Effect Of Proportion Of Concentrates In Herd Ration On Lactation Curves, G. R. Wiggans, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The proportion of net energy in the herd's ration derived from concentrates as reported to Dairy Herd Improvement was the basis for defining five groups of milk production records from New York and New England. The relative daily milk production by season and stage of lactation was estimated for each group at two ages by a generalized least squares procedure. These solutions showed little variation due to the grouping by proportion of concentrates, but season of freshening and age were important. The mean yield did increase with an increasing proportion of concentrates, and, consequently, extension factors would differ by group …

Genetics Of Dairy Goats: A Review, M. U. Iloeje, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The literature on genetics of dairy goats was reviewed to point out not only world wide research but also the need for research in the United States to achieve the goal of uniform national genetic evaluations similar to those now available for dairy cattle. The number of breeds studied and the variety of research are remarkable. The numbers of animals and records involved in most studies, however, suggest large sampling variances of estimates.

Effect Of Energy Source Prior To Parturitian And During Lactation On Piglet Survival And Growth And On Milk Lipids, R. Dean Boyd, B. D. Moser, E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Two experiments were conducted to determine the effect of level and source of energy fed to sows prior to parturition and during lactation on birth weight, gain, and survival of piglets and fat content of the dam's milk.

Food Deprivation And The Regulation Of Meal Size In Larvae Of Chrysopa Carnea, Alan B. Bond

Alan Bond Publications

The course of repletion and the effects of food deprivation on meal size were explored in three experiments on larvae of Chrysopa carnea (Neuroptera). Feeding to repletion was found to occur within the first 30 min of exposure to food. Meal size increased as an ogival function of deprivation, up to the limit of gut capacity. Behavioral components involved in the initiation of feeding were little affected by deprivation and did not appear to be inhibited by distention of the gut. Termination of a meal may be mediated by the stimulation of prey-release behavior, rather than by inhibition of feeding.

Studies On The Feasibility Of Predicting Feedlot Performance From Certain Laboratory Grain Analyses, M. L. Galyean, D. G. Wagner, R. K. Johnson

Department of Animal Science: Faculty Publications

Data from 14 cattle feeding trials were utilized to study the relationship between several laboratory analyses and animal feed intake (INTAKE), gain (ADG) and feed efficiency (F/G). Laboratory analyses considered were 6, 12 and 24 hr in vitro dry matter disappearance (IV6, IV12, IV24, respectively); in vitro gas production in 1 hr and 6 hr (GP1 and GP6, respectively); and degree of gelatinization (GEL). A multiple regression equation with variables for treatment and trial classification, initial weight and the quadratic effect of initial weight was fit to the data. The effect of initial weight was significant for all three performance …

The Hollow Of Echoes, Kathleen Danker, Felix White Sr.

Department of English: Faculty Publications

The Hollow of Echoes is the result of collaboration between Mr. Felix White, Sr. and myself. Mr. White, who resides in Winnebago, Nebraska, is knowledgeable in many areas of traditional Winnebago culture including language, history, legends and law. During the spring of 1973, he recounted to me a number of Winnebago legends of which I made recordings. I have incorporated these legends into a fictional account of a present-day Winnebago grandfather using the stories to instruct his grandchildren in traditional ways of viewing situations they encounter in their daily lives. Almost all of the views of the grandfather in the …

G78-417 Leptospirosis Of Domestic Animals, Donald B. Hudson

University of Nebraska-Lincoln Extension: Historical Materials

Leptospirosis of domestic animals is a very complex disease. This NebGuide examines its diagnosis, treatment, and prevention.

Introduction

Leptospirosis is an infectious disease of animals and man caused by a spiral-shaped organism (spirochete) of the genus Leptospira. The important serotypes recognized in livestock in the United States include Leptospira pomona, L. canicola, L. icterohaemorrhagiae, L. grippotyphosa and L. hardjo. These organisms have a wide host range, including man. Among domestic animals, swine, cattle, dogs, and horses are most frequently affected. Known wildlife hosts include many of the small rodents, raccoons, foxes, opossums, skunks, deer, and moose.

Specificity Of The Trail Pheromones Of Four Species Of Fire Ants, D. P. Jouvenaz, C. S. Lofgren, D. A. Carlson, W. A. Banks

Entomology Papers from Other Sources

The species specificity of trail pheromones of fire ants, Solenopsis spp., has been studied by Wilson (1962; Anim. Behav. 10: 137-47) and Barlin, Blum, and Brand (1976; J, Insect Physiol. 22: 839-44). Our study, stimulated by taxonomic advances since Wilson's work and conducted concurrently with that of Barlin et al., is presented here to confirm and supplement the latters' observations, and to report some differences in results.

