• A microencapsulated feed additive containing organic acids, thymol, and vanillin increases in vitro functional activity of peripheral blood leukocytes from broiler chicks

  4 days of supplementation with a microencapsulated blend made up of citric and sorbic acids, thymol, and vanillin enhanced the in vitro PBL functions of degranulation, oxidative burst, and nitric oxide production compared with the control diet. Collectively, the data suggest feeding broiler chicks a diet supplemented with a microencapsulated blend of citric and sorbic acids, thymol, and vanillin may prime key immune cells making them more functionally efficient and acts as an immune-modulator to boost the inefficient and undeveloped immune system of young chicks.

• Dietary supplementation with a microencapsulated blend of organic acids and botanicals alters the kinome in the ileum and jejunum of Gallus gallus

  The objective of this project was to determine if feeding a microencapsulated product comprised of a blend of organic acids and botanicals (AviPlus®P) impacts the intestinal kinome of broiler chickens (Gallus gallus).

• Effects of microencapsulated blend of organic acids and essential oils as a feed additive on quality of chicken breast meat

  The present study aims to investigate the effect of dietary supplementation based on a blend of microencapsulated organic acids (sorbic and citric) and essential oils (thymol and vanillin) on chicken meat quality.

• Effects of a microencapsulated feed additive on growth performance and sanitary status of broiler chickens

  The aim of this study was to compare the growth performance and sanitary status of chickens receiving a control diet (CTR) and a feed containing a combination of citric acid, sorbic acid, thymol and vanillin microencapsulated (zootechnical additive 4d 3, EU Regulation No. 849/2012; AVIP).

• Modulation of the immune response to improve health and reduce foodborne pathogens in poultry

  Salmonella and Campylobacter are the two leading causes of bacterial-induced foodborne illness in the US. Food production animals including cattle, swine, and chickens are transmission sources for both pathogens. The number of Salmonella outbreaks attributed to poultry has decreased.

• Improved intestinal health leads to enhanced performance

  The first parameter that we are normally interested in when we are rearing animals is their live performance: this is the easiest way to have a return on investment (R.O.I.). Anyway, the improvement of animal health and management are useful as well to reduce the rearing costs (and even to achieve better production and growth).

• The power of synergy

  We are all used to hear about the concept of synergy among different substances and to use this word in any area of interest addressing solutions that allows better results in animal husbandry. It is important to define what “synergy” stands for, particularly in the microbiological area

• 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 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.

• 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).
