Wildlife Care Clinic Serves To Educate, Rehabilitate, Travis Saveraid Jan 1997

Wildlife Care Clinic Serves To Educate, Rehabilitate, Travis Saveraid

Iowa State University Veterinarian

''Will someone from the Wildlife Care Clinic please come to the front desk?" The message, barely audible through the pager static, sends Tim Hanks running to the Small Animal Clinic receiving desk. A worker from the Story County Conservation Board stands patiently with a large perforated cardboard box at his feet. "A woman found this redtailed hawk under a powerline. It must have flown into the wires and broken its wing." Hanks takes the hawk and enters it as a new patient under the care of the Wildlife Care Clinic (WCC) at the Iowa State University School of Veterinary Medicine.

First Records For The Blackmask Racer (Coluber Constrictor Latrunculus) In Eastern Arkansas, Stanley E. Trauth Jan 1997

First Records For The Blackmask Racer (Coluber Constrictor Latrunculus) In Eastern Arkansas, Stanley E. Trauth

Journal of the Arkansas Academy of Science

The presence of the blackmask racer (Coluber constrictor latrunculus) in eastern Arkansas was first demonstrated by examination of a series of color slides of live specimens now preserved and deposited in the Arkansas State University Museum of herpetology. Adult color pattern is of paramount importance in the definition of subspecies of C. constrictor, and this is especially true for C. c. latrunculus. This subspecies is characterized by a conspicuous black stripe that extends from the postnasal, through the eye and onto the temporals or anterior dorsal scales. The dorsum is slate gray, and the venter is a pale grayish blue ...

Determinants Of Prices For Purebred Beef Bulls, D.D. Simms, R.P. Jr. Bolze, J. Geske, Kevin C. Dhuyvetter, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Animal characteristics and sale price data for 1651 bulls sold at 26 Kansas purebred beef sales during 1993 were collected and analyzed to determine which factors affected price differentials for beef bulls. Bull sale price varied, from $650 to $20,000 per head. Regression analysis was used to determine the price differential associated with bull traits and marketing factors. Black bulls in the Simmental, Gelbvieh, and Limousin breeds brought premium s of 15% to 53% compared to their nonblack peers. Conformation, disposition , and muscling affected sell prices. Bulls with lower birth weights and birth weight expected progeny differences (EPD) brought ...


Protein Requirements Of Growing Steers Limit-Fed Corn-Based Diets, R.H. Wessels, Evan C. Titgemeyer Jan 1997

Protein Requirements Of Growing Steers Limit-Fed Corn-Based Diets, R.H. Wessels, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Seven steers (513 lb) were used in an experiment to investigate optimal levels and sources of protein in diets limit-fed to allow gain of 2.2 lb/day. Treatments were: a negative-control diet (urea; supplemented, 11.7% crude protein) and six diets containing either 13.5, 15.4, or 17.2% crude protein with either solvent-extracted (SSBM) or expeller-processed (ESBM) soybean meal, in which the soybean meal replaced corn in the control diet. Diets provided 75, 87.5, 100, or 112.5% of estimated crude protein requirement for a gain of 2.2 lb/day. The basal diet contained 83 ...

Evaluation Of The Protein Characteristics Of Four Diverse Grasses, C.P. Mathis, I.E.O. Abdelgadir, R.C. Cochran, J.S. Heldt, B.C. Woods, E.S. Vanzant, K. C. Olson, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Forage protein characteristics in four grasses were evaluated by the nylon bag method. All of the forages used (Bermudagrass hay, brome hay, forage sorghum hay, and prairie hay) were of relatively low quality, except the Bermudagrass, which was of average quality. The forages differed in the size of different protein fractions and in the rate and extent of protein degradation. Predicted extent of ruminal protein degradation (i.e., ruminal protein availability) was lowest for prairie hay, intermediate for Bermudagrass and forage sorghum hay, and highest for the brome hay.


Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Forage Sorghum Hay, C.P. Mathis, R.C. Cochran, B.C. Woods, J.S. Heldt, Gerald L. Stokka, E.S. Vanzant, K. C. Olson, Evan C. Titgemeyer Jan 1997

Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Forage Sorghum Hay, C.P. Mathis, R.C. Cochran, B.C. Woods, J.S. Heldt, Gerald L. Stokka, E.S. Vanzant, K. C. Olson, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Sixteen ruminally fistulated beef steers with ad libitum access to forage sorghum hay were used to evaluate the effect of increasing level of degradable intake protein (DIP) on forage intake and digestion. Forage OM intake and total OM intake were enhanced with increasing level of DIP supplementation. Similarly, increases in total OM digestibility and total digestible OM intake (TDOMI) were evident. Compared with the negative control, TDOMI was approximately doubled at the highest level of DIP supplementation.


Effect Of Urea Level In Protein Supplements On Performance By Beef Cows Consuming Low-Quality, Tallgrass-Prairie Forage, B.C. Woods, R.C. Cochran, C.P. Mathis, J.S. Heldt, K. C. Olson, Evan C. Titgemeyer, David M. Grieger Jan 1997

Effect Of Urea Level In Protein Supplements On Performance By Beef Cows Consuming Low-Quality, Tallgrass-Prairie Forage, B.C. Woods, R.C. Cochran, C.P. Mathis, J.S. Heldt, K. C. Olson, Evan C. Titgemeyer, David M. Grieger

Kansas Agricultural Experiment Station Research Reports

One hundred thirty two Hereford x Angus cows grazing tallgrass-prairie range during winter were used to evaluate the effects of varying the amount of supplemental degradable intake protein (DIP) derived from urea on cow and calf performance. Treatment groups were: 0, 15, 30, and 45% of the supplemental DIP from urea. Supplements were formulated to contain 30% crude protein (CP), with approximately 70% of the CP being DIP. Palatability was not a significant problem within the range of urea inclusion tested. In general, prepartum weight and condition losses were greater with increasing levels of urea, although the magnitude of condition ...


