Hay Quality and the Power of Brand Awareness

27 Mar

Recently I had two conversations about three weeks apart, with two distinct individuals who wouldn’t know each other if they were sitting together on a plane, but the conversations were eerily similar. The conversations revolved around hay quality. Quality hay is often thought of as an oxymoron, similar to” efficient bureaucracy”, and it dawned on me that we as Extension personnel still have a long hard road ahead of us in terms of teaching about quality. Human beings compartmentalize, we put things in nice categories, “the good side of town,” the “kid-friendly restaurant,” those “mean people,” and so on. We do the same with hay and our forages. Ryegrass hay is GOING to be good hay simply because its ryegrass, right? When I think of ryegrass I think of 2.5-3 lb average daily gain in growing cattle, (nothing to scoff at), others think of lush green fields, early spring, cattle fat, happy with their backsides covered in green. Most of the variety tests (I am not speaking to any specific variety here) and our ryegrass pasture samples show a forage product that is high in total digestible nutrients (TDN, mid 60%) and high in crude protein (CP,18-24%); in short, a very good feed for ruminants. I suspect most of us have all those thoughts in our heads when we hear about ryegrass hay. Being stewards of the land, and understanding the limitations of production agriculture (timing, weather, equipment), we KNOW that we are not going to have hay that is as high in quality as the forage in pasture, but how bad can it be? I was fortunate enough to work with Dr. Lemus on a small project looking at hay quality among samples sent in from MS to the LSU Ag Center Forage Lab. We found that on average ryegrass hay samples were 10% CP and 56% TDN, which is a far cry from what we have sampled in pasture!  When confronted with a cattle nutrient requirement question, my Standard Extension Questionnaire that I start with is “What are they eating?” “Ryegrass hay” is the response. “Did you test it”, I ask. “No” is the reply, “however, its ryegrass so it has to be good, besides I tested some a few years back and it was really good.” I think most of us rank hay/forages in our minds, saying to ourselves that ryegrass better than bermudagrass, which is better than bahiagrass, which is better than ____(Fill in the blank)_____. This is what the marketing people would term “brand awareness.” The “Ryegrass” brand is equated with quality; hence ryegrass hay is quality hay. In a practical setting all forage varieties have their strengths, and fit into individual production scenarios and locations. Data from the White Sand Branch Station have demonstrated similar performance with cattle grazing bahiagrass or common bermudagrass pastures, as well as both pastures being similar in forage quality. Bahiagrass is often associated to be of lower value, but ask any producer and they will tell you about the mismanagement and poor fertility bahiagrass can tolerate; is that not a strength in itself?

In my opinion, I feel the Extension specialists have done an excellent job in showcasing and helping producers understand the various varieties out there, and they should be commended. However, I think that too many of us automatically assume that forage type equals quality. In the scenarios I discussed at the opening, cattle were in a nutrient deficient state, and the producers were at a loss because they thought they had “good” hay, simply because it was ryegrass! When we think of hay production, we know there are many factors that influence quality: 1) Forage variety, 2) stage of maturity, 3) nutrient management, 4) environmental conditions and 5) storage conditions. Is it fair to accurately judge the quality of hay based solely upon one of the four factors? One might even argue that stage of maturity would have a greater impact on quality than variety. All too often yield trumps quality, simply because it makes us feel better to say “I put up # tons of hay off of 10 acres last week”.  Talking with our friends, we NEVER want to be the one who caught the smallest fish! As our input prices increase, we must strive to become more sustainable (after writing grants, it pains me to use that word!), and ensure that every dollar we spend results in increased production. Rather than worry about the size of fish we caught, and rather than assume what we have is quality because of its name, we must begin to judge hay more critically, and in looking at the factors that affect hay quality, we can assume that certain varieties have the POTENTIAL to be higher in quality, but that alone does not make them higher quality. Additionally, if we are needing our hay to be high quality, we must test, test, and test it to ensure that it meets our standards, rather than assume it does simply due to the variety it is. The danger exists when everyone involved in the decision making and problem solving (producer, vet, Extension person, etc.) assumes that because a hay was a certain variety it was high quality, and the real problem is never addressed. In both cases, producers were dumbfounded that they hay (or lack of quality hay) was the big part of their issues. In another instance, a producer was astonished that his ryegrass hay was lower quality than his bahiagrass; he could not wrap his mind around that fact (a testament to the power of brand awareness).

