Field Studies Of Selected Pathogens For The Control Of The Corn Earworm, Heliothis Zea Boddie, W. Robert Tilyard Jr.

Masters Theses

Tests conducted at the University of Tennessee were designed to compare the control results of the corn earworm by three different pathogens and a standard chemical insecticide. Also, some methods of application were tested. The pathogens tested were a bacterium, Bacillus thuringiensis Berliner, a nuclear polyhedrosis virus specific for Heliothis zea, and the nematode, DD-136.

The treatments were applied under field conditions directly to the ears of corn.

The results indicated that general effectiveness is based on how accessible the pathogens are to the earworm larvae. Best control was accomplished by a treatment using a virus-nematode combination. That treatment …

Some Factors Affecting Hydration And Texture Of Four Varieties Of Dried Beans, Phaseolus Vulgaris L, Chang Lim Yoou

Masters Theses

Great Northern, Navy, Light Red Kidney, and Pinto varieties of beans were used to study the effect of moisture modification on hydration, texture, and "butterflying" of dried beans for processing. Pinto and Light Red Kidney varieties were used to study the effect of hydration in solutions of amylase, cellulase, and pectinase enzymes on water absorption and texture of dried beans. Moisture absorption by dried beans during conditioning and soaking was directly related to intial moisture content. By exposure to saturated humidity for 48 hours, the impermeability of low moisture beans was reversed. Firmness of soaked beans was found to be …

Physiological And Economic Evaluation Of Gross Efficiency In First Lactation Jerseys, Roy Darrell Holder

Masters Theses

Feed intake and production data on 226 first lactation Jerseys fed either an all forage or a forage plus grain ration were analyzed to determine the variation in gross efficiency during portions of the lactation, and to evaluate the association among several measures of economic efficiency.

Gross feed efficiency (FCM/TENE) was highest for cows on the all forage ration, but showed a steady decline throughout the lactation for cows on both rations. Maximum gross efficiency was attained during the first lactation period (1-70 days), and the most rapid decline in gross efficiency occurred from the first to the second period …

Myoglobin Content And Color Of Raw Pork Loin Roasts As Affected By Freezing At Two Rates, Jane Shellabarger Nocito

Masters Theses

Longissimus dorsi and psoas major muscles from fresh and frozen paired pork loin roasts were evaluated for myoglobin content and color reflectance. One of each paired roast was analyzed fresh and the other analyzed after freezing and thawing. Myoglobin in the thaw drip from frozen roasts was measured, also. Two freezing rates were tested: fast freezing in an air blast freezer at -27° to -29°C and slow freezing in a home freezer at -18°C. Roasts were stored for 28 days before thawing.

Myoglobin in the longissimus dorsi was significantly (P < 0.001) lower than in psoas major muscle. Less myoglobin (P < 0.05) was found in fresh than frozen thawed roasts; but there was no difference (P > 0.05) in myoglobin content associated with freezing rate. Apparently, myoglobin …

C. dubius populations from northern West Virginia and southern Pennsylvania were significantly different from populations to the south. …

Magnetic Nonequivalence In Higher Alkyl Groups, Philip Anthony Reitano

Masters Theses

The phenomenon of magnetic nonequivalence has been growing in recent years. Unequal populations of the various conformers in such molecules are normally accepted as the cause of nonequivalence, but nuclei which are stereochemically nonequivalent are not necessarily magnetically nonequivalent. This nonequivalence has been demonstrated for molecules of the type ABDC⁸CHR₁R₂, where R + H, F, and Me. Although in principle the effect is quite general this has not been previously observed in "freely rotating" systems for groups larger than methyl. The role of steric factors, the size of the substituents and the distances between …

Predicting Natural-Mating Efficiency In Beef Bulls From A Sample Of Semen, Dennis Owen Onks

Masters Theses

NIneteen Angus and 14 Polled Hereford bulls were used to determine the relationship of certain semen characteristics with subsequent fertility. Semen samples were obtained from bulls by electroejaculation. Measurements obtained from each sample were volume, concentration (billions per milliliter), percent motility, vigor (degree of motility), and percent abnormal spermatozoa. Cows of various ages and parities were used in single-sire breeding groups for evaluation. Weighted-means adjusted for parity were obtained to evenly weigh the cow herd. These overage values were used to more effectively evaluate the individual bull's potential fertility. The results of this study show that percent abnormal spermatozoa and …

Performance Of Feeder Pigs Of Various Grades, James Tracy

Masters Theses

Production of feeder pigs has become a major swine enterprise in Tennessee. An increasing number of these pigs are being marketed through organized feeder pig sales where they are sorted according to weight and grade. The grade of a feeder pig is determined by evaluating its logical slaughter potential and its thriftiness. The logical slaughter potential of a thrifty feeder pig is its expected slaughter grade at a market weight of about 220 pounds after a normal feeding period. Therefore, the objective of this experiment was to measure the performance, feed efficiency and carcass characteristics of pigs of various feeder …
