The effects of enzyme supplementation on the performance, yield, and blood profile of broilers fed corn and soybean diets from 1 to 42 days of age were evaluated. A total of 960 male broilers were used, distributed in a completely randomized design, with six treatments and eight replications. Two diets were used: a positive control formulated to meet the birds’ nutritional requirements (Diet 1) and a negative control diet with reduction of 150 kcal.kg-1 of metabolizable energy (Diet 2) and 12% amino acid in the initial phase and 18% during the growing and finishing phases. Further diets were based on the negative control with enzymes: enzyme complex 1, composed of 125 g ton-1 protease; enzyme complex 2, composed of 100 g ton-1 amylase, protease, and xylanase; enzyme complex 3, composed of 500 g ton-1 amylase, protease, and xylanase; and enzyme complex 4, composed of 125 g ton-1 protease and 500 g ton-1 beta-mannanase. Enzymatic supplementation did not improve performance during the initial and growing phases due to nutritional imbalance, resulting in the worst weight gain and feed conversion during the finishing phase. Carcass yield, leg yield, abdominal fat, and pancreas were altered by enzymatic supplementation. Triglyceride levels influenced abdominal fat deposition, and the serum levels of albumin and alanine aminotransferase were altered by enzymatic supplementation. Enzymatic supplementation was not effective in restoring broiler performance, carcass yield, and cuts, with changes in the serum biochemical profile of the broiler chickens.

Here we tested how feeding with exogenous enzymes affects the performance, carcass yield, and ileal digestibility in broilers from 21- to 42-days-old. The study included 1008 male broilers randomly distributed into six diets: positive control (PC), corn and soybean meal containing all the nutritional requirements; negative control (NC), with a 120 kcal.kg-1 reduction in metabolizable energy relative to the PC; enzyme complex one (NC + 100 ppm of endo-1,4-beta-xylanase); enzyme complex two (NC + 200 ppm of xylanase, amylase and protease); enzyme blend one (NC + 100 FXU kg-1 of xylanase and 200 FXU kg-1 of amylase); and enzyme blend two (NC + 100 FXU kg-1 of xylanase and 300 FXU kg-1 of amylase). The enzyme complex two (CN + 100 FXU.kg de xilanase e 300 FXU.kg de amilase) and enzyme blend two (NC + 100 FXU kg-1 of xylanase and 300 FXU kg-1 of amylase) had greater weight gain, feed conversion, carcass yield, and digestibility of nutrients than the NC (P < 0,05). We found that enzyme complex two and enzyme blend two valued their nutritional matrix promoting better performance and digestibility of broilers.

ABSTRACT The objective of this study was to evaluate the use of an enzyme complex-α-amylase, ß-glucanase, phytase, cellulase, xylanase and protease-in the feed of swine in growing and finishing phases, by assessing their performance (daily weight gain, daily feed intake, and feed conversion), dry matter, crude protein, and crude energy apparent digestibility, and the feed costs. Eighty pigs-castrated males, and females-of approximately 63 days of age and initial weight of 20.18±1.98 kg were distributed in a 5×2 factorial arrangement (diet × sex), in a randomized block design, with eight replications. The treatments used were: positive control diet consisted of 3,300 kcal/kg in the growth-I phase, and 3,250 kcal/kg in the growth-II and finishing phases; negative control diet with energy reduction of 85 kcal/kg of metabolizable energy (ME) (NC85); NC85 diet with addition of enzyme complex (EC85); negative control diet with energy reduction of 100 kcal/kg ME (NC100); NC100 diet with addition of enzyme complex (EC100). The addition of the enzyme complex to the diet with energy reduction of 100 kcal/kg ME increased the digestible protein content of the diet for the swine in the growth-II phase. The addition of the enzyme complex to the diet with energy reduction of 85 and 100 kcal/kg ME increased the digestible energy content of the diets for the swine in the finishing phase. The use of enzyme complex in diets with reduction of 85 kcal/kg ME for male swine in growing and finishing phases is recommended for improving feed conversion and economic efficiency during the growth-I phase. The use of enzyme complex is not justified for female swine.

