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.
Introduction Nursery pigs often experience a lag in growth performance when transitioning from sows’ milk to dry feed during weaning. The lag is caused by several factors, including the dietary and environmental stresses associated with weaning. This post-weaning challenge can be associated with suppressed performance, diarrhea, and other intestinal health problems. While compensatory gain may occur as pigs become accustomed to solid feed, previous stresses may diminish...

There are multiple approaches a swine nutritionist can take in diet formulation: maximize performance, minimize cost, or maximize profit. Within each of these approaches, there are suboptions to decide from: Growth performance basis Maximize average daily gain (ADG) Minimize feed efficiency (F/G) Cost reduction basis Minimize cost per kg of diet Minimize feed cost per kg of...

Introduction
The feed intake of swine is a deciding factor for both health and growth. Its relationship with growth is obvious; it is the nutrient supply above maintenance which sets the upper limit to the growth of an animal. The impact of feed intake on health is underappreciated. Experiments with E. coli infections showed this nicely. These experiments aimed at screening feed additives against E. coli. However, each attempt to find effective additives, other...

The intestinal mucosa possesses an extensive surface area and is exposed to a large and diverse number of microorganisms and potentially antigenic proteins throughout the lifetime of a pig. The mucosal epithelium is capable of assimilating vital nutrients while simultaneously excluding ingested pathogens and other harmful materials. In mature swine, an array of gastrointestinal defense processes act rapidly and collectively to intercept, neutralize or eliminate harmful antigens and microbes...

World production of lipid sources Global production of vegetable oils has increased dramatically over the last 20 years with approximately 168 million metric tonnes produced in 2014. The primary vegetable oils produced in the world include palm oil (35 % of the total production), soybean oil (26 %), rapeseed/ canola oil (15 %), and sunflower oil (9 %). Other vegetable oils account for only about 15 % of the market, with palm kernel oil, cottonseed oil, peanut oil, coconut oil,...

Abstract The aim of this study was to investigate the effect of supplementation of Cordyceps militaris fermentation products (CMF) on growth performance and immunocompetence of piglets. The study involved three groups of animals, which were supplemented with CMF (500, 1000 and 1500 mg/kg feed), and a control group. CMF supplementation significantly increased growth performance in weaned piglets. Bodyweight gain, average daily gain and feed intake in animals supplemented with...

Weaning is one of the most stressful periods in the life of a pig, resulting in lower feed intake, poorer growth, and higher morbidity and mortality, particularly during the first weeks after weaning or until the immune system has become more fully developed. Weaning is a stress, independent of weaning age, caused by the abrupt separation from the sow and by other stressors related to changes in the physical and social environment, mingling with pigs from different litters, dietary...

Introduction Weaning removes young pigs from the passive immune protection they receive from the milk of the sow and increases their susceptibility to enterotoxigenic E. coli infection [1]. Earlyweaned pigs often exhibit an underdeveloped immune system, digestive disorders and post-weaning diarrhea [2]. Enterotoxigenic E. coli not only colonize the small intestine, but can also...

Introduction
Weaning pigs from the sow is one of the most stressful events in the pig’s life that can contribute to intestinal and immune system dysfunctions that result in reduced pig health, growth, and feed intake, particularly during the first week after weaning. Technological improvements in housing, nutrition, health, and management have been used to...

Background Weaning is a stressful period for piglets due to environmental, social and nutritional changes. During this period, pigs are also vulnerable because of their immature immune and digestive systems [1]. The stress may result in depressed feed intake which may lead to poor performance and changes in the intestinal structure and microbiota, thus increasing the...

How would you feel if one day – seemingly out of the blue – someone took away your favorite beverage and replaced it with something they said was good for you? Would you scream frustration? Would you refuse to do anything? Would you sulk? If you said, “yes”, you agree with most weaning piglets: Change can be hard. The weaning period can be challenging for pigs and swine producers alike. The transition from sow’s milk to dry feed...

Introduction: Potassium diformate, a double-salt of formic acid, has been shown in numerous trials to improve health and performance in piglets, growing-finishing pigs and sows. Thus, potassium diformate (KDF) has been approved in the European Union as the first non-antibiotic growth promoter for use in swine. The effect of KDF is often described as strong antimicrobial and digestibility enhancing. However, data on its use in sows under tropical conditions...

Weaning is a critical period in a pig’s life; the pig must cope with separation from the sow, the transition from highly digestible milk to a less digestible and more complex solid feed, a new environment, movement and separation from littermates, and exposure to unfamiliar pigs. During the first week pigs have a reduced growth rate, which is related in part to low and variable water and feed intake. 1,2,5 Additionally, the newly weaned...
