1. Descriptive Anatomy of Hepatic and Portal Veins with Special Reference to Biliary Duct System in Broiler Chickens (Gallus gallus domesticus): A Recent Illustration
ABSTRACT Chickens have a great participation in meat and egg production. The anatomical scientific data of poultry is important to support the recent researches either for illustrations in academic studies or clinically in diagnosis and treatment of some poultry nutritional diseases. The current investigation was performed on twenty broiler chickens of both

6. Organic minerals with different chemical characteristics in diets for Hy-Line White laying hens: performance, biometry of digestive organs, and bone quality
ABSTRACT Two trials were carried out to evaluate the effect of groups of organic minerals with different chemical characteristics on the performance, egg quality, biometry of digestive organs, and bone quality of laying hens in the first and second laying cycles. In the first cycle, 180 layers at 72 weeks were used in a completely randomized design (CRD) wit

7. Effect of Feeding Transcarpathian Zeolite on Gastrointestinal Morphology and Function in Broiler Chickens
ABSTRACT Many kinds of feed additives can be used in chicken diets to stimulate intestinal morphological maturation and, consequently, intestinal function. The purpose of this study was to evaluate the effect of zeolite on broiler performance, gut morphology and gut digestive enzyme activity. The one-day old broiler chickens Ross 308 were assigned randomly i

8. Breed and Sex Differences in the Gross Anatomy, Digesta pH and Histomorphology of the Gastrointestinal Tract of Gallus Gallus Domesticus
ABSTRACT A study was conducted to investigate the influence of breed and sex in the gross anatomy, digesta and histology of Ross 308 broiler and Venda chickens. Chickens were slaughtered at 90 days of age and the pH of the digestive organs was measured immediately after slaughter. The digestive organ weights and lengths of Ross 308 broiler and Venda chickens

9. Body Conformation and Internal Organs Characteristics of Different Commercial Broiler Lines
ABSTRACT The aim of the study was to determine body weight and dimensions, body conformation, length of the esophagus, length of intestine and its segments, as well as weight of internal organs and their proportions relative the body weight of broiler chickens from three commercial lines - Ross 308, Hubbard Flex and Hubbard F15. At the age of 42 days, Ross 3

10. Effects of Laser Beak Trimming on the Development of Brown Layer Pullets
ABSTRACT Laser beak trimming is a promising alternative to conventional hot-blade beak trimming as it is less painful and provides better beak uniformity and better animal welfare. In this study, laser vs. hot-blade beak trimming were compared in 400 Hy-line Brown pullets between 2-16 weeks of age. At 7 days of age, birds were distributed according to a comp

11. Feeding Programs for Broiler Breeders in the Start Phase
ABSTRACT The fast-growing Brazilian aviculture requires studies to improve zootechnical performance indexes for broiler breeders. The purpose of this study was to assess different feeding programs for broiler breeders on performance and development of digestive organs. A total of 48,000, 1d-old, Cobb 500 broiler breeders were divided into two sheds with 24,0

12. Effects of Arginine Supplementation on Organ Development, Egg Quality, Serum Biochemical parameters, and Immune Status of Laying Hens
Abstract This experiment was conducted to study the effects of arginine supplementation on organ development, egg quality, blood parameters, and immune status of laying hens. A total of 360 25-week-old brown Leghorn laying hens were randomly divided into three groups with six replicates of 20 birds each and fed diets supplemented with 0, 8.5, or 17 mg of L-a
