A Framework For Transparency In Precision Livestock Farming, Kevin C. Elliott, Ian Werkheiser

Philosophy Faculty Publications

Simple Summary

The emergence of precision livestock farming (PLF) raises important issues for many different social groups, including farmers, consumers, regulators, and the food industry. This paper explores how those who develop PLF systems can communicate more effectively with different groups about the technologies that they are creating. We suggest that developers reflect on four issues: (1) the different kinds of information that various groups might want to know; (2) the audiences that might care about these different kinds of information; (3) the major difficulties involved in providing the information; and (4) potential strategies for overcoming those difficulties.

Do Fishery Meeting Attendees Represent The Fishing Industries?, Dominique Seibert

LSU Master's Theses

Public meetings are a highly utilized tool for disseminating important or useful information. Many agencies rely on them to reach various stakeholders and community representation at these meetings is important. A substantial amount of research has been conducted on various aspects of public meetings including different techniques, factors impacting attendance, and representativeness, that is attendees’ opinions representing the opinions at-large. A noticeable gap in the research includes information on public fishery meetings, commercial fishing industries, and their members’ participation. With the U.S. commercial fishing industries supporting more than a million jobs and providing more than a 200-billion-dollar economic impact annually, …

Workshop Abstracts: The International Conference & Workshop On Lobster (And Crab) Biology And Management, Department Of Primary Industries And Regional Development, Western Australia, Western Rock Lobster Council, Fisheries Research And Development Corporation

International Conference on Lobster (and Crab) Biology and Management (ICWL)

The theme of the 12th ICWL is ‘ecosystem-based fisheries management (EBFM)’. EBFM is a holistic approach to fisheries management that recognises all the interactions within an ecosystem rather than considering a single species or issue in isolation. We consider this represents best practice for fisheries management and reflects that fisheries research and management focus is now broader than just sustainability. Therefore, in addition to presentations that focus on lobster (and crab) biology and stock assessment, we have also welcomed presentations that examine other aspects of EBFM, such as ecosystem effects of fishing, economic assessments, social issues, governance, and compliance with …

Population-Level Dna Study Of Stenotrema And Euchemotrema (Gastropoda: Polygyridae: Stenotrematini) Reveals Majority Of Species Are Poorly Circumscribed, Alexander C. Cooper, Elizabeth A. Bergey, Kathryn E. Perez

School of Integrative Biological & Chemical Sciences Faculty Publications

The North American land snail tribe Stenotrematini (Emberton, 1995) is composed of 40 taxa from the genera Stenotrema (Rafinesque, 1819) and Euchemotrema (Archer, 1939). We conducted the first thorough examination of this group since 1948 by sequencing 196 individuals representing 31 of 40 members of the tribe using a combination of cytochrome c oxidase subunit I (COI) and a portion of the 5.8S gene of the large ribosomal subunit (LSU) with the accompanying internal transcribed spacer (ITS-2) region. We reexamined the validity of this tribe by incorporating new sequences with previous DNA work on the …

Genomic Insights Into The Mystery Of Mouse Mummies On The Summits Of Atacama Volcanoes, Jay F. Storz, Schuyler Liphardt, Marcial Quiroga-Carmona, Naim M. Bautista, Juan C. Opazo, Guillermo D’Elía, Jeffrey M. Good

Jay F. Storz Publications

Our understanding of the limits of animal life is continually revised by scientific exploration of extreme environments. Here we report the discovery of mummified cadavers of leaf-eared mice, Phyllotis vaccarum, from the summits of three different Andean volcanoes at elevations 6,029–6,233 m above sea level in the Puna de Atacama in Chile and Argentina. Such extreme elevations were previously assumed to be completely uninhabitable by mammals. In combination with a live-captured specimen of the same species from the nearby summit of Volcán Llullaillaco (6,739 m),¹ the summit mummies represent the highest altitude physical records of mammals in the …

Identification Of Lipids And Cytokines In Plasma And Follicular Fluid Before And After Follicle-Stimulating Hormone Stimulation As Potential Markers For Follicular Maturation In Cattle, Alexandria P. Snider, Renata S. Gomes, Adam F. Summers, Sarah C. Tenley, Mohamed A. Abedal-Majed, Renee M. Mcfee, Jennifer R. Wood, John S. Davis, Andrea S. Cupp

Department of Animal Science: Faculty Publications

The process of follicle maturation leading to ovulation is a key milestone in female fertility. It is known that circulating lipids and cytokines play a role in the follicle’s ability to go through follicular maturation and the ovulatory processes. However, the specific mechanisms are not well understood. We posit that dysregulation of granulosa cells influences the ovarian environment, which tries to adapt by changing released lipids and cytokines to achieve follicular maturation. Eleven non-lactating adult females underwent estrus synchronization with two injections of PGF2 14 days apart. Daily blood samples were collected for 28 days to monitor steroid hormone production …

Why Humans Kill Animals And Why We Cannot Avoid It, Benjamin L. Allen, Christopher Bobier, Stuart J. Dawson, Peter J S Fleming, Jordan Hampton, David Jachowski, Graham I H Kerley, John D. Linnell, Kelly Marnewick, Liaan Minnie, Mike Muthersbaugh, M Justin O'Riain, Dan Parker, Gilbert Proulx, Michael J. Somers, Keifer Titus

