Using Dietary Additives to Manipulate Rumen Fermentation and Improve Nutrient Utilization and Animal Performance
The rumen is arguably the most important organ in the ruminant digestive system. Ruminal microbial protein and volatile fatty acid (VFA) synthesis supply most of the protein and energy needs of the ruminant. Rumen function problems can reduce intake, digestion, and health of ruminants and culminate in death. Furthermore, inefficient rumen function reduces animal performance and health and contr...
متن کاملRumen Microbiome from Steers Differing in Feed Efficiency
The cattle rumen has a diverse microbial ecosystem that is essential for the host to digest plant material. Extremes in body weight (BW) gain in mice and humans have been associated with different intestinal microbial populations. The objective of this study was to characterize the microbiome of the cattle rumen among steers differing in feed efficiency. Two contemporary groups of steers (n=148...
متن کاملFeed additives.
Feed additives used to supplement dairy rations can increase daily feed cost from 2 to 65 per animal. The economic response (benefit to cost ratio) varies from $2.00 to $12.00 for each dollar invested in a specific additive. Knowledgeable dairy veterinarians must understand the role of each additive, when it will be beneficial, inclusion level, strategies and limitations associated with an addi...
متن کاملNonruminant Nutrition: Feed Additives
A total of 150 weanling pigs [(Landrace × Yorkshire) × Duroc, BW = 6.76 ± 0.61 kg] were used in a 42-d trial to investigate the effects of dietary Aviplus-S supplementation on growth performance, fecal score, fecal moisture, fecal pH, and blood profiles. Pigs were randomly assigned to 1 of 5 treatments according to BW. Dietary treatments were NC, basal diet (without antibiotics); PC, NC + 39 mg...
متن کاملRuminant Nutrition: Feed Additives
Feed additives are largely used in beef cattle diets to improve performance and reduce risks of nutritional disorder diseases like acidosis and timpanism. However, some countries tend to ban the use of ionophore in animal nutrition due to the risk of resistance of some microorganisms. Therefore, alternatives to non-antibiotic additives must be studied. The objective of this work was to investig...
