Selection strategies for body weight and reduced ascites susceptibility in broilers.
Ascites syndrome is a metabolic disorder in broilers. Mortality due to ascites results in significant economic losses and has a negative impact on animal welfare. It has been shown that genetic factors play a considerable role in susceptibility of birds to ascites, which offers perspectives for selection against this syndrome. The aim of the present study was to evaluate the consequences of alt...
متن کاملSelection strategies for limiting the increase in ascites while increasing growth in broilers.
The objective of the current study was to compare the changes in a fitness trait when selection is performed for 5, 10, and 20 generations on a production trait that influenced its expression. Responses to single-trait selection for growth based on phenotype or animal model predictions were compared by computer simulation. Two-trait index selection was performed when a trait, related to the fit...
متن کاملHeritability of sudden death syndrome and its associated correlations to ascites and body weight in broilers.
(1) Genetic parameters for the sudden death syndrome (SDS) were estimated in meat-type chickens. Data were collected over 11 generations of selection for body weight within two distinct breeds (Cornish and White Rock). (2) The animal model was used exclusively with linear methods (LM) to estimate genetic parameters. Heritability (h2) of SDS on the liability scale was 0.30 +/- 0.002 and 0.25 +/-...
متن کاملGenetic Perspective of Ascites Syndrome in Meat-Type Chickens
Pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. Inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. Incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. The objective of the current study was to review the genetic b...
متن کاملAscites Incidence in Broilers
Gejala umum terjadinya sindrom ascites pada ayam broiler adalah berupa akumulasi cairan yang berlebihan di rongga peritoneal yang menyebabkan peningkatan tekanan pembuluh arteri pulmoner. Kondisi ini dapat menyebabkan kematian akibat kurangnya suplai oksigen untuk kebutuhan metabolis tubuh. Angka kematian akibat Ascites pada ayam broiler adalah sebesar 5%. Sindrom ascites dapat dicegah dengan m...
