Evaluation Of Urea And Dried Whey In Diets Of Cows During Early Lactation, David Paul Casper

Electronic Theses and Dissertations

Previous research indicated that soluble nitrogen may be utilized more efficiently for rumen microbial production in diets containing dried whey. To further evaluate this, 33 Holstein, cows (30 multiparous and 3 primiparous) were fed one of three concentrate mixes containing all natural proteins (SBM). 1% urea (U), or 1% urea and 30% dried whey (UDW) from wk 3 through 16 postpartum. Urea replaced portions of the soybean meal in the SBM mix while dried whey replaced portions of the corn and soybean meal. Cows were fed total mixed rations consisting of 40% (dry matter basis) corn silage, 10% alfalfa hay, …

Bobwhite Thesaurus, Thomas G. Scott

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

The Bobwhite Thesaurus was assembled with the belief that it  would make the voluminous literature more accessible. Publications  on the bobwhite have become so numerous and have been published  in so many different places that today's bobwhite researcher is seldom able to conduct the library search required to unearth all pertinent material. This results in failure to acknowledge and use prior  findings.

An effort has been made to seek out and index all publications  issued prior to 1983 that contain information on the bobwhite. All  publications found have been included irrespective of their apparent  worth excepting anonymous papers. Publications which …

Isolation Of Lactoferrin And Its Concentration In Sows’ Colostrum And Milk During A 21-Day Lactation, J. I. Elliot, B. Senft, G. Ernhardt, D. Fraser

Nutrition Collection

Levels of lactoferrin, an Fe-binding protein with bacteriostatic properties, were determined in the colostrum and milk of Yorkshire sows during a 21-d lactation. Lactoferrin levels averaged 1,100 to 1,300 μg/ml near the time of farrowing, then declined sharply during the first week of lactation. Concentration of lactoferrin showed considerable variation among sows, but not among teat positions (anterior to posterior). A method for isolating high purity swine lactoferrin is described.

Chemical Composition And Acceptability Of Rain Damaged, Field Dried Alfalfa Hay, Cesar Augusto Araque H.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water was applied to swaths of cut alfalfa forage with oscillating sprinklers to stimulate rain damage to field drying alfalfa hay to determine the changes in chemical composition, loss of yield, and acceptability of rain damaged hay to sheep. An additional objective was to develop models to estimate yield losses form experimental hay. The experimental hay was prepared with a 2x2x4x4x2 factorial design. The factors were two different cuttings (July and September), two width of swath (3.05 m and 4.27 m), four times of applying artificial rain (3h, 8h, 13h, and 24h after cutting), four levels of artificial rain (no …

Combined Scale Weight, Height At Hips And Visual Condition Score As An Indicator Of Functional Body Size In Range Cows, Patricia B. Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thirty-five range cows of various breeds were obtained for the study. Body measurements taken were live weight and hip height and all cows were condition scored for level of fatness. The cows were slaughtered and the following morning several carcass measurements were taken and the plate was removed from the left side. These plates were boned and the remaining flesh ground for chemical analysis of percent carcass fat. Regression equations were calculated for estimating percent carcass fat from condition score, weight:height ratio and hip height (R²=.765). However, condition score alone is the single best estimator for percent carcass …

Influence Of Breed Type, Milk Production Potential And Cow Size Upon Maintenance Requirements, Jacqueline Lee Kennedy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two biological types of cows, straightbred Herefords (HxH) and Simmental-Hereford crosses (SxH), of similar body condition were individually fed over a 10 week period to compare the biological types for maintenance and to determine the influence of milk production potential and of size. Cows were nonlactating and in the last part of the first trimester of pregnancy. During the first 5 weeks of the feeding experiment, one-half of each type was fed 75% of estimated maintenance while the other half was fed 125% of estimated maintenance. During the last 5 weeks of the experiment those fed at 75% of maintenance …

Range Beef Cattle Productivity In Southern Utah, Mouslim A. Maiga

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-six range beef cattle ranches in southern Utah were surveyed by personal interview to obtain production data. The data were used to characterize the level of production efficiency in terms of calving rate, weaning rate, weaning weight, and net weaning weight in these operations; and to identify factors associated with differences in productivity.

The data revealed that productive efficiency was generally lower than the potential.

