SummaryThe influence of diet quality and stage of lactation on Cheddar cheese moisture and yield were segregated and the effects of other potential variables (cow breed, milk protein genotype, age and level of mastitis) were minimized. An experiment was conducted using milk of cows in mid lactation or late lactation fed on high or low quality diets. Increased moisture in cheese was largely due to the influence of cow diet. Milk from cows given high quality diets produced lower moisture cheese. Cheese yield was influenced by diet and stage of lactation. Cows in late lactation fed on high quality diets always gave milks yielding the most cheese. Fat and protein recovery in cheese was not influenced by diet or stage of lactation. The results suggest that low quality diets may induce changes in the complex interactions of milk proteins and other components that affect cheesemaking.

In response to an increasing demand for public sector accountability, many government agencies have sought to develop their internal evaluation capabilities. Often these efforts have focused on increasing the capacity to supply credible evaluations, yet addressing demand is just as important. This article focuses on a government agency and tracks its five-year journey towards developing such a capability. It documents contextual matters, drivers for change, the actions taken by the agency, and its response to emergent challenges during four phases. Based on feedback from project staff and managers and those involved in the capability development project, it offers seven recommendations. These are: start small and grow evaluation; address both supply and demand; work top-down and bottom-up simultaneously; use a theory of change behaviour; develop a common evaluation framework, including a generic programme theory; build knowledge of what works within the agency's context; and systematically and visibly evaluate each stage.

Fatal cases of herpesvirus infection in a quokka (Setonix brachyurus), eight grey dorcopsis wallabies (Dorcopsis muelleri luctuosa) in two separate outbreaks, as well as presumptive fatal herpesvirus infection in a western grey kangaroo (Macropus fuliginosus) are described. All were captive animals and deaths were preceded by a period of stress. Lesions occurred most often in alimentary tract epithelium, respiratory tract, skin, genital epithelium, conjunctivae, liver and adrenal cortex. Herpesviruses were recovered from the quokka and a grey dorcopsis wallaby from each outbreaks. The implications, particularly concerning certain apparently susceptible species, for those responsible for the health of macropod collections are discussed.
