The Effect Of Crowding On Growth Of The Cichlid Fish, Oreochromis Mossambicus, Bonnie A. Barrows

OES Theses and Dissertations

It has been reported that the Java tilapia, Oreochromis mossambicus, displays hypersensitivity to a substance it produces when biomass levels in a flow-through culture system exceed 20 g/1, resulting in reduced growth and high mortality. Experiments on the growth of this species in small tanks were conducted in order to determine whether O. mossambicus produces a growth-inhibiting compound under crowded conditions. This species was successfully maintained at biomass levels of 38 g/1 and 57 g/1 with a total mortality of only 4.5%.

The Java tilapia can grow rapidly in small aquaria, as indicated by the data taken during Experiment …

A Study Of The Action Of Bovine Cathepsin D On Intramuscular Connective Tissue, Elimosaria Elikalia Maeda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cathepsin D has been postulated to play a role in the tenderization of meat with ageing. Meat toughness has been related to connective tissue content and degree of myofibrillar shortening. This investigation was undertaken to determine the activity of cathepsin D on bovine intramuscular connective tissue.

Highly purified cathepsin D preparations from bovine spleen and bovine sternomandibularis muscle were obtained by ammonium sulfate fractionation followed by affinity chromatography on pepstatin coupled to controlled pore size alkyl amine glass beads. Maximum proteolytic activity using hemoglobin as substrate was obtained at pH 3.5 and 3.8 for bovine spleen and muscle cathepsin D, …

Sheep Diets And Feeding Behavior In Single And Common Use Grazing Trials On Southwestern Utah Summer Range, George B. Ruyle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of grazing trials were conducted on high elevation summer range near Cedar City, Utah. Cattle and sheep were stocked alone and in common in .4 hectare (ha) paddocks. Stocking rates were .76 ha/AUM in 1981 and .60 ha/AUM in 1982. Vegetation measurements were taken before and after grazing treatments to quantify vegetation disappearance. Diet samples were collected from esophageally fistulated sheep in the paddocks before grazing treatments were applied. After a predetermined level of forage utilization was achieved, the paddocks were re-sampled by the esophageally fistulated sheep to examine diets consumed from the forage-reduced vegetation. Behavioral observations were …

Nutrition And Feeding Behavior Of Goats And Sheep Grazing Deciduous Shrub-Woodland In Northeastern Brazil, James Alan Pfister

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of sheep and goats in the Brazilian Northeast is important for the livelihood of both subsistence and market-oriented producers. Seasonal nutritional stress on animals in the caatinga vegetational zone of this region causes periodic high mortality and chronically low productivity. Under such conditions, the survivability of goats has been higher than for other domestic livestock. Possible reasons for this include unique aspects of dietary selection and goat feeding behavior. The objectives of this research were to seasonally determine the botanical and nutritive content of goat and sheep diets, to determine forage intake by grazing goats and sheep, and to …

Electronic Feeding Doors For Individual Feeding Of Group Housed Sheep Compared To Individual Housing And Feeding Or Group Housing And Feeding, Ronald J. Lane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thirty-six mature purebred cheviot ewes and 36 polypaysired wether lambs were used in two separate experiments to determine the usefulness of an electronic feeding door as contrasted with traditional feeding situations. The sheep were stratified by weight into three management categories; group housing and feeding (G+G), individual housing and feeding (1+1), or group housing and individual feeding (G+1) using an electronic feeding door. The weight stratification formed a light and a heavy weight class resulting in a 3x2 factorial design. Two different training procedures were used to arrive at a generalized 14-day training sequence that does not require physical handling …

An Extension Teaching Demonstration Using Broiler Chicks As A Model, Joseph B. Ishaya

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This test demonstration was intended to develop a modern management program to improve broiler production in Nigeria through extension teaching methodology. The management programs included animal health, nutrition, and general care.

Some of the factors that limit broiler production in Nigeria are associated with the management strategy presently adopted by Nigerian subsistence farmers.

