El rodeo Braford que se maneja en esta Unidad experimental, por la participación de sangre cebuína en el mismo, presenta diferencias fisiológicas con las razas que se han manejado tradicionalmente en el país. El ajuste de las prácticas de manejo ha buscado mejorar la eficiencia de las diferentes categorías que integran el rodeo de cría:
terneros, vaquillonas de reposición y vacas de cría. En años sucesivos se han venido registrando buenos comportamientos reproductivos y el objetivo de los trabajos
más recientes es ajustar las prácticas de manejo de modo de implementar las medidas de acuerdo a los requerimientos de las diferentes categorías, buscando disminución de los costos. Los resultados que se presentan pertenecen al rodeo de la Unidad, constituido por 294 vacas entoradas y sus correspondientes reemplazos, que se maneja en un área de 500 ha., que cuenta con un área de mejoramientos de diferentes edades que alcanza al 15%. La pequeña área de verdeos anuales es asociada con leguminosas para la instalación de las mismas. El sistema productivo es exclusivo de cría, a efectos de disminuir la carga para el período invernal se realiza la
extracción en verano-otoño. Los terneros machos en abril y las vacas de descarte en dos etapas, las vacas usadas que no serán entoradas nuevamente se destetan precozmente y son invernadas en verano y las restantes apartir de abril luego del diagnóstico de preñez. |

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:
