• Intestinal metabolism of weaned piglets fed a typical United States or European diet with or without supplementation of tributyrin and lactitol

  The aim of the study was to investigate the effects of supplementation of a microencapsulated blend of tributyrin and lactitol (TL) to a standard European (EU) diet without antibiotic growth promoters on intestinal metabolism and mucosa development of weaned piglets and to compare it with a standard US diet containing animal proteins, zinc oxide, copper sulfate, and carbadox.

• Tributyrin and lactitol synergistically enhanced the trophic status of the intestinal mucosa and reduced histamine levels in the gut of nursery pigs

  At 28 d after birth, the piglets were weighed and allotted into four groups and fed a standard nonmedicated diet (control) or the control diet with tributyrin (butanoic acid 1,2,3-propanetriyl ester; 10 g/kg), or with lactitol (β-Dgalactopyranosyl-(1→4)-D-sorbitol; 3 g/kg), or with tributyrin (10 g/kg) plus lactitol (3 g/kg).

• Microencapsulated Sorbic Acid and Pure Botanicals Affect Salmonella Typhimurium Shedding in Pigs: A Close-Up Look from Weaning to Slaughter in Controlled and Field Conditions

  The aim of this study was to assess the efficacy of a combination of sorbic acid, thymol, and carvacrol in reducing the prevalence and shedding level of Salmonella Typhimurium in pigs either in a controlled challenge environment or in a production setting.

• Lipid microencapsulation allows slow release of organic acids and natural identical flavors along the swine intestine

  The purpose of the present work was to investigate the in vivo concentrations of sorbic acid and vanillin as markers of the fate of organic acids (OA) and natural identical flavors (NIF) from a microencapsulated mixture and from the same mixture non-microencapsulated, and the possible consequences on the intestinal microbial fermentation.

• Effects of microencapsulated complex of organic acids and essential oils on growth performance, nutrient retention, blood profiles, fecal microflora, and lean meat percentage in weaning to finishing pigs

  A total of 90 pigs (6.47 ± 0.27 kg; 21 d of age) were used in this 22 wk feeding trial to evaluate the effect of microencapsulated complex of organic acids and essential oils (MOE) on growth performance, nutrient retention, blood profile, fecal microflora, and lean meat percentage in pigs.

• Feeding a microencapsulated blend of organic acids and nature identical compounds to weaning pigs improved growth performance and intestinal metabolism

  One-hundred and seventy weaning pigs were divided in two groups, and housed in 34 pens (17 replicates, 5 pigs each). Piglets received a basal diet without (control diet, CTR) or with the addition of a microencapsulated blend of organic acids and nature identical compounds at 3 kg/ton (AviPlus®, EP1391155B1, Vetagro SpA, Italy).

• Effect of supplemented microencapsulated zinc oxide and organic acids and pure botanicals on growth performance, nutrient digestibility, blood profiles, feces microflora, and zinc level of feces in weanling pigs

  A total of 125 crossbred pigs with initial body weight (BW) of 7.66 ± 1.30 kg were randomly distributed into one of five dietary treatments. Each treatment had five replicate pens with five pigs per pen.

• How AviPlus®S can help animals during stressful periods

  Despite common use, 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 and alter the physiological equilibrium of the organism.

• Nature-Identical Compounds and Organic Acids Reduce E. coli K88 Growth and Virulence Gene Expression In Vitro

  Post-weaning diarrhoea (PWD) is one of the long-standing challenges in pig husbandry. Due to the risks of resistance caused by antibiotics (AB) misuse, conventional treatments against Escherichia coli K88 (E. coli K88), the PWD etiological agent, urgently need to be replaced. Organic acids (OA) and nature-identical compounds (NIC) are currently finding a central role in infection management thanks to their recognized antimicrobial activity.

• Towards zero zinc oxide: feeding strategies to manage post-weaning diarrhea in piglets

  This article reviews the utilization of ZnO in piglets, the biological rationale behind its powerful activity, and the emerging threats that are leading towards a significant reduction in its use. Finally, a wide analysis of the strengths and weaknesses of innovative alternative strategies to manage PWD at the nutritional level is given.
