Book excerpt: The goal of this dissertation was to improve the understanding of mechanisms behind the positive effects on milk production and health of rumen-protected choline (RPC) supplementation during the transition to lactation period and interrogate whether choline could benefit cattle in other stressful life stages. The objectives of the experiment presented in Chapter II were to 1) determine the impact of increasing dose of prepartum RPC supplementation on milk production and blood biomarkers in multiparous Holstein cows; 2) determine if there are continuous responses across a range of actual prepartum choline ion intakes. There was no benefit to milk production of increasing the prepartum dose of RPC, nor did milk production respond along a continuous range of prepartum choline ion intakes. There was a benefit of supplementing RPC at the current recommended dose (15 g choline ion/d) on energy corrected milk yield, consistent with previous research. This chapter also presented evidence that peripartum RPC supplementation may influence nutrient partitioning through altered insulin function and may improve gastrointestinal function. Chapter III presented the effects of maternal choline supplementation on early life performance of offspring. The objectives of the experiment presented were to 1) determine if increasing dose of late gestation RPC, supplemented to multiparous Holstein cows, would improve growth in calves; and 2) determine if in utero choline exposure alters DNA methylation patterns. In utero choline exposure improved the rate of growth and feed efficiency in female Holstein and male Holstein x Angus calves, while improving only feed efficiency in female Holstein x Angus calves. Consistent with results in adult cows presented in Chapter II, in utero choline exposure may have improved gastrointestinal function in Holstein calves. In utero choline exposure altered global DNA methylation patterns in male Holstein x Angus calves, representing a potential mechanism to explain phenotypic responses. Chapter IV interrogated the effects of supplementing RPC to multiparous Holstein cows under experimental heat stress. The objectives of this experiment were to 1) determine if supplementing RPC to heat stressed cows would improve milk production and 2) determine if supplementation was required prior to and during, or just during the heat stress insult, i.e., supplementation strategy. Either RPC supplementation strategy reduced the respiration response to heat stress compared to CTL. Supplementing RPC before and during heat stress improved milk production prior to and during heat stress while supplementation only during heat stress had no effect on milk yield. Supplementing RPC has the potential to improve performance of cattle in dairy production systems beyond the transition to lactation period. The potential for choline to impact gastrointestinal function should be further interrogated as a mechanism to explain the positive effects on performance.

Download or read book Effects of an Extruded Flaxseed Supplement on Transition Cow Immune Function and Effects of a Methane Inhibitor on Transition Cow Ovarian Activity written by Molly Fetter and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In cattle, the transition period, which encompasses three weeks prior to three weeks after calving, is a critical time in the cows life with increased incidence of metabolic and infectious diseases. During this time cows suffer from immunosuppression and negative energy balance. Negative energy balance (NEB) and immunosuppression are related in transition dairy cows and occur due to extreme metabolic stress and changing hormones as the cow transitions from a pregnant to energy-demanding lactating state coupled with decreased dry matter intake. Incidences of periparturient diseases are not only detrimental to the overall health and well-being of the cow, but they can also decrease milk output and reproductive efficiency, causing economic loss to the producer. For these reasons, improved management during the transition period that improves the health and well-being of the cow are paramount for setting the stage for successful reproduction and high milk production.Two approaches were taken to address the challenges of the transition period. The first approach was to feed an omega-3 fatty acid extruded flaxseed supplement and measure effects on transition dairy cow immune function, plasma metabolites, and fatty acid composition of milk fat, plasma, and red blood cells. Polyunsaturated fatty acids (PUFA) decrease expression of pro-inflammatory cytokines promoting an anti-inflammatory state. Further benefits of feeding fats include improved milk production and composition and improved fertility.The second approach was to supplement transition dairy cows with a small molecule methane inhibitor and observe effects on return of ovarian activity. In a recent study, cows that received a methane inhibitor had increased body weight gain compared to cows that received a placebo. It is hypothesized that reducing methane production could make more energy available to the cow for other productive functions. To test this hypothesis, progesterone was measured in defatted milk via enzyme-linked immunoassay (ELISA). Parameters measured were days to evidence of a first corpus luteum (CL), length of first luteal phase, days to evidence of second CL, and interval between luteal phases. Evidence suggests that ovarian activity cannot resume until negative energy balance ceases and cows enter a positive energy balance. Cows that enter positive energy balance and cycle more before first service are more likely to have higher conception and pregnancy rates.These two approaches were taken because NEB and immunosuppression are the primary causes of negative health events in transition dairy cows. Overall, the first approach showed cows receiving the flaxseed supplement had greater ALA in plasma and milk fat, reduced mRNA abundance of TNF and IL6, and reduced neutrophil phagocytosis and ROS. Results indicate that the omega-3 supplement altered the activation status of the immune system and reduced inflammatory responses. This reduction in neutrophil activity may increase energy available to the cow for productive functions, although this speculation needs to be confirmed with further research. The milk fat and plasma exhibited greater ALA the longer the cows were on the diet indicating this supplement can be used to produce milk with higher omega-3 fatty acids, which is an area of increased consumer interest. In the methane inhibitor study, there were no differences observed between treatment groups for any of the reproductive parameters. Results from both studies provide further support for the importance of maintaining proper energy balance during the transition period to support immune function and productive functions in dairy cattle.

Book excerpt: Radioisotopes are used worldwide in a range of medical, industrial, research and academic applications. A large proportion of these radioisotopes are produced in particle accelerators, and the number of institutions that operate linear accelerators or cyclotrons and manufacture and distribute radiopharmaceuticals, for example, is significant and increasing. The production of radioisotopes using particle accelerators poses significant radiation hazards to workers, members of the public, and the environment when accelerators are operated without adequate radiation safety measures. This Safety Guide provides practical guidance for implementing radiation protection and safety measures in such facilities involved in the production and use of radioisotopes.
