Outbreaks of Human Salmonella Infections Associated with Live Poultry, United States, 1990–2014

Emerging Infectious Diseases Journal,  Centers for Disease and Prevention, Volume 22-Number 10, October 2016

 

BACKGROUND:  Backyard poultry flocks have increased in popularity concurrent with an increase in live poultry–associated salmonellosis (LPAS) outbreaks. Better understanding of practices that contribute to this emerging public health issue is needed. Most chicks sold for backyard flocks are produced by a network of mail-order hatcheries. Disease control guidance for hatcheries is provided by the US Department of Agriculture National Poultry Improvement Plan, which is a voluntary state, federal, and industry cooperative program aimed at eliminating certain diseases from poultry breeding flocks and hatcheries.

Testing Protocol for Disease Surveillance in Poultry

by Dr. Mohamed El-Gazzar

Any surveillance program is intended to be an early warning system that detects the infection as early as possible to allow for timely control and eradication of the infectious agent. The poultry industry relies heavily on surveillance to keep certain diseases out of the population. Avian Influenza (AI), Avian Mycoplasma, and Salmonella are examples of such diseases. Surveillance is an intricate and complicated process that can be different in different diseases and in different situations. In this article we will review the general principals of surveillance programs in poultry and extract the basic concepts by which we can critically examine any surveillance program.

Breed Selections of Chickens

Breed Selection of Chickens

By: Sabrina Schirtzinger, Agriculture and Natural Resource Extension Educator, Knox County

There are various reasons people raise chickens for eggs, meat, and exhibition or simply just for the caring and watching chicks grow. For some raising chickens is a hobby; and others see it as a sustainable part of living.

So, what are your needs? What is your end goal for raising chickens? These questions will help you to determine what category of poultry you are leaning towards.

Is your goal:

Egg Production– These chickens will lay eggs; however, what color egg would you prefer white, light brown, dark brown or colored?

Egg and Meat Production– These chickens are referred to as dual purpose breeds that tend lay an adequate amount of eggs and get large enough for meat production. American chicken breeds where developed for this purpose.

Meat Production– Chickens that are bred solely for meat production. Chickens reach 4-5 pounds in 6 weeks and 6-10 pounds in 8-12 weeks. The best growth rate will come from a Cornish crossed with a White Rock called a Cornish Cross.

Exhibition of Poultry– Showing chickens have becoming popular in the Midwest. The American Poultry Association (APA) has a publication called, The American Standard of Perfection. This book gives you a complete description of all the breeds and varieties of domestic chickens.

Selecting the best breed of chicken can be difficult as there are many to choose from. Understanding their differences will help you to increase you production, reduce your time and save you money. Within in article you will find a chart highlighting a few aspects producers look for in their flocks. This chart is designed to help you come to a decision about which breed is best for your needs.

Wooden Breast Research Update

Histopathologic and Myogenic Gene Expression Changes Associated with Wooden Breast in Broiler Breast Muscles

Sandra G. Velleman and Daniel L Clark

Department of Animal Sciences, Ohio Agricultural Research and Development Center, The Ohio State University, Wooster, OH 44691

Received 20 April 2015; Accepted 20 May 2015; Published ahead of print 21 May 2015

 

SUMMARY. The wooden breast condition is a myopathy affecting the pectoralis major (p. major) muscle in fast-growing commercial broiler lines. Currently, wooden breast–affected birds are phenotypically detected by palpation of the breast area, with affected birds having a very hard p. major muscle that is of lower value. The objective of this study was to compare the wooden breast myopathy in two fast-growing broiler lines (Lines A and B) with incidence of wooden breast to a slower growing broiler Line C with no phenotypically observable wooden breast. One of the characteristics of the wooden breast condition is fibrosis of the p. major muscle. Morphologic assessment of Lines A and B showed significant fibrosis in both lines, but the collagen distribution and arrangement of the collagen fibrils was different. In Line A, the collagen fibrils were tightly packed, whereas in Line B the collagen fibrils were diffuse. This difference in collagen organization may be due to the expression of the extracellular matrix proteoglycan decorin. Decorin is a regulator of collagen crosslinking and is expressed at significantly higher levels in Line A wooden breast– affected p. major muscle, which would lead to tightly packed collagen fibers due to high levels of collagen crosslinking. Furthermore, expression of the muscle-specific transcriptional regulatory factors for proliferation and differentiation of muscle cells leading to the regeneration of muscle in response to muscle damage was significantly elevated in Line A, and only the factor for differentiation, myogenin, was increased in Line B. The results from this study provide initial evidence that the etiology of the wooden breast myopathy may vary between fast-growing commercial broiler lines.

Choosing an Incubator

Choosing an Incubator

Introduction

Hatching chicks can be a rewarding experience, fun and educational for the entire family. Eggs used for hatching are fertilized eggs that hatch only if properly incubated. Fertilized eggs are obtained from reputable outside sources such as hatcheries or breeders, or they may come from your flock.

Shipped eggs have a lower chance of hatching than eggs picked up in person. The less time spent in transport, the better chance of them hatching. Collecting fresh eggs from your flock is the best way to have the highest hatch rate. If stored properly, you can save fertilized eggs until you get enough to set. Typically, hatching percentages continue to decrease the longer the eggs remain out of an incubator.

What Are Your Goals?

