This fact sheet provides insight and answers to aspiring pig farmers so that they can make better-informed decisions before purchasing their pigs.

Optimization Of Conditions For Heat Pretreatment And Enzymatic Predigestion Of Ddgs For Pigs, Kevin Jerez-Bogota

Electronic Theses and Dissertations

The high fiber content of corn dried distillers’ grains with solubles (DDGS) can limit its utilization in swine diets. Pretreatment with heat and enzymatic predigestion of whole stillage (WS; slurry material that is dried into DDGS) can alleviate negative effects of dietary fiber and can improve digestive and fermentation characteristics of the feedstuff. However, optimal time and temperature of the heat pretreatment of WS, and best enzymes for predigestion of WS have not been identified. Experiments were conducted to identify optimal conditions for heat pretreatment and multienzyme predigestion of WS for pigs. First experiment was conducted to identify optimal temperature …

Meat For Missoula: Educating Our Youth On Sustainable Meat Production Practices, Amelia R G Liberatore

Undergraduate Theses, Professional Papers, and Capstone Artifacts

In autumn 2016, a controversy arose when a student group, Advocates for Animals, took up a campaign against three meat pigs at the PEAS Farm due to strong views about animal consumption. Pigs serve as a central piece of food source education to hundreds of Missoula children who visit the farm every year. Unfortunately, the controversy overshadowed the educational purpose of exposing children to sustainable meat production practices. Moreover, access to the PEAS Farm and good food education is not available to all local children. I wondered whether education was accessible elsewhere. Unfortunately, child-appropriate, culturally relevant food literature is scarce. …

Nf01-454 Information About Foot And Mouth Disease For Nebraska Residents, David R. Smith

University of Nebraska-Lincoln Extension: Historical Materials

Foot and mouth disease (FMD) is an extremely contagious viral disease of cloven-hooved animals such as cattle, pigs, sheep, and deer. The disease is not commonly fatal, but causes extreme production losses in affected herds. Clinical signs of the disease include lameness, excessive salivation, reluctance to eat, abortion and blister-like erosions on the mouth and feet. Affected animals are debilitated and may not recover to their original production levels. The disease has long been recognized as one of the most economically devastating diseases of livestock.

Ec97-275 Effect Of Lactation Length On Sow Reproductive Performance, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

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, each farm should conduct a preliminary study to evaluate the effect of the lactation length being considered before implementing the “new” weaning age of piglets.

Ec97-276 Management Strategies For Pen-Mating Female Pigs, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

The master control switch of a pork production enterprise is weaning day. Pork production managers have little or no control concerning when a weaned female will cycle or how long she will be in estrus after weaning. When females are pen-mated, the producer needs to use management procedures to prevent an excessive number of estrous females from expressing the standing response at the same time, try to manage estrous females so that they are bred at the proper time, try to manage boars so they maintain an adequate level of fertility, evaluate boars for level of sexual behavior before and …

Ec95-745 Managing Livestock Odors: Principles, Assessment And Planning, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

Odors associated with livestock manure represent a growing challenge for livestock producers. Livestock production trends such as more animals per farm and expanded reliance upon manure storage have added to the odor muisance. Implementing other environmentally friendly practices such as manure nutrient management and maintenance of surface crop residues for soil conservation also have resulted in additional odor challenges.

Odors originating from livestock wastes are a common source of irritation between producers and neighbors. Confrontations may lead to more stringent local zoning regulations, greater scrutiny of other farm environmental issues, and litigation.

This publication summarizes the underlying causes of livestock …

University of Nebraska-Lincoln Extension: Historical Materials

What is porcine somatotropin (pST)?

Porcine somatotropin, abbreviated as pST, is a growth hormone naturally produced in pigs. The word "porcine" refers to pigs, and the word "somatotropin" means body growth and refers to the name of the hormones.

This research publication discusses what porcine somatotropin is, how scientists developed pST, how the protein nature affects its use, what research shows, is pST safe and will consumers accept it, and what is pST's future.

G91-1049 Controlling Internal Parasites In Swine, B.E. Straw

University of Nebraska-Lincoln Extension: Historical Materials

This publication addresses the identification, prevention and control of internal parasites in swine and lists characteristics of principle dewormers.

Whether pigs are raised in confinement or on pasture, controlling internal parasites is essential to the overall herd health program. Recent studies by Tom Kennedy of A.E.F. Research, Inc, Waunakee, WI, have shown that worm infestation is prevalent on both a farm and individual pig basis. Of the farms examined, 91 percent raised pigs on concrete, wire or slotted floors, but more than 90 percent of all farms were infested with one or more kinds of worms.

G90-994 Full-Fat Soybeans For Pigs (Revised July 1992), Duane Reese

University of Nebraska-Lincoln Extension: Historical Materials

Several factors should be considered when feeding full-fat soybeans to swine, including nutrient composition, performance, economic considerations and diet formulations.

Soybean meal is the most common supplemental protein source used in pig diets. It is widely available, and often produces the most economical gains when compared with other protein sources. For various reasons, feeding full-fat soybeans to pigs, instead of soybean meal, may be an attractive alternative.

G89-926 Swine Reproductive Problems: Infectious Causes, Alex Hogg, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes causes, clinical signs, control, prevention and treatment of swine reproductive problems due to infectious diseases. The reproductive potential for the ideal sow has been calculated as 31.2 pigs weaned per year. The United States average is 14 pigs per sow per year--less than one-half the reproductive potential of the ideal sow. A major part of this low reproductive efficiency is due to either infectious or non-infectious causes. The infectious causes of swine reproductive problems are addressed here.

G86-821 Weaned Pig Management And Nutrition (Revised August 1992), Duane Reese, Mike Brumm

University of Nebraska-Lincoln Extension: Historical Materials

Temperature, space, health considerations, dietary nutrient allowances, feeding management and more are covered here. The weaning age of pigs farrowed in Nebraska is variable. While the average age at weaning is about four weeks, the range is from two to eight weeks. However, industry surveys indicate that more than 50 percent of the pigs in the United States are weaned at 28 days of age or earlier, with the majority weaned between three and four weeks of age. This trend towards earlier weaning is expected to continue with advances in management, housing, health and nutrition. Earlier weaning (under 28 days) …

G85-748 Prevention And Control Of Swine Dysentery, Gerald E. Duhamel, Alex Hogg, Barbara E. Straw

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the causes and symptoms of swine dysentery and offers management recommendations and treatment procedures for its prevention and control.

Swine dysentery is a highly contagious disease of growing and finishing pigs. First described in Indiana in 1921, it has been called black scours, bloody scours, and vibrionic dysentery.

Swine dysentery causes important financial losses because of reduced feed efficiency and lower weight gain, costs of medication and additional animal care, and death. Substantial costs may result from loss of sales of breeding stock, or depopulation when necessary. Serpula (Treponema) hyodysenteriae, a spiral bacterium, is the cause …
