“…This increase is usually in the range of 50–150 kcal/kg feed depending on the nature and quality of the ingredients used in the diet and the nature of the used enzyme [ 29 ]. NSP-degrading enzymes can reduce the increase in the viscosity of digesta resulting from sugars leaking from the grain cell walls by releasing the nutrients trapped in the feed cellular matrix [ 30 ] because the viscosity is larger in smaller birds and decreases with age.…”

Background The aim of this study is to investigate whether the energy matrix values of the nonstarch polysaccharide- (NSP-) degrading enzymes, bioemulsifier (LYSOFORTE®), guanidinoacetic acid (CreAMINO®), or their combinations could be summed. The effects of these additives on the growth performance, carcass traits, and economic value of the broiler chicken diets were evaluated. A total of 525-one-day-old Ross chicks with an initial body weight of 42.96 ± 0.87 g were haphazardly allocated into seven groups with five replicates. The seven experimental treatments are as follows: (1) basal diet with no additives (breeder recommendation), which is the control group, (2) basal diet minus 100 kcal/kg supplemented with 0.02% NSP-degrading enzymes (NSP), (3) basal diet minus 50 kcal/kg supplemented with 0.025% emulsifier (LYSOFORTE®), (4) basal diet minus 50 kcal/kg supplemented with 0.06% guanidinoacetic acid (CreAMINO®), (5) basal diet minus 150 kcal/kg supplemented with a mixture of NSP and LYSOFORTE® (NSPL), (6) basal diet minus 100 kcal/kg supplemented with a mixture of NSP and CreAMINO® (NSPC), and (7) basal diet minus 200 kcal/kg supplemented with a mixture of NSP, LYSO, and CreAMINO® (NSPLC). The experiment lasted for 35 days. Results It was found that the final body weight, body weight gain, and relative growth rate were significantly higher in birds fed diets supplemented with NSPL, NSPC, CreAMINO, and LYSO with the reduced energy matrix value. The overall feed conversion ratio was significantly improved due to the supplementation of NSPC, CreAMINO, NSPL, and LYSO with the reduced energy matrix value compared to the control group. Moreover, no significant effect on the carcass criteria was observed by the different treatments. As a result of the dietary supplementation with NSPL, NSPC, CreAMINO®, and LYSO with the reduced energy matrix value, the net profit, total return, economic efficiency, and performance index were increased and the cost of feed per kg of body weight gain was decreased. Conclusion The energy matrix value of NSPL, NSPC, CreAMINO®, and LYSOFORTE could be established in the diets of broiler chickens to improve the growth performance and economic efficiency.

“…However, Attia et al (2014) found that the addition of multiple enzymes increased the percentage of carcass weight and total edible parts of broiler chickens. The increase in the percentage of carcass weight was due to a decrease in the inedible parts of broiler chickens and the weight of the small intestine (Moftakharzadeh et al, 2017).…”

“…The results of these studies indicated that the addition of both individual enzymes or multiple enzymes in feed-based rations containing a high quantity of non-starch polysaccharides had a positive effect on the duck performance, as was reported by some researchers on broiler chickens (Akyurek et al, 2009;Gitoee et al, 2014;Goli & Shahryar, 2015;Moss et al, 2017;Teymouri et al, 2018;Effiong et al, 2019). The improvement in performance was thought to be due to an increase in the digestibility of food substances, including crude protein, crude fiber, and ash (minerals) (Kang et al, 2013;Zeng et al, 2015;Moss et al, 2017;Effiong et al, 2019) and a decrease in the viscosity of gastrointestinal digesta (Moftakharzadeh et al, 2017;Teymouri et al, 2018).…”