Determine your goals before selecting an incubator. There are many styles of incubators, from table top to floor models, ranging in size and price. Ask yourself these questions:

  • What species of fowl do you want to hatch?
  • How many eggs do you plan to set?
  • How many hatches do you want per year?
  • What features do you want an incubator to have?
  • What percent hatch rate do you expect? (A realistic hatch rate is 80-85% if all goes well.)

Purchase the style of incubator that suits your needs before collecting hatching eggs.

 

Factors to Consider

Less expensive incubators generally have fewer features. They might lack an egg turning device and not control temperature and humidity as well as a more expensive incubator. Egg turning, ventilation, temperature and humidity all affect the success of a hatch. When looking at incubators consider the following features:

(1) Egg Type and Capacity—Some smaller incubators handle only chicken eggs without the possibility for modifications. Larger models usually can accommodate any type of egg. Models for home use hold as few as 3 eggs and as many as 250.

(2) Turning—Turning hatching eggs is vital to their survival. Turning keeps the yolk centered within the egg white so it doesn’t stick to the shell membrane and cause the death of the developing embryo. Do you want an automatic turner or will someone be present to turn eggs at least three times a day, every day, until the last 72 hours before hatching? Some incubators come with rotating devices or tilting trays. An egg turner with racks that hold 42 chicken eggs and that move the eggs from side to side can be purchased for use in tabletop Styrofoam incubators. Racks sized for quail, duck, geese, and turkey eggs also can be purchased for certain types of egg turners.

(3) Airflow—A good airflow is very important for developing embryos, as they use up oxygen fairly quickly and simultaneously generate carbon dioxide. Good airflow is needed to continually replenish oxygen and remove the carbon dioxide. All incubators have vents to help circulate airflow. There are two types of incubators in relation to airflow: circulated air incubators and still-air incubators. Circulated air incubators, also known as forced air incubators, have built-in fans that continually circulate air to maintain sufficient oxygen and keep the temperature even. They are more expensive than still-air incubators but produce a better hatch rate. Still-air incubators, also known as gravity-flow incubators, do not have fans to circulate air, but instead rely on circulation that occurs naturally through vents.

(4) Temperature Control—The temperature inside an incubator is extremely important. Fluctuation in temperature or a difference of as little as one-fourth degree can decrease your hatching percentage or cause hatchlings to have health issues and poor survival rates. Incubators are either wafer controlled or electronically controlled. Many table top Styrofoam incubators have a wafer thermostat which you must adjust for a day or two to get the desired temperature inside the incubator. Wafer-controlled incubators allow for more fluctuation in temperature and can contribute to irregular hatches than do electronically-controlled incubators. Once the temperature in a wafer-controlled incubator is set you must be careful to avoid bumping the adjusting screw.

It is a lot easier to manage electronic temperature regulation. Temperatures for some electronically- controlled incubators are preset by the manufacturer for hatching chicken eggs. These can be adjusted for hatching other species of poultry. Others have a temperature-controlled thermometer that works on a relay switch.

Regardless of the type of temperature control in the incubator you purchase, run the incubator for 24-48 hours before adding eggs to make sure the temperature is adjusted correctly. Even with this precaution, minor adjustments may need to be made after adding eggs.

For circulated air incubators follow the manufacturer’s recommendations for temperature settings.

(5) Humidity Control—Developing embryos must have the correct amount of moisture throughout incubation, as does a hatchling to break out of its egg. All incubators should have water-holding devices. Some have troughs built into the bottom of the incubator. Others have containers that can be attached externally to automatically dispense water into the incubator. Some have removable trays, pans, or plastic liners with troughs. If not included with your incubator, purchase a wet-bulb thermometer (hygrometer) to measure humidity in wet-bulb degrees or a digital hygrometer to measure percent relative humidity. Follow the incubator manufacturer’s instructions.

(6) Ability to Observe—Certain brands or models of incubators offer transparent covers or large observation windows to make it easy to check the temperature and humidity and to watch the eggs throughout the incubation time and during the hatch. Opening an incubator because it has very small windows or no windows at all can reduce the hatching percentage. Therefore it is better to purchase an incubator with a larger observation area if you and your family want to observe.

(7) Cleaning Ease—Consider the ease of cleaning when looking at an incubator’s construction. You will need to clean and sanitize your incubator once all of the hatchlings are moved from the incubator to the brooder.

(8) Cost—How much money are you willing to spend to purchase the type of incubator that has the features you want and will best help you reach your incubation and hatching goals?

In Summary

Do your research before deciding on what type of incubator to purchase. Consider your incubation and hatching goals and review the various factors to consider. If possible, talk to others who have used the type of incubator you plan to purchase.

Veterinary Feed Directive

The Veterinary Feed Directive OTC changes go into effect on January 1st, 2017. This has the potential to impact the Poultry Industry.

From www.fda.gov:

Background

Over the past several years, the FDA has taken important steps toward fundamental change in how medically important antibiotics can be legally used in feed or water for food-producing animals. Now, the agency is moving to eliminate the use of such drugs for production purposes (i.e., growth promotion and feed efficiency) and bring their remaining therapeutic uses in feed and water under the supervision of licensed veterinarians – changes that are critical to ensure these drugs are used judiciously and only when appropriate for specific animal health purposes. The Veterinary Feed Directive (VFD) final rule is an important part of the agency’s overall strategy to ensure the judicious use of medically important antimicrobials in food-producing animals.
