Genetic and environmental factors affecting age of first estrus,
wool production, reproduction and lamb production were examined in
eight groups of crossbred ewe lambs from two birth years. The 399
ewe lambs whose first year production was analyzed were from eight
crossbred groups resulting from mating North Country Cheviot, Dorset,...
The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
Two concurrent trials were conducted to examine genetic and
environmental influences on growth rate, carcass fatness
and muscle fiber type proportions. Trial 1 compared
Polypay and Coopworth x Polypay male lambs either left
intact or castrated early, mid or late in growth. Trial
two compared Hampshire sired lambs (females, early...
The objectives of this study were to investigate the effects of
the by-product, ryegrass straw, and the feed additive, monensin, on the
performance of feedlot lambs.
Four pelleted rations were fed ad libitum: Ration 1 - 50% barley,
50% alfalfa hay; Ration 2 - 50% barley, 50% alfalfa hay and...
Callipyge (CLPG, n=16) and normal (N, n=11) lambs were
produced from Polypay dams and Dorset sires heterozygous for
the CLPG gene to study the effects of the gene on growth and
carcass and meat quality parameters. CLPG lambs had higher
average daily gain than N lambs (0.26 vs 0.23 kg/day,...
A survey of Oregon sheep producers conducted as part of this research, indicated that lambing losses by sheepgrowers in winter rainfall areas of Oregon currently average 16 percent. The majority of the lambs born in these areas are born in pastures without the benefit of shelter. The utilization of portable...
A high performance liquid chromatography (HPLC)
procedure using a LiChrosorb-NH₂ column and a eluant
buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH
5.95, was developed for the successful separation and
determination of ascorbic and erythorbic acids in selected
food samples.
Application of the method, which is sensitive, rapid
and...
Thirty-six female guinea pigs were placed on a scorbutogenic
diet for 14 days and then divided into groups of four. Three groups
received adrenocorticotropic hormone (ACTH) with each group given
10, 20, or 40 units. Three groups each received 50 mg of ascorbic
acid and three groups received 50 mg...
