1. Standardized ileal amino acid digestibility of plant-based feedstuffs and phytase supplementation in broiler chicken diets
RESUMO Objetivou-se determinar a digestibilidade ileal estandardizada dos aminoácidos (SIAAD) do farelo de soja (FS), milho + FS, trigo + FS e uma dieta livre de proteína (PFD) com fitase. Um total de 672 pintos machos (493±10g), Cobb 500, foi distribuído em um delineamento inteiramente ao acaso, com 12 tratamentos (PFD, PFD + FS, PFD + milho + FS e PFD

2. Micobiota produtora de fitase isolada de solo e serapilheira do Bioma Cerrado
Resumo Grande parte dos solos agricultáveis brasileiros apresenta deficiência de P, em função da maior parte deste elemento estar indisponível para a absorção pelas plantas. Neste contexto, a habilidade dos fungos filamentosos em solubilizar o P de várias fontes, sejam estas, insolúveis, orgânicas e/ou inorgânicas, tem sido considerada uma caracte

3. Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four

4. Effect of probiotic Lactobacillus reuteri XC1 coexpressing endoglucanase and phytase on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens
ABSTRACT This study investigated the effect of transformed Lactobacillys reuteri on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens. A total of 480 broilers were assigned to six treatment groups and fed a phosphorus-adequate diet, a phosphorus-deficient diet, or a phosphorus-deficient die

5. Growth performance and carcass yield of broiler chickens in response to carbohydrases and its association with phytase
RESUMO O experimento foi conduzido para avaliar o desempenho e o rendimento de carcaça de frangos de corte em resposta à suplementação de carboidrase (Xilanase e Betaglucanase; XB) e à associação de carboidrase com fitase (PHY). Um total de 1.920 frangos de corte, machos, com 1 dia de idade (Cobb 500), foram distribuídos em um delineamento experiment

6. Complexos enzimáticos sobre a energia metabolizável e digestibilidade dos nutrientes do milheto para frangos de corte
RESUMO Objetivou-se avaliar o efeito de complexos enzimáticos sobre a energia metabolizável e o coeficiente de digestibilidade de nutrientes do milheto para frangos de corte. Quinhentos e setenta e seis frangos machos foram distribuídos em 36 gaiolas, com três tratamentos: T1 - composição de milheto sem complexo enzimático; T2 - composição de milhet

7. The effect of dietary phytase and various available phosphorus levels on performance and egg quality in Japanese quail
RESUMO As aves possuem baixo aproveitamento do fósforo fítico das dietas, devido à falta de enzimas endógenas que consigam realizar a quebra e aproveitamento do mesmo. Objetivou-se no presente estudo avaliar a adição de fitase em dietas de codornas poedeiras. Foram utilizadas 80codornas, em delineamento experimental inteiramente casualizado composto po

8. Influence of dietary 1αlpha-hydroxycholecalciferol, individually or in combination with microbial phytase in calcium and phosphorus deficient diets on growth performance and tibia parameter of Japanese quails (Coturnix japonica)
ABSTRACT. The effect of 1α-OH-D3 in calcium-phosphorus (Ca-P) deficient diets on Japanese quail growth performance and tibia parameters was investigated. Eight-day-old (n = 160) newly hatched quails were weighed and randomly allocated to 20 groups, each with 4 replicate pens of 8 birds. Treatments were as follows: T1, Ca-P-adequate; T2, Ca-P-deficient; T3,

9. Supplementation of fungal and/or bacterial phytase in broiler diets formulated with reduced phosphorus level and different calcium contents
ABSTRACT The objective of the current study was to evaluate the effects of three calcium:available phosphorus (Ca:aP) ratios and different supplementation with phytases from different origins on performance and ash, Ca, and P contents in the tibia of broilers. A total of 900 male broilers (22 to 35 days old) were fed ten dietary treatments in a completely ra

10. Effects of Nutrient Density and exogenous enzymesin Starter Diet on Performance, Intestinal Microflora, Gut Morphology and Immune Response of Broiler Chickens
ABSTRACT A total of 810 one-day-old, straight-run broilers were used to evaluate the effects of dietary nutrient density and feed additives included in the starter diet on their performance, intestinal microbiota, gut morphology, and immune response. A 3×3 factorial arrangement with three nutrient densities (100, 103.75 and 107.5%, as recommended) and three

11. Enzyme complex supplementation in different nutrient levels diets on pigs feces excretion and anaerobic digestion
ABSTRACT This research aimed to evaluate enzyme supplementation in diets with different nutritional levels for pigs in their feces excretion and anaerobic digestion. Fifty four gilts were placed on diets formulated to achieve 100 or 95 or 90 % of a pig's nutrient requirements, with the addition of an enzyme complex containing amylase, β-glucanase, cellulase

12. Digestibility, Determination of Metabolizable Energy and Bone Mineralization of Broilers Fed with Nutritionally Valued Phytase
ABSTRACT The objective of this study was to evaluate the effect of using exoenzyme phytase in broiler's diets on digestibility of nutrients, feed energy and tibia bone mineralization. A completely randomized design was used, with the following treatments: sorghum with dicalcium phosphate (SDP), corn with dicalcium phosphate (CDP), sorghum with meat and bone
