The effect of early protein restriction on poult performance and mortality due to spontaneous turkey cardiomyopathy were examined in a facility that historically had a high incidence of the condition. Two thousand male turkey poults were divided into two equal subgroups for the first 4 weeks of life: one received standard commercial rations for the first 4 weeks (high-protein subgroup), and the other received rations with a protein content approximately 70% of the first subgroup (low-protein subgroup). Rations were the same after 4 weeks of age (standard commercial rations). At 16 weeks of age, turkeys in the low-protein subgroup weighed an average of 12.32 kilograms (27.1 pounds), whereas turkeys in the high-protein subgroup weighed an average of 12.73 kilograms (28.0 pounds). Total mortality for the low-protein subgroup was 10.1%, whereas total mortality for the high-protein subgroup was 15.7%. Total mortality due to spontaneous turkey cardiomyopathy in the high-protein subgroup was greater than twice that in the low-protein subgroup (10.4% versus 4.6%). These results show that lowering the protein content of the feed in the first 4 weeks significantly reduces mortality due to spontaneous turkey cardiomyopathy, but body weight gain is also reduced.

D009202	Cardiomyopathies	A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).

D011201	Poultry Diseases	Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
