A cohort study was designed to observe and follow up mortality in lambs and kids in 88 flocks of sheep and goats under the traditional production system in five villages within the coastal savanna zone of Ghana over a 2-year period. The overall mortality rates for kids and lambs were 30.8% and 33.5%, respectively. Significantly higher proportions of kids (80.2%) and lambs (75.6%) up to 3 months of age died compared to kids and lambs from 4 to 12 months of age. The differences in mortality rates, either between male and female kids and lambs or between single-born and multiple-birth kids and lambs, were not significant. The odds ratio (OR) and relative risks (RR) for lambs and kids, on the basis of sex and birth types, were not significant; neither were the values obtained for attributable risk, attributable fraction, population attributable risk and population attributable fraction. The overall mortality rate on the basis of species of animal was not significant. At the village level, significant differences in the proportions of mortality on the basis of sex were seen in two villages. At Akotokyir, more male lambs (54.2%) died compared to females (27.6%), while at Apewosika more female lambs (42.2%) died compared to males (16.7%). The only significant difference in mortality proportions on the basis of birth type at the village level was seen at Apewosika, where more single-born kids died (52.8%) compared to kids born with sibling(s) (28.4%). The significant ORs for mortalities were 3.10 for male lambs at Akotokyir, 3.35 for female lambs at Apewosika and 2.82 for single-born kids at Apewosika. The corresponding RRs were equally significant. On the basis of species, significantly more lambs died at Akotokyir (44.2%) and Kwesimprah (44.7%) compared to kids. The implications of these findings are discussed.  相似文献

A study was designed to identify factors perceived by veterinarians and veterinary technicians as likely to promote private veterinary practice in Ghana. The participatory appraisal approach was used. The response rates were 88% (n = 90), 100% (n = 9) and 86% (n = 200) for government field veterinarians, private veterinarians and government veterinary technicians, respectively. Significant proportions of government field veterinarians (67%, n = 79), and veterinary technicians (64%, n = 167) were willing to go into private practice if the necessary push was given. Factors perceived as likely to motivate them to go into private practice included availability of capital to cover start-up costs; provision of a vehicle; prospect of higher income; availability of loans with low interest rates; availability of credit facilities from suppliers; stable macroeconomic environment with low interest and inflation rates; high pet, poultry and livestock populations at locations earmarked for private practice; leasing of vacant government premises for use as clinic and for accommodation; and enforcement of legislation on private practice, especially that against moonlighting by government veterinarians and technicians. These should be considered and used in the promotion of private veterinary practice in Ghana.  相似文献

Lack of adequate financing was a major reason for the privatization of veterinary services in Jamaica in 1992. The belief was that, with privatization, funding of animal health services delivery would improve, since staff numbers and clinical activities undertaken by the Veterinary Division were reduced. However, analyses of data revealed that, in most cases, privatization neither improved nor stemmed the declines, that had started before privatization, in the measures or indicators used. It was concluded that privatization of veterinary services did not result in any appreciable improvement in the financing of the delivery of public-sector animal health services in Jamaica in the short term.  相似文献
