Hello! Total newbie here, and just acquired a small herd of Black Angus cattle with the purchase of our new home/farm a couple of months ago; I tend to be an over-worrier, but my question/concern is for a 4-5 day old bull calf and whether he’s nursing enough in the TX summer heat

within the first 24 hrs after birth, once we noticed his arrival, we watched closely and decided he was not attempting to nurse, became very weak and lethargic that evening and we brought him in to syringe feed colostrum mixture throughout the night; by the next morning he was up and moving and looking to nurse, yay! Then fast forward a couple days later, in the heat of the day, I noticed him stressing out trying to figure out how to go down and around this partial fence to get to mama, and by that point he was open mouth panting, looked weak and exhausted, and once with mom was not nursing; after some more observing I decided to give him some more formula mix for hydration and after some rest he was up and moving again, but now today, the day after, he’s been under a shady tree line all day and has not nursed for the past five hours and mom and herd are on other side of pasture again; question is should I intervene again? He’s cool to the touch, slightly panting but closed mouth, sleepy, doesn’t look to be in distress, but is this just normal activity or is he not nursing enough in this heat to stay hydrated and well?? Thanks for reading, and any advice appreciated. Thanks!
