Intestinal Microbiota Analysis Of Broiler Chickens Under Necrotic Enteritis Challenge And Tributyrin Supplementation, Taylor Nicole Mckinney Aug 2022

Intestinal Microbiota Analysis Of Broiler Chickens Under Necrotic Enteritis Challenge And Tributyrin Supplementation, Taylor Nicole Mckinney

Graduate Theses and Dissertations

Poultry is a staple protein source for most of the planet. Until recently, antibiotic growth promoters (AGPs) were used to prevent illnesses in commercial chicken production. Currently, this is not possible due to regulations and consumer concern, but without such a preventative, diseases like necrotic enteritis (NE) have reemerged, posing a threat to bird health, and ultimately, our food source. Necrotic enteritis is a severe gastrointestinal disease caused by the gram-positive pathogen, Clostridium perfringens. Clinical features of this disease are diarrhea, intestinal lesions, and death, with a high transmission rate. In a subclinical form, growth performance is diminished and is …


“The Role Of Poultry On Food Insecurity In Mozambique”, Austin Heinisch May 2021

“The Role Of Poultry On Food Insecurity In Mozambique”, Austin Heinisch

Finance Undergraduate Honors Theses

Hunger, poverty, and starvation in developing countries are some of the most prevalent challenges facing the world today but many people outside of these areas are not fully aware as to just how bad it is. In the country of Mozambique, where the following research took place, food insecurity levels are rampant, and many different groups/companies are trying to change that. Through a service-learning study abroad program in the summer of 2019, my group and I worked with the local company New Horizons to research ways in which poultry production for both the company and their rural out growers could …


Chickens Play To The Crowd, Cinzia Chiandetti Jan 2018

Chickens Play To The Crowd, Cinzia Chiandetti

Animal Sentience

The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.


Sentience Does Not Require “Higher” Cognition, Giorgio Vallortigara Jan 2017

Sentience Does Not Require “Higher” Cognition, Giorgio Vallortigara

Animal Sentience

I agree with Marino (2017a,b) that the cognitive capacities of chickens are likely to be the same as those of many others vertebrates. Also, data collected in the young of this precocial species provide rich information about how much cognition can be pre-wired and predisposed in the brain. However, evidence of advanced cognition — in chickens or any other organism — says little about sentience (i.e., feeling). We do not deny sentience in human beings who, because of cognitive deficits, would be incapable of exhibiting some of the cognitive feats of chickens. Moreover, complex problem solving, such as transitive inference, …


Are Chicken Minds Special?, Rafael Freire, Susan J. Hazel Jan 2017

Are Chicken Minds Special?, Rafael Freire, Susan J. Hazel

Animal Sentience

The number of publications on chicken cognition and emotion exceeds that on most birds and is comparable to the number of publications on some more “advanced” mammals. We argue that the chicken is an excellent model for this type of research because of (1) the presence of well-established fundamental mental processes in the chicken, (2) a challenging ethological environment and (3) social pressures that may have facilitated the evolution of cognitive abilities similar to those of some mammals. Marino’s (2017) review provides an excellent foundation for the continued study of complex mental abilities in this species.


Getting To The Other Side, Debra Merskin Jan 2017

Getting To The Other Side, Debra Merskin

Animal Sentience

Marino’s comprehensive, detailed, and timely review provides clear evidence of the sentience of chickens and strong support for those wishing to challenge their exclusion from even the limited protections currently accorded to animals grown for food.



Effect Of Light Intensity On Production Parameters And Feeding Behavior Of Broilers, Maurice Raccoursier Frost Dec 2016

Effect Of Light Intensity On Production Parameters And Feeding Behavior Of Broilers, Maurice Raccoursier Frost

Graduate Theses and Dissertations

This project was performed in two parts. The first was focused on light intensity as it affects performance. A randomized complete block design (RCBD) was performed. Broilers, Cobb 500 (n = 1584) were housed in 3 commercial houses (121.9 x 12.2 m). In each house birds were randomized and placed in 72 pens of 121.9 x 121.9 cm (22 bird/pen, males and females). All the treatment groups were provided with 24h light (L) during the first week and then 18L:6Dark (D) and 20 lux from day 7 to 14. The 3 intensity treatments of 5 lux (lx), 10 lx and …


