“…In contrast to these results, Café et al (2002) reported that birds fed the diets supplemented with Avizyme had a significantly (P ≤ 0.03) higher proportion of abdominal fat at 42 days and 49 days. Although, results from some previous studies showed that carcass yields and internal organs were not affected due to addition of enzyme to diets of broiler chickens (Biswas et al 1999;Kidd et al 2001;Hassan et al 2011).…”

A 4 × 3 factorial experiment was designed to study the effects of a multi-enzyme (Avizyme 1502; combination of xylanase, α-amylase and protease) in three levels (0, 250, 500 mg/kg) on performance and carcass characteristics of broiler chickens fed corn-soybean meal diets with different levels of metabolizable energy (ME; 13.18; 12.34; 11.93 and 11.51 MJ/kg) from 1 to 49 days of age. Results showed that dietary treatments had no significant effect (P > 0.05) on feed intake at 10 days and 24 days but birds fed diets containing 13.18 MJ/kg ME with 500 mg/kg multi-enzyme consumed more feed than birds fed diets with 11.51 MJ/kg ME and 250 mg/kg multi-enzyme (P < 0.05) at 49 days. Average daily gain in starter (1-10 days) and finisher (25-49 days) periods was affected by interaction between ME and enzyme. No significant differences (P > 0.05) were observed for feed conversion ratio (FCR) in grower period, although dietary treatments affected FCR in starter and finisher phases. At 49 days of age, the best FCR obtained for birds fed diets containing 13.18 MJ/kg ME and 250 mg/kg multi-enzyme. The highest FCR was for birds fed a diet with 11.51 MJ/kg ME with 250 mg/kg multi-enzyme. Breast, thigh and liver were significantly affected by dietary treatments. A diet with 13.18 MJ/kg ME and 500 mg/kg multi-enzyme resulted in the highest breast and thigh yield (P < 0.05). It can be concluded that adding enzymes to corn-soy based diets allowed the reduction in the energy level of broiler diets without any negative effects on performance of broiler chickens.

“…Zou reported that the supplementation with 0.025%, 0.05% and 0.075% Hemicell in a corn-SBM diet improved ( P <0.05) weight gain respectively by 3.52%, 5.06% and 5.39% at 22-42d and by 2.86%, 4.64% and 3.18% at 0-42d, F/G for the 0.025% and 0.05% groups was significantly better than the control group at 22-42d (3.72% and 4.96%) and 0-42d (2.14% and 5.07%)[14]. Kidd reported that the addition of 112 g/t enzyme preparation, the active ingredient was α -galactosidase, in corn-SBM diet decreased F/G by 8.4% at 0–7 wk [15], while the addition of 115 g/t decreased F/G by 2.2% at 0–7 wk [16]. In present study, the addition of BM or AG improved F/G at 0-21d (by 6.1% and 5.4%), 22-42d (by 7.1% and 10.0%) and 0-42d (by 6.3% and 8.1%) in NC diet but not in PC diet (except for BM at 0-21d).…”

The study was conducted to compare the effects of XG with AG and BM at different metabolizable energy diets on growth performance, digestive physiology and energy utilization of broilers fed with corn-SBM diet. A 2 × 4 factorial design was used with two basal diets (the positive control group, PC; negative control with ME reduction 100 kcal/kg, NC) and with or without the addition of three exogenous enzymes (0.02% BM; 0.01% AG; 0.05% XG) respectively. 1,200 one-day-old broilers were randomly allocated to 8 treatments with 10 pens of 15 broilers. There was no significant difference on BW, BWG, and FI at 0-21d, 21-42d or 0-42d for diet, enzymes or their interactions, but FI at 22-42d and 0-42d were tend to be decreased with the addition of enzymes. The F/G was significantly improved by the addition of enzymes especially in NC diet. The dietary AME and TME in PC or NC diet were significantly increased by XG or AG in NC diet. The villus length and V/C of ileum were significantly increased by the addition of BM or XG. XG improved the activities of trypsin, chymotrypsin and amylase, BM improved the activity of trypsin at 21d, and AG improved the activity of chymotrypsin at 21d. Comparing to PC diet, the addition of enzymes in PC or NC diet decreased feed cost per kg body weight gain especially in NC diet (except AG in PC diet) with the highest profits for XG in NC diet. In conclusion, supplementation of 0.02% BM or 0.01% AG or 0.05% XG could improve feed conversion of broilers in corn-soybean meal diet by improving energy utilization and digestive physiology, and also supplementation of 0.05% XG had a preferable efficacy in low energy diet.

“…Besides, type of feeding regimen (restricted) had effect. It can also be attributed to limiting nutrients (Kidd et al, 2001;Café et al, 2002) as portrayed by the lowest daily weight gain of T2.…”

The performance of F1 piglets fed fermented or enzyme-supplemented cassava peels was investigated. Peels from freshly harvested cassava were fermented for four days, sun-dried for 3-5 days, then milled. The cassava peel meal (CPM) replaced maize in grower and finisher diets in T1 (control), T2 (fermented CPM) and T3 (fermented CPM + maxigrain R enzyme) in a completely randomized design. The diets were served at 4% of live body weights daily to 27 Largewhite x Duroc weaner-gilts, aged 8 weeks and weighing 10.61±0.27 kg. The piglets suckled until mid-lactation, then shared finishing diets with the sows in addition. Data was analyzed with one-way ANOVA on SPSS. Average litter sizes, average birth weights, average weaning body weights and mortality rates had no significant (p>0.05) differences. Average daily body weight gains differed significantly (p<0.05) 155.24±0.09g (T1) and 159.29±0.15g (T3) compared to 146.67±0.11g (T2). Fermented cassava peels with or without enzyme supplementation has no deleterious effect on the performance of F1 piglets.
