques 20.

Evaluation of potential reproductive seasonality in brown brocket deer (Mazama gouazoubira) bucks.

Photoperiod is the main cue that controls seasonal reproduction in deer from temperate regions, like secretion of testosterone by the testis, neck enlargement, and testis development. However, little is known about its effect on the reproduction of tropical deer species. This research aimed to assess the potential seasonality of the brown brocket deer (Mazama gouazoubira) by melatonin treatment.

xCO2 temporal variability above Brazilian agroecosystems: A remote sensing approach.

Agriculture and soil management practices are closely related to CO emissions in crop fields. These practices directly interfere on the carbon dynamics between the land and atmosphere. In this study, we investigated the temporal variability of the column-averaged dry-air mole fraction of atmospheric CO (xCO), solar-induced chlorophyll fluorescence (SIF), and the normalized difference vegetation index (NDVI) in areas with the main agroecosystems in southern-central Brazil as a way to understand if and how crops cycle and agricultural management could be associated with the temporal variability of NDVI, SIF and xCO.

Feeding behavior of growing and finishing pigs fed different dietary threonine levels in a group-phase feeding and individual precision feeding system.

Derivation and Differentiation of Canine Ovarian Mesenchymal Stem Cells.

Interest in mesenchymal stem cells (MSCs) has increased over the past decade due to their ease of isolation, expansion, and culture. Recently, studies have demonstrated the wide differentiation capacity that these cells possess. The ovary represents a promising candidate for cell-based therapies due to the fact that it is rich in MSCs and that it is frequently discarded after ovariectomy surgeries as biological waste.

Comparison of two total cellular fatty acid analysis protocols to differentiate Rhizoctonia oryzae and R. oryzae-sativae.

Two fatty acid analysis protocols (the MIDI and a modified MIDI method) were investigated for their utility to characterize and differentiate Rhizoctonia oryzae and R. oryzae-sativae isolates from four countries. Only the modified MIDI method permitted a clear differentiation between the two species, regardless of the isolates' country of origin.
