New natural feed additives: efficiency in pork production

Use of 'natural' products as alternatives to antibiotic feed additives in ruminant production.

The banning in 2006 of the use of antibiotics as animal growth promoters in the European Union has increased demand from producers for alternative feed additives that can be used to improve animal production. This review gives an overview of the most common non-antibiotic feed additives already being used or that could potentially be used in ruminant nutrition. Probiotics, dicarboxylic acids, e...

Feed 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...

Nonruminant 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...

Ruminant 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...
