BREEDER PER­FOR­MANCE & CHICK QUAL­ITY

T he im­por­tance of chelated trace min­er­als

The Poultry Bulletin - - FRONT PAGE -

The em­bryo and day old chick is de­pen­dent on the nu­tri­ents found in the egg for growth and devel­op­ment. There­fore the post-hatch devel­op­ment, growth and sub­se­quent qual­ity of the next gen­er­a­tion broil­ers, lay­ers and breed­ers are de­pen­dent on the health and nu­tri­tion of the breeder hen.

Breeder longevity is a ma­jor fac­tor in­flu­enc­ing op­ti­mal per­for­mance of the breeder hen and as a re­sult chick qual­ity. In or­der to im­prove longevity the hen’s im­mune sys­tem and tis­sue in­tegrity must be in peak con­di­tion. There­fore op­ti­mal nu­tri­tion is a pre­req­ui­site to max­i­mum breeder and prog­eny per­for­mance.

Trace min­er­als are im­por­tant in breeder di­ets to im­prove and main­tain op­ti­mal breeder per­for­mance, as well as egg qual­ity, chick qual­ity and per­for­mance of the next gen­er­a­tion lay­ers, breed­ers and broil­ers (Ta­ble 1).

Tra­di­tion­ally in­or­ganic sources of trace min­er­als, such as sul­phates, are com­mer­cially added to the diet at lev­els 2-10 times more than rec­om­mended re­quire­ment by the NRC. In­or­ganic trace min­er­als dis­so­ci­ate in the crop and giz­zard (low ph) re­sult­ing in in­ter­ac­tions be­tween the trace min­eral and other com­po­nents
