ABSTRACT - An outbreak of Ricinus communis poisoning in goats with neurological and digestive changes was related to the ingestion of different vegetative parts of the plant. Two poisoned animals died within 5 h of the plant intake showing necrotic gastroenteritis and hepatocytes degeneration and necrosis. Toxicological analysis by HPLC-DAD assay demonstrated 21.1?25.1 μg/g of ricinine in samples of ruminal fluids and 10.1?10.9 μg/g in the liver of poisoned goats. © 2022

Abstract: Fasciola hepatica, a worldwide-distributed liver fluke, is one of the causative agents of fasciolosis, a zoonotic disease that affects livestock and humans. In livestock, fasciolosis causes huge economic losses worldwide, reducing animal fertility, milk production, weight gain and condemnation of livers. In spite of the availability of drugs, such as triclabendazole (TCZ), for the treatment of fasciolosis, they do not necessarily prevent liver damage or parasite reinfection and can eventually increase parasite resistance.

Abstract: This study aimed to integrate GWAS and structural variants to propose possible molecular biomarkers related to gastrointestinal nematode resistance traits in Santa Inês sheep. The phenotypic records FAMACHA, haematocrit, white blood cell count, red blood cell count, haemoglobin, platelets and egg counts per gram of faeces were collected from 700 naturally infected animals, belonging to four Brazilian flocks. A total of 576 animals were genotyped using the Ovine SNP12k BeadChip and were imputed using a reference population with Ovine SNP50 BeadChip.

RESUMEN: Los tambos industriales suelen tener conflictos con palomas que consumen el alimento del ganado, alterando la composición de la dieta y contaminando la ración. Durante 2017-2018, en un tambo industrial de Durazno (Uruguay), con una población de 10.000 animales estabulados, se identificaron las especies de aves involucradas y se evaluaron daños. Las pérdidas de alimento se midieron en kilogramos de Ración Totalmente Mezclada (TMR) en tres corrales, y de suplementos y granos para preparar la TMR en celdas de almacenamiento.

Abstract: Fusarium head blight (FHB) and stem rust (SR) threaten the sustainability of wheat production worldwide. Fhb1 and Sr2 confer partial durable resistance to FHB and SR, respectively. Despite resistant alleles of both genes are linked in repulsion, lines with Fhb1-Sr2 in coupling were developed at the University of Minnesota, USA. Marker-assisted backcrossing was used to incorporate the coupled Fhb1-Sr2 into four elite INIA-Uruguay spring wheat varieties lacking both genes and expressing different levels of FHB and SR resistance.

ABSTRACT.- Orange fruit are sensitive to develop chilling injury (CI) during postharvest storage. Symptoms are brown depressed areas in the flavedo that coalesce with time causing severe economic losses. Abscisic acid (ABA) is applied during preharvest in different crops to promote cold tolerance but its effect in citrus fruit remains unknown. The objective of this work was to study the effect of preharvest application of ABA in alleviating CI during cold storage (1.0 ± 0.5°C). ABA at 500 mg.L−1 was applied at three different maturity stages of ?W. Navel?, ?Valencia? and ?Salustiana?

ABSTRACT.- This study compares the technical and financial performance of different beef cattle production systems and assesses the opportunistic commercialization practiced in these systems.

ABSTRACT.- Pascalia glauca is a native weed and one of the most common hepatotoxic plant affecting cattle in Argentina. Although experimental P. glauca poisoning have been reported in sheep, no spontaneous cases have been reported in this species. This work describes an outbreak of intoxication after spontaneous consumption of P. glauca, affecting 20% (6/30) sheep of a commercial flock. Affected sheep were ataxic, depressive, with mucous nasal discharge, cough and abdominal breathing.
