The objective of this pilot study was to determine the effect of dietary porcine plasma on circulating insulin-like growth factor 1 (IGF-1) concentrations in gestating sows and characteristics of their litters. Primiparous and multiparous sows were randomly allocated to two treatment groups of sows fed a basal diet or sows fed the basal diet plus 6 g of porcine plasma throughout gestation. On 4 periods during gestation and farrowing, blood was collected for IGF-1 analysis. After farrowing, gestation length, number born, birth weight, and total litter weight were recorded. There were no three-way or two-way interactions between treatments, day of …

Sustainable Farm Practice: Study Of Total And Soluble Phosphorus In A Poultry Farm Equipped With Heavy Use Area Protection Pads, Dover, Delaware, Gulnihal Ozbay, Raju Khatiwada, Lathadevi K. Chintapenta, Eunice F. Handy, Stacy L. Smith

Professional Agricultural Workers Journal

Poultry litter contains high concentrations of water-soluble phosphorus and is readily transported in the farm run-off. This research aims to study the efficiency of heavy use area protection (HUAP) pads in decreasing litter spillage and phosphorous run-off at a Delaware poultry facility. Soil and water samples were analyzed for pH, total phosphorous, orthophosphate, and Mehlich III phosphorous throughout 2012. It has been hypothesized that the efficiency of HUAP pads would be reduced over time. Mehlich III phosphorus ranged from 22.82-200 mg/kg at site I, and 48.17 – 1179.6 mg/kg at site II, which were greater than the optimal soil concentrations. …

Abstract

The study used calibrated Crop Environment Resource Synthesis (CERES) maize (corn) model to simulate maize (corn) physiological growth processes and yields under 2045 and 2075 projected climate change scenarios for six representative counties in Alabama. The future climatologies for two emission scenarios Representative Concentration Pathway (RCP) 4.5 (medium) and RCP 8.5 (high) were developed based on the IPSL-CM5A-MR high resolution climate model. Average yield decreases of 19.5% and 37.3% were, respectively, projected under RCP 4.5 and RCP 8.5 for 2045, and average yield decreases of 32.5% and 77.8% were, respectively, projected under RCP 4.5 and RCP 8.5 for 2075. …

Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell

Professional Agricultural Workers Journal

Abstract

Felling and skidding operations were monitored while clearcut harvesting a 12-acre area of a 14-year old loblolly pine (Pinus taeda) plantation. The study area contained 465 trees per acre for trees 2.0 inches Diameter at Breast Height (DBH) and larger with a Quadratic Mean Diameter (QMD) of 7.26 inches. Two feller-bunchers (tracked and rubber-tired) and two skidders (conventional and large capacity) were paired to create four different harvesting systems which were randomly assigned to 3-acre units for evaluation of production rates and costs. Each system was balanced to determine the number of machines needed to minimize the …

Grazing With Goats Changed The Woodland Plant-Species Composition During Summer, Rishi Khatri, Uma Karki, Jerry Bettis, Yubaraj Karki

Professional Agricultural Workers Journal

Abstract

Woodland grazing is a common practice in the Southeast; however, information is limited on its effects on the woodland plant-species composition. The study objective was to determine the effect of summer grazing on woodland plant-species composition. Before- and after-grazing observations were taken at the ground, mid, and high levels in three plots (1-acre each) along the pre-established transects. Kiko wethers (29, 6-8 months old, 26.8±0.67 kg body weight) were allowed to graze the plots after before-grazing observations were taken. After-grazing observations were taken immediately after the goats were moved out from the plots. Grazing showed a significant effect on …

Economic Impact Of Recreational Fishing In Alabama, Gbenga Ojumu, Diane Hite, Deacue Fields

Professional Agricultural Workers Journal

Abstract

Anglers’ direct mail survey data were used with IMPLAN (Impact Analysis for Planning), input-output system, to estimate the economic impact of recreational fishing in Alabama and the Alabama Black Belt. Separate economic impacts are analyzed for the Black Belt and the State; and direct, indirect, and induced economic impacts were estimated for government revenues, income, and employment. Possible increases in these impacts were also estimated for hypothetically improved recreational fishing sites, using the ‘ideal’ hypothetical site characteristics. The results showed a direct total value added impact of $102.5m; indirect impact of $24.7m, and an induced impact of $8.3m, which …

Modulation Of Colorectal Cancer By The Probiotic Organism Lactobacillus Reuteri, Camara A. Blasingame, Leonard H. Billups, Thomas Graham, Janell Henry, Brianna Carter, David W. Threadgill, A. Deloris Alexander

Professional Agricultural Workers Journal

Abstract

Probiotics are beneficial to gastrointestinal health and have anti-inflammatory properties. An experiment was conducted to determine if L. reuteri could protect mice from azoxymethane-induced colorectal cancer (AOM-CRC). A/J mice were randomly assigned to controls, pre-treatment, or post-treatment groups. The mice in the groups were injected with 10mg/kg body weight of AOM and treated with L. reuteri; given only AOM; given only L. reuteri; or given neither AOM nor L. reuteri. At the end of a 26-week latency period, the mice were euthanized, dissected, and colons examined for tumors. L. reuteri did not protect animals against tumor …

Professional Agricultural Workers Journal

Abstract

The objective was to evaluate the effects of feeding peanut skins (PS) on fatty acid profile of goat meat. The diets used contained 0, 10, 20, and 30% of PS. After 92 days, longissimus muscle (LM), mesenteric adipose (MA), and subcutaneous (SA) tissue samples were analyzed for fatty acid profile. Eighteen (18), 21, and 21 fatty acids were detected in LM, MS and SC adipose tissues, respectively. No changes were detected in the fatty acid profile, but C18:0 increased linearly in LM (p < 0.05) with increasing level of PS whereas C18:1 decreased in the similar manner (p = 0.05). Total saturated fatty acid and monounsaturated fatty acid percentage increased linearly ( …
