We recommended offering a small amount of either rations to baby calves as young as 3 days of age. Calves are inquisitive creatures and generally start to nibble at concentrate feed very early on. The Milky Vanilla flavour is a great enticement for young calves to encourage early intakes. Concentrate feed aids rumen development so it is important to get calves eating early. It is important to always keep fresh feed in front of calves. Calves should be eating 2kg before they are weaned off milk.

Nuts or pelleted feed offer a complete feed in every mouthful in comparison to a blend where some sorting of raw materials may occur, particularly with young stock. Sorting can lead to inconsistent intakes and can be hard on the rumen. It also means that some of the smaller particles such as minerals are left behind.

Nuts or pelleted feed are also less attractive to birds.

A rumen buffer is something which helps to neutralise any acid build up in the rumen. Acid can build up when there is a large portion of rapidly digestible carbohydrates or starch in the diet and/or if there is not enough fibre or water in the diet.

If the diet is correctly balanced there is not much need for a buffer, however, for intensive finishing diets it is a good idea to include a buffer to minimise the risk of a digestive upset.

Actisaf Yeast is a live yeast that can alter the population of bugs in the rumen, boosting the number of fibre digesters and lactate utilisers. This leads to a more stable rumen where feed can be better digested. Actisaf is especially useful in transition diets and whereby animals are at risk of Sub Acute Ruminal Acidosis (SARA) or acidosis.

Chelated minerals are trace elements such as Copper, Selenium and Zinc which have been bound to an amino acid. They are more available to the animal as they are protected from the rumen and are up taken in the small intestine.

A lot of research has been carried out showing positive responses from chelated minerals, in terms of animal health and fertility. In areas such as this one where Molybdenum is high, using chelated copper is a benefit to the health of cattle.

We stock a range of lick buckets for cattle and sheep, Provimilk milk replacer for calves and lambs and a range of silage net and wrap.

We grow barley, wheat, oats and beans on our home farm and we also buy grain from surrounding farms. We put great emphasis on the quality of the cereal and legumes that go into our rations and we do a range of testing to ensure they make the grade.

McNamara Feeds has an in-house nutritionist to advise you on rations and feed programmes. We also offer a silage sampling service.

McNamara Feeds are fully approved by the Department of Agriculture and fully Bord Bia.

We aim for same or next day delivery, although 48 hours’ notice is greatly appreciated.

We have our own fleet of blower lorry’s, tractors and blowers and rigid lorries. We also have our own team of drivers so our dispatch team can guarantee deliveries.

The first 10 weeks of a calf’s life is the best time to manipulate the growth of dairy heifers. How we feed young calves has a knock-on effect on the success of the heifer. We should aim for close to 0.9kg ADG for calves in the pre-weaning phase. Calves should be at least double their birth weight at weaning (80kg +). It is important to weigh again at 6 months to see if your heifers are on target – Aim for 175kg by 6 months or 30% of their mature body weight. Heifers should be 60% of their mature body weight at breeding or 330-350kg. Aim for 90% of mature body weight at calving (550kg).


We deliver a minimum of 4 tonnes.

McNamara Feeds covers the greater Leinster area and surrounding counties.
