Regulation of fluid balance in goats and sheep from dry areas

Olsson K., Dahlborn K., Benlamlih S., Hossaini-Hilali J.

Food and water intake are closely linked. Enough drinking water is a prerequisite for animals to utilize food efficiently. Goat and sheep breeds which are native to dry regions have developed strategies to cope with scarcity of food and water. However, animals from temperate regions may encounter problems in adjusting to a dry environment. This is obvious during late pregnancy and lactation, when the strain on the fluid regulatory mechanisms becomes more severe. In our studies we have found major differences in the capability to cope with shortage of food and water between the Moroccan black goat and the Swedish high-yielding domestic goat breeds; e.g., the Moroccan goat having a lower water turnover and higher thirst threshold. Likewise, the Sardi and D'man sheep breeds respond differently; the Sardi being used to harsh conditions endure both food and water deprivation better than the D'man sheep, which are kept in the oasis. Thus, it is important to consider the response of each breed to different challenges in order to select the most suitable one for production in a certain environment.