This report considers the effect of different protein sources on broiler nutrition and the techniques necessary to get the farmers to practice the result of up-to-date research findings.

The extension teaching demonstration reported here is based on 60 day-old chicks. Chicks were randomly assigned to two pens, …

Growth Of Targhee And Targhee Crossbred Lambs On Utah Rangelands, Holly Ann George

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Growth data were collected on 1848 Targhee and Targhee crossbred lambs from the Utah Agricultural Experiment Station flock at Cedar City for 1981 and 1982. The study objectives were to establish growth curves for seven lamb genotypes and examine within genotype growth differences among four grazing treatments (sheep alone, sheep and cattle mixed, both continuous and rotation).

Body weights were measured at birth, and at mean ages of 56, 120, and 154 (weaning) days of age. Linear, quadratic, and cubic regressions of weight on age were used to establish growth curves. Among genotype comparisons of entire growth curves were impossible …

Simulation Of Heterosis Effects On Costs Of Pork Production, G. L. Bennett, M. W. Tess, G. E. Dickerson, R. K. Johnson

Department of Animal Science: Faculty Publications

Individual plus maternal heterotic effects on swine production were simulated with a bioeconomic model by changing performance levels of eight traits: -8 d in age at puberty, +3% in conception rate, +.94 in pigs born/litter, +.035 kg in pig birth weight, +2.05 Mcal•sow^-1•d ^-1 in maximum milk output, +8% in preweaning survival, +10.8% in protein growth rate and +17.3% in fat growth rate. Associated heterosis simulated for other traits, such as weaning weights and postweaning gain/feed, was similar to experimental results. Effects of heterosis on biological (feed Mcal/kg) and economic ($/kg) costs were evaluated by simulating two- and …

Index Selection And Feed Intake Restriction In Swine, I: Effect On Rate And Composition Of Growth, Erik R. Cleveland, R. K. Johnson, R. W. Mandigo

Department of Animal Science: Faculty Publications

The objectives of this experiment were to determine the effects of index selection for increased average daily gain and decreased backfat, and the effects of restriction of daily feed intake, on rate and composition of growth in swine. A total of 53 barrows from select and control lines were randomly assigned to three feeding levels at 83 d of age, and 33 littermate barrows were slaughtered to establish initial body composition. The trial was approximately 105 d and the feeding levels were twice daily to appetite (AP), once daily feeding of 91% of appetite (AP9l) and once daily feeding of …

Index Selection And Feed Intake Restriction In Swine, Ii: Effect On Energy Utilization, Erik R. Cleveland, R. K. Johnson, R. W. Mandigo, E. R. Peo Jr.

Department of Animal Science: Faculty Publications

Fifty-three index select and control line barrows were randomly assigned to three feeding levels at 83 d of age. They were slaughtered at approximately 188 d of age to determine the effects of index selection (for increased average daily gain and decreased backfat) and level of feed intake on energy utilization. During the trial, the feed intake levels were twice daily to appetite (AP), once daily feeding of 91% of appetite (AP91) or once daily feeding of 82% of appetite (AP82) intake. The metabolizable energy intake required per kilogram of edible lean deposited (Mcal/kg) was reduced (P.75)^-1 x day …

The Effects Of Ethostasis On Farm Animal Behavior: A Theoretical Overview, A. F. Fraser, M. W. Fox

International Journal for the Study of Animal Problems

Ethostasis – the effect of constraining husbandry practices on animal behavior – is described and discussed. The review describes specific husbandry practices that may give rise to behavioral anomalies and how these anomalous behaviors may be of diagnostic value. Ready identification may facilitate correcting problems leading to lower productivity, diseases, and economic losses.

Too Much Of A Good Thing: Protein And A Dog's Diet, Dana Murphy

International Journal for the Study of Animal Problems

Murphy examines messages promoting the benefits of high-protein dog foods and then discusses the health effects of too much protein in a dog’s diet.

