Drench For New Calves

Dairy Cows have a high energy requirement. In many cases, even the highest density rations will not provide adequate energy. In these situations the cow will mobilize large amounts of body fat through the liver. in an attempt to bridge this energy shortfall. This results in ketones accumulating in the blood, milk, and urine. What can follow, is referred to as ketosis or acetonaemia. propylene glycol (PG) is metabolised in the rumen and liver and affects metabolites, hormones, liver composition, feed intake and milk production. PG helps prevent excessive fat mobilisation and imbalances in carbohydrate and fat metabolism and thereby reduce the risk of ketosis.

PG decreases plasma concentrations of non-esterified fatty acids (NEFA) and beta-hydroxybutyrate (BHB), especially in early lactating cows with relatively high levels of NEFA. PG also reduces the triacylglycerol (TG) content of the liver and the concentrations of ketone bodies in milk and hence, has anti-ketogenic properties. For cows in early lactation PG tends to increase milk yield and reduce milk fat percentage, while milk protein percentage is unchanged. Thus, PG has no effect on energy corrected milk yield (ECM).

LDS Propylene Glycol will provide an immediate, and concentrated energy source which will reduce body fat accumulating in the liver. Some herds use LDS Propylene Glycol as part of their routine Dry Cow management. In other herds it is only used when animals are perceived to be ‘at risk’.
