Introduction: Spray dried plasma (SDP) is a specialty protein source used in pig diets due to its beneficial effects on post-weaning performance and survival. Processing of SDP produces a safe product; however, further evaluation of redundant safety steps may be investigated. The objectives were to determine the effect of commercially produced ultraviolet light (UV) treated liquid porcine plasma c ...

BackgroundSpray-dried plasma (SDP) is one of additives in swine diets [1–3] and contains high protein with balanced contents of amino acids and various physiological components, such as immunoglobulins, peptides, glycoproteins, and others [4], that contribute to modulation of microbial populations [5, 6], immune responses and inflammation [4, 7, 8], and intestinal morphology [8, 9], and othe ...

IntroductionThere is an increasing global regulatory movement to ensure the judicious use of antibiotics at farms producing milk, meat, eggs, fish, and seafood to reduce the prevalence of antibiotic-resistant pathogens that affect human health. The result of these regulatory changes will reduce the length of time antibiotics can be used, may eliminate the use of antibiotics at farms that are also ...

ContextNutritional strategies that support the immune system, promote intestinal integrity and functionality, and increase tolerance to stress and disease challenges are of interest to the poultry industry. In addition, early nutrition has been recognized as an opportunity to further advance nutritional practices and improve overall performance and the health status of commercial broiler flocks. F ...

The gastrointestinal (GI) tract continues to undergo significant developmental changes in postnatal life. Environmental influences during this critical developmental period, including diet, stress and mucosal injury, have been shown to induce long-term changes in intestinal physiology and disease susceptibility in animal models(1 – 4). Similarly, in human subjects, increasing epidemiological ...

BackgroundSpray dried plasma (SDP) is a protein rich product obtained from the industrial fractionation of blood from healthy animals. Blood is collected with an anticoagulant and centrifuged to separate the blood cells. Plasma is then concentrated and spray-dried under high pressure to achieve a minimum of 80 °C throughout its substance (Fig. 1). With this procedure, proteins preserve most of ...
