13. Effect of Egg Position in the Incubator on Broiler Hatching Results
ABSTRACT This study investigated whether the effect of egg location during incubation on hatching results in broiler eggs. For this purpose, a total of 756 broiler eggs were incubated for 21 days. The eggs were divided near the door and near the fan, and distributed on top (216 eggs), 324 in the middle (324 eggs), and in the bottom (216 eggs) according to a

14. Physical-Chemical and Sensorial Quality of Eggs Coated With Copaiba Oil Biofilm and Stored At Room Temperature for Different Periods
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 lo

15. Fish Waste Oil in Laying Hens* Diets
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 i

16. Transmission control of schistosomiasis mansoni in a low endemicity area through a single intervention with rigorous prospection of infected cases treated with praziquantel: evaluation after 7 years of intervention
ABSTRACT A prospective cohort study with rigorous searching for schistosomiasis cases was conducted among residents of Pedra Preta, Montes Claros, Minas Gerais State, Brazil, seven years after an intervention. Kato-Katz (KK), Saline Gradient, Miracidia Hatch and Polymerase Chain Reaction (PCR) were used as the diagnostic methods in 2008. In the period of 201

17. Effect of In Ovo Feeding of L-Glutamine to Chick Embryos
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 compl

18. Optimal Available Phosphorus Levels in Diets Containing Different Dicalcium Phosphate Particle Sizes for Japanese Quails
ABSTRACT This experiment was conducted to investigate the effects available phosphorus levels and dicalcium phosphate particle size on the live performance, and egg parameters and bone parameters of Japanese quails in lay. The experimental diets were based on corn and soybean meal and formulated to contain 2900 kcal metabolizable energy (ME)kg-1, 200 g kg-1

19. Comparison of the Dietary Supplementation of Lactobacillus plantarum, and Fermented and Non-Fermented Artemisia Annua on the Performance, Egg Quality, Serum Cholesterol, and Eggyolk-Oxidative Stability During Storage in Laying Hens
ABSTRACT Artemisia annua L. is a widely distributed medicinal plant and well-known for treating malaria due to the artemisinin content. We previously found enhanced antioxidant and antibacterial activities of Lactobacillus plantarum-fermented A. annua dried leaves in vitro. The present study compared the effects of the dietary supplementation of L. plantarum

20. Morphological Investigations of the Effect of Thermal Manipulation During Embryogenesis on Body Performance and Structure of Pectoral and Thigh Muscle of Ross Broiler Chicken
ABSTRACT The aim of this study was to determine the optimum timing of thermal manipulation during early, mid, late and long lasting embryogenesis that may result in improvement of body performance and myofiber development (fiber diameter and thickness of perimysium) of pectoral and thigh muscles by a comparative morphometrical investigation on post-hatch day

22. EFEITO DO PARASITISMO POR Haemonchus contortus SOBRE O METABOLISMO OXIDATIVO DE LEUCÓCITOS DE OVINOS
Resumo A resposta imune tardia direcionada para eliminação da hemoncose pode ser modulada pelo perfil Th2, sendo os eosinófilos as principais células efetoras responsáveis pela eficiente eliminação do parasita; ou modulada pelo perfil Th1, sendo os neutrófilos as principais células efetoras, que promovem eliminação parasitária mais deficiente, po
