AN24213Mobilisation and replenishment of phosphorus reserves in Bos indicus cows. 1. Mid-pregnant mature cows post-weaning

R. M. Dixon 0000-0002-8107-9456, L. Castells, K. L. Goodwin, L. J. Kidd, S. T. Anderson, R. J. Mayer, P. Isherwood, D. M. McNeill and M. T. Fletcher
 

Cows often mobilise bone minerals during lactation when intakes of phosphorus are lower than requirements, but these must be replenished. Phosphorus-deficient cows replenished bone minerals post-weaning when fed a high-phosphorus diet. Replenishment occurred more rapidly in cows with low bone minerals, and when the diet provided sufficient metabolisable energy and protein for high-liveweight gain. Post-weaning P supplementation of cows in low P status is expected to at least partially replenish their bone minerals.

AN24183Balancing future food security and greenhouse-gas emissions from animal-sourced protein foods in Southeast Asia

R. S. Hegarty 0009-0005-7404-9370, T. P. Tee 0000-0003-4274-9178, J. B. Liang 0000-0001-6024-0856, H. Abu Hassim, M. H. M. Zainudin, A. A. Azizi, Y. Widiawati, S. Pok, S. C. L. Candyrine and N. D. Rusli
 

Southeast Asia’s forecast rise in human population and demand for animal-sourced food is likely to increase absolute greenhouse-gas emissions from the region’s livestock sector. There are substantial animal and feed management opportunities to suppress the increase in these emissions by improving animal productivity. Targeting a regional reduction in emissions per unit animal product (emission intensity) instead of absolute emissions offers a means to support food security, while controlling emission of livestock derived greenhouse gases.

AN24201Bitter compound quinine hydrochloride improved post-weaning pig performance in the absence of zinc oxide

Elisabet Garcia-Puig 0000-0001-6281-3275, Fan Liu 0000-0003-2644-2416, Rebecca Morrison, Maximiliano Müller 0000-0001-9598-1371, Allan Lisle and Eugeni Roura 0000-0002-9073-9946
 

Quinine shows promise in improving the sustainability of pig farming by enhancing piglet growth while addressing environmental concerns linked to zinc oxide. Our studies revealed that quinine, comparable to traditional supplements, not only boosts piglet growth but also does so independently of zinc oxide showing promise as a viable alternative. This finding suggests that quinine could play a crucial role in promoting more sustainable pig nutrition practices.

AN24281Comparing three filter-bag types for accuracy and precision of in sacco undigestible neutral detergent fibre determination of various dicotyledon forages

A. Jonker 0000-0002-6756-8616 and M. M. Della Rosa 0000-0001-8845-2797
 

Undigestible neutral detergent fibre (uNDF) has become a standard feed analysis overseas to properly quantify forage digestibility. However, this analysis is not available locally in New Zealand and the method implemented in our laboratory by using an alternative bag (F57) was not validated. The results of the current validation suggest that the F57 bag is suitable for uNDF determination, but that some further modifications to the protocol need to be made to improve the accuracy and precision of the uNDF determination.

AN24275Effects of fructo-oligosaccharides and Bacillus licheniformis on performance, nutrient digestibility, hematological properties, and organ development in weaned piglets

Fan Wu 0009-0008-4330-5193, Di Wu, Zhihui Chen and Fengyun Ren
 

Weaning stress can severely affect piglet growth, nutrient utilization and immune function. This study found that combining dietary supplements fructo-oligosaccharides (FOS) and Bacillus licheniformis (BL) significantly improved feed efficiency, nutrient digestibility, protein metabolism, immune-cell counts, and organ developments in weaned piglets. These findings have highlighted a sustainable, antibiotic-free strategy to support piglet development during the critical weaning transition, promoting healthier and more efficient pig-farming practices.

AN24146Frequencies of β-casein variants and their influence on genetic merit for production traits in Holstein cows

María Eugenia Caffaro 0000-0002-5814-2293, María Agustina Raschia, Daniel Omar Maizon and Mario Andrés Poli
 

There has been increasing global interest in producing milk free from the β-casein A1 allele because of the health benefits it may have. We evaluated the genetic variation in the bovine β-casein gene regarding A1-like and A2-like variants and demonstrated that the A2-like variant correlates with higher estimated breeding values (EBVs) for milk, protein, and fat yields, and lower EBVs for fat and protein percentages. Our findings contribute to evaluating the consequences on dairy performance of selection for the A2-like variant.

Vitamin D is particularly important for livestock reared indoors in intensive production systems, due to its low levels in dietary sources, intense development of the animals’ skeletal system and accelerated weight gain. We explored supplementing piglet diets with active vitamin D in its glycoside form. Adding these supplements to diets already containing adequate vitamin D did not further increase serum D concentrations, but did improve general health.

