RESUMEN.- El objetivo de este estudio fue estimar parámetros genéticos aditivos de la condición corporal al primer (BCS1) y segundo parto (BCS2), días al primer (DC1) y segundo parto (DC2), peso de la vaca al primer parto (WFC), primer intervalo interparto (CI1), y días de vida productiva (LPL). Las correlaciones genéticas favorables

ABSTRACT.- The black-tufted marmoset (Callithrix penicillata), commonly found in urban areas of Central Brazil, is vulnerable to pathogen spillover from domestic animals and humans. Here, we report an outbreak of natural canine distemper virus (CDV) infection among urbanized free-ranging black-tufted marmosets. Five fatalities occurred in marmosets living in a neighborhood with unvaccinated dogs. Clinically, affected marmosets had lethargy, ataxia, mucocutaneous ulcerations, and crusting lesions.

"Las autoridades de INIA, con el compromiso de todo el personal, venimos impulsando desde marzo una serie de acciones que buscan situar a INIA en la agenda

ABSTRACT.- Rotational crossbreeding is a simple and scalable alternative that combines the advantages of two breeds and captures up to two-thirds of the potential heterosis. With the aim of promoting the complementary use of Corriedale (C) and Dohne Merino (DM) sheep breeds in Uruguay, we have conducted a rotational crossbreeding experiment since 2015 at Estación Experimental Bernardo Rosengurtt (Cerro Largo) of Facultad de Agronomía. This study provides quantitative

ABSTRACT.- Grasslands are among the most human-modified biomes worldwide due to the expansion of croplands and afforestation. In the scenario of productive intensification, it is necessary to generate alternatives to model land-cover changes and their environmental consequences. This study aimed to generate land-cover projections and quantify the impact of these changes on ecosystem service supply in Uruguay. To achieve this, we used land-cover maps, Markovchain models and an ecosystem services supply index (ESSI).

ABSTRACT.- In a collaborative effort with private agents of the oilseed industry, INIA conducted a research study to determine the feasibility of framing soybean production in Uruguay into a sustainable development pathway. A spatial model based on land suitability analysis and the imposition of other soil restrictions (risk erosion, current regulations, and permanent soil uses) was adopted to estimate potential soybean yields and the most suitable cropping areas in the country.

ABSTRACT.- The CRILU program promotes the production of high-quality Merino wools, including fine, superfine, and ultrafine categories. This study aimed to evaluate the effect of wool type (medium, fine, superfine, and ultrafine) on eleven key quality characteristics using non-parametric statistical methods. -------------- RESUMEN.- El programa CRILU promueve la producción de lanas merino de alta calidad, incluyendo las categorías fina, superfina y ultrafina.

ABSTRACT.- The objective of this systematic review and meta-analysis was to evaluate the effect of probiotic supplementation on ADG, feed intake, and feed efficiency (FE) of dairy calves. A secondary objective was to assess outcomes stratified by probiotic type. Our study included quasirandomized and randomized controlled trials written in English, Spanish, or Portuguese that assessed the effects of probiotic supplementation on the growth of dairy calves. No restrictions were placed on the publication year.

In this text we offer a vision to enhance the scaling of the existing niche and contribute to the ST of livestock family farming through an extension policy and discuss the challenges that this implies for rural extension in Uruguay.

Uruguay is historically related to livestock production and Campos ecosystems is a crucial for providing feeding to extensive livestock systems. These rangelands feature a diverse multispecies canopy, essential for biodiversity maintenance, soil erosion control, biogeochemical cycles regulation, scenic beauty, and culture.
