Technical Abstract: Ingestion of small amounts of condensed tannin by ruminants can produce valuable outcomes such as improved nitrogen use, reduced bloating and methane output, and internal parasite reduction. Many grasses and forbs have little if any condensed tannin in them. Not all livestock will consistently consume solid supplements while grazing especially when grazing high quality forage, but they all usually drink water each day. Also, not all condensed tannins have similar effects on ruminants. Therefore, eight lambs with the same initial weight of 43.1 kg were individually penned, fed alfalfa pellets twice daily, and had ad libitum access to two liquids. Liquid intake was measured daily. After an adjustment period to pens, feeding, and watering conditions and water with condensed tannin in it, three sequential week-long trials were conducted. In Trial 1, lambs chose between normal water and a quebracho tannin-water mixture of moderate concentration (ca. 1% DM intake). In Trial 2, lambs chose between normal water and a quebracho tannin-water mixture of lower concentration, and in Trial 3 lambs chose between a quebracho tannin-water mixture and a wattle tannin-water mixture with both of the same concentration. In Trials 1 and 2, they had inconsistent intakes of tannin water and normal water from day to day (P = 0.02) and neither preferred nor avoided tannin solutions when they had normal water to drink. They also had inconsistent intakes of the two tannin solutions (quebracho and black wattle) offered simultaneously (P = 0.01), and generally showed no preference for either tannin solution when offered only the two tannin solutions to drink (P > 0.15). Results support other observations that sheep and cattle will voluntarily consume water with small amounts of condensed tannin in it, and provide no evidence that sheep prefer consuming small amounts of quebracho versus black wattle tannin in water.
