Notes On Some Mammals From Jalisco, Mexico, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The varied topography and climate of the Mexican state of Jalisco have resulted in a diverse mammalian fauna, no comprehensive account of which has been published. Significant collections of mammals from Jalisco were obtained for the Museum of Natural History, the University of Kansas, between 1949 and 1969 by field parties and individual field representatives, most notably J. R. Alcorn, R. W. Dickerman, and especially P. L. Clifton. Some of the specimens thus obtained have been recorded in systematic accounts of individual taxa or in reports on selected taxonomic groups (see for example, Choate, 1970; Genoways, 1972; Genoways and Jones, …

Animal Damage Control In South Dakota, V. Van Ballenberghe

Great Plains Wildlife Damage Control Workshop Proceedings

South Dakota, like virtually all other states, is subject to economic losses from wildlife depredations. We have been in the government sponsored, animal damage control business perhaps longer than some states - our history dates back to the time of Three-toes and the Custer Wolf. In 1973 we are still in that business, perhaps more intensively than ever before, and we regard animal damage control as one of the most pervasive and difficult to solve wildlife problems facing us.

The Missouri River bisects South Dakota into approximately equal "East River" and "West River" land areas. These differ ecologically, and to …

The Presuppositions Of Name-Calling In English, Robert S. Haller

Department of English: Faculty Publications

I have offered evidence that name-calling is a linguistic act which correlates the assumption of a status-relation between speaker and addressee with the use of terms marked (+abusive). To call someone a bastard, for.this reason, is not understood as the attempt to categorize him according to some term whose meaning, in the ordinary sense, is a list of lexical features. Rather it is the attempt to categorize him as without status in relation to the speaker himself, in defiance of his expectations, and because he has himself deserved it by himself invoking such a right over the speaker. This understanding …

Kansas Predator Damage Control Program, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

The Extension Division is the off-campus arm of Kansas State University~ a land grant university functioning through 105 county Extension offices involving over 265 county Extension workers that are backed up by some 175 state and area subject matter specialists. Kansas is an agricultural state. The production of livestock in Kansas is an important industry to our state and nation.

Our predator damage control program is an educational effort directed at the goal of reducing livestock losses where possible on individual farms and ranches, in Kansas. Our program has been in existence since 1954. A very important aspect of our …

Coyote Denning As A Method Of Damage Control, Walden C. Lemm

Great Plains Wildlife Damage Control Workshop Proceedings

The coyote denning operation is a useful method in coyote control, both to control populations and to eliminate problem animals, but a thorough knowledge of coyote behavior prior to and during the denning season is essential for productive results.

Coyotes do not dig their own dens, but enlarge existing holes dug by other animals, often those dug by badgers. Coyote den holes are not difficult to distinguish from holes dug by smaller animals. Being long-legged animals, their den entrances are elongated vertically instead of being round like those of badgers and other short-legged animals.

An Assessment Of The Coyote Problem In The Great Plains States, Dale A. Wade

Great Plains Wildlife Damage Control Workshop Proceedings

It has now been 21 months since President Nixon's Executive Order #11643 was issued and there has been a complete annual reproductive cycle in the coyote population of the western states without any major influence by chemical controls. The use of mechanical controls, including non-lethal methods, and greater emphasis on removing only specific offending animals has been advocated during this time as a solution where coyotes prey on domestic animals. With this brief look back, what have been the results?

We do not have absolute data on coyote numbers and livestock depredations resulting from this change in coyote management programs. …

G73-15 Handling Feed Moisture In Ration Formulation And Inventory Control (Revised December 1983), Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Nutritional quality control begins with knowing and adjusting for variation in the moisture content of feed ingredients. Moisture variations in feeds are almost always of more importance than variations in protein, mineral, and energy. Inventory control is affected by moisture content of feeds. Some feeds on hand are constantly changing in moisture content, and these changes frequently lead to financial losses when a price adjustment is not made for moisture losses.

Chronic Effect Of Low Ph On Fathead Minnow Survival, Growth And Reproduction, Donald I. Mount

United States Environmental Protection Agency: Publications

Fathead minnows (Pimephales promelas Rafinesque) were continuously exposed to reduced pH levels of 4.5, 5.2, 5.9, 6.6 and 7.5 (control) during a 13-month, one-generation test. Survival was not affected, even at the lowest pH tested. Fish behavior was abnormal, and fish were deformed at pH 4.5 and 5.2. Egg production and egg hatchability were reduced at pH 5.9 and lower, and all eggs were abnormal. A pH of 6.6 was marginal for vital life functions, but safe for continuous exposure. Free carbon dioxide, liberated by the addition of sulfuric acid to reduce the pH, may have had an unknown …

Ec73-1907 Internal Parasites Of Cattle, D. L. Ferguson

University of Nebraska-Lincoln Extension: Historical Materials

Extension Circular 73-1907 is about internal parasites in cows and how they affect cattle production.

Internal parasites continue to be one of the major problems confronting cattle producers. In 1965, the United States Department of Agriculture estimated that internal parasites in cattle caused an average annual loss of $161,678,000. The internal parasites responsible for the annual loss are listed below.

