ABSTRACT: Objective: Our objective was to evaluate the effects of providing shade and shade combined with evaporative cooling on production, cow activity, metabolism, and hepatic gene expression of late-lactation Holstein dairy cows under moderate heat-stress conditions. Materials and Methods: Forty-eight multiparous Holstein cows were used in a completely randomized blockdesign trial and randomly assigned to 1 of 3 treatments: control (CTL), without access to shade; access to artificial shade (SH); and shade combined with evaporative cooling (SHplus). Results were analyzed using a mixed procedure
with repeated measures. Results and Discussion: No differences were observed in DMI. Milk yield was not different among treatments, but lactose concentration was greater in SHplus. Treatments CTL and SH had greater BW losses than SHplus. Control cows spent less time grazing. The CTL and SH had higher p.m. rectal temperatures than SHplus, whereas CTL had the highest p.m. respiration rate. Control cows had greater serum insulin levels. Control and SH had
greater BHB and urea concentrations and lower glucose concentration compared with SHplus. The hepatic expression of PCK1, PDK4, and HP genes was downregulated in SH and SHplus relative to control. Hepatic expression of NFKB1 was downregulated, whereas SOCS2 was upregulated, for SHplus compared with CTL.Implications and Applications: Despite the absence of treatment effects on productive variables, changes in blood profiles and hepatic expression of target genes were observed among treatments. These results suggest that the provision of shade combined with evaporative cooling was effective in alleviating the negative effects of heat stress.

Tough there have been great advances in estimating actual evapotranspiration, achieving accurate estimates at the field level
is still a challenge. The characterization of site specific characteristics influencing evapotranspiration like soil properties impose
a great challenge to the use of modeling, and the accurate characterization of the variability within a field of crop status may bias
estimates. Using remote sensing to estimate crop status and energy balance at a fine scale overcome some of these issues.
Nevertheless there is a need to have accurate and precise measurements of evapotranspiration that can serve as validation
sites. The eddy covariance method provides the accuracy and footprint necessary to be used as a reference. Two towers were
installed between 2010 and 2015 at two contrasting locations each year in the south-west of Uruguay at agricultural fields with
wheat-soybean crop rotation. The sites were maintained at the same location during wheat and soybean, and were moved
when other crops were planted at the site. Each tower had instruments to measure in parallel the energy balance (radiometers,
flux plates and soil temperature probes), and evapotranspiration directly from eddy covariance (sonic anemometer, IRGA). All
locations met fetch requirements, were representative of agricultural fields and were situated in an area dominated by agricultural
land. Season long totals showed large variability depending on crop status and seasonal precipitation regime that determined
crop growth and leaf area development. Even after full canopy cover was reached (maximum Kc) there was large variation in
evapotranspiration reflecting periods of severe stress in some years. This study provides reference values for a significant
number of growing conditions and years and highlights the need for considering the variability among years and crops when
making estimates of demand for supplemental irrigation. It also provides reference values for methods based on remote
sensing of evapotranspiration. MenosTough there have been great advances in estimating actual evapotranspiration, achieving accurate estimates at the field level
