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 It is generally thought that as diets are ground to a smaller mean particle size, a linear improvement in nutrient utilization and pig performance will be observed. Research has demonstrated this benefit when particle size is reduced from 1,000 microns to approximately 600 microns. However, further reduction of particle size below 600 microns has not shown consistent benefits when fed to nursery pigs and has been reported to reduce feed intake and gain in finishing...

INTRODUCTION Mycotoxins are considered important contaminants of maize-based products (Abdallah et al. 2015). The natural occurrence of aflatoxins, fumonisins, zearalenone, ochratoxin A, trichothecenes, patulin and penicillic acid is often observed in animal feed, and include the concomitant occurrence of two or more mycotoxins. These natural contaminants of cereals are found worldwide mainly in corn and its derived products. Pigs are highly susceptible to...

Introduction In nutritional programs for swine, antibiotic and anti-microbial additives that act as growth promoters have been used in sub-therapeutic and constant doses ever since the 1950s. In post -weaning, these additives promote an average increase of 16.4% in weight gain and 6.9% in feed efficiency (Cromwell, 1991). However, despite of the evidenced ability on improving the growth performance, the use of these products in animal nutrition has been restricted by virtue of...

1. Introduction Gastrointestinal tract (GIT) health (‘gut health’) is a term used very commonly, and is the subject of enormous interest currently throughout the world, yet generally lacks a precise and unifying meaning or aetiology. Several recent articles and reviews (e.g., Adewole et al., 2016; Bischoff, 2011; Celi et al., 2017; Jayaraman and Nyachoti, 2017; Kogut and Arsenault, 2016; Moeser et al., 2017; Pluske, 2013) have summarized valuable and timely...

The objective of the study was to determine to what extent B. subtilis DSM 32315 ( BS ) probiotic can ameliorate the negative effect of weaning stress on intestinal microbial profile and integrity, and growth performance, in piglets fed low or high crude protein (CP) diets. Seventy-two piglets (initial weight 7.61 ± 0.55 kg) were allotted to 4 diets in a randomized complete block design in a 2 × 2...

Background Efficient natural alternatives to antibiotics and high level of zinc oxide are urgently needed for the control of post-weaning diarrhoea in piglets. Silvafeed ® Nutri P is a blend of plant extracts rich in bioactive polyphenols, which have been extensively studied for their biological properties (e.g. antispasmodic, antimicrobial, antioxidant and anti-inflammatory) and potential health benefits. Recently, the effectiveness of Silvafeed® plant...

Background and objectives
Altering feed composition can be an alternative to the therapeutic usage of zinc oxide (ZnO) to maintain piglet performance and to reduce post-weaning diarrhea. Supplementing the diet with the right functional fiber source is one way to replace ZnO. Inert fiber sources may improve the gut health of weaned pigs by modulating the activity of intestinal microbiota (Molist et al., 2011). The aim of the study was to investigate the effect...

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...

Background and objectives Without clear and accurate definition of gut health status, the design of feeding trials to study alternatives to in-feed therapeuticals (antibiotics and zinc oxide) is a challenge. Growth performance and clinical signs of scours remain the key measurements for feed evaluation, but they may not allow to discriminate solutions in a repeatable manner. Niewold (2015) proposed faecal myeloperoxidase (MPO) as a biomarker of inflammatory response in the gut...

In the pig industry, the use of high levels of zinc oxide (ZnO) is used for prevention and treatment of diarrhoea in weaning piglets, but the mechanism of action of Zinc has not yet been known. Some studies tested some hypothesis as WANG ET AL that demonstrated the ZnO alters the expression of intestinal proteins that are related to the regulation of oxidative stress, cell proliferation and apoptosis in weanling piglets 1 . In light of these studies, this work intends to propose a...

Background
The Danish pig production industry is characterized by high levels of health and productivity. In 2018, the Danish production reached 32.5 million pigs, of which 18 million were slaughtered in Denmark, while 14 million piglets were exported to mainly Germany and Poland for further fattening. The export of growing pigs began in 2004 and the demand for Danish weaners has increased annually. Because of the large export of pork and weaners, Danish...

Background and objectives Fungal fermented products and their derivatives contain several compounds and may play a role in replacing antimicrobials in piglet diets. During fermentation, microbial enzymes produced by fungi will degrade feed material and fungal cell wall material is produced. In our study, fungal fermented rye is evaluated, which showed to bind pathogens and exhibit a prebiotic effect in the intestinal tract. Moreover, the fungal material is known for its...

Nutritional strategies to minimize weaning negatives impacts on piglet’s health and performance are quite as important at piglet’s production system. At this stage, they are vulnerable to stress consequences caused by nutritional, environmental, social and immunological changes. The negative impacts of the weaning on performance are related with intestine villous injuries and subsequent decrease on nutrients digestibility causing diarrhea increase. The interest of viable...