Economics Of Sealing Horizontal Silos, G.L. Huck, J.E. Turner, M.K. Siefers, B.E. Brent, K.K. Bolsen, Matthew A. Young, Ronald V. Pope Jan 1997

Economics Of Sealing Horizontal Silos, G.L. Huck, J.E. Turner, M.K. Siefers, B.E. Brent, K.K. Bolsen, Matthew A. Young, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Determining the value of silage saved by effectively sealing a horizontal silo requires only a few simple calculations, but it is still a concept that is often overlooked by many livestock producers who store large amounts of silage in that manner. Kansas produces about 3.0 million tons of silage annually, primarily from corn and sorghum. A majority of this silage is made and stored in either bunker, trench, or "drive-over" pile silos . Only 20 to 30% of these silos are sealed after filling. Producers who do not seal need to take a second look at the economics of this ...

Atp Bioluminescence Can Evaluate Cleaning And Sanitizing Effectiveness In The Milking Parlor, M. J. Meyer, Karen A. Schmidt Jan 1997

Atp Bioluminescence Can Evaluate Cleaning And Sanitizing Effectiveness In The Milking Parlor, M. J. Meyer, Karen A. Schmidt

Kansas Agricultural Experiment Station Research Reports

Four areas of the milking parlor were evaluated for effective cleaning and sanitation using total aerobic counts (standard plate count) and ATP bioluminescence (ATPB) techniques. Whereas the plate counts only monitor bacterial numbers, the ATPB results (reported as relative light units, RLU) also indicate residual soil or food residue on the surface. Results showed little correlation between the RLU values and the aerobic plate count data; however, the ATP bioluminescence system is a fast (<2 min) and simple method that evaluates the effectiveness of cleaning and sanitation procedures employed.; Dairy Day, 1997, Kansas State University, Manhattan, KS, 1997;


Biosecurity In The Dairy, Gerald L. Stokka, Thomas R. Falkner, Patrick Bierman Jan 1997

Biosecurity In The Dairy, Gerald L. Stokka, Thomas R. Falkner, Patrick Bierman

Kansas Agricultural Experiment Station Research Reports

Three strategies exist to control unwanted disease in a livestock operation: 1) prevent the douintroduction of infected cattle, 2) raise the overall level of resistance and specific resistance to infectious disease, and 3) minimize herd exposure to infectious disease. In addition, if unwanted disease exists in the herd, then a plan to eliminate the disease should be implemented. Maintenance of closed herds, testing procedures, vaccination schedules, sanitation, and good husbandry practices are integral parts of biosecurity procedures. The procedures in place should produce a benefit in terms of both economics and public perception that the quality and safety of our ...

Expeller Soybean Meal As A Source Of Rumen Undegradable Protein For Lactating Dairy Cows, John E. Shirley, D. Piehl, Evan C. Titgemeyer, Michael V. Scheffel

Kansas Agricultural Experiment Station Research Reports

The loss of meat and bone meal as a source of high quality protein for lactating cows creates an increased need for nonanimal sources. Fifty six Holstein cows were used to evaluate expeller soybean meal as a source of rumen undegradable intake (by-pass) protein for high producing cows. Expeller soybean meal tended to improve 3.5% contain fat-corrected milk yield and increased milk fat percentage relative to diets containing either solvent soybean meal or a meat and bone meal:blood meal mixture. In contrast, the protein percentage in milk was depressed significantly when cows were fed expeller soybean meal compared ...

Explaining Differences In Efficiency Among Dairy Operations, P. T. Berends, Michael R. Langemeier, Allen M. Featherstone

Kansas Agricultural Experiment Station Research Reports

To remain competitive, dairy operatoins need to continue to improve production efficiency and manage costs. Kansas Farm Management Association data from 1991 to 1995 were used to measure technical, economic, and overall efficiencies for 50 dairy operations in Kansas. On average, the farms showed .87 technical, .71 economic, and .67 overall efficiency. The latter was related negatively to labor, capital, feed, and fuel and utility expenses per cow. Veterinarian expenses were related positively to overall efficiency. Overall efficiency was the most sensitive to changes in feed expenses per cow, emphasizing the importance of controlling this cost. Results also indicated that ...

Kansas Agricultural Experiment Station Research Reports

Eighty-four crossbred gilts were used to exan1ine the effects of increasing dietary additions of poultry fat (PF) or choice white grease (CWG) on finishing pig growth performance, standard carcass characteristics, and longissimus muscle quality. Increasing CWG or PF improved feed efficiency. Increasing CWG tended to increase then decrease longissimus muscle visual color compared with longissimus muscles from those animals fed PF. Pigs fed CWG had firmer, less exudative, and more purplish-red (measured by a Minolta chronometer) longissimus muscles compared with pigs fed PF. Feeding CWG or PF did not affect standard carcass traits and had minimal effects on longissimus muscle ...
