A Review on Non-Invasive Pregnancy Diagnosis in Wild Cats

Authored by Mostafa A Mahmoud

Many wild cats around the world are facing the danger of extinction due mainly to habitat destruction, poaching, illegal trade, inbreeding, diseases and conflict with humans. As a result, conservationists moved towards the application of ex-situ conservation programs through captive breeding to save endangered species for future introduction to their natural homes. However, breeding success of these cats in captivity relies largely to the availability of non-invasive techniques using urine and fecal samples to detect pregnancy hormones in the early stages of reproductive management. Wild cats are usually prone to stress when physically restrained for blood collection to carry out pregnancy tests. This stress jeopardizes the success of captive breeding of endangered cat species. Monitoring reproductive hormones in urine and feces provided an alternative and successful tool for reproductive management of these species without exposing the animals to stress or workers to the danger of handling big cats. The detection of prostaglandin F2 alpha and its metabolites PGFM (13, 14-dihydro-15-Keto-PGF2 alpha) in urine and feces using radioimmunoassay (RIA) or enzyme immunoassay (EIA) has been extensively used for this purpose and is a breakthrough in pregnancy diagnosis in wild cats. Further studies are needed to validate the technique in other non-felids species.

Review on the Reproductive Health Problem of Dairy Cattle-Juniper Publishers

Image
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Abstract Reproductive disorders have been found to be a major reason for decreased reproductive efficiency in cattle and consequently reproductive efficiency is the major determinant of lifetime productivity of cows. Among the major reproductive problems that have direct impact on reproductive performance of dairy cows are abortion, dystocia, retained fetal membrane (RFM), pyometra, metritis, prolapse (uterine and vaginal), anoestrus, repeat breeding and these results, in considerable economic loss to the dairy industry due to slower uterine involution, reduced reproductive rate, prolonged inter-conception and calving interval, negative effect on fertility, increased cost of medication, drop in milk production, reduced calf crop and early depreciation of potentially useful cows. It is very difficult to diagnose those problems by one particular disorder or symptom because there is interrelatio

Integration of Innovative Technology ‘Narmada Nidhi’ in Backyard Poultry Farming for Empowering Tribal Women Self-Help Groups-Juniper Publishers

Image
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES   Abstract The present study was conducted in six villages of Narayanganj and Niwas blocks of Mandla District. Data were collected through a structured interview schedule by personal interview method. For integration of Narmada Nidhi among tribal women SHGs extension interventions like awareness camps, exposure visits and trainings on poultry management were organized in the study areas. After proper extension interventions, 06 self- help-groups were formed and each group was provided with 50 Narmada Nidhi chickens to empower them. The study data revealed that, extension interventions lead to improvement in knowledge and attitude change among the members of SHGs. The each tribal SHGs were economically benefitted as they received an average income of Rs.17,032 during the 8 months study period. Proper extension strategies like awareness campaigns, exposure visits and training helps in capacity bui
