This study concerns the effect of improving health status on testicular development of local guinea fowl reared under natural photoperiod. Two groups of 100 males of guinea fowls chicks were used for the study. One group (T1) served as control and did not received any treatment while the second group (T2) received several treatments including anti-stress, trichonomacid, anticoccidies, dewormer and vaccination against New Castle disease. Results showed no difference in body weight at 28 weeks of age between the 2 groups. However at 24 weeks of age birds in T2 had higher values for mean testicle weight (286±70 versus 148±34 mg). Parameters for seminiferous tubes were also higher for T2 birds: mean volume (74±0.3 versus 63±6.6% of testicle volume), mean diameter (126±24 versus 89±13 μ) and mean length (6.4±0.4 versus 5.1±1 mm). Improved health status also increased population numbers of spermatocytes I, rounds spermatides and interstitial cells. Differences were significant at 20 weeks of age for Sertoli cells. Spermatogenesis starts at 24 weeks of age for T2 birds but at 28 weeks for T1 birds. © Asian Network for Scientific Information, 2011.

Sclerocarya birrea, multipurpose plant is characteristic of the Sahel-Sudanian savanna and is widespread in West Africa. Although this species has a high socio-economic importance, its genetic organization was not well characterized in Burkina Faso. In this study, the intra and interpopulation genetic diversity of S. birrea was determined by random amplified polymorphic deoxyribonucleic acid (RAPD) markers. We found a high average of intra population genetic diversity (He = 0.20) among S. birrea populations. The species populations were also characterized by their low genetic differentiation (Gst = 0.24), indicating a significant exchange of genes flow between populations. The whole population was clustered into four groups without reference of site and climatic zone. The Mantel test suggested that genetic distances between populations were not correlated to geographic distances. Our results strongly suggest that the structure and the level of this species' genetics diversity may be due to its mode of dissemination involving ruminants. © 2012 Academic Journals.

This study was designed to identify the external parasites and to evaluate their effects on mortality, growth and reproduction of poultry in the traditional rearing system in the sub-humid zone of Burkina Faso. Identification of external parasites was done on 500 of each species of chicken, guinea fowls and turkeys. For the evaluation of the effects of external parasites on the productivity of poultry, 324 chicks that were 6 weeks of age were randomly divided into 12 groups of 27 chicks each. Four of the groups was assigned at random to receive a treatment against external parasites (ET), 4 other groups were similarly assigned to receive a treatment against external parasites and another treatment against internal parasites (EIT). The 4 remaining groups were not treated against parasites (NT). Two mice species Liperus gallinae and Monopon gallinae have been found on both chicken and turkeys while Goniodes gigas was the only mice species parasiting chicken. The lice Echidnophaga gallinacea and the tick Argas persicus have been found to parasite chicken. Results of productivity trial showed that mortality due to effects of external parasites amounted to 13.9% of non treated poultry. Live weight of male birds increased from the base line of 850 g of the non-treated birds by 9.8% (950±164.3 g) due to treatment against external parasites and by 44.5% (1250±133.1g) due to treatments against both external and internal parasites. Live weight of female birds increased similarly from 952.5±238.7 g by only 3.8% (980.5±36.2 g) due to treatment against external parasites and then by 13.5% (1081.6±160.2 g) due to treatment against both external and internal parasites. Likewise, age at first egg decreased from 28 weeks to 25 weeks with treatment against external parasites and further to 24 weeks with both treatments. Egg weight also increased from 47 to 48.Og due to treatment against external parasites and further to 48.5g due to both treatments. External parasites increase mortality rate and reduce growth rate of chicken. © Asian Network for Scientific Information, 2011.
