AN25081Effects of almond hulls on the chemical composition and in vitro ruminal protein degradation of lucerne silage

Selim Sirakaya 0000-0003-2733-1726 and Selma Büyükkiliç Beyzi 0000-0002-4622-0645
 

Almond hulls are a significant by-product produced in quantities roughly double that of the kernel. The elevated tannin concentration is a limiting factor in their application in food and feed. Incorporating almond hulls into lucerne silage enhances the protein utilization efficiency of lucerne while reducing the tannin content in the hulls. Incorporating almond hulls into lucerne silage provides a dual advantage.

Huixin Xing, Chao Ma, Xiaoli Wang, Yan Zhao, Yudong Shang, Hengxing Ba 0000-0003-0882-8841 and Chunyi Li
 

Deer hard antler button (HAB), a traditional Chinese medicine, has been valued for its anti-inflammatory properties for centuries. This study demonstrated that HAB extract has stronger anti-inflammatory effects than deer hard antler shaft (HAS) extract, supported by cellular, animal model experiments, and metabolomics analysis. By identifying key bioactive compounds, the findings provide a scientific basis for the traditional use of HAB and highlight its potential applications in promoting health and well-being.

AN24358Insights into the pathogenesis of catastrophic spontaneous humeral fractures in first-lactation dairy cows

A. S. Wehrle-Martinez 0000-0002-3515-9164, K. E. Lawrence, P. J. Back, C. W. Rogers 0000-0002-4253-1825, M. J. Gibson 0000-0001-5970-4289 and K. E. Dittmer 0000-0002-1813-2197
 

Catastrophic spontaneous humeral fractures in young dairy cows have introduced significant challenges to New Zealand’s dairy industry, affecting animal welfare and farmers’ livelihoods. This review identifies poor bone formation and excessive bone removal as likely key risk factors leading to osteoporotic bones that fracture. Ensuring cows receive proper nutrition during key growth periods might help prevent these fractures and support a healthier, more productive dairy industry. Further research is essential to fully tackle this issue.

AN24340Impact of tree integration in crop–livestock systems with varying nitrogen rates

Luiza de Souza Carneiro, Luiza Chiezi Mendes, Debora Rodrigues, Vanderley Porfírio-da-Silva and Laíse da Silveira Pontes 0000-0002-3906-3047
 

Incorporating trees into crop–livestock systems (ICLS) plays a vital role in mitigating climate change by sequestering carbon in plants and soil. Our study showed that integrated systems can yield up to 573 kg/ha in areas typically fallow in winter; however, integrating beef heifers grazing cool-season grasses with immature Eucalyptus grandis trees negatively affected forage production, animal performance and tree quality. These results highlight the need for careful selection of trees, planting density, and arrangement to optimize the benefits of ICLS.

AN24303Metagenomic comparison of the microbial load colonizing lucerne hay and gum astralagus (Astragalus glycyphyllos) in ruminants

Mehtap Güney 0000-0002-0613-3600 and Sükrü Önalan
 

In this study, the digestion, fermentation profile and the microbiota associated with two different quality roughages (Astragalus glycyphyllos and lucerne hay) in the rumen were investigated in vitro. The composition and diversity of the microbiota colonizing the rumen significantly affect the digestion and fermentation of feeds, and thus the growth performance of animals. It was observed that these results are very important in terms of improving the efficiency of nutrient utilization of roughages in the desired direction.

AN24346Can soil and tree carbon sequestration maintain zero net emissions grazing?

A. Macdonald 0009-0000-7842-3087, J. Court, R. Meyer, M. Wootton, E. Kantor, R. Keenan, H. Stewart and R. Eckard 0000-0002-4817-1517
 

The inclusion of carbon sequestration in trees and soils to offset greenhouse gas emssions (GHGe) in agricultural carbon accounts, also known as carbon insetting, is a rapidly growing area of interest. Through a livestock enterprise case study, we demonstrated that although soil and tree carbon sequestration can produce low net emissions systems, they cannot maintain zero net emissions indefinitely. Whereas GHGe are continuous over time, sequestration eventually plateaus, further establishing the need for methods that avoid GHGe.

AN24258Effects of AM/PM feeding on behaviour, range use and welfare indicators of free-range laying hens

Afsana A. Jahan, Hiep Thi Dao 0000-0002-3093-1207, Md Sohel Rana, Peta S. Taylor, Tamsyn M. Crowley and Amy F. Moss 0000-0002-8647-8448
 

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.

AN24017Dietary microbial 6-phytase concentration effects broiler growth, short-chain fatty acid profile, and intestinal histomorphology

Hamid Raei 0000-0003-4853-9251, Fatemeh Azari Ghaleh Joogh, Shahram Golzar Adabi 0000-0001-9483-1611 and Mohammad Amir Karimi Torshizi 0000-0002-8141-4904
 

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.

AN24215Climate-smart approaches for enhancing livestock productivity, human nutrition, and livelihoods in low- and middle-income countries

Adegbola T. Adesogan, Mulubrhan Balehegn Gebremikael, Padmakumar Varijakshapanicker and Diwakar Vyas 0000-0002-7657-0267
 

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.

AN24210Use of 15N abundance in tail hair to predict feed efficiency and response to a urea supplement in young cattle fed a tropical grass forage

B. C. Fraser, K. Eyre 0000-0002-8270-9827, J. B. Gaughan, G. Wijffels and L. F. P. Silva 0000-0003-3271-9864
 

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.

AN23386Role of plant bioactive compounds in improving ruminant resilience to heat stress challenge

Farhad Ahmadi 0000-0002-8760-053X, Hafiz A. R. Suleria and Frank R. Dunshea
 

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.

AN24228Metabolic costs related to protein turnover, fat turnover, and rate of gain determine the energetically optimal size of growing sheep

Michael R. Murphy 0000-0002-9090-8359 and Bruce M. Hannon
 

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.
