The feed additive Availa-ZMC was investigated for the ability to reduce lameness in broilers using 2 alternative models for inducing lameness. The mixture of organic trace minerals was effective in reducing lameness by 20% in the wire flooring model and 25% in the litter flooring model with the bacterial challenge. Lameness in both models is overwhelmingly attributable to bacterial chondronecrosis with osteomyelitis. The reduction in lameness was associated, at least in part, with enhanced intestinal barrier integrity mediated by elevated expression of tight junction proteins and stimulation of bactericidal killing of adherent peripheral blood monocytes obtained from the birds treated with Availa-ZMC. Lameness is a major animal welfare concern in broiler production. The wire flooring model and litter flooring model with the bacterial challenge are effective models for evaluation of management strategies for mitigating infectious causes of lameness.

This paper documents that children in rural Indonesia participate in a great variety of early childhood education pathways. Three key factors predict early education pathways: household wealth, mother’s education, and the quality of available services. We also find that children who enrolled in playgroup programs at age 3–4 followed by kindergarten programs at age 5–6 scored significantly higher on primary school tests than those enrolled only in playgroup programs or only in kindergarten programs. This suggests that the sequence of these pathways is important for future learning. We also provide illustrative estimates of the cost-effectiveness of different pathways. Refereed/Peer-reviewed

Using administrative data, this paper evaluates the early impact of introducing a performance-based component into Jakarta's long-standing school grant program on learning outcomes. The authors use difference-in-differences and regression discontinuity approaches to identify the component's impact on both government primary and junior secondary schools. Learning outcomes improved in primary schools at the bottom of the performance distribution, which narrowed the performance gaps between schools. However, the component had a negative impact on the better performing primary schools. Overall, primary examination scores fell slightly but this effect was only temporary. In contrast, the performance-based component improved examination scores in junior secondary schools. This impact seems to have been greatest among better-performing schools, thus widening the performance gap between these schools and those whose performance was worse. The data suggest that the main impact of the performance-based grant in terms of learning outcomes operated through an increase in competition among schools to earn the performance-based grant rather than through receipt of the actual grant funds.

The Millennium Development Goal for primary schooling completion has focused attention on a measurable output indicator to monitor increases in schooling in poor countries. We argue the next step, which moves towards the even more important Millennium Learning Goal, is to monitor outcomes of learning achievement. We demonstrate that even in countries meeting the MDG of primary completion, the majority of youth are not reaching even minimal competency levels, let alone the competencies demanded in a globalized environment. Even though Brazil is on track to the meet the MDG, our estimates are that 78 percent of Brazilian youth lack even minimally adequate competencies in mathematics and 96 percent do not reach what we posit as a reasonable global standard of adequacy. Mexico has reached the MDG—but 50 percent of youth are not minimally competent in math and 91 percent do not reach a global standard. While nearly all countries’ education systems are expanding quantitatively nearly all are failing in their fundamental purpose. Policymakers, educators and citizens need to focus on the real target of schooling: adequately equipping their nation’s youth for full participation as adults in economic, political and social roles. A goal of school completion alone is an increasingly inadequate guide for action. With a Millennium Learning Goal, progress of the education system will be judged on the outcomes of the system: the assessed mastery of the desired competencies of an entire age cohort—both those in school and out of school. By focusing on the learning achievement of all children in a cohort an MLG eliminates the false dichotomy between “access/enrollment” and “quality of those in school”: reaching an MLG depends on both.
