Evaluation Of Sires Available Through Planned Mating, L. Dale Van Vleck, C. R. Henderson, H. W. Carter

Department of Animal Science: Faculty Publications

There is some concern that methods of sire evaluation which utilize contemporary stablemate averages can be biased by differential genetic merit of the mates of these sires. A little reflection, however, indicates that even if the cows to which some sires are mated are more highly selected than the mates of other sires, this differential merit will not affect seriously the ranking of sires according to the evaluation of their progeny. Until the present, data have not been readily available with which to study the seriousness of this problem. The present study does not deal with the question generally, but …

Sire Evaluation From Five-Month Daughter Records, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The chief advantages of sire evaluation based on five-month daughter records are: 1. Genetic progress is inversely proportional to the turnover rate in testing bulls so that if this interval is shortened by 10%, the rate of genetic progress will be increased by 11%. The turnover period can be shortened with the use of 5-month records from about 50 months to 45 months—a decrease of 10% in time. 2. Genetic progress is also related to how many top bulls are saved and how many poor ones are culled out of all those sampled. In other words, the more bulls tested …

Effect Of Levels Of Meat And Bone Scraps On Growth Rate And Feed Efficiency Of Growing-Finishing Swine, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Many investigations have shown that soybean meal when properly supplemented can replace meat and bone scraps as a major source of protein in swine rations (Lepley et al., 1950; Terrill et al., 1954; Rohlf, 1954; Meade and Hanson, 1957; Meade et al., 1958; Becker et al., 1960). The importance of this finding is emphasized by the work of Bloss et al. (1953), Terrill et al. (1954), Meade and Teter (1957) and Becker and Jensen (1961) who reported a significant depression in growth rate and feed efficiency of swine fed rations containing relatively high levels …

Parameters For Milk Yield And For Percents Of Ash, Dry Matter, Fat And Protein In Sows, W. G. Pond, L. Dale Van Vleck, D. A. Hartman

Department of Animal Science: Faculty Publications

Milk was collected separately by machine from four to six glands on nine Yorkshire and Berkshire sows 2 or 3 days after farrowing and at weekly intervals throughout 6 weeks of lactation. Milk yield was measured following intramuscular injection of oxytocin, and the percent of ash, dry matter, fat and protein in the milk from each gland was determined. The average milk yield per gland, following a 1-hour period during which the pigs had been removed from the sow reached a peak of 74.6 gm. 3 weeks after farrowing. The ash content was 0.79% 2 or 3 days after farrowing, …

Nebraska Beef Cattle Reports

Feeding pastured calves protein supplements weekly instead of daily during the winter made little difference in either winter or summer gains, according to research results to date.

Two sources of protein were used in the trial. (I) Second cutting alfalfa hay was fed at the rate of four pounds per head daily. One group of calves was fed four pounds per head daily and one group was fed 28 pounds per head once each week. (2) Forty percent protein, pellets or cake, was fed at the rate of one pound per head daily. One group was fed one pound per …

Review Of Sex Ratios And Age Ratios In North American Ducks, Paul A. Johnsgard

Papers in Ornithology

This bulletin is by far the most elaborate and comprehensive of any of the publications dealing with waterfowl age and sex ratios that have appeared to date, and represents the presentation and analysis of sex and age ratio data accumulated by the Illinois Natural History Survey over the last 24 years. The several people concerned are to be congratulated for bringing this material into publishable form, and it is commendable that the National Science Foundation undertook the printing costs of this extensively tabulated and illustrated bulletin.

Studies On Parorchis Acanthus (Trematoda: Digenea) As A Biological Control For The Southern Oyster Drill, Thais Haemastoma, Nelson R. Cooley

United States Fish and Wildlife Service: Publications

Events in the attack on the southern oyster drill, Thais haemastoma, by miracidia of the digenetic trematode, Parorchis acanthus, are described.

Infection rates in wild drill populations of various Gulf Coast localities from Florida to Texas were low, but intensity of infection in individual drills was high and caused castration. Infection rates in laboratory experiments were high, but intensities were low.

Pathology of natural infections in drills is described. The infection lasts at least two years, possibly even for life.

