LIVESTOCK NOTES
As I write this letter there have been 6
Show-Me-Select bred heifer sales in the state. By the time you get this, our sale in
Palmyra will be history also. The average of the 6 sales has ranged from $880 to $1085
with an approximate average of $1020 for all sales.
Just for fun I'm going to guess that the 350 head we plan to sell at Palmyra will average
$1029. Now you can make fun of me if I'm wrong!!
Are you interested in being enrolled in the Show-Me-Select program?? If so give me call,
because it is time to get started.
It is always a good idea to have some analysis run on the
hay and grain you are feeding. This may be especially true this year.
Lots of hay got wet and that always causes variation in nutrient levels. The extremely
high yields of corn may very well mean some unusually low, yes low, protein levels in
corn.
Talk to your feed dealer about running some feed analysis for you or give me a call. After
you get them, I can help with some ration adjustments if they are needed.
The "Red Books", pocketsize beef herd record books I get each year are here. They are free again this year. They contain a daily calendar and place for recording calving dates, breeding information, vaccinations, etc. Give my office a call if you generally get one or would like to try one.
Endophyte Friendly Fescue?Sounds too good to be true, doesn't it? Researchers have
been searching for ways to eliminate the animal problems and still maintain the
persistence of tall fescue for several years. One of the early approaches was to remove
the endophyte from the grass, but this reduced plant vigor and stand survival. More
recently, researchers are developing a technology referred to as friendly or novel
endophytes. These novel endophytes are inserted into endophyte free fescue and are
expected to improve animal performance and plant persistence. University of Georgia,
University of Kentucky, University of Arkansas, and Auburn University all have active
research programs in friendly endophyte technology. Pennington Seed Company named and
trade marked this new non-toxic seed technology Max Q. You may have read about Max Q as it
first appeared in the popular press in 1999.
Research results at this point look positive. Average daily gains on Max Q varieties have
been increased by 50% when compared to endophyte infected fescue. Body temperature and
blood prolactin levels were the same for Max Q and the endophyte free varieties. In
Georgia, fescue varieties were planted in small plots in bermudagrass sod and grazed
heavily during the hot and dry summers of 1998 and 1999. Endophyte free varieties lost 77%
more stand than infected toxic varieties. In comparison, Max Q infected Jesup lost 12%
more stand and Georgia 5 lost 35% more than the toxic varieties.
Since this is new technology, there are not any multiple year trials to measure
persistence in Northeast Missouri. I received a call from a Pennington Sales
Representative this fall. He was interested in establishing some on farm test plots in
Northeast Missouri. He did indicate that there would be limited cost to the producer. If
you would be interested in this, give me a call and I will help you get in touch with him.
You may have read in the popular press that there have been
some major changes in the State Performance Tested Bull Sale.
First, it will be held at the Callaway Livestock Auction Market in Kingdom City rather
than in Columbia. The date has been moved up to March 10. Finally they will be selling
unhaltered bulls if the breeder wishes to not break them to lead.
These changes will not affect our Northeast Missouri Sale. It will still be held the last
Saturday of March - March 31, 2001. We will be including carcass EPD information in
the catalog and have set some minimum EPD requirements for consigning to the sale.
AGRONOMY NOTES
2000 Crop Performance Books
The 2000 Missouri Corn and Sorghum Crop Performance variety trial results are now available at local University Outreach & Extension centers. Corn yields at the Novelty, Missouri location ranged from 229 to 173 bushels per acre. Sorghum yields in Shelby County ranged from 106.4 to 75.3 bushels per acre. These results are also available on the Missouri Agricultural Electronic Bulletin Board, Crop Performance Testing at http://www.agebb.missouri.edu/. If you would like a copy, please contact your local extension center. The 2000 Soybean Crop Performance results can be accessed via Agebb, although the results have not yet been printed. Soybean yields at Novelty ranged from 45.8 to 58.1 bushels per acre.
The Soybean Aphid
Late this summer, the Chinese
soybean aphid was first identified in northern Missouri. Previously, the aphid was only
known to live in Asia and Australia. While it is not known how the aphid arrived here, it
will most likely be a pest which must be dealt with.
As prior to this summer, the aphid had not been found in this country, little is known
about how the soybean aphid lives in the U.S. Most of the information currently available
is from China, Wisconsin, and Illinois. In China, of the 12-15 generations of aphid per
year, 3 to 4 are on soybean. It overwinters and reproduces on species of buckthorn. The
multicolored Asian ladybeetle proved to be an important predator of the soybean aphid in
Wisconsin, as in China.