The Agricide Treadmill And Farm Animal Welfare, Michael W. Fox

International Journal for the Study of Animal Problems

The author cites publications that argue that agriculture in the United States is on a treadmill where farmers continually compete to reduce their food production costs. The consequence has been a reduction in farm animal welfare.

Too Much Of A Good Thing: Protein And A Dog's Diet, Dana H. Murphy

Pets Collection

Where the analysis done by Kronfeld on stress in dogs goes awry is in its implication that this conversion of protein reserves occurs during a mild or transient period of emotional turmoil. In point of fact, catabolism of proteins only begins after an extended duration of severe stress, as a consequence of an extreme condition like a long sled race or a bad infection. Therefore, a mildly stressed animal probably needs carbohydrates (and perhaps fats) far more than supplemental protein, since the former can be quickly and easily converted into bodily fuel. And in the case of the stress induced …

Prostaglandin F2a Induced Nest Building Behavior In The Non-Pregnant Sow, And Some Welfare Considerations, Judith K. Blackshaw

Agribusiness Collection

Nest building behavior, induced with intramuscular injections of prostaglandin F2_a (PGF2_a), was studied in non-pregnant sows. Acute effects, which included salivation, scratching, vomiting, defaecation and ataxia, were also recorded. Sows (Large White x Landrace) were housed in two different environments; six sows in bare pens and six sows in pens provided with bedding material. In all cases except one (bare pen) nest building sequences of differing intensities were recorded. Welfare suggestions include questioning the justification of using a drug (PGF2_a) in pig husbandry, which has unpleasant acute effects, and the suggestion that the provision of …

Furunculosis And Other Diseases Caused By Aeromonas Salmonicida, G. L. Bullock, R. C. Cipriano, S. F. Snieszko

United States Fish and Wildlife Service: Publications

Aeromonas salmonicida is a gram-negative bacterium that usually produces a water-soluble brown pigment. It was first described by Emmerich and Weibel (1890) as the cause of salmonid furunculosis in Germany. Although the disease was first considered to be limited to salmonids, studies by the Furunculosis Committee (Mackie et al. 1930, 1933, 1935) showed that A. salmonicida also infected other fish species. Present indications are that A. salmonicida or its variants also produce other diseases, such as ulcerative disease of goldfish (Carassius auratus), erythrodermatitis of common carp (Cyprinus carpio), ulcer disease of trout, and systemic infections among …

Infectious Pancreatic Necrosis (Ipn) Of Salmonid Fishes, Phillip E. Mcallister

United States Fish and Wildlife Service: Publications

Infectious pancreatic necrosis (IPN) is a viral disease principally associated with salmonids, although IPN and lPN-like viruses have been isolated from various nonsa1rnonid fish and marine invertebrates. Acute infection occurs in 1- to 4-month-old salmonids and can result in cumulative mortality approaching 100%. In contrast, fish 6 months old or older can undergo subclinical or inapparent infection, but experience no significant mortality. Survivors of the disease can become lifelong carriers of the virus. Epizootics of IPN have been reported worldwide, and several virus serotypes are recognized. The disease known as IPN was probably first described by M'Gonigle (1941) as acute …

Cranes Of The World: 6. Aviculture And Hybridization, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

The keeping of cranes in captivity, either as pets or as animals to be fattened for the pot, is evidently a very old practice. Captive cranes are depicted on the walls of the Temple of Deir-el-Barari of the Nile Valley, where cranes are shown walking in stately fashion between slaves. Each crane's bill is tied down close to its neck, which would upset its balance and thus prevent it from flying away (Whymper, 1909). Armstrong (1979) noted that cranes were apparently domesticated in ancient Greece, and that Plutarch (c. A.D. 46-c. A.D. 120) mentions the nesting of tame cranes, presumably …

Cranes Of The World: 7. Endangered Species And Conservation, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

