Genetic and nutritional control of fat deposition in ruminants - LS1003

Objective
(1) Determine effect of diet on cattle performance parameters: daily feed intake, growth rates and body composition assessed in vivo. (2) Determine effect of diet and stage of development on carcass composition in cattle. (3) Determine effect of genotype on adipose tissue growth in different depots at different stages of maturity in sheep. (4) Monitor temporal changes in adipose tissue development due to hypertrophy and /or hyperplasia of adipocytes. (5) Investigate if and when intramuscular pre-adipocytes differentiate and investigate factors which may influence their development and responsiveness to endocrine signals. (6) Consider relationship between fat and lean deposition when 'growth' is controlled by diet or by genotype. To investigate possible reasons for the late development of intramuscular fat and explore the possibility that there are metabolic signals from muscle fibre which influence the proliferation and differentiation of adipocytes. (7) Investigate the interaction between genotype and nutrition in both sheep and cattle. (8) Suggest methods of husbandry and animal breeding which will lead to better quality ruminant meat.