In summary, the surest and best way to truly know the hay quality is to simply test it. Hay sampling equipment is available in most county Extension offices, and most Extension personnel will be happy to sample it with you or show you how to sample your hay. I would also challenge everyone (myself included) to begin thinking of hay in a different manner, and rather than compartmentalize hay into these pre-conceived categories based upon forage type, we compartmentalize hay into quality ranges based upon hay test results.

Research updates

31 May

It has been a while since I have posted last, and had I not met with some friends today it probably would have been a while longer!  Anyway, I was telling my friend about what all we’ve had going on at the station, and he replied “no need to do that I read your blog/newsletter, I’m up to date”.  This guy is famous for his sarcasm, so I took that as a kind request to Post Something! I think I lack a “creative” gene in my DNA, and I find coming up with topics very difficult at times, so I take the easy way out and find other things to do.   I have started to do a better job updating our Facebook page (White Sand Branch Beef Unit; shameless plug), and I promise, my loyal readers to do a better job with this.

We have had a busy winter/spring.   We had an implant study going on with ryegrass cattle, did an encapsulated fertilizer study, then we were fortunate enough to work on a contract project with a private company, which allowed us to almost triple our research capacity at the Experiment Station.  We now have 38 replicated  pastures (which the crew essentially built from the ground up -water troughs, gates, etc., in a span of 5 wks) , which for the types of studies we do, means we have 38 experimental units, which allows us to increase the number of studies, and can increase the turnaround on projects as well.  For example, a “rough” number of replicates needed to find a difference is around 4 or 5.  If we have four  treatments, then we need anywhere from  16-20 units (four x 4 or 5 = 16 or 20).  Studies can eat up space really quick!  I hope to discuss this further in greater detail in a later blog, so stay tuned…

Before I get out of topic, let me share what we’ve been doing the last few months at the experiment station:

Long term implant study.  We looked at a 200 d versus a 70 day implant (given twice) on performance of beef cattle grazing ryegrass pastures.  As expected we had an implant effect compared to controls, the cattle were shipped to Iowa where our friends at Iowa State will be getting them fed out.  This is the second and final year of this study.  Last year’s data will be presented at the ASAS national meeting in Indianapolis this summer. There was an implant effect during grazing, but at the feedlot, there were no carry over effects noted.  Many times our producers are under the assumption that by implanting cattle while they graze they somehow hurt carcass quality.  We did see a slight dip in % Choice, but the carcasses were much heavier thereby more than making up for that loss.  That was something I learned at Texas Tech, while working there, with the cattle we shipped to slaughter and reviewing the close outs.  A heavier carcass  has greater benefit despite the loss from losing a bit of quality grade.  Anyway it will be interesting to see if the cattle do similarly this year…

encapsulated urea.  We have done some work looking at an encapsulated urea product compared to other commercial fertilizers on ryegrass production.  This product has a coating around it that releases ammonia when soil temperature and moisture levels are correct.  We have not completed the total analyses yet, but as of the March harvest, the encapsulated product alone or mixed with urea (50:50) had better response on the small plots compared to conventional fertilizer types.  We have begun a hay study looking at the product’s effects on hay production.

Hay injection systems.  We tested a commercially available product that is designed to be injected into round bales to increase quality.  Injection (at label directions) did not improve quality. Injected bales were put into pastures randomly with non injected bales to see if there was animal selection preference, and none was noted as well.  We hope to do some follow up work looking at increasing the level of product applied.

So in a nutshell those were the three major studies that we worked on this spring.  We have sorghum sudangrass in the ground and are making preparations for our final year of our N-source study.

Remember to “Like us” on Facebook and keep up to date with what we have going on.  2013-02-22 07.59.41sampling 2013-05-07 09.19.29

South MS Branch Christmas Letter

15 Dec

I happen to receive a couple of Christmas letters each year from friends/family all over the US, and it is interesting to hear the goings on of what everone has been up to.  I decided to take a new twist on this and do a South MS Branch Christmas letter to let everyone know what we’ve done this past year.