In Wisconsin this year, late-planted (double-cropped) fields had the highest populations
of, and the greatest damage from soybean aphids. Varieties differed in terms of aphid
buildup and damage symptoms from the aphid.
The U.S. populations of soybean aphid rose rapidly, then disappeared almost as quickly.
Research suggests that under conditions of rain and high humidity, aphid populations
decline. This, combined with natural enemies, may be the reason researchers saw alarming
numbers of soybean aphid vanish in a matter of several days. In Michigan, natural
enemies were predators such as lady beetles, parasitoid wasps, and a pathogenic fungus;
all were spotted in heavily infested fields. Several insecticides were tested, and
provided mixed results. No treatment thresholds for the soybean aphid have been developed
as yet.
In several states, aphid development was favored in late-June through early-July by
temperatures of 71-77 EF and relative humidity less than 78%. After late-July, aphid
populations begin to decline as the nutritional value of soybean to the aphids declines.
Also at this time, the aphids began to move down into the crop, reducing insecticide
efficacy.
Damage from the soybean aphid is noted as rolled leaves, stunted plants with shortened
petioles and internodes, and early maturity. Defoliation from extensive aphid damage may
lead to early plant death. In addition to the direct feeding damage it causes, the soybean
aphid can transmit two viruses, soybean mosaic potyvirus and bean yellow mosaic virus.
Production losses from the aphid include fewer pods per plant, reduced seed weight,
reduced yield, and the virus transmission described above. The bean yellow mosaic virus is
not seedborne, and causes reduced oil content and increased protein content. The soybean
mosaic potyvirus, however, is seedborne, and infection can result in fewer, smaller,
lightweight seed, which may have mottled seed coats.
At this point, little is known about the biology of this aphid in the United States,
treatment thresholds, the efficacy and timing of insecticides, differences based upon
variety and date of planting, nor the role of natural control in controlling the aphid.
Careful scouting of fields will alert you to a problem, if one exists, and which point
treatment decisions can be made. Research projects are planned for next year which should
provide us with more information about this pest and its control.

As U.S. government support
to agriculture declines, understanding the economic impacts of agricultural trade and how
markets and competition are affected will take on added importance for farmers,
agribusinesses, policy makers, and agricultural lenders. With a 1996 Gross Domestic
Product (GDP) of $7.6 trillion and a per capita GDP of $28,700, the United States is the
worlds largest economy and a major market for both domestic and foreign producers of
goods and services. In 1996, U.S. exports totaled $582 billion (7.7% of GDP) while U.S.
imports totaled $790 billion (10.4% of GDP). International trade accounted for 18 percent
of U.S. GDP in 1996 compared to 12 percent in 1994. In fact the United States is now more
dependent on international trade than at any time since 1880-1914 when 16 percent of GDP
was generated by merchandise trade. Major export commodities include: capital goods,
automobiles, industrial supplies and raw materials, consumer goods, and agricultural
products.
While agriculture accounts for 2% of U.S. GDP and 2.8% of the labor force, it represents
10.4% of total exports ($60.4 billion), 4.3% of total imports ($33.6 billion), and
generated a $26.8 billion trade surplus in 1996..
Agricultural trade contributes employment, income, and economic activity to the U.S.
economy. Estimated trade-impact multipliers for 1996 indicate that to produce one million
dollars of agricultural exports required 15 workers. Each dollar of agricultural export
sales generated an additional $1.32 of economic activity. Agricultural exports required
the employment of 859,000 workers and generated $140 billion in business activity..
Imports also generate jobs and create economic activity. Leading imports include: crude
oil and refined petroleum products, machinery, automobiles, consumer goods, industrial raw
materials, and food and beverages..
Despite the contributions of international trade, some still believe that the U.S. should
not participate in an open international trading system. Call for increased protection and
isolationism are heard in some quarters. Reverting to a closed economy is not economically
rational in todays global marketplace. The notion of made in America has
become a myth, with assembled in America becoming a more appropriate term..
Trade policies are a mix of economics and politics, and much of the public information
about the potential impacts of these policies comes through news media, which tends to
focus on negative issues. The complexities surrounding the economic impacts of trade are
often improperly perceived, or viewed from a narrow perspective..
