ABSTRACT.- Gastrointestinal parasites (GIP) are one of the main causes of economic losses for sheep farmers worldwide. The need for alternative control measures comes from increasingly critical anthelmintic resistance. One alternative is to include genetic resistance to GIP in breeding programmes, by selecting for worm faecal egg count (FEC). Using this selection criterion since 1994, Uruguay has included genetic resistance to GIP in the genetic evaluation of Australian Merino and Corriedale breeds.

ABSTRACT.- Genome enabled prediction of complex traits aims to predict a measurable characteristic of an organism using their genetic information. In the present work we address diverse traits and organisms including Yeast growth, Wheat yield, Jersey bull fertility and various Holstein cattle milk-related traits. We benchmark several popular Machine Learning models: Bayesian and penalized linear regressions, kernel methods, and Decision Tree ensembles. Through exhaustive hyperparameter tuning we outperform state-of-the-art results in most datasets.

El ovino criollo del Uruguay es un recurso zoogenético localmente adaptado, registrado en el Sistema de Información sobre la Diversidad de los Animales Domésticos donde actualmente está catalogado en situación de riesgo (www.fao.org/dad-is). La raza, se originó en el siglo XVIII a partir de la llegada de ovinos procedentes de Buenos Aires, que descendían de los ovinos españoles introducidos durante la colonización.

Desde el año 2019, el Instituto Nacional de Investigación Agropecuaria (INIA) localizado en Las Brujas, departamento de Canelones, cuenta con una población de ovinos criollos compuesta por 101 animales.

ABSTRACT.- Feathering in apple nursery trees is a critical operation used to increase the quality of planting material. Plant growth regulators (PGR) could be used to form feathers in apple nursery trees. The main goal was to study the impact of different PGR and concentrations on feathering promotion in different nursery apple trees.
