Managing the Replacement Heifer Calf to Weaning

Calves. They become heifers. They become cows. After all, that’s the point… to raise healthy, productive animals that become part of the dairy herd. From a financial perspective, it’s important that we invest enough in our heifers for them to grow at the proper rate and enter the milking herd at the right size and age. The future profitability of the dairy herd is dependent on the success of the heifer rearing program.

Blindness, CCN and PEM

CCN is a condition affecting growing cattle (up to 18 months typically) and sheep of all ages, tending to occur in outbreaks and is associated with high concentrate rations, Low roughage diets, including lush grass which is high in sugars but low in structural fibre which is associated with Sub-Acute Ruminal Acidosis and acute Acidosis. The condition has been associated with well-nourished calves that have been left hungry or find themselves on a poorer plane of nutrition suddenly.

Silage Stocks Tightening

The recent heavy rainfall has meant that grazing conditions are very difficult on many farms, very little fertiliser has been spread and a lot of stock are still fully housed. Consequently, silage stocks are starting to tighten on many farms. Farmers are encouraged to:

Trace Element Supplementation at Grass

Mineral imbalances and deficiencies are quite common in Irish grazing situations, while supplementation at grass can prove difficult, especially where little or no concentrate supplementation is fed.

Mineral imbalances may be noticed in isolation or in combination. Imbalances of major elements may cause rickets, lameness, milk fever, lambing sickness, tetany, reduced appetite, reduced milk yield and depraved appetite. While deficiency of trace elements may cause ill-thrift, abortion/placental retention, perinatal calf death, reduced immunity in calves and cattle. Susceptibility to bacteria and parasites, infertility in cows, reduced fertility in bulls, lowered milk yield, lameness, slow healing of wounds and poor skin/hair quality.

Calcium and Magnesium’s Critical Role in the Transition Period

Most dairy farmers are now in the midst of calving and as such their cows are in the Transition Period (3 weeks pre-calving to 3 weeks post calving)

Managing the dairy cow during the transition period to minimise metabolic disorders and maintain high levels of immunity is critical for optimising fertility, milk yield and quality in the next lactation.

In the pre-calving transition period the objective is to minimise sub clinical and clinical milk fever (also known as the gateway disease) and this is achieved by minimising the amount of Calcium in the dry cow diet along with the addition of 30 grams of magnesium and 30,000iu’s of vitamin D3 per day

Dwarfism – Small Calves

A number of farmers in the west of Ireland have asked for assistance in relation to calves being born very small, with weak legs and joints, and in extreme cases being malformed. More often than not this is as a result of a trace element imbalance, often caused by antagonists in the soil which can prevent the uptake of trace elements such as Copper, Zinc, Selenium, Iodine or, more specific to the cases being spoken about here, Manganese. Phil Rogers, MRCVS, retired from Teagasc Grange describes this phenomenon as follows:

Mastitis Control Program

In an average 100 cow herd, 25 cows can have clinical mastitis per year. Each affected cow has an average of 1.6 cases of clinical mastitis per year, therefore in a 100 cow herd there is approximately 40 cases of clinical mastitis per year.
