Valerie Brady runs an 80-cow dairy herd - split between winter and spring calving - across a 60-acre milking platform in Mullahoran, Co. Cavan.
Cows averaged 7,500-litres in 2017, with a concentrate input of 1.5-tonnes/cow as part of a diet designed by Kiernan Milling - a company that Valerie has been working alongside for the past number of years.
Conor McCaffrey B.Agri.Sc - Technical Sales explained the process involved: "Before formulating any diets, I call out on-farm. Valerie and I go through the cows and assess body condition score and I also take a silage sample for analysis in our own in-house lab."
Valerie went in search of a formulated diet that would suitable for the entire herd at various stages of lactation including freshly calved cows to support thirty-litres of milk per day.
The Cavan farmer's 29% dry matter silage (the amount of silage material after water has been removed) has a DMD value of 78%.
"I knew from the offset that this silage could support in or around 10/11-litres plus maintenance before concentrates were ever introduced."
"In order to sustain this level of production, I knew that I needed to get 21-and-a-half UFLs into the cow on a daily basis to avoid stripping excess conditions off their backs."
Two weeks into the diet, the cows are producing about 28-29-litres, 4.8% fat and 3.54% protein; Valerie is impressed with results:"The cows are milking very well and are showing heats at present." Valerie concluded.
