A simulation model capable of execution on a programmable
calculator was developed to study voluntary intake,
liveweight change, and fertility of grade Zebu cows in the
Llanos of Colombia. Organic nitrogen in the diet and meta
bolic weight were used to predict intake; age, liveweight,
and energy concentration were the...
The records of a population of sex-linked dwarf layers
at the Oregon State Agricultural Experiment Station subjected
to an accelerated selection for hen-housed egg production at
40 weeks of age for a period of over 11 years were analyzed
for selection response, and for the estimation of genetic
parameters. The...
Elasticity properties of wood studs are essential inputs for
the structural analysis of wood-stud wall systems.
A theoretical procedure was developed to determine the probability
distributions for the deflection-load relations of stud samples.
The procedure is based on the finite element analysis and a Monte-
Carlo type simulation and accounts...
The major objectives of this study were: (1) to determine the extent to which southwest Oregon populations of Douglas-fir [Pseudotsuga menziesii var menziesii (Mirb.) Franco) differ in quantitative genetic structure (QGS); (2) to determine whether differences in QGS are associated with the environments from which populations originate; and (3) to...
