“…Forages containing up to 1.85% nitrate elevated blood nitrate concentrations but did not produce any clinically adverse effects in mature non-pregnant mares [11]. However, safety studies have not been performed in pregnant mares or in growing horses, and nitrate toxicity was suspected as a cause of death and abortion in mares consuming high nitrate forages (range of 0.4 to 9.92% DM basis) [12]. In addition, it has been suggested nitrates may disrupt thyroid metabolism in horses, particularly in association with low dietary iodine levels [13].…”

Soaking can affect respirable dust particles and the concentrations of some nutrients in alfalfa and cool season grass hays. However, the effect of soaking on nitrates in hay has not been reported. The aim of this study was to evaluate the effects of soaking on teff hay, a warm season annual grass, that contained high concentrations of nitrate (>2.0%). Six bales of teff hay were used for the study. Six 0.5 kg samples were taken from each bale and assigned to 1 of 6 soaking treatments; no soaking (control), cold water immersion for 10 s, warm water immersion for 10 s, cold water soaking for 1 h, warm water soaking for 1 h, and cold water soaking for 8 h. After soaking, hay was dried, ground and submitted to a commercial laboratory for analysis. Data were analyzed by analysis of variance as a block design. When the main effect of treatment was significant (P < 0.05) means were separated by Tukey's honest significant difference test. Soaking for 1 or 8 h decreased WSC (P < 0.0001). Phosphorus, potassium, sodium, and zinc concentrations were reduced by soaking for 1 h or longer (P, K, Na: P < 0.0001; Zn: P = 0.003). Nitrate concentrations were reduced (P < 0.0001) to safe levels for horses (≤ 0.5%) by soaking hay for 1 h or longer but soaking also reduced the concentrations of some nutrients in the hay. Minimal differences were observed between cold and warm soaking temperatures.

“…Interestingly, when injecting a solution with both ions present and at the same concentration, the response (the signals obtained), is very similar in area/height and, as such, sensitivity is very close for both anions. The same methodology has been used in feed to assay hay samples (Figure 7A,B) that were presumed as the source of intoxication in horses [277]. In this case, from ten samples assayed, three (average concentrations of 92.77 ± 60.88 mg kg −1 ) and six (average concentrations of 92.13 ± 47.55 mg kg −1 ) samples tested positive for NO 2 − and NO 3 − , respectively (unpublished data).…”

studied chemistry at the University of Barcelona where he also received his Ph.D. in 2004. He worked as visiting researcher for half a year in the development of on-line pre-concentration methods using micellar electrokinetic chromatography (MEKC) at the University of Hyogo (Japan) in collaboration with Professor Terabe (father of MEKC technique). Starting in October 2005, he joined the Kyoto Institute of Technology (Japan) as a two-year post-doc researcher working with Professor Tanaka developing monolithic silica capillary columns under a

“…Nach Kenntnis der Autoren gibt es bislang eine publizierte Nitratvergiftung bei mehreren Vollblutstuten 7 , die auf sehr hohe Nitrat-Konzentrationen der eingesetzten Futtermittel, nicht jedoch auf das Tränkwasser (mittlerer Nitratgehalt 0,88 mg/l), zurückzuführen war. Diese Nitratintoxikation stand sehr wahrscheinlich im Zusammenhang mit einem Managementfehler.…”
