1. Introduction Early-life nutrition profoundly influences the developing neonate, with some effects that are long-lasting and irreversible, as is the case for iron. Iron is an essential micronutrient for many biological processes, yet iron deficiency is considered the most prevalent micronutrient deficiency worldwide [1]. Though iron deficiency affects individuals of all age groups, women of childbearing age and children from birth to five years of age are at increased risk for...

1. Introduction
The new millennium brought a worldwide growing interest for animal welfare [1]. The livestock sector reacted by developing recommendations relevant to the wellbeing of farm animals, consequently encouraging producers to adopt and implement them. Additionally, consumer demand for better production practices contributed to the development of responsible production systems in which animal welfare principles are incorporated into daily management...

INTRODUCTION The post-weaning period may be considered critical for piglets, once they are submitted to several stress situations (SOBESTIANSKY et al., 2001) such as environmental changes (new facilities and/ or environmental temperatures), removal from the sow, replacement of liquid with solid diets, and social tensions arising from getting animal grouped back after being separated (FERREIRA et al., 2001). Thus, aiming to minimize the stress which is observed in this initial...

Introduction The optimal concentration of nutrients required by growing pigs generally decreases over the growing-finishing period with a phase feeding program used as an attempt to meet the needs of the pigs over the changing requirements. Thus, in commercial production, phase feeding is thought to improve economics and reduce nitrogen excretion by more closely meeting the pig’s nutrient requirements compared to feeding fewer phases. However, in practice, it is...

1. Introduction African swine fever (ASF), a fatal disease in domestic pigs and wild boar, has become a serious economic threat to the pig farming sector with global ramifications, more than ever underlined by the recent spread to China, Mongolia and Southeast Asia [1]. It is causing tremendous losses in the industrial pig sector but also affecting livelihood of small-scale pig holders in rural areas. In 1921, the disease was first described in Africa, where the disease...

Introduction Sodium and chloride are involved in several of the body’s processes, such as the sodium potassium pump and osmotic regulation. Traditionally, the most common source of Na and Cl in swine diets is added salt. Hagsten et al. noted improvements in ADG and F/G when at least 0.10% of salt was added to corn-soybean meal diets for pigs from 40 to 200 lb. However, Alcantara et al. reported that in corn-soybean meal diets for growing pigs (55 to 110 lb), ADG and ADFI...

1. Introduction Astroviruses are emerging viruses in the family Astroviridae, which is divided into two genera: Avastrovirus andMamastrovirus[1]. Astroviruses are non-enveloped, 28–30 nm positive-sense, single stranded RNA viruses [2] that can cause disease and be detected in the feces from a wide variety of mammals and birds [3–9]. Porcine astroviruses (PoAstVs) are genetically diverse and are distributed worldwide [10] with five genetic lineages...

At weaning, piglets suffer from immunological, environmental, nutritional and social stress, consequently affecting the gut health and growth performance. Supplementation of probiotics is considered as one of the strategies to maintain the intestinal health and minimize the negative effects of the weaning stress in piglets. Probiotic, Bacillus amyloliquefaciens CECT 5940 is a natural spore - forming bacteria, which supports gut health and improves growth performance in poultry....

Introduction The association of all the stressors related to early weaning of piglets results in reduction in daily feed intake, especially during the first week. The interruption of feed intake in this phase results in intestinal villous atrophy and increased crypt depth (Pierce et al, 2005). According to Pinheiro & Machado (2007), the performance of piglets in the first week after weaning is strongly correlated with the weight at the end of the nursery phase, and the...

Introduction & objective: Post-weaning Escherichia coli diarrhea (PWD), also called post-weaning enteric colibacillosis, in pigs remains a major cause of economic losses for the pig industry, due to either piglet death, or poor weight gain in surviving piglets [1,2]. PWD typically causes mild to severe watery diarrhea between 5 and 10 days after weaning and is primarily caused by enterotoxigenic Escherichia coli (ETEC). The most common adhesins found on ETEC from PWD in pigs are...
