AN23418Association of a non-synonymous variant of MLH3 gene involved in meiotic recombination with conception rate of Japanese Black cattle

Thu Nu Anh Le 0009-0008-5146-5517, Trung Ba Nguyen, Takehito Tsuji, Takayuki Ibi, Shinji Sasaki and Tetsuo Kunieda

Conception rate, which is an important parameter to evaluate female fertility, has been gradually decreasing in Japanese Black cattle during the past decades. In this study, we found a non-synonymous variant of the MLH3 gene that has been reported to be involved in meiotic recombination rate is also significantly associated with conception rate. This novel variant is suggested to use as a potential marker for selecting the Japanese Black cattle for improving fertility.

AN23438Nutritional composition of black soldier fly (Hermetia ilucens) larvae reared on vegetable wastes: effects on growth of village chickens

Zaid Ahmad 0000-0001-6359-3585, S. K. Ramiah, Eddy S. Jamein, Zulkifli Idrus, Idris H. Lokman, Faiz M. A. Amirul, Samad A. A. Fadzlin, Afifi A. A. Ghani, Mohd Zamri-Saad, Anuraga Jayanegara and Hasliza Abu Hassim 0000-0002-7119-6560

Black soldier fly larvae are a promising alternative ingredient of poultry feed. They might be able to replace soybean and fishmeal because they contain high protein and fat, and are also rich in vitamins and minerals, and because partial replacement of soybean and total replacement of fishmeal produce no adverse effect on the growth performance of village chickens. Therefore, they are a suitable replacement of these traditional ingredients in poultry feed.

AN23416Goat meat supply and demand in Vietnam: global context and opportunities and risks for smallholder producers

Luisa Olmo 0000-0001-8175-8216, Huu Van Nguyen, Xuan Ba Nguyen, Thi Nga Bui 0000-0001-9998-3227, Cuc Thi Kim Ngo, Viet Don Nguyen 0000-0002-4273-0672, Nam Hoang, Luis Emilio Morales 0000-0001-6935-9634 and Stephen Walkden-Brown 0000-0002-0638-5533

Goats are a resilient animal that can thrive in areas where cattle and sheep can’t, making them an ideal species for rural communities. Our analysis of goats in Vietnam found that there are cultural and economic drivers that promise continued growth in demand, creating plentiful opportunity for rural communities to continue developing goat production to improve their living standards. These trends justify increased action on marketing, biosecurity and environmental impacts, to ensure the sustainability of goat production.

AN23412Disease as a constraint on goat production in Lao PDR and trade to neighbouring countries: a review

P. P. Jayasekara 0009-0009-4528-7344, W. Theppangna, L. Olmo 0000-0001-8175-8216, T. Xaikhue, C. Jenkins 0000-0002-5966-072X, P. F. Gerber 0000-0002-8343-8299 and S. W. Walkden-Brown 0000-0002-0638-5533

Disease is one of the major issues affecting goat production in Lao PDR. Although only a limited number of studies have been published on diseases in Lao goats, a review of the available literature is desirable, given that goat production is rapidly expanding among smallholder farmers. This review article brings together the disease-related studies for a better understanding of health and production in Lao goats.

Increased movement of livestock and products in the Greater Mekong Subregion (GMS) has enhanced disease transmission risk, increasing transboundary animal-disease (TAD) incursions and one health (OH) concerns. This has coincided with increasing awareness of greenhouse-gas emissions (GHGe) from livestock, especially contributions to ecosystem health (EH) concerns from large ruminants. Projects addressing biosecurity, vaccines, disease surveillance, feeding systems and national emergency disease-response capacities are required, and private-sector investments developing climate-resilient livestock systems to support the livelihoods of poor rural communities in the GMS should be encouraged.

Goats fulfil unique subsistence and socio-cultural roles in smallholder farmers’ livelihoods in Laos. Increasing goat productivity can improve conditions of farmers’ livelihoods, but it is unclear which approaches are most appropriate for resource-constrained farmers who balance multiple farming enterprises on small plots of land. Some approaches to increasing goat productivity are more applicable in Laos than are others. These approaches should be prioritised by the Government of Laos’ policy and development projects to benefit the widest cohorts of farmers.

Canola meal (CM) is a potentially important protein source for poultry. The amino acid profile of CM is reasonably well balanced, but digestibility of amino acids is key to the nutritional value of CM. Amino acid analysis and in vivo digestibility assays are costly and time consuming. The aim of this study was to determine whether the digestible amino acid content of CM could be deduced from its crude protein content, which is routinely determined.

AN23398Strengthening the role of innovation brokers in the livestock advisory services system of Pakistan

H. M. Warriach 0000-0002-5391-9956, M. Ayre, R. Nettle 0000-0001-8347-6693, K. Height, H. Iqbal, A. Aziz, K. Hayat, A. Afzal, S. Majeed, A. Kumbher and D. M. McGill

A well-functioning farm advisory services play a vital role in the improvement of livestock sector in low-income countries. We explored the ways in which capacity building through a particular training and professional-development intervention can lead farm advisors to act as innovation brokers within the advisory services system of Pakistan. The results are highly instrumental in strengthening farm advisory services and the role of farm advisors in low-income countries to support farmers in improving their livelihoods.

Sorghum-fed broilers has reduced performance compared with those fed corn- and wheat-based diets. This difference has been attributed to the presence of anti-nutritional factors in sorghum. The present findings showed that anti-nutritional factors in sorghum and protein meals have an impact on the additivity of digestible nutrients in mixed diets, giving rise to associative effects.

AN23394Antibacterial properties of oil extracts of black soldier fly larvae reared on bread waste

Mung Kwan Shu, Cheuk Ming Li, William Eduardo Furtado, Qianjun Huang, Sophie St-Hilaire and Ákos Kenéz 0000-0002-9041-3452

The concern over the spread of antimicrobial resistance has prompted a search for alternative solutions. Black soldier fly larvae extracts possess natural antibacterial properties that can potentially inhibit bacterial growth. Rearing black soldier fly larvae on a bread waste-based substrate enhanced their lauric acid yield, resulting in significant antibacterial efficacy against E. coli; hence, incorporating larval oil into animal feed holds the potential for reducing antibiotic drug usage.
