	abstract = { The objective of this study was to determine the effect of feeding maize silage at different times before the herbage meal on dry
matter (DM) intake, milksolids (MS) production and nitrogen (N) excretion of late lactation dairy cows. In an indoor study, nine
Friesian {\texttimes} Jersey dairy cows were assigned to three treatments: (1) herbage only (control); (2) supplemented with 3 kg DM of
maize silage after morning milking approximately nine hours before the herbage meal (9BH); and (3) supplemented with 3 kg DM
of maize silage after afternoon milking approximately one hour before the herbage meal (1BH). Cows were offered ad libitum cut
herbage (perennial ryegrass-white clover) for five hours from 1530 to 2030 h. Herbage DM intake was greater (P=0.03) for control
than 1BH cows, but did not differ between control and 9BH or between 1BH and 9BH cows (13.71, 11.96 and 12.74 kg DM/cow/
day for control, 1BH and 9BH, respectively). The substitution of herbage by maize silage was greater (P=0.05) for 1BH than 9BH
cows (0.56 vs 0.31 kg DM herbage per kg DM maize silage, respectively). Milksolids production did not differ between treatments
(overall mean 1.33 kg MS/cow/day). Nitrogen concentration in faeces and estimated urinary-N excretion (g/day) were lower in
supplemented than control cows. Under herbage restriction, it is important to consider time of maize silage supplementation
relative to the herbage meal for managing substitution rate and urinary-N excretion.},

	abstract = {<p>Subclinical endometritis (SCE) is a form of uterine pathology characterised by an increased proportion of polymorphonuclear cells (PMN) in the uterus post-calving. Previous studies demonstrated a negative association between SCE and lower milk production, with indications that systemic inflammation underlies this link. Accordingly, the hypothesis tested was that treatment with a non-steroidal antiinflammatory drug (NSAID) would increase milk yield in cows with >= 14\% PMN at Day 14. In this study, >= 14\% PMN in the cytological sample collected at Day 14 postpartum was defined as SCE. To test this hypothesis, 213 dairy cows were paired by calving date and Day 14 PMN\%, then randomly assigned to three doses of a NSAID (Carprofen 1.4 mg/kg, n = 103) between 21 and 31 days postpartum or left as untreated controls (n = 108). The effect of the NSAID treatment on milk production was analysed using mixed models. While the results supported previous evidence of a negative association between SCE and milk production, NSAID had no effect on either PMN \% at Day 42 or milk production (P \&gt; 0.1) in this study. The lack of a NSAID effect was possibly because SCE spontaneously resolved in more than 90\% of the cases</p>
