El módulo de producción intensiva de carne ovina (MPICO) fue un trabajo interinstitucional en la que participaron el Instituto Nacional de Carnes (INAC), el Secretariado Uruguayo de la Lana (SUL), y el Instituto Nacional de Investigación Agropecuaria (INIA), a través de la ejecución de un proyecto Fondo de Promoción de Tecnología Agropecuaria (FPTA) denominado FPTA 354 MPICO. Se generó a nivel demostrativo un módulo de producción ovina en el campo experimental del SUL, ubicado en el Centro de Investigación y Experimentación Dr. Alejandro Gallinal (CIEDAG), Florida.

In Uruguay, anthelmintic resistance in sheep is widely distributed, which has made research into alternative control measures necessary. The objective of this work was to evaluate the effect of a condensed tannins (CT) extract from Schinopsis balansae (Quebracho) (SB) or the effect of a yeast strain of Saccharomyces cerevisiae (LEVUCELL®SC) (SC) against sheep gastrointestinal nematodes (NGI).

In Uruguay, the lack of efficacy of the majority of the anthelmintic drugs available in the market is jeopardicing sheep production systems.

In Uruguay, anthelmintic resistance (AR) is a wide spread phenomenon amongst sheep farms and the main resistant and abundan speciesis Haemonchus contortus (H.contortus). This study aimed to implement the adoption of a targeted selective treatment program using the Famacha© system, to reduce the selection pressure of resistant H.contortus among sheep, under extensive farming.

Desde el año 2002 y aproximadamente cada 5 años, INIA e INAC llevan a cabo un trabajo de investigación denominado "Auditoría de Calidad de Carne", con el objetivo general de caracterizar y determinar la calidad del ganado, de las canales y de la carne en el Uruguay. Este proyecto se enmarca en una línea de investigación de cooperación de INIA con la Universidad de Colorado (EEUU), quien aportó la metodología de trabajo.

ABSTRACT.- The aim of this study was to evaluate the effect of different factors on maternal protective behavior (MPB) of Nellore cows. A total of 3629 cows were evaluated around 24 h after calving, while their newborns were handled for navel care, ear tattoo and weighing. MPB was assessed by observing each cow reactions when its calf was caught in a corral pen. MPB score consisted of 5 levels, going from 1 (the cow paid no attention to the calf and remained indifferent to the procedure) to 5 (the cow showed aggressive behaviors toward the handler, trying to attack).

ABSTRACT.- A Mimosa pudica var. unijuga-associated toxicity affecting horses occurred in Araguari, Triângulo Mineiro, Southeast Brazil. Affected horses had gradual hair loss of the mane and tail and endocrine dermatosis after grazing for three months during the dry season on a paddock invaded by the plant. The main histological lesions include compact ortho-keratotic hyperkeratosis and numerous flame follicles. Toxicological analysis by HPLC-UV demonstrated 0.8 mg/g of mimosine in the leaves. © 2024 Published by Elsevier Ltd.
