Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon Oct 2023

Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon

Proceedings of the Arkansas Nutrition Conference

Poultry industry is rapidly moving towards utilizing the best ingredients to precisely feed the birds for better performance, welfare, health, and profitability. One of the practices that evolved over time with research is better optimization of amino acid utilization in the diets thus changing the crude protein landscape. Historically, if we compare the modern diets to diets from 1980, significant changes are visible in the use of unbound or crystalline amino acids leading to reduced levels of CP and reduced unutilized nitrogen in the diets. Multiple feed-grade amino acids are available in a cost-effective manner in poultry diets. Multiple research …


Evaluation Of Selected Nuproxa Feed Additives For Protection Against Lameness And Improving The Wellbeing Of Broilers In A Lameness Challenge Model, Jaren Hernandez May 2022

Evaluation Of Selected Nuproxa Feed Additives For Protection Against Lameness And Improving The Wellbeing Of Broilers In A Lameness Challenge Model, Jaren Hernandez

Biological Sciences Undergraduate Honors Theses

A common concern in commercial industries profiting from broiler chickens is their inability to yield a completely healthy flock. Bacterial Chondronecrosis with Osteomyelitis poses a threat to these companies by impairing the birds' proximal and distal tibial and femoral heads. In 2000, roughly 17.3% of broiler chickens were affected by Bacterial Chondronecrosis with Osteomyelitis which caused a substantial economic loss in the industry (McNammee et al., 2000). BCO cannot be tied to a particular bacterial species; this experiment focuses on evaluating the efficacy of certain commercial feed additives while determining the bacterial species causing BCO in this set of the …


Free Fatty Acid Removal From Oil Using Magnetic Nanoparticles, Daniel Sabo Aug 2021

Free Fatty Acid Removal From Oil Using Magnetic Nanoparticles, Daniel Sabo

Proceedings of the Arkansas Nutrition Conference

Unprocessed crude oils consist of some amount of triglycerides as well as free fatty acids (FFAs). FFAs are virtually absent in oils from living tissue. They are formed by enzymatic action after the animal has been slaughtered. Hydrolysis of ester bonds in lipids, which results in the formation of FFA from the triglycerides, may be caused by enzymatic action, heat, or moisture. This release of short-chain fatty acids is the reason for rancid flavor and odor. Furthermore, the presence of FFAs can self-catalyze and release more FFAs from triglycerides. FFAs are susceptible to oxidation, which leads to oxidative rancidity. This …


Incorporation Of Hempseed In The Broiler Chicken Diet, Mallorie Alexzandra Snider Jan 2020

Incorporation Of Hempseed In The Broiler Chicken Diet, Mallorie Alexzandra Snider

Murray State Theses and Dissertations

Hempseed has become a popular supplement alternative due to the confounding nutritional benefits it possesses; however, the legality of hempseed, and other hemp products, prevents the use in animal feeds. Particularly, broiler chickens that grow fairly quickly in a short amount of time. Evaluation of hempseed in the broiler chicken diet is needed to conclude if it is a possible replacement for other broiler nutrient sources, such as soybean meal (SBM). Thus, the objective of this study was to evaluate the effects of hempseed (HS) on the growth, feed conversion and carcass yield of broilers. This study consisted of 48 …


Detection Of Two Pathogens Of High Importance To The National Poultry Improvement Plan: Salmonella Spp. And Mycoplasma Spp., Robin Levi Jarquin Dec 2011

Detection Of Two Pathogens Of High Importance To The National Poultry Improvement Plan: Salmonella Spp. And Mycoplasma Spp., Robin Levi Jarquin

Graduate Theses and Dissertations

In 1935, the National Poultry Improvement Plan (NPIP) was created to control Salmonella gallinarum and Salmonella pullorum . These two pathogens were devastating economically for poultry producers. Through cooperative efforts using vaccination and strict biosecurity, these two pathogens were eradicated from the United States. Currently, the NPIP program is targeting two other poultry pathogens, Salmonella enterica serovar Enteritidis and Mycoplasma . In the broiler industry it targets 2 specific Mycoplasma species (synoviae, gallisepticum). Vaccinations for these bacteria are available, but are not fully effective at controlling all strains and serovars. Thus, constant monitoring systems and strict biosecurity measures are necessary …

Why Some Hens Lay More Eggs Than Others, H. E. Alder Nov 1932

Why Some Hens Lay More Eggs Than Others, H. E. Alder

Nebraska Agricultural Experiment Station: Historical Circulars

The 1929 report of the Storrs Egg Laying Contest, which has been conducted at Storrs, Connecticut, twenty-one years, shows that the best pen of ten hens entered laid 2,802 eggs, and the poorest pen laid 829 eggs. In the best pen the average egg production per hen was 280, 2 eggs as compared with 82.9 eggs per bird in the poorest pen. Why did the one pen lay so many eggs, and the other so few? This prompts us to try to find out what factors are responsible for the number of eggs a hen lays in the course of …


Better Rations - More Eggs, F. E. Mussehl Oct 1925

Better Rations - More Eggs, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Well-bred and well-fed hens are conceded to be economical producers of a very wholesome food product, eggs, but our hens are not miracle workers and they insist on the right kind of raw material for building the egg. Nebraska poultry growers fortunately have all the natural feeds - corn, wheat, oats, barley, and dairy and packing house by-products - readily available at lower cash prices than prevail in most other states, and so our special problem is that of combining them so that eggs may be produced at the lowest cost per dozen.
