Experiments were performed on 11 adult Red Sokoto goats (RSG) with the aim of determining their diurnal temperature fluctuations during the harmattan season. The rectal temperatures (RT) of goats were recorded with a standard clinical thermometer every hour from 06:00 to 19:00 hours. The RT of goats rose gradually from its minimum value of 38.3+/-0.1 degrees C at 06:00 hours and attained its peak value of 39.2+/-0.1 degrees C at 18:00 hours (P < 0.001). Thus, the RT values rose concurrently with increase in ambient temperature. The overall mean RT obtained was 38.7+/-0.1 degrees C. The diurnal fluctuation in the RT of the goats was 1.9+/-0.1 degrees C. There was a highly significant correlation between time of day and RT values (r = 0.947, P < 0.001). The results indicate a diurnal rhythm in the RT of the RSG, which agree with the established pattern of fluctuations in the RT of other breeds of goats. The high diurnal range of 1.9+/-0.1 degrees C confirms that the harmattan season is thermally stressful to the RSG. 相似文献

We evaluated the indirect fluorescent-antibody (IFA) test and complement-fixation (CF) test for diagnosis of equine piroplasmosis in the absence of a gold standard. Using Evan's blue, we estimated the specificity of the IFA test on a parasite-free, field horse population to be 98% (95% confidence interval=97, 99). We observed an excellent test agreement (kappa=0.83) between two collaborating laboratories when the IFA test was performed on identical samples from an endemic area. Using Bayesian analysis with informative prior probability distributions, we estimated the sensitivity of the IFA test to be 92% (95% probability interval, PI=81, 98), and specificity to be 95% (95% PI=88, 99). The CF test sensitivity and specificity estimates were 28% (95% PI=15, 47) and 99% (95% PI=96, 100), respectively. We found the IFA to be superior to the CF test, and the inclusion of Evan's blue in test protocol improved the performance of the IFA test. We conclude that the IFA test for Babesia caballi is a sensitive and specific test for the diagnosis of equine piroplasmosis. 相似文献

The indirect fluorescent antibody (IFA) test for Theileria equi was evaluated to assess test's suitability for the serological diagnosis of equine piroplasmosis, to provide performance parameters for the purpose of test validation, and to compare it with the complement fixation (CF) test. Using a protocol that included Evan's blue, the specificity of the IFA test was estimated at 99.0% for T. equi by the classical method of analysis, and 96.6% by the Bayesian method. The use of Evan's blue in the test protocol increased test specificity and contributed to an excellent test agreement between two collaborating laboratories (kappa = 0.96). Using Bayesian analysis, the sensitivity estimate for the IFA test was 89.2%. The CF test sensitivity and specificity estimates for T. equi were 63.1 and 96.4%, respectively, as determined by Bayesian analysis. The IFA test was more sensitive than the CF test but the specificity estimates were similar. 相似文献

This experiment was carried out to evaluate the effect of reduced dietary crude protein (CP) levels supplemented with or without exogenous phytase on growing pigs. Six dietary treatments arranged in a 3 × 2 factorial arrangements of 3 CP levels (containing 14%, 16%, and 18% CP) supplemented each with or without 5,000 FTU/g phytase enzyme. Thirty growing pigs (average weight of 17.80 ± 0.10 kg) were allotted to the six dietary treatments in a complete randomized design. The final weight, daily weight gain, and feed conversion ratio (FCR) increased significantly with increasing CP levels. While, phytase supplementation improved (p = .044) FCR in pigs. Total solid and volatile solid content of the slurry were higher (p = .001) in pigs fed 14% and 16% CP diets supplemented with phytase when compared with other treatment groups. Concentration of methane gas emitted was lowest (p = .001) in the slurry of pigs fed 14% CP diet with or without phytase and those fed 16% CP diet with phytase supplementation. In conclusion, reduction in dietary CP levels resulted in reduced weight gain and poor FCR. While, reduced CP with phytase supplementation reduced concentration of methane gas emitted. 相似文献

A simple random sampling technique was used to select 20% of the extension officers in North West Province, South Africa. Data on knowledge levels and perceived effect of climate change on extension delivery were collected and analyzed using frequency counts, percentages, and multiple regression analysis. The results show that a wide range of knowledge levels exists on climate change issues related to causes, effect, vulnerability, and mitigation and that extension officers will have to address new skill requirements for farmers, the need for specialized extension services, and changing and diversified livelihoods. The results have several implications for training and educating extension officers on climate change issues. 相似文献

A large sample size technique was used to select 30 employers each from the private and public sector to examine their perception of the competence of agricultural graduates. Data were collected with a structured questionnaire and analyzed using means, standard deviation, and t test. The results show that, for 16 crop production tasks, public agroemployers were favorably disposed to competence in 4 tasks, while private employers were not favorably disposed to competence in any tasks. Both public and private employers were not favorably disposed to competence in farm engineering tasks. The Botswana College of Agriculture curriculum should be overhauled to better prepare graduates for employment. 相似文献

Growth response, nutrient digestibility and cecal microflora of 80 male, mixed breed weaner rabbits fed with varying dietary inclusions of sorghum milling waste (SMW) was investigated. Four experimental diets were formulated such that SMW was included at 0 (control), 100, 200 and 300 g/kg, respectively. Each dietary treatment was performed on 20 rabbits. Feed intake increased (P < 0.05) while final live weight and feed conversion ratio of rabbits decreased (P < 0.05) following increased dietary inclusion of SMW. Rabbits fed with 100 and 200 g/kg SMW had similar feed conversion ratios, weight gain, crude fiber, dry matter and crude protein digestibility values. Rabbits fed with 300 g/kg SMW recorded the lowest (P < 0.05) hot carcass weight, dressing percentage and rack weight. Similar dressing percentage and rack weight were recorded for rabbits fed with control diet, 100 and 200 g/kg SMW. The weight of cecal content increased (P < 0.05) with increased dietary inclusion levels of SMW. Rabbits fed with 300 g/kg SMW recorded the lowest (P < 0.05) coliform and lactobaccillus counts. Dietary inclusion of up to 200 g/kg SMW supported improved growth response and carcass yield without imposing any detrimental effect on cecal microflora. 相似文献

A needle-free delivery system was assessed as a route for providing quick, safe, and effective vaccination against avian influenza (AI). Two groups of chickens were vaccinated with a commercially available inactivated H5N3 virus vaccine delivered either with a needle-free device or with the conventional syringe-and-needle method recommended by the vaccine manufacturer. The kinetic aspects of seroconversion, peak antibody levels, and antibody titers were measured by a combination of an indirect enzyme-linked immunosorbent assay and the hemagglutination-inhibition test and were all found to be similar in the 2 groups of chickens. We conclude that the needle-free delivery system could result in effective immunization against H5N1 AI epidemics and pandemics in chickens. 相似文献
