    University of Adelaide at Midwest Meeting


    Ashlee McEvoy ASAP/ASAS 2017 Communications Intern

    The University of Adelaide, Roseworthy campus was mentioned a couple of times during the American Dairy Science Association and American Society of Animal Science Midwest meeting this month in Omaha, Nebraska, United States of America.

    Two students presented oral presentations, “Piglet creching decreases protein content in colostrum” presented by Yanisse Montano, and “Influence of seminal additives on sow fertility” presented Tivon Brown.

    The first presentation by Montano involved observing the amount of colostrum that in newborn piglets intake in the first 24 hours of life before gut epithelial closure takes place. Montano first discussed how it has previously been hypothesised that the order of farrowing may have an effect on suckling, meaning that the first-born piglets were more likely to ingest more colostrum than those later born. The objective of the study was to assess if creching, the process of placing piglets into a warm box at birth to prevent suckling, before returning all piglets to the sow at the end of the farrowing process, increased the total plasma protein levels at 24 hours post farrowing in the final 3 piglets born in each litter. It was also investigated if this increase was associated with higher milk protein synthesis in the mammary gland. This study was completed at the University of Adelaide at the Roseworthy piggery facilities. A total of 28 litters were withheld from suckling for 4 hours after first piglet, and 28 litters were allowed to immediately. Blood was collected at 24 hours post farrowing in the first and then last three piglets of each litter and colostrum samples were taken from the front, middle and rear glands of all sows immediately after birth of first piglet, and again 3 hours after.
    The findings of this study showed that the total plasma protein levels at 24 hours did not differ in the piglets born first and last, but the total plasma protein levels were significantly higher in the piglets that were not creched. There was also no differences in total protein content in colostrum when sampled immediately after farrowing, however it tended to decrease in sows with creched litters than the control sows.

    Chromium supplementation shows potential for heat stress management in pigs


    By Penny Young, ASAS/ASAP Intern

    New research from the University of Melbourne and accepted for publication in Translational Animal Science finds that chromium supplementation may help to increase insulin sensitivity, normalize NEFA metabolism and reduce heat stress in pigs.

    Managing heat stress in animals is important from both economic and welfare perspectives, and the findings from this study make a case for the inclusion of dietary chromium in diets during periods where heat stress is anticipated.

    The team, headed by Fan Liu and sponsored in part by Australian Department of Agriculture and Water Resources via the Carbon Farming Futures Program, investigated several markers of heat stress in pigs and also looked into the effects of chromium supplementation on these indicators. Insulin sensitivity was a particular focus because research has suggested that increased insulin sensitivity may help to alleviate heat stress.

    Is it worth selecting for high milk production in beef cattle?


     

    Penny Young, ASAS/ASAP Intern

    Milking ability is a trait that many producers select for in their production systems, with the belief that it is one of the most significant influences on the weaning weight of a calf. However, a study by Edwards et al. from the University of Tennessee, recently published in Translational Animal Science has found that when beef cattle are raised in an environment where feed is highly available, greater milk production in the mother does not translate to improved weaning weight. In fact, all things considered, selecting for high milk production appears to have negative outcomes for reproductive efficiency.

    The study aimed to investigate the effect of milk yield on a variety of markers, such as reproductive and calf performance, cow bodyweight, and circulating blood metabolites. The team collected data from 237 Angus-sired beef cows on three research stations in Tennessee; recording 24hr milk production on two dates post partum, as well as collecting samples of milk for analysis. The cows’ body weight and body condition score were collected weekly throughout breeding, and the calves’ bodyweights were recorded at birth, mid-weight (day 58) and at weaning.

    Yeast pro- and paraprobiotics can bind pathogenic bacteria: potential for prophylaxis and treatment


    Penny Young, ASAS/ASAP Intern

    As we face the challenge of managing growing antibiotic resistance in pathogens, efforts to find antibiotic alternatives are redoubled.

    An area that shows particular promise is the use of probiotics, both prophylactically and as a treatment measure. Research recently published in Translational Animal Science finds that yeast pro- and paraprobiotics are able to bind pathogenic bacteria that can cause disease in animals, such as Salmonella and Listeria species.

    Other studies have found that probiotics and paraprobiotics have many modes of action. They can bind directly to pathogens, which helps to protect the animal by reducing the binding of pathogen to host intestinal cells and also facilitates removal of the pathogen from the host. The action of the yeast probiotics can take the form of a variety of mechanisms, with some involving direct antagonism or competitive inhibition that prevents colonization of the mucosal surface of the intestine. Some pathogenic bacteria produce toxins, and in some cases the yeast can protect the host by directly binding to these toxins. The yeast probiotics also may help to stimulate the host immune system, engaging a more effective response and thus improving outcomes.

    Meat Standards Australia


    Ashlee McEvoy ASAS/ASAP 2017 Communications Intern 24th March 2017.

