Genetic and phenotypic relationships between blood gas parameters and ascites-related traits in broilers.
Ascites, also called pulmonary hypertension syndrome, is a metabolic disorder in chickens that have an insufficient pulmonary vascular capacity. The tendency of broilers to develop ascites is heritable, and successful selection against this susceptibility would benefit from good and easy-to-measure indicator traits. Blood gas parameters have been suggested as indicator traits for ascites suscep...
متن کاملDirect and maternal genetic effects for ascites-related traits in broilers.
The objective of the present study was to estimate heritabilities for ascites-related traits in broilers and to assess the importance of maternal genetic effects for these traits. Several traits related to ascites were measured on more than 4,000 broilers kept under cold conditions. Heritabilities were estimated using an animal model with a direct genetic effect and a model with direct and mate...
متن کاملRelationship between venous blood gas parameters, thyroid hormone levels and ascites syndrome in broiler chickens exposed to cold temperature
The objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. One hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. Toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...
متن کاملGenetic Relationships among Three Yarrow Species Based on Phenotypic Traits and Peroxidase Profiling
Fifteen yarrow populations from different species Achillea millefolium L., A. biebersteinii L. and A. nobilis, from different geographical areas of Iran were studied using 24 morphological traits and peroxidase profiles. Comparison of mean values of different phenotypic traits show A. millefolium and A. biebersteinii L. had higher plant height and crown diameter; however, A. nobilis had higher ...
متن کاملGenetic and Phenotypic Parameters for Milk Production Traits in the First and Second Lactation in Romanian Simmental Dairy Cows
The aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of Romanian Simmental dairy cattle. For the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
