The Effects of Different De-feathering Methods on Salmonella Attachment to Chicken Skin and Antimicrobial Efficacy
(2016-07-22)
Chickens usually arrive at processing facilities with high populations of microorganisms. Salmonella is a major concern in poultry and poultry products in regards to food safety. During the initial steps of slaughter (i.e., ...
The Effects of Electrostatic Polarization Ultra-Violet Light Filters on the Bioaerosols of a Commercial Broiler Processing Plant Hang Room
(2009-12-17)
Poultry processing hang rooms are recognized as potentially one of the dirtiest areas of a first processing plant. Little research focuses on the amount of debris in the air of a hang room and its potential effects on cross ...
Effects of Extended Deboning Times on the Breast Meat Quality of Fast-Growing Big Broilers
(2018-04-26)
Big broilers can be affected with wooden breast myopathy leading to quality issues such
as tough meat texture. Toughness is possibly enhanced due to deboning broilers at 2-3 h post
mortem with incomplete resolution of ...
Effects of feeding reduced crude protein diets while maintaining essential amino acids and total glycine + serine concentrations on growth performance, nitrogen excretion, plasma uric acid concentrations, and carcass characteristics of broilers
(2016-10-04)
An excessive reduction of crude protein (CP) content in broiler diets has been resulting in poor growth performance. This may be due to sub-optimum concentrations of Val, Ile, Arg, and Trp. Additionally, total Gly + Ser ...
The Effects of Feeding Reduced-oil DDGS to Broilers when Challenged with C. perfringens and Eimeria spp. on Necrotic Enteritis and Intestinal Microbiome.
(2017-11-17)
Clostridium perfringens-associated necrotic enteritis (NE) costs the international poultry industry an estimated $6 billion annually. Traditionally, the incidence of NE has been controlled by the use of antibiotic growth ...
Effects of high dietary copper concentration on growth performance, processing characteristics, amino acid digestibility, and ileal microflora composition of broilers
(2019-07-09)
Subtherapeutic antibiotics have been added to diets to improve growth performance of broilers. Pressure from the food service industry is reducing the use of this practice, so the broiler industry is evaluating alternatives ...
The Effects of Phytase and Non-starch Polysaccharide Enzymes in Poultry Production
(2021-11-19)
Feed is the largest expense in broiler production; therefore, feed additives have become commonplace in broiler diets to reduce feed cost and improve live performance. Exogenous enzymes have been used for over 50 years to ...
Effects of Supplemental Xylanase in Corn- and Wheat-Based Diets on Growth Performance and Cecal Volatile Fatty Acid Concentrations of Broilers during a Six-Week Production Period
(2018-06-26)
Supplemental xylanase has increasingly become an important part of diet formulation due to its ability to mitigate the anti-nutritive effects of arabinoxylans, increase energy utilization, and improve growth performance ...
Effects of the soy phytoestrogen genistein on the reproductive development of immature female broiler chickens
(2007-05-15)
Developmentally inappropriate exposures to estrogenic compounds are known to alter morphology and function of the reproductive tract in various species. Chickens are continually exposed to the relatively potent estrogenic ...
Efficacy of bacteriophage treatment in reduction of Salmonella populations on poultry parts
(2014-12-04)
In 2011, the Centers for Disease Control and Prevention (CDC) released updated statistics detailing foodborne illness occurrence and attribution in the United States. From this compilation of data, the CDC concluded that ...
The Efficacy of DL-Methionine Methylsulfonium Chloride on Performance Characteristics and Intestinal Tract Integrity in Broilers
(2007-05-15)
DL-methionine methylsulfonium chloride (MMSC) is a methionine derivative previously shown to modulate the immune system and to protect intestinal membrane cells in humans and swine. It has also been shown to improve body ...
Efficacy of Essential Oils and Cold Plasma to Improve Food Safety of Produce, Raw Beef and Ready-to-eat Meat by
(2021-08-02)
Foodborne diseases remain problematic in the U.S., resulting in illness, financial losses, and in some circumstances, death. Food processors have used traditional methods of chemical additives and thermal processes to ...
Efficacy of Liquid Smoke as an Ingredient in Hotdogs against Listeria monocytogenes and its Effects on the Microbial Shelf-life and Quality Attributes
(2012-04-02)
Research was conducted to study the efficacy of a commercial liquid smoke as an ingredient in hotdog manufacture against L. monocytogenes as well as its effect on the microbial shelflife and quality attributes during ...
Electronic Tongue Analysis of Major and Minor Steviol Glycosides and Their Application in Foods
(2022-07-22)
The electronic tongue (E-tongue) is a taste-sensing analytical device that simulates the human tongue. It has been predominantly adopted in food industries as a tool for taste evaluation. Significantly, some products causing ...
