Abstract:
The lactational performance and fertility of high yielding Friesan dairy cows in a hot desert climate were analysed for summer and winter differences. The herd is situated in the Negev desert of Israel.Contrary to all previous reports,milk yield was significantly higher in summer than in winter; furthermore fertility was not lower in the hot months. The daily range in summer temperature was from 22° to 40°C and in winter from 8° to 22°C.The results are discussed in terms of the management and feeding practice of the farm. It was suggested that the cows had been acclimatized and that their thermoneutral zone has been raised. © 1968 N.V. Swets & Zeitlinger.
