The objective of this study was to evaluate the effect of adding different xylanase and ?-glucanase enzyme blends to maize- and soybean meal-based diets on performance and energy metabolizability in broilers. Two experiments were carried out with broilers of the COBB 500 strain. In the first experiment, 1960 chicks were assigned to a completely randomized design with a 2 × 3 + 1 factorial arrangement, totaling seven treatments, namely, T1- Positive control (PC); T2 - Negative control 1 (NC1; PC minus 200 kcal kg-1 ME); T3 - NC1 + Blend A; T4 - NC1 + Blend B; T5 - Negative control 2 (NC2; PC minus 167 kcal kg-1 ME and 5% amino acids); T6 - NC2 + Blend A; and T7 - NC2 + Blend B. Fourteen replicates were used per treatment and 20 birds per experimental unit. The parameters evaluated at 21 and 42 days of age were weight gain (WG), feed intake (FI) and feed conversion (FC). At 42 days, production efficiency index (PEI), viability and the yields of cuts were also calculated. Birds that received diets with a reduced nutritional value showed a reduction in WG and PEI and worsened FC as compared those of PC treatment (p < 0.05). However, the birds that consumed the NC2 diet with Blend B exhibited a similar WG to those in PC group (p > 0.05) from 1 to 21 days of life. For the yield of thigh + drumstick, the factors were statistically similar (p > 0.05) to those observed in the PC birds. In the second experiment, 432 fourteen-day-old chicks were distributed in a completely randomized design with seven treatments, with eight replicates per treatment and six birds per experimental unit. The apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) values were determined. Overall, the NC2 diet with Blend B provided the highest AME and AMEn values; however, NC1 with the same enzyme blend was the treatment which provided the lowest values. The addition of xylanase and ?-glucanase enzyme blends to maize- and soybean meal-based diets improves WG at 21 days as well as PEI in broilers; however, it does not influence the yield of cuts. Enzymes (Blend B) improve the energy metabolization of broiler diets with reduced energy and amino acid levels.

The objective of this study was to evaluate the effect of the inclusion of feather meal (FM) in diets supplemented with protease for meat-type quails, on performance from eight to 21 days and from eight to 35 days of age and on carcass yield cuts and economic profitability from eight to 35 days of age. A total of 360 male, meat-type quails, were allotted to a completely randomized design, in a factorial 3 x 3 arrangement (three diets and three FM levels of inclusion), with four replicates of 10 quails per experimental unit. The diets evaluated were positive control (PC) + 0% FM, PC + 5% FM, PC + 10% FM, negative control (NC) + 0% FM, NC + 5% FM, NC + 10% FM, NC + 0% FM + protease, NC + 5% FM + protease and NC + 10% FM + protease. The NC diet was formulated with a reduction in crude protein and amino acids, compared to the PC diet. There was an effect (p < 0.05) of the inclusion of FM in diets on feed intake, weight gain and feed conversion ratio, from eight to 21 and from eight to 35 days of age. There was a significant effect (p < 0.05) of FM inclusion on the live weight of 35-day-old quails. The inclusion of FM impairs meat-type quails’ performance at all ages evaluated. NC diets, with and without protease, worsen the performance of birds compared to PC diets. Better economic profitability is observed for up to 5% inclusion of feather meal in positive control diets.

Grains, brans, and vegetable meals may contain non-starch polysaccharides (NSP), which increases viscosity in the gastrointestinal tract (GIT) and interfere with the digestion and absorption of nutrients. This study aimed to evaluate the performance and determine the metabolizable energy of a sorghum-based broiler diet with and without the supplementation of an enzymatic complex. The experiments were conducted in a completely randomized design with 1200 chickens, using sorghum-based feed with and without the addition of 50 g of enzyme-CCE complex (?-glucanase and ?-xylanase), and with two levels of metabolizable energy (ME kg-1): ME; ME + CCE; reduced ME (-50 kcal kg-1); and reduced ME + CCE. The data were subjected to an analysis of variance and the means were compared using a Tukey’s test at the 5% significance level. At 42 and 47 days of age, the living weight of the birds fed with the reduced ME was low, while birds fed with reduced ME + CCE had the same weight as those fed with other energy diets (ME and ME + CCE). Feed conversion was poorest at 47 days of age for the birds on reduced ME diet. In the metabolic test (with fattening diets) to determine AME and AMEn, the reduced ME diet had the lowest result, confirming the effect of the addition of enzymes. The addition of CCE to sorghum-based diets provides enough enzymatic activity to increase the metabolizable energy of the diet (50 kcal of AME) and influence the growth performance of broilers at the slaughtering age.

