We conducted a longitudinal study to obtain baseline information about the health and growth of growing pigs raised by smallholder pig raisers in the Philippines, and to test constraints and opportunities to smallholder growing pig production that had been identified in a cross-sectional study [More, S.J., Lee, J.-A.L.M., Lañada, E.B., Taveros, A.A., Cotiw-an, B.S., 1999. Weight-for-age of growing pigs raised by smallholder farmers in the Philippines. Prev. Vet. Med. 41, 151-169]. Using monthly on-farm visits over 12-18 months at two sites, we collected data about 824 growing pigs raised in 115 separate herds. Weight-for-age (median value of 4.8 kg/month) was clustered strongly at the herd level, and the daily ration to growing pigs was substantially deficient (particularly in protein). Using repeated-measures and time-to-event analyses, we identified a range of animal- and herd-level variables associated with increased growth and health. These results confirm results from our earlier study, and suggest that improved nutrition and targeted extension on a range of management issues could be useful.
我们开展了一项纵向研究，以获取菲律宾小农户饲养的生长猪的健康和生长方面的基线信息，并测试在一项横断面研究中确定的小农户生长猪生产的制约因素和机遇[莫尔，S.J.，李，J.-A.L.M.，拉尼亚达，E.B.，塔韦罗斯，A.A.，科蒂万，B.S.，1999年。菲律宾小农户饲养的生长猪的体重与年龄关系。《预防兽医学》41卷，第151 - 169页]。我们在两个地点进行了为期12 - 18个月的每月一次农场走访，收集了115个独立猪群中824头生长猪的数据。体重增长（中位数为4.8千克/月）在猪群层面上高度聚集，且生长猪的日粮严重不足（尤其是蛋白质方面）。通过重复测量和事件发生时间分析，我们确定了一系列与生长和健康改善相关的动物及猪群层面的变量。这些结果证实了我们早期研究的结果，并表明改善营养以及针对一系列管理问题进行有针对性的推广可能会有所帮助。
