The objective of this study was to compare the total collection
(in vivo), nylon bag, and in vitro digestibility techniques under
standardized conditions. Twin steers were used simultaneously to
measure the digestibility of five rations consisting of the following
ratios of alfalfa hay to steamed roller barley: 4:0 (I), 3:1...
Electrocardiograms from 12 compressed male (CM), 16 compressed
female (CF), ten synthetic compressed female (SCF), nine
brachycephalic female (BF), and 15 dolichocephalic female (DF)
dwarfs from Davis, California, taken in the scapular lead S-II (prescapular
position positive and right forelimb negative) were analyzed,
The data on dwarf electrocardiograms were compared...
Inclusion of substantial levels of raw-frozen Pacific hake
(Merluccius productus) in diets of ranch-raised mink (Mustela vison)
causes a large percentage of animals to develop an abnormal condition
termed "cotton fur" (CF), characterized by depressed body
weight, microcytic-hypochromic anemia and a failure of under-fur
pigmentation. Observations by several groups of...
Most of the nutritionally related difficulties of winter feeding
deer apparently result from either poor acceptability of artificial
rations or digestive disturbances that result from feeding starved
animals feeds to which they are not accustomed. Reported in this
thesis are studies conducted with both captive and wild deer concerning
acceptability...
Six groups of goats were used in the study. These were the normal group (Saanen, French Alpine, and Nubian breeds), 1/4 pygmy group (first backcross to normal), 1/2 pygmy group (F1) 3/4 pygmy group (first backcross to pygmy), 7/8 pygmy group (second backcross to pygmy), and pygmy group0 The mean...
A total of 902 plasma samples from the Rambouillet, Targhee, Columbia, Lincoln, and Suffolk breeds of sheep were analyzed for transferrin type by disc electrophoresis. Six transferrin types, Tf[superscript A], Tf[superscript B], Tf[superscript C], Tf[superscript p], Tf[superscript E], and Tf[superscript P], were found in the Rambouillet, Targhee, and Columbia breeds...
Three trials with wethers and four trials with steers were
conducted to determine some of the effects of sodium bicarbonate,
calcium hydroxide and/or transfer of ruminal contents on ruminant
adjustment to abrupt changes to concentrate rations.
Lambs fed a basal concentrate diet plus sodium bicarbonate had
the highest average feed...
An experiment was conducted to determine if selection from
standardized litters would be effective in separating lines of mice
selected for increased and decreased litter weight at 14 days of age,
and if response to selection on this maternally influenced trait could
be accurately predicted.
Data were collected on litter...
The effects of x-irradiation on quantitative genetic traits was
investigated by comparing the response of irradiated mice to selection
for litter size and 28-day weight with the response to selection
for the same two traits in non-irradiated lines. Irradiated lines
were maintained at three levels of x-irradiation, 25 r, 50...
The investigations were based on a complete diallel cross
among three inbred lines of Suffolk sheep. Line of sire effects were
assumed to be an estimate of general combining ability effects while
sire x dam interaction was assumed to be an estimate of specific
combining ability. The line of dam...
