	abstract = {During the time sheep are aborting from Salmonella Brandenburg infection, black-backed gulls have the ability to contaminate stock water and pasture with S. Brandenburg. This enables these birds to play a significant role in the local spread of diseases caused by this organism. They also have the ability to spread other diseases, such as sheep abortions due to Campylobacter. },

	abstract = {A method for the evaluation of the rate of fatty acid accumulation and recycling in adipose tissue in vitro is described.  The influence of insulin on fatty acid accumulation in adipose tissue is shown to be greater than its influence on fatty acid manufacture. This was achieved by the ability of the hormone to reduce the rate at which fatty acid was mobilised from the adipose tissue. It is proposed that studies of the total fatty acid balance in this tissue will provide a better understanding of the effects of hormones on overfatness in meat animals than a study which simply addresses the rate of fatty acid manufacture.},

	abstract = {Results from vitamin B12 response trials are used to illustrate a methodology which it is claimed will provide a more useful interpretation of animal tissue analyses for the diagnosis of trace element deficiencies. Traditional reference ranges which divide tissue levels into the categories of responsive, marginal, and adequate are replaced by reference curves which, for a given tissue level, provide the expected response and the probability of an {\textquoteright}economic response. The approach should provide farmers and veterinarians with better information to decide on remedial action. The prospects look promising for the production of reference curves for cobalt and selenium, and hopeful for copper. It is suggested that the methodology could be applied in other biological systems involving deficiencies, in particular, to the diagnosis of phosphorus and other deficiencies in plants.},

	abstract = {Responses to sodium supplements have been recorded in trials with weaner Angus calves and mature ewes grazing pastures containing Na concentrations exceeding the minimum dietary levels calculated from recent Agricultural Research Council (1980) recommendations. Increased live-weight gains were noted following supplementation of calves grazing pastures with a Na content of 1 g/kg DM, and in ewes on pasture with 0.7 g/kg DM. These results suggest that either the estimates of daily Na requirements are too low or that for Na availability is too high.},
