Alleviation of the heat load on lactating goats with the use of diuretics and drinking cool water.

Abstract

The effect was studied of different heat loads connected with the application of diuretics and of 10 to 15 degrees C drinking water on the milk production and some related physiological parameters of 19 Egyptian Baladi goats under experimental conditions. The increase in heat stress increased the respiration rate, rectal temperature, and serum prolactin concentration significantly, while it significantly decreased the milk production, the content of alkaline, and acid phosphatases creatinine, urea, red blood cells, and haemoglobin concentration. The diuretic Thiameterine and cool drinking water under hot conditions improved the milk yield and had a positive effect on the physiological status of the animals, especially their blood composition. The higher mill production by the goats (14.7% in the experiment) is attributed to the increased feed uptake caused by the treatments.
