Dr. Housewright's talk is titled
"Where have all the cowboys gone?
Challenges in Animal Agriculture for a New Century"
Abstract:
A fitting question, considering the urbanization of our culture and the
loss of attachment to agriculture. Instead of hearing in conversation, "I
have some cows!" or "My Dad used to have some old cows," now we overhear
"...seems like my grandfather used to have a farm of some kind."
This has not
only impacted the culture and knowledge outside, but also inside
agriculture, especially animal agriculture. Animal agriculture is on the
threshold of some exciting innovations and applications.
One of the latest developments is "EID" or electronic identification of
cattle. This technology will ultimately allow for tracing of cattle from
the initial producer through the industry and directly to the consumer. The
most widely used argument against the use of this technology is cost. If
they take the time to buy the tags, put them in the cattle and keep the
records, will they be compensated for this additional expense? More
questions than answers exist with this new program, but due to pressure the
beef industry will eventually be forced to adopt this technology.
Finally, "Where have all the cowboys gone?" will
have a direct impact on the direction of future research generated by the
Department of Agricultural Sciences. A new segment in the beef industry has
emerged over the last few years and has become a dominant fixture on the
landscape in East Texas. The backgrounding or preconditioning producer is a
growing segment of the industry that takes weaned calves and prepares these
calves for the feedyards. With the loss of practical "cowboys" who can spot
sick cattle and treat fresh calves the industry is becoming increasingly
dependent on making sure calves are healthy when they arrive at the
feedyards. This has opened the floodgates for new research in the area of
nutrition and manipulating immune response. Feed consumed by stressed calves
is lower than unstressed calves and this low intake coupled with low
nutrient intake could compromise immune function (Cole, 1996) and
potentially increased susceptibility to infection. Cole (1993) noted that
the trace mineral requirements for newly weaned stressed calves does not
seem to be greater than unstressed calves, however, due to their lowered
intake, additional supplementation may be warranted. Several trace minerals
have been identified as potential stimulators of immune response, most
notably Zn, Cu, Cr and Se. It was determined by Corah et al. (1996) that a
great number of cattle coming off grazing are in fact Zn deficient. In a
survey of 18 states it was found by Corah et al. (1996) that only 2.5% of
cattle received adequate Zn. It has been a recent development to increase
the bioavailability of these trace minerals in an attempt to enhance immune
response in fresh cattle. These areas will become the focal point of
continued research in the Department of Agriculture.
