Sodium Requirement for Muscovy Ducks in Housing
Provedor de dados: 89
Autores: Santos,ANA; Cruz,FGG; Oliveira Filho,PA; Farias,TM; Rufino,JPF; Viana Filho,GB.
ABSTRACT The present study aimed to determine the ideal sodium levels for muscovy ducks in housing. Two hundred and forty muscovy ducks of creole lineage were used, distributed in boxes with water and food ad libitum. The experimental design was completely randomized, where treatments were constituted by six nutritional plans (initial, growth and termination) with different sodium levels, and four replicates of 10 muscovy ducks each. The birds had weekly performance evaluations, and after 90 days, eight birds (four males and four females) in each treatment were slaughtered for evaluation of carcass traits. Data collected were subjected to Tukey test at 5% of significance. Differences were observed (p&lt;0.05) in performance (feed intake and feed...

ABSTRACT The objective of this study was to determine the ideal requirement of sodium to molted laying hens. The experimental period lasted 105 days, divided into five periods of 21 days. Hisex White laying hens 150 with 84 weeks-of-age were used. The experimental design was completely randomized in a factorial scheme (5x3) with treatments constituted by five levels of sodium (0.10, 0.15, 0.20, 0.25, and 0.30%) in the diets, and three postmolt stages (early = 21 days, medium = 63 days, and final = 105 days). Performance and egg quality results were evaluated by Tukey test at 5%. Eggshell resistance and weight gain results were evaluated by polynomial regression at 5%. Except the yolk height, all performance and egg quality variables were affected...

Provedor de dados: 89
Autores: Rufino,JPF; Cruz,FGG; Melo,RD; Feijó,JC; Damasceno,JL; Costa,APG.
ABSTRACT The present study aimed to evaluate ducks on performance, carcass traits and economic availability, fed on different phases of nutritional plans and in different housing densities. Two hundred and forty Muscovy ducks of creole lineage were used, distributed in boxes with water and food ad libitum. The experimental design was completely randomized in a factorial arrangement of 3x2 with three nutritional plans (3, 4 and 5 phases) and two housing densities (2 and 3 birds/m2) with four replicates. The ducks had weekly performance evaluations, and after 90 days, four birds in each treatment were slaughtered for evaluation of carcass traits. Differences (p&lt;0.05) were observed on performance, carcass traits and economic analysis. The nutritional plans...

Autores: Brelaz,KCBTR; Cruz,FGG; Brasil,RJM; Silva,AF; Rufino,JPF; Costa,VR; Viana Filho,GB.
ABSTRACT The present study aimed to evaluate increasing levels of fish waste oil in laying hens diets on performance, egg quality, and sensory features of the eggs. 192 Hisex White laying hens with 29 weeks of age were used, with water and food ad libitum. The experimental design was completely randomized consisting of eight treatments corresponding to the inclusion levels of fish waste oil (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5%) in the diets, with four replicates of six birds each. Data collected were subjected to polynomial regression at 5% of significance. Differences (p&lt;0.05) were observed in feed intake and egg mass. Feed intake increased until 2.50% of fish waste oil in the diets. Differences were not observed (p&gt;0.05) in all variables...

Autores: Batalha,OS; Alfaia,SS; Cruz,FGG; Jesus,RS; Rufino,JPF; Silva,AF.
ABSTRACT This study aimed to evaluate the inclusion of pirarucu by-product acid silage meal in diets for laying hens on performance and egg quality. One hundred sixty eight Hissex White laying hens 73-wk-old were distributed in completely randomized design with seven treatments (0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0%) and four replicates of six birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of pirarucu by-product meal levels were determined by polynomial regression. Differences (p&lt;0.05) were observed in all variables of performance, in egg weight, yolk height and yolk pigmentation, with pirarucu by-product meal inclusion in diets showed better results than control diet. The pirarucu by-product acid silage meal can...

Provedor de dados: 89
Autores: Rufino,JPF; Cruz,FGG; Costa,VR; Silva,AF; Melo,LD; Bezerra,NS.
ABSTRACT In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine. Were used 315 fertile Rhode Island Red eggs were used (breeders with 32-weeks). The experimental design was completely randomized with the treatments constituted by two controls and five solutions containing L-glutamine levels with 45 replicates each. Data collected were subjected to polynomial regression at 5% of significance. Differences (p&gt;0.05) were observed in hatchability and intermediary mortality, with a gradual lower of decrease in hatchability from the IOF of L-glutamine. The yolk sac was higher...

Provedor de dados: 89
Autores: Oliveira Filho,PA; Cruz,FGG; Rufino,JPF; Silva,EM; Viana Filho,GB; Silva,FM.
ABSTRACT The present study aimed to determine the ideal requirement of digestible methionine + cystine to molted laying hens. The experimental period lasted 105 days, divided into five periods of 21 days. 144 Hisex White laying hens with 84 weeks-of-age were used. The experimental design was completely randomized with treatments constituted for six levels of digestible methionine + cystine (0.45, 0.50, 0.55, 0.60, 0.65, and 0.70%) in the diets, with four replicates of six birds each. Data collected were evaluated by polynomial regression at 5%. There was a significant effect (p&lt;0.05) of digestible methionine + cystine on feed intake, energy intake, protein intake, egg production, and egg mass.

Provedor de dados: 89
Autores: Brasil,RJM; Cruz,FGG; Rufino,JPF; Oliveira Filho,PA; Freitas,BKM; Viana Filho,GB.
ABSTRACT The present study aimed at evaluating the effects of a coating based on copaiba oil on the quality of eggs stored for different periods. Eggs were coated with copaiba oil solutions (4, 8, 12, 16, or 20% copaiba oil) or not (control) and stored for 1, 7, 14, 21, 28 or 35 days at room temperature. The following parameters were evaluated: egg weight loss, egg components (albumen, yolk, and eggshell) relative weights, egg specific gravity, Haugh units, eggshell quality, and sensorial attributes. Eggs stored for 35 days presented the highest weight losses. Coating (20% copaíba oil solution) reduced egg weight loss up to 41.02%. Coated eggs presented better internal quality (yolk and albumen heights, specific gravity, and eggshell strength). Sensorial...
