AN24167A review of extended lactation in dairy cows managed in high-input and pasture-based farming systems

Kerst Stelwagen 0000-0001-6931-5084, Ina (J. B.) Pinxterhuis, S. Jane Lacy-Hulbert and Claire V. C. Phyn
 

A literature review of extended lactation (EL) in dairy cows managed under intensive- and pasture-based farming conditions was conducted. EL may improve reproductive performance, animal health and welfare and reduce the number of ‘surplus’ calves. Implementing EL in a pasture-based system is more challenging, given its reliance on the annual pasture growth cycle and will require strategically feeding supplements to maintain milk yield of cows. The potential benefits of EL in such a system warrant more research.

AN24155The liveweight, carcasses and meat quality of intact and castrated male lambs reared under a pasture-fed Australian production system

Shawn R. McGrath 0000-0002-4737-4267, M. Bruce Allworth, James Stephens, Michelle L. E. Henry and Benjamin W. B. Holman 0000-0002-8458-4511
 

Intact male (ram) lambs are often discounted by meat processors because of their perceived defective meat quality and additional processing requirements. Intact male lambs grew faster during the pre-weaning period and achieved heavier liveweights at slaughter compared with castrated male (wether) lambs. Untrained consumer sensory scores ranked the meat of wethers as being more tender and of greater overall liking than the meat of ram lambs – even though few objective meat quality parameters were observed to be affected by castration.

AN23258Effects of dietary phytase supplementation on growth performance, nutrient digestibility, and blood metabolites of weaned piglets

Elick Kinara, Habeeb Tajudeen, Abdolreza Hosseindoust, Jun Young Mun, Sang Hun Ha, Se Rin Park, Choon Han Lee, Lakshmibai Vasanthakumari Bindhu, Justin Tan and Jin Soo Kim 0000-0002-9518-7917
 

Phytase plays a crucial role in the nutrition of young pigs. Incorporating phytase into young-pig diets helps alleviate the anti-nutritional effect by catalyzing the hydrolysis of phytic acid. As a result, bounded phosphorus and other minerals becomes more accessible for absorption by the pig’s gut, thereby enhancing nutrient utilization and promoting better growth performance.

AN24255Assessment of loliolide extracted from Biserula pelecinus, present during in vitro oocyte maturation, on fertilisation and embryo development in sheep

A. A. Amir, A. A. Algreiby, J. M. Kelly, D. O. Kleemann 0000-0002-4346-7730, Z. Durmic 0000-0001-7300-043X, G. R. Flematti, D. Blache and G. B. Martin 0000-0002-1905-7934
 

It is important to test whether new forage plants contain secondary compounds that affect reproduction. We added extracts of Biserrula pelecinus to the medium used to mature sheep cumulus–oocyte complexes and assessed oocyte maturation, cleavage rate, blastocyst rate, hatching rate, blastocyst efficiency and total blastocyst cell number. One fraction tended to reduce blastocyst rate, but loliolide, the most abundant compound in that fraction, did not affect any measure of embryo development.

AN24309Modelling the impact of increasing supplementary feed allowance on predicted sheep enterprise production, profit and financial risk across southern Australia

A. L. Bates 0000-0002-4984-3581, S. M. Robertson 0000-0001-5129-2216, S. R. McGrath 0000-0002-4737-4267, M. B. Allworth and G. Refshauge
 

Supplementary feeding sheep is an important nutritional and reproductive management practice, but can be expensive. Increased financial risk has often been associated with increased supplementary feeding and was apparent in the current study in association with mating season, but was not linked to breed. Producers may be able to improve the production, profit and financial risk of an enterprise through increased supplementary feeding, but this will be dependent on breed, input costs, commodity prices and location.

