Recognizing Healthy and Unhealthy Animals
By Steve Tonn, UNL Livestock Educator
A sound management program to keep animals healthy is basic to production of any livestock. Producers must observe animals closely to keep individual animals and the whole herd or flock healthy and productive. If the health status of a herd is compromised, that operation will not be as efficient as possible.
To recognize clinical signs of diseases common to livestock, it is important to be familiar with what is normal or healthy.
Producers should assess the herd or flock's general health, on a regular basis, including vital signs, body condition and coat.
Egg Cleaning for the Backyard Flock
By Kody Sok, UNL Extension Poultry Assistant, and Sheila Purdum, UNL Extension Poultry Specialist
Producing your own eggs can be a rewarding part of raising your own chickens. However, household poultry flocks can produce a high percentage of dirty or tainted eggs (Figure 1). Most of these eggs are soiled because they were laid in dirty nests or on the floor where they may have come in contact with fecal matter. Dirty eggs can be a health hazard if they are not properly washed and sanitized (i.e. harmful bacteria can enter through the pores of the eggs and if not cooked properly have the potential to cause food poisoning).
Heat Stress Management in Broilers
By Gary D. Butcher, D.V.M., Ph.D. and Richard Miles, Ph.D., University of Florida Extension
High ambient temperatures can be devastating to commerical broilers; coupled with high humidity they can have an even more harmful effect. Heat stress interferes with the broilers comfort and suppresses productive efficiency. During periods of heat stress the broiler has to make major thermo-regulatory adaptions in order to prevent death from heat exhaustion. The result is that the full genetic potential of the broiler is often not achieved.
The pupose of this paper is to review some of the effects of heat stress on broilers and methods which can be used by the poultry producer to partially alleviate some of the deterimental effects of heat stress on broiler performance.
