“…The results, a positive effect of Lys and ME on nitrogen balance was found out. The results of N retention obtained are consistent with the findings of Kim et al (2014) and Chalova et al (2016) that increasing dietary amino acid supplement could reduce nitrogen excreted resulted in increase of nitrogen retention. Nitrogen balance and nitrogen retention mostly shows the consumption of protein by body, if the energy in the diet is sufficient and protein is low, the N excretion will be decreased (Zhao et al, 2019).…”

A 3x2 factorial arrangement was used in the study to evaluate the apparent nutrient and amino acid digestibility of local Muscovy ducks in two periods. Two factors of the trial were dietary lysine levels (0.8%, 1.0% and 1.2%) and metabolizable energy (ME) levels (12.55MJ/kg DM and 12.97MJ/kg DM) for 8-week-old period; and dietary lysine levels (0.7%; 0.9%; 1.1%), and ME levels (13.39MJ/kg DM; 13.81 MJ/kg DM) for 10-week-old period. There were three replications and four ducks per experimental unit. The findings indicated that the apparent nutrient digestibility coefficients of DM, OM, and EE were significantly higher for the Lys 1.2 and Lys 1.1 treatments in both periods (P<0.05). At 8-week-old period, the digestibility results of lysine, and valine in the Lys 1.2 treatment; and of isoleucine, leucine, phenylalanine in the ME 12.97 treatment were significantly (P<0.05) higher than those of the other treatments. At 10-week-old period, the Lys 1.1 and ME 13.81 treatments had some better essential amino acid digestibility values, particularly, arginine, isoleucine, lysine; and methionine isoleucine, lysine, methionine, and threonine (P<0.05). Additionally, nitrogen retention in the Lys 1.2 and Lys 1.1 treatments (for 8 and 10-week-old periods) were significantly (P<0.05) higher than the other treatments. It could be concluded that Local Muscovy ducks at 8 weeks and 10 weeks of age, the appropriate diets contained 1.2% lysine and 12.97 MJ ME/kg DM, and 1.1% lysine and 13.81 MJ ME/kg DM, respectively.

“…These results are in agreement with several studies reporting that low-protein amino acid-supplemented diets had no negative effect on broiler performance, while reducing nitrogen excretion by 33.6% [ 24 , 43 , 52 , 54 , 55 ]. The reduction of nitrogen excretion also influences ammonia volatilization in poultry houses: supplementing amino acids in low-protein diets reduced ammonia volatilization by 45% in poultry [ 4 , 5 , 56 ].…”

“…Decreasing dietary protein levels of broiler diets could be a good strategy, but the amino acid requirements for broiler chicks must be satisfied by supplementing synthetic amino acids to the basal diets. In this way it is possible to achieve several goals: (1) minimize the excess of amino acid input and thus nitrogen pollution; (2) improve the bird tolerance to hot climate; (3) obtain satisfactory growth performance; all this can increase the profit for the poultry industry [ 3 , 4 , 5 ].…”

“…Environmental pollution due to nitrogen excretion is an important issue in poultry houses and results in negative impacts on the health of workers and birds, soil, and ground water [ 4 , 5 ]. Thus, reducing dietary protein levels with proper amino acid supplementation has been of great interest [ 2 , 4 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

The objective of this study was to evaluate the effect of low-protein diets with amino acid supplementation on growth performance, carcass yield, meat quality and nitrogen excretion of broilers raised under hot climate conditions during the finisher period. In trial 1, broilers from 28 to 49 days of age were fed 18% crude protein (CP) as a positive control or 15% CP supplemented with (1) DL-methionine (Met) + L-lysine (Lys), (2) Met + Lys + L-Arginine (Arg), or (3) Met + Lys + L-Valine (Val). In trial 2, broilers from 30 to 45 days of age, were fed an 18% CP diet as a positive control or 15% CP supplemented with Met, Lys, Arg, Val, L-Isoleucine (Ile) or combination with glycine (Gly) and/or urea as nitrogen sources: (1) Met + Lys, (2) Met + Lys + Arg, (3) Met + Lys + Val, (4) Met + Lys + Ile, (5) Met + Lys + Arg +Val + Ile + Gly, and (6) Met+ Lys + Arg + Val + Ile + Gly + urea. Protein use was improved by feeding low-protein amino acid-supplemented diets as compared to the high-protein diet. Feeding 15% crude protein diet supplemented with only methionine and lysine had no negative effects on carcass yield, CP, total lipids and moisture% of breast meat while decreasing nitrogen excretion by 21%.

“…Dietary protein is a major contributing factor in driving feed cost. Reducing the crude protein level in the broiler diet has recently attracted much attention since it could reduce the feed cost and nitrogen excretion [ 7 , 8 ]. The previous study demonstrated the inclusion of PFA stimulated the nutrient digestibility and small intestine villus height of broilers fed a corn soybean diet [ 4 ], however, it remains unknown for the effects of PFA in a low protein diet, and there might be an interaction between PFA and crude protein level.…”

The aim of this experiment was to evaluate the effect of a phytogenic feed additive (PFA) on growth performance and nutrient digestibility of broilers fed corn and soybean meal-based diets containing two different levels of crude protein. A 2 × 2 completely randomized factorial arrangement (eight replicates/treatment, 30 birds/replicate) was conducted with a positive control (PC) and negative control (NC) containing crude protein at standard or reduced by 1.5% (equivalent to a reduction of 15 g/kg), respectively, and supplementation of PFA at 0 or 125 ppm of diet. There were no significant interactions found between PFA and CP levels in the current study. Main effect analysis showed that during 0–42 d of age NC diets decreased body weight gain (p < 0.05), but increased feed intake (p < 0.05) and feed conversion ratio (FCR, p < 0.01), whereas supplementation of PFA resulted in a lower FCR (p < 0.01). The ileal nutrient digestibility was reduced (p < 0.05) in the broilers fed a reduced protein diet at 21 d compared to the standard protein level group, but there were no effects for PFA levels. Similarly, supplementing PFAs showed no effects on digestive enzyme (Alkaline phosphatase, amylase, and lipase) activity in jejunal digesta and jejunal brush border enzyme (maltase, sucrase, and aminopeptidase) activity. Supplementation of PFA downregulated (p < 0.05) the mRNA expressions of cytochrome P450 1A and interleukin 6 in the ileum but had no effects on nutrient transporter genes in the jejunum. In conclusion, supplementation of PFA reduced broiler FCR during the whole grow-out period and positively regulated the immune responses in the ileum.