Natural infection rates of juvenile herring gulls (Larus argentatus) , ring-billed gulls (L. delawarensis), and …

Improvement Of Beef Cattle Through Breeding Methods. Summary Of Results From Regional Project Nc-1, Keith E. Gregory

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The major purpose of this project is to obtain information that beef cattle breeders can use to make maximum genetic improvement in all traits of economic value in beef cattle. The major objectives of NC-1 are the following: (1) to determine the traits of economic importance in beef cattle: (2) to assess their relative value; (3) to develop reliable methods and procedures for measuring and evaluating them; (4) to obtain estimates of their heritabilities; (5) to obtain estimates of the genetic and phenotypic correlations among all economically important traits; (6) to evaluate the effects and uses of inbreeding and heterosis; …

The Sexual Behavior And Systematic Position Of The Hooded Merganser, Paul A. Johnsgard

Papers in Ornithology

It has been over 15 years since Delacour and Mayr (1945) first urged that the mergansers (Mergus)and the goldeneye-Bufflehead group (Bucephala) be merged into a single tribe (Mergini) rather than being maintained in separate subfamilies (Aythyinae and Merginae). Their reasons for this change were several, and included such points as the similarities in the downy young, female color patterns, occurrence of wild hybrids between the two genera, and tracheal structure. Indeed, except for the shape of the bill in these two groups there is no good means of distinguishing the two subfamilies. As Delacour and Mayr pointed out, bill shape …

A Histological Study Of The Postnatal Development Of The Bovine Testis, R. G. Fossland, A. B. Schultze

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A limited number of detailed studies on the development of the bovine testis from birth to sexual maturity have been reported. Further study of bovine testis development appears desirable to furnish additional observations and to note variations that may occur during the developmental process. Information on the process of spermatogenesis should furnish a basis for experimental work designed to promote increased spermatogenic activity in the postpubertal testis as well as for work directed toward promoting complete spermatogenesis at an earlier than usual age. This report is a study of the histological picture of the testes from 56 bulls varying from …

Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Body weight is the one measurement most extensively used to evaluate growth, condition, and value for beef, and as a basis for calculating feed requirements for cattle. Weight can be determined readily by scales but unfortunately scales of a capacity adequate for weighing cattle are not always available. Thus there is a real need for a basis of estimating weight from some body measurement that can be obtained easily and at a minimum of cost and time. It is the aim of this study to utilize additional data now available to increase further the accuracy and reliability of estimating weight …

Correspondence About "Evolutionary Relationships Among The North American Mallards", Allan R. Phillips, Paul A. Johnsgard

Papers in Ornithology

The confusing leading article of the 1961 Auk calls for comment. Despite his title, "Evolutionary Relationships among the North American Mallards," the author discusses primarily geographic distributions, population sizes, egg-white proteins( !), and certain behavioral patterns. Maps are based on ". . . the literature, personal communications, and the major United States collections," " . and from additional sight and specimen records available to me"; yet only two museums other than Cornell University are mentioned in the acknowledgments. These maps show many records of platyrhynchos far to the south; sometimes (Figure 1) the reader must search hard for any hint …

Wintering Distribution Changes In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Through the use of data compiled by the Audubon Society's annual Christmas Counts, an attempt has been made to trace the distributional changes of wintering Mallards and Black Ducks in the eastern states from 1900 to the present. During this period the Black Duck has increased relative to the Mallard in few if any states (the Great Lakes region), whereas the Mallard has increased nearly everywhere else (except in the extreme northeast), particularly in the southern coastal states. Deforestation and changes in land use are sug- gested as probable reasons for this trend, which is not likely to be reversed.

49th Annual Feeders Day Progress Report: Improving Beef Production Through Nutrition And Management, E. F. Frolik, A. W. Epp

Nebraska Beef Cattle Reports

The science of nutrition has come into its own in the last few years. Greater recognition of the value of protein, the identification of new nutrients and the awareness of the importance of nutrition to health have been part of this trend.

In this new era in nutrition, beef has been found to be one of our most nutritious foods. Not only does it contain a generous amount of protein, but its protein is of high quality, too. In addition, beef supplies important minerals such as iron and phosphorus, which contribute to healthy blood and sturdy bones. The essential B …

Components Of Variance Associated With Milk And Fat Records Of Artificially Sired Holstein Daughters, L. Dale Van Vleck, L. H. Wadell, C. R. Henderson

Department of Animal Science: Faculty Publications

Components of variance are estimated for the three-way classification analysis of variance of DHIA reported first and second milk and fat records of artificially sired Holstein cows and of Owner-Sampler reported milk and fat records of artificially sired Holstein cows. The total variance of milk and fat records is partitioned into the following components with the approximate percent of total variance: sire, 6%; year-season, 2%; herd, 30%; sire by year-season, 0%; sire by herd, 1–2%; herd by year-season, 6–8%; sire by herd by year-season, 1–7%; and residual, 50%.

Swine Brucellosis: How You Can Eradicate It

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Swine brucellosis is a bacterial disease that affects swine, other domestic animals, and humans. Severe exposure causes the disease in cattle, dogs, cats, and poultry. The disease can spread from one species of animal to another, and from animals to humans. However, it does not normally spread from one human to another, or from humans to animals. The disease costs the swine industry about $10 million a year. Losses due to human infection cannot be estimated. Although human brucellosis, or undulant fever, is difficult to diagnose-especially in mild cases-a total of 892 cases were documented in the United States in …
