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 peripheral-type benzodiazepine receptor (PTBR) of trout brain was
pharmacologically characterized and pyrethroid interaction with this site
investigated. High-affinity binding sites for [³H]PK 11195 were detected in brain
membranes of rainbow trout; these shared some of the characteristics of the
PTBR of rodent brain (i.e., high affinity for PK 11195...
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)...
An experiment was conducted to evaluate a breeder diet
containing a yeast culture as a means of improving the
reproductive performance of two genetically dissimilar lines
of turkey hens (designated as L and H). Two hundred hens of
lines L and H, 100 hens per line, were housed in a...
