Effects Of Processing Conditions On Single Screw Extrusion Of Feed Ingredients Containing Ddgs, Nehru Chevanan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Kurt A. Rosentrater

Distillers dried grains with solubles (DDGS), a feed coproduct from the fuel ethanol industry, has been shown to be a viable potential alternative protein source for aquaculture feeds. To investigate this, three isocaloric (3.5kcal/g) ingredient blends containing 20, 30, and 40% DDGS, with a net protein adjusted to 28% (wet basis, wb), were prepared for use as Nile tilapia feed. Extrusion processing was then conducted using three DDGS contents (20, 30, and 40%, wb), three moisture contents (15, 20, and 25%, wb), three barrel temperature gradients (90–100–100°C, 90–130–130°C, and 90–160–160°C), and five screw speeds (80, 100, 120, 140, and 160rpm) …

Twin Screw Extrusion Of Ddgs-Based Aquaculture Feeds, S. Kannadhason, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Michael L. Brown

Kurt A. Rosentrater

Six isocaloric (3.65 kcal/g), isonitrogenous (35% dry-basis [db] protein), ingredient blends were prepared with 0, 17.5, 20, 22.5, 25, and 27.5% distiller’s dried grains with solubles (DDGS) and other ingredients (soybean meal, corn, fish meal, whey, soybean oil, vitamin and mineral mix). The blends were moisture balanced to 15% db, then extruded in a twin screw extruder using a 2 mm die at 190 rpm, and a 3 mm die at 348 rpm. Analyses of the extrudates included moisture content, expansion ratio, unit density, bulk density, sinking velocity, color (L*, a*, and b*), water absorption, water solubility, and pellet durability …

Threadfin Shad Impacts Phytoplankton And Zooplankton Community Structures In Channel Catfish Ponds, Bartholomew W. Green, Peter Perschbacher, Gerald Ludwig, Sara E. Duke

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Plankton community structure and chlorophyll a concentration were compared in 12 0.1-ha earthen ponds co-stocked with channel catfish (Ictalurus punctatus Rafinesque, 1818) in multiple-batch culture (initial biomass = 5,458 kg ha^-1) and a planktivore, threadfin shad (Dorosoma petenense Güther, 1867; initial biomass = 449 kg ha^-1), during the April-November growing season. We used a completely randomized design in 2 x 2 factorial arrangement to test planktivore level (presence or absence of threadfin shad) and channel catfish feeding frequency (daily or every 3^rd d). Channel catfish were fed a 32% protein feed to apparent …

Validation Of Live Animal Ultrasonic Measurements Of Body Composition In Market Lambs, J. C. Emenheiser, S. P. Greiner, Ronald M. Lewis, D. R. Notter

Department of Animal Science: Faculty Publications

Market lambs from the state fair of Virginia (n = 172) were ultrasonically evaluated by 4 scan technicians and 3 image interpreters to determine accuracy of ultrasonic estimates of loin muscle area (ULMA), backfat thickness (UBF), and body wall thickness (UBW). Lambs were initially scanned at the preferred magnification setting of each technician; 2 chose 1.5× and 2 chose 2.0×. Lambs were then scanned a second time for ULMA and UBF with machine magnification settings changed from 1.5 to 2.0×, or vice versa, midway through the second scan. Lambs were then slaughtered, and analogous measurements [carcass loin muscle area, …

Dairy Animal Care: Quality Assurance

Nebraska Beef Quality Assurance Program

Dairy producers are encouraged to participate in the voluntary Dairy Animal Care and Quality Assurance (DACQA) Certification program. The purpose of this program is to enhance and demonstrate quality animal care practices, which assure food safety, quality and value as well as enhance consumer confidence in the milk and beef products that are harvested from cattle on America’s dairy farms.

Evaluation Of Frontline Demonstration Of Greengram (Vigna Radiata L.) In Sundarbans, West Bengal, Ganesh Chandra

Ganesh Chandra

Green gram (mungbean) is one of the important pulse crop in India, which plays a major role in augmenting the income of small and marginal farmers of Sundarban. The prevalent farming situation in Sundarban areas being characterised by kharif season with paddy cultivation in rain-fed condition and water requirement for growing rabi and summer crops are met only through residual soil moisture and/or stored rain-water. The low production of traditional varieties of greengram was a cause of concern for the farmers at large. To overcome this problem of low yield, Krishi Vigyan Kendra of CIFRI has conducted frontline demonstration field …

Effects Of Vermicomposting Duration To Macronutrient Elements And Heavy Metals Concentrations In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

Vermicomposting using Lumbricus rubellus was conducted in two different durations, 10 and 30 weeks in the same plots. Three different of treatments combination were prepared with eight replicates for each treatment namely cow dung : kitchen waste in 30:70 ratio (T1), cow dung : coffee grounds in 30:70 ratio (T2), and cow dung : kitchen waste : coffee grounds in 30:35:35 ratio (T3). Macronutrients elements in the vermicompost from each treatment were measured in the tenth and thirtieth week. Comparatively longer duration of vermicomposting by using Lumbricus rubellus enhanced the quality of vermicompost by the increase of the macronutrient elements …

Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell

Bulletins 4000 -

Potassium plays a major role in plant growth. It maintains the solutions in plant cells at ionic strengths suitable for maintaining strong plant walls and for the proper functioning of leaf pores (stomata) and plant processes such as photosynthesis, transport of sugars and enzyme activation.

Potassium does not become a direct part of the plant structure but acts to regulate water balances, nutrient and sugar movement in plant tissue. Plants deficient in potassium cannot use other nutrients and water efficiently. They are less tolerant of stresses such as drought and waterlogging and are more susceptible to pests and diseases.