The Ability Of Select Probiotics To Reduce Enteric Campylobacter Colonization In Broiler Chickens, Sandip Shrestha Jul 2015

The Ability Of Select Probiotics To Reduce Enteric Campylobacter Colonization In Broiler Chickens, Sandip Shrestha

Graduate Theses and Dissertations

Campylobacter is the leading cause of foodborne illness worldwide and is often associated with consumption and/or mishandling of contaminated poultry products. Probiotic use in poultry has been an effective strategy in reducing other enteric foodborne pathogens but not consistently for Campylobacter. As Campylobacter resides and utilizes intestinal mucin for growth, isolates selected on the basis of mucin utilization might be a strategy to screen for efficacious probiotic bacterium. In this study, bacterial isolates demonstrating increased growth rates in mucin, in vitro (trials 1 or 2), or isolates demonstrating a reduction of Campylobacter counts when co-incubated with mucin, in vitro (trials …

Efficacy Of Beta-Resorcylic Acid To Reduce Campylobacter Jejuni In Pre-Harvest And Post-Harvest Poultry, Basanta Raj Wagle Jan 2015

Efficacy Of Beta-Resorcylic Acid To Reduce Campylobacter Jejuni In Pre-Harvest And Post-Harvest Poultry, Basanta Raj Wagle

Graduate Theses and Dissertations

Campylobacteriosis is one of the leading foodborne illnesses in United States, and is associated with the consumption of poultry and poultry products. Reducing Campylobacter in these species will reduce the burden of this disease. Unfortunately, most strategies employed to reduce Campylobacter in poultry have either not been successful or produced inconsistent results. One potential control strategy is the use of β-resorcylic acid (BR), a phytophenolic compound classified by the US FDA as "Everything Added to Food in the United States" (EAF 3045) and is therefore deemed safe for consumption. This compounds has antibacterial activity against Salmonella, however, its efficacy to …

The effects of three different meat-containing breakfast meals (pork, beef or chicken) on acute satiety and appetite regulatory hormones were compared using a within-subjects study design. Thirty fasting non-smoking pre-menopausal women attended a research centre on three test days to consume, a meat-containing meal matched in energy (kJ) and protein content, palatability, and appearance. No difference was found between meat groups for either energy intake or macronutrient profile of food consume data subsequent ad libitum buffet lunch, or over the rest of the day. Visual Analogue Scale(VAS) ratings for hunger and satiety over an 180min period did not differ between …

Food, Health And Nutrition: Where Does Chicken Fit?, Karen E. Charlton, Yasmine Probst, Linda C. Tapsell, Patrick J. Blackall Apr 2013

Food, Health And Nutrition: Where Does Chicken Fit?, Karen E. Charlton, Yasmine Probst, Linda C. Tapsell, Patrick J. Blackall

Karen E. Charlton

The link between diet and health is important, given the prevalence of diet related disease, including obesity, in the Australian population. Consumers need to be able to discriminate between foods based on the nutritional contribution of each to a healthy diet. They also need to be able to discriminate between foods in a broader context, considering issues such as food safety, how the food is produced and the environmental consequences of its production. This review outlines the position of chicken in the Australian diet from a health, consumer and environmental perspective. Chicken can contribute to a healthy eating pattern. It …


'Just Don't Eat Chicken': The Challenge Of Engaging Australian Adults In Appropriate Preventive Behaviours For Bird Flu, Sandra Jones, Donald Iverson, Louise Waters Jun 2012

'Just Don't Eat Chicken': The Challenge Of Engaging Australian Adults In Appropriate Preventive Behaviours For Bird Flu, Sandra Jones, Donald Iverson, Louise Waters

Don C. Iverson

Leading medical experts have cautioned about the risk of inappropriate behavioural responses as a result of fear of avian influenza (bird flu) even before a pandemic emerges, and have emphasised the need for appropriate risk communication strategies. There is a paucity of in-depth qualitative research into the general public's understanding of, and reactions to, such potential health crises. Four focus groups were conducted in April 2006 and a further eight focus groups in July 2006, to examine people's knowledge, beliefs and behaviours in relation to avian influenza, with the primary aim being to inform the development of future communication strategies. …
