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. Energia metabolizável e aminoácidos digestíveis de coprodutos de trigo e de farinhas de origem animal em dietas para frangos de corte
ABSTRACT The objective of this study was to determine the metabolizable energy, standardized ileal amino acid digestibility (SIAAD) and digestible amino acid values of wheat meal (WM), wheat gluten meal (WGM), meat bone meal (MBM) and poultry-by-product meal (PPM) in diets for broilers. In the first experiment, the total excreta collection method was used, w

3. Performance and Egg Quality of Commercial Laying Hens Fed Diets Formulated Using Non-Linear Programming
ABSTRACT Feed formulation using linear programming consists of determining the mixture of feedstuffs required to meet pre-established animal nutritional requirements at the lowest cost. On the other hand, with the use of non-linear programming, it is possible to define nutritional requirements at the time of formulation, aiming at maximum profit. The objecti

4. Lipid Sources in Diets for Hy-Line White Laying: Performance, Biometrics of Digestive Organs, and Bone Characteristics
ABSTRACT Dietary inclusion of lipid sources has been one of the methods adopted by nutritionists aiming at better energy balancing. However, alternative energy feedstuffs have been sought in an attempt to reduce production costs. In this regard, lipid sources that can replace conventional ones, such as beef tallow, cottonseed oil, and sunflower oil have been

5. Fibrous feedstuffs for the nitrogen retention of growing pigs
RESUMO: O objetivo deste estudo foi medir o balanço de nitrogênio (N) de suínos alimentados com dietas limitantes em lisina contendo níveis práticos de inclusão de farelo de trigo (FT) ou casca de soja (CS). Foram utilizados 24 suínos machos castrados com peso médio inicial de 57,36±2,01 kg e 72,68±3,24 kg nos experimentos 1 e 2, respectivamente.

6. Metabolisable energy prediction in energy feedstuffs and evaluation of the stepwise validation procedure using bootstrapping
RESUMO A utilização de valores preditos de energia metabolizável aparente (EMA), obtidos a partir de equações de regressão, pode ser útil para instituições de pesquisa e indústrias de nutrição. Contudo, há a necessidade de validação em amostras independentes para assegurar que a equação de predição da EMA seja confiável. Neste estudo, for

7. Prediction equations for energy values of animal meals obtained using meta-analysis
ABSTRACT The objective of this study was to determine prediction equations to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) values of animal meals used in broiler diets through meta-analysis. A bibliographic review was undertaken with studies conducted in Brazil from 2000 to 2016 to catalogue information on AMEn values and the followin

8. Intake and digestion of non-traditional feedstuffs by farmed collared peccary (Mammalia, Tayassuidae)
ABSTRACT To assess the ability of the collared peccary ( Pecari tajacu ) to digest dietary fiber, four adult male collared peccaries were randomly assigned to a 4 × 4 Latin square design to determine the effects of feeding non-traditional feed ingredients, taken from palm trees with different levels of dietary fiber, on intake and coefficient of total tract

9. Apparent digestibility of conventional and alternative feedstuffs by hybrid tambacu juveniles
ABSTRACT The apparent digestibility coefficients (ADC’s) of dry matter (DM), crude protein (CP), and gross energy (GE) of conventional feedstuffs (cottonseed meal-CSM, soybean meal-SBM, wheat bran-WHB, corn-COR) and regional alternative feedstuffs (common bean residue meal-CBR, mesquite meal-MES, pasta by-product meal-PBM) were determined for hybrid juveni

10. Determination of Ochratoxin A Levels in Mixed Feed and Feed Stuffs Used in Some Laying Hens and Ruminant Enterprises of Sivas City
ABSTRACT Mycotoxins, which are produced by some fungi under improper storage conditions before or after harvesting in plant products, cause acute or chronic toxicities. Ochratoxin A (OA) which is also one of the harmful mycotoxins pose a threat to animal and human health. This study was carried out in order to determine OA levels in mixed feed and feedstuffs

11. Apparent digestibility coefficient of chickpea, maize, high-quality protein maize, and beans diets in juvenile and adult Nile tilapia ( Oreochromis niloticus )
ABSTRACT The objective of our study was to assess the apparent digestibility of plant ingredients in diets for juvenile (50 g) and adult (220 g) Nile tilapia (Oreochromis niloticus). Dietary dry matter and protein apparent digestibility coefficients of four plant-derived feedstuffs (chickpea, maize, high-quality maize protein, and beans) were tested. The bea

12. The Efficiency of AMEn and TMEn Utilization for NE in Broiler Diets
ABSTRACT The experiment was conducted to evaluate the feed intake, body weight gain, total energy (kJ), protein (g) intake, energy and protein efficiency ratio (EER, PER), net energy, and metabolic body weight, on two commercial broiler chickens (Arian and Ross 308 strains). Four treatmentsincluded diets formulated based onAMEn(kJ/g) Total Amino Acid (TAA) (
