2 more articles in press at JDS about spray timing

11/17/2018

For those of you that don't follow my work, I have spent a great part of my PhD understanding how the spray (sprinkler/soaker) timing (i.e., on and off times) affect cow cooling and its effectiveness. After spending some time around drylots in the Central Valley of California, I had a feeling that timing could affect how cows use the spray. I tried to replicate that in a tiny freestall but it did not work the way I expected (and I have some guesses why).

In summary: when spraying cows the SAME amount of water but using different timing strategies (more or less often) we did not see any biologically relevant effects on cooling. On the other hand, when spraying cows for longer or reducing the off times (thus, using more water), cooling benefits were more pronounced in comparison to strategies that used less water. These last findings were not novel, however, I'm very proud that I provided outstanding cooling for my cows. None of the papers published before achieved such cooling levels!

With these 2 papers in press, I have published all my dissertation work - yay!

BIG NEWS:

I am so excited to tell you all that I have started my work as Assistant Professor at the College of Agriculture - California State University, Chico. I hope to greatly contribute to the education of the next generations of ag-professionals and to engage on cattle welfare research. Much moooooore to come!

Another paper published at JDS!

Great news! I had another manuscript accepted for publication at Journal of Dairy Science!
In this study, I found that:
  • cooling benefits were more pronounced when water was sprayed for longer (time on)
  • spray duration had little biological effect on time it took the coat to dry, and no cooling was observed in this phase, except on windier days (time off)

In this heat-stress assessment we conducted in commercial drylot farms in California, we found that during the afternoon dairies could use a lot of potable water (we estimated over 150,000 L per 1,000 cows during the afternoon) and that  (individual) respiration rates could range from 25 to 150 breaths/min.

These results prompted me to pursue other scientific questions I addressed during my PhD:
1. How can we identify dairy cattle experiencing high heat load?
2. How can we optimize cooling strategies for lactating cows?

Dairy Cattle Welfare Symposium and more!

7/13/2017

At beginning of June I was invited to present some of my PhD research at the 2nd Dairy Cattle Welfare Symposium in Wisconsin. I shared the grad student panel with other colleagues from a range of Universities in North America, including my long term friend and colleague Catalina Medrano-Galarza who's a calf expert. The symposium was full of good conversations.

Next, I'll be travelling to Puerto Rico and Denmark, so more news coming soon!

​I have great news to share about my pictures!

​​I had my first photo show two Fridays ago at the Putah Creek Winery in Davis CA. My pictures will be shown at their tasting room for more two or three weeks.

​Come see it! :)

​In September 1st 17, my first cover book picture will be published: Advances in Cattle Welfare. 

​Couldn't be better!
PS: I also got a paper almost accepted! :D

Love talking about my career choices!

Last Tuesday (Jan 31st) I had the opportunity to talk again about my career choices with UC Davis undergraduate students part of the Pre-vet students supporting diversity club. The objective of my spill was to encourage students to also seek careers beyond Vet Med, especially research.
​Professors from the Department of Animal Science Drs. Russ Hovey, Ermias Kebreab, Matthias Hess, Anne Todgham, and grad student Ryane Logsdon (Animal Behavior) were also sharing their experience with students.

Sustainable cows @ EPIC Symposium

On Dec 1st I spoke about cows to a less usual crowd: a bunch of stakeholders and other experts on energy efficiency, renewables, and smart grid technologies - at the EPIC Symposium hosted by the California Energy Commission.

I joined Theresa Pistochini from the Western Cooling Efficiency Center (UC Davis) to talk about our project "Improving water and energy efficiency in California dairy industry" that aims to find more sustainable solutions to cool cattle in CA (the presentation can be accessed here). We shared our section with Dr. Larry Dale (Lawrence Berkeley National Laboratory), Laurie Park (Water Energy Innovations) and Dr. Joon Min (BKT), who also emphasize the importance of water and its impacts in CA. 

EPIC is an energy innovation funding program that seeks to drive efficient, coordinated investment in new and emerging energy solutions. The Symposium highlighted innovative solutions for reaching California’s 2030 energy goals. I am proud to be part of that!
