Genetic and environmental differences in age at first estrus and in wool and lamb production of crossbred ewe lambs

Creator:: Cedillo, Rose Mary
Abstract:: 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 role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: 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...

Genetic and environmental influences on lamb carcass indices and muscle fiber ratios

Creator:: Arnold, Andrew M.
Abstract:: 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 effects of ryegrass straw and monensin on performance of feedlot lambs

Creator:: Shqueir, Adnan Ali
Abstract:: 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...

Effect of callipyge gene on lamb growth, carcass characteristics, and meat quality

Creator:: Srinivasan, Haribaskar
Abstract:: 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 slatted floor portable shelter for lambing in winter rainfall pastures

Creator:: Nicholson, Martin Theodore
Abstract:: 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...

The effect of erythorbic acid on the determination of ascorbic acid levels in selected foods by high performance liquid chromatography and spectrophotometry

Creator:: Tuan, Shenhsiu
Abstract:: 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...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: 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...
