Advances in genetic selection make today's pullets quite different from those of only a few years ago. Pullet body weight is less. Age at housing and at 5 percent production are earlier. Total egg numbers are increasing, egg mass is greater, and feed conversion has improved.
Advances in genetic selection make today's commercial layers quite different from those of a decade ago. Body weight is less, age at housing and age at 5 percent production are earlier, total egg numbers have increased, egg mass is greater, and feed conversion has improved considerably.
"Feed passage," or, more accurately, the passage of undigested feed in the feces of broilers, continues to be reported in broiler integrations on a sporadic basis. The incidence and severity are much lower at present than during 1996 when global reports of feed passage occurred following consecutive years of poor grain harvests.
Poultry feeds are referred to as "complete" feeds because they contain all the protein, energy, vitamins, minerals, and other nutrients necessary for proper growth, egg production, and health of the birds. Feeding any other ingredients, mixed with the fee
The old saying, "you are what you eat" relates not only to humans but also chickens. Feeding programs for broilers, breeders, and layers are more than buying, blending, and scheduling feed.
