Xylanase is an enzyme that breaks down xylan, a key plant cell wall component, into simpler sugars. In weaned pigs, whose digestion is still maturing, xylanase supplementation aids in breaking down fibrous feed, enhancing nutrient absorption.

This study investigated the effects of AM/PM feeding on free-range laying hens via several welfare, behaviour and health parameters. The AM diets (12.5 MJ AME/kg, 20.1% CP, 2.5% Ca) were provided from 08:00 hours to 16:00 hours, and the PM diet (10.8 MJ AME/kg, 17.5% CP, 5.6% Ca) from 16:00 hours to 08:00 hours. AM/PM feeding demonstrated possible benefits for laying hen welfare, including the reduction in feather pecking and improved outdoor activity and bone health.

Phosphorus in poultry diets is mainly in the form of phytate, which may remain unused. The addition of high concentrations of phytase can reduce the use of inorganic phosphorus resources, and thus lower the production costs. The present study found that the dietary inclusion of higher concentrations of phytase could improve the performance of broiler chickens.
Severe weather events associated with climate change have several negative impacts on livestock, but livestock do contribute significantly to greenhouse gas emissions. Most climate-smart approaches to mitigate greenhouse gas emissions are inappropriate for low-and middle-income countries where food insecurity and the need to adapt livestock systems to a changing climate are greatest. This paper gives an discusses climate-smart approaches for enhancing livestock Productivity to simultaneously reduce greenhouse gas emissions, increase livestock adaptation to climate change and improve food security in low- and middle-income countries.

Cattle exhibit significant variation in growth performance, enabling the selection of superior animals. Efficient nitrogen use in cattle, which can be predicted through nitrogen isotopes in tail hair, correlates with improved growth performance. This study highlights how steers with better nitrogen use efficiency respond positively to a urea supplemented diet, demonstrating enhanced growth on low-quality feed. Identifying such cattle allows for more effective and economical feed and supplement strategies.

The use of dietary garlic to enhance ruminant productivity has gained attention in the animal production industry due to its several pharmacological properties. However, there are inconsistent results on the effects of dietary garlic on ruminant productivity. This meta-analysis demonstrated the efficacy of dietary garlic intervention in enhancing small ruminant productivity while reducing methane emissions.

The efficacy of plant bioactives in supporting health and productivity of lactating cows and growing ruminants under heat stress remains underexplored. This review provides an overview of existing studies to address this gap. Heat-stressed animals may experience reduced feed intake, compromised immunity, oxidative stress, and productivity losses. Some phytogenics have shown promise in mitigating these effects, especially in lactating cows. However, further research, particularly in pre-weaning calves and under different heat stress severity and durations is needed to validate these findings.

An adequate understanding of how the energy required to maintain a growing animal changes with body mass is critical to development of efficient animal production systems. Previously we reported that a cubic relationship existed between these variables; therefore, we aimed to determine whether causal factors could be identified that explained this finding. Protein turnover, fat turnover, and rate of growth explained the cubic relationship between maintenance costs and body mass, and identified the energetically optimal mass of a growing animal.

Melatonin implants have been used to improve the survival and growth of lambs, and the improvement of colostrum and milk quality. In this study, we have demonstrated that implanting ewes 30 days before lambing increased growth rates of lambs, particularly in males. Moreover, implanting lambs at 45 days of age produced the highest growth and feed conversion rates in the fattening period. Melatonin treatments pregnant ewes and lambs at weaning are promising methods for increasing productivity of lamb meat production.

GreenFeed units are widely used globally to measure methane emissions. In grazing systems, cattle may decrease their visitation frequency to these units, leading to an increased number of measurement days or animals required to precisely determine greenhouse gas emissions. In total, 12–18 measurement days and 9–19 animals are required to estimate methane emissions in grazing cows and heifers.

This study looked at the white clover inclusion in perennial ryegrass swards on a wetland soil type in the border midland and western region of Ireland. The focus of this study was to substitute chemical nitrogen (N) fertiliser applications with white clover as it can sufficiently support the N requirements of the sward due to its N fixation abilities. The results of the study found very successful clover establishment with significant savings in chemical N fertilier.

Higher replacement rates in dairy herd lead to increased costs associated with rearing and/or purchasing replacement heifers and greater greenhouse gas emissions from the herd. Reducing the replacement rate has the potential to enhance farm milk solids production and reduce emission intensity. The findings of this study underscore the importance of considering both environmental factors, such as greenhouse gas emissions, and economic aspects, such as net farm income, when evaluating and implementing strategies for sustainable dairy farming.

The liver function index (LFI) indicates liver status and may be key during the postpartum period in dairy cows. This study, which included two groups of cows with two dietary supplements, examined the relationship between the LFI, milk production and ovarian activity. Cows with LFI greater than zero were found to produce more milk at baseline and at 28, days and 89% of cows were in estrus within the first 90 days and had larger ovarian and follicle sizes.

This study aimed to evaluate existing methods for predicting methane emissions from beef cattle fed barley and wheat-based diets typical in Australian feedlots. All the tested equations were found to be inaccurate to methane emissions of feedlot cattle, underscoring the importance of developing methods with region- or country-specific data. To address this, the study developed new equations that showed better accuracy and precision in predicting methane emissions for cattle on barley and wheat-based diets.

The papers published in this Reearch Front comprise research outcomes from the National Agricultural Manure Management Program (NAMMP). This program was developed by a consortium of rural research and development corporations who recognised similar knowledge gaps in manure management systems across Australian intensive livestock production. These gaps included gathering information on the amount of greenhouse gas (GHG) emissions from different livestock and manure management systems, together with the sources and causes of GHG emissions in the different systems. The NAMMP consortium proved successful for both researchers and industry and is a model that should be considered for any future cross-sectoral programs.
