Today’s (June 19) chores were frustrating and exhausting – hopefully, i won’t vent too much, but instead methodically record what happened and what decisions to make based on the mishaps. However, the first of the morning was spent walking in 3 Angus heifers to attach Estrotect patches in preparation for AI (artificial insemination) over the next weeks followed by spraying off 30 gallons of Surmount chemical mix on woody brush at my farm. Started about 5:30 am.
This late spring I started letting my cows graze the new seeding implemented last fall. It’s been super, super dry (until today! already 8/10s of an inch and still gently raining), so using a back fence was not important since the grass wasn’t trying to grow back after grazing because of the heat and dry.
Nevertheless, I’ve been stripping off sections of about 2 days grazing each – no where near what could be considered mob grazing, but i’ve already decided that is a practice which simply won’t work for me. I had already set up 2 temporary fences of polybraid of about 1/4 mile each. Anyone who has done this realizes that that 1/4 mile of walking turns into at least a mile by the time the poly is unrolled, then walk back to get posts, then set up posts along the poly and hook the handle into a hot (electrified) lead.
When i arrived this morning, the cows had blasted through both of them!! I was not a happy camper to say the least. Thankfully, i had brought along another 1/4 mile roll of poly braid and I pushed the cows sort of back where they belong and i unrolled this tape. The grass and weeds were tall, so it just sort of laid on top and looked like a fence the cows didn’t want to bother. Testing the lead, i found that there was no electricity. Ah ha! all the polybraids were ‘dead’ and with baby calves running around, it didn’t take long for them to run through with mommas right behind.
But why was the fence dead?
I had spent some time at that very spot repairing some wire and gate just 24 hours before. Why did the tree not fall while i was there? Only by the grace of God. Not only that, but my spinning jenny was unharmed and the end post was still in place! Only one gate handle and the top hi-tensile wire was busted. Easily repaired that. Plus, the tree fell in such fashion that i didn’t even have to move it or cut it up. (thank goodness because i didn’t have my chainsaw on this trip). I simply repaired around it. It will have to be removed when i have time.
But this also is a prime illustration as to why forests, timbers, draws, need managing! Treehuggers take me to task for removing mature and junk trees. But without management, trees can become diseased, can’t compete for sunlight and nutrients so they can die and are a major hazard.
Anyway, back to my morning winding up. Once all was said and done, i’d walked at least 5 miles in tall forage, scratched through dense brush, and crawled in and out of deep ditches to retrieve all my temporary fencing and posts, finishing the morning installing a new rain gauge, checking my replacement heifers, and resetting an end post.
Dragging back to the seed plant, refueling the JD Gator and using forced air spraying out the seed heads from the grill (this must be done to keep the Gator from overheating), unloading the reels of polybraid and a bunch of posts. I forgot to take water with me and by noon (got home), i had lost 4.2 lbs. Goodness, that is 1/2 gallon of water sweated out!
This was another reminder of why mob grazing with multiple shifts per day will not fit with my schedule and quality of lifestyle. It’s just too stinking much work – i sold off the sheep to get away from so much exhausting work. With tall grass (not complaining), deep ditches, long stretches of temporary fencing, dense brush, and baby calves not trained to electric braid, there are simply too many bugaboos to make this a happy time. The mob currently has about 20 acres to relax and graze. It is what it is – i do the best i can.
Weather was nearly perfect this morning – a welcome relief from the 90 plus temps and high humidity. May have been the most beautiful day since last November!
This is my viewshed whilst shifting cows to a new paddock. Okay, actually they shift themselves – i really don’t do much with the cows most of the year.
About a week ago, despite our poor pasture growing situation due to dry and hot weather, i tried what others have done and that is UHDG or ultra high stock density grazing. There are some who have successfully managed shifting cows 5,7,9 times a day and obtaining up to 1 million pounds of livestock per acre! That can result in a phenomenal improvement in soil quality due to deep rooted plants and evenly distributed manure.
My experience was far different and after a couple of hours quickly realised my misgivings as to mob grazing’s effectiveness in our area.
