The concentrate energy trigger for dairy cows and calves

Pro 90 in its different forms, when fed as part of a structured feed programme, is a highly cost effective product, especially so where the farmer is looking to successfully manage a high forage feeding system. At calving, cows suffer from a severe drop in blood glucose which depresses appetite and affects liver function. A cow yielding 30 litres a day needs 2000g of glucose per day. The most she can obtain from food and its resultant metabolism is 1300g. The balance drawn from tissue reserves.

"Glucose is the first component of milk production as supplies are drawn from blood at the first stages of milk synthesis. Low levels of blood glucose probably cause the brain to release chemicals of stress. These chemicals have been shown to affect liver function, causing fatty liver. Producers must acknowledge the risk they run by neglecting the energy gap."

Physical Parameters

1. Stimulates overall dry matter intake, principally forage, hence increased energy and protein supply.

2. Enables efficient and importantly, safe mobilisation of body fat reserves for milk synthesis, without the formation of ketone bodies in the liver, or high betahydroxybutyrate levels in the blood.

3. Trials in the UK and Northern Europe have demonstrated an average 5.7% response in lactation yield. This is primarily due to greater persistancy of yield in mid/late lactation.

4. Largely controls clinical and most importantly the largely undetected sub-clinical Ketosis, which consequent reduction in yield.

5. Improves vitamin absorption because vitamin solubility is enhanced with fat based products like propylene glycol. Furthermore, microbial activity in the rumen is improved in relation to fibre digestion, i.e. more efficient use of grass/silage.

6. There are positive benefits in terms of fertility and conception due to the complete and efficient conversion of fat reserves. Where fat mobilisation is incomplete, interference with the reproductive cycle is frequently apparent.

7. PRO-90 components rapidly convert to blood glucose, which in turn stimulates production of growth hormone, which it is well established has a direct benefit of increasing milk yield.

8. Where PRO-90 is fed, due to the removal of stress factors as indicated above, there is noticable awareness of general well being and herd health.

Feeding and Trials

Pro 90 Dairy is available in liquid and meal form and is recommended to be fed for six weeks post calving.

liquid at 0.15 litre/cow/day
or meal at 0.5Kg/cow/day

Alternatively Pro 90 Dairy can be fed at 0.10 litre/cow/day rate for the first 100 days of lactation.

Dry Cows

This group should be fed PRO-90 DAIRY for two to three weeks pre calving at half rate. Feeding at this level will stimulate liver function, enhance forage intakes and prepare the cow for lactation.

NOTE: For treating cows under stress, the liquid can be used as a drench at 1.0 litre/day.

The trial group required 0.67 fewer services (29.9%) and conceived 21.1 days earlier. Blood B-BH Butyrates were 1.295 in the control group and 0.963 in the Trial Group. This can relate to returns of £70 - £94 per cow.
