Horse Safety Guidelines, U.S. Department Of Agriculture -- Extension Service

Nebraska 4-H Clubs: Historical Materials and Publications

The purpose of the National Horse and Pony Youth Activities Council is to help coordinate youth horse activities to obtain maximum benefit of the horse for developing youth. Since disregard of simple safety in handling horses can result in serious mishaps, knowledge and application of safety to riding is imperative to the purpose of the Council. Thus, the Council has developed guidelines to promote the safe use of the horse in an effort to improve the value of this animal in service to youth and society in general.

Growth In Weight Of Selected Organs, Tissues And Systems In The Pig, William J. Loeffel, Robert M. Koch

Nebraska Agricultural Experiment Station: Historical Research Bulletins

As a result of investigations at the Nebraska Agricultural Experiment Station in 1929, 1930 and 1931 to determine the effect of weight and degree of fatness of the pork carcass upon the quality and palatability of the meat, 40 pigs were slaughtered, five each at the approximate live weights of 70, 80, 90, 100, 115, 135, 160, and 180 kg. This corresponds to carcass weights ranging from 50 to 150 kg. The results of the meat investigations and feedlot data were reported elsewhere (Loeffel et al.,1943). This study reports data relative to the weight of selected tissues and organs, as …

Bats Of The Genus Myotis From Western Mexico, With A Key To Species, J. Knox Jones Jr., Hugh H. Genoways, Larry C. Watkins

University of Nebraska State Museum: Mammalogy Papers

Distribution and variation in Mexican representatives of the vespertilionid bat genus Myotis have not been well documented. The most complete modern systematic treatment of these bats is that of Miller and Allen (1928), although these authors examined relatively few specimens and some of their taxonomic conclusions have been modified by more recent studies (see especially Findley, 1960; Findley and Jones, 1967; Genoways and Jones, 1969). In the past two decades, field representatives of the Museum of Natural History at The University of Kansas have obtained large collections of mammals in western Mexico, principally in the states of Jalisco and Sinaloa. …

Influence Of Dietary Supplements Of Cholesterol And Vitamin D On Certain Components Of The Blood And Body Of Growing-Finishing Swine, M. H. Jurgens, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

The American public has been made extremely conscious of the concept that saturated fat and cholesterol may be involved in atherosclerosis in man. Likewise, because of their content of cholesterol and saturated fatty acids, animal products have become engrossed in a controversy concerning their role in the atherogenic process. No definite conclusions have been made in this area and until further research advances in the field of atherosclerosis, the animal scientist may have to concern himself with modifying the animal product in such a way that it will be more acceptable to the American public. The degree to which this …

A Summary Of Intergeneric New World Quail Hybrids, And A New Intergeneric Hybrid Combination, Paul A. Johnsgard

Papers in Ornithology

The exceedingly close affinities of the quail genera Colinus, Callipepla, and Lophortyx have been recognized for some time and have recently been emphasized by additional morphological (Holman 1961; Hudson et al. 1966), biochemical (Sibley 1960), and pterylographic (Ohmart 1967) evidence. Indeed, Holman has suggested that these three taxa might best be regarded as subgenera. Phillips et al. (1964) pragmatically merged Lophortyx with Callipepla; and Delacour (1961-1962) synonymized not only Lophortyx, but also Oreortyx and Philortyx, with Callipepla, yet retained Colinus as a separate genus. Although Ohmart (1967) questioned the validity of generically separating Lophortyx and …

1970 Nebraska Beef Cattle Report, J. L. Adams, E. F. Frolik, H. W. Ottoson, F. E. Eldridge

Nebraska Beef Cattle Reports

The use of high concentrate rations in finishing cattle has led to a rather high loss of livers due to abscesses.

The 1967 Statistical Summary of the Federal Meat Inspection Service of the USDA indicated the total number of cattle inspected was 27,859,980. Of these, 9.6% were condemned because of liver abscess. Considering the value of a liver to be about $3, the estimated loss to the industry because of condemnatIon due to abscess would be over $8 million annually.