Putting dollars to that extra growth: In normal and decent growing conditions (not over 90F and normal rainfall), cool season grasses and legumes could potential produce 8-12 inches of growth in 36 days. An average pasture with little to no bare ground (spaces between plants) might yield 300 lbs to the inch per acre. So, if the entire farm received that additional 36 day rest, then 400 acres x 300 lbs per inch x 8 inches growth = 960,000 additional lbs produced. Reduce that by 20% to get a hay equivalency and price it at 5 cents per pound, then 768,000 lbs x .05 = $38,400 worth of hay that is not needed to purchase and maintain or grow the herd. OR, consider that as my wages for setting up and taking down posts and polybraid during the summer. Of course, nothing is perfect or normal, so even these conservative figures may fall way short in the face of a drought or hot temperatures. Nevertheless, there is gain to be considered IF the labor does not become cumbersome and cost more than the value of forage.
Well, this was all written on Monday the 21st of May – a week later – still no rain and temps continue well into the 90s with heat indices above 100 for several hours each day and little to no wind. It’s muggy and hot; cool season pastures are no longer growing, so the planned grazing is relaxed already since the cows need shade and i’ve set up a paddock with a big timber patch. Guess where most of the manure (nutrients) will end up? Yeah, not where planned. As usual, theories, plans, scenarios all go out the window in the face of nature. Like any other year, we just do the best we can with the conditions we are given.
Today marked the last day of my experiment with rotatilling, pneumatic drilling/harrowing, and grazing annuals as part of a pasture improvement scheme.
Grazing comparison data is as follows:
2013-2014 – Paddock 22 – 3218 lbs, Paddock 23 – 1871 lbs Total: 5089 lbs
2014-2015 – Paddock 22 – 3567 lbs, Paddock 23 – 2007 lbs Total: 5574 lbs
2015-2016 – Paddock 22 – 2072 lbs, Paddock 23 – 1222 lbs Total: 3294 lbs
2016-2017 – lost all my records
2017-2018 – Paddock 22 – 1547 lbs, Paddock 23 – 695 lbs Total: 2242 lbs
As you can imagine, i was shocked at the lack of grazing days provided by the annuals, but this was my first experience. When i turned them in on the annuals, the cows and calves grazed it all down in four days! In a few days, i was able to turn them back in for a couple more days grazing to boost that yield just a bit. However, at this point, the paddocks will take a very long rest. One thing i did not observe and record in previous years and that is cow condition. At least for this year, these cows were slick and shiny healthy coming off the annuals, but they were that way going in, too. So…..
So, in a nutshell, it cost me a total of $1842.12 to plant 18 acres of annuals for grazing. The purpose of annuals to help rejuvenate the soil microbe community and not necessarily for gain in grazing. Good thing, because it certainly failed in that department. However, as i had written before, the goal is to eradicate toxic fescue and build organic matter. It does look like that has happened at least in short term. It is very hard to measure long term benefits. However, from this point, i’m planning to tack the sail and switch to tilling then no-till a permanent ley (grassland). Whether or not that will work remains to be seen, but i’m keen to find a way to reduce then eliminate any tractor work. I hope to get that scheme underway and perhaps even completed this week. This new scheme, although i do plan to till before planting to permanent ley, will provide a side by side comparison of planting annuals first vs planting permanent pasture once and done. There will be a few spots, too, that won’t be tilled and seeds will be drilled straight into established pasture.
Additional thoughts and observations:
Grazing days – 4 days on 18 acres with 146 cows, 110 calves, and 6 bulls
Labor – setting up and taking down polybraid – two strips – 3 hours.
There is general concern that the annuals need to be stripped off for best utilisation because of the assumption that the cows will destroy too much of the forages. However, my experience is that there was very little waste overall and certainly not enough to justify 3 hours of labor in stripping off small sections. Having said that, i have to quantify that one strip allowed access to only 4 1/2 acres, then 5 acres, then about 8 1/2 acres. Perhaps larger sections would have shown more waste.
If conditions allowed less work setting up and taking down and one had more valuable annuals, then it may be better to take advantage of the benefits of strip grazing.