Two experiments were conducted to assess the use, in broiler diets, of full-fat canola and flax seed or their restored mixtures of seed meals and oils. The first experiment compared raw and heated full-fat canola and flax seeds, and mixtures of the meals with the corresponding oils or animal tallow (ratios of 6:4, respectively), each added at 10% to the diet. The second experiment evaluated the raw full-fat seeds or mixtures of the meals with canola oil or animal tallow, added at 10 and 20% to the diets. Each experiment lasted 6 wk. Heat treatment did not significantly affect performance (P > 0.05). Dry matter and protein retention, and bird mortality were not influenced by dietary treatments. Diets containing 10 or 20% full-fat canola or canola meal plus oil mixtures resulted in similar body weight, feed conversion and carcass yield as the soybean meal control diet. In the first experiment, the inclusion of full-fat flaxseed depressed body weight, feed conversion and dietary metabolizable energy (ME) while the flax meal plus flax oil containing diets gave responses similar to the canola meal diets. In exp. 2, increasing the level of flax seed or flax meal plus oil mixture to 20% further depressed body weight and feed conversion. The ME and feed conversion efficiency of birds fed the full-fat seed containing diets were less than those obtained from birds fed the meal plus oil diets, but only significantly so for the flax diets. The type of fat fed with the meal had no effects on the responses of the birds. Key words: Chickens, canola, flax, heating, carcass yield, protein retention, metabolizable energy

The aim of this study was to evaluate the effect of dietary metabolizable energy levels on the performance and carcass yield of free-range broiler chickens from 1 to 84 days of age. A total of 900 male day-old naked neck lineage chicks were distributed in a completely randomized design between six levels of metabolizable energy (2,700; 2,800; 2,900; 3,000; 3,100 and 3,200 kcal.kg-1 diet) with six replications of 25 birds each. The increase in levels of dietary metabolizable energy resulted in a linear reduction of the feed intake, crude protein and digestible lysine intakes, as well as in the protein body deposition and protein efficiency and linear improvements in the feed conversion ratio of chickens in all experimental phases. The carcass yield, wing and abdominal fat weight and percentage of abdominal fat reduced linearly by increasing the level of dietary metabolizable energy. The diet including 2700 kcal.kg-1 of metabolizable energy in the diet of free-range broiler chickens in phases 1 to 28, 28 and 56 and 57 to 84 days of age does not interfere in the broilers performance and results in a better carcass yield in the final period of production.

Abstract. The effect of different phytases on the performance response, nutrient utilization and tibia characteristics of chickens was investigated. The five pelleted diets were the following: positive control (PC) with added monocalcium phosphate; negative control (NC) formulated with equivalency values of phytase for Ca and digestible P; and three further diets where different phytases were individually added to the NC diet at 500 FTU/kg. The phytases were derived either from Aspergillus (phytase I), or E. coli (phytases II and III). Compared to PC, the performance parameters, as well as apparent metabolizable energy (AMEn), mineral retention, bone breaking force and tibia mineral content were suppressed by the reduction of dietary Ca and digestible P. All phytases enhanced the overall body weight gains and feed conversion ratio in comparison with NC, but none outperformed PC. Only phytase II improved AMEn compared to NC and PC group. However only phytase I outperformed NC group in terms of mineral retention and P retention was higher than phytase II and III. No significant differences were observed in fat digestibility and N retention. Bone strength among phytases did not differ and all improved this parameter compared to the NC diet. However, even though all phytases enhanced tibia minerals content, the improvement was less pronounced with phytase III. Moreover, the differences in all analysed tibia minerals between phytase III and II were significant suggesting that even among 6-phytases derived from and expressed in the same organism, different efficacy or mode of action can occur.

The residue originated from antibiotics and hormones had been thought to carry out adverse effects for the human who consume meat processed from the broilers treated by antibiotic feed additive. For this reason, using an alternative additive such as probiotic might produce healthier meat. The objective of the recent study was to evaluate administering different levels of probiotic yakult + tape yeast (YTy) into the mixing of rice bran + corn bran (RCB) to replace 30% of the commercial diet to carcass yield and abdominal fat of broilers. As many as 100 broiler chicks, Cobb strain, were reared up to 5 weeks in this study. The study was designed into a Completely Randomized Design with subsampling consisted of 5 treatments, 4 replications, and 2 sub samples. Broiler commercial diet with the market code of CP 511 Hi-provite manufactured by PT Charoen Pokphand was used for a positive control diet (P0+). The RCB feeds were mixed with 0, 10, 20, and 30 ml/kg of probiotic YTy then being used to replace 30% of the commercial diet to build experimental diets P0-, P1, P2, and P3, respectively. The results of the recent study indicated that administering 10‒30 ml/kg of probiotic YTy highly significantly (P<0.01) increased the weights of the whole carcass and carcass parts. The percentages of whole carcasses among P1, P2, and P3, however, were not statistically different. The percentage of the breast significantly (P<0.05) increased while the percentage of the back significantly (P<0.05) decreased. Although statistically not significant differences, the abdominal fat percentage tended to decline. In conclusion, administering a probiotic YTy in the diet increased the percentage of the whole carcass and tended to reduce the abdominal fat of the broiler.

