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: Porcine Epidemic Diarrhea (PED) is caused by PED virus (PEDV) that is a member of the order Nidovirales, family Coronaviridae and genus Coronavirus. PED is a severe enteric disease that causes economic losses worldwide. Maternal passive immunity can prevent losses in suckling piglets during the period of immature immune system. Sow colostrum is the most abundant and easily accessible resource of a farm. The aim of this study was to evaluate an immunological...
Introduction: Since late 2010, new variants of porcine epidemic diarrhea virus (PEDV) have arisen in China, spread to Asia and North America in the end of 2013, and cause severe watery diarrhea in pigs of all ages and extremely high mortality rate in neonatal piglets resulting in significant economic losses. Recent studies indicate that the spike (S) gene of Taiwan new PEDV strains are closely related to global non-S INDEL PEDVs but significantly different from historic...
Introduction: The aim of this study was to compare the effect of post-weaning treatment of piglets with zink oxide (ZnO) and colistin on health, production and Escherichia coli shedding. Materials and Methods: During two successive weaning rounds, a randomized control study was performed on three commercial pig herds. In each herd, four groups of weaners were created that either received colistin in the feed (CF) (Promycine® 400 IU/mg, premix,...
Introduction: The oral cavity of animals harbors an extensive microflora, including indigenous commensals and other microorganisms. Oral microbiota may play an important role in the protection of the host against pathogenic infection through the inhibition of colonization of pathogens or growth competition. Especially, the composition of oral microbiota of piglets at the nursery phase, at the critical time to establish a normal flora for life-time, would be drastically altered...
Introduction: Newborn piglets are at risk for developing iron deficiency because they are born with limited iron stores and sow milk provides them with only ±1 mg of iron per day. Iron deficiency leads to anemia characterized by a low concentration of iron-containing hemoglobulin (Hb) in red blood cells. Therefore, iron administration to piglets within the first week of life is common practice in pig farms. The aim of this study was to investigate the effect of iron...
Mike Tokach (Kansas State University) explains how to remove costs by reviewing amino acids and energy levels, and the close relation between genetics and nutrition, during the Nutrimas workshop....
Introduction With the rise of antimicrobial resistance and the more frequent identification of multidrug resistance strains, as well as a lack of research into the development of new antimicrobial agents, scientists are increasingly interested in tests of active substances derived from plants due to their ease of availability, safety, and cost effectiveness (Albert, 2021). The use of medicinal plants in animal nutrition has increased due to their positive properties such as...
Introduction: Increased litter sizes due to hyper prolific sows have led to litters with up to 30% of piglets being born with signs of intra-uterine growth restriction (IUGR). IUGR piglets have lower survival rates and are more likely to have empty stomachs at 24 hours. In addition, it is estimated that IUGR piglets can only consume 100 g of the recommended 250 g of colostrum within the first 24 hours. The gastric emptying rate of these piglets might influence their...
Introduction: They are several benefits of using IgY as a feed additive. Egg yolk or yolk plasma as a feed additive may improve the production results by two ways: 1) stimulation of growth rate through metabolism improvement and/or increasing feed intake; 2) stabilization and enhancing the gastrointestinal tract immune protection. The aim of the study was to compare two ways of IgY administration in the peri-weaning period (1 week before and 2 weeks after weaning) and to...
Introduction: Since 2006, Antibiotic growth promotors (AGP) are banned in the EU. Questions are raising in EU as well as in other parts of the world about the effectiveness of alternatives to replace AGPs. Commonly used alternatives in EU are products based on butyric acid. Butyric acid (C4) is a short chain fatty acid (SCFA) with a biological role, consistently present in the intestinal ecosystem, as it is naturally produced by fermentation of polysaccharides by the intestinal...
Introduction: Saccharomyces cerevisiae boulardii is a probiotic yeast with an established history of use for the prevention and/or treatment of diarrhoea and chronic inflammatory disease in human medicine. More recently, S. boulardii has also been used in the pig industry to increase performance and reduce pathogen burden during vulnerable early life stages such as post-farrowing and weaning. Recent advances in DNA sequencing technology are now able to understand the host...
Introduction: The piglets TGI is not yet completely developed after weaning for solid diet digestion and absorption, so different ingredients are used to minimize these problems, improve feed intake and body weight gain during nursery phase. Yeast has been used as an important source of nucleotides, proteins, amino acids, MOS and β-glucans. Based on this, the aim of this study was to evaluate the supplementation of yeast as a source of nucleotides in piglet’s diet...
Introduction: Appropriate nutrient digestibility is a key to animal health and growth performance, particularly in post-weaning pigs. Compounds with anti-inflammatory or anti-oxidative properties have potential to support gut integrity and growth performance when included in diets for pigs. Isoquinoline alkaloids (IQ) derived from the Papaveraceae plant Macleaya cordata exert anti-inflammatory effects, whereas naringin (NRG), a bitter-tasting flavanone glycoside from...
Introduction: Increased litter sizes due to hyper prolific sows have led to litters with up to 30% of piglets being born with signs of intra-uterine growth restriction (IUGR) and thereby needing additional care or/and nutritional supplements. Up to 48 % of piglets that die before weaning have empty stomachs, and it is estimated that piglets need at least 250 g of colostrum within the first 24 hours to survive. It has previously been estimated that IUGR piglets only...
Introduction: Phosphorus is an element with potential impact on the intestinal microbiota of pigs. Studies revealed that bacterial growth was limited in the intestine feeding low concentrations of phosphorus and that ileal bacteria increased with higher calcium and phosphorus feed contents, whereas there was no effect on bacterial numbers in the colon. Therefore, the aim of this study was to evaluate the influence of varying phosphorus levels in diets of piglets on the bacterial...
Introduction: Previous research showed that one out of three sows produces insufficient colostrum and milk for the offspring. This may lead to reduced piglet performance. The most obvious solution is to increase the colostrum and milk production of the sow. However, optimizing the composition of sow colostrum and milk may also be a valuable preventive measure. Therefore, knowledge of the composition of the mammary secretions and influencing factors is important. The aim of this...
Introduction: Newly weaned pigs require 50-100 mg/kg of zinc in feed to meet dietary requirements (National Research Council). The addition of high levels of zinc oxide (> 2000 mg/kg) in nursery diets is often used as a preventive measure for Escherichia coli diarrhea and to improve growth performance. The mechanism y which this occurs is still not fully understood, however, it is proposed that zinc oxide has an effect on the gastrointestinal microbiome, due to its...
Introduction: The effects of the oral supplementation of probiotics on the performance (weight gain and feed intake) and intestinal histo-morphology of the duodenal, jejunal, and ileal mucosa (villus height, width, and perimeter and crypt depth) of two different genetic lines (purebred Large White or crossbred Large White x Landrace) of suckling piglets. Materials and Methods: The suckling piglets were evaluated between 2 and 19 days of age. In total, 276...
