An experiment was conducted to determine the
suitability of a new variety of yellow pea (Pisum sativum
L., var. Miranda) as a feed ingredient in broiler breeder
diets. Two-hundred twenty-five I S A Vedette dwarf broiler
breeder pullets were fed either a corn-soy (CS) or corn-pea
(CP) diet from day...
I. THE EFFECT OF FEEDING PROGRAMS ON REPRODUCTIVE TRAITS AND
SELECTED BLOOD CHEMISTRIES OF CAGED BROILER BREEDER MALES:
1. FEED RESTRICTION LEVELS:
The effects of five different feeding levels (136, 125, 113,
102, and 91 g/male/day of a 13.1% crude protein (CP), 3167 kcal ME/kg
feed) on the reproductive traits...
Cholesterol, C₂₇H₄₅OH, as a precursor of steroid hormones, and
the genetic implications of a divergent selection program for blood
cholesterol levels provided the purpose of this study.
The initial selection of Japanese Quail for the development of
high and low blood cholesterol lines was from a randomly mated
population of...
A population of Wrolstad strain Medium White turkeys has been divergently selected for low and high mean semen volume for 13 generations. A mean volume difference of .34 mis. was obtained in the 13th generation; with the low line averaging .21 mis. and the high .55 mis. Heritability estimates determined...
Two experiments were conducted to try and
differentiate variations in the levels of total plasma
protein and plasma protein fractions from three lines of
turkeys, each with distinct muscle morphological
characteristics--Deep Pectoral Myopathy (DPM), Hereditary
Muscular Dystrophy (MDY), and a Broad Breasted Bronze
control (J).
Ten day old poults from...
Three experiments were conducted to determine if a new variety of
triticale (Flora) would maintain seminal production of Medium White (MW)
breeder toms and to ascertain the minimal dietary crude protein (CP)
required by breeder toms. In Experiment 1, 4 dietary treatments with 10
males each, were fed ad libitum...
The reproductive performance of four strains of broiler breeder
males (BBM) were compared when housed in individual cages from 22 to
56 weeks of age (WOA), and fed Asi libitum 7% crude protein (CP) diets
with 1985, 2424, 2868 kilocalories (kcal) metabolizable (M) energy (E) per
kg of feed and...
Three distinct studies using an ethidium bromidedigitonin
fluorometric assay were conducted to determine
if the fertilizing ability of individually caged broiler
breeder males (BBM) could be enchanced by nutrition,
breeding and semen extender viscosity.
The first study evaluated the effects on the
spermatozoal quality of BBM by feeding corn-soybean meal...
Two experiments were conducted to determine the
effects of riboflavin and pantothenic acid deficiency
on the production of clubbed down embryos in Single
Combed White Leghorn (SCWL) and Rhode Island Red (RIR)
hens.
In experiment 1, sixteen SCWL and eight RIR hens
were assigned to one of four diets calculated...
The genetic control of changes in unselected traits of
Wrolstad Medium White turkeys divergently selected for
semen ejaculate volumes (SEV) for 16 generations (G) was
studied. Genetic parameters were estimated in G 10 to 14
for embryonic mortality (EM), the incidence of pipped eggs,
and for total plasma cholesterol (PC)...