The incidence of liver abscesses increases as the roughage level in a finishing ration decreases below 5% (Table I). The …

Effect Of Feeding-Fasting Interval On Finishing Pigs: Weight Gain, Feed Utilization And Physical And Chemical Carcass Measurements, T. L. Veum, W. G. Pond, L. Dale Van Vleck, E. F. Walker Jr., L. Krook

Department of Animal Science: Faculty Publications

Thirty-two Yorkshire pigs (49 kg body weight, 108 days of age) were used to determine the effect of feeding-fasting interval on rate of body weight gain, feed utilization and carcass and organ measurements at a slaughter weight of approximately 90 kilograms. Treatments were: (1) Continuous ad libitum feeding,(2) ad libitum 1 day, fasted on alternate days, (3) ad libitum 1 day, fasted 2 days, (4) ad libitum 1 day, fasted 3 days. Average daily gain was reduced progressively as severity of the fasting-feeding interval was increased. Efficiency of feed utilization, likewise, was reduced as the severity of feed restriction increased, …

Influence Of Dietary Supplements Of Vitamin D3 And Various Fats On Cholesterol And Fatty Acid Composition Of The Blood And Body Of Growing-Finishing Swine, M. H. Jurgens, E. R. Peo, Jr., P. E. Vipperman, Jr., R. W. Mandingo

Department of Animal Science: Faculty Publications

Previous work at this station suggested that vitamin D₂, when fed with or without dietary cholesterol, depressed blood cholesterol levels of swine (Jurgens, Peo and Vipperman, 1967) and rats (Jurgens, Blunn and Peo, 1968). While not proven to be the cause, blood cholesterol levels have been used as one of the main criteria to estimate the development of atherosclerosis in man (Rabinowitz, Meyerson and Wohl, 1960; Swell, Law and Treadwell, 1962). Several investigators have reported that supplementation of unsaturated fats (Ahrens et al., 1957; Okey and Lyman, 1957; Avigan and Steinberg, 1958; Peifer, 1966) and especially linoleic …

Diammonium Citrate And Diammonium Phosphate As Sources Of Dietary Nitrogen For Growing-Finishing Swine, G. F. Wehrbein, P. E. Vipperman Jr., E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Many scientists are concerned about the possibility Of a protein shortage in the near future. Since the pig will be placed in direct competition with man for many of the proteins presently used in feeds, it has become increasingly important to determine if other sources of nitrogen can serve as a replacement for some of the non-essential amino acid nitrogen in natural proteins.

Genetic Aspects Of Calving Ease, James S. Brinks

Department of Animal Science: Faculty Publications

Several trends in cattle production and marketing are becoming evident. Leaner and perhaps heavier muscled slaughter cattle will be in demand through the chain from consumers back through retailers, packers, feeders and finally the producers. Emphasis on growth in the feedlot will continue. Thus, the feedlot and carcass characteristics desired point towards fairly large, heavier muscled cattle. At the producer level, increased emphasis is being placed on matching cow size, milk level, and overall biological type to available resources. Thus, the trend for maternal herds in the Great Plains point towards an adapted, probably moderate size, and milking cow that …

Effect Of Feeding-Fasting Interval On Finishing Pigs: Blood Urea And Serum Lipid, Cholesterol And Protein Concentrations, T. L. Veum, W. G. Pond, E. F. Walker Jr., L. Dale Van Vleck

Department of Animal Science: Faculty Publications

A system of restricted feeding in which feed is entirely withheld for intervals of 24, 48 or 72 hr. following a 24-hr. period of ad libitum feeding in continuous sequence throughout the finishing period depresses weight gain and efficiency of feed utilization in direct relation to duration of the fasting period and has marked associated effects on carcass measurements, gland and organ weights and a small effect on fatty acid composition of the back fat (Veum et al., 1970). Cohn (1963) and Leveille and Hanson (1965, 1966) have shown marked changes in metabolism of nutrients and in body composition associated …

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

A New Genus Of Trematode (Digenea: Gorgoderidae) From The Ureter Of Tuna Fish (Thunnus Thynnus Maccoyii) In Australia, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

A large, digenetic trematode is described from the ureter of the tuna Thunnus thynnus moccoyii from southern Australian waters. It represents a new genus and species, Cetiotrema crassum (subfamily Gorgoderinae) distinguished by the size and shape of the body, the caeca being distant from the sides of the body, the uterus being intercaecal, the vitellaria arising as three claviform lobes on each side and the seminal vesicle at least partly anterior to the genital pore.

The genus is close to Phyllodistomum Braun; P. carangi Manter, 1947, is considered to belong to Cetiotrema; P. lancea Mamaev, 1968 is very similar …

Chiropteran Systematics, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Provides an overview of the field of chiropteran systematics in a way that will introduce the non-chiropterologist to the subject. By way of example, we have alluded to several aspects of taxonomic research at different levels in the hierarchy. Recourse to the publications cited at the appropriate places in the text will amplify our remarks and provide a solid background in the current work of the discipline.

Basically, taxonomic characters are where the taxonomist finds them; some, but not all, will prove useful also in elucidating relationships and evolutionary descent of taxa. Much remains to be done in these areas, …

Notes On Pocket Gophers From Jalisco, Mexico, With Descriptions Of Two New Subspecies, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Systematic, distributional, and ecological data are provided for seven taxa, two described as new, of three species of the pocket gopher genus Pappogeomys in the Mexican state of Jalisco. The first Jaliscan record of Orthogeomys grandis also is reported and several instances of sympatric occurrence of pocket gophers are documented.

