The Sires of Sons for the Jersey breed in 2021
In 2021, there were 129,213 animals recorded by the American Jersey Cattle Association. Those animals were sired by 3,359 different bulls (3,212 recorded sires). Which bulls are used most widely? Who are the leading sires of sons?
A total of 61 bulls sired 10 or more sons registered in 2021. In total, these bulls sired 36% of all Jerseys—male and female (46,525)—and 59.1% of all males recorded (2,754) during the year. The 40 bulls siring 10 or more sons are listed below.
Studying the top 10, 20 or 30 of these bulls is important for two reasons. First, they are largely determining the breed’s production capability in the near future. Second, they are going to continue to exert their influence upon the breed’s genetic merit for production and functional fitness for many years through their registered sons. For the past several years, it has been trending towards GCode bulls making up a large part of this group. However, this year we also see proven sires like “Listowel-P” and “Chrome” among the top 10.
The relative genetic contribution of the 61 sires with 10 or more sons to the genetic pool for 2021, is indicated by the weighted average (bottom line of the table). The average GJPI is +87 of the sires and they have a +3.0 Productive Life (PL) and are +6.1 for GJUI. This average is higher than the raw average of their PTAs. The bulls with the highest PTAs are contributing the most to the average genetic merit of sons registered in 2021.
Bulls by Group
The top 10 bulls ranked by the number of sons registered sired a total of 12,994 offspring, of which 658 were sons. The group carried the highest GJPI average at +125 and averaged +627 for PTA Milk; $573 Cheese Merit Dollars; and $561 for Net Merit dollars. Other averages are +4.1 for PL, and 82% Reliability. This is the fourth year for “Chrome” to rank among the top 10 sires of sons.
The second group of 10 sires, was very similar to the first group in traits and carries the highest PTA Milk of +781 and +108 GJPI. The group sired 313 sons and 10,046 daughters.
The last two groups of bulls are made up of an even mix of high production and high type bulls with more than 400 registered sons.
* Bulls included are Generation Count 4 or higher with a BBR 94 or above.
