The effect of arginine dietary supplementation in broiler breeder hens on offspring humoral and cell-mediated immune responses

Abstract

Arginine, macrophage, maternal diet, offspring immunity.Submitted: September/2013 Approved: January/2014 ABSTRACTThe influence of supplementing the diet of broiler breeder hens with arginine (Arg) on their offspring's humoral and cell-mediated immune response was evaluated in two experiments. In experiments I and II, breeder hens were fed diets containing graded levels of Arg (0.943,

“…However, information on the effects of the GAA supplementation on intestinal morphology of quail is limited and most of the studies, examine the effects of arginine on gut morphology and function of other poultry. Through arginine supplementation in broiler chickens, an improvement in the duodenum morphology characteristics and jejunal and ileal villus height and absorptive surface area were reported (Khajali et al 2014;Murakami et al 2014). In agreement with a recent study done by Ahmadipour et al (2018), our results showed improvements in the villus height and absorptive surface area and a decrease in crypt depth in the ileum by GAA supplementation.…”

“…In the present study, by adding GAA to the diets, there was a marked increase in EP, EW and EM. The EP data suggested that quails fed 1.8 g/kg of dietary GAA had the optimum EP while the ideal level of GAA for EW and EM was 1.2 g/kg, which is in discordance with Murakami et al (2014). They have reported no observed effects through GAA supplementation on productive traits in laying quails.…”

“…To investigate the effect of GAA in breeder laying birds, Murakami et al (2014) increased the level of GAA up to 0.18% in the diets of meat-type quail breeders, but no changes in egg production rate was observed. However, an improvement in intestinal morphology was reported in broiler chickens following dietary GAA inclusion (Ahmadipour et al 2018).…”

“…As mentioned, creatine and arginine induce different nutritional and physiological effects, but the effect of GAA supplementation in the exact recommended level of dietary arginine on desired productive traits of laying quails and their antioxidant systems are unclear. In experiment done by Murakami et al (2014), the investigators used conventional diets with extra supplied arginine levels (15.6 vs. 12.6 g/kg). With regarding arginine level in the diet, supplying sufficient methyl donors such as methionine or betaine in accordance with that, is necessary and each failure into accomplishing can significantly impact performance (Keshavarz and Fuller 1971).…”

“…Meat-type quails fed 0.4 g Arg/kg of the diet had significantly higher (p<0.05) relative weight of bursa compared to the other groups. Similarly, Murakami et al (2014) reported that the addition of Arg in broiler chickens' diet resulted in greater weight and dimensions of the bursa compared to nonsupplemented broilers. Kwak et al (1999) reported that broiler chicks fed Arg deficiency diets had lower weight of thymus as a percentage of live BW.…”