Sire Effects In Different Housing Systems, G. R. Wiggans, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Over 1,000 Holstein herds in New York's Dairy Herd Improvement Cooperative were classified as to housing system. The two housing systems considered were stanchions and free stalls. First-lactation records (21,285) produced in these herds by daughters sired through artificial insemination were analyzed to determine if housing system would affect sire ranking. The study covered records started in 1964 through 1967.

The sire component of variance was estimated for each housing system for deviations of these records from their adjusted herdmate averages. The covariance between the means of daughters in each housing system was computed. The genetic correlation between sire effects …

Variation Within Herds Under Different Housing Systems, G. R. Wiggans, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

New York Holstein herds (1,152) including 75,875 cows were classified by housing system (stanchions, free stalls, and other combinations). Records initiated in these herds from 1964 to 1968 were used to determine the degree to which housing type might affect variance of milk production records in herds with 45 or more cows.

The within-herd variances by lactation for each housing system in each year-season were examined by Bartlett's test for nonhomogeneity among housing systems. Records in the stanchion systems were less variable than those in free-stall systems. This difference was not large enough to require adjustment for type of housing …

Holotypes Of Recent Mammals In The Museum Of Natural History, The University Of Kansas, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Various museums in recent years have published lists of type specimens housed in their collections. Such lists provide a useful point of reference for systematists and, for that reason, have been encouraged by the International Council of Museums. In 1968, that organization issued "A preliminary list of catalogues of type specimens in zoology and palaeontology," compiled by A. W. F. Banfield, and a revised list is planned for 1971. This catalogue of holotypes of mammals in the University of Kansas Museum of Natural History is particularly appropriate for the present volume, because Professor E. Raymond Hall was directly responsible for …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

Review Of Waterfowl In Australia By H. J. Frith, Paul A. Johnsgard

Paul Johnsgard Collection

Our dearth of knowledge concerning Australian waterfowl has, until recently at least, been so severe as to once stimulate Ernst Mayr to write a paper (Emu, 45:229-232, 1946) reminding Australians how little was then known about their native waterfowl. The situation was especially serious in view of the fact that no fewer than six of Australia’s 19 species of indigenous waterfowl represent monotypic genera that are largely or entirely restricted to that continent. Furthermore, these include such phylogenetically significant and taxonomically controversial genera as Anseranas, Cereopsis, Malacorhynthus, and Stictonetta, the last two of which have never been available …

Changes In Body Weight And Composition Of Adult Nongravid Female Rats Deprived Of Dietary Protein, W. G. Pond, L. Dale Van Vleck, E. F. Walker Jr., C. F. Eisenhard, J. R. O'Connor

Department of Animal Science: Faculty Publications

Seventy-six young adult nongravid female rats of the Carworth strain were used in two experiments to study the effect of dietary protein deprivation on body weight, feed consumption, body composition and serum protein concentration. Semipurified diets containing glucose, corn oil, vitamins and minerals with or without casein (protein-free = PF, 14% casein = C) were fed ad libitum in both experiments to rats caged in individual wire-bottom cages. Feeding the PF diet for up to 26 days resulted in a continuous weight loss over the entire period. The average loss in body weight as a percentage of initial weight of …

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

Relationship Between Type Traits And Longevity Of Daughters Of Hew York Holstein Sires, L. Dale Van Vleck, D. B. Filkins, H. W. Carter, C. L. Hart

Department of Animal Science: Faculty Publications

The percentage of 40 or more daughters having four lactations of 81 New York Holstein artificially insemination sires was correlated with the percentage of daughters in 66 type categories measured in the first lactation and their average first-lactation milk yield. Multiple regression on these type and production traits accounted for 92% of the variation in percentage of daughters having four lactations. A subset of 33 traits accounted for 82% of the variation. Traits with the largest standard partial regressions for longevity were milk production (.41), udder edema (.87 and .71), deep body (.53), medium upstandingness (.41), fore udder attachment (--.86 …

Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil

Papers in Behavior in Biological Sciences

The effects of CS1 duration, partial reinforcement, and trace conditioning on second-order conditioned suppression were investigated, employing 64 rats as Ss. In Experiment 1, the clearest second-order conditioning was obtained when CS1 duration was the same during both the first- and the second-order conditioning phases of the experiment. In Experiment 2, somewhat better second-order conditioning was obtained when first-order conditioning had been under conditions of partial reinforcement, delay CS-US pairing. In neither experiment were CS1 suppression and CS2 suppression during second-order testing well correlated. This aspect of the results raised the question of the influence of nonclassical conditioning factors on …
