Effect Of Pig Weaning Age And Commingling After The Nursery Phase On Humoral And Behavioral Indicators Of Well-Being And On Growth Performance, Sarah C. Arthur, Mari E. Davis, Jason K. Apple, Charles V. Maxwell
Effect Of Pig Weaning Age And Commingling After The Nursery Phase On Humoral And Behavioral Indicators Of Well-Being And On Growth Performance, Sarah C. Arthur, Mari E. Davis, Jason K. Apple, Charles V. Maxwell
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Two hundred and sixteen pigs were weaned at 14 or 21 d of age to determine the effect of weaning age and commingling after the nursery phase on growth and behavior of pigs in a wean-to-finish facility. Pigs were divided into older and younger age groups and allotted 12 pigs/pen with nine replications of each group. At the end of the nursery phase (d 34 after weaning), one-half of the pigs in each group were removed and commingled for the grower/finisher phase and the other half remained in their original pens. Beginning at weaning (d 0), pigs were monitored via …
Laboratory-Scale Evaluation Of Incandescent And Compact Florescent Lamps For Poultry House Lighting, Leanne Gabriel, Donald M. Johnson
Laboratory-Scale Evaluation Of Incandescent And Compact Florescent Lamps For Poultry House Lighting, Leanne Gabriel, Donald M. Johnson
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
This laboratory-scale study compared 1000- and 2000-h rated 60W incandescent lamps and 6000-h rated 60W-equivalent compact florescent lamps over 6000 h of simulated broiler-house operation. The four original 1000-h incandescent lamps were replaced 22 times and the four 2000-h incandescent lamps were replaced 14 times. None of the four compact florescent lamps failed during the 6000-h experiment, although one was broken due to human error. Both types of incandescent lamps had significantly higher (p < .0001) mean illuminance (lx) than did the compact florescent lamps. The compact florescent lamps used significantly less (p < .0001) power (W) and had significantly higher (p < .0001) efficiency (lx/W) than the incandescent lamps. Despite a higher initial purchase price, the total cost (purchase + replacement + electrical) of operating compact florescent lamps was approximately 36% lower than the total cost of operating either type of incandescent lamp over the 6000 h period. The results of this study indicate that even at a least-cost price for electricity ($0.04/kW/h), growers can reduce total broiler-house lighting costs by replacing incandescent lamps with compact florescent lamps.

Aerobic Stability Of Heat And Orchardgrass Round-Bale Silage, Robert T. Rhein, Wayne K. Coblentz, Charles F. Rosenkrans Jr., D. Wayne Kellog
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
In Arkansas, silage is typically stored as balage in long rows of round bales wrapped in plastic film. It is important to evaluate the aerobic stability of this fermented forage when it is exposed to air, especially during the winter months when most of it is fed to livestock or sold as a cash crop. Two types of forage, orchardgrass (Dactylis glomerata) and wheat (Triticum aestivum), were harvested in May 2002 and stored as balage. Twenty-one bales of each balage type were unwrapped and exposed to air on 10 Dec. 2002 for 0, 2, 4, 8, 16, 24, or 32 …

Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe
Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe
Journal of the Arkansas Academy of Science
As thermal infrared imaging technology has improved, it has increasingly been used for estimating sizes of wildlife populations. The greatest bias of thermal infrared surveys is the lack of known detection rates to adjust for visibility bias. As with visual surveys, a measure of detection rate is needed to provide unbiased estimates. We assessed the detection rate of white-tailed deer (Odocoileus virginianus) using a thermal infrared sensor (1.2 - 5.9 /an) from an aerial platform. Similar characteristics between thermal signatures of people and deer allowed us to use people in a reclined or horizontal position as surrogates for deer. We …

Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse
Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse
Journal of the Arkansas Academy of Science
The Arkansas Department of Health recorded 118 incidents where humans in Arkansas were treated following exposure to confirmed rabid animals from 1994-2000. Domestic species accounted for 64% of incidents and 76% of total human exposures with the ratio of human exposures per rabid animal 17 times higher for domestic animals than wild animals. Records of 218 cases of human exposure to potentially rabid wild animals during this period were also examined to determine method of contact. While 72% of cases involving raccoons (Procyon lotor), skunks (Mephitis mephitis and Spilogale putorius), and foxes (Urocyon cinereoargenteus and Vulpes vulpes) were initiated by …

Impact Of Dietary Changes On Hepatic Homocysteine Metabolism In Young Broilers, Fauna M. Ganson, Padmakumar Pillai, Jason L. Emmert
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Information regarding the impact of sulfur amino acids (SAA) on hepatic homocysteine (Hcy) flux through the various metabolic pathways competing for Hcy in young broilers is lacking. An experiment was conducted to evaluate the impact of varying levels of dietary methionine (Met), choline, and betaine on hepatic Hcy flux in young broiler chickens. A standard starter basal diet was fed to chicks until 8 d of age; 12 experimental diets were given from 8-22 d. The experimental basal diet contained deficient levels of Met and cysteine (Cys); supplemental Met (0, 0.08, 0.16, and 0.24%) was added to the basal diet …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The northern fowl mite (NFM), Ornithonyssus sylviarum, is a commonly occurring external parasite of chickens. Primarily, caged layers have the greatest incidence of this mite, with bird unrest, unthriftiness and lowered production as some of the adverse effects of the infestation. In the current study, birds with natural NFM infestations were randomized into five treatment groups, placed in individual cages in treatment-specific batteries (all in one room), and evaluated for 28 d for infestation quantification by way of index scoring and feather digest. No treatments were 100% effective in eliminating all life stages of the mite. Tetrachlorvinphos in combination with …

A Survey Into The Prevalence Of Parasitic Helminths In Broiler Breeders, Anita Sarathi, Tom Yazwinski, Chris Tucker, Jennifer Robins
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A survey was conducted to determine the prevalence of helminth infections in spent broiler breeders. Intestinal tracts from 10 birds from each of five farms were obtained and examined for parasite identification and quantification. Heterakis gallinarum infections were the most common, followed in order of decreasing incidence by Capillaria obsignata, Ascaridia galli, and Raillietina cesticillus. Peak worm burdens for individual birds were 121 (A. galli), 535 (H. gallinarum), 215 (C. obsignata) and 125 (R. cesticillus). Significant farm-to-farm variation in worm burdens was observed.
