Influence Of Encapsulation Of Supplemental Amino Acids On Their Utilization In Broilers, Ethan A. Collins May 2021

Influence Of Encapsulation Of Supplemental Amino Acids On Their Utilization In Broilers, Ethan A. Collins

Poultry Science Undergraduate Honors Theses

This study was developed to assess whether microencapsulation of amino acids (AA) improves their absorption to increase broiler growth performance and reduce nitrogen excretion compared to standard feed-grade AA. Five hundred and sixty Ross 708 male broilers were randomly distributed to 70 battery cages and reared for 21 days. Reported data is grouped into periods: 0-7 days, 0-14 days, and 0-21 days. A total of 5 treatment diets were fed: an industry-based control and 4 diets with decreased levels of methionine, lysine, and threonine in either encapsulated or free forms, with or without a botanical feed additive. Encapsulated AA increased …


Evaluation Of Selected Bacillus Direct-Fed Microbial Candidates In Reduced Energy Diets On Live Performance, Carcass Characteristics, And Foot Pad Dermatitis, Kyle Teague Dec 2020

Evaluation Of Selected Bacillus Direct-Fed Microbial Candidates In Reduced Energy Diets On Live Performance, Carcass Characteristics, And Foot Pad Dermatitis, Kyle Teague

Graduate Theses and Dissertations

Bacillus spp. are ubiquitous, Gram-positive, spore forming bacteria that are commonly recovered from the environment and gastrointestinal tract (GIT) of poultry. These spores are capable of withstanding harsh condition such as feed pelletization, which facilitates inclusion in poultry feeds. Once ingested by the bird, spores germinate into metabolically active vegetative cells which can produce extracellular enzymes which can hydrolyze otherwise indigestible components of the feed. Soybean meal (SBM) is the gold standard vegetable protein source for non-ruminant animals worldwide and is included in practically all poultry diets in the United States at levels ranging from 10 to more than 30%. …


Pigs And Poultry, Nicole Burton Jan 2020

Pigs And Poultry, Nicole Burton

Sustainability Education Resources

This course provides students with a farmer’s perspective on the management, production and marketing of poultry and pigs on a small farm. This course will address the advantages of having pigs and poultry and will review basic care, processing options, regulations, marketing and finances. The course will be structured around lectures, farm visits, guest lectures and acquiring hands on skills. We will explore different alternative farming systems that utilize animals to enhance their production. At the end of this course, students will be able to utilize pigs and poultry as an integral part of their small farm plan.


Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann Aug 2019

Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann

Graduate Theses and Dissertations

Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low …


Effect Of Cooking Method On Meat Texture In Normal And Woody Broiler Breast Fillets Using Instrumental Analysis And Descriptive Sensory Analysis, Lynda D. Combs Dec 2018

Effect Of Cooking Method On Meat Texture In Normal And Woody Broiler Breast Fillets Using Instrumental Analysis And Descriptive Sensory Analysis, Lynda D. Combs

Graduate Theses and Dissertations

Over the past few decades, broiler breast meat has changed in terms of meat quality. Meat quality has deteriorated with the rise in the occurrence of muscle myopathies. Conditions such as woody breast, which is described as pale and bulging areas of distinct hardness, compromise both the textural and technological traits that have been associated with breast meat. The Meullenet-Owens Razor Shear (MORS) method is a common method for indirectly assessing poultry meat tenderness. A blunt version of the MORS (BMORS) has been shown to be a more sensitive method at higher degrees of toughness. A slightly larger stainless steel …


Efficacy Of Natural Compounds With Novel Carrier Systems For Controlling Campylobacter Jejuni In Post-Harvest Poultry, Sandip Shrestha Dec 2018

Efficacy Of Natural Compounds With Novel Carrier Systems For Controlling Campylobacter Jejuni In Post-Harvest Poultry, Sandip Shrestha

Graduate Theses and Dissertations

Campylobacter jejuni, a leading cause of bacterial gastroenteritis worldwide, is strongly associated with the consumption and/or mishandling of raw contaminated poultry products. Thus, interventions aiming to reduce C. jejuni counts on poultry products could greatly reduce the incidence of human campylobacteriosis. In the first study, the efficacy of a generally recongnized as safe (GRAS) compound, carvacrol (CR; derived from oregano oil), as an antimicrobial wash treatment to reduce C. jejuni on chicken skin was evaluated. Three delivery systems of CR: suspension, emulsion and nanoemulsion were used. C. jejuni counts were reduced up to 4 log10 cfu/sample by 2% dose of …


Characterization Of Broiler Lines Divergently Selected For Breast Muscle Color, Sara Katherine Orlowski Aug 2016

Characterization Of Broiler Lines Divergently Selected For Breast Muscle Color, Sara Katherine Orlowski

Graduate Theses and Dissertations

An increase in the consumption of poultry has generated an increase in demand for higher yielding broilers. This has led to an increase in atypical meat and issues with appearance. Color is a direct result of a pH decline as meat goes through rigor mortis with meat generally becoming lighter. If the pH declines too rapidly or too slowly, meat quality can suffer. Physical properties of meat can be altered by pH. A fast pH decline results in pale meat with decreased tenderness. A slow pH decline can result in darker meat with a reduced shelf-life. With a known relationship …

Bulletin 2220: Best Management Practices For Small Scale Poultry Producers In Maine, Richard Brzozowski, Donna R. Coffin, Michael Darre

Cooperative Extension - Agriculture

Written for small-scale poultry producers. University specialists, Extension educators, and agriculture service providers from New England and New York developed this list of Best Management Practices to assist small-scale poultry growers to provide the best of care for their birds, minimize losses due to disease and predation, as well as minimizing the impact on the environment while assuring a high quality, wholesome product for their family and customers.
