My biggest take home message to people is always to look at what wild animals do versus livestock. How they live and how much they produce, whether it’s eggs or meat or milk.
Wild hogs is a great example because hog farming is so huge.
"The average adult body weight of a feral hog is approximately 180 lb. Males are slightly bigger, with the comparable body weights for adults of each sex as follows: 150-170 lb for females, and 200-220 lb for males. Exceptional specimens have been reported to exceed 500 lb. In most instances of these exceptional weights, the animals were males. "
So that’s for 2 year old or older feral hogs. Modern pigs outgrow them super fast and have significantly more muscling that has been selected for to get us the cuts we like.
"Reproduction in feral hog populations can occur during any month, with both sows and boars being capable of breeding year-round (Fig. 2). Typically there are 1-2 seasonal peaks in breeding. However, annual patterns with one or two seasonal peaks can occur within the same population, varying from year to year. Regional photo-period, rainfall and nutrition all influence the breeding season in a feral hog population. Feral sows are capable of producing more than one litter per year. The production of a second litter was observed to be common when sows lost the entire first litters; however, sows have been breeding while still nursing a litter of piglets. Normally, sows do not conceive when still nursing a litter of piglets. In eastern Tennessee, numerous wild sows were observed to have bred within a month of farrowing, however, very seldom did these females conceive. In addition, when these sows did conceive, only very small litters were produced. "
Modern pig farming is down to the day. It is planned what day they get bred or AIed. What day they move to farrowing crate. What day they birth. What day the piglets are weaned. What day the piglets are sent to another barn to be raised. What day they move to the finishing barn. What day they will be shipped to the butcher and what they should weigh.
It’s clocked so tightly that they have a day or two to empty and sanitize the whole barn before the next truckload of piglets comes in.
This is why during the beginning of the ahem illness that shall not be named… Why farmers were selling half raised hogs for $20. Why entire barns of animals were put down. Because it’s on a schedule and that doesn’t include them not being able to take the current barn load of hogs to the processor. Now the entire system is stopped. And more sows are about to birth because they were already bred almost four months ago. And there is a succession of sows bred to birth after them, and after them,…
This is in very stark contrast to wild animals that have one or two litter a year and many of those die off before reproducing.
I hope this doesn’t read as a rant, I just know that most people aren’t aware of how this works or just how wide the gap is between modern livestock and wild animals. But it is extremely important to know if you are going to think about raising any animal.
