Genetic parameters of longevity in crossbred mule ewes, and genetic relationships among longevity, growth, body composition, and subjectively assessed traits on mule lambs and ewes have been estimated using Bayesian linear censored models. Additionally, the genetic associations between longevity and culling reasons were examined. Data comprised 1,797 observations of mule ewes for longevity, culling reasons, growth, body composition, mouth scores, and type traits. Longevity was defined as the time (in years) from 2 yr of age (the age at first lambing of most ewes) to culling or death. Censored data (i.e., observations for which only the lower bound of the …
Feedyard Assessment: Assessor's Guide
Feedyard Assessment: Assessor's Guide
Nebraska Beef Quality Assurance Program
The BQA Feedyard Assessment is an on-site educational tool that allows for assessing and benchmarking key indicators of animal care and well-being as well as feedyard conditions. The Feedyard Assessment focuses on three main areas – Animals, Records and Best Management Practices (BMP), and Facilities and Equipment.
Stocker And Backgrounding Self Assessment
Stocker And Backgrounding Self Assessment
Nebraska Beef Quality Assurance Program
Cattlemen in stocker operations have long recognized the need to properly care for livestock. Sound animal husbandry practices, based on decades of practical experience and research, are known to impact the well-being of stocker cattle, individual animal health and herd productivity. Stocker cattle operations are located in many diverse environments and geographic locations in the United States. A universal set of production practices can not be recommended for all stocker cattle producers in light of the divergent climate and geographic variations of the stocker and backgrounding segment. Personal experience, training and professional judgment can serve as a valuable resource for …

Free-ranging livestock are classically controlled by herders. Holding, moving, or gathering free-ranging cattle requires flexible husbandry practices for efficient and effective lowstress animal management. Behavioral theory and practical experience indicates cattle can be taught to respond to auditory cues. Preliminary research has demonstrated that cows can be gathered autonomously using recorded audio cues associated with manual gathering. However, efficient gathering requires movement in the proper direction. Therefore, we believe using audio cues administered from directional virtual fencing (DVF™) equipment can facilitate proper animal orientation and facilitate the gathering of animals with minimal human intervention. Results from applying directional audio cues …

We evaluated whether stocking threadfin shad Dorosoma petenense as a forage fish in multiple-batch production ponds for channel catfish Ictalurus punctatus could substitute for formulated feed when channel catfish were fed daily or every 3 d. A completely randomized design in a 232 factorial arrangement was used for the experiment, which was conducted in twelve 0.1-ha earthen ponds. Prespawn adult threadfin shad were stocked at 404 kg/ha in six of the ponds, whereas the remaining ponds received no threadfin shad. Channel catfish stockers (0.35 kg/fish) were stocked at 5,040 kg/ha, and fingerlings (28.2 g/fish) were stocked at 14,820 fish/ha. Channel …
Antioxidant Activities Of Purple Rice Bran Extract And Its Effect On The Quality Of Low Nacl, Phosphate-Free Patties Made From Channel Catfish (Ictalurus Punctatus) Belly Flap Meat, Byungrok Min, Ming H. Chen, Bartholomew W. Green

Purple rice bran contains high amounts of natural antioxidants that consist of water- and lipid-soluble compounds. Hexane-insoluble and hexane-soluble fractions were separated from 100% methanolic extract from purple rice bran (RBE-HI and RBE-HS, respectively). Total anthocyanin, tannin, flavonoid, and phenolics contents were determined in those fractions, and their antioxidant capacities were evaluated by measuring 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical scavenging capability, oxygen radical absorbance capacity (ORAC), and iron chelating capability (ICC). RBE-HI and RBE-HSwere also added to restructured patties made fromminced channel catfish (Ictalurus punctatus) belly flap meat. Lipid oxidation, color, and/or textural properties were determined for raw and …
