Thanks for the info @Big_D, I did find the info but they advised using yoked barrier and scraping at the back. But your design suits my building better and I would assume is an improvement on the original design.
I was going to try compost bed with chopped brash but that big company down your way working on my neighbouring farm messed me about something chronic , i orderd 800 cubic meters at the price they wanted and never phoned back never delivered anything , got straw in the end again as it dropped in price back to realistic level .I guess your on a much drier climate than me @Kiwi Pete, mine would a sloder hole on that system I fear
Looking forward to it !Well as promised I will be starting a new thread to show the alterations and building phase of my sloping floor experiment. Once completed I will continue posting updates through the winter to show how the cattle are performing on it and any savings in bedding etc.
OT
This year, being understocked over winter, I basically rotationally grazed in my shed, always had two pens empty, and it dries out because the microbes keep it so warm.I guess your on a much drier climate than me @Kiwi Pete, mine would a sloder hole on that system I fear
Do you go through it with a triple k ? ones i have seen on youtube they tripple k them twice a day to keep air in .This year, being understocked over winter, I basically rotationally grazed in my shed, always had two pens empty, and it dries out because the microbes keep it so warm.
If you dig your hand in it is about as warm as you'd run a baby's bath, about 30° or so.
As you'd imagine, that helps keep the costs minimal, quite a saving in feed alone before you factor in the savings on ill-thrift and vet bills
I may have mentioned the cattle eat a fair bit of seaweed in chopped and liquid form, as well as about a ton of charcoal (homemade stuff) which helps prevent methane and ammonia losses - and means it's a living thing, more like a good soil than simply a bedding medium.
Most visitors are bracing themselves for an awful stink when they walk in, and comment that "it smells like a freshly ploughed field"
I don't use straw, it's wrong for what I want, we use about 15 bales of peastraw right at the end and that buggers it up for housing (as the moisture is trapped in)
however a few pigs soon get it broken up
How deep is it ?This has been an exceptionally dry year.
We had cattle in it in the summer as well, but normally every day is some fraction of wet over winter or they wouldn't be in
Good drainage and ventilation is absolutely critical, you don't absorb much with woodchip so you could run into trouble
however we have a serious depth and fall in the middle and the valleys are deeper chip, on a layer of sand with drain in although the bottom 2 thirds of the chip is dry enough to light it with a cigarette lighter if you fill it in good time.
I have a few bits of string that run the condensation into the water troughs as the double tunnel does have a lot of condensation and it dripped off the centre valley and made a wet line.. that part is actually where the old sheep race was when the site was sheepyards
But apart from being able to keep cattle cheaply and have your compost started inside where you can add what you want to it, not a huge number of downsides really.
We have had 23,000 cow grazing days on $1446 of woodchips, and added an optional $1200 worth of peastraw to it, literally cheap as dirt.
I have curtains on one end and the air comes through the gratings in the shearing shed if cold, open a big door if hot, it gets hot very fast if you don't have airflow, enough to kill my pumpkins.
Just been out shooting possums and rabbits with old mate
In the shallowest parts about 14 inches, up to just over 3 feet where the drains are.How deep is it ?
