“…When Arg was added back to the Arg deficient low CP diet, weight gain, feed efficiency, breast meat yield, and breast meat Cr concentration increased, abdominal fat pad decreased and became comparable to the normal CP treatment. Some of these results are in line with the recent findings ( Dilger et al., 2013 ; Dao et al., 2021 ) and highlight the importance of supplemental Arg in a low CP diet fed to broilers as described above. Although the addition of Arg to the Arg deficient low CP diet had no significant effect on wooden breast and white striping issues, Bodle et al.…”

“…During 10 to 42 d, the birds offered 15 g/kg low CP Arg deficient diet had 7.8% lower weight gain, 10 points higher FCR, 8.5% lower breast meat yield, 30.4% more abdominal fat pad and 27.2% lower Cr concentration in breast meat compared to those offered a normal CP diet. Some of these observations are in line with the recent findings ( Dilger et al., 2013 ; Castro et al., 2019 ; Dao et al., 2021 ) and highlight the negative effects of Arg deficiency in broilers. Arginine deficiency also increased breast meat pH which may favor microorganism growth and decrease the shelf life of breast meat.…”

“…First, the low CP diet already contained adequate levels of methyl donors (e.g., methionine and choline) and there was no need for additional methyl donors to convert dietary GAA into Cr. Second, the maximum level of GAA that was used in this study (i.e., 0.20%) was not high enough to saturate muscle tissues with Cr and to instigate any negative effects on performance as seen in the previous study ( Dao et al., 2021 ). Further research is warranted to determine the maximum level of GAA that can be used to spare Arg in low CP diets and the role of betaine in such cases should be explored.…”

“…A recent study ( Dao et al., 2021 ) showed that the response of broilers to supplemental GAA in Arg deficient low CP diet was minimal. This was possibly due to excessive dietary CP reduction, a high level of GAA supplementation, and insufficient methyl donors to convert GAA to Cr.…”

Guanidinoacetic acid ( GAA ) is the direct precursor of creatine and can spare arginine ( Arg ) for creatine synthesis in low crude protein ( CP ) broiler diets. This study aimed to determine the extent GAA could spare Arg in broilers offered low CP diets and if supplemental betaine provides additional benefits. Seven hundred twenty-day-old Ross 308 male broilers were assigned into 9 dietary treatments with 8 replicates of 10 birds each. The treatments were; normal CP diet, a low CP (−15 g/kg) diet deficient in Arg, a low CP diet sufficient in Arg, and low CP diets with GAA, where 0.1% added L-Arg was spared by GAA at 50, 100, and 150% with and without 0.1% betaine. The treatments were offered during grower (d 10–24) and finisher (d 25–42) phases. The birds offered a low CP Arg deficient diet had 7.8% lower weight gain, 10 points higher FCR, 8.5% lower breast meat yield, 27.2% lower breast meat creatine concentration and 30.4% more abdominal fat pad compared to those offered a normal CP diet. When Arg was added back to the Arg deficient diet, growth performance, breast meat yield and creatine concentration loss were restored. When GAA spared Arg at 150%, feed intake, weight gain, FCR, breast and abdominal fat yields, breast meat moisture, drip loss, and breast meat creatine concentration became comparable to Arg sufficient low CP and normal CP treatments. When GAA spared Arg at 100 and 50%, FCR was 3 and 5 points lower than the normal CP treatment. Breast meat creatine concentration was positively correlated to feed efficiency (r = 0.70, P < 0.001) and breast meat moisture (r = 0.33, P < 0.01), and negatively correlated to relative weight of abdominal fat (r = −0.37, P < 0.01) and breast meat pH (r = −0.49, P < 0.001). There were no benefits of adding betaine with GAA on the parameters measured but the results with GAA were consistent in the presence or absence of betaine.

“…In broilers, Cit has been shown to have Arg-sparing effects ( Klose and Almquist, 1940 ; Tamir and Ratner, 1963 ; Su and Austic, 1999 ); however, information on the effects of Cit supplementation on growth performance and other parameters is extremely limited. A recent study by Dao et al. (2020) indicated that supplementation of Cit to an Arg-deficient reduced protein diet for broilers resulted in similar growth performance, carcass, and bone traits compared to those fed the Arg-deficient reduced protein diet supplemented with Arg.…”

Effects of L-arginine and L-citrulline supplementation in reduced protein diets for broilers under normal and cyclic warm temperature

Heat stress causes significant economic losses in the broiler industry. Dietary supplementation of arginine (Arg) and citrulline (Cit) might increase the performance of broilers raised under warm temperature due to vasodilation effects. This study investigated the effects of L-Arg or L-Cit supplementation in broilers fed a reduced protein wheat-based diet deficient in Arg under thermoneutral (NT) and cyclic warm temperature (WT). Ross 308 cockerels ( n = 720) were randomly allocated to 4 dietary treatments with 12 replicates of 15 birds per pen from d 7 to 21. The 4 treatments were: normal protein (NP), i.e., 22.3% and 20.9% crude protein in grower and finisher, respectively; reduced protein (RP), i.e., 2.5% lower protein and deficient in Arg; and RP supplemented with 0.28% Arg (RP-Arg) or 0.28% Cit (RP-Cit). A factorial arrangement of treatments was applied during the finisher phase (21 to 35 d). Factors were: diet (4 diets above); and temperature, NT (24 °C) or cyclic WT (33 ± 1 °C for 6 h per day) with 6 replicate pens per treatment. During 7 to 35 d and 21 to 35 d, the birds fed the RP diet had lower body weight gain (BWG) and higher FCR compared to the NP diet ( P < 0.01). The addition of Arg or Cit to RP decreased FCR compared to RP ( P < 0.01). During 21 to 35 d, the birds exposed to WT had lower feed intake (FI), lower BWG ( P < 0.001) but similar FCR ( P > 0.05) compared to birds exposed to NT. Diet by temperature interactions were not observed for performance parameters during the period of WT ( P > 0.05). On d 35, the RP-fed birds had a lower yield of thigh and drumstick, higher fat pad, lower femur ash, and breaking strength but similar serum uric acid level and higher nitrogen digestibility on d 21 compared to those offered NP ( P < 0.05). Supplementation of Arg or Cit to RP resulted in increased femur ash on d 35 ( P < 0.05). Thus, feeding the NP diets is necessary to maintain growth performance in broilers regardless of the temperature conditions.
