Hello everyone today. We have dr. Alan Chico from the Purdue University and he's gonna talk about South cooling strategies and with that. Thanks dr. Cheikh again for for your time here today. Welcome if you could, dr. Simcoe walk us through your background and your career so far before we jump into the technical aspect. Well, I grew up any more. Okay species now considered smaller Farm in Eastern, Iowa. Actually about three miles north of orcid ID exchange pigs cattle even had a few ducks and chickens and grew up doing 4-H went to Iowa State in animal sciences and then on and got a masters and PhD in genetics from University of Nebraska Nice. Been here at Purdue in extension research and teaching swine. I teach a 500 level genetics course, I teach wine production and I teach a one-credit 500 level swine growth model and class interesting. Yeah, very diverse. That's very cool. And so we have from from the South cooling strategy standpoint, do you have any idea and I know you mentioned previously that's a bit hard to to estimate the economic impact of hit stressing South. We have any we have any measures of that today? Well one estimate that I found heat stress in pigs in the United States total which include grown finish and South approach is about a billion dollars. Well on Outside it is a matter of how much the sounds are heat stress and under extreme heat stress. You can have an increased mortality rate right before during and after failing you'll have decreased intake decreased weaning weight and increase number of days. We need to have a stress smaller subsequent letter sizes and most producers know that they need to approximately. Ali double the size of their guilt pool when it starts getting in the upper 80s or 90s for some of the temperatures in time of farrowing time of breeding right because of the fairing rate reduction in rates going to go down. The number of sounds you can act in heat goes down the side of the guilt pool increases will be made in a lot of sounds with a lower conception rate. Subsequent letter, and then you'll be calling more sounds because you just don't detect them eat especially if it's a prolonged summer interesting very nice. So from you've been doing a lot of research on that that area of South cooling strategies. So I would be those latest strategies for cooling South. Okay. We have developed a cooling pad that is very effective at Cooling. In Val's, but other pads that have been developed in the past would use like steel pipes and put steel pipes in the concrete and it actually turns out you won't it cooling pad that has a low heat capacitance. It doesn't really stork eat but will transfer he excess heat from the south? Into the cooling water as efficiently and effectively as possible and the materials to transfer heat most efficiently are aluminum and copper interesting. We have a copper plate that is stamped on the top. So it's not smooth I try to play and then there's a patented thermal fin that attaches the copper pipes that's made out of aluminum. Hatches the copper pipe snap into but we can cool down valve depending upon the temperature using about a quarter of a liter to 3/4 of a liter of water per minute interesting where the where the water would be around 17 see come in if we on the more advanced pads that we just completed work on we go to electronic controls of flushing water. And you got to understand it first. We did a lot of what we call bench testing, but we had artificial to know which is about a 50 gallon tank of water on top of the pad with a rubberized kind of lower belly. And then we had a water heater that will heat the water at 37 to 38 C. And then we looked at different flushing. But if we if we can put either can have the It's flush on the set temperature of the base of the aluminum sheet or we can have kind of a control the timing of how often we flush the pads. But in that eighth, we let the water temperature rise the absorb the heat from the animal and then we flush and replace the water and the pipes hold about 1.75 liters of water. So we've got two liters of water if we use a plus Same Technique, we reduce the amount of water that's needed by another 50% And and if I recall correctly, you've seen a lot of change right from at least for a while respiratory rate and a few other things, right? Yes, and and I had a former student Francisco Cabazon was very self-motivated, but we took a lot of respiration rate. Skin temps and rectal temps and when we start a trial will have 12,000 maybe in this room and we'll go around every 20 minutes but we have heated rooms to 35 and sometimes if crept up to 36 C and the sounds are on the cooling pad at Point 6 .7 liters per minute are absolutely comfortable with respiration rate of 24 to 26 the sows not on cool. And Pad that's a control or control pairing crate at that same temperature for respiration rate around 10:00. And so we can actually with that seven tens of a Libra per minute, which is a very slow flow rate cool. The animal down is if it's absolutely terrible natural skin Town rectal temp and respiration rate if we up the water to about 1.1 1.2. Minute we can actually even over