The objective of this study was to determine the effect of varying levels of cattle rumen fluid obtained from abattoirs as sources of a crude enzyme on growth performances and carcass characteristics of Kerinci ducks fed rations based on local feed ingredients. The research was carried out using 140 one-week-old male Kerinci ducks. The experiment used a randomized block design consisted of 5 treatments, each with 4 replicate groups and was blocked based on body weight, while each cage unit consisted of 7 ducks. The treatments applied were R1= 0 mL RFS/kg ration (control), R2= R1 + 22 mL RFS/kg ration, R3= R1 + 44 mL RFS/kg ration, R4= R1 + 66 mL RFS/kg ration, and R5= R1 + 88 mL RFS/kg ration. The experimental ducks were fed the experimental ration for 7 weeks and fed ad libitum according to the treatment. At the end of the 7th weeks of treatment, two ducks from each cage were slaughtered and utilized for analysis of carcass and digestive organs parameters. The results showed that the addition of RFS up to a level of 88 mL/kg ration had no significant effect (p>0.05) on feed consumption, feed conversion, carcass weight, and digestive-organ weight. Still, it had significant effects on body weight gain and final body weight. The highest body weight gain and final body weight were achieved with the addition of RFS at the level of 88 mL/kg ration. It can be concluded that the addition of cattle rumen-fluid supernatant as a source of crude enzymes at the level of 88 mL/kg ration improved the growth performance of local Kerinci ducks.

“…Interestingly, in their study addition of phytase as only enzyme increased heat loss of broilers. While viscous grains such as wheat or barley increase the relative size and length of gastrointestinal tract of broiler chickens (Fan, Han, Xu, Wang, & Shi, 2009;Moftakharzadeh et al, 2017), addition of enzyme to NSP containing diets in many studies has reduced relative weight of these energetically active organs (Rodríguez et al, 2012;Wang, Qiao, Lu, & Li, 2005). One possible reason for lower HP in enzyme treatments would be lower maintenance of digestive active organs induced by enzyme supplementation.…”

“…Anti-nutritional compounds known as non-starch polysaccharides (NSPs) are the most important factor has confined feeding wheat to broiler chickens especially at early days of growing period. The presence of soluble NSP can cause highly viscous conditions in the gastrointestinal tract and decrease contact between digestive enzymes and substrates, resulting in poor nutrient digestion and performance broiler chickens (Choct, Sinlae, Al-Jassim, & Pettersson, 2006;Moftakharzadeh, Moravej, & Shivazad, 2017;Nian, Guo, Ru, Li, & Peron, 2011). Supplementation of wheat-based diet with exogenous glycanase appear to enhance growth performance and energy utilization alongside with (Hashemipour, Khaksar, Rubio, Veldkamp, & Van Krimpen, 2016;Kiarie, Romero, & Ravindran, 2014;Pirgozliev et al, 2015;Wu, Choct, Wu, Liu, & Swick, 2017) or without reduction of intestinal viscosity of broilers (Amerah, Ravindran, Lentle, & Thomas, 2008).…”

An experiment was carried out to investigate the effect of multi-enzyme in high and low levels of metabolizable energy (13.81 and 11.51 MJ kg -1 diet) on performance and energy utilization of broilers fed wheat-soybean meal diets from 0 to 21 days of age. Result showed that birds fed diets containing 11.51 MJ kg -1 consumed significantly (p < 0.05) more feed than diets containing 13.81 MJ kg -1 , whereas daily gain and feed conversion ratio improved (p < 0.05) when enzyme was added to 11.51 MJ kg -1 diet. There was significant improvement in metabolizable energy, net energy for production, organic and dry matter digestibility in 0-21 when diets supplemented with enzyme (p < 0.05). Addition of enzyme to 11.51 MJ kg -1 containing diet significantly (p < 0.05) reduced heat production of birds in 0-10 d, whereas heat production was not changed in 21 days. Supplementation of 11.51 MJ kg -1 diet with enzyme improved the efficiency of ME use for carcass energy and protein retention of broilers (p < 0.05). Generally, the results of current study demonstrated that addition of enzyme to wheat-soybean diets improved NEp of broiler chickens while MEI was not changed and it seems NEp is a more sensitive energy utilization response criterion to use in evaluating broilers response to enzyme supplementation.
