Antioxidants in Animal Feed

This includes 17 original research articles and focuses on the knowledge on the effects of dietary antioxidants on host health and performance of production animals, including livestock, poultry and fish. It provides various nutritional approaches to improve antioxidant capacity and benefit host health in animal production. Production animals exposed to air pollution, heavy metals, or other stressful conditions can experience oxidative stress that may suppress animal health, performance, and production, subsequently impacting economic feasibility; hence, maintaining and improving oxidative status, especially through an appropriate nutrition strategy, are essential for normal physiological processes in animals. Promising research results have revealed that the administration of natural or synthetic antioxidants in an animal’s diet may be an important strategy to mitigate the negative influence induced by oxidative stress conditions. The Special Issue has been conceived to set out the knowledge on the effects of dietary antioxidants on host health and performance of production animals. It provides various nutritional approaches, mainly including vitamins, plant extracts, trace elements, non-essential amino acids, etc., to improve antioxidant capacity and benefit host health in livestock, poultry and fish. This book will encourage more scientists to move forward on the path to increasing knowledge on the effect of natural or synthetic antioxidants on the growth and health of production animals

Natural Additives in Food

In the search for a healthier diet and facing the uncertainties about the consumption of artificial additives, the scientific community has explored in the last years the potential of natural compounds, such as polyphenols, carotenoids, chlorophylls, essential oils, tocopherols, vitamins, polysaccharides, among others, obtained from the most diverse sources, such as plants and fungi, for the replacement of the artificial additives in food, which has made these compounds recognized as “natural additives”. In addition to being considered less harmful to health, and giving a certain functional property to a foodstuff, natural additives can also provide a beneficial synergistic effect in the food matrix. For the consumers, diverse studies have been showed that regular ingestion of bioactive compounds, that can be applied as natural additives, can be helpful for the prevention/treatment of several chronic and aging illnesses, such as cardiovascular diseases and neurological disorders. However, there is much to be researched on the viable use of bioactive compounds and to overcome their chemical limitations so that it can actually be used as natural additives in foods. This book addresses, through 18 scientific articles, some natural compounds with potential for use as preservatives, nutritional additives, coloring agents, flavorings, and various agents

Evaluation of the ingestive behaviour of the dairy cow under two systems of rotation with slope

The ingestive behaviour of grazing animals is modulated by the vegetation characteristics, topography and the type of stocking method. This research was carried out in 2019, at the Rumipamba CADER-UCE. It aimed to evaluate the impact of two contrasting stocking methods of dairy cows grazing a pasture with an average of slope >8.5%. Four dairy cows were set to graze a 0.4 ha paddock for 5 days for continuous stocking methods, while for the electric fence methods the dairy cows were restricted to 0.2 ha and the fence was moved uphill every 3 hours, repeating this process four times a day. Cow were equipped with activity sensors for 12 h per day. The whole procedure was repeated 2 times after realizing an equalization cuts and both paddocks, a rest time of 30 days and a random reassignment of paddocks to one of the treatments. The cows showed a difference in terms of the percentage of grazing P=0.0072, being higher with the electric fence (55% of the measurement time). From rising-plate-meter estimates of available biomass along the grazing periods, we calculated despite similar forage allowances (electric fence = 48.06 kg DM/cow/d and continuous = 48.21 DM/cow/d) a higher forage intake was obtained in the electric fence treatment (17.5 kg DM/cow/d) compared the continuous stocking (15.7 kg DM/cow/d) (P=0.006). In terms of milk production animals grazing under the differences electrical fence stocking method tended (P=0.0985) to produce more milk (17.39 kg/d) than those grazing in the continuous system (15.16 kg/d) due to the influence of the slope (P=0.05), while for milk quality the protein content was higher for the electric fence (33.7 g/l) than the continuous method (30.5 g/l) (P=0.039). None of the other milk properties differed between methods (P>0.05)
