Semex's multi-million dollar investment in genomic testing has once again borne fruit in the latest proof run, with the company's sires once again dominating the genomic league table.  The firm has 24 of the yop 50 sires ranked on UK TM, 10 of the top 25 sires and five of the top 10. Of  those there are 19 sires with a TM of 3.50 or over. On the PLI ranking Semex has 26 sires in the top 100 available - significantly more than any other company. Star performers include Velthuis SG Athens, who has a TM of +4.44 and who missed out on the top type spot by just 0.01 of a point. In 3rd position is Wa-Del Bryant at +4.43, with the elite-status Immunity+ sire Val-Bisson Doorman at +4.07 at sixth position. Other top ten ranked sires include the newcomers Silverridge Avalanche, at +3.98 and Croteau Lesperron Urbain at +3.94. Heading Semex's range on the PLI list is another exciting new sire - Mr Delicious Lionel. He is  a son of McCutchen out of a Robust daughter, and thus a generation ahead of many of the sons of Robusr on the PLI list. "He has probably the most modern pedigree around," says Willie Tait, Semex UK genetics manager. "He baosts very high PLI and milk, excellent daughter fertility and low SCC. All combine with great overall type to make him an excellent all-rounder." "Semex is genomically testing over 5000 sires a year, and only a small percentage of the top ones make the grade," adds Mr Tait. "The fact that sons of genomic sires are being introduced before their sire gets a proof shows the speed of genetic gain that genomics is bringing." The large number of bulls tested also allows for a wide diversity of sire to made available, including sons of Numero Uno (Bombero and Urbain), Shamrock (Loberry), De-Su Pierre (Locarno), Armitage (Zanzibar) and Mogul (Ste Odile Pure and Comestar Lineman).

Semex has introduced three new genomic sires to its range, including a new sexed Immunity+ sire. This take the number of sires being marketed in the UK for its exclusive immunity-boosting range of sires to 20.

The new Immunity+ sexed sire is Lexvold Teddy -  a Superstition son whose dam is by Man-O-Man with her pedigree extending back to the legendary Dellia herself. His genomic proof gives him scores of +2.81 for UK TM, +2.40 for Mammary and +2.59 for Feet & Legs. With a milk figure of +746kg, expect his daughters to be high producing, tall, strong dairy cows with exceptional feet, legs and udders. With a SCC score of -16, he will help reduce cell counts keeping milk price higher.

Also available sexed is Kellercrest Lancome, who has been extensively used as a sire of sons by Semex. He is an Epic son from Kellercrest Manoman Lacy VG-85-2yr. Significantly there is no Shottle, Planet, Goldwyn or Bolton in his dam's pedigree, with Shottle three generations back in his sire's pedigree. As a result he will feature high on the list of choices for herds which have used these sires extensively in recent years. His predicted proof puts him at +2.91 for UK TM, +2.83 for Mammary and +1.98 for Feet & Legs. His daughters will be medium-sized with shallow, strongly-attached udders and excellent feet. Functional traits are good, milk and PLI are high, and he is also -16 for SCC.

Richmond-DF El Bombero is sired by one of Semex' most popular sires in recent years - the Immunity+ sire Amighetti Numero Uno - and is out of a Superstition daughter. He is very high PLI at £256; has very high milk, low SCC and high daughter fertlity (+0.3). His daughters will be well-balanced, combining plenty of width with ideal dairyness. His attributes all add up to produce long-lasting cows, which ar shown in his very high Lifespan and Herd Life scores.

"All of the sires are extremely complementary to the others in the Semex range and will ... Read More...
