Space Allocation Decisions For Barrows And Gilts, Mike Brumm, Jim Dahlquist Jan 1997

Space Allocation Decisions For Barrows And Gilts, Mike Brumm, Jim Dahlquist

Nebraska Swine Reports

An experiment was conducted to determine if barrow and gilt performance could be modified by varying pen space allocation for each sex and whether performance of barrows given less space per pig could be enhanced with a more nutrient-dense diet. Barrows given 6 ft2 of pen space per pig consumed less feed and grew slower with no effect on lean gain compared to barrows provided 7 ft2 of pen space per pig. Increasing diet nutrient density by feeding the diet sequence recommended for gilts to barrows had no effect on performance for barrows at 6 ft2 per …

Pork Quality Assurance...Dollars And Sense, Angela Baysinger Jan 1997

Pork Quality Assurance...Dollars And Sense, Angela Baysinger

Nebraska Swine Reports

Is there any reason a pork producer would not want to reduce production cost or improve management skills? With the pork industry becoming more consumer driven, should producers take an active role in producing a quality pork product? The Pork Quality Assurance (PQA) Program, developed by the National Pork Producers Council on behalf of the pork industry, is available to help pork producers answer these questions and ensure future success.

Impact Of Feeder And Drinker Designs On Pig Performance, Water Use And Manure Production, Mike Brumm, Jim Dahlquist Jan 1997

Impact Of Feeder And Drinker Designs On Pig Performance, Water Use And Manure Production, Mike Brumm, Jim Dahlquist

Nebraska Swine Reports

Two experiments were conducted to examine the impact of feeder and drinker designs on pig performance, water use and manure volume. In the first experiment, pigs with access to a Crystal Springs® wet/dry feeder grew faster, but had a poorer feed conversion and similar carcass merit as pigs using dry feeders with wall-mounted nipple drinkers. Water use was reduced 25.6% in the combined winter and summer trials and manure volume reduced 28.9% in the summer trial for the wet/dry feeder system versus the dry feeder and wall-mounted nipple drinker system. In the second experiment, there was no difference in pig …

The Effects Of Reducing Dietary Crude Protein Concentration On Odor In Swine Facilities, Claudia Obrock H. Jan 1997

The Effects Of Reducing Dietary Crude Protein Concentration On Odor In Swine Facilities, Claudia Obrock H.

Nebraska Swine Reports

The effect of dietary manipulation on odor emission in a research pig facility was evaluated with 26 finishing gilts (initial weight 161 lb). The two diets were formulated to contain 13% crude protein or 9% crude protein supplemented with crystalline amino acids. Two environmental chambers were used and each housed a group of four or five gilts for 21 days. Relative humidity, temperature and air exchange were maintained throughout the experiment. Samples of feces and air were taken on days 4, 7, 11, 14, 18 and 21 of the experiment. Aerial ammonia and hydrogen sulphide concentrations were measured using detector …

Segregated Early Weaning Of Pigs: Dietary Challenges And Opportunities, Stacy Norin, Duane Reese, Austin Lewis Jan 1997

Segregated Early Weaning Of Pigs: Dietary Challenges And Opportunities, Stacy Norin, Duane Reese, Austin Lewis

Nebraska Swine Reports

Segregated early weaning (SEW) technology is being adopted by many producers in the pork industry. With the implementation of this technology come many challenges and opportunities to exploit the lean-growth potential and health status of the SEW pig. This review provides insight into some of the reasons for these challenges and discusses some possible ways of utilizing the unique characteristics of the SEW pig to reduce production costs.

Effect Of Early Weaning On Sow Reproductive Performance — A Review, Donald G. Levis Jan 1997

Effect Of Early Weaning On Sow Reproductive Performance — A Review, Donald G. Levis

Nebraska Swine Reports

A review of literature was conducted to evaluate the effects of lactation length on reproductive performance of sows. As lactation length decreases there is an increase in the weaning-to-estrus interval, a decrease in farrowing rate, a decrease in subsequent litter size and an increase in pigs weaned per sow per year. Because of herd-to-herd differences in the influence of lactation length on reproductive performance, it is advised that each farm conduct a preliminary study to evaluate the effect of the considered lactation length before implementing the “new” weaning age of piglets.

Purple Sulfur Bacteria In Anaerobic Treatment Lagoons, Richard K. Koelsch, Tong Tong Chen, Dennis D. Schulte Jan 1997

Purple Sulfur Bacteria In Anaerobic Treatment Lagoons, Richard K. Koelsch, Tong Tong Chen, Dennis D. Schulte

Nebraska Swine Reports

Purple or pink colored lagoons, indicating the presence of purple sulfur bacteria, are less likely to be considered an odor nuisance than a more typical non-purple lagoon. The design and management factors that encourage the growth of purple sulfur bacteria are poorly understood. A study of eight purple and non-purple lagoons was initiated during the spring and summer of 1996. The intent of this effort was to identify critical factors that would allow purple lagoons to become a more predictable odor control alternative. A preliminary comparison of design and management factors assumed to be critical suggests more similarities between these …

Growth Performance And Digestive And Metabolic Responses Of Finishing Gilts Penned Individually Or In Groups, Sergio Gómez-Rosales, Phillip S. Miller, Austin Lewis Jan 1997

Growth Performance And Digestive And Metabolic Responses Of Finishing Gilts Penned Individually Or In Groups, Sergio Gómez-Rosales, Phillip S. Miller, Austin Lewis