Few families of birds, other than some associated with small island archipelagos, have such a large proportion of their species in danger of extinction as does the crane family. Of the 14 extant species of cranes, King (1979) regards two full species (whooping crane and Siberian crane) as endangered, three more (Japanese, hooded, and white-naped) as vulnerable, and the black-necked crane as of indeterminate status. Additionally, one race (the Mississippi) of the sandhill crane is classified as endangered, and the Cuban race is regarded as rare and local. Thus, more than a third of the world's crane species are currently …

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …

"Dried Fat" For Growing-Finishing Swine, K. E. Keaschall, B. D. Moser, E. R. Peo, Jr., A. J. Lewis, T. D. Crenshaw, Win Butler

Department of Animal Science: Faculty Publications

Three trials were conducted to determine the effect of "dried fat" (fats absorbed on carriers) in diets for growing-finishing swine. In trial I pigs receiving diets containing 5% added fat gained faster (.74 vs .71 kg/d), consumed less feed (1.87 vs 2.43 kg/d) and had a better feed efficiency (2.52 vs 2.88) than pigs fed diets without added fat (all P<.01). Pigs given the "dried fat" treatments gained faster (P<.01) and more efficiency (P<.01) than pigs fed the nonfat carrier counterpart. "Dried fats" containing whey plus fat and wheat bran plus fat produced similar performance to that observed with pigs fed a conventional tallow diet.

Growth And Activity Of Juvenile Mosquitofish: Temperature And Ration Effects, Wayne A. Wurtsbaugh, J. Cech

Watershed Sciences Faculty Publications

The effects of constant temperatures (10, 15, 20, 25, 30, and 35 C) and ration size on the growth rates and activity of juvenile mosquitofish Gambusia affinis (mean wet weight, about 20 mg) were measured in laboratory experiments. On ad libitum rations of Tubifex spp. worms, food-consumption rates of mosquitofish were very high, ranging from 7% dry body weight/day at 10 C to 83%/day at 35 C. Growth increased from 0% dry body weight/day at 10 C to 21%/day at 30 C and declined slightly at 35 C. Gross efficiencies (100 growth/food consumption) increased from 0 at 10 C to …

The Use Of Whole-Rolled Sunflower Seeds With Or Without Additional Limestone In Lactating Dairy Cattle Rations, Anne M. Finn

Electronic Theses and Dissertations

Thirty Holstein cows were utilized in a lactation trial evaluating diets containing whole-rolled sunflower seeds. Cows were randomly assigned to treatments, grouped according to previous milk production and lactation number. The cows were fed one of three diets: 1) the control was a com-soybean meal mix (CSM), 2) com-soybean meal mix plus 22% whole-rolled sunflower seeds, and 3) a corn-soybean meal mix with 22% whole-rolled sunflower seeds with an additional 3.5% limestone over SCS (SCL). Additional limestone was added in an attempt to form fatty acid insoluble soaps. Rations were formulated to be isonitrogenous at 16% crude protein, fed as …

Digestibility Of Sunflower Hulls Treated With Sodium, Ammonium, And Potassium Hydroxides, Bal Krishna Sharma

Electronic Theses and Dissertations

In vitro dry matter digestibility (IVDMD) of sunflower hulls (SFH) treated with sodium hydroxide (NaOH), ammonium hydroxide (NH₄OH), and potassium hydroxide (KOH) at increasing levels were studied. Tested concentrations of each alkali as percent dry matter (DM) on SFH were 1.63, 2.45, 3.26, and 4. 08. In vitro dry matter digestibility of sunflower hulls increased with higher concentrations of NaOH and KOH. Percent IVDMD for control (un-treated SFH) was 18.0. Percent IVDMD for SFH treated at 1.63, 2.45, 3.26, and 4.08% of DM were: 18.9, 21.4, 22.2, and 22.9 for NaOH; 18.3, 18.0, 18.3, and 18.5 for NH …