kill the animal even if the animal is at 30 60. Well, we did it once and put the pad at one point for the theater and the animal was moving from one side to the other side as it cooled down while side of its body to the other side of the body and so we can also estimate how much heat were removing. The pad is two-foot-wide 4 foot long a large how completely covers the pad. And we have the we know the inlet temperature we have from a couple in the water flow. We have the outlet temperature. We know the flow rate, but we have removed more than 550 watts of heat from the animal the animal the animal only is producing about 500 watts. So we actually can have an animal that is overheated and remove it lower its body. Sure by one one and a half degrees centigrade and then bring its respiration rate absolutely back down with in about 35 to 40 minutes time. Well now that 520 watts is more than four times that heat removal then can have with steel pipes in concrete far too because in concrete is just not an effective. For upkeep and so into the water. Did you do sobs Irv any change in feed intake or winning weight at all in our one Triad? We did we only had the animals he did the third 32 see here in the day and 27 see at night. We saw a 13% increase in feed intake. Well did that translate to anyway the other thing you have the other thing you have to remember? Is that the upper critical temperature true upper critical temperature of our modern sound that's nursing 14 pigs. It is right at 18 greasy and it may even be cooler than 18 see anyone that runs their firing house higher than 18 c is already Slappy overheating the South. So Al producers at the beginning of firing running their pairing house at twenty-three twenty-four twenty-five see That's ours the modern sound already overheated and and then of course in summer months when the room gets to be 25 26 and higher temperatures the animal is that additionally overheated right now. We have a team of people working on this heat stress physiology area from swine nutrition. Management point a reproductive and point heat stress physiology animal well-being standpoint and then we work with a USDA person Jay Johnson and we started doing work with indirect calorimetry with house but a typical sow on hot summer day by the time she's panting around 70 to 80 breath cemented as are reduced her heat production by at least 40 possibly. 50% wow now by the time she panting he's using energy to pant. So what what's happened? She sat down her digestion shunted blood to her skin and shut down milk production by 70 to 80% Oh, wow. So during the hottest part of the day the thousands of absolutely shut down milk production. And if you listen real close Pig suddenly, I am very hungry in the middle of the day. Hmm, then when it finally cools down later in the evening and at night the cells switch around their feed intake eat more at night and start producing more milk and using it then so we've quickly realize that the sounds are very Dynamic and once the cell starts overheating you see a cell panting at 60 70 80 breaths amended. She already has substantially decreased her milk production at that specific moment in time. Very interesting. Well, did you see changing when you weight or or not? Oh, yes. Okay. We the last small trial we had we saw both a 13% saying he didn't take and 13 percent increase in many ways. Oh, wow, the other people that had the cooling path with the steel pipes. Concrete also saw those tired of advantages even though they're the hottest part of the day. They have two rooms two was 28 see mmm. So we've not done any research. They'll smack dab in the middle of the summer, but we think that with the cooling path essentially we would have the same feed in tanks and same Wing weights that you would have if this how was absolutely Thermal neutral well, so can is it available today for for producers or not yet? What's the status of them help you have we have sign and number of NDA with companies who want to manufacture them by the hundreds? Hmm and then once those pads are getting built by the hundreds and by the thousands then we will be running as bir Grant and Doing trials to show their use on we call beta testing swine farms and we have a number of swine Farms the raised their hand and said that we want to want to be the first ones to have them and we would probably, you know do a farm in Indiana and new a farm in Oklahoma and do a farm in North Carolina kind of situation. Mmm well and and then look there change in performance over. You know over a year period of time very nice. Is it so are we talking here in the next year or so or more in the next year or so? Okay and Purdue owns the patents and the biggest thing slowing it down is discussion between lawyers. Okay, unsurprisingly, very good. Um, wow anything else on this topic? So she can go from cooling strategies specifically or in general as well anything that you recommend today as well for producers and there is one thing that that is kind of a struggle here. It's that with our increased litter size the baby pigs won't burn warmer and producers. Some of them are looking at what can we