Piglets nutrition
At weaning, piglets are challenged by multiple sudden changes in their environment and diet. They are typically weaned between 3 to 4 weeks, when their digestive tract and immune system are still in development. As they need to adapt to new components in the diet, they are challenged with lower feed intake, digestive disorders and nutrient losses. To ensure optimal growth, piglets need (pre)starter diets formulated to meet their nutritional requirements and fully support their digestive health and immune system.
A successful nursery feeding program contains several components, but the most important are to: 1) match dietary nutrient levels and ingredients with weight and age of the nursery pig; 2) maximize feed intake, because newly weaned pigs are in an extremely energy deficient state and early intake helps maintain a healthy intestine; and 3) appropriately adjust pigs (based on age, weight, health status, etc.) to lower cost diets (usually grain-soybean meal diets) as quickly as possible after weaning to reduce total feed cost. The concepts are relatively simple and can be applied in a variety of situations around the world.

1. Introduction The gut is constantly exposed to potentially harmful contaminants from food or feed, such as mycotoxins [1]. Aflatoxin B1 is a mycotoxin produced by different species of fungi, especially Aspergillus flavus and A. parasiticus [2]. AFB1 is a potent carcinogen in humans and animals [3] and, for this reason, was classified in Group 1 of human carcinogens on the basis of toxicological data. Aflatoxins can contaminate different commodities such as cereals, nuts, dried...

1. Introduction Phosphorus (P) is an irreplaceable macroelement that regulates the metabolic and physiological functions of a living organism. It is known to take part in skeletal mineralization, as well as the formation of cell membranes, nucleic acids, and adenosine triphosphate [1]. Plants store P mainly in the form of phytate, which is not completely digestible by monogastric animals. Therefore, unabsorbed P is excreted into the environment where it is considered to be...

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...

1. Introduction Quercetin, as the foremost representative of flavonols, has been extensively investigated for its beneficial effects on health [1]. With regard to the gastrointestinal tract, quercetin received a lot of attention in treating chronic intestinal inflammation. Different mechanisms, including protection against oxidative stress, preservation of epithelial barrier function, and immunomodulatory properties in the gut, are believed to be involved [2,3]. These biological...

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....

Piglets face multiple challenges from the early stages of their life, actually since birth, a shocking experience in terms of temperature and change of environmental conditions. Besides that, piglets are born without a functional intestinal barrier and with an immature immune system. The effects of weaning and the stress suffered by young animals during that period is severe and can have big consequences, also on the long term...

1. Introduction Weaning is the most challenging event in modern pig production, which often results in reduced feed intake, decreased growth, increased risks of post-weaning diarrhea (PWD) and mortality in newly weaned piglets [1–3]. Thus, pig producers in Europe, particularly in Denmark, heavily depend on dietary supplementation of pharmacological doses (2500 to 3000 ppm) of zinc oxide (ZnO) to avert weaning related diarrhea and associated piglet mortality. However, due...

Taiwan is an island state in East Asia and located in the tropical and subtropical zone. During summer, the weather is hot and humid, and these factors will cause the intensive farming livestock to stay in high pressure and uncomfortable state, hence resulting in feed intake reduce and disease.