This study aimed to determine the effect of using fermented pineapple peel in the ration containing medicinal weeds on broiler chicken performance. The experiment was designed into a completely randomized design (CRD) with five treatments and five replicates. Treatments consisted of P0 = 0% of fermented pineapple peels meal (FPPM) in ration containing 0% medicinal weed (MW), positive control). P1 = 0% of fermented pineapple peels meal (FPPM) in the ration containing 2 % medicinal weed (MW), negative control). P2 = 7.5% of FPPM in the ration containing 2 % medicinal weed (MW). P3 = 15% of FPPM in the ration containing 2 % medicinal weed (MW). P4 = 22,5% of FPPM in the ration containing 2 % medicinal weed (MW). Two hundred two days of male broiler chicken were used in this study and kept for 42 days. The parameters were feed consumption, average daily weight gain, feed conversion ratio, slaughter weight. The observed data were analyzed by statistical product and service solution (SPSS 16.0), and Duncan's multiple range test tested significant effects among treatments. Results showed that the fermented pineapple peel meal up to 15% with other medicinal weeds was not influenced the broiler chicken performance.

The study aimed to evaluate the effect of organic acids and the combination of organic acids and essential oils on performance of replacement pullets hens. 360 animals from Hy-Line Brown lineage with eight weeks of age were distributed in a completely randomized design with four treatments and ten replicates. The experiment lasted 63 days. The treatments (diets) were: Treatment 1 - negative control (no growth promoter); Treatment 2 - positive control (with growth promoter); Treatment 3 – basal ration + organic acids; Treatment 4 – basal ration + organic acids + essential oils. The variables evaluated were the initial and final weights, weight gain, accumulated consumption and feed conversion. There was no significant effect of treatment on any of the investigated parameters. It was concluded that the inclusion of organic acids or a combination of acids and essential oils do not affect the productive performance of replacement pullets.

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.

Slow Growing

The aim of this study was to evaluate the chemical composition, energy values and nutrient metabolizability coefficients of corn grown using different organic fertilizers and its use for feeding slow-growing broilers. Two experiments were conducted. In the first experiment, two hundred 21-day-old broilers were distributed in a completely randomized design, with five treatments and four replicates of 10 birds per experimental unit. The treatments were a control diet and four test diets (corn fertilized with crotalaria, corn fertilized with millet, corn fertilized with humus, and corn without fertilization), including corn at 30% in the control diet. The apparent metabolizable energy, apparent metabolizable energy corrected for nitrogen balance, and apparent metabolizability coefficients of dry matter, crude protein and gross energy were determined. In the performance trial, two hundred and fifty 1-day-old chicks were distributed in a completely randomized design into five treatments (T1 – control diet with commercial corn, T2 – corn without fertilization, T3 – corn fertilized with humus, T4 – corn fertilized with millet and T5 – corn fertilized with crotalaria) and five replicates of 10 birds per experimental unit. Weight gain, feed intake, feed conversion and final weight at 20 days were evaluated. The AME and AMEn values of corn fertilized with crotalaria, millet, humus and corn without fertilization were 3246 and 3239 kcal kg?1; 2965 and 2954 kcal kg?1; 2909 and 2877 kcal kg?1; and 3265 and 3201 kcal kg?1, respectively. The apparent metabolizable coefficients of DM, CP and GE were: 89.75%, 66.88% and 88.5% for corn fertilized with crotalaria; 84.38%, 58.73% and 81.4% for corn fertilized with millet; 80.38%, 53.45% and 78.95% for corn fertilized with humus; and 89.48%, 68.95% and 87.85% for corn without fertilization, respectively. Feeding broilers with corn cultivated with different fertilizers affected (P < 0.05) weight gain, feed intake, feed conversion and final weight. The treatments using corn fertilized with crotalaria, millet, humus and commercial corn did not differ, with better results in relation to corn crop cultivated without fertilization. The use of crotalaria and millet as a green manure, and humus derived from dairy manure are alternatives that can be used on corn crop as they resulted in grains with adequate nutritional composition, energy values and metabolizable coefficients for slow-growing broilers from 1 to 20 days of age.

Soy protein concentrate improves nutrient utilization and growth performance compared to soybean meal, and diets with a low crude protein (CP) level decreases diarrhoea. The objectives were to (1) test a low CP diet based on different soy products, and (2) to test a very-low CP diet (15.1%) with amino acids (AA) on diarrhoea and productivity. A total of 5,635 weaned pigs (~28 days), were assigned to five dietary treatments; PC (positive control): Standard CP levels (192, 189, 191 g/kg CP) with 2500 ppm ZnO; NC (negative control): Same as PC without ZnO; SP (Soy protein concentrate): Low CP levels (176, 174, 191 g/kg CP); SB (Soybean meal): Low CP levels (177, 176, 191 g/kg CP); and XLA (X-low CP + AA): Very low CP levels (154, 151, 191 g/kg CP) with AA. The PC and XLA diets reduced diarrhoea by 41 and 61%, respectively, compared to the NC group, while no difference between SB and SP were observed. The XLA diet reduced feed intake and daily gain compared with PC and NC, where SP, SB, and XLA had a poorer feed conversion compared with PC. Conclusively, the SP and SB low-protein diets did not reduce diarrhoea or growth performance, whereas the XLA diet decreased both diarrhoea and performance.