A total of 200 Cobb 500 male broilers were randomly allocated to 4 treatments consisting of 5 replications with 10 chicks each in order to evaluate the effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population. Treatments were control diet (T1), control diet with 1% thyme seed powder (T2), control diet with 1% garlic powder (T3) and control diet with 0.5% thyme seed and 0.5% garlic powder (T4). Feed intake, body weight, weight gain, feed conversion ratio (FCR), carcass yield was not significantly (p>0.05) improved by dietary treatments compared to control. Escherichia coli (E. coli) count in the gut of broilers did not show significant difference among dietary treatments. However, Lactobacilli count in the gut of broilers significantly (p<0.05) increased in T2 compared to that of T1. Lactobacilli count in the gut of broilers received T1, T3 and T4 did not differ significantly (p>0.05) with each other. It was concluded that thyme seed was reliable as feed additive in the broiler diet and could provide positive advantages to the colonization and proliferation of Lactobacilli.

Although phytase has been researched, new enzymes have been produced, leading to different animal responses. In this scenario, the present study proposes to evaluate the inclusion of a bacterial phytase produced by Escherichia coli in broiler diets based on corn and soybean meal, with or without nutrient reductions, on the performance, nutrient digestibility, phosphorus bioavailability, and bone minerals of those animals and on the economic viability of this practice. A total of 896 male broiler chickens were distributed into 32 experimental units, each housing 28 broilers. The experiment was set up as a completely randomized design with four treatments (Positive Control (PC)- diet meeting the nutritional requirements of the broiler chickens; Negative Control (NC) with reductions of 100kcal/kg of ME, 0.14% avP and 0.11% tCa; NC + phytase (500 FTU/kg); PC + phytase (500FTU/kg)) and 8 replicates. Phytase increased (p < 0.05) feed intake and body weight gain and improved feed conversion ratio in starter (1 to 21 days) and total (1 to 42 days) phases, respectively, compared with Negative Control diet without supplementation. The Negative Control + phytase diet also led to a feed intake similar to Positive Control in the starter and total phases. The inclusion of phytase without nutrient reductions improved (p < 0.05) feed conversion ratio in the starter phase, compared to Positive Control diet. There was an increase (p < 0.05) in the digestibility of dry matter, crude protein and phosphorus and in apparent digestible energy in the Negative Control + phytase diet compared to the Negative Control diet. Phytase supplementation increased (p < 0.05) the digestibility of crude protein, calcium and phosphorus, and apparent digestible energy compared to Positive Control diet. Ash, phosphorus, and calcium contents were higher in the Negative Control + phytase diet compared with those observed in the Negative Control diet without enzyme (p < 0.05). The Positive Control + phytase diet provided higher ash contents (p < 0.05), but calcium and phosphorus deposition was similar to those obtained with Positive Control diet. Phytase inclusion allows for a reduction in the diet cost per ton of produced feed. In conclusion, dietary supplementation with bacterial phytase produced from Escherichia coli for broiler chickens is recommended, as it provided increases in production performance, nutrient digestibility, and energy metabolizability and a reduction in the diet cost.

ABSTRACT An experiment was conducted to evaluate broiler chicken performance and carcass yield in response to carbohydrase supplementation (Xylanase and Betaglucanase; XB) and association of carbohydrase and phytase (PHY). A total of 1,920 day-old male broiler chicks (Cobb 500) were distributed in a completely randomized design with 8 treatments and 8 replicates each, allocated in 64 pens with 30 chicks each. The treatments were: Positive Control (PC); Negative Control (NC): reduced ME [-120kcal/kg (Starter) and -170kcal/kg (Finisher)]; NC + XB [50g/ton]; NC + XB [100g/ton]; NC + XB [150g/ton]; NC + XB [50g/ton] + PHY [100g/ton]; NC + XB [100g/ton] + PHY [100g/ton]; NC + XB [150g/ton] + PHY [100g/ton]. The inclusion of XB (150) and XB (50, 100, and 150) associated with phytase increased feed intake than positive control when considering the total rearing phase. The feed conversion ratio of all broilers fed diets with energy reduction were worse than positive control, even with the addition of enzymes, and did not differ between them. There was no significant effect of treatments on carcass parameters.
