Estrus synchronization and fixed time artificial insemination (FTAI) in dairy buffaloes during seasonal anestrus

The aim of this work was to study estrus synchronization and fixed time artificial insemination (FTAI) in dairy buffaloes during season anestrus. One hundred thirty-nine dairy buffaloes in seasonal anestrus were divided in two groups as G1(n=66) and G2(n=73). The protocols for both the groups were the same until day (D)14:D0 administration of 2.0 mg estradiol benzoate and implantation of progesterone device (P4) for 14 days; D14 removal of P4 plus 150 mg of cloprostenol and 400 IU of equine chorionic gonadotropin. On D16, G1 received 10 mg of buserelin and G2 100 mg deslorelin acetate. On D17, both the groups were submitted to FTAI. Ultrasonographic examinations of ovaries were performed on D0, D14, D16 and D17. Results showed that pregnancy rates in G1 and G2 were 20 and 41% (p<0.05) and the ovulation rates were 16.6 and 37%, respectively (p<0.05). The dominant follicle (DF) diameter on D16 was 7.9 mm in G1 and 8.9 mm in G2 (p>0.05). Thirty-five percent of the animals in G1 and 54.1% in G2 showed a diameter DF greater than 8.0 mm on D16 (p>0.05). Thus, it could be concluded that the protocols synchronized the estrus, leading the concentration of the parturitions in the period of low milk production. Deslorelin was more efficient than buserelin due the higher percentage of DF ovulation and higher pregnancy rates.

Application of the concepts of agro-tourism, agricultural diversification and food and nutrition for the development of Caribbean communities with reference to standards and priority setting

Introduction There is a renewed call for a new approach to development with emphasis on community empowerment or participation, with the belief that more sustainable activities will be undertaken in those communities. Much of that call, however, is coming not from within the communities, but primarily from advocates of change who may have little to do with those communities. What then will the new approach bring apart from a change in who are the decision-makers? And how do we ensure that the change that is called for will, in fact, bring added benefits to the communities themselves? To be sure, there are some successful stories of a community approach to problem solving. However, there are also many more stories of project failures. Serious analytical work, therefore, needs to be done to determine the factors that promote a successful community-based approach; when this approach should be used; and the methodology that should be employed. In an attempt to determine these factors, a brief analysis will be made of some of the governing structures in the subregion and their possible impact on the proposed new approach. Some of the earlier efforts at stakeholder and community approach to projects will also be examined as well as the new development strategy that is prompting the call for this new paradigm. The new paradigm focuses to a large extent on decision-making and community empowerment. With few exceptions, it is short on the promotion of tangible activities that are based on the resource inventory of the communities. This is not surprising, since, as noted before, the advocates of community empowerment may have very little connection with the communities and, in most cases, are unfamiliar with the resource base. Hence, a theoretical case is made, suggesting more style than substance. Another obvious shortcoming of this new paradigm is its continued over- dependence on assistance from the outside to build communities. Externally funded projects, seminars and meetings outside of the communities and foreign technical assistance continue to dominate these projects. While, of course, all communities have basic common needs such as water, health, education and electricity, there is sufficient diversity within communities to allow for tailoring of activities and programmes such that their differences become assets. It is in that context, that agro-tourism activities, standards, agricultural diversification, food and nutrition and priority setting have been chosen as aspects and activities for promoting community development, drawing on the various strengths of communities, rural or urban.

Child poverty: a priority challenge

This issue of Challenges resumes the analysis of child poverty that was addressed in the first issue of the publication. The main article presents data on child poverty in Latin America, but explicitly measures it with a rights approach. This means considering children to be poor when at least one of their rights is unmet, or when they suffer at least one basic deprivation. Nonetheless, in child poverty, multiple deprivations occur simultaneously, reinforcing each other and undermining children's and adolescents' development.

How do driver compensation schemes affect bus system performance?: a comparison between fixed wage and "guerra por el boleto" in Santiago, Chile.

Two systems of bus driver compensation exist in Santiago, Chile. The majority of drivers are paid per passenger transported, which leads to drivers trying to maximize the number of passengers each one conveys. Some of these effects are beneficial, such as a more active effort to minimize the problem of bus bunching, while others, such as aggressive driving, can be harmful. Drivers are said to "race" and the term "War for the Fare" is commonly used. Drivers also pay freelance workers called "sapos" to provide spacing information. Similar phenomena occur in other Latin American capitals.The other system, a fixed wage, is used by 2 companies holding recently awarded concessions for routes feeding metro stations.This paper discusses, quantitatively and qualitatively, the effects of these two compensation systems on accidents, quality of service, attitudes of both users and drivers, and average waiting times for passengers.

Road safety: a priority issue for the United Nations

This issue of the Bulletin deals with road safety, which has become an urgent worldwide problem. Given the fact that road accidents are increasing, that they affect the planet's most vulnerable population (namely the lowest income groups in developing countries) and that this is becoming a genuine public health crisis, the United Nations has decided that it is urgent to address the matter. The World Health Organization (WHO) has therefore dedicated the World Health Day 2004 to road safety.Given the urgent need for action, the Chiefs of Transport of the five Regional Economic Commissions of the United Nations held a meeting in Geneva (September 2004), where they agreed to reinforce the studies and projects carried out in this area.Below is a summary of various information sources and initiatives adopted to assess and tackle this modern epidemic and offers a pessimistic outlook for 2020, when road traffic crashes will constitute the third cause of death unless serious action is taken from today.
