Evaluation Of Supplementing Whole Cottonseed Within Feedlot Rations During The Stockerphase Of Production With The Goal Of Increasing Average Daily Gain, Emily Lauren Cook

Masters Theses & Specialist Projects

Beef calves are weaned at 6-months of age and enter the stocker phase of beef production. Stocker producers have the primary goal of adding weight inexpensively to increase profit on weaned calves. Whole cottonseed is an inexpensive feed ingredient that is popularly top-dressed within dairy and finishing beef diets and is high in protein and energy. During three periods lasting 50-days (fall 2019, fall 2020, and spring 2020), freshly weaned calves were placed on a finishing ration with the goal of increasing average daily gain. Base rations were calculated at 25% tall fescue hay, 23% corn, and 52% distillers’ solubles ...

Faculty Papers and Publications in Animal Science

Background: Infectious Bovine Keratoconjunctivitis (IBK), commonly known as pinkeye, is one of the most significant diseases of beef cattle. As such, IBK costs the US beef industry at least 150 million annually. However, strategies to prevent IBK are limited, with most cases resulting in treatment with antibiotics once the disease has developed. Longitudinal studies evaluating establishment of the ocular microbiota may identify critical risk periods for IBK outbreaks or changes in the microbiota that may predispose animals to IBK.

Results: In an attempt to characterize the establishment and colonization patterns of the bovine ocular microbiota, we conducted a longitudinal study ...

Although pork producers typically aim to optimize growth rates, occasionally it is necessary to slow growth, such as when harvest facility capacity is limited. In finishing pigs, numerous dietary strategies can be used to slow growth so pigs are at optimal slaughter body weights when harvest facility capacity and/or access is restored. However, the impact of these diets on pork carcass quality is largely unknown. Thus, this study aimed to evaluate the efficacy of dietary strategies to slow growth in late finishing pigs and evaluate their effects on carcass composition and pork quality. Mixed-sex pigs (n = 897; 125 ± 2 ...


Organic Production Of Livestock And Livestock Products In Nebraska, Elliott James Dennis 2020 University of Nebraska - Lincoln

Organic Production Of Livestock And Livestock Products In Nebraska, Elliott James Dennis

Extension Farm and Ranch Management

First paragraph:

USDA “Certified Organic” is a form of production that has received considerable public attention in the last 10 years, particularly among small, beginning and/or minority farmers. Spiking retail prices for red meat and poultry have seemingly accelerated consumer’s interest in organic locally produced products. Consumers demonstrate their desire for these products by paying premiums when purchasing meat products. Producers receive premiums by either directly marketing live animals to consumers that are custom harvested or marketing animals to meat wholesalers. The primary difference is the way premiums are captured. Producers doing custom harvesting capture the full premium ...


Characterization Of Growth Patterns And Meat Quality Characteristics Of Four Commercial Broiler Strains In Small Bird And Large Bird Programs In The United States, Clay Johnny Maynard 2020 University of Arkansas, Fayetteville

Characterization Of Growth Patterns And Meat Quality Characteristics Of Four Commercial Broiler Strains In Small Bird And Large Bird Programs In The United States, Clay Johnny Maynard

Theses and Dissertations

Through current trends in animal protein consumption, the United States poultry industry has seen a drastic rise in production and popularity. Over the last few decades, poultry meat has surpassed both beef and pork production to become the most widely consumed animal protein. This rise may be accredited to an increased transition to more health-conscious consumers. As more consumers purchase poultry as a lean source of protein, the need for a superior quality product is of great interest to poultry integrators.

Relationships between commercial broiler lines have been well documented in previous years, but constant and intensive genetic selection in ...

The Use Of Inorganic And Organic Acids As Short Duration Antimicrobial Dips On Mitigating Pathogens Present On Commercial Chicken During Peri-Harvest, Dana Kristen Dittoe

Theses and Dissertations

With poultry being the most consumed meat in the United States, poultry processors must provide consumers with safe, wholesome products. As a consequence, poultry processors are faced with the challenge of reducing the presence of foodborne pathogens such as Salmonella spp. and Campylobacter jejuni among raw poultry products. Though multi-hurdle approaches using antimicrobials are placed throughout processing to reduce these pathogens, Salmonella and C. jejuni still persist among raw poultry. Thus, it was the objective of the current dissertation to investigate various antimicrobials, organic and inorganic acids, as short duration dips and sprays as means to reduce common pathogens (Salmonella ...

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

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 ...

Faculty Papers and Publications in Animal Science

Background: Genetic testing for pedigree accuracy is critical for managing genetic diversity in North American (NA) yak (Bos grunniens ), a population expanded mostly from imported zoological park specimens. DNA testing also enhances species conservation by identifying recent B. taurus F1 hybrid ancestors (within three generations). Biallelic single nucleotide polymorphisms (SNPs) can accomplish either task, but increases the marker count and costs necessary to achieve both. Our aim was to identify novel, multifunctional, triallelic yak SNPs (tySNPs), with each having two alleles for yak parentage testing, and a third allele for identifying recent cattle introgression.

Methods: Genome sequences were aligned to ...

Faculty Papers and Publications in Animal Science

In spring 2020, six Hereford calves presented with congenital facial deformities attributed to a condition we termed mandibulofacial dysostosis (MD). Affected calves shared hallmark features of a variably shortened and/or asymmetric lower mandible and bilateral skin tags present 2–10 cm caudal to the commissure of the lips. Pedigree analysis revealed a single common ancestor shared by the sire and dam of each affected calf. Whole-genome sequencing (WGS) of 20 animals led to the discovery of a variant (Chr26 g. 14404993T>C) in Exon 3 of CYP26C1 associated with MD. This missense mutation (p.L188P), is located in an ...

Losses due to infectious diseases are one of the main factors affecting productivity in the swine industry, motivating the investigation of disease resilience-related traits for genetic selection. However, these traits are not expected to be expressed in the nucleus herds, where selection is performed. One alternative is to use information from the commercial level to identify and select nucleus animals genetically superior for coping with pathogen challenges. In this study, we analyzed the genetic basis of antibody (Ab) response to common infectious pathogens in health-challenged commercial swine herds as potential indicator traits for disease resilience, including Ab response to influenza ...

Uncertainties Abound In Nebraska Livestock Market Forecasts, Elliott James Dennis 2020 University of Nebraska - Lincoln

Uncertainties Abound In Nebraska Livestock Market Forecasts, Elliott James Dennis

Extension Farm and Ranch Management

About one of the only things certain about forecasts this year has been the great deal of uncertainty. Numerous “novel” situations have confronted the industry making it difficult to estimate price magnitudes rather than just price direction. Clustered plant closures, government quarantine restrictions, and increasing at home phone consumption are just a few of the major issues the beef industry has had to tackle in the last six to eight months. Some things have returned to “normal” such as packing plant capacity and food service demand. Others are still in ongoing recovery.

Who knows what “normal” or “standard operating procedure ...
