Abstract:
Context: Early sown, annual ryegrass pastures and winter crops provide a high-quality feed for livestock and also have a high water content during autumn and early winter compared with typical temperate pastures.
Aim: We hypothesised that beef cattle grazing annual ryegrass or forage oats would not need additional access to drinking water to maintain their intake and growth.
Methods: In Experiment 1, 48 weaned, castrated male Hereford calves with liveweight 154 kg (±6.7 kg; s.d.) grazed Italian ryegrass at a daily allowance of 4.5 kg dry matter (DM)/100 kg liveweight in two treatments including with or without access to drinking water. In Experiment 2, 60 Hereford steers with liveweight 382 kg (±20.6 kg; s.d.) were offered a daily allowance of 5 kg DM/100 kg liveweight of forage oats in a 2 × 2 factorial design either with or without access to drinking water and with or without sorghum grain silage supplemented at 1% of liveweight. The experiments were analysed as a completely randomised design, with individual pasture plots as the experimental unit.
Key results: Daily growth rates of calves in the two treatments were similar (P > 0.05); however, calves with access to drinking water consumed 60% more water than did the calves without drinking water (P < 0.001). Access to drinking water had no effect (P > 0.05) on the daily growth rate of steers (P > 0.05); however, the daily growth rate of supplemented steers was 9% higher than that of the unsupplemented steers (P < 0.05). Total water intake was affected by access to drinking water (P < 0.005) but not access to supplementation (P > 0.05).
Conclusions: Both calves and steers derived no production benefits by having access to drinking water when grazing actively growing annual ryegrass pasture or forage oats. Nevertheless, livestock should be monitored closely so that appropriate interventions can be made if there are changes in the pasture availability or weather.
Implications: Grazing early sown winter forages by livestock can help circumvent the autumn?winter feed gap and these forages can be utilised more cost-effectively by not having to provide drinking water when the DM content is low. MenosAbstract:

RESUMEN.
Las frutas y hortalizas pueden contener contaminantes que llegan al producto en cualquier punto de la cadena productiva. En este sentido, se debe controlar la acumulación de elementos potencialmente tóxicos como arsénico (As), cadmio (Cd) y plomo (Pb) para asegurar y controlar la inocuidad de estos alimentos.
Con el objetivo de monitorear los contaminantes inorgánicos, de forma rápida, confiable y con métodos analíticos en acuerdo con los principios de la química verde, se desarrolló y validó una metodología para la extracción simultánea de estos elementos asistida con microondas, en un solo paso y utilizando ácido diluido.
Se aplicó el método validado a cuatro productos: zanahoria, lechuga, manzana y tomate. Los parámetros de desempeño de esta metodología indicaron que resultó adecuada para monitorear estos alimentos tomando como referencia la reglamentación vigente y que todas las muestras analizadas cumplieron con los criterios establecidos. Esta metodología validada puede ser considerada como alternativa a los métodos estándar de análisis de As, Cd y Pb en este tipo de alimentos. El desarrollo de estas herramientas analíticas es de relevancia y deja disponible una plataforma analítica al servicio del sector productivo y de organismos de contralor nacional.
ABSTRACT.
Fruits and vegetables may contain contaminants that reach the product at any point in the production chain. In this sense, the accumulation of potentially toxic elements such as arsenic (As), cadmium (Cd) and lead (Pb) must be controlled to ensure food safety.
In order to monitor inorganic pollutants, a fast and reliable analytical method also following the principles of green chemistry was developed and validated for simultaneous extraction of these elements using a microwave-assisted procedure, in a single step and with diluted acid. The validated method was applied in four products: carrot, lettuce, apple and tomato. The figures of merit of this methodology indicated that it was adequate to monitor these contaminants in the analyzed foods fulfilling with the current regulations. The developed method can be considered as an alternative to standard methods for the determination of As, Cd and Pb in these foods. These kinds of studies applied to monitor food safety are relevant and, in this case, an analytical platform is now available for the productive sector and national control agencies. MenosRESUMEN.
