“…Corzo & Kidd (2003) recommended even lower levels, 1.15% for live weight gain and 1.28% for feed conversion at the 1 to 18-day age; however, the live weight gain of the birds was very low, around 50% the value obtained in the present result. Atencio et al (2004) did not observe any effect on feed intake; nevertheless, the live weight gain and feed conversion varied quadratically with digestible Arg levels between 1.10 and 1.39% in the 1 to 21-day period.…”

The effects of starter diet (days 1 to 21) supplemented with arginine (Arg) on the production performance and duodenum and jejunum mucosa morphometry of broilers were studied. Male Cobb broiler chickens (990) were randomly assigned to one of ϐive treatments in a complete random design. Measurements of 33 chicks per treatment were made in six repetitions. The treatments consisted of a basal diet with 1.390% digestible Arg (no supplementation) and four dietary levels (1.490%, 1.590%, 1.690%, and 1.790%), providing a relationship with lysine of 1.103; 1.183; 1.262; 1.341 and 1.421%, respectively. From the age of 22 days on, all birds received conventional grower diet. The data were submitted to regression analysis by polynomial decomposition of the degrees of freedom in relation to the levels of Arg. The Arg supplementation increased (P<0.05) the live weight and the feed conversion ratio without increasing the feed intake of the birds. However, no effect was observed (P>0.05) in the growth phase (days 22 to 42) in the absence of the Arg supplementation. The supplementation of Arg over of NRC recommendation during the starter phase may be necessary for the expression of the maximal weight gain potential in birds. No effect (P<0.05) of Arg dietary supplementation was observed either on small intestine weight and length at any age. However, the duodenum villus:crypt ratio increased and the crypt depth decreased in the ϐirst week in response to increasing dietary Arg. It is concluded that broiler Arg dietary supplementation in the starter diet improved production performance and small intestine morphometry, especially in the ϐirst week.

“…In studies with broilers (Costa et al 2001;Atencio et al, 2004) found no influence of arginine levels on the performance of growing birds. However, Brake et al (1998), also working with broilers, observed improved feed conversion linearly with increasing the arginine/lysine ratio Table 4 -Arginine/lysine ratio in the diet on the parameters of egg quality from 1.05 to 1.49 in the diet, at a temperature of 31 ºC; this result indicates that high temperatures require high ratios of arginine/lysine in the diet.…”

To determine the relationship of arginine with lysine for Japanese quails during the period of production, an experiment was conducted using 360 subspecies of Japanese quails (Coturnix coturnix japonica) with 162 days of age, distributed in a completely randomized design. Diets were formulated with corn, soybean meal, sorghum and wheat bran containing 20.0% crude protein and 2,800 kcal ME/kg. The basal diet contained suboptimal level of lysine equal to 1% and was supplemented with five levels of L-arginine 99% (0.032; 0.083; 0.134; 0.185 and 0.236%) to replace the glutamic acid, corresponding to the relationship of arginine with digestible lysine of 1.16, 1.21, 1.26, 1.31 and 1.36. The parameters studied were: feed intake, egg production per hen/day, egg production per hen housed, commercial egg production, egg weight, egg mass, feed conversion by egg mass, feed conversion per dozen eggs, weight and percentage of components of the eggs (yolk, albumen and shell) and specific gravity. There was no significant effect on the relationship of arginine with digestible lysine in the diet of Japanese quails for any of the parameters examined. The arginine/lysine ratio of 1.16, which corresponds to a daily intake of 288.84 mg of arginine, provides satisfactory performance and egg quality of Japanese quails

“…The use of methionine, L-lysine and L-threonine in broiler feed is well established, while other amino acids as tryptophan and arginine are generally considered as the next limiting amino acids in broiler feed. The arginine (Arg) is a 'next limiting' amino acid due its antagonism with lysine (Lys) and if Lys was added to a diet, also the requirements of Arg increases (Jones et al 1967;Austic & Scott 1975) and this can affect broiler performance (Balnave & Barke 2002;Atencio et al 2004) and muscle development (Fernandes et al 2009). Tryptophan, apart from being a structural component of all protein is a precursor of serotonin and melatonin, regulating the broiler circadian rhythm and thus feed intake and growth (Emadi et al 2011).…”

The study investigated the effect of low-crude protein (CP), essential aminoacids (EAAs) and conjugated linoleic acid (CLA) on broiler growth performance. From 1 to 6 days of age, 196 male broiler chicks fed the same basal diet containing 22.5% of crude protein. From 7-28 days the chicks were assigned to 7 treatments (4 replicates, 7 birds/replicate). The control group fed a 21.5% CP diet, supplemented with DL-methionine (Met) and L-lysine (Lys). The low-CP diet (19% CP) was supplemented with Met þ Lys (2EAAs group) or with Met, Lys, L-arginine, L-tryptophan and L-threonine (5EAAs group); 2EAAs and 5EAAs groups were also supplemented with 0, 2 or 4% CLA. The body weight gain (BWG) was the biggest (p < .01) in the control group; 2EAAs and 2EAAs 4% CLA groups had lower BWG than the three groups fed 5EAAs diets. Diet 5EAAs þ2% CLA induced lower (p < .01) feed conversion ratio (FCR) than 5EAAs þ4% CLA and also showed the lowest (p < .01) protein intake. Reducing CP in broiler diet increased (p < .01) the digestibility of CP. The total protein content of plasma was greater (p < .01) in 2EAAs þ4%CLA and 5EAAs þ4%CLA than in the control. Decreasing the protein content of the diet from 21.5 to 19.0% penalised the growth performance of broilers from 7 to 28 days of age and the administration of CLA at 2 or 4% was not able to support growth. However, addition of 5EAAs without or with 2 or 4% of CLA resulted in recovery of FCR and PCR.ARTICLE HISTORY
