Abstract
This paper describes three strategies to improve the reproductive performance of small ruminants
in ways that lead to ?clean, green and ethical? animal production. The first is aimed at control of the
timing of reproductive events for which we turn to the socio-sexual inputs of the ?male effect? to
induce synchronised ovulation in females thatwould otherwise be anovulatory. The second strategy,
?focussed feeding?, is based on our knowledge of the responses to nutrition and aims to develop
short programs of nutritional supplements that are precisely timed and specifically designed for
individual events in the reproductive process, such as gamete production, embryo survival, fetal
programming and colostrum production. The third strategy aims to maximise offspring survival
by a combination of management, nutrition and genetic selection for behavior (temperament). All
of these approaches involve non-pharmacological manipulation of the endogenous control systems
of the animals and complement the detailed information from ultrasound that is now becoming
available. The use of such clean, green and ethical tools in the management of our animals can be
cost-effective, increase productivity and, at the same time, greatly improve the image of meat and
milk industries in society and the marketplace. |

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:
