An HSUS Report: Welfare Issues with Selective Breeding for Rapid Growth in Broiler Chickens and Turkeys
Chickens and turkeys raised commercially for meat production are selectively bred to reach market weight rapidly. As consequence of unnaturally rapid growth and heavy body weight, these birds often experience skeletal and metabolic disorders that severely compromise their welfare, including lesions in the hip joint and painful leg disorders, such as angular bone deformity, tibial dyschondroplas...
متن کاملVisuospatial selective attention in chickens.
Voluntary control of attention promotes intelligent, adaptive behaviors by enabling the selective processing of information that is most relevant for making decisions. Despite extensive research on attention in primates, the capacity for selective attention in nonprimate species has never been quantified. Here we demonstrate selective attention in chickens by applying protocols that have been u...
متن کاملBREEDING AND GENETICS Heterosis and DNA Fingerprinting in Chickens
Enhancement of performance in traits of economic importance by use of heterosis (hybrid vigor) is routine in poultry breeding. There is, however, no reliable method to predict the level of heterosis that will occur from the mating of individuals from two populations. DNA fingerprints (DFP) were used as a measure of genetic distance between mating pairs of chickens where each individual of a pai...
متن کاملLinkage disequilibrium in related breeding lines of chickens.
High-density genotyping of single-nucleotide polymorphisms (SNPs) enables detection of quantitative trait loci (QTL) by linkage disequilibrium (LD) mapping using LD between markers and QTL and the subsequent use of this information for marker-assisted selection (MAS). The success of LD mapping and MAS depends on the extent of LD in the populations of interest and the use of associations across ...
متن کاملSelective breeding for the control of nematodiasis in sheep.
Genetic manipulation of sheep by selective breeding offers a means to reduce the current reliance on chemotherapy for the control of gastro-intestinal nematodes. Simulated epidemiological studies support this view as, compared to lambs of 'normal' susceptibility, those 'selected' for resistance to Trichostrongylus colubriformis have lower worm burdens and reduced production losses. Considerable...
