Rathgibbon Holstein Friesian Herd

Rathgibbon Holstein Friesian Herd – Gareth O’Brien and parents Francis and Ann

2019 herd average – 551kgs milk solids per cow sold to the co-op

An IHFA Laois Offaly Club feature

The ingredient mix for the successful Rathgibbon herd includes a passion for Holstein breeding, deep cow families with generations of top performance, a sprinkling of Red & White lines, a dusting of selective high index females imported from Europe, attention to detail on grassland management and the use of robotic milking on the farm.

Productivity for the herd in 2019 was 551kgs milk solids per cow sold to the co-op. This metric ranks the herd in the top 4% of all co-op suppliers. Milk volume per cow per day delivered to the co-op averaged 20.95 litres per day, ranking the herd in the top 3% of suppliers.                                                      

Currently, the herd consists of 110 cows with plans to further grow herd size to 120 cows. Producing milk all year round the herd calving pattern is 80% spring, 20% autumn. From a starting base of 60 acres, Gareth’s parents, Francis and Ann, continually re-invested in the farm over the years, incrementally developing and progressing the farm business while also rearing their family.

Today the farm size totals 200 acres between owned and rented. Pedigree registered Holstein Friesian breeding has helped to sustain farm development and expansion over the years. Gareth returned home to farm full-time in 2008 and has continued the trajectory of development ever since.

First lactation heifers accounted for 36% of the herd last year with a recorded performance average of 7,553kgs milk, 535kgs milk solids. The mature cows of fourth lactation and older, representing 20% of the herd, averaged 9,129kgs milk, 659kgs milk solids, 3.81% fat, 3.41% protein.

Currently there are fourteen cows of 5th lactation or older with twelve classified VG/EX on conformation and two cows scored Good Plus.

“I always liked good cows.” comments Gareth. While the herd had been graded up to pedigree in the 1980s, a herd depopulation ended the bloodlines of the original Friesians at Rathgibbon. The subsequent quest to put together a new herd opened up the opportunity to move in a different breeding direction.

“Through the Laois Offaly Club we became aware of Holstein bloodlines. Club officers such as Marie Lyons, Tommy Finlay, Peter Ging, Bill Flynn (RIP) and Charles Gallagher were tremendous sources of knowledge. We all learnt a great deal from them. In particular, herd visits to view the Baldonnel herd of Cyril Dowling and Mervyn Eager’s Evergrange herd were real eye-openers at the time. Having switched to Holstein breeding we noticed a yield increase straight away”.

Families in the herd today who are very prominent tracing back to those early purchases include the Sarah family from Evergrange herd and the Hazel family sourced from local club member Tony Roe.

The use of IHFA classification service has helped to develop the cow families over the years.

“Cows who classify well in attaining the top category grades do tend to last in the herd.” comments Gareth. “It makes sense in that classification rewards functionality, having such an influential weighting on udders, feet and legs, rump and strength overall. The fact that so many of the more mature cows having superior lifetime yields are classified VG/EX backs this up. Not only does classification help chart herd progress it can also be a significant lifter or morale. For example, I can remember vividly our first home-bred Excellent. She was a Besne Buck daughter from the Jenny family of Sean O’Meara. Classification also adds value by providing helpful data towards breeding policy emphasis and sire selection”.

The herd is entirely AI bred – a management strategy adopted many years ago. Current sire selection policy is to use all genomic sires, individually selected using a combination of predicted PTA’s, cow family, red and red factor lines, with polled genetics also a consideration. Recently used bulls include; Maplewood Boulder, Popeye, Magic Touch, Hotspot P, Batman and Wimbledon.

Active members of the Laois Offaly Club since the early days, Gareth says that “The club has been a fantastic forum for education and support. It helps you to keep an open mind, stimulates a quest for knowledge and further information”. They attend most of the club events throughout the year and participates in all the club competitions. The herd currently competes in the Senior Section of the club Herds Competition. Gareth has also actively served as a Club officer having fulfilled the roles of Chairman and also Treasurer in the past. Gareth has §dedicated his time to YMA, formerly serving as Chairman of National YMA for a term.

In dealing with the intricacies of robotic milking and a farm layout of three separate grazing blocks, with one such block located 5 miles from home, Gareth is all too aware of the need to up the game in grassland management accordingly. Reseeding and the replenishment of swards is a big part of farm management. Three quarters of the entire farm has been reseeded in recent years. Clover is included in every reseed mix, as a result of very favourable performance responses so far. The correct timing of all fertiliser applications is crucial as is the accurate moving of wires in accordance with balancing the moving variables of grass cover availability, growth rates, and herd demand.
