	abstract = {Changes in various blood parameters can be used to assess the relative  stressfulness of farm practices. In order to overcome confounding effects of  stress inherent in standard methods of blood collection, a portable remote  blood sampling device ("Dracpac") has been developed and tested. Twelve  heparinised blood samples can be taken from the jugular vein and stored in  insulated packs on the animal. The stability of blood parameters taken from  and stored on red deer was determined. Analyses of subsamples taken from a  bulk initial sample over 12 hours showed that levels of cortisol, haematocrit  and glucose did not significantly differ from initial values. In a second  experiment stags were sampled remotely during restraint in a mechanical crush  and subsequent recovery at pasture on 2 successive days. On both days  cortisol, haematocrit, glucose and lactate levels were elevated during restraint  and thereafter decreased significantly to reach levels substantially lower than  previously reported for this species using standard methods of blood sampling.   The development of this device permits reliable remote blood sampling of free  ranging animals without the stress associated with manual blood sampling.  },

	abstract = {The mean interval from the end of synchrony treatment to the onset of  oestrus can be highly variable and as a consequence {\textquoteright}single-time{\textquoteright} inseminations  may occur at other than optimal times. This study was undertaken to identify  some of the factors influencing the interval to oestrus following synchrony  treatment, and to develop a spreadsheet model to assist with determining the  timing of AI in ewes under a range of oestrous onset patterns. Synchrony  device, PMSG, time of year, and live weight tended to have important effects  on the interval to oestrus. Ewe genotype and year effects were generally small.   Three new concepts have arisen from the modelling exercise. Firstly, the actual  timing of AI to achieve near maximum fertility depends on the mean interval to  oestrus in a given flock, but not the precision of synchrony or the incidence of  ewes that are synchronised. Secondly, the {\textquoteright}tolerance{\textquoteright} about this optimum time  of insemination depends on how much is known about the mean interval to  onset (more information means more tolerance). Thirdly, the {\textquoteright}tolerance{\textquoteright} about  this optimum time of insemination depends on the maximum reduction in flock  pregnancy rate that is acceptable to the flock owner (higher reduction means  more tolerance). If the onset pattern in a particular flock is unknown, the  {\textquoteright}universal{\textquoteright} timing for a single fixed-time AI during the breeding season is 42-  46 h after CIDR},
