He said that he recalls them saying they were a bit smaller than the Pantanal ones but he said he'd speak with them about it again and get back to me. I'll relay what he says once he does.

The article, in Spanish which is good, mention the weight but not the length, maybe in page 79 (like the article says) is more information. Thank you for share this.

Are the weight of these 120 130 kilos ounces on an empty stomach?
are the jaguars of the Atlantic forests shown here on an empty stomach? 
As I promised Its finally here the study on the average size on cerrado male jags compared to cerrado male puma.

LEANDRO SILVEIRA Guidance. Prof. Dr. Jader Marinho Filho THESIS PRESENTED TO THE POST-GRADUATE PROGRAM IN ANIMAL BIOLOGY AT UNIVERSITY OF BRASÍLIA ( BRAZIL ) AS PART OF THE REQUIREMENTS FOR OBTAINING PhD IN ANIMAL BIOLOGY. BRASÍLIA D.F JANUARY 2004 UNVEILING The Cerrado male Jaguar's average weight/size. Average Cerrado male jaguar in comparison to average Cerrado male Puma. Before talking about the average size of a Cerrado male Jag and Puma, let's first see the size of its preys in comparison to the cerrado male Puma's preys as well. obtained by summing the products of individual items of prey with their weight, transforming in logarithmic scale ( Log-N ), divided by the total number of prey used in the analysis ( Iruate et al., 1990 ). for the peccaries species ( Tayassu pecari ) were considered different weight measures when treated for the cerrado jaguar and puma, assuming that the former species most commonly predate adult individuals ( 40kg ) and the latter, young individuals ( 5-25kg ). Collection of analyses of carcasses of prey slaughtered by Jags-Pumas. carcasses of prey slaughtered by the cerrado jaguar and puma were located in the field during the monitoring of radio collared animals. usually clusters of vultures served as an indication of recently slaughtered animals. For the identification of the predator, tracks were sought in the environment, since the format and measures are different for each species ( Aranda 1994 ). when not found, the carcass was analyzed for evidence characteristic of each predator. for example: jaguars can kill animals the size of an adult tapir ( 300kg ) in addition to anteaters and peccaries. The site of the fatal bite is usually concentrated in the upper region of the neck, the average distance between the canine marks on the bones is 37 mm and they usually starts the consumption of the carcass by the pectoral region, jags do not cover the carcass however they can drag it up to 1000 meters ( Crashaw & Quigley, 2002, personal observation ). On the other hand evidences of predation by pumas are characterized by the slaughter of medium sized animals such as peccary ( Pecari tajacu ), armadillos and terrestrial birds such as rheas and tinamids, the fatal bite is generally concentrated in the lower part of the neck. Pumas start the consumption of the carcass by the abdominal region, the average distance between the canine marks in the bones is 26 mm, they have the behavior of covering the carcass with foliage and sticks For analysis of regurgitated cerrado jaguars collected, the samples were taken inside a sieve under running water. subsequently their content (usually hair and bones) was identified through a reference collection. this sample category (regurgitated) was analyzed together with the carcass category, since it necessarily corresponds to a single meal. RESULTS Characterization of the Species Cerrado Jaguar and Puma Of the four cerrado jaguar individuals captured in Emas National Park (PNE), two were male allowing comparison of animal weights from other locations (table 1). In relation to jaguars both considering the average weight of males and females together, and considering the average weight of males, the animals from the PNE stand out as the largest. Male Pumas represent approximately 60% of the weight of male jaguars and differ significantly for three measurements: weight, head-body length and thorax circumference. Seven pumas ( four males and three females ) were captured in the region of the emus park and their average weights are in table 2. Adult puma females in the ENP have a weight corresponding to approximately 57.5% of the weight of adult males of the same species.

Cerrado jag - I wish there was adult female cerrado jags sizes here since we already know the male's size potential  Pantanal jag - Female pantanal jag's average of 76 kilos is more clear than crystal water. - About the pantanal male jags. today they're doing far better. I AM SORRY ABOUT ALL THESE ADVERTISEMENTS. 
Attention: For those who couldn't see the tables well of the weights, measurements and other details on the 2 posts above, I would like to recommend you guys to see the tables on the computer, through the computer it displays the tables much better than cellphones/mobiles or you can see through the links and pages I posted.
With that being said. Let's go. Credits: https:// empty.com.br/ Gisele female from southern Pantanal captured by Onçafari. 90 kilos. https://empty.com.br/blog/conservacao-da-onca-pintada/ This time a 90 kg female was captured with the loop technique, which consists of camouflaging a system on the ground that causes the jaguar to step on and be caught by the paw. Gisele as she was called received a GPS necklace via satellite, which sends the signals through the internet and allows the teacher to monitor the animal's steps from her computer in Tubarão. The GPS necklace remains on the jaguar for a year and a half, time when the project's technicians map the jaguar in order to know which places it uses the most. Blood and tick samples were collected from the animal. The blood was sent to the different laboratories associated with the project: the samples are stored in the genomic bank of the National Center for Research and Conservation of Carnivorous Mammals (Cenap-ICMBio) in Atibaia, at the University of São Paulo (USP) and at Unisul de Tubarão. The results are used both for basic research of jaguars and to accompany the process of accustoming animals to tourism.  *This image is copyright of its original author

This confirms that we have no data on Llanos jaguars regarding their weight, height, and length and will continue to rely on pictures to get an idea of how big they get. Yes, Edu luckily spoke with their Vet who wrote this "I asked to our vet about the jaguar at La Aurora and he told me they are smaller than in the Pantanal although the landscape is very similar" "I'm still waiting for the exactly weights of the jaguars there" "An adult male jaguar weighed 93 kg there" When I asked about his measurements "No, he just told me that the jaguar was full grown male. The vet doesn't get the measurements information" Feel free to ask Edu about it as well, he's open to conversation. https://www.instagram.com/edu.fragoso_/

The soon to be King of Jaguars, Mercury. His dad, Sol, is the biggest Jaguar that we have. He weighs around 90 kilos (198 pounds) and Mercury is almost as big as his dad, but not even 2 years old. For sure that he’ll be bigger. Look at how massive my grandson is. And beyond gorgeous of course. Look at the size of his head and forehead...

Impressive, I didn't expect it from that particular jaguar, he also was not dwarfed in size by the lion next door, they looked rather similar in size from that perspective.

An ounce swallows 15 20 kilos of meat will present a large weight even if it is smaller. Example an ounce of 70 pounds eating 20 pounds of meat will result in weighing in at 90 pounds. If you weigh 90 it will result in weighing 110 kilos. The contents of the stomach should be assessed by the extent of the abdomen as is done with leopards.

Its done with Jaguars, Almeida noted stomach content and Hoogesteijin has done so as well. Oncafari has done so on a few of their cats but Jaguars are hard to tell if they're full or not since they look bulky regardless. It's also a moot point since all cats generally have some content. |