Animal production and livestock research articles

Killing animals has been a ubiquitous human behaviour throughout history, yet it is becoming increasingly controversial and criticised in some parts of contemporary human society. Here we review 10 primary reasons why humans kill animals, discuss the necessity (or not) of these forms of killing, and describe the global ecological context for human killing of animals. Humans historically and currently kill animals either directly or indirectly for the following reasons: (1) wild harvest or food acquisition, (2) human health and safety, (3) agriculture and aquaculture, (4) urbanisation and industrialisation, (5) invasive, overabundant or nuisance wildlife control, (6) threatened species conservation …

Turkish Journal of Veterinary & Animal Sciences

Boron is a required trace element for plants, humans, and animals and it has significant influence over biological functions and the immune system. Vaccines have aided humans in the control of many contagious diseases around the world. The success of global immunization campaigns may be possible with the development of effective and low-cost vaccines and adjuvants. For this reason, the present study aimed to determine the adjuvant activity of easily accessible boron compounds. In this study, six different vaccines were prepared, including inactive Staphylococcus aureus bacteria, boric acid, aluminum hydroxide, montanide ISA 50, and ISA 206, ISA 50 + boric …

Effect Of Exogenous Melatonin On Metabolic Profile And Reproductive Performance In Undernourished Suckling Merino Ewes In The Early Postpartum Period, Bariş Güner, Buse Öztürk, Aslihan Ayalp, İhsan Kisadere, Nevzat Saat, Muhi̇tti̇n Zengi̇n, Recai̇ Kulaksiz, Şükrü Meti̇n Pancarci

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine whether serum metabolite and hormones of ewes with low body condition scores subjected to the melatonin plus progesterone-based protocol (MPE) would be similar to a single progesterone-based protocol (PE) and whether melatonin ear implant supplementation could increase pregnancy rate. Ninety suckled Merino ewes with singleton lamb were equally allocated in two experimental groups (MPE, PE) and a control group (CON) on days 53 ± 3 (D0) postpartum. Ewes in MPE group were subjected to exogenous melatonin plus progesterone-based protocol [Melatonin (day 0) + P4 insertion (day 35) + 500 IU eCG (day 42)]. Ewes in …

Radiographic Pelvimetry In Scottish Fold Cats: Sex-Related Differences, Osman Yilmaz, Davut Koca, Talha Avcilar

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to obtain osteometric measurements of the pelvis of Scottish Fold cats using X-ray images and reveal the biometric differences of these measurement values in terms of sexual dimorphism. Radiographic images of the pelvis in the laterolateral and ventrodorsal direction were used in male and female Scottish Fold cats aged 2-4 years with dystocia and eutocia. The measurements of 18 osteometric parameters and 36 parameters, such as the height/width ratio of the cat pelvis, were taken, and statistical analysis of the measurements was initiated. When the pelvimetric data were examined, it was observed that all of …

Comparison Of Carcass Characteristics, Meat Quality, And Fatty Acid Composition In Slowand Fast-Growing Broilers At Different Slaughter Weights, Büşra Yaranoğlu, Hi̇lal Çapar Akyüz, Esi̇n Ebru Onbaşilar

Turkish Journal of Veterinary & Animal Sciences

This study aimed to compare the slaughter, meat quality characteristics, and fatty acid composition of fast-growing (FAG) and slow-growing (SWG) broilers at different slaughter weights. In the experiments, a total of 90 carcasses were used: 45 SWG (Hubbard-Isa Red JA) and 45 FAG broilers (Ross 308) with 15 carcasses from each slaughter weight group (1500 ± 50 g, 2000 ± 50 g, 2500 ± 50 g). Hot carcass yield and cold carcass yield detected in the FAG broilers were higher than in SGW broilers (p < 0.001). As the weight of slaughter increased, hot carcass and cold carcass yield increased (p < 0.001). The breast percentage was significantly lower in the SWG broilers compared to the FAG broilers (p < 0.001). In contrast, thigh, wing, and abdominal fat percentages were higher in the SWG broilers (p < 0.001). The breast percentage increased as the slaughter weight increased (p < 0.001). SWG broilers had significantly lower pH, except for the pH 24 of the thigh meat (p < 0.01). The L*, a*, and b* values of the SWG broilers were lower than the FAG broilers (p < 0.01). In terms of a* values determined initially and at the 24th h in the breast and thigh meat, the 1500 g slaughter weight group had by far the highest value (p < 0.01). SWG broilers had significantly lower values in terms of cooking loss, water-holding capacity, and drip loss (p < 0.001). C18:2ω6 was detected at higher amounts in the FAG broilers (p < 0.05). The FAG broilers had higher PUFA, desired fatty acids, PUFA/SFA, and thrombogenic index values (p < 0.05). The results show that FAG broilers can meet the strong worldwide demand for meat quantity and quality. Slaughter weight changes only affected the quantity of the meat.