Sex Pheromone Of The Tsetse Fly: Isolation, Identification, And Synthesis Of Contact Aphrodisiacs, D. A. Carlson, P. A. Langley, P. Huyton

Entomology Papers from Other Sources

Sex pheromones isolated from the cuticle of the female tsetse fly, Glossina morsitans morsitans Westwood, release mating behavior in the malefly at ultra- short range or upon contact with baited decoys. Three active components were iden- tified as 15,19-dimethylheptatriacontane, 17,21-dimethylheptatriacontane, and 15,19,23-trimethylheptatriacontane. Chemical and biological comparisons show that the natural and synthetic compounds are identical.

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 …

Biogeographical And Ecological Limits Of New World Passalidae (Coleoptera), Jack C. Schuster

Entomology Papers from Other Sources

In the New World, beetles of the primarily tropical family Passalidae occur in rotting wood from southern Michigan and southern Ontario to northern Argentina, Paraguay, Uruguay, and southern Brazil. They are found in the West Indies, Isla del Coco, and Galapagos Islands. They are not known from the forests of southern Chile or the Pacific North-West, except for the only known fossil of the family from the Oligocene of Oregon. A few species, mostly Proculini, are encountered above 2800 m elevation. The most widely distributed species are those of the tropical lowlands below 1500 m. Most species occur in moist …

Effect Of Energy Source Prior To Parturitian And During Lactation On Tissue Lipid, Liver Glycogen And Plasma Levels Of Some Metabolytes In The Newborn Pig, R. Dean Boyd, B. D. Moser, E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Two experiments were conducted to determine the effect of energy source (carbohydrate or fat), fed to sows prior to parturition and during lactation, on energy storage and some metabolite levels in the neonatal pig which may exert an influence on rate of survival.

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.

Factors Influencing Racing Performance Of The Standard-Bred Pacer, R. L. Hintz, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Generalized least squares solutions were used to estimate effects of post position, track condition, purse within class of race, and breaking stride on time at finish of the Standardbred pacer. A total of 30,181 race records made during the 1972 racing season were analyzed. All effects were found to have a significant influence on time at finish. Differences between effects were generally uniform across age groups. Since post position, track condition, purse within class of race, and breaking stride were found to have a substantial influence on racing performance, these factors should be considered when estimating a horse's racing ability. …

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 …

Direct And Indirect Sire Evaluations For Fat Test And Economic Merit, G. R. Ufford, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Evaluations for milk, fat yield, and fat test for Holstein sires in artificial insemination were calculated from first lactation records of Holstein daughters by best linear unbiased prediction procedures. Indirect evaluations for fat test also were calculated by adding best linear unbiased predictions for milk and fat yield to breed averages for milk and fat yield to calculate test and then subtracting breed average fat test. The indirect evaluation for test had a simple correlation of .99 with fat test from best linear unbiased prediction. Dollar value indexes were calculated from evaluations for milk yield and from evaluations for fat …

Economic Analysis Of Protein Testing For Selection, R. D. Anderson, R. W. Everett, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The expected change in dollar return from incorporating milk, fat, and protein records in a selection index (Index 1) was compared to that from an index utilizing just milk and fat records (Index 2) under pricing systems paying for milk, fat, and protein.

Dollar return 1 was superior to dollar return 2 when there was either no payment for protein or high payment for protein. For sire selection the expected changes in dollar return for the two indices were equal at a price for protein of $.88 per kg whereas for cow selection the returns were equal at a protein …

Estimation Of Genetic Trends From Cow And Sire Evaluations, R. L. Hintz, R. W. Everett, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Milk production records of Ayrshire, Guernsey, Holstein, Jersey, and Brown Swiss in the Northeast were used to estimate trends in transmitting ability of sires and genetic merit of cows. Genetic trends in the transmitting ability of Artificial Insemination sires for the Ayrshire, Guernsey, Holstein, Jersey, and Brown Swiss breeds averaged 23.7, 14.6, 17.9, 18.3, and 34.7 kg per year.

Genetic trends in the AI cow populations averaged 36.1, 25.4, 26.1, 25.0 and 38.1 kg. The genetic trends of cow populations were less than twice the contribution of sires to genetic trends, indicating that estimating genetic trends in cow populations by …

A Bibliography Of Anthropology-Related Serial Publications In The University Of Nebraska Libraries, Kenneth P. Lohrentz, Ann Larson, Linda Mager

Nebraska Anthropologist

This bibliography of anthropological serials in the University of Nebraska Libraries has been undertaken primarily for two reasons. The first follows from the incredibly diverse nature of the discipline itself, for the study of man and his origins has given rise to various methods of inquiry and interdisciplinary overlays. As Sol Tax has pointed out, the study of man appears to have no natural boundaries. It comes as little surprise, therefore, that the bibliography representing the published record of such a varied field of study should itself be extremely diffuse. Add to this natural diffusion the characteristic pattern of dispersed …