At the writing of this letter, we have four completed projects for the year, and are in the middle of three, and hope to begin one more before year end.  Words cannot express the gratitude I have for the White Sand crew -  Larry Fitzgerald, Melvin Gipson, and Roy Gipson.  We had one other person, Kevin Odom, but he retired in May.  We have truly asked the guys to do more with less, and they have stepped up remarkably.  Anyway in a rough chronological order here go the projects:

Implants for cattle on ryegrass:    we examined the use of a long acting (200 d) implant for beef cattle grazing ryegrass.  One concern we hear regarding the use of these implants are the potential negative effects seen at the feedlot.  Sometimes this is said by others to be able to purchase cattle a bit cheaper (lighter-weight) or take advantage of the “pop” at the feedlot level when they are finally implanted.  We saw that the cattle implanted had better performance on ryegrass and no differences at the feedlot (all cattle were implanted and treated the same at the yard).  There was a slight decrease in marbling but the added performance made up for that.  We will be receiving cattle for the 2nd year of the project in couple of weeks.

Implant managment for calves:  A graduate student I am working with Brad Jones (also of Stone County Extension Fame) has been working on this project.  We have not completed the analysis of this years study, and the calves on this project have found a new home in sunny Iowa enjoying life at Gregory Feeders.  We hope to get feedlot and carcass data back when the cattle slaughter in the spring (so we can examine any carryover effects).  In a nutshell, we were looking the timing of implanting the cattle (at calfhood still with mama, or at weaning) and determine which option might be best for producers.  Additionally, we have noted somethings regarding performance of newly weaned calves that we were not expecting.

Biological soil additive for sudangrass:  Many of you are familiar with these types of products that are supposed to be added to the soil and increase nutrient uptake by the plant, thereby improving the forage mass and quality.  We did a study with a product, looking at use of the product at three levels of N fertilzation (0, 30 and 60 lbs of N per acre).  Due to inconsistent weather we had poor N uptake, so no N differences were noted.  We did not see any effect of the soil additive either.

N-source.  This one looks at whether it is more benefical to supplement cattle N source, or apply it as a fertilizer in terms of performance and N cycling by the animals.  This was the 2nd year of the project (scheduled for 3).  The cattle that were supplemented had greater performance compared to their counterparts.  Fecal N was similar between cattle grazing fertilized pastures and cattle supplemented.  We are in the process of anlayzing this years samples for quality.

Liquid feed for cows.  We are currently looking at liquid feed for cows.  One of the biggest concerns many have for liquid feed in truely having a handle on intake.  We are doing a small project examining intake of liquid feed to have an answer to that question.  In one group measured in early Dec., the cattle (22 head) consumed 75 gallons over a 42 d period.  That equates to 0.08 gallons per head.  With the weight of the product at 10 lbs per gallon we are looking at right under  a pound per head (0.81 lb) at a cost of about $0.21/day/head.  We will have the complete data done by the end of the winter.

Silvopasture.  Stephen Dicke, at Central R&E obtained a grant to look at the establishment of long-leaf pine and silvopasture.  The McNeil Unit was the ideal place for this.  So in  Oct, the White Sand crew and Stephen began prepping the area for tree planting.  After much work the site is ready and we hope to have this set up and going by the spring.  This will provide us with a unique opportunity to look at forages from a unique standpoint.  Stay tuned.

Encapsulated fertilizer product.  We are currently conducting a project looking at using an encapsulated fertilizer product that is designed to release N at more optimal growing periods (based upon soil and envirnomental temperature).  The first application occured on Nov. 14.  We will keep you up to date.

Hay injection.  Rocky Lemus will be helping us with this project.  We will be looking at effects of two hay injection liquids on feed intake and hay quality.  We hope to start this later in the month.

Thanks about it from this side, we want to thank all of you who have helped us and supported us throughout the year.  Also, if any of you have an idea or issue that you think we need to look at, please don’t hesitate to tell us.

Winter supplementation for beef cattle

27 Nov

Supplement:  Something added to complete a thing, make up for a deficiency, or extend or strengthen the whole

Among some beef producers the word has a negative meaning.  However, if taken for what it really should be it can be an effective tool to help increase stocking rate, forage utilization and at the end of the day productivity.  If you look at it from a human perspective, many of us take our vitamin supplements, because we feel that through our lifestyle, diet, age or a combination of any of the above we need to supplement what we are not getting.  The same is true for beef cattle.  In the context of this discussion, I will focus on feed supplements since we all know we should already be supplying a good quality mineral to the herd.

Feed supplements should be used to make up for any deficiencies that are not being met by the basal diet alone.  Supplement does not mean ad lib feed for the herd, supplement should be making up what is lacking in the diet.  When commodities were cheap, many producers probably overfed, however, with rising inputs we have to be a bit more efficient in our management.  When a producer calls wanting to know what supplement to use or get, often the answer is a series of questions, and we don’t ask those questions to be nosy, rather we want to know what our target is and what we need to do to achieve the final goal.

