“…These fermentation products were, however, not increased in broilers fed the RSM diets in the present study. Other factors such as the presence of antinutritional factors, glucosinolates, tannins, phytic acid, and sinapine may have resulted in the poor performance of broilers fed the RSM diets (Khajali and Slominski, 2012 ; Rutkowski et al., 2012 ; Ahmed et al., 2014 ). Reduced villus height, deeper crypts, and lower VCR in broilers fed RSM diets compared with those fed the SBM diet may be due to the aforementioned antinutritional factors.…”

An experiment with 288 male (Ross 308) 1-d-old broilers was conducted to test the hypothesis that a coarse diet supplemented with butyric acid (BA) and fermentable carbohydrates (FC) improves performance of broilers with a poorly digestible protein source. The interaction effects of diet structure (fine or coarse), FC supplementation (with or without), and BA supplementation (with or without) in a poorly digestible diet based on rapeseed meal (RSM) were tested in a factorial arrangement of 8 (2 × 2 × 2) dietary treatments. The coarseness of the diet affected feed intake (FI) (P < 0.001), BW gain (P = 0.001), and the feed conversion ratio (FCR) (P = 0.001) positively. Broilers fed the coarse diets had, on average, 14% heavier gizzards and 11, 7, 5, and 6% lower relative empty weights of the crop, duodenum, jejunum, and ileum, respectively, compared with those fed the fine diets. Dietary coarseness resulted in, on average, 6% greater ileal protein digestibility, 20% lower gizzard pH, 19% greater villus height, 18% lower crypt depth, and 23% reduced cecal branched chain fatty acids (BCFA) compared with chickens fed the fine diets. Broilers fed BA-supplemented diets had an improved FCR (P = 0.004) and decreased crypt depth (P < 0.001) compared with those fed diets without BA. Fermentable carbohydrate supplementation did not influence growth performance, gut development, or contents of total BCFA and total biogenic amines in the cecal digesta (P > 0.05). Supplementation with FC, however, decreased the cecal concentration of spermine by approximately 31% compared with broilers fed diets without FC (P = 0.002). In conclusion, feeding a coarse diet supplemented with BA improved performance of broilers fed a diet containing a poorly digestible protein source. The negative effects of a poorly digestible protein source can thus be partly counterbalanced by coarse grinding and BA supplementation in the diet.

“…All birds were allowed a 4-day adaptation period where they were fed a corn-soybean based diet with 30% CM (basal diet, Table 1) (Soleimani et al, 2010). Two experimental diets containing either CM or fermented CM (FCM) as the sole source of energy and protein were prepared (Table 1) (Ahmed et al, 2014;Jia et al, 2012). Both diets contained titanium dioxide (0.5%) as an indigestible marker.…”

The aim of the current study was to investigate the potential of Lactobacillus salivarius solid state fermentation for reduction of glucosinolate content in canola meal (CM) as well as the improvement of its nutrient digestibility for broiler chickens. Canola meal was treated with the L. salivarius in solid state fermentation for 30 days. Nutrients ileal digestibility was tested using 42-day-old broilers fed by either CM or fermented CM (FCM) as the sole source of energy and protein. The results showed that fermentation of CM using L. salivarius reduced glucosinolate content of CM by 38%. The digestibility coefficient was improved significantly for crude protein, Met, Cys, Arg, Asp, Glu, and Ser in FCM compared to CM. However, apparent metabolisable energy of CM was not affected by fermentation. It appears that fermentation treatment of CM using L. salivarius may improve the overall nutritive value of CM for broiler chickens, reducing its total glucosinolate and crude fibre content by 38 and 16%, respectively.

“…Prior to diet formulation, representative samples from the corn and soybean were analysed for CP using Kjeldahl method according to the procedure of AOAC (1990) content using high performance liquid chromatography (HPLC) as described previously (Ahmed et al, 2014) (Table 2). Briefly, 0.1 to 0.2 g of sample was hydrolysed by 5 mL of 6N HCL at 110°C for 24 h. Afterwards, a 4 mL of internal standard (L--amino-N-butyric acid; AABA) was added to the hydrolysate (analysis of all AA except Met, Cys, and Trp).…”

A three-week trial was carried out to evaluate the effect of nonessential amino acids (NEAA) supplementation to a low-crude protein (CP) diet with adequate essential amino acids (EAA) level on growth performance, blood metabolites, and relative weights of abdominal fat, breast yield, and internal organs in broiler chickens raised under tropical hot and humid environment. Five isocaloric (3000 metabolisable energy/kg) corn-soybean diets were administered (1 to 21 days) to 5 groups of broilers (60 birds/group) as follows: i) 22.2% CP (positive control; PC); ii) 16.2% CP+all EAA to meet or exceed the National Research Council (1994) recommendations (negative control; NC); iii) NC+further EAA to equal the levels in the PC diet; iv) NC+NEAA to equal the levels in the PC; v) NC+EAA and NEAA to equal the amino acids levels in the PC diet. The results showed that the fortification of EAA alone, only improved feed intake (FI), whereas, addition of NEAA or EAA+NEAA significantly enhanced body weight, daily weight gain, and FI and decreased the feed conversion ratio to the same levels as in PC. Serum uric acid was significantly reduced and serum triglyceride increased in NC group. Dietary treatments had no significant effect on relative weights of heart, liver, abdominal fat, breast meat yield, serum albumin, and serum total protein. In conclusion, these results suggest that NEAA fortification may improve the growth performance of broilers fed an excessive low-CP diet under tropical hot and humid condition.
