Threadfin Shad Impacts Phytoplankton And Zooplankton Community Structures In Channel Catfish Ponds, Bartholomew W. Green, Peter Perschbacher, Gerald Ludwig, Sara E. Duke
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 3rd d). Channel catfish were fed a 32% protein feed to apparent …

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
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.
