heifers of which all have classifi ed Excellent and have formed a solid base to this family in the herd. “The Bevin family is another bought in family from a purchase at the Joelee sale. This line is breeding females that I really like and that are developing in to good cows. “There are many individuals that are standing out in the herd at the moment, including Aireburn Miss America VG87 calved her second in February having given 12,545kg at 3.75%bf and 2.99%p as a heifer. Another pleasing second calver is the VG86 scored Aireburn Sam Sarah 2, she is out of an EX91 dam by Dragon.
“Each year the heifers we calve in are getting better. Aireburn Fever Trifolium VG87 is a heifer that is the type we like to work with, this family was one we re-introduced after losing it completely. She is the fi fth generation of VG or EX and is out of an EX90 Shottle dam from the Tewitthall herd. Another fresh heifer I like is Aireburn Seagual Bevin, an October 2012-born heifer
ABOVE LEFT Dunnerdale Stormatic Aldina EX95 is now in her eighth lactation and has given over 70t lifetime to date. She has nine descendants in the herd.
ABOVE RIGHT Aireburn Sam Miss America 3 is a fresh second calver, classifi ed VG87 is out of an EX92 scored Convincer dam.
BELOW Aireburn Dramatic Linda is an EX92 scored seventh calver by Shadow-Ridge Dramatic and is out of a cow purchased from Brimmoor.
out of a VG88 scored Shottle.”
Over the years many proven bulls have been used in the herd, but there are few that would be used again. “I like to keep moving on with genetics and it is only the exceptional bull that I would go back to use again. Shottle has defi nitely been the most infl uential bull, he has done a good job on any cow and he is one that I’ve used time and again. “Goldwyn and his sons have had an infl uence and Mr Sam also worked well in our herd. Historically, Warden was a bull that changed the herd from the original Friesian herd and moved it on to a bigger framed dairy cow, but also cows that could breed well,” he explains. “We are looking to raise the PLI of the herd and move genetics on so we’re using 50% genomic sires to help achieve this. Although I am happy with what I’ve seen of genomics so far it is still early days. I can see Genomics will play a major part in moving the breed on and the advance in the next 10 years I think will be tremendous, but by chasing numbers the gene pool is tightening quickly. We are conscious to select genomic
