Effects of Dietary L-Glutamine or L-Glutamine Plus L-Glutamic Acid Supplementation Programs on the Performance and Breast Meat Yield Uniformity of 42-d-Old Broilers

Abstract: This study aimed at evaluating four dietary L-Glutamine (L-Gln) or L-Gln plus L-Glutamate (L-Glu) supplementation programs on the performance, breast yield, and uniformity of broilers. A total of 2,112 one-d-old male Cobb 500 ® broilers were distributed according to a randomized block design in a 2 × 4 factorial arrangement (L-Gln or L-Gln plus L-Glu × 4 supplementation programs), totaling eight treatments with 12 replicates of 22 broilers each. The supplementation programs consisted of the dietary inclusion o… Show more

“…Glutamine dietary supplementation decreases health problems, prevents intestinal atrophy, maintains antioxidant status, decreases incidence of diarrhea, resulting in increased weight gain and improved efficiency (Haynes et al, 2009;Zhong et al, 2011;Wang et al, 2014;Watford, 2015). Similar results have also been reported in broiler chicken (Nassiri Moghaddam and Alizadeh-Ghamsari, 2013;Jazideh et al, 2014;Nascimento et al, 2014;Manvailer et al, 2015;Muro et al, 2015;Olubodun et al, 2015;Ribeiro Jr et al, 2015;Luquetti et al, 2016;Maiorka et al, 2016;Namroud et al, 2017).…”

“…Se ejecutaron dos meta-análisis a partir de un total de 22 artículos científicos (1814 animales). (Avellaneda et al, 2008;Ayazi, 2014;Bartell & Batal, 2007;Dai et al, 2009;Dai et al, 2011;Fasina et al, 2010;Hu et al, 2016;Jazideh et al, 2014;Luquetti et al, 2016;Maiorka et al, 2016;Manvailer et al, 2015;Murakami et al, 2007;Muro et al, 2015;Mussini et al, 2012;Namroud et al, 2017;Nascimento et al, 2014;Nassiri Moghaddam & Alizadeh-Ghamsari, 2013;Olubodun et al, 2015;Ribeiro et al, 2015;Sakamoto et al, 2011;Soltan, 2009;Zavarize et al, 2011). Para explicar la heterogeneidad entre los estudios se realizaron meta-regresiones utilizando como covariables: nivel de inclusión de Gln (%), edad de inicio de suplementación (días), edad de evaluación (días), duración de la suplementación (días), número de repeticiones por tratamiento, número de pollos muestreados por unidad experimental (repetición), nivel de lisina (%) y proteína cruda en la dieta (%).…”

“…Several studies reported a positive impact of AA supplementation on performance, e.g. threonine (Thr) [6][7][8], arginine (Arg) [9][10][11], but also the non-essential amino acid glutamine (Gln) [12][13][14]. However, AA supplementation to an IP formulated baseline would not be expected to improve performance but result in excess AA intake.…”