    The Australian red meat industry developed Meat Standards Australia (MSA), and opened up to the beef industry in 1998. This purpose of this program became ensuring that any beef product is to reach consumer expectations. The MSA index that is used to measure these consumer expectations are based on almost 700,000 consumer taste tests by more than 100,000 consumers from nine countries.

    For beef to be eligible for MSA grading, the cattle must be from an MSA registered property. The grading of beef can only be assessed by an MSA-accredited grader at any of the 43 MSA-licensed beef processing plants that are currently in Australia.

    The graders job is to assess traits that have been scientifically proven to affect the eating quality of a carcass. These traits include ossification, marbling, pH, subcutaneous rib fat thickness, hump height, sex and hot standard carcass weight. Factors such as hormonal growth promotant status, milk-fed vealer category, tropical breed content and saleyard status are declared by the producers and again verified by the processing plant.

    Queensland wild dog fences


    Ashlee McEvoy ASAS/ASAP 2017 Communications Intern 25th March 2017

    Remote Area Planning and Development Board (RAPAD) was allocated funds from the State Government’s $5 million commitment in May 2016 for the Queensland Feral Pest Initiative.

    The first round of funding towards the RAPAD fencing scheme in central west Queensland was given out in July 2016. In the second round, released this month, seven clusters made up of 31 producers are now expected to erect close to 800 kilometers of wild dog proof fencing. This second round is expected to protect almost 400,000 hectares, and projects to double the sheep numbers in that area. This second wave was only available to those who did not receive first round funds.

    Grad students recap Southern Section events


    By Brittni Littlejohn, Sierra Lockwood, and Sam Ingram

    The American Society of Animal Science – Southern Section hosted its 2017 meeting last month in Franklin, TN. During the meeting, the Graduate Student Meet & Greet was held on February 5, followed by the Graduate Student Lunch & Learn on February 7. These events were implemented with the goal of providing a networking opportunity as well as a chance to gain insight on the successful transition to the professional world.

    The Graduate Student Meet & Greet was held during the first day of the conference to introduce participants to their fellow graduate students who they would be interacting with during the remainder of the conference. The informal setting provided participants a comfortable environment for networking and was very well received. Eight schools were represented during this event and included the following: Auburn University, Fort Valley State University, North Carolina State University, Texas A&M University, Texas A&M University – Kingsville, University of Arkansas, University of Tennessee, and Virginia Tech.

    The Graduate Student Lunch & Learn theme was “Fueling the Future.” During the event, students were randomly assigned to tables to encourage additional networking among fellow students. The first speaker was Dr. Rand Broadway from the USDA-ARS who presented on “How to make the most of your graduate career.” Dr. Broadway’s presentation included advice on how to choose a program and mentor, the importance of collaboration, and how to be proactive during a graduate program. Following Dr. Broadway’s presentation, Dr. Mike Moseley from Positively Mose, LLC and Zoetis (retired) presented on “How to make the transition from graduate student to industry professional.” During Dr. Moseley’s presentation, he discussed the following topics: taking ownership of your career, characteristics that make one employable, and how to prepare for an interview. Both presentations were well received by the graduate students in attendance and made the Lunch & Learn a great success! Nine schools were represented at the Lunch & Learn and included the following: Auburn University, North Carolina State University, Texas A&M University, Texas A&M University Commerce, Texas Tech University, University of Arkansas, University of Georgia, University of Tennessee, and Virginia Tech.

    2017 Annual Meeting preview: Forages and Pastures Symposium


    Plans are underway for a Forages and Pastures Symposium focusing on a whole-system approach to cover crops in livestock production. Save the date: Tuesday, July 11, 2017, 2:00-5:00 PM. Make plans to join us for this symposium at the 2017 ASAS-CSAS Annual Meeting & Trade Show!

    Cover crops present a unique opportunity in livestock production, with the potential to improve the health and productivity of the whole production system. They can improve soil health and water quality, and also provide a valuable source of food for livestock. Support for a whole-system approach to the use of cover crops has often largely been based on anecdotal evidence. This symposium, put together by the Forages and Pastures Committee, draws from research with long-term data providing insight into the broad range of benefits offered by including cover crops in livestock systems. This research is particularly important in the context of our rapidly growing global population, as production intensification becomes more significant and our production systems must be optimized, while ensuring that environmental health is managed.

    Clayton Robins, chair of the Committee, explains that cover crops can play a key role in regenerative agriculture and also in helping to improve the resilience of production systems. This will be vital moving into the future.

    The presentations making up this symposium offer economic and realistic assessments of the role of cover crops and of the benefits and practical implications of including them in a system. Many aspects of cover crops will be addressed; from their potential as economical forage sources and their impact on animal performance, to their influence on water and nutrients in the system. The speakers will present research based in both the Southern and Northern Great Plains of North America and also from Brazil, hence the challenges and benefits of including cover crops in significantly different environments will be examined. Their role in conservation and regeneration will also be discussed.
