is a moderate negative at -2.9 and Calving Ease at -1.8 will eliminate his use on heifers without expecting real calving issues. Twist daughters should be good herd cows based on their good temperament (1.45), great locomotion and move- ment (2.18) and ability to work hard producing high vol- umes without sacrificing condition (Twist has a positive 0.86 condition score). Despite the limited daughter information, his linear proof indicates a balance with limited areas for concern and he is likely to appeal to an array of breeding objectives. There are just over 90 Twist daughters registered in the UK, the eldest born in October 2007 and of these only 32 have been scored so far, with the highest ranked being the VG87-2yr


Wyndhurst Twist Rachel who is from a GP82 Moet Rockwell cow. She is one of three VG daughters with a further 19 clas- sified GP. Twist daughters should be tall (1.71 stature) with frame and robustness (angularity is only 0.35), while showing a slope to the rump and width. His Feet & Legs composite of 2.38 indicates a real improver in this department and is based on a slight straightness of leg (-1.23) and slight foot angle 0.52, which is in stark contrast to the extreme scores of his sire Shottle in these areas. He is a maintainer rather than an improver of mammary systems, although he does offer additional teal length (1.58). Udder support, udder depth, fore udder attachment and teat placement (both fore and rear) show no or only slight positive deviations on his linear. All in all, it will be interesting to how this bull’s figures alter in the forthcoming proof runs as this UK Shottle son develops and adds daughters to his proof.

frame means he is a calv- ing ease sire at 0.6% on Direct Calving Ease. Cell count is a pleas- ing -12. As a foreign sire he has no management trait scores


available on his Holstein UK proof and of course no locomo- tion figure. However his Canadian proof indicates milking speed, daughter fertility and milking temperament all at or above average. Interestingly, as the Canadian online proofs give a vast array of information on sires, there are other bits of information that may be of use to breeders, such as the Test Day Model predictions showing that Fever daughters will become more productive as they get older, that rear udders can not only be expected to be high but also very wide (+10 Canadian), that bone quality should be fine (+10) and rear legs rear view (+13) indicates daughters will walk away from you well and not hock in. Furthermore Fever daughters should have strong loins (+8) while a number of those already scored have shown unevenness in the udder


and weakness of the crops. Fever himself was scored EX91 in June this year with an EX92 Rump. Fever is bred from an EX92 Emory, Crackholm Emory Fashion who is owned by Rocky Mountain Holsteins and has produced over 55 tonnes of milk in three lactations giving over 15,000 kg at 4.2% fat and 2.9% protein in her third in 305 days. She has bred 18 daughters with nine daughters scored and eight of those are already VG. Bred in Quebec by David Crack, her dam is a VG86 Mattie G, herself a daughter of Derianne Rudolph Karma VG86-2yrs. Fever is in fact the ninth generation VG or EX with his eighth dam being none other than A Jim Mar D Astronaut Gail EX 11*, the dam of Startmore Sterling and grand dam of Startmore Rudolph. Fever maybe new to the breeding arena and turning up the heat, but his family already has recognised stability.
