Faunistic And Morphological Studies On Ciliates (Protozoa, Ciliophora) From A Small Pond, With Responses Of Ciliate Populations To Changing Environmental Conditions, Naci̇ye Gülkiz Şenler, İsmai̇l Yildiz
Turkish Journal of Zoology
Sixty-nine ciliate species were identified in 19 samples from a small pond covered by Lemna minor in Van, Turkey. Statistical analysis was employed to examine the relationships between ciliates and the physical and biological parameters. Total ciliate abundance appears to be related mainly with physical and biological factors such as the dissolved oxygen in the bottom layer and the volume of Lemna and temperature in the surface layer. Some species were investigated in detail using live observation, silver impregnation, and morphometry.

Turkish Journal of Zoology
Morphological, biometrical, karyological, bacular and phallic aspects of Apodemus mystacinus populations in Turkey were studied based on 117 specimens. The biometrical and phallic comparisons confirmed the distinctness of A. m. mystacinus and A. m. epimelas. The UPGMA tree divided populations in Turkey into 2 groups. The distance (D) between A. m. mystacinus and A. m. euxinus was 0.469. A. mystacinus had karyotypic values of 2n = 48, NFa = 50, and NF = 52. Being different from A. m. epimelas, there was a short groove in the dorsal view of the phallus in populations of A. m. mystacinus in Turkey.

Least Shrew (Cryptotis Parva ) In Extreme West-Central Nebraska, Keith Geluso, Jeremy A. White, Michael A. Bogen
Biology Faculty Publications
During the past 35 years, the least shrew (Cryptotis parva) has expanded its distribution along riverine and other mesic corridors in western parts of its distribution, although some recently discovered populations in the West might represent relicts of a previous Pleistocene distribution. In Nebraska, the least shrew originally was known only from eastern and central parts of the state, but recent records are now available from extreme west-central Nebraska and the northwestern corner of the state. Our record from west-central Nebraska probably represents recent westward expansion of C. parua along the North Platte River. This capture in Scotts …

Roadside Bias In Point Count Surveys At Arrowwood National Wildlife Refuge, North Dakota, J. Scott Dieni, Paulette Sherr
United States Fish and Wildlife Service: Publications
We investigated potential biases of using roadside point counts to sample breeding bird populations in the northern mixed··grass prairie. In 1995, a breeding bird inventory and monitoring program was initiated at Arrowwood National Wildlife Refuge, east-central North Dakota. Surveys were conducted annually through 1998 from an extensive point count array permanently located across the refuge (n = 162). Fifty-nine percent of the point counts were established directly on tertiary dirt roads and trails, while the remaining were interspersed at randomly selected distances of 100, 200, 300, and 400 m away from roads. Roadside point counts commonly consisted of a mosaic …

Bufflehead Breeding Activity In South-Central North Dakota, Gregory A. Knutsen, Janet C. King
United States Fish and Wildlife Service: Publications
The bufflehead (Bucephala albeola) is a small, cavity-nesting diving duck that breeds primarily in the aspen parkland and boreal forest regions of Alaska and Canada (Erskine 1972, Bellrose 1976, Gauthier 1993). According to Gauthier (1993), buffleheads prefer habitat consisting of small, permanent wetlands with a scarcity of emergent vegetation and adjacent aspen or poplar (Populus spp.) stands.
Where Can I Build Or Expand A Livestock Operation? A Case Study Of Cuming County, Nebraska, Christopher G. Henry, Jeff Arnold
Where Can I Build Or Expand A Livestock Operation? A Case Study Of Cuming County, Nebraska, Christopher G. Henry, Jeff Arnold
Nebraska Swine Reports
The impacts that setback distances of 1/4, 3/8, 1/2, 3/4, and 1 mile would have on the land area available to the livestock industry for expansion in Cuming County, Neb. were estimated using a geographic information system and the current county zoning requirements. These setbacks seem to be typical of distances cited in many county zoning regulations. Setback distances greater than 3/8 of a mile appear to be very exclusive to expansion of the livestock industry in Cuming County. Reciprocal setbacks that apply to new housing construction do not appear to be restrictive. It is expected that other Nebraska counties …