By its very name, international trade is perceived as something different than merely
doing business with firms in other countries. Discussions in the media about trade
policies, or attempts to settle trade disputes, cause international trade to be perceived
as us versus them, where one country gains only if another country loses. In fact,
international trade is not fundamentally different from the inter-regional trade among
states in the U.S. Perceptions about international trade persist, partly because the
losses from trade are concentrated and often highly publicized, while the gains from trade
are less visible and are spread broadly, going virtually unnoticed. Such perceptions also
persist because economist have not done a particularly good job of explaining why
international trade exists, and what benefits it conveys.
One way to understand why trade occurs and what benefits it brings, is that nations do not
engage in international trade, but rather the individual consumers and businesses within
nations do. When an individual in the U.S. buys a Japanese manufactured stereo component,
he or she has engaged in international trade. This participation occurs indirectly through
the power of consumer preferences and the competitive pressure faced by the retailers to
satisfy them. When a manufacturing firm buys some of its inputs from foreign sources, it
also engages in international trade.
Over two hundred years ago, Adam Smith in An Inquiry Into the Nature and Causes of the
Wealth of Nations, argued that competition in combination with individuals freely pursuing
their own self interest, or profit motive for businesses and the pursuit of satisfaction
by consumers, would result in the efficient use of economic resources, allowing society as
a whole to achieve its highest standard of living as if guided by an Invisible
Hand. Unfettered competition and individual choice are the core of American economic
philosophy and the primary forces that have enabled U.S. citizens to achieve a high
standard of living. Competition and individual choice are also why there is international
trade.
With rare exceptions, consumers are faced with incomes that constrain the amount of
material goods and services they can buy. To satisfy their individual needs, consumers
attempt to obtain the products they want most, at the best price. When purchasing a
television, attention is primarily given to product quality, reliability, and price, not
where the product was made. When purchasing clothing, characteristics, such as fit,
perhaps the designers or manufacturers name, and of course price, are much
more important than where the product was made. And if consumers want cantaloupe in
December, they are more interested in its taste and price than where it was grown.
Evidence supporting the minor role that country of origin plays in purchase decisions
abounds. While brand names and prices are prominently displayed in any retail store, one
is not likely to see information on country of origin prominently displayed. The reason
for this is simply that retailers provide consumers with the information they want in
making purchase decisions, and this information does not generally include country of
origin. Yet when decisions based on such information are made, and the goods or services
purchased are foreign-made, consumers have participated in international trade.
Even if consumer wished to buy American, it would be difficult to accomplish. The
following example of an automobile purchase illustrates this. Of the $10,000 paid to
GM, about $3,000 goes to South Korea for routine labor and assembly operations, $1850 to
Japan for advanced components, $700 to Germany for styling and design engineering, $400 to
Taiwan, Singapore and Japan for small components, $250 to Britain for advertising and
marketing, and about $50 to Ireland and Barbados for data processing. The restless
that $4000goes to strategists in Detroit, lawyers and bankers in New York, lobbyist
in Washington, insurance and health care workers all over the country and to General
Motors stockholders all over the world.
This example also explains why there is trade from the perspective of producers. Faced
with the realities of the market place, and the consumers demand for quality at the
lowest price, the competitive pressures of rival firms force businesses to pursue
cost-effective business strategies. While such strategies entail many facets of production
engineering and management organization, they also entail obtaining factors of production
and other business- and marketing-related services at the lowest possible cost. When
assembly by, or materials from, foreign firms or subsidiaries are cheaper, businesses have
no choice but to pursue these lower-cost opportunities. Competition from rival firms,
domestic and foreign, make such decisions necessary for businesses if they are to meet
market demands and survive.
In conclusion, the U.S. is fortunate in that its climate, natural resource endowments, and
technological knowledge potentially enable it to produce all of the products needed
without trade. However, without trade it is doubtful the U.S. would enjoy the standard of
living it does. From a regional perspective, maple trees could be grown to produce maple
syrup in Florida, and orange trees could be grown in Vermont to produce orange juice.
Floridians would pay a lot more for maple syrup and the citizens of Vermont for orange
juice. However, the fact is that Florida is better at producing orange juice and Vermont
is better at producing maple syrup, and by doing what each does best, the producer, the
consumer, and the economy benefits from more efficient utilization of resources and lower
prices.
International trade enables countries to specialize in what they do best and acquire the
things they have difficulty in producing. By so doing, resources are more efficiently used
on a global, as well as domestic basis, and these efficiencies are passed on in the form
of lower prices and economic growth.

With relatively high yields and low
prices, Missouri farmers are storing more grain this season. In some areas and on some
farms, storage space is limited. For this reason some farmers may build additional on-farm
grain bins. There are many different sizes and options available in grain drying and
storage systems. Each has its advantages, disadvantages, and associated costs.