Mean calving rate of cows exposed for breeding was 83.4%. Stepwise regression involving calf death losses at or shortly after birth and heifer replacement rate accounted for 98.3% of the variance in calving rate. Calving …

Invertebrates Consumed By Dabbling Ducks (Anatinae) On The Breeding Grounds, George A. Swanson

Journal of the Minnesota Academy of Science

Foods consumed by dabbling ducks on the breeding grounds of south-central North Dakota were investigated during the spring and summer of 1967-80. Invertebrates dominated the diet of laying females. Animal foods comprised 99%, 72%, and 77% of the diet of laying blue-winged teal and northern shovelers, gadwalls, and mallards, and northern pintails, respectively. Factors that influence food selection include morphological adaptations for feeding, current physiological demands, the nutritional value of food items, and food availability. Preservation of waterfowl production habitat requires that the value of the wetland complex be recognized. Temporary, seasonal, and semi permanent wetlands provide abundant and highly …

Potential Effects Of Insecticides On The Survival Of Dabbling Duck Broods, Patrick W. Brown, Malcolm L. Hunter Jr.

Journal of the Minnesota Academy of Science

The effect of insecticides on the survival of dabbling duck broods was investigated by reviewing studies of natural brood survival and depression of growth rates for ducklings raised on wetlands treated with insecticides. Ducklings raised on an insecticide-treated wetland took 5 days longer to reach the normal 14-day body weight. Normal brood mortality for three species of dabbling ducks was highest in the first two weeks of life and ranged from 25% to 51%. High mortality of young ducklings is probably related to their small size. Thus, mortality rates could be in creased to 35% to 70% because of the …

The Effects Of Regulation On Aquaculture Development, Derek S. Busby

Marine Affairs Theses and Major Papers

A comparative study of the regulatory frameworks surrounding aquaculture in the states of Florida, Mississippi, and Rhode Island is conducted beginning with a generalized study of basic legal premises of aquaculture-related law common to each state. This is followed by a detailed study of the statutory authority for aquaculture regulation and the agencies which control aquaculture activities in each state. In conjunction with the law analysis an Index of Specialization (ISP) study is conducted for each state to determine a relative ranking of diversity of crop production relative to each state’s overall aquaculture production.

Marine Resources: The Presentation Of A Business Plan, K. Scott Colby

Marine Affairs Theses and Major Papers

The once questionable technology of hatchery production has become routine and, with the recent development of up-welling techniques, is more effective and efficient. The supply of natural shellfish and fishery stocks is on the decline and this trend is expected to continue. Aquaculture has been the solution to this problem in many European countries and the United States is currently attempting to remove domestic obstacles through its National Aquaculture Plan. The proprietor has experience in the production of various marine invertebrates and has designed, built and operated a producing shellfish hatchery. By using a unique up-welling juvenile culture system a …

Fisheries Report No 63 - Assessment Of Artificial Feeds For Battery Culture Of A Freshwater Crayfish, Marron (Cherax Tenuimanus) (Decapoda: Parastacidae), Dr N. Morrissy

Fisheries Research Reports

Performance of juvenile crayfish, 0.1-5 g, on a variety of commercial crustacean feeds was tested under conditions of individual housing ("battery culture"), where sources of additional feed were minimized (detritus), or eliminated (cannibalism) Survival was close, or equal, to 100% over 50 day test periods, a reflection of optimal battery conditions rather than feeding, since survival over 100 days for an unfed (control} group was also 100%. No ecdysiad mortality, or trauma, occurred with crayfish, up to 10g, in compartments of area 75 cm. Growth performance in tests was rated by separate ratios for ecdysial increment and frequency, relative to …

Effect Of Various Dietary Arginine: Lysine Ratios On Performance, Carcass Composition, And Plasma Amino Acid Concentrations Of Growing-Finishing Swine, L. C. Anderson, A. J. Lewis, E. R. Peo, Jr., J. D. Crenshaw

Department of Animal Science: Faculty Publications

Crossbred growing-finishing pigs (112 barrows, 48 gilts) were used to determine the effect of reducing excess dietary arginine, through feedstuff variation, on performance, carcass composition and plasma amino acid concentrations. Diets contained five, four, three or two times the NRC requirement for arginine. Lysine in all diets was formulated to be equal to NRC requirements, and all diets contained at least 100% of the NRC recommendations for all other essential amino acids.

Protecting Off-Shears Sheep In Adverse Weather, T M. Ellis

Journal of the Department of Agriculture, Western Australia, Series 4

In January 2982 in the Narrogin-Darkan area of Western Australia, about 14,500 sheep up to 40 days off-shears died after a 48-hour period of heavy soaking rain that followed a thunderstorm three days previously. An estimated 100,000 sheep died throughout the South-West at the time.

