G78-412 Guide For Controlling Insects On Pets (Revised December 1989), John B. Campbell, David L. Keith

University of Nebraska-Lincoln Extension: Historical Materials

This guide is restricted to the most common insect pests of cats, dogs, rabbits, birds, guinea pigs, and gerbils.

Pets, like all animals, are subject to attack by certain insects. Sanitation around the area where pets are kept, cleanliness of the pets, good care and nutrition all help reduce the chance of a serious problem.

G78-389 Nutrient Requirements Of Breeding Beef Cattle, James A. Gosey, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

The major nutrient requirements as listed in Tables 1a and b are modifications of similar tables published by the National Research Council, Nutrient Requirements of Beef Cattle, fifth edition. They have been (1) rearranged to emphasize "English" weights rather than metric; (2) modified so that daily nutrient requirements and the nutrient concentration recommendations are in closer agreement and (3) expanded to include estimated requirements for pregnant yearling heifers of heavier weight and 2 year old heifer nursing calves.

Genetic Method For The Preferential Elimination Of Females Of Anopheles Albimanus, J. A. Seawright, P. E. Kaiser, D. A. Dame, C. S. Lofgren

Entomology Papers from Other Sources

Recent field experiments demonstrated the possibility of using the sterile male method for the control of Anopheles albimanus Wiedemann, the most impor- tant vector of human malaria in Central America. Until now there was no practical method for excluding females from the releases of sterile males. A genetic method was developed for the preferential elimination of females during any of the four life stages. This genetic sexing system utilizes propoxur (o-isopropoxyphenyl methyl- carbamate) susceptibility as a recessive conditional lethal, a T(Y:2R) translocation, and an In(2R) inversion. The propoxur resistance allele (dominant) was linked to the Y chromosome via a radiation-induced …

Factors Affecting Twinning And Effects Of Twinning In Holstein Dairy Cattle, R. A. Cady, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Data were obtained from 23,978 calving records collected by the Eastern Artificial Insemination Cooperative's Calving Survey. The survey information included breed, parity and size of dam, date of breeding and birth, identification of sire and maternal grandsire, sex, size, and vigor of calf, and difficulty of birth. Due to small numbers of records for non-Holstein breeds, only Holstein records were used in the analyses. As parity increased, the incidence of twinning increased (P<.05). Month of birth (conception) and the size of dam measured within parity did not affect the twinning rate. The heritability of twinning, estimated using the genetic covariance between paternal half-sibs was .05 over all parities and within parity was .06, .03, and .03 for the first, second and third parities, respectively. Length of gestation for twins was 5 days less (P<.05) than for singles. In addition, twins were smaller and weaker, and their birth was accompanied by more dystocia than monoparous calves (P<.05). Neonatal mortality was four times higher (P<.05) for twins as compared to single births. In view of these facts, it does not appear that selection programs designed to increase twinning rates would be desirable for Holstein dairy cattle.

Breeding For Increased Protein Content In Milk, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The principles of selection are reviewed as a basis for discussing selection for protein content of milk. The correlations among components of milk will cause correlated responses in all even when selection is for only one component. Selection for fractional composition of fat or protein would lead to increases in content of fat and protein, but the expected increases in total yields of fat and protein would be much less than if selection were for yield of milk, fat, or protein. Selection should be for milk, fat, and protein yield with relative economic emphasis determined by the net economic value …

Nebraska Beef Cattle Reports

Retail value of wholesale meat cuts is influenced by quality and the proportion of lean, fat and bone. Wholesale cuts vary widely in value; for example, loins and ribs sell for more than rounds, rounds more than chucks, and chucks more than flanks, plates, or briskets. This value difference has prompted many attempts to find breeding and feeding systems that will increase the proportion of high-priced cuts.

Results shown here characterize the composition of carcass wholesale cuts from 14 breed combinations that were part of a cattle germ plasm evaluation program at the U.S. Meat Animal Research Center, Clay Center, …

The Complexity Of Measuring The Impact Of Possible Climatic Change On Agriculture, R. E. Neild

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Much geological and paleontological evidence exists of major changes in climate over widespread areas of the world including Nebraska. What is now Nebraska was once warm enough to support flora and fauna found now only in tropical areas. During the last Ice Age the climate of what is now Lincoln was similar to Igvitut at the base of the large glacier covering most of Greenland.

