Ten experiments were conducted to determine the vitamin requirements
of coturnix quail (Coturnix coturnix japonica) to 2 weeks
of age using a glucose monohydrate-isolated soybean protein diet.
A preliminary study consisting of 2 separate experiments was
conducted to determine those vitamins essential to the growing
coturnix. This study revealed that...
A comparison of the various endocrine glands, in addition to
other anatomical measurements, was made on 19 normal and 21
dwarf 2-3-month-old females and 20 normal and 20 dwarf 7-13-month-old females of the White Leghorn breed. At both ages, dwarfs
weighed significantly less and had significantly shorter shanks than
normals....
Studies have been conducted with broilers and layers fed
manually formulated or linear programmed rations. Experiments
with broilers have involved the following: 1) determining the lysine
requirement with and without cottonseed meal in the ration, 2) formulating
by linear programming rations made up from different reported
amino acid mixtures and...
Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations.
Slightly higher fertility...
A series of trials involving Coturnix quail, turkey and chicken
eggs was conducted to determine the effects on hatching performance
of varying amounts of oxygen and carbon dioxide during storage in
plastic bags filled with nitrogen or air. Storage periods of 6 and 13
days were studied in tests involving...
Two lots of six White Leghorn male chickens were fed diets containing
7.3% linoleic acid and either .075% ethoxyquin (lot 1) or 32.4
mg/kg of added vitamin E (lot II) for 47 weeks both of which were
designated as positive controls. A third group (lot III) containing 30
males received...
To observe the effects of oviposition as related to time of insemination
on fertility, four trials were conducted in which individually
caged White Leghorn hens were artificially inseminated with 0.05 cc
of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations
were made at 9:45 a.m. , 10:00...
Several experiments were carried out on Coturnix coturnix
japonica to investigate the effect of selection for growth on a protein
deficient ration. A level of 27% protein was found to be optimum for
three different strains and 17.8% was the lowest protein level used
that allowed for growth and accordingly...
Studies were conducted with Indian River "Hybro" broiler chicks
and Oregon Agricultural Experiment Station dwarf and normal White
Leghorn hens to improve the utilization of white western wheat. Chick
studies were primarily concerned with characterizing the growth
inducing properties of an antibiotic fermentation residue (Vigofac)
which had shown a greater...
An attempt was made to create a hormonal environment of the
uterus comparable to that near the time of natural laying and to
eliminate the effect of a hard-shelled egg on fertilization. Hens without
hard-shelled eggs in their uteri were injected with the posterior
pituitary hormones, oxytocin and arginine vasopressin,...
