negative Cell Count, posi- tive Daughter Calving Ease (making him suitable for use on heifers), and a positive Fertility Index. All these are coupled with an excellent Temperament score of 2.67 and a plus Milking Speed of 1.31. The only flaw from a management perspective is a slight negative on Condition Score of -0.75. Bluesky seems to offer breeders many of the type traits
that both his dam and sire excelled at. Bluesky daughters are currently showing above average stature (2.01) with depth of body (1.18) and a dairy frame (1.76 angularity). If breed- ers are looking specifically to improve chest width, rump angle or rump width then Bluesky lacks the ability to do this, rather than being weaknesses for the bull he merely shows
little deviation on these particular traits. However he does excel in udder improvements. All the mammary traits show a strong tendency to the right on his linear, in particular snug fore udders, high rear udders and shallow udders anticipated in his daughters. Teat placement both fore and rear is around the one devia- tion point, while there is a pleasing spread from front to back, shorter teats (1.29) and a defined ligament (1.15 udder support). The only area left is therefore feet and legs with Bluesky leaning towards his sire in terms of leg straightness (-1.32), coupled with 1.07 foot angle and a very promising locomotion score of over 2. Bluesky was so named because of the summer’s day on which he was
born. Although a little short on reliability at this stage, there is a fair chance that on British soil breeders may find their own ray of sunshine when they calve his daughters into their own herds.
CORRECTION In the October Road Test on Crackholm Fever, the impression was given that some
of his daughters have shown unevenness in the udder and weakness in the crops. In fact, the opposite is true and Fever’s proof shows that his daughters are better than average for these traits. We apologise to all for this misinformation and are happy to correct it.
UK £PLI leader, an Oman son, are examined this issue
without extremes, an improvement in cleft definition would be the most obvious trait at 1.76 on udder support but all traits in the mammary are between 0.5 and the aforemen- tioned 1.76. As a foreign tested sire without UK milking daughters, he
has neither a Locomotion score nor a Condition Score for his daughters and he rates average in his country of origin, the USA, for both milking speed and temperament.
There is no doubt this bull has been one of the most sought-after and favoured Oman sons and he is backed by a 13,363 kg (305 day) Aaron dam, Winning-Way Marci VG89 who tested at 4.4% fat and 3.5% protein in the same lactation. She in turn was from the VG85 Peticote Bwood Mozzetta with the third dam being a Mascot daughter, with a three generation pedigree of high production sires. He has been used heavily as a flush sire, the majority of his UK registered sons and daughters are so far the result of embryo transfer (85%) and a third (seven) of his 21 registered progeny at the time of writing are ET bulls. Man-O-Man offers a solid linear with high production, great components and desirable management traits and is likely to see continued use if his figures and daughters continue in the same vein.
