| 1 | Functional roles of taurine,L-theanine,Lcitrulline,and betaine during heat stress in poultry显示文摘Heat stress(HS)is an important environmental stress factor affecting poultry production on a global scale.With the rise in ambient temperature and increasing effects of global warming,it becomes pertinent to understand the effects of HS on poultry production and the strategies that can be adopted to mitigate its detrimental impacts on the performance,health,welfare,immunity,and survival of birds.Amino acids(AAs)have been increasingly adopted as nutritional modifiers in animals to ameliorate the adverse effects of HS.They are essential for protein synthesis,growth,maintenance,reproduction,immunity,stress response,and whole-body homeostasis.However,HS tends to adversely affect the availability,transport,absorption,and utilization of these AAs.Studies have investigated the provision of these AAs to poultry during HS conditions,and variable findings have been reported.Taurine,L-theanine,and L-citrulline are non-essential amino acids that are increasingly gaining attention as nutritional supplements in HS animals.Similarly,betaine is an amino acid derivative that possesses favorable biological properties which contributes to its role as a functional additive during HS.Of particular note,taurine is negligible in plants,while betaine,L-theanine,and L-citrulline can be found in selected plants.These nutrients are barely found in feed ingredients,but their supply has been shown to elicit important physiological roles including anti-stress effects,anti-oxidative,anti-inflammatory,gut promoting,and immunomodulatory functions.The present review provides information on the use of these nutritionally and physiologically beneficial nutrients as functional additives to poultry diets during HS conditions.Presently,although several studies have reported on the positive effects of these additives in human and murine studies,however,there is limited information regarding their utilization during heat stress in poultry nutrition.Therefore,this review aims to expound on the functional properties of these nutrients,their potentials for HS alleviation,and to stimulate further researches on their biological roles in poultry nutrition. | Victoria Anthony Uyanga Emmanuel OOke Felix Kwame Amevor Jingpeng Zhao Xiaojuan Wang Hongchao Jiao Okanlawon MOnagbesan Hai Lin | 2022 | Journal of Animal Science and Biotechnology2022，13，4： | 3 |

| 11 | Effects of arginine replacement with L-citrulline on the arginine/nitric oxide metabolism in chickens:An animal model without urea cycle显示文摘Background This study examined the efficacy of L-citrulline supplementation on the arginine/nitric oxide metabolism,and intestinal functions of broilers during arginine deficiency.A total of 288 day-old Arbor Acre broilers were randomly assigned to either an arginine deficient basal diet(NC diet),NC diet+0.50%L-arginine(PC diet),or NC diet+0.50%L-citrulline(NCL diet).Production performance was recorded,and at 21 days old,chickens were euthanized for tissue collection.Results The dietary treatments did not affect the growth performance of broilers(P>0.05),although NC diet increased the plasma alanine aminotransferase,urate,and several amino acids,except arginine(P<0.05).In contrast,NCL diet elevated the arginine and ornithine concentration higher than NC diet,and it increased the plasma citrulline greater than the PC diet(P<0.05).The nitric oxide concentration in the kidney and liver tissues,along with the plasma and liver e NOS activities were promoted by NCL diet higher than PC diet(P<0.05).In the liver,the activities of arginase 1,ASS,and ASL,as well as,the gene expression of i NOS and OTC were induced by PC diet greater than NC diet(P<0.05).In the kidney,the arginase 1,ASS and ASL enzymes were also increased by PC diet significantly higher than the NC and NCL diets.Comparatively,the kidney had higher abundance of n NOS,ASS,ARG2,and OTC genes than the liver tissue(P<0.05).In addition,NCL diet upregulated(P<0.05)the m RNA expression of intestinal nutrient transporters(EAAT3 and PEPT1),tight junction proteins(Claudin 1 and Occludin),and intestinal mucosal defense(MUC2 and p Ig R).The intestinal morphology revealed that both PC and NCL diets improved(P<0.05)the ileal VH/CD ratio and the jejunal VH and VH/CD ratio compared to the NC fed broilers.Conclusion This study revealed that NCL diet supported arginine metabolism,nitric oxide synthesis,and promoted the intestinal function of broilers.Thus,L-citrulline may serve as a partial arginine replacement in broiler’s diet without detrimental impacts on the performance,arginine metabolism and gut health of chickens. | Victoria Anthony Uyanga Lijing Sun Yu Liu Meiming Zhang Jingpeng Zhao Xiaojuan Wang Hongchao Jiao Okanlawon M.Onagbesan Hai Lin | 2023 | Journal of Animal Science and Biotechnology2023，14，3： | 1 |
