1. Effect of enzyme addition on energy utilization and performance of broiler chickens fed wheat-based diet with different metabolizable energy levels
ABSTRACT. An experiment was carried out to investigate the effect of multi-enzyme in high and low levels of metabolizable energy (13.81 and 11.51 MJ kg-1 diet) on performance and energy utilization of broilers fed wheat-soybean meal diets from 0 to 21 days of age. Result showed that birds fed diets containing 11.51 MJ kg-1 consumed significantly (p < 0.05) m

2. Availability of betaine present in fine wheat bran in diets for growing pigs
ABSTRACT The objective of this paper was to investigate the availability of betaine present in fine wheat bran (FWB) in diets for growing pigs. We used thirty crossbred intact males, housed individually in metabolic cages and distributed in a randomized block design, with five treatments and six replicates. Blocks consisted of two periods of 15 days. Average

3. Nutritional requirements of energy, protein and macrominerals for maintenance and weight gain of young crossbred Nellore × Holstein bulls on pasture
The objective of this study was to estimate requirements of energy, protein and macrominerals of young Nellore/Holstein crossbreds bulls supplemented on pastures of Brachiaria decumbens Stapf. Thirty-five young bulls, at 8.53±0.18 months of age and with initial body weight of 230.6±6.1 kg were used. Ten animals were slaughtered as reference, in different w

4. NÃveis de isoleucina digestÃvel para suÃnos machos castrados dos 15 aos 30 kg / Levels of digestible isoleucine for barrows from 15 to 30 kg.
Aiming to determine the digestible isoleucine requirement for barrows from 15 to 30 kg, two experiments were conducted, being one of digestibility and another of performance. Ten crossbreed barrows with average initial weight of 15.00 Â 0.27 kg were used to determine the ileal digestibility coefficient of amino acids from basal diet. The animals were housed

5. Efficiency of metabolizable energy utilization for maintenance and gain and evaluation of Small Ruminant Nutrition System model in Santa Ines sheep
This study was carried out to estimate efficiencies of the utilization of metabolizable energy for maintenance (k m) and weight gain (k g) and to evaluate the Small Ruminant Nutrition System (SRNS) model in predicting dry matter intake and average daily gain of growing Santa Ines sheep. Twenty-four non-castrated Santa Ines sheep, at 50 days of age and with a

6. A model for evaluating beef cattle rations considering effects of ruminal fiber mass
A mathematical model based on Cornell Net Carbohydrate and Protein System (CNCPS) was developed and adapted in order to evaluate beef cattle rations at tropical climate conditions. The presented system differs from CNCPS in the modeling of insoluble particles' digestion and passage kinetics, which enabled the estimation of fiber mass in rumen and its effects

7. Estudo do valor nutritivo do farelo de guandu (Cajanus cajan (L.) Millps) var. fava larga na alimentacao de frangos de corte. 1. Avaliacao do tratamento termico.
O experimento teve como objetivo avaliar o efeito do tratamento termico sobre os fatores antinutricionais presentes no guandu. Foram utilizados 288 pintos de corte em duas baterias metalicas, distribuidos num delineamento experimental em quantro blocos, num esquema fatorial de 3 x3, em tres temperaturas: 100, 110 e 120 C e tres tempos de autoclavagem: 10, 20

8. Combined use of ionophore and virginiamycin in confined Nellore steers fed high concentrate diets / Uso combinado de ionóforo e virginiamicina em novilhos Nelore confinados com dietas de alto concentrado
Zebu cattle fed high concentrate diets may present metabolic disorders, such as ruminal acidosis and liver abscesses. Also these animals display inconsistent performances in high starch diets. The use of feed additives such as ionophores and virginiamycin has been thoroughly investigated and the results are very consistent, with improvements in performance,

9. Using the enzyme phytase in feed for laying Japanese quails / Uso da enzima fitase em ração para codornas japonesas em postura
There were two experiments to evaluate the effect of adding the enzyme phytase in the diet on the performance and eggs quality (experiment I) and the use of the feed ingredients (Experiment II) for laying Japanese quails. In the first experiment were used 320 quail females of Japanese sub- species, with 167 days old, initial weight of 182.3 + 3.8 g and rate

10. Utilization of probiótico in diets of broilers chickens: performance, nutrients digestibility and metabolizable energy / Uso de probiótico em rações de frangos de corte: desempenho, digestibilidade e energia metabolizável
Two trials were conduced at the UFV Animal Science - department of Aviculture, to determine performance, nutrients digestibility and energetic values in poultry feed. Broilers performance, nutrients ileal digestibility and apparent metabolizable energy (AME) and apparent corrected (AMEn) of diets formulated with two levels of energy, supplemented or not with

11. Net energy evaluation of feeds and determination of net energy requirements for pigs
Feeds for pigs can be attributed different energy values according to, first, the step considered in energy utilization (DE: digestible energy, ME: metabolizable energy and NE: net energy) and, second, the method used for estimation at each step. Reference methods for evaluating DE content are based on in vivo digestibility measurements; indirect estimates o

12. Development and evaluation of a mathematical model to predict the nutritional value of rations for cattle liable to rumen fiber mass restrictions / Desenvolvimento e avaliação de um modelo matemático para predição do valor nutricional de rações para bovinos sujeito às restrições da massa de fibra no rúmen
A mathematical model based on Cornell Net Carbohydrate and Protein System (CNCPS) was developed and adapted to evaluate beef cattle rations at tropical climate conditions. The presented system differs from CNCPS in the modelling of insoluble particles digestion and passage kinetics, which allowed to estimate ruminal fiber mass and its effects on animal perfo
