VII. CONCLUSIONS<br />
Recent studies on embryonic- and post hatch development <strong>of</strong> broilers have greatly advanced<br />
our knowledge concerning the specific early brooding- and feeding requirements <strong>of</strong> the<br />
modern, high-yield genetic lines. As the lifespan <strong>of</strong> the broiler continuous to shorten, more<br />
and more emphasis must be placed on early nutrition. <strong>The</strong> newly hatched chick has a<br />
physiological, morphological, and metabolically immature gastrointestinal tract which<br />
benefits from a specialized early nutrition concept. Providing feed as early as possible is<br />
associated with better development <strong>of</strong> immune function, thermoregulatory capacity,<br />
resistance to cold stress and improved breast meat yield. It is concluded that specifically<br />
designed prestarter feeds for the first 4-7 days are likely better able to accommodate the<br />
chick’s nutritional requirement during this crucial stage <strong>of</strong> development rather than regular,<br />
traditional starter feeds. Current feeding practices should be adapted accordingly.<br />
