1. 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) (

2. Caracterização da equideocultura no estado de Minas Gerais
Recently, horse breeding has achieved greater prominence in the Brazilian society and now it started to appear as a part of the Brazilian agribusiness. The state of Minas Gerais stands out as the main producer of equidae in Brazil. The aim of this work was to characterize the breeding of equidae in this State in order to support future researches in this sec

3. AVALIAÇÃO DE COMPONENTES DA FIBRA COMO MARCADORES INTERNOS E DE ALCANOS PARA ESTIMAR O FLUXO DE DIGESTA NO DUODENO DE BOVINOS / EVALUATION OF FIBER COMPONENTS AS INTERNAL MARKERS AND ALKANES FOR DUODENAL DIGESTA FLOW ESTIMATION IN CATTLE
The use of ADF as internal Marker of duodenal digesta flow was evaluated, for this the intestinal degradability of fiber was studied. Four Holstein calves (156 33 kg), fitted with duodenal cannula T simple, and one calve fitted on the rumen, fed diet base with black oat and supplement, was used. Seven feeds were weighted on the polyester bags (7x5,5cm; 25

4. Evaluation of models for prediction of the energy value of diets for growing cattle from the chemical composition of feeds
The objective of this study was to estimate and evaluate the contents of apparently digestible fractions of crude protein, ether extract and non-fibrous carbohydrates, the digestible fraction of the neutral detergent fiber and the content of total digestible nutrients (TDN) from the chemical composition of feeds in growing cattle fed different diets. Fourtee

5. Evaluation of the Cornell Net Carbohydrate and Protein System model on the prediction of dry matter intake and milk production of grazing crossbred cows
The Cornel Net Carbohydrate and Protein System model version 5.0 was assessed as for its prediction of dry matter intake and milk production of grazing lactating Holstein × Zebu cows. Eight lactating cows grazing elephant grass (Pennisetum purpureum, Schum., cv. Napier) were used in two experiments of 30 days each. The experimental design was of randomized

6. Desenvolvimento de um sistema de recirculação para estudos sobre digestibilidade em condições de alto desempenho para camarões marinhos: avaliação de ingredientes protéicos alternativos à farinha de peixe em diferentes níveis de inclus / Development of a recirculated system for digestibility studies in high performance conditions for marine shrimp: evaluation of alternative protein sources to fish meal in different dietary inclusion levels for Litopenaeus vannamei juveniles
This thesis focused on the validation of an aquaculture recirculation system (RAS) for shrimp digestibility studies and the determination of the digestibility coefficients of protein sources at different inclusion levels for shrimp feeds. The recirculation system for digestibility studies proved to be adequate for its purpose and shrimp growth rates was equa

7. Utilização de tecidos na avaliação de compostos fibrosos e na degradação ruminal in situ de alimentos para ruminantes / Utilization of textiles in the evaluation of fibrous compounds and in situ ruminal degradation of ruminant feeds
A presente tese foi elaborada com base em quatro artigos. No primeiro artigo objetivou-se avaliar a influência do tamanho das partículas sobre os teores de fibra em detergente neutro (FDN) utilizando-se sacos confeccionados com os tecidos nylon, F57 (Ankom) e tecido não-tecido (TNT 100 g/m). Com o intuito de aferir os teores de FDN obtidos por intermédio

8. OCHRATOXIN A AND CITRININ IN RICE: STUDY OF METHODOLOGY FOR SIMULTANEOUS DETERMINATION OF OCCURRENCE / OCRATOXINA A E CITRININA EM ARROZ: UM ESTUDO DE METODOLOGIA PARA DETERMINAÇÃO SIMULTÂNEA DE OCORRÊNCIA
Ochratoxin A and citrinin are mycotoxins found naturally in foods and feeds. The evaluation of the risk of the consumption of contemned foods for those compositions should be dear starting from reliable data that reflect the true concentration of these toxins in different foods or inputs, especially if ingested frequently. This generates the need of necessar

9. Composição química e energia metabolizável de milho segregado pela mesa gravimétrica e sua utilização na formulação de ração para frangos de corte / Chemical composition and metabolizable energy from of corn segregated by densimetric table and the use in diet formulation for broilers
Quatro experimentos foram conduzidos com o objetivo de determinar os valores nutricionais de milhos de quatro qualidades, obtidos por meio de estratificação em mesa densimétrica. Os milhos foram designados como: MDA - milho de densidade alta; MDI - milho de densidade intermediária; MDB - milho de densidade baixa; e MDO - milho de densidade original, comp

12. A nutrition mathematical model to account for dietary supply and requirements of energy and nutrients for domesticated small ruminants: the development and evaluation of the Small Ruminant Nutrition System
A mechanistic model that predicts nutrient requirements and biological values of feeds for sheep (Cornell Net Carbohydrate and Protein System; CNCPS-S) was expanded to include goats and the name was changed to the Small Ruminant Nutrition System (SRNS). The SRNS uses animal and environmental factors to predict metabolizable energy (ME) and protein, and Ca an
