Selection for improved leg health in purebred broiler lines
نویسنده
چکیده
Leg health has been an important component of broiler welfare and of the economy of broiler production for many decades and includes a wide range of leg disorders leading to locomotion problems (e.g. Thorp, 1994; SCAHAW, 2000; Bradshaw et al., 2002). This article will focus on five leg health traits recorded within the Aviagen Ltd (Newbridge, UK) breeding programme, namely (1) long bones deformities (LD), including valgus/varus and bowed legs, (2) crooked toes (CT), (3) tibial dyschondroplasia (TD), (4) hock burn (HB) and (5) foot pad dermatitis (FPD).

Genetic basis of leg health and its relationship with body weight in purebred turkey lines
The aims of this study were to estimate the genetic parameters for leg and foot health and mobility in purebred turkey lines and their genetic correlations with BW. Traits were gait score (GS) as an overall measure of leg health, footpad dermatitis (FPD), and 2 skeletal leg health traits, namely, valgus and varus deformities (VVD) and tibial dyschondroplasia (TD). Data from 4 different lines, c...

This study sought to assess mitochondrial DNA (mtDNA) diversity and phylogeographic structure of chickens from five agro-ecological zones of Zimbabwe. Furthermore, chickens from Zimbabwe were compared with populations from other geographical regions (Malawi, Sudan and Germany) and other management systems (broiler and layer purebred lines). Finally, haplotypes of these animals were aligned to c...
متن کاملGenetic parameters of foot-pad dermatitis and body weight in purebred broiler lines in 2 contrasting environments.
The aims of this study were to investigate the genetic background of foot-pad dermatitis (FPD) in 4 different broiler lines reared in 2 contrasting environments (pedigree or sib-test) and to evaluate the performance of simultaneous genetic selection for improved FPD and BW. Data were available for 4 generations from 4 broiler lines, bred with varying intensities of selection for growth. The ave...
متن کاملThe genetic basis of pectoralis major myopathies in modern broiler chicken lines
This is the first report providing estimates of the genetic basis of breast muscle myopathies (BMM) and their relationship with growth and yield in broiler chickens. In addition, this paper addresses the hypothesis that genetic selection for increase breast yield has contributed to the onset of BMM. Data were analyzed from ongoing recording of BMM within the Aviagen breeding program. This study...
متن کاملEstimation of genotype imputation accuracy using reference populations with varying degrees of relationship and marker density panel
Genotype imputation from low-density to high-density (SNP) chips is an important step before applying genomic selection, because denser chips can provide more reliable genomic predictions. In the current research, the accuracy of genotype imputation from low and moderate-density panels (5K and 50K) to high-density panels in the purebred and crossbred populations was assessed. The simulated popu...
