"steep angle and deep heel with short, well-rounded closed toes" and gives this trait a value of 3 points The thurl is given 2 points and should be centrally located between the hips and pins. The hocks set is given 2 points and should be moderate, not angled too straight, also called post-legged, nor too angled, which is known as sickle-hocked. The bones are given 1 point and should be visible and flat appearing. Pasterns are given 1 point and should be strong but flexible, with a moderate angle to the ground. Frame - 15% Frame is given the lowest level of importance on the Dairy Cow Unified Scorecard. The highest value assigned under frame is given to the rump trait at 5 points. The PDCA says that the rump should "be long and wide throughout. Pin bones should be slightly lower than hip bones with adequate width between the pins. Thurls should be wide apart. Vulva should be nearly vertical and the anus should not be recessed. Tail head should set slightly above and neatly between pin bones with freedom from coarseness." The front end is given 5 and should be smooth across the shoulder, with good spacing between the front legs. The back is given 2 points and should be strong, straight, and level. Stature is given 2 points. A cow should be proportionally correct in terms of stature. The leg bones should be long, and the stature should be consistent with other animals of the same breed and age. Other factors There are several other factors that do not fall into the four categories that are also taken into account. These traits are ranked in severity from no discrimination to disqualification of the animal from a contest. These are also given on the Dairy Cow Unified Scorecard. Breed distinctions Certain breeds are evaluated with a slight deviation from the standard scorecard. These variations are due to the slight differences between breeds, and often reflect what aspects of each breed are considered most important. Such variations include that the Guernsey breed of cattle is not discriminated based on size, and both fore and rear udder are worth 7 points each when evaluating Holstein cows. Canada In Canada, each breed is compared to a different breed conformation chart. The traits are split into 4 sections: Rump, Mammary System, Dairy Strength, and Feet and Legs. Each of the traits that
