“…Implementing practices to reduce the environmental impact of livestock systems across northern Australia, while maintaining a viable level of productivity, is challenging [3]. However, when feed supplementation is incorporated to improve ruminant production then employing additives that have an effect on greenhouse gas production would be beneficial for individual producers and the industry.…”

Algae have become an area of intensive research in many fields of study. Areas of application are becoming increasingly diverse with the advent of technologies particularly in the mass production of algae biomass. Algae contain complex bioactive compounds and these are gaining importance in emerging technologies with nutritional and environmental applications. In this study, a preliminary investigation evaluated 15 species of algae from the major categories of marine and fresh water algae for their potential as inclusions in ruminant diets for management of greenhouse gas emissions. It was hypothesized that algae would positively affect rumen fermentation and gas production while reducing methane production. The hypothesis was tested using an Ankom automated gas monitoring system and rumen fluid from Bos indicus steers fed tropical forage diets. The results were variable between algae species with some showing a significant reduction in total gas and methane production, with others increasing gas and fermentation. The red and brown algae stand out as having potential for greenhouse gas mitigation with the brown alga Cystoseira having the most prominent effect. The effects observed on fermentation may be manipulated through dosage management and beneficial effects could be potentially maximized by preparing combinations of algal supplements. It has been demonstrated in this study that algae have the potential to assist in rumen fermentation management for improved gas production, and greenhouse gas abatement.

“…Raaigras heeft op zijn beurt weer een uitgebreider en dunner wortelstelsel dan de klavers (Gould et al 2016). Rietzwenkgras heeft sterkere en diepere wortels, wat van pas zou kunnen komen in het geval van bodemverdichting (Abberton et al 2008). …”

“…There has been significant progress in recent years in the production of perennial ryegrass and white clover varieties with improved forage quality characteristics aimed at improving the nitrogen use efficiency in the rumen, including traits such as water soluble carbohydrate (WSC) concentration (Wilkins and Lovatt, 2003;Abberton et al, 2008). To provide optimal nutrition for livestock from forage-based systems requires identification of appropriate plant varieties and species grown in combination that will produce nutritionally stable swards over the growing season under different management systems.…”

“…As a consequence, ammonia is absorbed by the animal rather than being captured in the rumen through microbial protein synthesis. Understanding the mechanisms and impact of such processes has been aided by selective forage breeding, which has produced a wide range of germplasm with different forage quality characteristics and agronomic attributes (Abberton et al, 2008) for use in animal production studies. For example, the IBERS perennial ryegrass breeding programme has produced ryegrasses with increased DM digestibility and elevated concentrations of WSC (Wilkins and Lovatt, 2011).…”

Animal production is a fundamental component of the food supply chain, and with an increasing global population production levels are set to increase. Ruminant animals in particular are valuable in their ability to convert a fibre-rich forage diet into a high-quality protein product for human consumption, although this benefit is offset by inefficiencies in rumen fermentation that contribute to emission of significant quantities of methane and nitrogenous waste. Through co-operation between plant and animal sciences, we can identify how the nutritional requirements of ruminants can be satisfied by high-quality forages for the future. Selective forage plant breeding has supported crop improvement for nearly a century. Early plant breeding programmes were successful in terms of yield gains (4% to 5% per decade), with quality traits becoming increasingly important breeding targets (e.g. enhanced disease resistance and digestibility). Recently, demands for more sustainable production systems have required high yielding, high-quality forages that enable efficient animal production with minimal environmental impact. Achieving this involves considering the entire farm system and identifying opportunities for maximising nutrient use efficiency in both forage and animal components. Forage crops of the future must be able to utilise limited resources (water and nutrients) to maximise production on a limited land area and this may require us to consider alternative plant species to those currently in use. Furthermore, new breeding targets will be identified as the interactions between plants and the animals that consume them become better understood. This will ensure that available resources are targeted at delivering maximum benefits to the animal through enhanced transformation efficiency.
