Effect of microencapsulated sodium butyrate dietary supplementation on growth performance and intestinal barrier function of broiler chickens infected with necrotic enteritis

Dietary encapsulated essential oils and organic acids mixture improves gut health in broiler chickens challenged with necrotic enteritis

“…In the present study, NE challenge decreased the BWG and AFI and increased the feed/gain ratio in chicks fed a basal diet during the infection period, which is consistent with the results reported by Song et al [28] and Wu et al [37]. Birds fed a commercial blend of thyme, carvacrol and organic acids (BLJ) showed improved FCR and decreased AFI but no statistical differences in BWG regardless of NE infection.…”

“…Two previous studies demonstrated that feeding blends of sorbic acid, fumaric acid and thymol to broiler chickens reared under conventional conditions changed the intestinal morphology, resulting in longer villi and a greater VH/ CD ratio [35,47]. In addition, several studies have shown improved gut morphology and decreased gross intestinal lesion scores in NE-infected broiler chickens fed either EO-supplemented [18] or OA-treated diets [28]. Intestinal bacterial translocation to internal organs and serum FITC-D levels post-FITC-D gavage are also two important parameters commonly used to indirectly evaluate quality and extent of intestinal injury [54].…”

“…Body weight (BW) and feed intake from each replicate cage were measured on d 1, 21 and 42. Average body Table 1 Composition and nutrient levels of the experimental basal diet, on an as-fed basis unless stated otherwise, % Items 1 to 21 d 22 to 42 Three independent observers blinded to the study groups scored the NE gut lesions on a scale of 0 (no lesions) to 4 (severe lesions) as previously described [28]. Concurrently, ∼1-cm-long jejunal samples taken from between Meckel's diverticulum and the proximal end of the jejunum were snap-frozen in liquid nitrogen and stored at − 80°C for mRNA analysis.…”

“…[22], Campylobacter jejuni [26] and C. perfringens [27]. For example, in broiler chickens, adding coated sodium nbutyrate increased body weight gain and alleviated NEassociated gut injury by upregulating jejunal tight junction protein mRNA levels [28]. Challenged birds given an OAs blend containing formic, acetic, propionic, sorbic, caprylic and capric acids showed improved feed efficiency during the grower stage [29].…”

Efficacy of crystalline methionine and microencapsulation methionine in diets for Pacific white shrimpLitopenaeus vannamei

“…There has been progress made on the effects of slow‐release CAAs in diets. Many new techniques have been proposed, such as encapsulation or microencapsulation, in an attempt to reduce leaching losses and improve the bioavailability of CAAs (Niu, Chang, & Jia, 2015; Song et al., 2017). Coated amino acids can be used to determine reference dietary AA patterns of aquatic animals (Alam, Teshima, Yaniharto, Ishikawa, & Koshio, 2002) and the retardation of their absorption from the intestine proteins (Alam, Teshima, Koshio, & Ishikawa, 2004).…”
