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: This experiment was conducted to evaluate the effect of growth promoter additives an alternative to antibiotics on performance, intestinal morphology and on microbiota of 21-to-35-day-old piglets. A total of 160 commercial crossbred piglets (males and females) with initial weight of 6.10±0.709kg were allotted in a completely randomized design with five treatments: Basal diet - Negative Control (NC); Basal diet + antibiotic (PC); Basal diet + mannanoligosaccharides (MOS); Basal diet + organic acids (OA), Basal diet + mannanoligosacharides + organic acids (MOS+OA), eight replicates and four piglets per experimental unit. The inclusion of additives in the diets had no effect (P>0.05) on the final average weight of piglets. Similarly, no effects (P<0.05) were observed on average daily feed intake and on average daily weight gain. The feed conversion improved (P<0.01) with the inclusion of additives in the diets compared to piglets fed with the NC. There was no effect (P>0.05) of the dietary additives on intestinal morphology and microbiota composition (enterobacteria and lactobacilli). Use of antibiotics, prebiotics, organic acids or prebiotics associated with organic acids in the diet improves feed conversion of piglets from 21 to 35 days of age. The additives have no major effects on piglets’ intestinal morphology and microbiota.

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 production performance of broilers with the addition of ginger (Zingiber officinale) in broiler diets in starter phases. Were used 630 broiler chicks in a completely randomized design with five treatments and seven repetitions with eighteen birds each. The treatments consist of a reference diet with corn and soybean meal and adding different levels of powdered ginger, five treatments, consisting of positive control, negative control and three levels of ginger (0.50%, 0.75%; 1.0%). Were evaluated at the end of each phase, feed intake, weight gain, feed conversion, body weight, pancreatic weight and length and weight of the intestine. The data will be submitted to analysis of variance and means to regression analysis with 5% significance. No effects of the treatments on the performance variables were observed in the initial stage of creation. With this result, at twenty-one days old, we observed the potential for substitution of growth promoters for powdered ginger. The inclusion of up to 1% of powdered ginger did not affect bird performance providing results similar to positive control treatments with growth promoter.

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.

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.

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.

This study aimed to evaluate the use of wattle tannin as an adsorbent of toxic metals in broilers fed on diets with different levels of replacement of limestone with golden mussel meal. First, we conducted a trial to evaluate the performance of broiler chicks from 1 to 21 days old when fed on wattle tannin. For this we used 720 male broiler chicks that were one day old, in a completely randomized design with six treatments and six replications. The treatments were composed of basal diets with increasing levels of wattle tannin (0, 250, 500, 750, 1000 and 1250 g tonne-1), where the tannin replaced the inert material of the feed. All of the diets were isonutritive and isocaloric. The results showed that 250 g tonne-1 of tannin was detrimental to weight gain, final weight and feed conversion, and the use of 1000 g tonne-1 of wattle tannin, in addition to these effects, caused a drop in consumption of the ration. There was no effect of treatment on morphometric measurements of villi, crypt or the villus:crypt ratio. Next, we conducted a second test to evaluate the performance of broiler chicks from 1 to 21 days of age when fed with increasing levels of replacement (0, 25, 50, 75, 100%) of limestone with golden mussel and even supplementation or not wattle tannin. Five repetitions were used and the birds were housed in a completely randomized design. In diets with the inclusion of tannin, 250 g tonne-1 of wattle tannin was used, which replaced the inert material in the feed. In this test, 1200 male broiler chicks that were one day old were used. The results showed that the golden mussel contains large quantities of calcium, with low concentrations of toxic metals and microbiological contamination within the allowed range. Performance data show that mussel can be used to replace up to 100% of limestone in feed without affecting the variables, but the use of 250 g tonne-1 of wattle tannin affects the performance of chicks. Bone quality was not changed by the treatments. Phosphorus and calcium in the bones remained stable during treatment and only the gray variation showed interaction effects from the use of mussel and wattle tannin.
