Effects of dietary taurine supplementation on growth performance and immune status in growing Japanese quail (Coturnix coturnix japonica)

Abstract

The effect of dietary taurine was investigated on performance and immune responses in growing (1 to 42 d) Japanese quail. One-day-old quails of both sexes (300) were randomly allotted to 12 groups with 25 quails in each group (3 dietary treatments, 4 replicates). They were fed with maize-soybean meal-based diets containing 0, 0.01, or 0.05% taurine for 42 d. Dietary 0.01% taurine decreased food intake (P < 0.05) in the starter phase but did not affect BW gain and feed efficiency from d 1 to 42 of age. In the starter phase, dietary 0.05% taurine did not affect food intake but increased weight gain and improved feed efficiency (P < 0.05). In the grower phase, dietary 0.05% taurine did not affect weight gain but improved feed efficiency and decreased food intake (P < 0.05). In the overall period, dietary 0.05% taurine improved feed efficiency and decreased food intake (P < 0.05). The relative weights of thymus were greater in the quails given 0.01% taurine in diet (P < 0.05). The relative weights of the bursa of Fabricius and thymus were greater in dietary 0.05% taurine compared with the control (P < 0.05).The quail serum anti-Newcastle disease virus hemagglutination antibody titer in the taurine-supplemented diet had no significant effects compared with the control (P > 0.05). The response to phytohemagglutinin measured as the foot web index was significantly increased by 0.05% taurine supplementation (P < 0.05). It is concluded that the taurine-supplemented diet has a beneficial effect on immune responses and performance in growing Japanese quail.

Assessment of the efficacy of using taurine supplements to improve growth and feed utilization of juvenile starry flounder (Platichthys stellatus) given diets based on soy-protein

“…In the present study, taurine supplementation elevated serum SOD and GSH-Px activities, which were consistent with the published findings that taurine supplementation increased SOD and GSH-Px activities in juvenile black carp M. piceus (Zhang et al, 2018), yellow catfish Pelteobagrus fulvidraco (Li et al, 2016) and totoaba Totoaba macdonaldi (Banuelos-Vargas et al, 2014) fed with plant-based diets. This suggested that taurine could upregulated the synthesis of antioxidant enzymes and improved the oxidation resistence.…”

Effects of cysteamine supplementation on the intestinal expression of amino acid and peptide transporters and intestinal health in finishing pigs

“…Another possible reason is that CS could directly inhibit the action of SS distributed in the intestine, and hence reduce its immunoinhibitory effects (Yang et al ). Moreover, previous studies reported that taurine deficiency leads to abnormalities in the immune system (Schuller‐Levis & Park ), and taurine‐supplemented diet had a beneficial effect on immune responses in growing Japanese quail (Wang et al ).Thus it is possible that the improvement of mucosal immunity can be explained by the regulation of taurine.…”

Effects of the stems and leaves of Astragalus membranaceus on growth performance, immunological parameters, antioxidant status, and intestinal bacteria of quail

“…The thymus functions as a central immune organ for cellular immunity by mainly producing T lymphocytes and mononuclear macrophages. The spleen participates in humoral and cellular immunity and removes pathogenic microorganisms and aging cells from the body (Wang, Dong, et al, ). These immune tissues represent three important indexes for immune function in poultry.…”
