	abstract = {A factorial design was used to determine the effect of offering cows (n=8) in early, mid, and late lactation 50 MJME/cow/day of rolled maize grain (T2) or a nutritionally balanced supplement (T3) in spring, summer, autumn and winter at a restricted pasture allowance. The average milksolids production of the early, mid and late lactation groups was 1.16, 1.10, and 0.96 kg MS/cow/day ({\textpm} 0.013), respectively. When compared to a non-supplemented control (T1), offering T2 and T3 supplements increased MS production from 0.91 to 1.14 and 1.13kg MS/cow/day (P<0.01), respectively. The milksolids responses to T2 was 150g MS/cow/day greater in summer and winter than in spring and autumn (P<0.05). Stage of lactation, or form of supplement, had no effect on milksolids response (P>0.05). These results suggest that the milksolids response to supplementary feeding was determined by the extent supplementary feeding increased total ME intake. },

	abstract = {In New Zealand, seasonal calving has created marked variations in the volume and composition of milk supplied to processors across the season. As a consequence, there are also seasonal variations in the manufacturing properties of the milk (Kefford et al.1995). In particular, milk from later in the season can have manufacturing properties which are different from those of early and mid-season milk. Milk from this time typically has elevated concentrations of blood proteins, low casein:whey ratios and an altered min-eral balance (Lucey, 1996). The 2 major factors attributed to causing this phenomenon are the stage of lactation (SOL) of the cows, and seasonal influences which affect both pasture and cows. In a seasonally-calving dairy sys-tem, the precise contributions of these factors to the re-ported changes in milk composition are difficult to define because of the confounding influences of other factors. The aim of the investigation presented here was to separate the respective effects of season and SOL on milk composition.},

	abstract = {The adoption of seasonal calving in New Zealand has lead to marked irregularities in the supply of milk to processors in terms of both quantity and quality. The need to accommodate peak milk flow means that manufacturing plants are under utilised for most of the year. Further, there are difficulties manufacturing high quality products early and late in the season. This study presents data from an all-year-round calving system which may help to overcome the above mentioned problems.},
