Homing Studies Of Bank Swallows In Eastern Illinois, Jennifer Eileen Hagerstrom

Masters Theses

A series of homing experiments using 39 color-marked Bank Swallows (Riparia riparia) were carried out in eastern Illinois during the summer of 1975. The swallow colony was located four km east-northeast of Charleston, Illinois at the Charleston Stone Quarry. Eight release sites were located in the four compass directions from the home colony at distances of 14.4 to 32.3 km away.

The colony was approached before dawn and swallows were captured using tube traps. Birds were color-marked, banded, and taken in individual bags to the release site by automobile. Cloud cover, wind velocity, wind direction, and orientation behavior …

Pesticide Residues In The Illinois Wild Turkey, John M. Bridges

Masters Theses

Adipose tissue from 55 turkeys, killed during the 1974 hunting season in southern Illinois, was grouped by age and location of the birds, and the pesticide concentrations in them were determined by gas/liquid chromatography. Twelve different pesticides were identified in the samples with only four, total DDT, heptachlor epoxide, toxaphene, and linuron, being present in all samples. Concentrations ranged from 0.02 ppm to 0.88 ppm.

Number Of Pigs Per Pen With Equal Space Per Pig (1975), B A. Koch, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Groups of 6, 12, or 24 pigs averaging 37 pounds each were assigned to pens where each pig had 3.85 square feet of floor space for a 4-week feeding period. Pigs in groups of 12 gained significantly slower and showed a much higher incidence of tail-biting than groups of 6 or 24. Feed efficiency was similar for all groups. In groups of 12 three pigs per feeder space gave the same results as six pigs per feeder space.; Swine Day, Manhattan, KS, November 13, 1975

Pricing Feeder Pigs (1975), J H. Mccoy, R V. Price, M L. Manuel, C E. Ward

Kansas Agricultural Experiment Station Research Reports

Recent increases in specialized production of feeder pigs has stimulated interest in various methods of pricing pigs outside traditional marketing channels. Most such methods are either negotiated pricing or formula pricing. In privately negotiated transactions, both seller and buyer must have approximately equal knowledge of markets and of grade and weight characteristics of the pigs. In addition, each should have about equal bargaining ability.; Swine Day, Manhattan, KS, November 13, 1975

Trace Mineral Levels During Gestation - Effects On Hemoglobin, Performance And Health Of Neonatal Pigs (1975), D A. Schoneweis, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Thirty-one litters were used to compare effects of two levels of trace minerals fed dams during gestation on hemoglobin, performance, and health of neonatal pigs. There were no significant differences in number of pigs born alive, birth weight, two-week or four-week weights of the pigs due to trace minerals fed the dams during gestation. Neither were there differences between groups of pigs in hemoglobin, packed cell volume, or erythrocytes at birth or at two-weeks age. There were no apparent differences in the incidence of diarrhea or other neonatal diseases between the two group. Our results suggest no benefits from feeding …

Microlite Offered Free-Choice To Growing-Finishing Pigs (1975), B A. Koch, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Growing and finishing pigs consumed from 54 to 64 grams of Microlite per head per day when it was available free choice from a self-feeder. It had no measurable affect on average daily gain, feed consumption, feed efficiency, or behavior of pigs eating a complete ration.; Swine Day, Manhattan, KS, November 13, 1975

Attractants For Swine Starter Feeds: Aroma Vs. Taste (1975), B A. Koch, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Duroc weaned pigs given a choice of feed containing an aromatic or sugar chose diets containing 5% sugar. The preference pattern was altered by pre-weaning feeding in that pigs tended to consume the initial ration. However, they later exhibited a preference for the sugar diet indicating that taste was more of an attractant than aroma. Pigs with access to only one diet consumed approximately the same amount of feed per day, so weight gains and feed/gain ratios were similar. Neither aroma nor sugar increased feed intake or performance by pigs offered only one diet.; Swine Day, Manhattan, KS, November 13, …

Extra Iron For Baby Pigs (1975), B A. Koch, G L. Allee, D A. Schoneweis, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Ten mg. of iron per day fed orally 24 days in addition to 150 mg. injected when pigs were 3 days old did not significantly increase Hb of baby pigs. Neither did it increase average daily gain or weight-per-day-of-age at 32 days. We saw no symptoms of iron toxicity in treated pigs.; Swine Day, Manhattan, KS, November 13, 1975

Isocaloric Swine Finishing Diets With Various Percentages Of Alfalfa Meal And Tallow (1975), B A. Koch, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Increasing the alfalfa meal to 30% in a finishing pig diet did not significantly reduce average daily gain when tallow was also added to maintain the caloric density of the ration. Digestibility of dry matter and gross energy were reduced as fiber increased, but feed efficiency was not significantly changed with caloric density maintained. Increasing dietary alfalfa meal and tallow content did not change the percentage of dietary nitrogen retained. Rations containing high levels of alfalfa meal and tallow tended to "bridge" in self-feeders.; Swine Day, Manhattan, KS, November 13, 1975

Cow And Calf Performance As Affected By Nitrogen Fertilization And Burning Of Bluestem Pastures, L.L. Berger, R.R. Schalles, L.H. Harbers, E.F. Smith, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Burning and fertilizing treatments on six Bluestem pastures were evaluated by comparing performance of spring-calving cows and calves that grazed them. Two control pastures were not burned or fertilized, two pastures were burned, and two were burned and fertilized with 40 pounds of nitrogen an acre, applied aerially. Neither average daily gains of the calves nor reproductive performance of the cows differed significantly among treatments.

Energy Levels And Roughage Sources For Bulls On 140-Day Test, M. Mckee, K.L. Conway, G. Fink, R.R. Schalles, K.K. Bolsen, K.O. Zoellner

Kansas Agricultural Experiment Station Research Reports

Thirty-nine Angus, Hereford, and part Simmental bulls were tested 140 days (December 18, 1973 to May 6,1974) for weight gained. Bulls were divided into four groups and fed four different rations that had been formulated for two energy levels (high and medium) and two sources of roughage (corn silage or oats and prairie hay). Average daily gains (lbs.) on the four rations were: high energy silage, 3.48; high energy oats and prairie hay, 3.27; low energy silage, 2.58; and low energy oats and prairie hay, 3.41.

The Histology Of The Pineal Gland In Odocoileus Virginianus, Terry Michael De Villiers

Masters Theses

A total of 26 pineal glands from the white-tailed deer were histologically examined. Five different stains were utilized to determine various cell types present in pineal tissue. Connective tissue septa divide the pineal gland into incompletely separated lobules which are supplied by a very extensive vascular system. The pinealocyte is the most numerous cell in the gland and is most easily recognized by a prominent nucleus approximately 6-8 microns in diameter. The pinealocyte cytoplasm contains many minute granules. A distinct difference was noted in the histology of the oldest age deer pineal (age 7 years) when globular granules were observed …
