Water with different salinity levels for lactating goats.

Water with different salinity levels for lactating goats.

The aim of this study was to evaluate the influence of supplying water with varying salinity levels to dairy goats on nutrient intake, apparent nutrient digestibility, and milk yield. The experiment lasted 65 days and involved 24 crossbred goats with mean body weight of 38±4 kg, which were randomly allotted. It was set in a completely randomized design with four treatments consisting of 640, 3188, 5740 and 8326 mg L‒1 total dissolved solids (TDS) in the drinking water. The results showed that water salinity levels had no effect on the intake of dry matter, neutral detergent fiber, crude protein, ether extract, total carbohydrates, non-fibrous carbohydrates, total digestible nutrients, metabolizable energy, digestible energy, or apparent nutrient digestibility. Water intake was influenced by the salinity, increasing as the salt level was increased. Moreover, the varying salinity had no significant effect on milk yield. Drinking water containing up to 8326 mg L‒1 TDS provided no interference with the intake and nutrient digestibility of lactating goats in the feedlot. However, increasing the water salinity affects animal intake without any changes in milk yield. Therefore, this type of water can be used for crossbred goats at 30 days in milk, for up to 65 days in the feedlot.
