FREQUENTLY ASKED QUESTIONS
This problem is commonly referred to as Fatty Liver Hemorrhagic Syndrome. It results when large amounts of fat is deposited in the hen’s liver and abdomen. The liver becomes soft and easily damaged and is more prone to bleeding. The liver contains many blood vessels that rupture easily during egg laying, resulting in massive bleeding and death.
When laying hens are fed diets containing high levels of dietary energy the hens tend to deposit excess energy as fat deposits in their bodies, especially the liver. The problem is more common when feeds containing high levels of corn or other high energy ingredients is fed. Therefore, it is not advisable to feed chopped corn as the sole feedstuff to laying hens.
This condition is observed only in young growing chickens, usually those under six weeks of age. The twisted leg condition is referred to as “perosis” and is caused by a nutritional deficiency of a vitamin named “choline.” This vitamin is important in the formation of cartilage that maintains the stability of the hock or ankle joint.
Perosis appears in only one leg of each affected chick.
Poultry feeds are available with several types of medications for preventing or treating diseases. Coccidiostats and/or antibiotics are the two most common medications added to feeds.
Coccidiosis is hard to control by sanitation practices alone. It is best prevented by feeding a coccidiostat, which is a drug added to feed at low levels and fed continuously to prevent coccidiosis. Feed broilers a ration containing a coccidiostat until the last week before slaughtering. Feed an unmedicated feed during this last week.
Poultry feeds are referred to as “complete” feeds, because they are designed to contain all the protein, energy, vitamins, minerals, and other nutrients necessary for proper growth, egg production, and health of the birds. Feeding any other ingredients, mixed with the feed or fed separately, upsets the balance of nutrients in the “complete” feed. Feeding additional grain or supplement with the complete poultry feed is not recommended.
Feed chicks a “starter” diet soon after they hatch. Continue feeding the starter feed until they reach 6 or 8 weeks of age. The starter diet has the highest level of protein a chicken receives during its lifetime. As the chick matures, it requires a lower percentage of dietary protein and a higher level of energy.
