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.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanisms behind the metabolic changes observed when transition cows are administered monensin, as well as the effects of supplementing mid-lactation cows with two commercial amino acid products were investigated. Traditionally, the effects of monensin are attributed to increased gluconeogenic precursor supply, but recent research indicated that the effects of monensin extend beyond gluconeogenic flux. Thus, the primary objectives of Experiment 1 were to determine if monensin modulates transition cow feeding behavior, ruminal pH, and/or expression of key metabolic genes. Overall, monensin decreased time between meals prepartum (126 vs. 143 ± 5.0 min; P
Download or read book Nutritional Strategies of Animal Feed Additives written by Abdel-Fattah Z. M. Salem and published by NOVA. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality of feed nutrition is influenced not only by the content but also by some other aspects such as, feed presentation, hygiene, anti-nutritional factors, digestibility and palatability. Feed additives provide a mechanism by which such dietary deficiencies can be addressed and also benefits not only associated with the nutrition and thus the growth rate of the animal concerned, but also its health and welfare. Feed additives could modify animal metabolism in specific and direct ways by improving production efficiency (weight gain or milk yield); improving carcass composition in growing animals; increasing milk yield in lactating animals; and decreasing animal waste per production unit. This book discusses the impacts of feed additives on animal metabolism, health and production.

This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidly growing human population has increased the dependence on fossil fuel based agrochemicals such as fertilizers and pesticides to produce the required agricultural and forestry products. This has exerted a great pressure on the non renewable fossil fuel resources, which cannot last indefinitely. Besides, indiscriminate use ofpesticides for pests (weeds, insects, nematodes, pathogens) control has resulted in serious ecological and environmental problems viz. , (A) Increasing incidence of resistance in pest organisms to important pesticides. (B) Shift in pests population, particulary in weeds and insects. In weeds, species that are more closely related to the crops they infest have developed. In insects, scenario is most grim, the predators have been killed and minor insect pests have become major pests and require very heavy doses ofhighly toxic insecticides for their control. (C) Greater environmental pollution and health hazards (a) particularly from contamination of surface and underground drinking water resources and (b) from their inhalation during handling and application. (D) Toxic residues of pesticides pollute the environment and may prove hazardous to even our future generations. (E) Some agricultural commodities may contain minute quantities ofpesticides residues, with long tenn adverse effects on human and livestock health. Therefore, serious ecological questions about the reliance on pesticides for pests control has been raised. The use of fertilizers, besides causing environmental problems has also impoverished the soil health and decreased the beneficial soil fauna. For example, in some major crop rotations viz.

Available in PDF, EPUB and Kindle. Book excerpt: Animal husbandry is strongly influenced by weather and climate. Climate change/variability imposes multiple stresses in animals and thus vital to understand the impact of environmental stress on livestock production and reproduction. Among the environmental variables affecting livestock, heat stress seems to be one of the more intriguing factors making difficult animal reproduction and production. Information and knowledge on animal responses to the environment continues to be in process, managing livestock to reduce the impact of adverse weather and climate remains a challenge. Responding to the challenges of global warming necessitate a paradigm shift in the practice of agriculture and in the role of livestock within the farming system. The key thematic issues on environment stress and livestock production includes: early warning system, multiple stress research, exploitation of genetic potential of native breeds, suitable breeding programme and nutritional intervention research. Livestock farmers should have key roles in determining what adaptation and mitigation strategies they support if these have to sustain livestock production in changing climate. The integration of new technologies into the research and technology transfer systems potentially offers many opportunities to further the development of climate change adaptation strategies. This publication is therefore a multi-authored attempt to present the scientific fraternity high quality resource material in the field of climate change and livestock production. Attempts were made to discuss the adaptive mechanism that the animal exhibits to counteract the adverse effects of heat stress. In addition to the adaptive mechanisms, several management and feeding practices have also been established as tested methods for reduction of stress effects in livestock. It also highlights the challenges the livestock industry faces in maintaining the delicate balance between animal welfare and production. This book is a comprehensive resource for the researchers, teachers and students to understand stress, stress management and livestock productivity so as to sustain animal production in the Country under projected climate change scenario.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Aspects of Housing for Animal Production is concerned with environmental aspects of housing farm animals. The discussions are organized around physical and physiological principles; environmental influences on reproduction; environmental influences on the productivity of farm animals; optimal housing environments for temperate and cool climates; housing environments for hot climates; engineering and control of the house environment; and the constraints of welfare and disease. This text consists of 32 chapters divided into nine sections. The first chapter explores the physiological mechanisms whereby the food- or fiber-producing animals maintain a constant body temperature under climatic extremes and the possible impact that these physiological processes may have on productive systems. This discussion is followed by chapters on the influence of climate on the decision to house livestock; the effect of the environment on animal reproduction; thermal influences on poultry; and the importance of ventilation and temperature control. This text also considers the poultry housing problems in tropical and subtropical climates; insulation of animal houses; and the interaction between feathering and egg production in laying hens. This book will appeal to those working in the field of housing for animal production, both in research and development and at a practical level.
