With the exception of the domestic cat, all felid species (Felidae) are currently threatened with extinction in their natural habitat. To develop effective and optimal wild cat conservation programmes with assisted reproductive technology (ART) it is necessary to combine advances from different disciplines of science, starting from the biology of the species, through research into the population and habitat, assisted reproductive technologies, establishment of gene banks, developing bioinformatic systems, and ending with biodiversity and endangered species management. In the last few years knowledge of felid reproduction has expanded considerably thanks to comparative studies utilising the domestic cat as a research model for endangered wild cats. Basic reproductive techniques utilised in both domestic cat breeding and rescuing wild felid populations that are threatened with extinction include semen collection and cryopreservation, artificial insemination, oocyte collection, in vitro maturation, in vitro fertilisation, somatic cloning, and embryo transfer. The main directions in which assisted reproductive technologies are being developed in wild cat conservation implementations and the contribution of Polish research centres in advancing these methods are presented.

Tahani K. Altowairqi | Manal E. Shafi
An overview of freshwater fish variety worldwide and the variables influencing trends in variation between and within river basins are given in this review. Continental freshwater ecosystems are highly diverse and species-rich, housing nearly 18,000 species of fish (>50% of all fish species) in [J Adv Vet Anim Res 2024; 11(2.000): 356-366]

Indigenous sheep are highly adaptable and widely distributed in different regions of Bangladesh. They are famous for their tolerance to harsh environmental conditions, low demand for feed, and disease resistance with minimum or no housing and management facilities. Ample indiscrimi¬nate research reports and case studies on the native sheep of Bangladesh have been published. Nonetheless, a comprehensive review of reproductive and productive performances, as well as their various morphometric physiognomies and climate resilience capabilities, is lacking. This review was designed to explore and summarize the available research reports on indigenous sheep to highlight the gaps and provide an updated database for the future research plan for sustainable native sheep production in Bangladesh. It covers studies on sheep biodiversity, their adaptabil¬ity to the local environment, morphometric features, feeding and nutrition, reproduction and production performances, diseases and health management, and the problems and prospects of sheep farming in Bangladesh. Due to the increased demand for animal protein, especially red meat, the scope of sheep farming increases along with that of other large and small ruminants. The vital constraints of sheep production in Bangladesh include insufficient feed and fodder sup¬ply with its high prices, higher disease occurrence with low or no management practices, kid mortality, and a poor marketing channel with the lower popularity of sheep meat than goat meat. Future research would be a prerequisite to measuring the impact of native sheep on household economies and food security during the year, evaluating the other challenges, and finding out the possible interventions in the fields of nutrition, reproduction, and health management.

اظهر المزيد [+] اقل [-]What are we losing? Are the personality traits of Italian autochthonous cows different from those of cosmopolitan breeds? النص الكامل

Objective: This study assessed personality traits in five cattle breeds (Bos taurus), two cosmopolitan (Holstein Friesian and Brown Swiss) and three endangered Italian autochthonous (Varzese, Rendena, and Modenese). Our aim was to provide an evaluation of the personality dimensions obtained by our questionnaire in order to compare some Italian autochthonous breeds with the cosmopolitan one. Our choice fell upon the comparison of the Varzese, the Modenese, the Rendena, the Brown Swiss, and the Holstein Friesian because the genetic selection at the base of the typical attitudes has induced different characteristics, and as a consequence, detectable differences in personality can be expected between the populations. Materials and methods: A personality questionnaire was completed by milkers/owners for each subject involved in this study. The milking staff involved in the study have been working with cows for over 20 years; they have experience with numerous breeds, and therefore, can be considered expert evaluators since they certainly have an appreciation of the full range of cow behavior. Results: The milkers assessments analysis found breed differences in dairy cattle, showing that certain personality traits are more marked in certain breeds in terms of curiosity, friendliness to milkers, and responses to unknown people. Conclusion: This pilot survey shows the usefulness of questionnaires in cattle personality studies, highlighting some peculiarity of the endangered breeds.
