“…Birds of the CMpredominant (T 2 ) diet groups consumed a significantly higher amount of feed than those fed the SBM-predominant (T 1 ) diets, regardless of enzyme supplementation. The results agree with the reports of previous studies (16,17,13). The reason for the greater feed consumption of broiler chickens on enzyme-supplemented diets may be a result of increased fiber digestion, as the fiber tends to create a gut fill.…”

“…Amino acid (e.g., lysine, threonine, valine, isoleucine, and leucine) digestibility was promoted in the birds fed the SBM (T 1 ) diet as compared to the CM (T 2 ) diet. The higher protein quality and quantity of soybean meal than that of canola meal may be responsible for the improved amino acid digestibility (13). Apart from this, as is evident from the formulation profile, the reduced fiber content of the soybean meal (T 1 ) diet may also be liable for creating the differences in digestibility of the two plant-based diets (22).…”

“…Inclusion of enzymes in plant diets enables the birds to degrade the antinutritive feed components along with promoting the breakdown of starch, cell walls, and storage proteins (10). However, many previous researchers have reported that the efficacy of such enzymes seems to be unpredictable in some cases and depends partially on the substrate or the nature of the diet composition including many other factors (11)(12)(13). The current study was undertaken to assess the relative nutritional merits of the two leading vegetable protein sources, SBM and CM, when fed with or without carbohydrase (Avizyme) and phytase enzyme supplements.…”

The study was undertaken to assess the quality of broiler meat via detection of heavy metal contents. Seven farms were selected randomly from the five divisions of Bangladesh. Broiler meat samples were collected during starting and growing phases of production stage from each of the farms by purchasing to detect the heavy metal contents i.e chromium (Cr) and cadmium (Cd) in this study. A total of 210 meat samples (105 starter and 105 grower) was collected from the selected farms and analyzed to determine the concentration of toxic metals (Cr, Cd) in meat samples. The heavy metal data (Cr, Cd) of broiler starter meat samples from laboratory analyses of five divisions of seven feed mills were unaffected (P>0.05) between treatment. The Cd contents of broiler grower meat samples of five divisions of seven farms together differed significantly (P<0.05) between treatment except for Cr. Significant variation (P<0.01) was observed in the various meat samples of broiler chicken by individual division (Dhaka, Chittagomg). It can be concluded that the quality of broiler meat of different farms appears to be good based on the chemical evaluation, even though variation was found in the toxic metal contents of meat samples. The analyzed concentration of toxic metals in meat samples were within the range or limits of the acceptable level, so no possibility of causing health hazard will create over the consumer world through after consumption of broiler meat.

The aim of this work was to study the continuous or intermittent impact of a multienzyme supplement on growth performance, nutrient digestibility, and blood metabolites of broilers, and to evaluate production index of dietary supplementation. A total of 315 unsexed day-old Arbor Acres broiler chicks were randomly distributed to seven treatments groups, keeping initial body weights similar, in 35-floor pens (replicates) of nine chicks per replicate (pen) and five experimental units per treatment. All experimental groups were fed the same basal diet and administered seven multienzyme treatments: the 1st group (control) did not receive any enzyme supplementation; the 2nd, 3rd, and 4th groups were administered multienzymes at 0.5, 1.0, and 1.5 mL/L drinking water, respectively. Each enzyme supplemented-group was divided into two subgroups, with additives being applied either continuously (24 h/day) or intermittently (12 h/day) from 1 to 35 days old. Regardless of administration method, multienzyme supplements at 1.0 mL/L water along with a corn-soybean meal diet increased the body weight gain (BWG) by 7.8% compared to 0.5 mL/L water during days 1–21 of age. In addition, 1.5 mL/L water significantly improved BWG by 5.1% of broilers compared to 0.5 mL/L water during days 1–35 of age. Enzyme supplementation at 1.5 mL/L water significantly enhanced feed conversion ratio (FCR) by 4.3% during days 1–21 of age, and FCR by 5.2% and European production index (EPI) by 10.4% during days 1–35 of age compared to the group on 0.5 mL/L water. For the whole period, there were improvements of beneficial consideration in BWG (4.0%), FCR (4.0%), and European production index (8.2%) due to continuous multienzyme supplementation at 0.5 mL/L water compared to the same dose added intermittently. A similar trend was observed due to intermittent multienzymes at 1 mL/L drinking water that resulted in increased BWG by (6.4%) and improved FCR by (6.7%) and EPI by (12.7%). Intermittent administration significantly increased feed intake of broilers during 22–35 days of age compared to continuous supplementation. Multienzymes at different doses did not significantly affect the digestibility of nutrients, blood serum biochemical constituent, inner body organs, and markers of functions of liver and renal organs. In conclusion, the highest BWG and the best FCR and EPI for the whole period were from broilers given continuous 1 and 1.5 mL/L drinking water or intermittent multienzyme supplementation at 1.5 mL/L drinking water. Furthermore, intermittent supplementation of enzymes at 1 mL/L drinking water and continuous supplementation at 0.5 mL/L drinking water can be investigated in further experiments as a tool to improve broiler growth performance and economic traits and to decrease the cost of enzyme application.
