Item A genome-wide association study reveals novel genomic regions and positional candidate genes for fat deposition in broiler chickens(BioMed Central Ltd, 2018-05-21) Moreira GCM; Boschiero C; Cesar ASM; Reecy JM; Godoy TF; Trevisoli PA; Cantão ME; Ledur MC; Ibelli AMG; Peixoto JDO; Moura ASAMT; Garrick D; Coutinho LLBACKGROUND: Excess fat content in chickens has a negative impact on poultry production. The discovery of QTL associated with fat deposition in the carcass allows the identification of positional candidate genes (PCGs) that might regulate fat deposition and be useful for selection against excess fat content in chicken's carcass. This study aimed to estimate genomic heritability coefficients and to identify QTLs and PCGs for abdominal fat (ABF) and skin (SKIN) traits in a broiler chicken population, originated from the White Plymouth Rock and White Cornish breeds. RESULTS: ABF and SKIN are moderately heritable traits in our broiler population with estimates ranging from 0.23 to 0.33. Using a high density SNP panel (355,027 informative SNPs), we detected nine unique QTLs that were associated with these fat traits. Among these, four QTL were novel, while five have been previously reported in the literature. Thirteen PCGs were identified that might regulate fat deposition in these QTL regions: JDP2, PLCG1, HNF4A, FITM2, ADIPOR1, PTPN11, MVK, APOA1, APOA4, APOA5, ENSGALG00000000477, ENSGALG00000000483, and ENSGALG00000005043. We used sequence information from founder animals to detect 4843 SNPs in the 13 PCGs. Among those, two were classified as potentially deleterious and two as high impact SNPs. CONCLUSIONS: This study generated novel results that can contribute to a better understanding of fat deposition in chickens. The use of high density array of SNPs increases genome coverage and improves QTL resolution than would have been achieved with low density. The identified PCGs were involved in many biological processes that regulate lipid storage. The SNPs identified in the PCGs, especially those predicted as potentially deleterious and high impact, may affect fat deposition. Validation should be undertaken before using these SNPs for selection against carcass fat accumulation and to improve feed efficiency in broiler chicken production.Item Bounded bodies : the everyday clothing practices of larger women : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Sociology, Massey University, Albany, New Zealand(Massey University, 2011) Cain, Trudie MelissaThe field of dress studies currently emphasises dress as an embodied practice, but surprisingly scant attention has been awarded to the fat fleshy clothed body. This thesis addresses this lacuna, and is concerned with the everyday clothing practices of larger women. Theoretically, I draw on and integrate literature from material culture studies, as well as from the politics of fatness, the latter serving as the socio-cultural foundation for the research. In doing so, my research contributes to and extends the current body of literature that considers dress as material culture. This thesis offers further extension of the field through the methodological focus of the research. Employing multiple inter-related methods allows the complex social processes of larger women?s clothing practices to be revealed. Often these processes are embedded within the seemingly habitual, mundane, everyday things that people do while operating within a particular social milieu. With this in mind, I employ an ethnographically-inspired, multiple-method research methodology to explore the everyday clothing practices of ten self-identified larger women in Auckland, New Zealand. The five research methods involve asking the participants to: keep a clothing journal; rummage through their wardrobe with me; go shopping for clothes with me; take photographs of their „clothed worlds?; and take part in a group discussion with other participants. Employing an integrative analytic process, I reveal the numerous ways that larger women enact their agency at the same time as being bound within structures of socio-cultural corporeal and clothing norms. My research shows that the boundaries between fleshy fat bodies, clothing and culturally-bound geographical spaces are experienced by my participants as tension-filled and ambiguous. Ultimately, they are perpetually provisional; the boundaries fixed yet potentially permeable. Using space as an organisational and analytic framework, my research explores the boundaries of four distinct spaces: spaces of consumption; public spaces beyond consumption; private spaces; and the spaces between fat bodies and clothes. I argue that, despite structural barriers that create „fat? bodies as „matter out of place? and, as such, beyond the bounds of possibility, larger women enact agency in creative and resourceful ways. In doing so, they challenge the boundaries of dominant Western constructions of fatness and ultimately, transform places of exclusion into spaces of inclusion.