Costs are a major consideration, and may be categorized as either fixed or variable. Fixed
costs occur regardless of the extent of utilization of a grain drying and storage system.
Examples are taxes, depreciation, interest on investment, etc. Variable costs on the other
hand are a function of level of use. Examples might include, labor, repairs, drying and
handling fuel, etc.
Fuel costs can account for a significant portion of the drying and storage costs for grain
and careful planning should go into a system to reduce this cost as much as possible.
Grain depth is an important factor in grain drying and therefore in the resulting fuel
costs. Extra depth increases airflow resistance, decreasing the drying rate. This extra
depth also increases fan power requirements and the cost per bushel of drying grain.
Reducing the depth in a low temperature drying bin can speed drying, decrease the risk of
grain spoilage and reduce drying cost. Typically, reducing the drying depth by one-fourth
will reduce the energy cost per bushel by one-third.
When buying "deep" versus "shallow" or "low-profile" bins,
it seems to make sense that the bin cost per bushel will be lower for a deeper bin. After
paying for the concrete floor and roof, the cost of an extra ring or two results in cheap
storage. However, this doesn't take into consideration the initial cost of a drying fan
and motor or the cost of operating the drying fan.
According to agricultural engineer, David Williams, in University of Missouri Guide G1300,
" 'Low-Profile' Bins for Grain Drying", a low-profile bin has a maximum grain
depth of 12 to 13 feet, rather than the more typical depth of 17 to 18 feet. In order to
hold the same amount of grain, the low-profile bin must have a larger diameter. Due to the
larger diameter, the low-profile bin will have a higher initial cost per bushel of
capacity due to the extra concrete, larger perforated floor, larger roof, etc. With the
low-profile bin, a smaller, less expensive, fan may be used. This may offset the extra
cost of the concrete and bin structure is some cases.
With fixed vs. variable costs in mind, Williams examined some of the costs associated with
low-profile bins relative to deeper bins commonly used for low-temperature drying. To
compare the two, low-temperature drying systems, complete with drying fans and motors,
were designed to dry shelled corn.
Fans were sized for bins from 27 to 36 feet in diameter to provide an airflow of 1.5 cubic
feet of air per bushel (cfm/bu.). This airflow is recommended for drying corn to
21-percent moisture or lower in the central half of Missouri on October 1 if filling in
one or two days.
Costs for bins, equipment, concrete and labor were provided by bin suppliers. Energy costs
were based on an electricity rate of 6 cents per kilowatt-hour. Bin costs included the
concrete slab, perforated floor, fans, motor, inside and outside ladders, power grain
spreader and 8-inch unloading augers. Costs do not include roof vents, heaters,
thermostats or humidistats. Medium-profile 8,000 and 10,000 bushel bins were also studied,
but the costs were similar to the deep bins.
With the values and assumptions used by Williams, the additional initial cost for a
low-profiled bin was $0.054 per bushel. However, the annual energy saved with the system
was $0.031 per bushel. This resulted in a payback period of less than 2 years. For the
10,000-bushel bins, the low-profile bin construction costs totaled $1.262 per bushel, 9.4
cents per bushel more than the deep bin. For the 8,000 bushel bins, the low-profile bin
totaled $1.323 per bushel, 5.4 cents per bushel more than the deep bin. The cost per
bushel between the deep and low-profile systems is small primarily due to fan costs. The
27-foot bin needs a 15-hp centrifugal fan at a cost of about $1,500, while the 33-foot bin
can provide the needed airflow with a 10-hp axial fan at an approximate cost of $1,000.
Likewise, for the 10,000 bushel bins, the 30-foot bin needs a 20-hp centrifugal fan at a
cost of more than $1,600, while the 36-foot bin uses a 10-hp axial fan at a cost of
approximately $1,000.
The electrical costs of the fans were calculated on the basis of fan operation for 30 days
per year at a cost of 6 cents per kilowatt-hour. At these rates, the low-profile,
8,500-bushel bin would pay the difference in initial cost after 1.7 years of operation,
and the low-profile, 10,000-bushel bin would pay back the difference in 3.2 years of
operation.
The time required for the low-profile bin to pay for itself depends on many factors
including bin capacity, electricity rates and airflow requirements. Some may not payback
as soon as the above examples. For smaller diameter bins in the 18- to 30-foot diameter
range, low-profile bins may actually have a lower initial cost than their deep
counterparts when fans and motors are considered. In the latter case, the payback is
immediate and the savings in energy costs from the very first day of operation is profit.
