The brown marmorated stink bug (BMSB) is causing frustration for home owners and farmers across America. These shielded, flying, stout, and brown insects are thought to have invaded the US from Asia in the mid-90s. Since the first one was positively identified in 2001 by Penn State they have spread across the country and now pose threats worth $21 billion to specialty food crops annually. They cause damage to many food crops including fruits, vegetables, and grains.

There are many different kinds of less common stink bugs in our region that including beneficial, predatory stink bugs. This past week I identified a type of stink bug I hadn’t seen before that was collected from a Noble County home after the holidays. It was distinctly different from the BMSB and turned out to be the twice-stabbed stink bug. Stink bugs do not create structural damage to homes, nor are they a problem if consumed by pets, and they do not bite. However, they are a severe annoyance and threat to American commodities. Damage from the BMSB sends a significant amount of valuable fresh fruits and vegetables to be processed and canned, instead of marketed whole and fresh each year. It is the BMSB that is most likely causing you distress at home this winter.

They enter your home in search of a place to overwinter until Spring. Their large size and ability to fly long distances makes it difficult to ignore their presence. They persistently enter homes through any crack or crevice they can fit through. Pesticides are unnecessary and generally ineffective tools for home control. The best way to keep stink bugs out, is to eliminate their way in by sealing cracks, door frames, windows, and utility access areas in your home. If you have them in your home, don’t be ashamed. Everyone does. Don’t let them get cozy. Find them. Sweep them up with a vacuum. Catch them in a pheromone trap. Drop them in soapy water. Freeze them. Smash them. Compost them. Whatever you prefer, stop them in their tracks. What serves as your annoyance this winter will become a severe agricultural pest this spring.

It’s January in Ohio. Most graziers are probably feeding a good portion of hay as a part of their animals’ daily ration. Even if there is a supply of stockpiled forage available, we tend to make hay available just in case they need a little extra. It is likely that grain is also part of that daily ration. Well, how do you know how much hay, grain, and pasture they need? No one wants to leave their animals hungry. In addition, we don’t want to waste time or money with unnecessary feeding. Figuring out the balance can seem like a guessing game, but a great place to start is with a hay test.

Testing the hay you are feeding is well worth the price of sample analysis. Collecting a sample is not complicated and typically results are available from the lab within two weeks. You can acquire the tools and kits on your own to submit samples, or you can find them at most county Extension offices and often from Soil and Water Conservation Districts. Ag co-ops usually offer sample analysis services as well. Whoever you chose to go through, be sure to select the analysis package that will give you the detailed results you desire. The package that costs the least will probably still leave you guessing. My typical suggestion is to select a test that will give you values for moisture, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN), and Relative Feed Value (RFV). Once you receive the results of your analysis, the challenge of interpreting the values arises. How do you know what values are good or bad?

Your hay test results will list values on a dry matter (DM) and an as-fed basis. Nutrients will appear to be higher for DM basis, because all the remaining water (% moisture) in the hay has been factored out. For CP, values of 8% or greater are desired. For ADF, lower is better. Increased ADF values equal decreased digestibility. Neutral detergent fiber is the amount of total fiber in the sample, which is typically above 60% for grasses and above 45% for legumes. As NDF increases, animal intake generally decreases. For TDN and RFV, the greater the values, the more desirable the forage. These values are useful for comparing your forage to other feeds available on the market. Once you have these values compiled you can start formulating rations based on nutritional values of the hay.

First, consider the needs of your animal. Stage of life, current weight, desired weight, and environmental conditions are all important factors. For the sake of an example, let’s assume we are developing a ration for a growing Angus heifer. Currently, she weighs about 800 lbs. and we want her to gain about 200 lbs. by the end of March. Ideally, we would like her to gain about 2 lbs./day. Now, let’s take a look at a hay test example and assume it is for our hay (see Figure 1.1).

Figure 1.1:

According to the information from our hay sample and the recommendations from the National Research Council for beef cows, we could expect this animal to eat about 21 lbs. of hay daily and gain 1.75 lb./day, coming in just short of our goal. This hay should be adequate for meeting the heifer’s energy needs as her main feedstuff. If we think it is worth the investment, supplementing with some high energy, high protein grain could help reach our desired average daily gain (ADG).

Soybean meal has an average of about 44% CP. Supplementing 1-2 lbs. of soybean meal (a pelleted form will increase animal intake) should provide the additional nutrition to reach our goal. Whole shell corn is about 9% CP, which is lower than the CP content of our hay. Unless we are concerned about our hay supply, supplementing corn may not be significantly beneficial.

This was just one example of how a hay test can help with the development of livestock rations. Recommendations will vary depending on types of hay, time of year, animal species, stage of life, and production goals. With so much possible variation, every little bit of knowledge we can secure is helpful for developing production goals and expectations.

Hay tests may not reveal ideal results and they can vary drastically between cuttings. That is the reality of attempting to manage nature. We can rarely do anything under ideal circumstances, but we do the best we can. As you look ahead to the next growing season and putting up hay once again, do everything you can to efficiently improve forage quality and nutritive value of your stored resources. The better the nutritive value of your forage, the less you will need to supplement and the more money you can keep in your pocket. Testing and formulating rations takes some effort, but once it becomes routine it will come with greater ease.

With that, I will leave you with a quote from Jim Rohn, “Success is neither magical nor mysterious. Success is the natural consequence of consistently applying the basic fundamentals.”