Two 4-week experiments were conducted to determine body composition and lysine utilization for protein deposition (PD) in barrows and gilts. Thirty-two growing pigs (16 barrows and 16 gilts; average initial body weight of 40.4 lb) were used in each experiment. Pigs were randomly allotted to one of seven dietary treatments. Four pigs (two barrows and two gilts) were killed at the start and the remaining pigs were killed at the end of the experiments to determine body composition. There were two replications per treatment in each experiment for a total of four replications. Dietary treatments consisted of a basal diet …
Role Of The Gonadotropin-Releasing Hormone (Gnrh) Receptor In Determination Of Ovulation Rate Between Lines Of Swine, Benjamin E. Bass, Ginger A. Mills, Brett R. White
Role Of The Gonadotropin-Releasing Hormone (Gnrh) Receptor In Determination Of Ovulation Rate Between Lines Of Swine, Benjamin E. Bass, Ginger A. Mills, Brett R. White
Nebraska Swine Reports
Litter size plays a major role in the economics of swine production. Even modest increases in average litter size can have considerable effects on overall profitability. Two major components of litter size, 1) ovulation rate, and 2) embryonic survival, have been used in a selection index project ongoing for several generations at the University of Nebraska-Lincoln (UNL). To better understand the mechanisms of one component, ovulation rate, we are investigating the role of the gonadotropin-releasing hormone (GnRH) receptor in determination of this important trait. Although other factors may influence determination of ovulation rate, this receptor has an established physiological importance …
Effect Of Increasing Dietary Crude Protein Concentration On Growth Performance And Serum Insulin-Like Growth Factor-I Concentration, Robert L. Fischer, Phillip S. Miller
Effect Of Increasing Dietary Crude Protein Concentration On Growth Performance And Serum Insulin-Like Growth Factor-I Concentration, Robert L. Fischer, Phillip S. Miller
Nebraska Swine Reports
This study was conducted to investigate the effects of increasing dietary protein intake on growth performance and serum insulin-like growth factor-I (IGF-I) concentration in growing-finishing gilts. Thirty-nine crossbred gilts with an initial body weight of 74.3 lb were used in a 28-day growth study. The gilts were randomly allocated to one of five dietary treatments. The diets were standard corn soybean meal diets, which were formulated to contain 10, 14, 18, 22, or 26% crude protein by changing the ratio of corn to soybean meal in the diet. Pig and feeder weights were recorded weekly for the determination of average …

Nebraska Swine Reports
Pigs treated alike vary in performance due to their different genetic makeup and to environmental effect we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an “equal” group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

Supplementation On Sow And Litter Performance, Subsequent Weanling Pig Performance And Intestinal Development After An Immune Challenge, Steve J. Kitt, Phillip S. Miller, Robert L. Fischer
Nebraska Swine Reports
Sixteen sows were randomly assigned to two treatments: CON: Control corn-soybean meal diet; GLN: Cornsoybean meal diet + 2.5% crystalline glutamine. No differences (P > 0.10) between treatments were observed for sow weight loss, sow feed intake, or litter weight gain. Sow plasma glutamine concentration tended to be increased on days 7 and 21 (P < 0.13) in sows fed GLN. Milk glutamine concentration was increased (P < 0.08) on days 7 and 21 of lactation. However, suckling pig plasma glutamine concentration was not altered (P > 0.38) on day 21 by glutamine enriched milk consumption. On day 21, pigs were weaned to a common starter diet, sow treatment structure was maintained, and two additional treatments were imposed on weanling pigs and arranged in a 2 x 2 factorial: SAL: Saline injection on …
Team Approach To Management, Allen Prosch
Team Approach To Management, Allen Prosch
Nebraska Swine Reports
Managerial ability has been described as consisting of supervision and coordination. The coordination aspect is that function of deciding what business arrangements should be entered into. Pork producers are being called on to justify their right to do business with records that assure society that they have complied with regulations and used best management practices. Coordinating all the business activities to ensure compliance challenges the ability of any manager. The greater need for coordinating ability strongly suggests that pork producers who develop greater coordinating capacity will have a competitive advantage. Team management will be a necessary component in creating that …
Crop Residue Cover And Manure Incorporation — Part Ii: “Fine-Tuning” The System, David P. Shelton
Crop Residue Cover And Manure Incorporation — Part Ii: “Fine-Tuning” The System, David P. Shelton
Nebraska Swine Reports
Manure incorporation represents a compromise between best management practices for soil erosion control and manure management. Manure should be incorporated into the soil for odor control, increased availability of nutrients, and control of potential manure runoff. However, soil and crop residue disturbance should be minimized for soil erosion control. Values to estimate the amount of residue cover that will remain following the use of common manure application/incorporation components have been presented in the article titled “Crop Residue Cover and Manure Incorporation — Part I: Reduction of Cover.” This article discusses some of the influence that injector/ applicator spacing, tire spacing, …

Crop Residue Cover And Manure Incorporation — Part I: Reduction Of Cover, David P. Shelton
Nebraska Swine Reports
Manure incorporation represents a compromise between best management practices for soil erosion control and manure management. Manure should be incorporated into the soil for odor control, increased availability of nutrients and control of potential manure runoff. However, soil and crop residue disturbance should be minimized for soil erosion control. This field study was conducted to: 1) determine the influence that commercially available soil-engaging components used to simultaneously apply and incorporate manure have on the reduction of crop residue cover [Part I - this article]; and 2) determine and evaluate some of the factors that may influence the amount of residue …

Thermal Conditions Within Pens Fitted With Differing Zone-Heating Options And Resulting Performance Of Newly Weaned Pigs In A Wean-To-Finish Facility, Richard R. Stowell, Sherri Colgan, Mike Brumm
Nebraska Swine Reports
Research was conducted to assess the effects of the type of zone heater and floor mat used in a wean-to-finish building on the thermal environment created for newly weaned pigs and resulting pig performance. Gas-fired brooder heaters were compared to electric heat lamps and farm-cut wood sheathing was compared to commercial [unheated] rubber floor mats. No consistent differences in air temperature near the heating zone were found between either of the treatments. However, black-globe temperatures in pens having gas-fired heaters and/or wood mats were consistently warmer than in their comparison pens. Temperature deviations during the 26-day study period were similar …
