Deer Haven Farm :
Same herd (1/2 mine half my parents) same bull. I had all heifers and the they had all bulls. Every one of these cows were born on our farm. All born within the same 6 wk window

So what about boy/girl twins. We had our first set of twin this year. I mean we did tell her that since her pasture partner wasnt having a calf it would be great if she had two. 😂

We see the exact opposite in our sheep. When the nutrition is poor or drought like conditions, we end up with more ram lambs the next season. When the nutrition is good with lots of rain and fresh grass the season before we end up with a ton of ewe lambs. My theory has been for a long time that when there is enough high quality forage over a season, they tend to pop off females the next season because more lambs can then be supported. It tracks with most biological theories on population density expansion. More resources equals more potential for reproduction. However, Trivers Willard makes sense too because it accounts for the need to have more daughters to produce more offspring later because there is a likelihood those offspring will in poor conditions. The more females you have that have offspring, the more likelihood that you will have some offspring survive within that total population. What we have to keep in mind is that agriculture truly is an artificial population instead of a natural one, and therefore a lot of the biological theories are hit or miss in their actual observation. So essentially something that can be proven in the wild to be true, may not necessarily be observable with reliability within an agricultural setting.

Have never heard of this...but explains why I'm am so lucky to have my first 9 out of 10 babies be bulls! Most of my mommas are retired show heifers that we have raised...so yes, spoiled, low stressed, high maintenance heifers have bull calves!!

I have a cow about 10 yo who has NEVER had a bull calf. Had another who only had bull calves.

Kurt Loseke :
In my small herd I have exactly the opposite. My cows are typically high condition scores and over the last 15 years I am heavy on heifers with only one or two exceptions. Different bull each year. My theory is that nature sees the cows have plenty of nutrition so nature increases the herd with females.

Georgia :
NO WAY.. I saw the pattern when id dry lot cows to breed.. I'd get more heifers vs what was conceived on grass.. id been saying that stressed cows have more heifers.. had no idea this was a thing

starbocj :
another thing to consider is at what stage of heat does she get bred. earlier in heat cycle the egg is farther away and the x sperm can last and go farther in. the y sperms are faster but burn up faster but if the cow is later in cycle the y sperms gets to it first. I have a couple cows that the only way we get heifer calves from is to AI them. every calf produced by the herd bulls have been bull calves.

Makes sense as a biological survival tool for the species. Stressed animals creates more females to help keep the population balanced for the species

KyMarie :
The temperature outside will also reduce the amount of male sperm produced. Same for humans, if the nuggs are too hot, the male sperm count is reduced. We've noticed this with hot spring vs cooler spring. Bulls health is important too. Their count is based off of what happened on a "3 months ago" scenario. If they were stressed, sick or otherwise, their sperm quality is reduced.

Joseph Schneider :
My theory is it’s more about timing. That determines the gender. Earlier in there cycle they get bred the more likely hood of having a girl. later in the cycle it’s more likely to be a boy. I think there’s an evolutionary advantage to this being if she gets bred early it means there’s more bulls around to take care of breeding. If it’s later it means there’s not enough bulls around.

This has been scientifically proven in humans, the first sperm to the egg is not always allowed to embed in the egg. The egg determines which sperm is allowed entry to create life

Fat Cow Ranch :
Fascinating… But at what cost. just for couple more bull calves?

There is a whole book about this "Choosing The Sex Of Your Baby" my OB told me to read it over 30 years ago when I joked about wanting a girl baby after already having a son. She said that the dairy industry spent millions learning how to increase the ratio of female dairy cows. The science made complete sense. It worked, got my girl for baby #2. It was mostly about predicting ovulation and timing sex to increase the probability of having the desired X or Y sperm arrive at the just the right time during the ovulation process.

I've noticed (and seen folks talk about this) that if everything is good to go... if you breed in the cool or winter months, you get more heifers. Breeding in hot months... you get more bull calves.