Recent weather fluctuations and consequent variations in essential food (Newman and Pickett, 1974), fuel, and water supplies have prompted speculation that climate is changing toward some former extreme. Massive purchases of grain by the Soviet …

Major Issues Facing Agriculture As Our Nation Moves Toward A Domestic And International Food And Agricultural Policy, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

It is a pleasure for me to speak this evening before such a distinguished group of agribusiness and academic representatives, all of whom have a common interest. Twenty years ago, that interest would have been denominated as "agricultural policy". Today it would be called "food policy", which presumably is a broader term. Food policy is usually defined to encompass the interests of everyone in the production and marketing process from producer to consumer. It is by no means limited geographically, but encompasses people and firms who are involved -- directly or indirectly, domestically and internationally - in the food business. …

Morphometric Variation In The Tropical Pocket Gopher (Geomys Tropicalis), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The tropical pocket gopher (Geomys tropicalis). which exhibits no chromosomal or genic variation, was examined for variability at the morphometrical level. Univariate and multivariate analyses were used to determine age, sexual, and geographical variation. Significant differences were found between different age classes and between sexes. The amount of individual variation was comparable with other rodents and did not exhibit the reduced variation expressed at the chromosomal and genic levels, G. tropicalis is considered to be a monotypic species.

The Extrafloral Nectaries Of Ipomoea Carnea (Convolvulaceae), Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

lpomoea carnea (Convolvulaceae) possesses two types of extrafloral nectaries, located on the petiole and on the pedicel. These secrete a complex nectar containing sugars and amino acids. The insects attracted to the extrafloral nectaries are predominantly ants and they are relatively abundant throughout the year. A number of incidents of plant defense as a result of the presence of extrafloral nectary visitors at the extrafloral nectaries of I. carnea were observed and are consistent with the ant-guard theory of the function of extrafloral nectaries.

Herpetomonas Megaseliae And Crithidia Harmosa: Growth On Blood-Agar Plates, Amy Doran Kepel, John J. Janovy Jr.

John J. Janovy, Jr. Publications

A technique for culturing two species of trypanosomatid flagellates on blood-agar plates is described. Herpetomonas megaseliae and Crithidia harmosa were grown as discrete clone colonies on plates prepared in sterile petri dishes with a medium derived from that of Tobie et al. (1950, J. Parasitol. 36: 48-54). Plates were inoculated with 0.01 ml flagellate suspension and the inoculum was spread evenly over the surface of the agar with a sterile glass spreader. Plates were incubated in a high humidity chamber at 25 C and colonies of both species, easily visible to the unaided eye, appeared within 1 week. There was …

Foods Of Juvenile, Brood Hen, And Post-Breeding Pintails In North Dakota, Gary Krapu, George Swanson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Pintail (Anas acuta) is a common to abundant nesting species in North Dakota, becoming more numerous during years of favorable water conditions and less so during drought. Stewart and Kantrud (1974) estimated breeding-populations of 304,000, 111,000 and 379,000 pairs in the Prairie Pothole Region of North Dakota during 1967-69, respectively. We studied food habits of juvenile and adult Pintails during the brood-rearing and post-breeding periods in North Dakota to learn their food requirements during these phases of the life cycle. Food habits of flightless juveniles have been studied in Alberta (Sugden 1973) and limited information on downy …

Aboriginal Exploitation Of Marine Food Resources, Alan J. Osborn

Department of Anthropology: Theses and Student Research

Anthropological interest in human exploitation of resources has increased considerably during the last decade. Archaeological and ethnological literature concerning man's utilization of the world's oceans is relatively abundant and there are now several on-going anthropological research programs, e.g., Aleutian Islands, Pacific Northwest Coast, California, Hawaii, Australia, New Zealand, Peru, Ecuador, Chile, and Southern Africa which focus primarily on maritime adaptations. The purpose of this study is threefold: (1) to suggest that anthropological assumptions regarding marine food resources and their use are inadequate; (2) to examine marine ecosystems with respect to structure and dynamics, primary productivity, ecological efficiencies, distributional and quantitative …
