A series of experiments was conducted to determine the nutritive value of wheat screenings, bakery by-products and wheat mill run used by the feed industry in Canada and to investigate the effect of enzyme supplementation on available energy content, nutrient digestibility and broiler chicken growth performance. Broiler chicken performance (2-wk growth trial) was compared using a wheat/soybean meal-based control diet and diets substituted with wheat by-products (wheat screenings, 200 g kg-1; bakery by-products or mill run, 100 g kg-1). In addition, diets containing one sample of each of the by-products were fed to broiler chickens with enzyme supplementation (Superzyme W®). Chicken performance was not affected by dietary substitution of wheat by-products for wheat as values for control, wheat screenings (three samples), bakery by-products (two samples) and mill run (one sample) were similar for body weight gain (514, 520, 515, 500 g bird-1) and for feed to gain ratio (1.52, 1.52, 1.52, 1.50), respectively. Response to enzyme supplementation was highest for wheat screenings showing a statistically significant (P ≤ 0.05) improvement in body weight gain (523 vs. 548 g bird-1) and feed to gain ratio (1.54 vs. 1.47). To further substantiate the importance of enzyme supplementation, a long-term production trial with broiler chickens was conducted. Five replicate pens of 60 birds per treatment were used in the starter (21 d) and grower (16 d) phases of the experiment consisting of three treatments: positive control (PC) (wheat/soybean meal/fish meal), negative control (NC) (wheat/wheat screenings/barley/soybean/ canola meal) and NC + Enzyme (Superzyme W®). In comparison to PC, the NC diet contained 5% less metabolizable energy, 8–10% less crude protein, amino acids and calcium and 25% less available phosphorus. Body weight gain and feed conversion ratio averaged 2.14, 2.10, 2.17 kg bird-1 and 1.68, 1.76, 1.66 for PC, NC and NC + Enzyme, respectively. A significant (P < 0.05) improvement in broiler chicken performance with enzyme supplementation was further substantiated by the same magnitude of difference in dry matter (71.2, 68.7, 75.1%), starch (92.5, 90.3, 95.6%), non-starch poly saccharides (NSP) (4.8, 15.0, 36.1%), energy (AME) (12.37, 11.83, 12.84 MJ kg-1) and phytate (44.3, 37.5, 69.5%) digestibilities. It is evident from this study that the use of wheat by-products in concert with an effective enzyme supplement in broiler chicken diets will allow for optimum growth performance.

Objective: To evaluate calcium stearoyl-2 lactylate (CSL) performance as an exogenous emulsifier together with lipase for broiler diets.Methods: In total, 252 one-day-old Ross 308 broiler chickens were allocated in a completely randomized design to give 6 replications per treatment with 7 birds in each cage. There were six dietary treatments representing a 2×3 factorial arrangement consisted of two energy levels (standard energy [positive control, PC] and –100 kcal/kg of the requirement level [negative control, NC]) and three dietary treatments (without additives [CON], CON+CSL [CSL], and CON+CSL+lipase [CSL-Lipase]). Corn and soybean meal-based experimental diets containing vegetable oil were formulated. Growth performance, blood parameters, visceral organ weights, ileal morphology, nutrient digestibility, and cytokine gene expression were measured.Results: Birds fed a diet including CSL increased (p<0.05) lipase level in blood compared to birds fed a diet including CSL-Lipase on day 21. Similarly, higher (p<0.05) liver weight was observed in birds fed a diet including either CSL or CSL-Lipase on day 21. Birds fed NC diet with CSL improved (p<0.05) nutrient digestibility compared to the NC diet on day 21. However, birds fed a diet supplemented with CSL or CSL-Lipase did not affect (p>0.05) the weight gain, feed efficiency, ileal morphology, and cytokine concentrations during the experiment period, regardless of dietary energy levels.Conclusion: Our results indicated that CSL has a role in improving nutrient digestibility in young birds when supplemented to a corn-soybean meal based broiler diet.

Abstract A 16-wk growth trial was conducted to examine the effects of dietary replacement of fish meal by defatted soybean meal (SBM) and fermented soybean meal (FSBM) with taurine supplementation on growth performance, nutrient apparent digestibility coefficient (ADC) and biological parameters of pompano fish. The FSBM was produced by fermenting SBM with Lactobacillus spp. Seven isonitrogenous and isoenergetic diets were formulated to replace 35% or 50% of fish meal by SBM or FSBM with taurine supplementation. The diets are denoted as follows: FM, SBM35, SBM35T, FSBM35T, SBM50, SBM50T, and FSBM50T. The FM (the basal diet) contained fish meal as a main source of dietary protein. Taurine was supplemented to SBM35T, FSBM35T, SBM50T, and FSBM50T at the level of 15 g/kg diet. Pompano juveniles with an initial body weight (BW) of 80 g reared in floating net cages were fed the experimental diets twice daily for 16 wk. Results showed that the final BW, weight gain, and feed conversion ratio of fish fed SBM35 and SBM50 were significantly lower than those of fish fed FM (P &lt; 0.05), indicating that the replacement of fish meal by SBM at the rate of 35% in the diet is excessive for pompano. Supplementation of taurine to the SBM-included diets significantly increased growth performance and feed utilization (P &lt; 0.05); however, these diets did not restore the performance back to a level equivalent to that of fish offered the basal diet. Meanwhile, fish fed FSBM35T had comparable growth and feed performances to those fed FM. Hematocrit values, total biliary bile acid levels, whole body lipid contents, and tissue taurine concentrations of fish fed SBM35 and SBM50 were the lowest among the treatments, but these parameters were improved by taurine supplementation and FSBM inclusion in the diet. Taurine supplementation increased lipid ADC, and SBM fermentation slightly enhanced both lipid and protein ADCs of the fish. These findings suggest that the combination of FSBM and taurine supplementation is an effective way to improve growth performance, nutrient digestibility, and biological parameters, and that FSBM with taurine supplementation can replace 35% of fish meal in pompano diets without any negative effects on growth and feed performances in a long-term feeding period.

This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.
