“…The different types of soybean processing confer different nutritional characteristics for birds, especially with respect to amino acid digestibility, since lysine, threonine, and methionine are especially sensitive to dry heating (Café et al, 2000) and mainly in the metabolizable energy contents of the extruded soybeans (Freitas et al, 2005). Large variations in nutritional values have been described for extruded soybeans (Costa et al, 2013), mainly due to the lack of standardization in the thermal processing used by the manufacturers (Nunes et al, 2015).…”

Two experiments were conducted to evaluate the apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), and standardized ileal amino acid digestibility coefficient (SIDC) of extruded soybean cake (ESC) at four different extrusion temperatures: 90, 100, 110, and 120 °C. In experiment 1, 300 male broilers were randomly distributed into four treatments (600 g kg −1 reference diet + 400 g kg −1 of SBC at different extrusion temperatures) + reference diet, with six replicates of 10 birds. A metabolic assay using the total excreta collection method was performed from 14 to 23 days to determine AME and AMEn. Quadractic effect of the extrusion temperature was observed, with the maximum AMEn value estimated as 3424.99 kcal kg −1 for 105.58 °C. In experiment 2, 300 male broilers were randomly distributed into four treatments (453 g kg −1 protein free diet + 547 g kg −1 SBC at different extrusion temperatures) + protein free diet, with six replicates of 10 birds. Experimental diets were offered from 16 to 21 days, and at 21days, birds were sacrificed by cervical dislocation for collection of the ileal digesta to determine the SIDC of ESC. The best SIDC values for lysine (0.824%), methionine (0.908%), and cysteine (0.741%) were estimated at 117.72, 114.40, and 107.37 °C, respectively. The other amino acids evaluated showed a linear response, with better SIDC values with increasing extrusion temperatures. The extrusion temperatures affect metabolizable energy and amino acid digestibility of soybean cake for broilers, being important the standardization of extrusion temperature to maximize the nutritional value of soybean cake used in broiler diets.

The objective of this study was to evaluate the inclusion of protease and sugarcane yeast in poultry diets on performance, organ weight, intestinal biometry, chemical composition and deposition of body nutrients in the 1 to 7-day old phase. The experimental design consisted of a randomized complete block design, in a factorial arrangement of 2 (without and with the enzyme protease) x3 (yeast levels: 0, 6 and 12%) +1 (positive control diet), totaling seven treatments with five replicates, birds per experimental unit. The treatments used consisted of a positive control diet and the others were the negative control, with reductions in nutritional levels of protein and amino acids by 4% requirement. In the negative control diets, protease enzyme was included in three levels of sugarcane yeast. In isolation, treatments with or without inclusion of protease influenced the chemical composition of the birds. The levels of yeast from sugarcane yeast presented effects for weight gain, feed conversion, moisture and crude protein in the nutrient deposition. The inclusion of protease in diets for broiler chicks cannot remedy the poor performance provided by the use of sugarcane yeast, in addition to presenting lower levels of deposition of body nutrients.

The objective was to determine the values of apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen balance (AMEn) of roasted and in natura amaranth grains. A breeding stock of 108 female Japanese quails (Coturnix coturnix japonica) with an initial age of 29 days was used. The birds were distributed in a completely randomized design with three treatments and six replications, with six quails per experimental unit. The treatments used were reference diet, reference diet + 30% in natura amaranth and reference diet + 30% roasted amaranth. The variables evaluated were feed intake, body weight variation, retained nitrogen, retained crude protein, dry matter digestibility and crude protein. Higher values of AME and AMEn were verified for the roasted amaranth grains, in relation to the in natura grains. There was no verification regarding the influence of amaranth grains, both roasted and in natura, for the variables feed intake, body weight variation, retained nitrogen, retained crude protein, dry matter and crude protein digestibility. It was concluded that the in natura amaranth grains provided 3888 kcal/ kg of AME and 3352 kcal/kg of AMEn, while the roasted amaranth grains provided 4044 kcal/kg of AME and 4028 kcal/kg of AMEn.
