Factors That Affect Feed Intake of Meat Birds: A Review

1 Abstract: Feed intake is the major factor that influences both the body weight gain and feed efficiency in meat-type poultry. Because so many factors can influence feed intake, it is often difficult to correct a problem of poor feed intake unless a complete review of feed and management practices is made. Management and flock health issues are usually more likely to reduce feed intake than dietary factors. Dietary factors that influence feed intake would be common among all flocks in a complex rather than on individual flocks. In contrast, environmental or immunological stresses have the most profound effects on flock variation in feed intake. Any management protocol that would alleviate these stressors will improve feed intake. To improve flock feed intake, initially investigate the source of greatest stress or disease challenge.
