“…Another study reported that taurine supplementation recovered mitochondrial damage in breast muscle induced by heat stress (Lu et al 2019). We speculate that the improved histomorphological features of the pectoral muscle in heat-stressed broiler in the present study could be due to the antioxidant effect of taurine (Xu et al 2020).…”

“…We did not find any published literature where muscle histomorphology has been investigated under supplementation of taurine in heatstressed broiler. Furthermore, most of the published studies are dealing with meat quality parameters such as cooking loss, shear force, meat colour and drip loss in broiler under supplementation of taurine (Huang et al 2014;Xu et al 2020). Therefore, it is difficult to pinpoint the exact mechanism of recovery of microscopic changes in muscle tissuesaffacted by heat-stress in the current study.…”

In the past, taurine was not considered essential in poultry diet; however, heavy reliance on plants derived feed ingredients and environmental stresses have compelled its application inevitable. Six hundred day old male broilers (Hubbard) were supplementation with taurine at the level of 0 (TAN0), 2.5 (TAN2.5), 5 (TAN5) and 7.5 g/kg (TAN7.5) in drinking water during heat stressed conditions for a period of 35 days. On overall basis, feed intake was not significantly (p>.05) different between the treatments. At the end of the experiment, weight gain was significantly (p<.05) higher in the treatment groups. On the overall basis, FCR was significantly (p<.01) lower in the treatment groups. Abdominal fat weight was significantly (p<.01) lower in TAN5 and TAN7.5 compared to the control group. On the slaughter age (35 days) muscle fibre diameter (MFD), muscle fibre cross sectional area (MFCSA), muscle fascicle diameter (MFASD) and muscle fascicle cross-sectional area were significantly (p<.05) higher in TAN7.5 compared to the control. The results indicated that growth performance was enhanced in taurine supplemented birds irrespective of the inclusion levels during the heat stress. Abdominal fat was significantly decreased in TAN5 and TAN7.5 levels; however, muscle histological features were significantly higher in all treatment groups.

“…Dietary Tau is a sulfur-containing amino acid with vari ous biological functions, such as membrane stabilization, bile acid conjugation, vitagene activation, anti-inflammation, and immune stimulation in animals [ 18 , 19 ]. Dietary supplementation of 0.5% to 1.0% Tau has been reported to restore heat stress-induced growth impairments and physiological dysfunctions in broiler chickens [ 17 , 18 , 44 ].…”

Objective: The objective of the present study was to investigate the comparative effects of dietary functional nutrients including glutamine (Gln), chromium picolinate (Cr picolinate), vitamin C (Vit C), betaine (Bet), and taurine (Tau) on growth performance, meat quality, immune responses, and stress biomarkers in broiler chickens raised under heat stress conditions.Methods: A total of 420 21-d-old Ross 308 male broiler chickens (initial body weight = 866±61.9 g) were randomly allotted to 1 of 7 treatment groups with 6 replicates. One group was kept under thermoneutral conditions and was fed a basal diet (PC, positive control). Other 6 groups were exposed to a cyclic heat stress condition. One of the 6 groups was fed the basal diet (NC, negative control), whereas 5 other groups were fed the basal diet supplemented with 0.5% Gln, 500 ppb Cr picolinate, 250 mg/kg Vit C, 0.2% Bet, or 1.0% Tau. The diets and water were provided ad libitum for 21 d.Results: Broiler chickens in NC group had decreased (p<0.05) growth performance and immune responses measured based on cutaneous basophil hypersensitivity (CBH), but increased (p<0.05) stress responses measured based on feather corticosterone concentrations and blood heterophil:lymphocyte than those in PC group. However, none of dietary functional nutrients had a positive effect on growth performance of broiler chickens. Dietary supplementation of 250 mg/kg Vit C improved (p<0.05) CBH responses of broiler chickens, but other functional nutrients had no such an improvement in CBH responses. All functional nutrients decreased (p<0.05) stress responses of broiler chickens.Conclusion: Functional nutrients including Gln, Cr picolinate, Vit C, Bet, and Tau at the supplemental levels used in this study decrease stress responses of broiler chickens to a relatively similar extent. However, this reduction in stress responses could not fully ameliorate decreased productive performance of broiler chickens raised under the current heat stress conditions.

This study was conducted to investigate the effect of taurine as a prophylactic treatment on antioxidant function and inflammatory responses of broilers challenged with lipopolysaccharide (LPS). A total of 256 one-day-old male Arbor Acres broiler chicks were randomly assigned to 4 treatments with 8 replicates of 8 birds (8 birds/cage). Four treatment groups were designated as follows: 1) in the CON group, broilers fed a basal diet; 2) in the LPS group, LPS-challenged broilers fed a basal diet; 3) in the LPS + T1 group, LPS-challenged broilers fed a basal diet supplemented with 5.0 g/kg taurine; and 4) in the LPS + T2 group, LPS-challenged broilers fed a basal diet supplemented with 7.5 g/kg taurine. The LPS-challenged broilers were intraperitoneally injected with 1 mg/kg body weight (BW) of LPS at 16, 18, and 20 d of age, whereas the CON group received an injection of sterile saline. The results showed that broilers injected with LPS exhibited decreased (P < 0.05) the average daily gain (ADG) and the 21 d body weight (P < 0.05), while taurine supplementation alleviated the negative effects of LPS. Additionally, the LPS-induced increases (P < 0.05) in serum alanine transaminase and aspartate transaminase activities were reversed by taurine supplementation. The taurines could alleviate the hepatic oxidative stress, with the presence of lower content of malondialdehyde (P < 0.05), higher content of glutathione (P < 0.05), and an increased glutathione peroxidase (GSH-Px) activity (P < 0.05). The concentrations of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in the liver were measured by ELISA kits, and the result showed that dietary taurine supplementation prevented these cytokines increases in the liver of LPS-induced broilers. Taurine reduced the genes expression of IL-1β, TNF-α, IL-6, cyclooxygenase-2 and inducible nitric oxide synthase, whereas it boosted the expression levels of antioxidant-related genes (nuclear factor erythroid 2-related factor 2, heme oxygenase-1, glutamate-cysteine ligase catalytic subunit, and GSH-Px) in the liver of LPS-induced broilers. In conclusion, dietary taurine supplementation in broilers mitigated LPS-induced defect in ADG, oxidative stress and inflammatory responses.
