In endangered donkey populations, reproductive performance is one the most important areas to study, provided its connection with conservation opportunities. Among traits, knowledge on evolution of seminal qualitative and quantitative parameters may achieve a particular relevance given implication improved or more efficient fertility fecundation chances. The aim present study was model gonadoso...
The Plio-Pleistocene evolution of Equus and the subsequent domestication of horses and donkeys remains poorly understood, due to the lack of phenotypic markers capable of tracing this evolutionary process in the palaeontological/archaeological record. Using images from 345 specimens, encompassing 15 extant taxa of equids, we quantified the occlusal enamel folding pattern in four mandibular chee...
The aim of this study was to evaluate the effect of two different extenders (Skimmed Milk Glucose SMG or Lactose Egg Yolk LEY) on physical characteristics and fertility of fractionated donkey semen cooled at 5°C. For this, four Pêga donkeys were used as semen donors. The sperm rich fraction of the ejaculate was diluted preparing insemination doses containing 400 x 10 6 motile spermatozoa in a v...
Maps, tables and graphs are presented to illustrate trends in donkey populations in the world, with emphasis on Africa, Asia and Latin America. Most data derive from information collated and published by the Food and Agriculture Organization of the United Nations (FAO). Although national estimates of donkey populations are seldom accurate, they illustrate broad trends. There are estimated to be...
In Senegal, several areas provide great potential for agriculture and animal production, but African animal trypanosomosis (AAT) is one of the major constraints to the development of more effective livestock production systems. A study was conducted to assess the current situation of AAT in this country. Surveys were carried out between June 2011 and September 2012 in four different areas: Daka...
In this study, we detected Leishmania (Viannia) braziliensis infection in equids living in endemic regions of cutaneous leishmaniasis. To determine the role of these animals in the Leishmania cycle, we used two approaches: serological and molecular methods. Antibodies to the parasite were assayed using the Enzyme Linked Immunosorbent Assay (ELISA). Blood samples were collected and tested by pol...
myiasis caused by the larvae of c.bezziana has been reported in man, cattle, cats, water buffalo, sheep, goats, horses, donkeys, dogs, camels and elephants from asia and africa. although human infestation o with this parasite is commonly found in cattle-raising areas, cases of urogenital myiasis are rarely reported. this is the first cases report of urogenital infestation with the larvae of c. ...
BACKGROUND Nagana (African Animal Trypanosomiasis-AAT) and tick-borne diseases (TBDs) constrain livestock production in most parts of sub-Saharan Africa. To this realisation, Uganda government set up an African trypanosomiasis (AT) control unit, which among other activities generates national tsetse control priority maps using apparent tsetse density data. Such maps underestimate mechanically t...
Background Theileria equi is a tick borne protozoan parasite which causes piroplasmosis among equines worldwide. The present study was aimed to determine seroprevalence of T. equi in donkeys, horses, and mules from two equine populated districts (Peshawar and Charsadda) of Khyber Pakhtunkhwa (KPK), Pakistan. Methods A total of 393 equine (195 horses, 194 donkeys and 4 mules) serum samples wer...
Domestication of the donkey from the African wild ass transformed ancient transport systems in Africa and Asia and the organization of early cities and pastoral societies. Genetic research suggests an African origin for the donkey, but pinpointing the timing and location of domestication has been challenging because donkeys are uncommon in the archaeological record and markers for early phases ...
