Botanicals represent a wide class of complex compounds that naturally contain active principles with numerous biological functions. Among them, the anti-inflammatory and antioxidant actions are of key interest to support intestinal health during stressful phases. The aim of this study was to investigate the ability of a thymol-based blend of botanicals (BOT) to protect intestinal Caco-2 cells from the damages induced by an inflammatory challenge in vitro. Caco-2 cells were differentiated on...
Introduction On average, piglet livability in Europe is 83%, ranging from 70% to 90%. It is determined by the number of still births and pre-weaning mortality in a given litter. With the increasing litter size, piglet survival is a persistent challenge to pig producers. This calls for a feeding and management strategy to improve nutrition and wellbeing of the sow in the transition phase covering late gestation, farrowing, lactation and breeding. The transition period...
Introduction The major goal of the swine industry is to minimize neonatal mortality and improve weaning weights of neonatal pigs because their adaptability to weaning and their rates of growth to market weight are positively affected by weaning weight [1]. The total net profit of a swine production unit is primarily determined by both the number and size of piglets produced per year per sow [2]. Recent attempts to increase litter size have led to increased prevalence of...
A new educational program, hosted by the American Feed Industry Association (AFIA), will focus on biosecurity preparedness in the animal food industry. The program, “ Biosecurity: Preparedness Must Be Perpetual ,” will take place on Jan. 25, 2023, in conjunction with the 2023 International Production & Processing Expo, taking place Jan. 24-26 in Atlanta,...

The United States Department of Agriculture reported that sow mortality ranges from 2.5% to 3.7% each year, depending on herd size 1 . It also was stated that annual mortality rates of sows in typical confined-sow herds should not exceed 3% 2 . In contrast, some sow herds experience annual losses of at least 10% of inventoried females 3-6 . The reasons for sow mortality are poorly understood; however, larger herd size, greater parity, and short lactation length...
The majority of pig and poultry diets are composed of about 70% maize or wheat, 20% soybean meal or other similar protein sources, and 10% micro-ingredients. Although this is a simplification, it illustrates the point that the majority of pork, poultry, and eggs are produced using a limited range of ingredients. In addition, it is important to note that feed cost is about 60-70% of overall production cost. And, as feedstuff prices continue to be prohibitively high, with detrimental...
Introduction: S. suis is recognised as major swine pathogen associated with the intensification of the swine industry worldwide. Until now limited number of effective vaccines are available. Therefore antimicrobial treatment is considered as one of the most effective approach for the control of streptococcal meningitis and polyarthritis. Beta-lactam antibiotics and especially amoxicillin is considered as drug of first choice based on several criteria such as the PK/PD...
Introduction The processing of food grains into flour, vegetable oil, alcohol and biofuels offloads quantitatively variable, chemically diverse non-starch polysaccharides (NSP) into co-products (Bach Knudsen, 2014). Rapidly increasing human demand and random adverse climate change-related events are disrupting global grain markets, forcing producers into greater dependency on co-products for sustainable, cost-effective pig feeding strategies. Chemical and quantitative...
Over the last 30 years, diseases caused by emerging swine viruses (ESV) have acquired great relevance, more than in other species. Diseases caused by porcine reproductive and respiratory syndrome virus (PRRSv), high pathogenicity porcine epidemic diarrhea virus (PEDv), porcine circovirus type 2 (PCV-2), and influenza virus H1N1pdm09 had great economic impact. Others, however, such as porcine enteroviruses, porcine toroviruses (PToV), porcine sapelovirus (PSV), porcine bocavirus (PBoV),...
1. Introduction β-mannans (BM) are commonly present in a wide variety of feedstuffs, including soybean meal, and have been described as one of the major anti-nutritional factors for non-ruminant animals (Bertechini, 2013). Dietary BM are associated with negative effects in pigs and broilers, such as increased intestinal viscosity and decreased nutrient digestibility (Shastak et al., 2015). Despite being naturally found in non-pathogenic substances, these compounds may...
Introduction Animal welfare has been increasingly included in business agreements and with humane slaughter is a key area of interest (von Keyserlingk and Hötzel, 2015). Retailers, restaurants, and food service companies seek kinder and more responsible farm animal practices (Grandin, 2010; Bayvel et al., 2012). Yet, it is a consensus that changes in attitudes and practices of stakeholders are required to improve farm animal welfare at slaughter (Paranhos da Costa et al.,...
