Newly Hatched Chicks and Early access to Feed

Newsletter No. 50 Item 4

A quote from the article published here:

Quote:  The small intestine of the newly-hatched chick is immature and undergoes significant morphological, biochemical, and molecular changes during the 2 week post-hatch.

The timing and form of nutrients supplied post-hatch is critical for development of intestines. It has been shown that early access to feed accelerates the rate of yolk utilization and enhances growth of the intestinal tract.

Usual hatchery practices result in a 24-72 hr transition between hatching and placing of chicks on the farm. The delayed access to feed can lead to a depression in intestinal function, which may negatively affect subsequent performance of birds.

Studies have also shown that providing developing embryo with exogenous nutrients (in ovo feeding) may enhance intestinal tract development and lead to higher body weight in ovo fed chicks. End quote

The issues raised in this discussion are:

  • The importance of chick access to feed as soon as possible after hatch
  • The reduced performance of chicks as a direct result of the delay when provision of feed is delayed due to the time taken from hatching to transfer to rearing farm.
  • Studies proving that improved breeder feed to enhance embryo development in the egg may lead to higher body weight in chicks at hatch.

These issues are all very relevant for Ostrich production and confirm again the critical importance of adequate breeder nutrition.
