Using 128 cm hip height for the cow, the shoulder height of the jaguar would be 69 cm (239 px/128 px * 128 cm) and body length 141 cm (264 px/239 px * 128 cm). I feel this too small and maybe we're underestimating the cow.

Great job, tysm! You're correct that I was understating the hip height based on that study, this can be confirmed by the paper PUBERTAD EN NOVILLAS Y TOROS BRAHMAN, Mendoza et al. 1999, here's a chart concerning calves of less than 1.5 years and the hip height is actually more than what I had previously posted (altura a la grupa):

At a weight of 320 kg those calves are significantly below the weight range of adult cows of 500 to 700 kg. I did find some information from some ranchers stating the rump height in Brahman cows is 155 cm, but nothing from peer-reviewed papers so I didn't include it here although I see very little reasons to doubt that information.

I did find better data, from Comparison of body measurements of beef cows of different breeds, Nagy et al. 2007

This is perfect because the live weights gathered for the cattle all fall within the Brahman cow range so we can use total average rump height instead which is 138.3 or 146.6 for a slightly above average specimen: in that case the jaguar SH would be ~75 cm based on the overall average or 79 cm based on the slightly higher average for the Blonde d’Aquitaine breed which seems the most similar in size, those measurements make more sense. For the fun of it, if we were to use the maximum rump height from this study of 158 cm assuming the cow in the picture represents a very large individual and close to the alleged rump height stated by the ranches for Brahman cows, the SH for the jaguar would be 85 cm.
