Body Conformation and Internal Organs Characteristics of Different Commercial Broiler Lines Rev. Bras. Ciênc. Avic.
Kokoszyński,D; Bernacki,Z; Saleh,M; Stęczny,K; Binkowska,M.
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 308 chickens had significantly (p≤0.05) shorter trunk, but greater chest circumference and compactness index, as well as shorter esophagus and longer large intestine compared with Hubbard F15. The longest large and total intestine was found in Ross 308 broilers. Chicken genotype had no significant effect on the percentage of the main internal organs, i.e. liver, heart, proventriculus, gizzard, and...

Body Morphometry and Development of the Digestive System of Grey Partridge (Perdix Perdix) Depending on Age and Gender Rev. Bras. Ciênc. Avic.
Kokoszyński,D; Biegniewska,M; Wilkanowska,A; Saleh,M; Bernacki,Z; Stęczny,K; Kmiecik,M.
ABSTRACT The experiment used 100 grey partridges (Perdix perdix L.), which were reared first in confinement and later in aviaries. Partridges were lighter and had greater body dimensions at 36 weeks compared to 12 weeks except for trunk length. Older birds showed greater values (p>0.05) of compactness and lower values of massiveness and long-leggedness. Significant differences were found for keel length in females. At 36 weeks, male and female partridges had significantly greater total intestinal length, males had significantly longer small intestine and rectum, and females were characterized by significantly longer caeca and greater (p<0.05) intestine to body length ratio. Older birds had significantly greater gizzard weight and percentage and heart...
