Psychrotrophic yeasts were isolated from Antarctic soils, selected based on their ability to grow in apple juice at low temperatures, and evaluated as potential biocontrol agents for the management of postharvest diseases during cold storage. Among species recovered, an isolate Leucosporidium scottii, designated At17, was identified a good agent blue gray mold two cultivars. The produced soluble volatile antifungal substances that inhibitory pathogens. Siderophore production also...
The objective of this study was to investigate the effect different body condition score (BCS) at 30 days before calving (−30 days) induced by a differential nutritional management from −100 until −30 on productive parameters, interval first ovulation and blood parameters in primiparous multiparous Holstein cows under grazing conditions 60 post partum. experimental arrangement randomized complete block design, where were blocked according BW expected date then randomly assigned treatments...
Abstract This study evaluated the effect of winter backgrounding feeding system (grazing vs. feedlot) and amount feed offered in feedlot (FO) on average daily gain (ADG) feed-to-gain ratio (FG) during overall winter-spring period (182 days). Forty Hereford female calves (159 ± 25 kg body weight (BW)) were randomly assigned to one five treatments (98 days): grazing grass pasture at a forage allowance 5 dry matter (DM) per 100 BW, or receiving total mixed ration (70% concentrate/ 30% roughage)...
Abstract Lot-feeding growing cattle during winter has multiple benefits at grazing systems such as increasing stocking rate, spring forage utilization and animal performance a season when pasture growth is low. Possible residual effect of feedlot on subsequent needs to be studied. This work aimed understand the winter-feeding system (grazing, GFS vs. feedlot, FFS) feed offered level average daily gain (ADG) dry matter intake (DMI) transition phase.Forty Hereford female calves (159±25 kg)...
Abstract The sensitivity of Venturia inaequalis to trifloxystrobin and difenoconazole was studied in Uruguay. Populations V. were collected from apple orchards with different histories use. Sensitivity populations analysed using a method for testing spore germination published by FRAC , discriminatory concentration 2.0 mg a.i./l. Resistance widespread the region commercial production resistance detected all examined, incidences ranging 3% 95%. highest frequencies found most intensive use...
ABSTRACT Land-use changes from native pastures to forest plantations in humid temperate areas have raised concerns about their potential impact on the environment. This study aimed assess effects of such soil water properties, focusing species planted and relationship with C content. Specifically, we identify development surficial hydrophobicity holding capacity. A long-term experiment variable planting densities (816, 1111, 2066 trees ha -1 ) Eucalyptus grandis Hill ex Maiden Pinus taeda L....
The use of vegetation in cities is one the most promising strategies for urban climate change adaptation and mitigation. Tree shade influences heat storage from surfaces reducing long wave radiation emission which directly affects people. People 's perception depends more on insolation temperature surrounding objects than air itself. There a need analyzes that include combined effects physical human variables thermal comfort, as well location-based studies to address its climatic social...
The use of mixtures pesticides and consecutive pesticide applications challenge current regulations aimed at protecting ecosystem health due to unpredictable effects complex dynamic mixtures. In this study, we tested the ecotoxicological herbicides, applied following a real application scheme soybean production on soil in mesocosm experiment. experiment included two sequential applications; first, glyphosate + dicamba clethodim, 30 days later, flumioxazin metolachlor. Commercial products...

Contents This study aimed at comparing in vitro , ultra‐heat‐treated (UHT) skim milk and INRA‐96 ® ‐based extenders supplemented or not with 5% egg yolk and/or 2% glycerol on sperm quality parameters along 72 h of preservation 5°C, using a factorial design. Semen from six healthy mature Merino rams was pooled extended each medium split sample procedure (six replicates) chilled. Subjective motility (SM) (%), membrane integrity (MI) (%) uncapacitated spermatozoa (US) (×10 6 spermatozoa/AI...
El objetivo de este trabajo fue caracterizar la ocurrencia condicionantes meteorológicas (CM) estivales diferente severidad en Salto (Uruguay) y su impacto sobre las respuestas fisiológicas productivas vacas lecheras. Se caracterizaron CM según el índice temperatura humedad (ITH) promedio, horas al día con ITH ≥72 temperaturas mínima máxima diaria. En los animales, se registró rectal (TR) frecuencia respiratoria (FR) a 6:00 15:00 horas, también tiempo dedicado pastoreo (TP) durante día....
The negative effect of heat stress on dairy cows, with a temperature humidity index (THI) over 72, has been extensively studied. However, there are few studies THI values under 72 that compare the in different lactation stages. objective this study was to determine two stages below threshold 72. Thirty-nine multiparous, non-pregnant Holstein cows more than 30 kg/cow.day solid-corrected milk were used randomised complete block design evaluate six treatments. experimental had 3 by 2 factorial...
El rendimiento promedio de los cultivos comerciales frutilla en el sur del Uruguay es inferior al alcanzable para las condiciones producción, acuerdo a rendimientos experimentales y mejores resultados comerciales, lo cual determina la existencia una brecha (BR). Por otro lado, existe gran variabilidad entre productores. objetivo trabajo fue identificar, jerarquizar analizar factores ambientales manejo que explican brechas cultivo Uruguay. Se evaluaron 76 dos zafras producción muestra 13...