Manure deposition on livestock export voyages contributes to air ammonia (NH3), impacting human and animal health. This study examined how bedding application rate (BAR) and air change rate (ACH) affect air NH3 and pad NH4+ levels in housed beef cattle. Higher BAR improved pad conditions by reducing pH, moisture, and NH4+, while increased ACH lowered air NH3. Optimising air changes and bedding use can effectively mitigate NH3, offering practical solutions to enhance human and animal welfare during livestock transport.

AN24176A new analytical procedure to replace the outdated Weende proximal feed ingredient analysis paradigm is long overdue

Gene M. Pesti 0000-0002-3311-1079
 

Since the 19th century, when little was known about chemical composition of feeds, gross feed analysis for trade and estimating energetic contributions has been based on the Weende method (moisture, crude protein, crude fibre, ether extract, ash and nitrogen-free extract). A new, Armidale Method, is proposed here. It consists of 13 chemical categories based on modern knowledge of feed chemistry (moisture, true protein, nonprotein nitrogenous compounds, neutral and polar lipids, sugars, oligosaccharides, starch, pectin, lignin, hemicellulose, cellulose, and ash).

This paper belongs to Animal Science Reflections and Collection: Recent Advances in Animal Nutrition - Australia 2025.

AN23138Analysis of alternative national development pathways for the cattle system in Ethiopia: linked economic and animal systems (LEAS) model

Emerta Aragie 0000-0002-4982-9923 and James Thurlow
 

Livestock sector growth assumptions should be looked at from the perspective of the dynamics in the domestic and global economy, and uncertainties around the driving forces of the transition. This study used the case of Ethiopia to provide an analysis of alternative national development trajectories relating to the prospects of growth performance and urbanisation. It generates insights into the importance of integrating economy-wide and livestock-system models to provide a risk-based approach to the prospects of the livestock sector.

AN24106Analysing the effects of feeding black soldier fly on broiler growth performance: a meta-analysis

Zafar Hayat 0000-0002-0975-1594, Tuba Riaz 0000-0002-8559-6346, Youssef A. Attia, Faran Hameed and Fahad Javaid Siddiqui
 

Due to the growing global demand for more sustainably produced animal protein, there is an intensive search for alternative feeds to replace soybeans, which increases the cost of feed due to limited availability in some countries. Black soldier fly shows great potential for substituting soybeans in poultry diets as it is a sustainable and protein-rich alternative to conventional protein sources for broilers. A meta-analysis was conducted to test the hypothesis that it enhances growth performance and can reduce competition for plant protein sources among humans and animals.

Long-term production efficiency gains and changes to production have significantly improved the environmental performance of Australian pork over time. This study was a long-term trends analysis of Australian pork between 1980 and 2022 and found that greenhouse gas emissions and freshwater consumption fell by 74% and 90% over the analysis period. Although novel low carbon production systems were identified, the rate of environmental improvement was found to have slowed since 2010.

We compared Saanen and Saanen × Boer kid meats and found that the Saanen × Boer crossbreed contributes to increased carcass yield and greater acceptance of the meat by consumers. When comparing different slaughter ages (30 and 60 days), we observed that the carcass fat content increased and lipid oxidation in the meat decreased when the kids were slaughtered at 60 days of age.

AN24194Xylanase and phytase supplementation of Moringa oleifera diets: effects on the performance, egg quality and blood profile of laying hens

G. M. Macambira 0000-0002-0277-5286, C. B. V. Rabello, H. S. H. Oliveira, M. J. B. Santos, D. A. Silva, A. C. F. Santos, A. G. Ribeiro, O. S. Lins Júnior, L. D. N. Sousa, I. L. C. Máximo and M. V. Navarro
 

The use of alternative foods, as well as additives that improve the use of these foods for birds, is an area of study that is constantly growing owing to the constant search for ingredients that make feed cheaper. Several studies have already used Moringa oleifera as an alternative food in poultry diets; however, studies that combine this food with exogenous enzymes, additives that can improve its use and bring benefits to the animals’ health, are still almost non-existent.
