Abstract:The aim of this work was to identify causes of abortion through laboratory investigations in sheep flocks in Uruguay. One hundred cases of abortion, comprising 58 fetuses, 36 fetuses with their placentas, and 6 placentas were investigated in 2015?2021. Cases were subjected to gross and microscopic pathologic examinations, and microbiological and serological testing for the identification of causes of abortion, including protozoal, bacterial, and viral pathogens.

Abstract:Neospora caninum is a leading cause of bovine abortion worldwide. Although the genetic diversity of this apicomplexan parasite has long been recognized, there is little information on whether infection with different genotypes results in different clinical outcomes or whether infection by a given genotype impairs protective immunity against abortion induced by different genotypes. Here, we provide evidence supporting that natural subclinical infection with isolate NcUru3 of N. caninum in a pregnant heifer did not provide protection against abortion caused by a different N.

Abstract: Context:Environmental conditions during hot weather decrease feed intake and cattle growth. Aims:This study conducted over three consecutive years, during the summer, evaluated access to shade as a strategy to mitigate heat stress of finishing cattle in Uruguay. Methods:Each year, 32 Bos taurus and/or Bos taurus crossbred steers (initially weighing 461 ± 28 kg) were blocked by initial liveweight and assigned to one of eight pens, where one of two treatments were applied, namely, no shade access or shade access (mean shaded area 4.5 m2/animal).

ABSTRACT.- Animal performance, carcass and meat quality characteristics of beef cull cows under different feeding strategies were compared. Cows were assigned to one of four grazing treatments combining different levels of forage allowance (FA) and supplementation rate (%of body weight, BW) using rice bran (RB):T1= FA2 % + RB0,T2 = FA4 % + RB0, T3= FA2 %+ RB 0.8 % and T4 = FA2 % + RB 1.6 %. Cows from T1 presented lower (P 0.05). Nonetheless, differences between treatments were found in n­6 and n­3 fatty acid contents (P 0.05).

RESUMEN:La fiebre Q es una zoonosis distribuida mundialmente, causada por Coxiella burnetii. Los bovinos, ovinos y caprinos son la fuente más frecuente de infección en humanos, en los que la enfermedad es de notificación obligatoria ante el Ministerio de Salud Pública. Revisamos las publicaciones que describen casos de fiebre Q en humanos en Uruguay, con foco en sus características epidemiológicas, y discutimos las pruebas diagnósticas disponibles localmente. Se incluyeron nueve trabajos publicados e información del registro de enfermedades profesionales.

ABSTRACT.- The fungus Monilinia fructicola, which causes brown rot in fruits, is one of the main peach pathogens. The emergence of fungicide-resistant fungus isolates, as well as the attempt to reduce sprays, favors adoption of other control strategies. Among them, one of the most important is genetic resistance. This study was carried out aiming to evaluate the susceptibility of 16 peach and 4 nectarine genotypes to brown rot, as well as to evaluate how well the sporulation area and diameter correlate with number of spores in the lesions.

The Rio de la Plata region (Argentina, Uruguay, and southern Brazil) is currently characterized by a mosaic of intensively managed croplands and remaining areas of livestock production on native grasslands. The production of crops and animals in this scenario is usually spatially segregated as a result of mindset and structural constraints developed over decades of agricultural specialization. However, several studies have suggested that crop-livestock integration across various spatio-temporal scales can improve land-use efficiency and ecosystem services provisioning.

Human impacts on the Earth's biosphere are driving the global biodiversity crisis. Governments are preparing to agree on a set of actions intended to halt the loss of biodiversity and put it on a path to recovery by 2050. We provide evidence that the proposed actions can bend the curve for biodiversity, but only if these actions are implemented urgently and in an integrated manner
