	abstract = {A total of 60 Friesian x Jersey heifer calves were allocated to a 2{\texttimes}2 factorial design to investigate early life nutrition on growth and production. The first factor was the maternal treatments where dams were offered a low crude protein (7.8\% LCP) or moderate crude protein (13.6\% MCP) diet for the last 50 days of gestation. The second factor was the calf milk replacer (CMR) allowance to heifer offspring, which was either restricted (RES) or high allowance (HA) allowance (15 or 25\% of initial live weight, respectively). All calves were given colostrum for 4 days then, warmed CMR (150 g/L) in two equal feeds between days 5 and 39, after which all calves received the same 15\% allowance. Milk intake, liveweight gain and fecal score were recorded for 5 weeks. Calves were weaned off milk at 8 weeks of age. The HA treatment improved weaning weight (88 vs 79{\textpm}1.4 kg; P<0.001) and overall ADG pre-weaning (0.9 vs 0.8{\textpm}0.02 kg/day; P<0.001) compared to RES. There was no effect of maternal diet on pre-weaning growth or fecal score. There was limited statistical evidence of a long-term effect of early life nutrition on milk yield, though maternal nutrition appeared to be more important than pre-weaning nutrition on future milk production.},

	abstract = {Varying the regrowth interval, pre-graze herbage mass and mowing pasture prior to grazing are strategies used to try to improve pasture quality and nutrient availability to grazing livestock.  This study compared the nutritive value of pastures which had been mown before grazing, or grazed as standing pastures following a long (Long, 28 days) or moderate (Mod, 21 days) regrowth interval.    Nutritive value and dry matter percent were determined at 0, 1, 2, 3, 4, 6, 12 and 24 hours in replicated paddocks during a 24-hour grazing period following allocation to dairy cows at 0700 h.  Due to previous grazing management, which maintained a high proportion of leafy material in the grazed stratum, the nutritive value of the available herbage before grazing was similar for all treatments. Mowing before grazing resulted in a relatively constant nutrient supply over a 24 h grazing period; however, this did not alter cow performance (e.g., milksolids production or BCS) compared with grazing standing pasture.  By contrast preferential selection of higher quality pasture by cows grazing standing pasture resulted in lower concentration of herbage crude protein (P<0.05) and greater concentration of fibre (P<0.05) at the end of the grazing period.  When pastures were mown, herbage wilted, increasing DM from 17.5 to 39.4\% DM within 24 hours (P<0.05).  Despite large differences in pasture management, extending the regrowth interval and using repeated pre-graze mowing did little to alter herbage nutritive content.},

	abstract = {To investigate whether feeding strategies to reduce urinary N excretion would have negative effects on calf development, two
feeding systems were compared. A total of 190 pregnant, Friesian {\texttimes} Jersey dairy cows were randomly allocated to one of two
groups and offered either a low crude protein diet of maize silage and fodder beet (LCP) or a moderate CP diet of lucerne silage
and fodder beet (MCP) for eight weeks prior to calving. Apparent metabolisable energy (ME) intake of dams was similar (110
MJME/cow/day) but CP concentration was greater for MCP than LCP (13.4 vs 7.5\% of the DM). There was no effect of maternal
diet on calf birth weight (33.0{\textpm}0.5 kgLW) or morphometric measurements; heart girth (72.8{\textpm}0.5) spine length (54.4{\textpm}0.4) or hip
height (73.1{\textpm}0.4 cm). These results suggest that dietary protein restriction in late gestation does not have any immediate negative
effects on in utero calf development.},
