The results of an artificial insemination experiment
carried out in the suburban area of N’Djamena are here reported. Two methods of
synchronization (Norgestomet combination/estradiol/PGF2a/PMSG and
were used with Chadian zebu and crossed breeds in 2007 and 2008. Females were
inseminated after induction of estrus with semen of French Normand breed. The
fertility rate was low with PGF2a (29.41%).
The results obtained with the combination of several hormones were better
(66.66%). The survival rates of crossbreeds were particularly low, 40% in 2007
and 33.33% in 2008, mainly due to the traditional management of the herd and
the lack of technical support. The insemination cost of a cow was 39,550 F CFA
in 2007 with PGF2a and
59,200 F CFA in 2008 with the method consisting of combining of four hormones.
The cost of producing a calf in those two years was very high, 134,470 F CFA in
2007 and 118,400 F CFA in 2008.
The aims of this
study were to investigate the food safety knowledge and practices of food handlers
and to assess the sanitary conditions of attieke production units in the South of C?te d’Ivoire. A cross-sectional study was
conducted during 4 months in 2012 in 7 localities and data were collected using
questionnaire and observation checklist and microbiological analysis of hands.
A total of 775 attieke production
units were involved in this survey. Seventy-one percent (71%) were located on
public domains and only 70 production units (9%) used septic tank as a mean of
final deposal for liquid waste. Hygiene conditions and practices of food handlers
in attieke production units were
inadequate. The presence of specific microorganisms such as Staphylococcus aureus, Klebsiella pneumoniae, Enterobacter agglomerans, Citrobacter youngae, Klebsiella oxytoca and Citrobacter freundi was indicative of a degree of ignorance on the part of food handlers towards
proper hygienic practices.
