Feeding Chicken Breeders

LAYING HEN BREEDER STRAI S should be fed a dietcontaining about 16 to 17 percent protein with
a Calorie-protein ratio of approximately 50: I. A
breeder ration that has given excellent performance
in flocks is shown in Table l.
A diet to be fed to heavy breeder-broiler type
hens should contain from 18 to 19 percent protein,
Table 1. Directions for the use of a concentrate by
mixing it with corn and sorghum follow. When
modifications are desired because of price and avail-
ability of protein sources, the amino acid content
should be a major factor in the selection or sub-
stitution of a specific protein source.
Energy
The broiler-breeder hen tends to become too
heavy if a high-energy feed is fed. A decrease in
egg production and an increase in mortality may
result. It is recommended that the broiler-breeder
hen diet contain 800 to 900 Calories of productive
energy per pound and the diet for egg-layer breeders
contain 900 to 950 Calories of productive energy
per pound. Experimental and practical feeding tests
have shown that these levels of energy in the breeder
diets produce the most desired results. The major
sources of energy for breeder hen diets are the
various cereal grains, mill by-products, fats and oils.
Economy, availability and mixing facilities dictate
the choice of energy sources. Appropriate changes
in grain sources should be made as their prices and
availabilities vary.
Minerals
Diets for both heavy and light breeders should
be well fortified with manganese and zinc. The
required levels of manganese can be provided by
half pound of feed grade manganese sulfate and
the zinc by three-eighths of zinc sulfate per ton. The
formulas shown in Table 1 have been compounded
to provide adequate levels of calcium and avail-
able phosphorus. Supplemental calcium and phos-

phorus should not be added to these diets, nor
should any calcium source be given free choice.
Vitamins, Antibiotics and Arsonics
The vitamin premix should be packaged in a
10 or 25-pound package, so that the micronutrients
can be distributed evenly in the finished feed. The
vitamin, antibiotics and arsonic acid premix should
contain the following amounts for each ton of
finished feed: stabilized vitamin A, 6,000,000 IU;
vitamin Da, 2,500,000 leU; vitamin E, 5,000 IU;
riboflavin, 4 grams; d-calcium pantothenate, 10
grams; niacin, 30 grams; choline chloride, 600 grams;
vitamin B12, 12 milligrams; vitamin K, 2 grams;
antibiotic, 10 grams; arsonic acid (either 45 grams
of 3-nitro-4-hydroxyphenylarsonic acid or 90 grams
of arsanilic acid.) For mixing the concentrate, two
and a half times these amounts should be made up
in a 25-pound premix package, and one package used
for each ton of concentrate. The 10-pound vitamin
premix packages could be used but would be less
economical and more cumbersome.