William's comparison was done in the 90's when both fixed and variable costs were lower
but with major increases in electricity and heating fuel prices in the past year, the
payback period is likely less than those he calculated. It should be noted that the costs
shown in his guide are not the total costs for drying a bushel of corn. It is assumed that
depreciation, interest, insurance, labor and repair/maintenance costs will be nearly equal
for systems of equal capacity.
For producers who already have the higher profile bins, Williams points out you can also
get some of the benefit discussed from an existing deep bin if you manage it as a
low-profile bin. Simply limit the grain depth in the bin to 12 or 13 feet. The benefits
will include a higher airflow rate, faster drying time and lower energy cost per bushel.
You will also decrease the risk of grain spoilage in the top layers of grain. Since you
will be using the same fan as before, no savings in initial fan costs will be realized.

For many cow-calf producers,
cutting costs has become a matter of survival. But when it comes to the bottom line, lower
costs will get you only halfway. You must also increase the performance of and add value
to your calf crop to stay competitive. Because 80 percent of herd improvement is directly
attributable to bull selection, determining what you can pay for a bull depends on more
than finding the lowest price.
Lets compare two Angus bulls, A and B. Their expected progeny differences (EPDs) and
the breed average for Angus sires are listed in table 1. If bull A or B sires forty calves
(twenty heifers and twenty bulls) from the same cow herd for four consecutive years, how
much more can you afford to pay for a bull with better genetics?
Table 1. Sire A and Bs EPDs Compared with Angus Breeds Average
Trait |
Birth Weight |
Weaning Weight |
Milk | Yearling Weight |
| Angus breeds average | +2.8 | +30 | +13 | +55 |
| Bull A | +2.0 | +44 | +20 | +82 |
| Bull B | +2.0 | +24 | +10 | +52 |
Growth Growth trait EPDs are expressed in pounds. If all the steer
and heifer calves are sold at weaning, what advantage does bull A have over bull B? Bull A
has a weaning EPD of +44 pounds; bull B, +24 pounds. You can expect bull A, on average, to
sire calves that weigh 20 pounds more at weaning. If 15 percent of the forty calves are
kept as replacement females, thirty-four calves multiplied by 20 additional pounds results
in 680 pounds of additional weight per year. If these pounds are valued at $90 per
hundredweight (cwt), yearly gross sales from calves increases $612 per year. Six hundred
and twelve dollars over four years results in $2,448 of increased gross sales from bull A
compared with bull B.
Maternal Dont overlook extra calf performance obtained by keeping daughters
out of bulls with superior genetics. Increased calf performance from maternal influence
can originate from increased milk production and growth potential of the cow. One way to
compare a sires ability to transmit milk and growth rate to his daughters is to
calculate maternal weaning weight, which is expressed in pounds and is equal to the
sires milk EPD plus one-half of his EPD for weaning. For example, bull As
maternal weaning weight would be one-half of +44 plus +20 or +42 pounds. Bull Bs
calculated maternal weaning weight would be one-half of +24 plus +10 or +22 pounds. You
can expect bull As daughters, on average, to raise calves that weigh 20 pounds more
at weaning than bull Bs daughters, assuming they are bred to the same bull.Consider
our example. If twenty-four females, 15 percent of the total calf crop each year, are
retained out of sire A and these cows stay in the herd for six years, there will be an
extra 2,880 pounds of weaned weight compared with that of bull Bs daughters. If this
weight is valued at $90 cwt, there will be an extra gross sales of $2,592 for sire
As daughters lifetime compared with that of sire Bs daughters
lifetime. Increasing weaning weight through increased milk production often increases feed
costs to meet additional milk production. Since optimum milk production is different
because of differences in environment and nutrition, we recommend that each producer
analyze his own requirements and make breeding decisions accordingly. Selection should
concentrate on a moderate milk production EPD with an increased weaning weight EPD.
Lets get back to our question. You decide to purchase a bull this spring and
identify a particular sale that offers you the most selection. You look at the bulls and
narrow the choices to sire A or B. Both are visually appealing and have good pedigrees.
You compare each bulls EPDs and find that sire A outperforms sire B on paper. How
much more can you afford to pay to purchase sire A?
Compared with sire B, sire A should improve this herds production potential by
approximately $5,000 over his lifetime. This example does not necessarily suggest you
should pay an extra $5,000 for bull A, but it helps explain why a sires genetic
potential is such an intricate factor in bull selection. Purchasing a bull is a long-term
investment that influences your herds productivity. Consider all the factors when
you decide to purchase a bull.