P. G. Buckman - at the time Department of Agriculture District Veterinary Officer, Narrogin - surveyed 17 properties in the area. He found that losses in unshedded sheep 0 to 40 days off-shears ranged from 0 to 84 per cent of sheep on the property with an overall average of 27.9 per cent. Rainfall in …

Effect Of Suckling And Ovariectomy On The Control Of Luteinizing Hormone Secretion During The Postpartum Period In Beef Cows, M. Garcia-Winder, K. Imakawa, M. L. Day, D. D. Zalesky, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

Twenty-two mature pluriparous beef cows were randomly assigned to one of six treatments in a 2 x 3 factorial experiment in order to study the role of suckling and ovarian factors on control of the tonic and episodic release of luteinizing hormone (LH). Twelve cows remained intact (INT) and 10 were ovariectomized (OVX) within 4 days following the day of parturition (Day 0). The suckling intensities were nonsuckled (0), suckled once daily for 30 mm (1) and suckled ad libitum by two calves (2). Blood samples were collected at 1 5-mm intervals for 6 h weekly, from Days 6 to …

The Nutritional Value Of High Moisture And Reconstituted Sorghum Grain For Swine, J. D. Crenshaw, E. R. Peo, Jr., A. J. Lewis, B. D. Moser, T. D. Crenshaw

Department of Animal Science: Faculty Publications

A growing-finishing experiment involving 150 crossbred swine (replicated by time) and two metabolism experiments involving 36 crossbred barrows were conducted to determine the nutritional value of harvested high moisture (HMSG), reconstituted (RCSG) and dry sorghum grain (DSG) for swine. In Exp. 1, pigs fed HMSG diets gained the same, consumed similar amounts of feed, but less (P<.05) crude protein (equivalent dry matter basis) and had better (P<.05) feed conversion than pigs fed DSG diets.

Environmental, Nutritional, And Physiological Factors Associated With Hoof Growth And Wear In Holstein Cows, Lisa Hartson Bemis

Electronic Theses and Dissertations

Environmental, nutritional, and physiological parameters associated with hoof growth and wear were evaluated using data from 140 Holstein cows in five herds. Growth and wear of the dorsal and lateral regions of the front and rear outside claws were measured at approximately 2 mo intervals over a 14 mo period. Housing facilities varied from continuous confinement on concrete to confinement in dirt lots and included loafing sheds, free stall barns, and one comfort stall facility with rubber mats. Lateral hoof regions grew 24% faster than dorsal regions in the front and 20% faster in the rear hooves. Rear hooves grew …

Enteric Redmouth Disease Of Salmonids, G. L. Bullock

United States Fish and Wildlife Service: Publications

Enteric redmouth disease (ERM) is a systemic bacterial infection of fishes, but is principally known for its occurrence in rainbow trout, Salmo gairdneri. The disease was first reported in the 1950's by Rucker (1966), and in recognition of that fact, the causal organism was named Yersinia ruckeri by Ewing et al. (1978). Although Wagner and Perkins (1952) described a bacterial disease that produced a red-mouth condition in rainbow trout in California and Colorado, it was caused by a different bacterium; they isolated Pseudomonas hydrophila rather than Y. ruckeri.

The Effects Of Calcium Hydroxide Treatment Of Sunflower Seeds On Ration Digestibility And Rumen Parameters In Holstein Steers, Ann C. Spearow

Electronic Theses and Dissertations

Digestibilities of rations containing 10% (dry matter basis) oil-type, rolled sunflower seeds treated with three levels- of calcium hydroxide were compared using .a randomized complete block design. Forty-eight Holstein steers were fed one of six completely mixed rations consisting of (DM basis) 44% corn silage, 10% chopped alfalfa hay, and 46% concentrate mix. Concentrate mixes contained: CSM = control; SCS =control+ 22% sunflower seeds; SCL = SCS + 3.5% additional limestone; SCH2, SCH4, and SCH8 = SCS + 2, 4, and 8% calcium hydroxide (% sunflower seed DM), respectively. Total rations were isonitrogeneous at approximately 16% crude protein and isocaloric …

A Report On A Pilot Study On Cattle Grazed Patches In Herbaceous Vegetation, Victor Povilaitis

Undergraduate Honors Capstone Projects

Since the late 1960's, the term station (Goddard 1968), feeding station (Novellie 1978, Underwood 1982), and feeding site (Underwood 1983) have been used to describe the area in front of a foraging animal in which it can access forage without moving its front legs. The area is a hypothecial semicircle in front of the grazing animal, but the vegetation actually impacted by defoliation may be considered a "grazed patch," which may be the sum of several feeding stations. As animals graze the vegetation in an area, grazed patches are created. Presently, it is undocumented if such patches influence the behavior …