Anaplasmosis. .$ 36,001,000

Coccidiosis . . . .14,569,000

Worm Parasites .100,046,000

Liver Flukes . . . 3,022,000

Trichomoniasis .. 8,040,000

In cattle the effects of internal parasites will be well camouflaged. However, additional feed will be required to reach market …

Preliminary Interpretations Of Coyote Population Mechanics With Some Management Implications, Frederick F. Knowlton

Great Plains Wildlife Damage Control Workshop Proceedings

The need for control of coyote (Canis latrans) depredations and a simultaneous demand for recognition of the aesthetic and ecologic values of the species create a conflict in resource utilization that should be resolved through more intensive management. A coyote population model is proposed from current estimates of density, reproduction, population structure, and mobility. Densities of 0.5 to 1.0 coyote per square mile are frequently suggested, with occasional estimates of 4.0 or more per square mile. Reproductive rates fluctuate as functions of the proportion of females that ovulate, the average number of ova shed, and in utero viabilities. …

Parameters Of Growth Of Holstein-Friesian Bulls, L. L. Calo, R. E. Mcdowell, L. Dale Van Vleck, P. D. Miller

Department of Animal Science: Faculty Publications

Growth records of 504 pedigree selected Holstein-Friesian bulls by 120 sires collected for progeny testing at the American Breeders Service, Inc., DeForest, Wisconsin from 1964 to 1971, were studied to determine the shape of the growth curve, relationships among body weights and growth rates at various ages and to estimate heritability of growth. Body weight and average/daily gain were consistently higher than the previous growth standards for Holstein-Friesian bulls. Bulls weighed about 480 kg at 15 months, which was 46% of average mature weight. Average daily gain ranged from 1.3 to 0.8 kg between 6 and 18 months of age. …

Effect Of Amino Acids On Non-Protein Nitrogen Utilization By G-F Swine, P. D. Platter, E. R. Peo, Jr., P. E. Vipperman, P. J. Cunningham

Reproductive Efficiency In Aged Female Rabbits Given Supplemental Progesterone And Oestradiol, Larry L. Larson, C. H. Spilman, H. O. Dunn, R. H. Foote

Department of Animal Science: Faculty Publications

The reproductive efficiency of twenty-eight aged does, 49 to 72 months old, was compared with that of eighteen young does, 6 to 13 months old. Fertilization rate and development in vitro of fertilized ova from rabbits induced to superovulate were not influenced by the doe's age. Ovulation rates following natural mating were only slightly reduced with age. However, the number of embryos per doe was much greater in young than in old does at 12 and 24 days post coitum. All young does had viable embryos, whereas the percentages of aged does with detectable implantation sites and viable embryos were …

Subjective Evaluation Of Teat Canal Anatomy, R. D. Appleman

Department of Animal Science: Faculty Publications

Since radiographic techniques have shown that streak canals with larger diameters tend to milk-out faster and are more susceptible to new intramammary infections, a practical visual test was sought to provide easier determination of cows with either extremely narrow (slow milking) or extra wide (susceptible to new infections) streak canals.

A subjective teat classification scheme was developed to describe five different teat-end shapes in 159 Holstein and Brown Swiss cows in the University of Nebraska dairy herd. Approximately one-fourth of the cattle had pointed or round teat ends, one-half had fiat or near flat, and one-fourth were either disk or …

Evaluation Of Purebreds And Two-Breed Crosses In Swine: Feedlot Performance And Carcass Merit , R. K. Johnson, I. T. Omtvedt, L. E. Walters

Department of Animal Science: Faculty Publications

Feedlot performance of 941 barrows and gilts and carcass traits of 190 barrows of purebreds and crossbreds of the Duroc, Hampshire and Yorkshire breeds were evaluated for differences between purebreds and reciprocal crosses and for heterosis. Purebred and crossbred litters were farrowed contemporaneously at the Ft. Reno Experiment Station in the 1971 spring and fall farrowing seasons.

Rather distinct differences between the pure breeds were evident for most traits. In general, Durocs gained weight more rapidly than Hampshires and Yorkshires while Yorkshires were the most efficient pure breed. Hampshire barrows had less backfat, more loin eye area and more total …

G73-4 Bagworms (Revised June 1987), Frederick P. Baxendale

University of Nebraska-Lincoln Extension: Historical Materials

Bagworms can damage juniper, arborvitae, pine, and spruce. Description, life history, and control are discussed in this publication.

The bagworm is native to the United States and is found in eastern Nebraska. Bagworms feed on many species of trees and shrubs, but are most common on junipers. They are rarely a serious problem on deciduous trees, except when larvae move away from evergreens.

A Brief History Of Extension Predator Control In Missouri, Dan F. Dickneite

Great Plains Wildlife Damage Control Workshop Proceedings

Missouri, like many of its neighbors, has long had to content with complaints of damage caused by predatory wildlife. Unlike some other states, however, in Missouri the control, management, restoration, etc. of all bird, fish and game and other wildlife resources of the state is vested in a Conservation Commission to an exclusive degree. Because of this Constitutional mandate, the Conservation Department in Missouri has been the agency primarily responsible for assisting farmers and ranchers with their various wild animal damage control problems. Poisons and explosive or chemical devices are not legal. This legal prohibition not withstanding, Missouri's relatively dense …
