A new Normande TPI with a stronger emphasis on beef value, functionals, and a new composite for feet & legs
The French Normande Association (OS Normande) along with the Selection Centers and the National Livestock Research Unit introduced a new ISU (the French TPI) in 2018. This new ISU (TPI) tips the criteria balance towards beef value and functional traits (more specifically udder health, fertility and feet & legs). A new beef value composite index has been developed. combining newly analyzed veal and steer quality traits as well as the previous muscularity and frame indexes. See below a comparison between the 2012 ISU with the new 2018 one. To the right is the 2012 ISU with English terms and a slightly different sorting of the various traits. More information to come.
The production share has been reduced to 26% and the formula is entirely based on almost equal quantities of lbs of protein (14%) and fat (12%) as opposed to privilege protein in the previous index. Udder health, which has been given a much larger share, by combining the somatic cell count and the new ‘clinical mastitis’ index. Fertility has also received a boost and is now a composite index made of the new ‘calving-1stAI interval’ index and the previously introduced cow and heifer fertility indexes. Finally, udder and feet & legs get the lion share. In addition, the Feet & Legs index is the composite of more criteria such as locomotion, bone quality, etc…In conclusion, with this new TPI, the Association is developing a much better, sounder Normande cow. There are talks about including calving ease and genetic variability in the future, as well as developing a specific grazing TPI. But the newly revised criteria should confirm your choice of the Normande for its sustainable and added value qualities.
Here is the break down of the new TPI:
ISU = French Normande TPI = 26% production (12% F + 14% P) + 21.25% type (4.5% muscularity + 3% frame + 6.5% feet & legs composite + 7.25% udder composite) + 12.5% veal & steer value + 16% udder health (9.5% cell + 6.5% mastitis) + 13.5% fertility + 6% longevity + 4.75% milk speed
Feet & Legs = 30% rear legs rear view + 23% rear legs side view + 20% locomotion + 16% bone quality + 11% foot angle
Beef value composite: 15% frame + 22.5% muscularity + 11.25% veal growth + 10% veal conformation + 2.25% veal color + 11.25% steer growth + 27.5% steer conformation (Note: muscularity and frame reflect the beef value of cull cows)
Production = Protein (14%) and Fat (12%)
Udder Health = 50% Somatic Cell Count + 50% Clinical Mastitis
Fertility = 50% Fertility Cows + 25% Fertility Heifers + 25% Calving-1st AI Interval
Type = 45 % Udder + 25% Feet & Legs + 15% Frame + 15% Muscularity
Udder = 25% Udder Depth + 20% Ligament + 20% Udder Balance + 15% Front Teat Placement + 10% Fore Attachment + 5% Rear Udder Height + 5% Teat Direction
Frame = 30% Chest Depth + 30% Chest Width + 30% Rump Width + 10% Stature
Muscularity = 25% Top + 25% Loin + 50% Round

A few tips to understand our proofs
ISU = French Normande TPI = 26% production (12% F + 14% P) + 21.25% type (4.5% muscularity + 3% frame + 6.5% feet & legs + 7.25% udder) + 12.5% veal & steer value + 16% udder health (9.5% cell + 6.5% mastitis) + 13.5% fertility + 6% longevity + 4.75% milk speed
Beef value composite: 15% frame + 22.5% muscularity + 11.25% veal growth + 10% veal conformation + 2.25% veal color + 11.25% steer growth + 27.5% steer conformation (Note: frame and muscularity reflect the beef value of cull cows)
Feet & legs composite: 30% rear legs rear view + 23% rear legs side view + 20% locomotion + 16% bone quality + 11% foot angle
Sire and daughter calving ease: average equals 89. 90 is a better calving ease; 88 is less calving ease.
For all criteria below, “0” is optimum.
• rump angle: + is sloped.
• back line: + is curved up.
• rear legs side view: + is posty.
• rear legs rear view: + is straight.
• foot angle: + is steep.
• udder balance: + is high rear quarters.
• teat direction: + is internal.
Functional traits: positive values are desirable for all.
2020 yearly rolling base adjustment
Each year, France does three proof calculations and readjusts its rolling base once with the first proofs of the year. The rolling base is the population of cows from which indexes are calculated. Since the genetic level of the base increases as the population itself changes, all indexes naturally drop. In contrast with France, the United States recalculates its base every five years (last adjustment: 2020). Numbers have consistently been good over the past few years for the Normande. Once again, the Normande has a higher increase than the all other French dairy breeds (Holstein, Montbeliarde): 97 lbs. for milk, 5 lbs. of fat, 4 lbs. of protein,. This means a bull whose milk index drops in this release by 97 lbs. actually remains stable in relation to the population. A smaller drop would indicate an improvement, while a deeper drop would point to deterioration. %F increased by .004 and %P by .009. The udder composite improved by .08 and the feet & legs composite by .01. The muscularity remained stable. The change in the rolling base indicates that the Normande population is improving and the selection program is efficient.

Complete and current indexes for all Normande bulls, past and present
The French Animal Production Institute’s website will provide you information on all bulls, including very old ones. The pages are in English, but you may find some terms or abbreviations to be different from the ones we use.
Please note that all breeding values are in kg (1 kg = 2.2 lbs) and % are 0/00 (for F% and P%, please divide French numbers by 10 to get the % value). Feel free to contact us if you have any question.