Know your goals:   A high lactating beef cow 60 days post-partum will have much different requirements than a dry cow, which will be much different than a stocker that needs to gain 2.5 lbs/daily.  Is the operation trying to increase the stocking rate?  These questions need to be addressed in order to determine the need to supplement and to determine how much.  Data from Texas show that with most supplements will reduce forage intake by 0.6 lbs of forage for 1 lb of feed.  By supplementing the group you can effectively increase stocking rate.

Know your base feed:  Whether it is stockpiled grass or hay, know what it is and know the quality.  Random pasture and hay samples can be used to help you determine what your base line is.  Dr. Lemus, MSU Extension Forage Specialist has a great article on this topic here http://msucares.com/pubs/publications/p2539.pdf.  Remember what the word supplement is, we need to make up what is lacking.  By having an understanding of what is lacking it is much easier to calculate what we need to feed, and it would be more efficient.  A hay or forage that is 10% CP 55% TDN requires less supplement to meet requirements than hay that is7% CP and 47% TDN.  Remember nutrients will cycle back into the soil via feces and urine, so rather than overfeed, we need to supplement and hit that target.  Additionally, by testing the base feed, we can also determine what nutrient will be the most limiting.  If protein is the nutrient of need, do we need to buy soybean hulls?  Probably not.  Conversely, if TDN is the nutrient in need, do we need cottonseed meal as much?

When choosing a supplement there are many factors that need to be considered.  Factors such as availability of the feed, commodity storage capabilities on the farm, handling characteristics of the feed, and convenience all play a role in a decision.  With many operations limited by time and help (since many producers do have real jobs that supplement their cattle job), convenience and handling are big items.  Additionally, farm demographics tell us that the average cattle producer is not large (30 head or so), therefore, we can hypothesize that they probably don’t have the storage capabilities to handle bulk loads.  One option is the availability of winter annuals, especially in South MS.  Winter ryegrass is an excellent feed source and can effectively be used for supplementation through controlled grazing.  In some cases producers have even shifted their calving dates to take advantage of this forage for their beef herd.

In closing remember supplementation is a tool to increase productivity and efficiency.  It should work in conjunction with existing forage and should work to strengthen the whole.

Sugar Cane Feed

19 Sep

Hello Everyone,

I have joined the world of the on-line bloggers, although to many, my blogs won’t be that interesting, unless you like cattle and what they eat!

One of the first things I wanted to do was share this information with everyone.  It seems that a company has recently began to market a feed composed of sugar cane bagasse and some distillers grains.  The bagasse is the fibrous residue that is remaining following the syrup manufacutre.  We first became aware of this a little over a week ago, and have been keeping our eye on it.  Right now this product is available for sale @ $120/ton fob New Orleans.  We have analyzed a sample of this product and the analysis is listed below.  We (myself and Rhonda Vann at Brown Loam) are currently making plans to do a small type of study with this product to get a better handle on what we might exptect this feed to do.

Here are a couple of things you and your producers should be aware of:

Right now they only handle semi-loads, the option for supersacks may not be there, and they are in the process of “developing” the feed more, so the formulation may change

Sulfur is rather high (due to the DDGS in it, and the bagasse itself).  From a NRC perspective this feed fed alone with nothing else is at a level to be considered toxic.  Therefore you might want to ensure that this is fed in conjunction with something eles (pasture or other hay)

Phosphorus is high as well, and the Ca:P ratio is non-existant almost, therefore a good beef mineral with high level of Ca should be fed if you are going to use this product.

Here is the analysis, all values except dry matter are on a dry matter basis

  • Dry Matter                      67.87%
  • Crude Protein                 23.7%
  • ADF                                  55.6%
  • TDN                                  48.5%
  • Sulfur                                 0.56%
  • Calcium                             0.09%
  • Phosphorus                      0.73%

My final thoughts are that while this product might make a good protein source, I would be wary of using it as the SOLE source of feed in your operation.  If you are using it to extend pasture or  hay (much like you would a supplement), it may work for that, just be aware that right now as its blended it is low in energy.  Also if you are mixing feed, this product may work great for added protein and some roughage.  Just be aware of the mineral issue.

Should any of you have any questions I will be happy to answer them.  601-403-8777 office, email drivera@ext.msstate.edu
