• Intestinal health means general health

  Healthy animals have optimal live performance and little need for veterinary interventions. As a consequence, the aim of animal rearing is to maintain them as healthy as possible for the highest return of the investment. There are multiple approaches to reach this ambitious goal: the first tool is good nutrition. It is important to correctly balance the nutrients intake to meet animal requirements during each phase of their productive life.

• AviPlus®P to help chickens against kinky back syndrome

  Kinky back is scientifically defined as Bacterial Chondronecrosis with Osteomyelitis (BCO) and is a complex syndrome mostly affecting broilers with some episodes in turkeys as well. The syndrome manifests itself with symptoms like lameness, starting at 3 weeks of age and resulting in lowered feed intake, reduced weight gain, and up to 5-7% mortality.

• Stress affects intestinal health: feed additives can help

  We normally think of stress as psychophysical fatigue, but stress is medically defined as the functional response of an organism to any kind of stimulus (stressor, that can be of any intensity and duration). Stressors can have different nature (microbial, toxic, thermal, traumatic, emotional) and alter the neurohormonal equilibrium of the organism, leading to an overproduction of cortisol, the “stress hormone”. During their life, reared animals are exposed to many stressors.

• The magic powder doesn’t exist

  During the rearing cycle, chickens can experience different health problems. For what concern bacterial infections, in the very first period of life, one of the most common causes of chicken illness and death is omphalitis, often due to E. coli infections.

• How can we transition from antibiotics growth promoters to feed additives?

  Since animals are reared in intensive conditions, antibiotics are needed to treat bacterial infections, but they are also very well known because of their effect on animal feed conversion, growth, and performance.

• The last chance for antibiotics as growth promoters

  Meat is increasingly consumed globally so that the farming industry is constantly improving animal production. In poultry, genetics and nutrition for broilers are continuously selected to answer this demand, improving animals’ performance and final weight.

• Development of a feed additive to reduce caecal Campylobacter jejuni in broilers at slaughter age: from in vitro to in vivo, a proof of concept

  Aim: In vitro and in vivo challenge studies were undertaken to develop an in-feed additive of microencapsulated propionic, sorbic acids and pure botanicals to control Campylobacter jejuni in broilers at slaughter age.

• Microencapsulated sorbic acid and nature-identical compounds reduced Salmonella Hadar and Salmonella Enteritidis colonization in experimentally infected chickens

  The reduction of Salmonella prevalence in broilers is a priority in European Union agricultural policies because treatment with antibiotics is forbidden by Regulation (EC) 2160/2003. Two trials were conducted to evaluate the efficacy of a microencapsulated blend of sorbic acid and nature-identical compounds (i.e., chemically synthesized botanicals; SAB) on the reduction of the cecal prevalence and contents of Salmonella enterica serovars Hadar and Enteritidis in experimentally infected chickens.

• AviPlus®P: a tool to improve antibiotics efficacy against resistant infections

  Poultry industry is facing many different pathologies that affect not only animal health but also their live performance. For example, C. perfringens (with coccidia as a predisposing factor) causes necrotic enteritis (NE), with billion dollars losses every year.

• AviPlus®P helps poultry to cope with kinky back syndrome

  Kinky back is a complex syndrome mostly affecting broilers with some episodes in turkeys as well, defined in medical terms as Bacterial Chondronecrosis with Osteomyelitis (BCO). The rapid growth of heavy birds during the first phase of life is often accompanied by an inadequate skeleton’s development.

• How to control necrotic enteritis with organic acids and botanicals

  Necrotic enteritis (NE) is a poultry intestinal disease caused by the proliferation of toxigenic strains of Clostridium perfringens (CP), with coccidia infections being the best-known predisposing factor. CP causes subclinical infections, with chronic damage and inflammation of the intestinal mucosa and significant loss in performance. The increase in NE in the poultry industry requires new strategies to improve the growth of the animals by supporting intestinal health in challenging conditions.

• In vitro anticoccidial activity of thymol, carvacrol, and saponins

  The anticoccidial activity of thymol, carvacrol, and saponins was assessed in an in vitro model of coccidiosis. Eimeria spp. sporozoites were collected from field samples, characterized, and used for 2 different invasion assays on Madin-Darby Bovine Kidney cells (MDBK).
