Abstract

This study determined the carcass composition of Lao indigenous buffalo (Bubalus bubalis) and cattle (Bos indicus), then examined trends in bovine meat marketing following review of records of beef production and prices in the two major cities of Luang Prabang (LPB) and Xieng Khoung (XK) provinces in northern Laos. Samples from 41 buffalo and 81 cattle (n = 122) were collected from animals slaughtered in May-June 2014, with live weights, carcass weights and other carcass-related variables collected. The animals were classified into four age cohort groups (<2, 2-<4, 4-6 and >6 years) with quantitative and dichotomous qualitative traits determined. There were significant differences in buffalo and cattle predicted mean carcass weights between age classification categories (p = 0.003 and 0.001) but not in dressing percentages (p = 0.1 and 0.1). The carcass weight of buffalo was 104 (±23.1)-176 (±12.0) kg compared to 65 (±8.7)-84 (±6.5) kg of cattle, with dressing percentages of 37-40 and 39-42 %, respectively. Despite an average bovine meat price increase of 42-48 % between 2011 and 2013, there was a reduction in the numbers of large ruminants slaughtered in the surveyed cities of LPB (11 %) and XK (7 %), with bovine meat availability per person of 5.2-6.6 kg (LPB) and 3.0-3.8 kg (XK). Improving the sustainability of the bovine meat supply in Laos requires a systems approach involving improvements to animal health and production, livestock marketing, plus the critical development of improved slaughterhouse facilities enabling a meat-processing sector to emerge. This development pathway is of particular importance for building the capacity of Laos to reduce food insecurity and alleviate the poverty of its largely rural smallholder community.

摘要

本研究确定了老挝本土水牛(水牛属)和黄牛(印度牛)的胴体组成,然后在回顾老挝北部琅南塔省(LPB)和川圹省(XK)两个主要城市的牛肉生产记录和价格后,研究了牛肉市场的趋势。2014年5月至6月期间,从屠宰的动物中采集了41头水牛和81头牛(n = 122)的样本,记录了它们的活重、胴体重以及其他与胴体相关的变量。这些动物被分为四个年龄组(<2岁、2 - <4岁、4 - 6岁和>6岁),并确定了其数量性状和二分定性性状。水牛和黄牛在不同年龄分类组之间预测的平均胴体重存在显著差异(p = 0.003和0.001),但屠宰率无显著差异(p = 0.1和0.1)。水牛的胴体重为104(±23.1)- 176(±12.0)千克,而黄牛为65(±8.7)- 84(±6.5)千克,屠宰率分别为37 - 40%和39 - 42%。尽管2011年至2013年间牛肉平均价格上涨了42 - 48%,但在接受调查的琅南塔市(下降11%)和川圹市(下降7%),大型反刍动物的屠宰数量有所减少,人均牛肉供应量为琅南塔市5.2 - 6.6千克,川圹市3.0 - 3.8千克。提高老挝牛肉供应的可持续性需要一种系统方法,包括改善动物健康和生产、牲畜销售,以及关键的改进屠宰场设施,以发展肉类加工部门。这条发展途径对于建设老挝减少粮食不安全和缓解其主要为农村小农户社区贫困的能力尤为重要。
