In each drought cycle some producers have an earlier finish to the drought than others and a few are extra severely affected by drought than others. As producers liquidate productive cows resulting from drought, there’s alternative to ship in cows with prime quality genetics that in any other case could be within the prime of their productive life. However typically these cows have been held on to for too lengthy by a producer ready for the “ranch saving rain” that by no means materialized, with too little grass and little to no hay or feed in reserve. It’s arduous to show free of genetics we now have been constructing and dealing towards for years, so you’ll be able to perceive the thought course of, nonetheless these cows have turn out to be a lot too skinny and weak to outlive a extreme climate occasion, not to mention be productive. Nevertheless, with the best administration, these cows is usually a huge profit in constructing a cowherd on your future, or a windfall for brief time period achieve if bought when the market correction happens (it at all times does).
There are explanation why these cattle are low cost:
Skinny cows have much less chilly tolerance
Cows in good situation can stand up to temperatures beneath 32°F fairly nicely, skinny cows with skinny haircoat could have a decrease important temperature of round 40°F. For each diploma beneath the decrease important temperature vitality necessities improve by 1%. A winter storm hitting skinny cows with little safety is usually a catastrophe. Dana Zook and I lined feeding cows by chilly climate occasions within the Cow Calf Nook Publication from December 19, 2022 check with https://extension.okstate.edu/applications/beef-extension/cow-calf-corner-the-newsletter-archives/2022/december-19-2022.html for extra particulars.
Skinny cows have extra issues calving
That is very true for heifers. It takes quite a lot of vitality to expel a fetus and infrequently new heifers run out of energy earlier than the method is even getting going. If we take too dramatic steps to enhance the situation of the cow, we will affect the dimensions of the calf. My rule of thumb is over diet on a 3rd trimester cow can improve the calf weight by 10%. This isn’t normally an issue for a mature cow or a well-developed heifer in good situation. A ten-pound heavier calf will be catastrophe for a 750-pound weak skinny heifer.
Skinny cows have weaker calves
Calves born from assisted births are normally weaker and take longer to rise up and begin nursing. Each the cow and the calf are exhausted. It will delay the uptake of colostrum, which has big results on well being and resilience of the calf. Undernutrition throughout fetal growth limits manufacturing of fats within the calf, particularly the important brown adipose tissue wanted for fast vitality early in life. If calving occurs throughout a chilly winter storm the calf could wind up laying within the chilly wind and freezing to demise.
Skinny cows produce much less (and weaker) colostrum
As talked about above colostrum is important for early passive immunity switch from the cow to the calf. Maternal antibodies in our analysis typically are nonetheless discovered within the calf for as much as 4 months. Calves that get restricted or no colostrum shortly after delivery are much less resilient to illness extra more likely to succumb to scours or respiratory illness earlier than weaning and have extra well being points all through manufacturing.

Skinny cows have issues rebreeding
Analysis at OSU from the 80’s and 90’s has proven us the significance of physique situation at calving on post-partum interval and rebreeding success. Cows in BCS 3 have been proven to have 20-day longer post-partum interval and 20% decrease being pregnant proportion than cow in BCS 5 (90-days to first breeding vs 60 and 60% being pregnant vs 80%). Cows that wanted help throughout calving even have decrease rebreeding percentages.
Cows calving in skinny physique situation have additionally been proven to have improved being pregnant charges when they’re growing in physique situation earlier than breeding. Growing physique situation throughout lactation just isn’t simple and is dear due to giant will increase in protein and vitality necessities, however it may be finished in the best conditions.

Savvy operators can handle by these challenges and have profitable outcomes with these difficult units of cows. Having a clear calving pasture with loads of cowl from the climate that’s helpful to the working services is a should. Including flesh to skinny cows post-calving just isn’t simply finished utilizing hay and complement. We’ve got had a lot larger success placing younger pairs on prime quality wheat pasture or restrict feeding a excessive focus TMR to cows than attempting to complement together with even good high quality hay.
