The Cows’ COVID Diet

We’ve been feeding the milk cows a TMR for many years.  Until last fall, it was fairly complex, including a specially formulated multi-ingredient commercial blend.  Last summer we made a decision to simplify the ration to include only corn and corn silage we raise, alfalfa hay we were purchasing from a neighbor, dried distillers grains (DDGs) and soybean meal.  Now market conditions have led us to add a little complexity. 

Fall Fieldwork

The guys finished the first round of silage chopping back at the beginning of August. We mentioned several times that we had some corn come up late, and they just finished chopping that corn this week. Our first corn had a decent amount of grain for its size and actually yielded a better quality silage than last year’s crop; there was just quite a bit less of it because the plants were so short. It has been tested and is being fed to the milk cows without incident from nitrates or aflatoxin.

The late corn may be a different story. There was very little grain on even shorter plants. The grain that was there was drier and the plants were greener than corn we traditionally chop. We will need to test the silage for both nitrates and aflatoxin. If it contains aflatoxin, we may still be able to feed it to heifers that won’t be milking. If it contains nitrates, it would be harmful to any animal, but it’s our understanding that the chemical process that occurs in the silo would solve the nitrate issue.

We chopped 100% of our corn, so we haven’t had to get the combine out yet. Our soybeans are only about knee-hight, but they put some pods on. They won’t be ready to harvest for a few weeks and have just started to “turn” in the last week or so. As the plants dry down, they change color from green to gold.

Soybean foliage turns from green to gold as the plants dry out before harvest.

Besides fall harvest, the guys have been planting fall crops. We planted three different forages on one farm.  First, we borrowed a no-till drill from a neighbor to plant oats that we hope to chop for silage this fall. They’re up and growing – probably about 4” tall. We hope they grow quite a bit more before we get a hard frost. We also used the no-till drill to plant rye that we will chop next spring. The rye is growing well (about 6” tall now), and we may also be able to mow it this fall if it gets tall enough. We then worked the ground on part of the farm and seeded alfalfa. We will mow and bale the alfalfa 3 or 4 times each year for the next three years.

We also ordered seed for both triticale and turnips which we will plant on one of the other farms that we just finished chopping. Rather than harvesting these forages, we plan to graze heifers on that farm.

We’re trying to raise enough feed for our cows and calves for the next year, so we have to be somewhat creative with our crop rotations and are trying some of these forage crops for the first time (triticale and turnips). Hopefully we’ll continue to get some moisture and the frost will hold off long enough to produce some feed to supplement what we’ve already harvested.  In the meantime, we’ll be busy in the field

Drought 2012

Everyone knows we’re in a drought. It seems like it’s all you hear about, especially if you know any farmers. Everyone also knows that a drought means its dry.  Maybe you’ve heard that we’re 10″ behind average precipitation, but maybe you don’t know why it matters for us and our dairy.

Pastures

Last Sunday we moved some heifers home from a nearby pasture that we rent. The pasture has two water sources – a creek and a pond. The creek has been dry for months (usually is in the summer), and the pond had been dwindling. That Sunday, it was gone. It was 105 degrees, and the calves had no water. There wasn’t much green left for them to eat anyway, so now they’re at the dairy where the cows and calves have access to the same water we drink.

A couple of weeks ago we repaired fence around the “Junkyard Pasture” because “Below Bud’s”, which I would call our primary pasture, was pretty bare. Thankfully the two pastures connect because the Junkyard Pasture also currently has no water, but Below Bud’s has a frost free water. The dry cows and bred heifers can graze the Junkyard Pasture and can come up to Below Bud’s for water. It’s not ideal, but it’s working okay, and so far the fence has effectively kept them in the pasture rather than the corn field.

Crops

I rambled on about our corn silage situation last week. We feel fortunate that most of our corn did put some grain on and overall has been better than we expected. Some of the corn (planted the middle of May) laid in the ground a full month until we got a rain and came up around June 15th. That corn is very short and just tasseled this week, so it’s fate is yet-to-be-determined.

David finished chopping corn silage (until the yet-to-be-determined corn is ready) Monday, and the bigger of our two pit silos was full.  It took about 40% more acreage to fill the silo than in an average year due to reduced plant size and yields.   

I discussed our soybeans’ need for rain in June. Thanks to a timely rain, they came up. However, we haven’t had much moisture since, so they fall under the “yet to be determined” category also. They’re not very tall, but are alive and starting to bloom. 

We also raised brome hay that we mowed and baled earlier this summer.  Many of our neighbors reported about half as many bales per acre compared with a typical year.  Our yield was closer to 75% of average, but it was definitely a noticeable difference.

Feed

In addtition to not being able to raise as much feed, prices for the feed we will need to buy are much higher than usual due to the drought. Both corn and soybean prices are approximately 33% higher than last year’s prices, which we considered high at the time.  We will likely need to buy some corn because we chopped all that we grew, and our commodity blend typically contains soybean meal.  Hay is hard to even find for sale locally, and we’ve been hearing of prices more than double those of an average year.

The drought also affects the quality of feed.  There have been many reports of corn crops containing aflatoxin, which could be passed to the milk if we fed corn containing it to the cows. There’s also a risk of our corn silage containing nitrates, which can be deadly to cows. Under drought conditions corn stalks can contain nitrates. If you shell the corn, it doesn’t matter, but when you chop it, it could. We will test our silage before we feed it for this reason. 

Cattle

All of these things indirectly affect our cattle, but the cows are directly affected by the drought’s partner in crime – extreme heat. Our facilities aren’t great for keeping cows cool (yet), and the cows don’t like the heat at all. It affects their appetite, production, and reproduction. Yes, it’s summer in KS, and we do expect it to get hot. However, we had a record number of days over 100 degrees in the month of July, and we started having 100 degree days in June.

As we head into August, we don’t expect the heat to subside.  It would help if it were less consistent, though.  More than the high high temperatures, the high low temperatures have hurt the cattle.  When it doesn’t get below 80 degrees at night, they have more trouble cooling off from the day’s heat.  Monday morning it was in the sixties, and I imagine the cows enjoyed it as much as I did.

So Now What?

The drought has been a major challenge, and it’s not over.  This something we never could have expected to face in our first year operating the dairy, but it’s also not a new problem.  This New York Times graphic shows how drought is and has historically affected our country.  Like many generations of farmers before us, we will do the best we can with the hand we’re dealt.  Over the next several months, we will manage our resources carefully and hope for much needed improvements in economic and environmental conditions.