keep the pairing house 72 degrees or 73 degrees or 74 degrees and that's becoming increasingly. Increasingly too warm for the South and there are papers the modern Sal today produces 55 to 70 percent more heat than the cell did of the mid-1980s and whether it's highly engaging pigs and grow finish or its high milk production in South growth and milk production produces heat now the Ed next areas that we're going to be starting to do. search on its butt doctor caressed work and we're going in Jay Jonathan again with the heat stress physiologist will be gestating gilts and sows that are just bad at about a hundred twenty five percent maintenance and then also doing trials for boars at 32 C and 35c and then we will expose the animals to heat and the boers it will be a matter then of looking at their semen quality out the first seven weeks after the heat stress. Hmm interesting. And is that that one happening next year that will be happening in next year. In fact, the first week in January will be doing the gestation guilts and will quickly look at that data. And look at what if the optimal cooling for an animal that's being fed, you know at 350 pounds 125% maintenance and then make a decision. What's going to be the optimal strategy for the bars, but with the boars, it's a matter. Once your heat, press them you affect their semen satin weeks out. So you have to heat stress and measure their semen over seven weeks reassignment treatments and do it again. That makes sense. Very nice celebrating its 25th anniversary just all manufactures the original Wireless Standalone swine feeding system designed by pork producers for pork producers. They are simple reliable and provide Peace of Mind 24 hours a day 7 days a week 365 days a year just stall is not just manufactured by an equipment company, but by a family pork production business with a slat Understanding just all always one step ahead in swine feeding. It is time to our famous. I guess we can transition to two or three questions. Dr. Shankar that we ask every guest every episode. And the first one is what's your favorite swine related book? I would have to say it's NRC 2012, but some of the data in there as far as the growth curves ractopamine curves is my head. But the use that as my textbook for the one credit graduate level swine growth modeling and nutritional requirements, of course, they teach nice very good. Yeah, I love the NRC as well. Okay, and then how about a book or resource in general outside of peak production? Well, I would say I'm going to study the Bible and and that's been lifelong and then I Another book that I liked that was given to me by the author as she came and talked and spoke to one of our pork interest group meetings, but it's no more food fights. It's by Michelle Payne Cano / and it's a book on how in current agriculture. We need to defend current livestock production. Mmm-hmm and And how we're going to have to take a more active role in defending livestock production in the United States, right? That is interesting. I was not aware of that book. That book is copyrighted 2013 very good. And then the last question is what separates a successful sewing professionals from those that are not in your opinion. Well successful swine professional an attitude of being a little bit open-minded of being willing to continue to learn to accept that pigs change people change and I think that another successful thing is the art of being a soft skills of working with people and being a I would call a maybe a soft leader and you listen to people Gain, the respect of people and you lead about you know necessarily an Iron Fist and in your authority to actually really interacting with people interesting very very good. Now that that makes total sense type of leadership. Very nice. Very good. I appreciate your time. Dr. Simcoe. It's been a pleasure having you in the in the podcast and you know discuss about this very important topic of trying to cool ourselves in in the summer and also in some areas of the globe.

Today’s episode will cover “Sow cooling strategies”. “The true upper critical temperature of our modern sow nursing 14 pigs it is right at 18oC, and it may be cooler than 18oC. Anyone that runs their farrowing house hotter than 18oC is already overheating the sow.” – Dr. Allan Schinckel. Our guest is Dr. Allan Schinckel. Dr. Schinckel is a faculty member in the Animal Science Department at Purdue University. He received a B.S. in Animal Science from Iowa State University and a M.S. and Ph.D. in Quantitative Genetics from the University of Nebraska, Lincoln. His research interests include lean growth modeling, pork quality, repartitioning agents, and methods to predict carcass composition and value. Dr. Schinckel has collaborated on numerous swine research projects, including production systems, environmental effects on pig growth, food safety, growth promotants, and biological markers of disease and stress. What you will learn:   The economic estimate of heat stress in sows;  The latest strategies for cooling sows;   What can be implemented today;   What separates successful swine professionals from those that are not.
