Nuscience offers strategies against heat stress in cattle, poultry and pigs

tue, 1 jul 2014
The effects of heat stress are varied and are often underestimated. Heat stress affects the physiological processes of the whole animal. The following elements are recognised: increasing breathing frequency/panting, decline in feed uptake, (subclinical) rumen acidosis, decline in production in the form of growth, eggs, milk production (also in sows), and a negative effect on fertility.

For example in sows, there is a prolonged interval from weaning to oestrus, late ovulation, less clear signs of oestrus, more returnees, abortions, smaller litters, lower birth weights, autumn rejects and even an increased sow mortality rate during labour.

To prevent rumen acidosis in cattle, Nuscience has developed Mervit Buffer+. Mervit Buffer+ contains a combination of rumen buffers with live yeast. This combination ensures that cows are less sensitive to rumen acidosis during or shortly after a period of heat stress.

To improve the fertility of sows, Nuscience has developed Vitapunch. Vitapunch stimulates feed intake, causing hormone production to get going more quickly. The sows will demonstrate oestrus more quickly and clearly, which will reduce the risks of a late summer dip.

During periods of heat stress, Mervit Heatstop can be added to the drinking water or feed. A combination of various buffers, specific electrolytes and vitamins prevents the pH of the blood from changing as a result of panting and provides a supplement for electrolytes and vitamins.

If you would like to have more information on management and feeding measures to prevent the effects of heat, we will be pleased to assist you.