AN23298Breeding objectives and economic value of important traits of Abergelle goats kept under a smallholder production system in Tigray, Ethiopia

Kahsa Tadel Gebre 0000-0003-4348-6533, Fasika Agegnehu, Tesfaye Gebreselama Teweldemedhn, Solomon Abera Bariagabre and Tsige Hailay Hagos
 

Ethiopia is home to 52.4 million goats, which play a vital role in the livelihoods of resource-poor farmers. Despite their importance, goat production is often characterized by low productivity, largely owing to the absence of well-defined breeding objectives that address the needs and aspirations of farmers amidst various challenges. Therefore, breeding objectives developed through active farmer participation are essential to ensure the sustainability of breeding programs, increase flock profitability, and improve the livelihoods of goat keepers.

AN24251Perinatal lamb survival was not reduced by grazing forage oats

Susan M. Robertson 0000-0001-5129-2216, Michael A. Friend, Bruce Allworth and Marie Bhanugopan
 

Grazing of cereal forage by lambing ewes has reduced lamb survival compared with grazing legume pastures. This study compared moving ewes from a legume pasture to oats for lambing and found no reduction in survival in the Oats group compared with continued grazing of legumes. Producers may safely graze lambing ewes on oats when supplemented with calcium, magnesium and salt, and differences in lamb survival with forage type may be associated with the capacity to meet the energy requirements of ewes.

AN24321Forage lucerne for grazing dairy cows: effects on milk yield, milk urea and fatty acid composition

M. C. Mangwe 0000-0002-7533-1889, R. H. Bryant 0000-0002-5004-8147, P. Beckett, L. Tey, J. Curtis, R. Burgess and O. Al-Marashdeh
 

Ruminant milk components are increasingly recognised for human health benefits (e.g. functional fatty acid composition) or indicators of nutrient supply (e.g. milk urea). This experiment investigated the effect of including lucerne at 40% of the traditional diet of perennial ryegrass-white clover mix on milk production and composition. The findings showed that lucerne can improve dietary protein supply during periods of deficiency and increase the concentration of functional fatty acids in the milk of grazing dairy cattle.

AN24077Dietary fiber consumption by sows during pregnancy has effects on gut microbial composition and immunity of offspring

Hongyu Lu 0009-0004-4741-6190, Jian Wu, Qian Cheng, Muhammad Junaid, Yixiang Li, Yi Xiong, Xian Li and Jianhua Yan
 

Piglets face many survival challenges after birth, and maternal beneficial influences can aid in their survival. This study found that supplementing a sow’s diet during pregnancy with 3% purified fiber mixture could beneficially impact the piglets’ microbiota profile and immunity. These results can provide some theoretical support for the subsequent better development of weaned piglets.

AN24093Using alpacas as guardian animals in Australia: a survey of sheep producers

Paige Matthews 0009-0009-2012-598X, Emma Doyle 0000-0002-5255-2187, Amanda K. Doughty, Wendy Y. Brown and Jamie Barwick
 

The use of guardian animals to protect livestock is becoming an increasingly popular form of predator deterrent. This survey examined how Australian sheep producers use guardian alpacas. The producers believed that alpacas are an effective form of predator deterrent, noting their worth as guardian animals by increasing lamb survival. In addition, these findings have also provided knowledge, such as how these animals are being managed with sheep and information for producers looking to invest in guardian alpacas.

AN24270Early-life cold stress and broiler breeder age: effects on metabolism and performance in broiler chicks

Ludmyla Martins Moreira, Tainá Silva Brandão Lopes, Cesar Andres Guato Guamán 0000-0002-4963-6371, Lorena Salim Sousa, Matheus Barros Santini, Alexandre Rodrigues Cardoso, Lucas B. C. Santos, Fabíola Oliveira Paes Leme, Leonardo José Camargos Lara and Itallo Conrado Sousa Araújo 0000-0001-8882-3180
 

Cold stress during the first week of rearing negatively impacted broiler chicks from 29-week-old breeders compared with 42-week-old breeders, leading to higher corticosterone levels, and reduced yolk sac absorption and crop filling. Chicks from 42-week-old breeders showed better overall performance, with higher body weight and feed intake regardless of environmental temperature. The study highlights the importance of maintaining thermal comfort for optimal chick development, particularly that from younger breeder flocks, to mitigate stress, and improve viability and growth performance.

In the feedlot, during the latter phase of finishing, animals show lower efficiency because weight gain is more directed to fat than protein. Several strategies are used to change the gain composition during this phase, such as beta-agonist zilpaterol (ZH), but the effectiveness of ZH can be affected by several factors. This is the first study that has provided information that the effectiveness of ZH in fattening lambs is independent of the energy concentration in the finishing diets.

AN24203Factors influencing the variability in performance of cattle grazing tropical pasture

E. Charmley 0000-0002-4189-1861, G. J. Bishop-Hurley, C. S. McSweeney, R. Takeuchi, G. Martinez-Fernandez and S. Denman
 

The influence of rumen fermentation, diet selection and animal activity on variation in liveweight (LW) gain of growing cattle grazing mixed tropical pasture was found to be minimal. Small but significant differences were mostly observed in the wet season. In the absence of major differences in measured variables, it is speculated that variation in LW gain is due to unmeasured phenotypes such as efficiency of nutrient use or voluntary intake.

Research Front: National Agricultural Manure Management Program – Greenhouse Gas Mitigation Options For Intensive Livestock Industries

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.