Nebraska Swine Reports

An experiment was conducted using one or four finishing gilts/pen to identify factors related to the lower performance of pigs penned in groups. Feed intake, daily gain and final weight were greater in pigs penned individually. There was a trend for greater loin weight and primal cut percentage for pigs penned individually. Apparent digestibilities of dry matter, crude protein and gross energy and the plasma concentrations of urea, glucose and nonesterified fatty acids were similar for both individually and group-penned pigs. These results suggest the lower performance of group-penned pigs is related neither to changes in digestive processes nor plasma …

Explanation Of Statistics Used In This Report Jan 1997

Explanation Of Statistics Used In This Report

Nebraska Swine Reports

Pigs treated alike vary in performance due to their different genetic makeup and to environmental effects we cannot completely control. When a group of pigs is randomly allotted to treatments, it is nearly impossible to get an “equal” group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

Retention Of Selected Nutrients In Grilled Boneless Pork Chops, Judy A. Driskell, Fayrene Hamouz, Sharon Davis, David Giraud, Jidong Sun Jan 1997

Retention Of Selected Nutrients In Grilled Boneless Pork Chops, Judy A. Driskell, Fayrene Hamouz, Sharon Davis, David Giraud, Jidong Sun

Nebraska Swine Reports

Fresh pork Canadian Backs, cut into boneless pork chops, were cooked to 160°F internal temperature by grilling at one of the following temperatures: 200, 250, 300, 350, or 400°F. Significantly longer cooking times were observed for chops grilled at 200°F than for those grilled at the higher temperatures. The yields, as well as the moisture and crude fat content of the chops in the different treatments, were similar. Retention values for selenium were similar for all treatment groups. Chops grilled at 400°F had significantly lower retention values for vitamin E and thiamin and a tendency for lower retention values for …

Addition Of Fat To Diets Of Lactating Sows: Ii. Effects On Energy Mobilization And Hormone-Sensitive Lipase Activity, Scott Tilton, Austin Lewis, Phillip S. Miller, Paul Ermer Jan 1997

Addition Of Fat To Diets Of Lactating Sows: Ii. Effects On Energy Mobilization And Hormone-Sensitive Lipase Activity, Scott Tilton, Austin Lewis, Phillip S. Miller, Paul Ermer

Nebraska Swine Reports

The effect of dietary fat intake on the ability of the lactating sow to mobilize energy from adipose tissue fat was examined. Sows had ad libitum access to diets formulated to contained 1% lysine and either zero or 10% tallow. Data from two epinephrine challenges indicated sows fed tallow tended to have higher baseline concentrations of nonesterified fatty acids (NEFA) and lower stimulated release of NEFA in response to epinephrine than did control sows. Because baseline glycerol values did not differ between treatments, we interpreted this to suggest control sows tended to re-esterify (recycle) a greater portion of the fatty …

Dietary Fiber In Sow Gestation Diets — A Review, Duane Reese Jan 1997

Dietary Fiber In Sow Gestation Diets — A Review, Duane Reese

Nebraska Swine Reports

Gestation sows are well suited to utilize high-fiber, low-density diets. They utilize fiber better than growing pigs and during gestation have a high feed intake capacity relative to their energy requirement. When research results from several studies were pooled and weighted according to the number of litters produced, sows fed additional fiber during gestation farrowed and weaned more pigs/litter than sows fed control diets. Feeding fiber during gestation also improved lactation feed intake, but reduced sow weight gain during pregnancy and pig birth weight. Sows fed fibrous diets also exhibit less stereotypic behavior (i.e., bar-biting), which may be an indication …

Pattern And Process In Biological Invasion, Diane L. Larson Jan 1997

Pattern And Process In Biological Invasion, Diane L. Larson

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

A cohesive theory of biological invasion has been frustratingly elusive. If nothing else, Mark Williamson's book, Biological Invasions, has convinced me of the futility in looking for broad patterns among the widely disparate creatures that have invaded almost every conceivable environment.

Assessing The "Contract Failure" Explanation For Nonprofit Organizations And Their Tax-Exempt Status, Daniel N. Shaviro Jan 1997

Assessing The "Contract Failure" Explanation For Nonprofit Organizations And Their Tax-Exempt Status, Daniel N. Shaviro

Faculty Articles

The best known account in recent legal or economic literature of why certain organizations use the nonprofit form, and when or why they ought to be tax-exempt, comes from Henry Hansmann. Hansmann argues that the nonprofit form prevails where it does because it responds efficiently to problems of "contract failure" where behavior is hard to monitor. For example, I might not trust a for-profit company to use my donation to provide famine relief in a foreign country or to render "complex personal services" such as nursing care, given the difficulty of observing performance directly. The nonprofit structure is supposed to …

Takings, Exclusivity And Speech: The Legacy Of Pruneyard V. Robins, Richard A. Epstein Jan 1997

Takings, Exclusivity And Speech: The Legacy Of Pruneyard V. Robins, Richard A. Epstein

Faculty Articles

In the first section, I contrast two approaches to the law of takings, one that treats takings disputes as derivative of or dependent on private law conceptions of property, and the second which does not. I argue that only the first maintains the integrity of constitutional doctrine, while the second, in common use today, affords insufficient protection against the expansion of state power. Second, I examine the status of the right to exclude as part of the basic bundle of property rights, chiefly in connection with Kaiser Aetna v United States, which announced the premier status of the right to …
