Impacto de la Calidad de Agua para Bebida Animal en Relación a Parámetros Productivos, Composicionales y Reproductivos

Eighteen multiparous lactating grazing Holstein cows, 9 ruminally cannulated, average 136.1 +/- 14.6 days in milk, were randomly assigned to three treatments consisting of water containing different levels of total dissolved solids (TDS; mg/l): Treatment 1 = 1,000; Treatment 2 = 5,000 and Treatment 3 = 10,000, at the Experimental Dairy Unit at Rafaela Experimental Station (31 degrees 11'S latitude) during summer 2005. Animals were arranged in a randomized complete block design with three 28-day experimental periods, with 3 weeks for water adaptation and 1 week for measurements. Feed and water intake, milk production and composition, body weight and condition score and rumen parameters were evaluated. No treatment effects were observed in any of the variables evaluated, with the exception of water intake, which was higher for animals receiving 10,000 mg/l TDS in the drinking water (189 l/day vs. 106 and 122 l/day for cows receiving water with 1,000 and 5,000 mg/l TDS, respectively). Water intake was significantly higher for animals in treatment 10,000 (P < 0.05). It was concluded that the rumen presents a surprising buffer capacity and that consideration of TDS alone is insufficient to characterize drinking water quality.

“…A similar situation was found in large areas of the Central Santa Fe milking region (Revelli et al 2002). In the latter, 53% of the samples taken from dairy operations were considered unsuitable for lactating dairy cows and, therefore, were not recommended for animal intake.…”

“…The increase in the levels of minerals in the milk can modify the organoleptic properties of the milk, mainly causing a more pronounced flavor of the product, and thus harming its commercialization [ 35 ]. A pronounced flavor was not observed in this work, as a favorable result was found for the sensorial characteristics of the milk of animals that were raised in regions where the means of the total dissolved solid levels of the groundwater were within the same range as those studied here.…”

Due to its necessity and magnitude, water is essential for animal nutrition. This study aimed to evaluate the effects of increasing levels of water salinity on the quality of goat milk in the Brazilian semiarid region. Twenty-four multiparous Alpine goats, with an average live weight of 38.0 ± 4.0 kg and an average lactation period of 30 days, distributed entirely at random, were used. The experiment lasted 64 days including an initial period of 14 days of adaption to the diet. The experimental treatments consisted of water with different levels of total dissolved solids (TDS): 640, 3188, 5740, and 8326 mg L−1, obtained using sodium chloride (NaCl). Increasing the levels of TDS in drinking water from 640 to 8326 mg L−1 did not significantly (p > 0.05) affect the production and the physicochemical composition of the milk. There was a linear increase (p < 0.05) in the water consumption and acidity variables as a function of the total dissolved solid levels. The mineral composition of the milk was not altered with increasing levels of TDS in water from 640 to 8326 mg L−1. There was no negative effect (p > 0.05) for any of the sensorial attributes analyzed in relation to the treatments. Therefore, as a general conclusion, based on the analyses carried out in this experiment, it was found that water with total dissolved solids, when supplied for short periods of up to 48 days, does not alter the production, physicochemical characteristics, or the organoleptic properties of goat’s milk.
